DETAILED DISCUSSION OF THE INVENTION
[0095]
[0096] The lower section 4 of the body 2 of the present invention has first 13 and second 13 ends defining a length 14, the first 13 end having a receiver 16 formed therein along its length, said receiver 16 having an inner wall forming an inner diameter 17 and depth 17 formed to receive 21, via threaded 15 opening 15 at said second 13 end of the vaporizer section 7, a heater cartridge 12.
[0097] The heater cartridge 12 comprises a threaded 11 base 11 having an outer wall forming an outer diameter 11 with a groove 19 for an O-ring 19 for a sealed threaded connection with the vaporizer section, the base further having formed thereon and wrench flat 23. The heater cartridge 12 further comprises a thermal conductor sleeve 19 (an aluminum or stainless steel sleeve is used in the present example depending on the type of heater used, although other thermally conductive material could be used depending on the application and circumstances of use), having an outer diameter 22 and length 22, the thermal conductor sleeve formed to contain therein a heater core, for example, a PTC heating element (
[0098] The heater core receives power via the conduit adapter, which engages a cylindrical socket 8 formed in the heater core base 11 via cylindrical plug 8 emanating from conduit adapter 8, to facilitate pivotal adjustment 32 as required for the device to have conduit approach from any direction as the adapter can be rotated 360 degrees. As earlier discussed, the PTC heater cartridge 53 is self-regulating so does not require a temperature sensor or cutoff, and includes a built-in power connector 53 in its base, while the enhanced NTC heater cartridge 54 incorporates a built-in thermal cut-off 55 and temperature sensor 55 in addition to the power connector 55.
[0099] A screen or mesh 27 formed of thermal conducting material (for example, a Stainless Steel, 60 Mesh Screen roll formed to be situated in the space 25 or gap between thermal conductor sleeve and the receiver sidewall) is thereby provided in the space 25 between the outer diameter 22 of the thermal conductor sleeve enveloping the heater core, and the sidewall forming the inner diameter 17 of the receiver 16, the mesh 27 provided to facilitate enhanced heat transfer via the heater core and thermal conductor sleeve 22 outer surface, to fluid flowing 29 through the vaporization chamber 24.
[0100] A fluid inlet 28 is provided at about the second end 13 of the body 2 of the vaporizer 7 section to receive a flow of fluid 33 (wet gas or the like) and direct same to the vaporization chamber 24 to vaporize entrained liquids or the like and facilitate fluid flow 29 therethrough (contacting thermal conducting mesh 27) utilizing heat emanating from the conductor sleeve 19 via the heater core to facilitate heat transfer to the fluid flowing through the passage forming the vaporization chamber 24, such that fluid flowing therethrough is heated as it traverses the length of the vaporization chamber 24, so as to facilitate the vaporization of any liquids entrained therein to gas, which gas flows out of the vaporization chamber via outflow passage 31 in the vicinity of the first end 13 of vaporizer body 2, via clearance 30 between the distal tip of the conductor sleeve, and distal end 18 of receiver 16 from opening 14. As shown, outflow passage 31 is situated along the longitudinal axis 13 of vaporizer body 2, and situated between regulator section 6 and vaporization chamber 24.
[0101] When compared to the applicant's prior art, GENIE brand vaporizer product (distributed by A+ Manufacturing Inc and shown in
[0102] The vaporized sample 33 leaves the vaporization chamber and flows via to the adjustable regulator section 6 where pressure reduction occurs, so as to provide a regulated, lower pressure sample. The adjustable regulator 35 shown in the present exemplary embodiment comprises a spring biased regulator seat 35, piston 36 and adjustable mechanism 36 in the form of a threaded bolt or the like to adjust spring bias of a helical compression spring 36 applying bias on the piston 36, similar in operation of the prior art GENIE GHR brand heated regulator top regulator R section shown in
[0103] The lower pressure sample then travels back down into the heated vaporizer portion of the body, for post-heat exchange passage 34 after regulation before flowing from the device via outlet 28, which is situated between regulator section 6 and vaporization chamber 24 so as to receive residual heat from said vaporization chamber for post-heat exchange, and in parallel alignment with post heat passage 31.

[0105] Continuing with
[0106] Each piston chamber 43, 43, 43 has its own access port comprising a threaded opening 44, for receiving a threaded cover 45 with O-Ring 45 or other seal to provide to a sealed chamber, each chamber sized to receive a modular conditioning component, shown in the present exemplary embodiment as modular regulator components 46, 46, 46 therein respectively, with each said each modular regulator component 46, 46, 46 inserted 49 or otherwise placed in to their respective piston chamber 43, 43, 43, and sealed therein via threadingly engaging a respective cover 45 with O-ring 45 to the threaded opening 44 of each piston chamber.
[0107] Applicant assignee's patents U.S. Pat. No. 10,690,570 or U.S. Pat. No. 8,220,479B1, the contents of which are incorporated herein via reference thereto, teaches examples of modular single stage pressure ratio regulator (see for example 38 in
[0108] Each pressure reducing component in the form of a modular regulator in the present exemplary embodiment of the invention of
[0109] Each modular regulator component 46, 46, 46 comprises a piston housing which is formed to receive pressure reducing piston provided to reduce the pressure of wet gas flowing therethrough, providing a pressure cut of the fluid flowing into the vaporizer to facilitate the flash vaporization thereof, providing vaporized gas, which can then be further conditioned downstream, i.e., flowing to pressure regulator (such as an adjustable regulator) as further discussed herein.
[0110] Each modular regulator component 46, 46, 46 will provide a staged pressure drop or pressure cut of the fluid flowing therethrough, with multiple staged components in series, such as the present invention, to provide a more gradual pressure reduction, to diminish the excessive amount of cooling from taking place in single stage systems (many times the Joule-Thomson (JT) cooling that takes place when a gas is reduced in pressure).
[0111] A further advantage of the present drop-in modular component feature is that it allows ready customization of the desired pressure drop to facilitate the desired vaporization or other conditioning required, by choosing the appropriate specification pressure reducer component apparatus, which can offer different pressure reduction characteristics while maintaining similar exterior dimensions/configuration, but with different pressure reduction characteristics, allowing the user to choose the desired pressure reduction characteristic for the particular installation, and insert or drop in the appropriate pressure reducer component into the pressure reduction component receiver of the unit.
[0112] The first, second, third and fourth regulator stages, stages 1-3, being drop in modular regulator components and the fourth being manually adjustable thereby provide customizable, stepped-pressure reductions so as to avoid or diminish Joule-Thomson effect cooling and associated condensation of the vaporized sample flowing therethrough, the figure further illustrating utilization of the PTC heater cartridge of the present invention shown provided therein, as well as the passage from the vaporizer to the first regulator stage, and passage from the third regulator stage to the fourth regulator stage.
[0113] The radial design configuration of stage 1-3 modular regulator components 46, 46, 46, respectively, of the present invention, are provided in a unique radial configuration situated along a radial plane 47 just upstream the vaporizer, and below the upper 4 vaporizer body 2 (the body constructed of thermally conductive material such as stainless steel), and utilizes this position intermediate the vaporizer and fourth stage, to exploit the pre-heat characteristics of the treated fluid having just been heated via heater cartridge 12 as well as their physical proximity to same and associated heat zone (as well as exploiting the thermal conductivity of the body 2 to transfer heat from the vaporizer area to the regulator components) provides an enhanced thermal efficiency, as opposed to the prior art which relies upon heat from relatively distant heater block design such as shown in the prior art (for example, see
[0114] Rather, the sample gas is exposed directly to the thermal conductive sleeve 19 or jacket heated by the heater cartridge 12 before reaching the pressure reduction stages, with the distance from the three staged pressure reduction stages and the heater cartridge 12 being minimal AND uniform as to stages 1-3, as opposed to the greater distance of the regulator(s) as provided in the prior art as well as non-uniform heat transfer in prior art due to increasing distance for each stage (for example see
[0115] The radial design of the present embodiment of the invention of
[0116] In addition, one can simply remove a regulator and enclose the chamber via the threaded cover 45 with seal where reconfiguration, maintenance, or even removal of a particular stage, when a reduction stage is not required. Another type of conditioning or sensing component may be put in its place.
[0117] Following passage through the third piston chamber 43 and associated regulator component 46 (when used), the reduced fluid then flows via passage 39 to the final, adjustable regulator 50 for a final pressure reduction or regulation, said adjustable regulator 50 having the same components and operation as the adjustable regulator of the single-stage, first embodiment of the invention shown in
[0118] After passage through the final stage (the adjustable regulator 50), the pressure reduced, vaporized fluid 52 flows through passage 51, which passage directs the fluid back toward the heat source, so as to provide post regulator heat exchange of the fluid before it flows out of the device via outlet 42, which is situated along the same radial plane 47 as the stage 1-3 regulator components 46, 46, 46, respectively.
Regulator with Radially-Configured Multi-Stage Serial Flow
[0119] Continuing with the
[0120] The present invention also provides optional pre-heat or pre-conditioning capacity, as well as a final stage comprising an adjustable regulator, the present exemplary embodiment of the device illustrating a multi-stage regulator configured to provide stepped-pressure reductions so as to avoid or diminish Joule-Thomson effect condensation of wet gas, as well as the method of using same, as will be discussed further herein.
[0121] It is noted that, while the present illustrated example of the present invention teaches three radially situated modular conditioning component chambers (also referenced as piston chambers) to receive drop in fluid conditioning components to provide three stages of stepped fluid conditioning, the actual number of stages can vary depending on the application and circumstances of use.
[0122] As used herein, a drop-in modular conditioning component or piston refers to unitary or integrated element(s) having a generally uniform outer configuration to facilitate insertion into a receiver or chamber (referenced as piston chamber or component chamber) formed in the body of the device to receive such a component's outer or exterior configuration, and in the present (non-limiting) example, being of a generally piston-shaped or cylindrical exterior form. As used in this context, the term piston refers solely in an exemplary context to a general geometric configurationsuch as a generally cylindrical or elongated profile-and is not intended to imply or require the presence or function of an actual piston or reciprocating element, unless expressly stated otherwise. Further, the modular conditioning component or piston as can be utilized in the present invention can exist in other configurations including a non-radial, rectilinear form, for drop in to a chamber or receiver formed to receive same.
[0123] The drop-in feature means that the modular conditioning component (shown in the form of a single-stage regulator) can be added to or removed from the piston chamber without the need for permanent attachment, specialized tools, or significant assembly or disassembly whether in the field or lab, thereby enabling an easier implemented, less intensive modular installation, replacement, repair, or reconfiguration, etc., anywhere, including in the field and other less than ideal conditions outside of a lab or service facility.
[0124] The modular conditioning component is not intended to be restrictive as to its functionality or purpose (even though the exemplary embodiment comprises a regulator function), and it is intended that the component can vary depending on the application. Accordingly modular conditioning components comprise devices performing any of a variety of functions as described throughout the present application, including but not limited to, fluid regulation, flow reduction, filtration, separation, monitoring, or temperature adjustment/moderation/control. The term piston-shaped is understood to include both generally cylindrical forms as well as other elongated profiles suitable for cooperative engagement with the walls of a piston chamber. The term piston chamber is likewise not intended to be limiting as to operation, and should be construed as a configurational description of a component dimensioned and formed to receive and operatively interact with the drop-in component configured to receive same.
[0125] Continuing with the
[0126] The piston chambers (shown as first 143, second 143 and third 143 piston chambers) are shown serially engaged via respective flow passages, in a radial arrangement in the lower 104 section of the base, the piston chambers (143, 143, 143) formed to receive one or more modular conditioning components (as will be more fully discussed herein), the overall (assembled) device 101 shown as having a cylindrical outer surface 105 defining an outer diameter 105 with wrench flats 109, 109 formed in the upper 104 and lower 104 sections, respectively, to facilitate engagement (and tightening or loosening) via an open-ended wrench or the like.
[0127] A fluid inlet 128, which can comprise, for example, an NPT inlet connection 128, is provided at about the second end 103 of the lower section 104 of the body 102 to receive a flow of fluid 133 (wet gas or the like) therein.
[0128] The base 107 at the second end 103 of the body 102 has formed therein a flow or pre-treatment chamber 112 having an inner wall 112 forming an inner diameter 112 a threaded 115 opening 115 formed to receive a cover 116 with O-ring 116 or other seal to selectively provide a access port to chamber 112. The pre-treatment chamber 112 can be sized and configured to receive modular conditioning components, for example those similar to the aforementioned piston chambers 143, 143, 143, so as to receive a drop-in modular conditioning component such as described herein to provide optional a pre-conditioning stage for fluid passing therethrough before reaching said serially-linked piston chambers 143, 143, 143.
[0129] Alternatively, and as shown in the present illustrated example, instead of adding a drop-in modular conditioning component, the pre-treatment chamber 112 as shown in the figures has situated therein a plug 113 of heat conductive material such as stainless steel or the like, the plug 113 having dimensions sized to encompass much of the volume of said pre-treatment chamber 112, while providing a clearance 114 between the inner wall 112 of the chamber and the outer wall 114 of the plug 113, so as to provide a flow passageway 129 to facilitate the flow of fluid 133 from the inlet 128 therethrough, and where the base 107 and plug 113 are heated via a block heater or the like, so as to provide a heated chamber 112 and passageway 129, fluid 133 flowing therethrough is pre-heated as a pre-treatment stage in the present system, as will be further discussed infra.
[0130] It is noted the pre-treatment chamber 112 may also serve as simply a pass-through for fluid flowing therethrough, when pre-treatment is not required. In such an application, the plug 113 (if situated in chamber 112) may remain but not be heated, or may be removed with the pre-treatment chamber sealed to allow flow of fluid through an empty chamber 112. Alternatively, a conditioning or sensor component may be inserted in the chamber.
[0131] Flow passage 141 provides a passage of fluid from the pre-treatment chamber 112 (which may or may not pretreat the fluid flowing therethrough as discussed above and herein) to the first stage 120 of four serially-connected conditioning stages, stages 1-3 (120, 120, 120 respectively) shown situated in a radial positioning relative one another relative to a common center point 147, each stage each comprising piston chambers 143, 143, 143 formed to receive drop-in, modular regulator components 146, 146, 146, respectively, the piston chambers 143, 143, 143 each having independent access ports or openings situated along the outer radial surface 147 of the cylindrical body 148 of the device, said piston chambers 143, 143, 143 situated in serial, spaced relationship relative to one another along a common plane 147 and linked via passages 141, 141 from one to the other in series, respectively. As shown, said plane 147 is positioned perpendicular to said longitudinal axis 108 of the body 102 of the device 101 with the piston chambers 143, 143, 143 shown in lateral orientation towards the side of the body.
[0132] As used herein, the term piston chamber is not intended to be limited to a chamber formed specifically to receive a piston or a particular shape or functionality, and can be also referenced as a modular conditioning component chamber or the like. Further, piston chamber is intended to be construed broadly to encompass various shaped chambers, receivers or the like to contain various diverse components, including but not limited to receiving a modular conditioning component, pressure reduction component, a heat transfer component or other application as described in the present application, or no component at all, to function as a pass-through, for example. The use of the term is for convenience and clarity, and should not be interpreted as restricting the scope of the invention to any particular element, embodiment or configuration unless expressly stated otherwise.
[0133] Each modular conditioning component chamber or piston chamber 143, 143, 143 has a threaded opening 144, for receiving a threaded cover 145 formed to engage O-Ring 145 or other seal to provide an access port to a sealed chamber 142, each said chamber sized to receive a drop-in modular conditioning component (or piston) in the form of a modular regulator component 146, 146, 146 therein respectively, with each said each component 146, 146, 146 inserted 149 or otherwise placed in to their respective piston chamber 143, 143, 143, and sealed therein via threadingly engaging a respective cover 145 with O-ring 145 to the threaded opening 144 of each piston chamber. As discussed, in the present exemplary embodiment, each modular conditioning component comprises a regulator or pressure reducer, to provide staged pressure reduction of fluid flowing serially therethrough, so as to prevent Joule-Thompson condensation of wet gas (gas having entrained liquid therein), and provide pressure reduced wet gas for analytical testing or other application.

[0135] In the present example wherein there is provided staged pressure reduction via serial flow of wet gas through conditioning stages 120, 120, 120, a pressure reducing component in the form of a modular regulator or conditioning component in the present exemplary embodiment would utilize a reduction piston or the like configured to provide a fixed pressure reduction, selected from a collection similar sized of modular regulators configured to provide various pressure cuts which could be inserted into the modular conditioning chamber(s) a/k/a piston chamber(s) of the present device. Each modular regulator component of the present invention is selected to provide the desired pressure cut ratio for each stage. The configuration of the piston housing of a particular component may be customized to accommodate both the inside dimensions required to contain the required piston within the piston housing, as well as the outer dimensions required to fit within the chamber to which it to be inserted.
[0136] Continuing with the figures, each modular conditioning component in the present exemplary embodiment is provided in the form of drop-in modular regulator component 146, 146, 146 for the present application, and comprises a piston housing which is formed to receive pressure reducing piston provided to reduce the pressure of wet gas flowing therethrough, providing a pressure cut of the fluid flowing into the vaporizer to facilitate the flash vaporization thereof, providing vaporized gas, which can then be further conditioned downstream, i.e., flowing to pressure regulator (such as an adjustable regulator) as further discussed herein.
[0137] Each modular regulator component 146, 146, 146 is selected to provide a staged pressure drop or pressure cut of the fluid flowing therethrough, with multiple staged components in series, such as the present invention, to provide a more gradual pressure reduction, to diminish the excessive amount of cooling from taking place in single stage systems (many times the Joule-Thomson (JT) cooling that takes place when a gas is reduced in pressure).
[0138] A further advantage of the present drop-in modular component feature is that it allows ready customization of the desired pressure drop to facilitate the desired vaporization or other conditioning required, by choosing the appropriate specification pressure reducer component apparatus, which can offer different pressure reduction characteristics while maintaining similar exterior dimensions/configuration, but with different pressure reduction characteristics, allowing the user to choose the desired pressure reduction characteristic for the particular installation, and insert or drop in the appropriate pressure reducer component into the pressure reduction component receiver (also described as piston chamber or modular conditioning component receiver of the unit.
[0139] Of the first 120, second 120, third 120 and fourth regulator stages, stages 1-3 comprise drop in modular conditioning components (in this case, in the form of regulator components) and the fourth being a manually adjustable regulator 150, thereby providing customizable, stepped-pressure reductions so as to avoid or diminish Joule-Thomson effect cooling and associated condensation of the vaporized sample flowing therethrough, the figure further illustrating utilization of the PTC heater cartridge of the present invention shown provided therein, as well as the passage from the vaporizer to the first regulator stage, and passage from the third regulator stage to the fourth regulator stage.
[0140] The radial design configuration of stage 1-3 modular regulator components 146, 146, 146, respectively, of the present embodiment of the invention are situated in a unique radial configuration along the radial plane 147 just upstream the pre-treatment chamber 112 (where utilized) provide an efficiency of space, while exploiting exploit any pre-heat characteristics where a heater is used, such as a block heater 154 mounted to the base 107 of the unit to heat said unit, providing heat to said pre-treatment chamber 112 and any heat conducting plug 113 situated therein to provide a heated pretreatment chamber flow passageway 129 resulting in heated, pre-treated fluid flowing therefrom. Further the relatively close physical proximity of the treatment stages 120, 120, 120 can result in heating of same when the body 102 is formed of heat conducting material such as stainless steel, exploiting the thermal conductivity of said body 102 to transfer heat from the vaporizer area to the conditioning stages 120, 120, 120.
[0141] Unlike prior art systems, the unique radial design of the present invention, with the associated first, second and third piston chambers 143, 143, 143 respectively, each having an independent access means via an access port 159, 159, 159, each comprising a threaded opening 144 with removeable cover 145, provides easy, individualized access to each chamber and associated modular conditioning component or piston in a relatively small overall footprint, to allow for individual changes and/or maintenance as required even in the field, as opposed to having to require partial or full removal and disassembly of the unit to change or repair even an individual regulator stage, or replace O-ring seals as required on an individual basis as in various prior art systems.
[0142] For example, even in the field, one can easily access the drop-in modular conditioning component within a chamber via adjacent access port, perform the desired operation (replace, reconfigure, remove, etc.) then close the access port via a threaded cover 145 with seal, thereby providing for relatively easy reconfiguration, maintenance, or even removal of a particular stage (when a reduction stage is not required) or another sample conditioning or sensing component may be added in its place.
[0143] Following passage through the third piston chamber 143 and associated regulator component 146 (when used), the reduced fluid then flows via passage 139 to the final, adjustable regulator 150 for a final pressure reduction or regulation, said adjustable regulator 150 having the same components and operation as the adjustable regulator of the single-stage, first embodiment of the invention shown in
[0144] After passage through the final stage (the adjustable regulator 150), the pressure reduced fluid flows through passage 151, which passage directs the fluid back to the lower section 104 of the body so that where said body is heated such as via a heater block (
[0145] With the mounting of a block heater 154 (for example, NTC or self-regulating) to the base 107 (as shown in
[0146]
[0147]
[0148] While the present invention illustrates a radially-configured, multi-stage, modular conditioning device each staged formed to receive drop-in modular conditioning components which are easily and independently accessible for each stage, the stages shown in a relatively compact, space saving radial configuration, it is emphasized that the radial configuration is not intended to be limiting, and can be provided in other configurations with similar efficiencies, as will be detailed further herein.
Regulator With Stacked, Multi-Stage, Serial Flow
[0149]
[0150] As with the previous embodiments, each stage in the present embodiment is configured to facilitate independent accessibility of the modular conditioning component (in the present example, a single-stage regulator) situated therein via adjacent access port or opening formed in the body, said stages configured for serial flow therethrough to a fourth, adjustable regulator stage, so as to provide four stages. The present exemplary application, as in the previous embodiments, is illustrated in the form of a multi-stage regulator configured to provide stepped-pressure reductions so as to avoid or diminish Joule-Thomson effect condensation of a wet gas sample, including passage to the first regulator stage, and passage from the third regulator stage to the fourth regulator stage, although this application is for illustrative purposes only and is not intended to be limiting.

[0152]
[0153]
[0154] Continuing with
[0155] The body 202 of device 201 has formed therein a longitudinal receiver 214 having first 215 and second 215 ends and an inner sidewall 215, the first end 215 of longitudinal receiver comprising a threaded 216 opening 216 in the base 207 formed to receive a threaded 224 insert 224 with o-ring 224 or the like to provide a sealed connection, the second end 215 terminating into a flow passage 217 leading to adjustable regulator 206.
[0156] The longitudinal receiver 214 is formed to receive, in stacked arrangement from the base, first 212, second 212, and third 212 stackable chamber components, respectively, each said stackable chamber components 212, 212, 212 having formed therein a modular component receivers or piston chamber 243, 243, 243, respectively, said receiver or chamber(s) positioned in said longitudinal receiver so as to be situated in a lateral 225 orientation relative to the longitudinal axis 208 of the body, when installed in said receiver 214.
[0157] Each said chamber component is situated in stacked form upon the other in said longitudinal receiver to facilitate insertion or removal therefrom as required. Upon placing or inserting 255 each chamber component 212, 212, 212 into the longitudinal receiver 214, it is important that the piston chamber 243, 243, 243 formed in each said chamber component be in alignment 223 with the respective access port 252, 252, 253. This can be accomplished by rotating 255 or axially adjusting each chamber component 212, 212, 212 respectively to the extent required to ensure that each respective piston chamber 243, 243, 243, is positioned to be in alignment 223 with its respective, adjacent access port 252, 252, 252, to ensure ready exterior access on demand to the respective piston chamber, and any modular conditioning component situated therein, via said respective access ports, the respective chamber components slidingly situated in stacked formation within the longitudinal receiver 214 and affixed in position, such as via orientation means, as further discussed herein, or manual alignment, and fixing said chamber components in place via tightening T insert 224, or other means, as discussed herein.
[0158] Each chamber component 212, 212, 212 has situated thereabout an o-ring 213, 213, 213 or similar sealing means to provide a fluid seal between each component to the inner sidewall 215 of said longitudinal receiver 214. In addition, each chamber component 212, 212, 212 has an o-ring 219, 219, 219 or similar seal provided between the stacked components, situated to envelope a fluid passage 222, 222 at opposing ends 213, 213 of said chamber components, and which are in alignment 223 upon stacking of same, for serial communication therethrough.
[0159] Piston chambers 243, 243, 243 formed in each chamber component 212, 212, 212, respectively are formed to receive one or more modular conditioning components (as will be more fully discussed herein), the overall (assembled) device 201 of the present exemplary embodiment shown as having a cylindrical outer surface 205 defining an outer diameter 205 with wrench flats 209, 209 formed in the upper 204 and lower 204 sections, respectively, to facilitate engagement (and tightening or loosening) via an open-ended wrench or the like.
[0160] Each access port 252, 252, 252 formed in the lower section 204 of said body 202 is threaded to provide a threaded opening 244, for receiving a threaded cover 245 formed to engage O-Ring 245 or other seal to provide a sealed chamber 242, each said chamber associated with said piston chambers, so as to receive a drop-in modular conditioning component (or piston) in the form of a modular regulator component 246, 246, 246 therein respectively, with each said each component 246, 246, 246 inserted 249 or otherwise placed in to their respective piston chamber 243, 243, 243, and sealed therein via threadingly engaging 227 a respective cover 245 with O-ring 245 to the threaded opening 244 of each the respective access port 252, 252, 252. While the present example shows the threaded cover 245 with o-ring 245 as separate and distinct from the modular conditioning component (shown as modular regulator components 246, 246, 246) it is noted that alternatively the threaded cover 245 can be formed integrally with the modular regulator component to provide a one-piece unit, and thereby simplify removal and replacement of said modular regulator component(s).
[0161] As discussed, in the present exemplary embodiment, each modular conditioning component comprises a regulator or pressure reducer, to provide staged pressure reduction of fluid flowing serially therethrough, so as to prevent Joule-Thompson condensation of wet gas (gas having entrained liquid therein), and provide pressure reduced wet gas for analytical testing or other application.
[0162] Continuing with the figures, a fluid inlet 228, which can comprise, for example, an NPT inlet connection 228, is provided at about the first end 203 of the lower section 204 of the body 202 to receive a flow of fluid 233 (wet gas or the like) therein to facilitate flow via passage 254 to the first chamber component 212 and associated modular conditioning component 246, where fluid therethrough is conditioned then flows to the second, third and fourth conditioning stages provided by the respective second and third modular conditioning components 246, 246, and adjustable regulator 250, as will be more fully discussed herein.
[0163] Unlike prior art systems, the unique modular features of the present invention, with the associated first, second and third piston chambers 243, 243, 243 respectively oriented n orientation to provide independent access means via a respective access port 252, 252, 252 for engagement with removeable cover 245, provides easy, individualized access to each chamber and associated modular conditioning component or piston, to allow for individual changes and/or maintenance as required, as opposed to having to require disassembly of the entire unit to change or repair an individual regulator stage, or replace O-ring seals as required on an individual basis as in various prior art systems.
[0164] In addition, one can simply access a drop-in modular conditioning component within the chamber, perform the desired operation (replace, reconfigure, service, remove, etc.) then by removing the treaded cover 145, then replace to seal the unit in place.
[0165] Following passage through the third piston chamber 243 and associated modular conditioning component, in this case, regulator component 246 (when used), the reduced fluid (having passed through the conditioning components) then flows through a sealed 229 (via o-ring) spacer component 229 via central flow through passage 229 to an adjustable regulator 250 for a final pressure reduction or regulation, said adjustable regulator 250 having the same components and operation as the adjustable regulator of the single-stage, first embodiment of the invention shown in
[0166] After passage through the final stage (the adjustable regulator 250), the pressure reduced fluid flows through passage 251 before it flows 252 out of the device via outlet 228.
[0167] As previously noted, the device of
[0168] Lastly,
[0169] As shown in the present embodiment, each modular chamber component 256, 256, 256 has a bottom or first end 261 and top or second end 261, with each said modular chamber component 256, 256, 256 having a side wall 266 having modular conditioning component receivers 267, 267, 267 (also referenced as piston chamber or piston chambers) formed therein, respectively. Further, spacer 258 has sidewall 270, a bottom or first 269 end and top or second 269 end.
[0170] In order to facilitate proper orientation of the modular conditioning components 256, 256, 256 and ensure they are properly situated in longitudinal receiver 259 so that said respective modular conditioning component receivers 267, 267, 267 are in alignment 270 with respect to access ports 271, 271, 271 formed in said body 264, respectively, so as to provide ready access via the outer surface 272 of said body 264, each of said modular chamber components 256, 256, 256 are formed to receive and interconnect in stacked form via alignment pins 273, 273, 273, respectively, each said pin having a length 274 and first 274 and second 274 ends.
[0171] To facilitate uniform alignment of the modular chamber component receivers 267, 267, 267 of modular chamber component 256, 256, 256 respectively in stacked form, alignment pins are provided between the stacked 268 components to fix said components in position relative to one another and facilitate alignment of same.
[0172] Particularly, alignment pin 273 is provided to engage stacked modular chamber components 256 and 256 via pin sockets 276, 276 formed in said modular chamber components, respectively, while alignment pin 273 is situated between stacked modular chamber components 256 and 256 via pin sockets 276, 276, respectively, formed in said modular chamber components. Further, alignment pin 273 is provided and situated between the top 261 of modular chamber component 256 and bottom 269 of spacer block 258 via pin sockets 277, 277 formed therein to engage same, respectively, the interconnected modular chamber components 256, 256 256 and spacer 258 via said alignment pins 273, 273,273 forming an interconnected stack 268, with modular chamber components 256, 256, 256 positioned in uniform, fixed alignment relative one another. Further, the top 269 of spacer block 258 has emanating therefrom alignment pin 279, with its first end 280, engaging pin socket 278 in top 269 of spacer block 258, and the second end 280 engaging pin socket 248 at the second end 265 of longitudinal receiver 259.
[0173] Said alignment pin 279 at the top of the stack 268 is positioned to engage the second end 265 of the longitudinal receiver 259 to ensure alignment of said stacked modular chamber components such that said respective modular conditioning component receivers 267, 267, 267 in said modular chamber components are in alignment 270 with respective access ports 271, 271, 271 of said body 24 when the stack 268 is placed into longitudinal receiver 259 of said body, so the second end 280 of said alignment pin 279 is inserted into said pin socket 248 formed in said body 264 at said second end 265 of said longitudinal receiver 259.
[0174] While the above embodiment illustrates as an example the use of pins to secure the modular chamber components in a fixed, uniform position relative to one another to ensure alignment of the modular component receivers with respective access ports as detailed above, further alternative means could be used to ensure said alignment. For example, a modular chamber component comprising a cylindrical sidewall configuration could include a rib formed to engage a groove in the sidewall of a cylindrical longitudinal receiver, the groove and rib positioned to ensure alignment of each piston chamber with its respective access port formed in the outer surface of the body of the device, to fix said cylindrical sidewall in a fixed position in said cylindrical longitudinal receiver, while allowing said modular chamber component to be slidingly positioned within said cylindrical longitudinal receiver.
