A valve assembly including a valve body defining an inlet, an outlet, a fluid flow path, and a chamber. A control element is disposed in the chamber and in the fluid flow path, and is rotatable by a valve stem about a pivot axis between an open position and a closed position. A flow conditioner coupled to the valve body and including a first end, a second end, and a plurality of channels extending between the first end and the second end. The plurality of channels are in flow communication with the fluid flow path of the valve body when the control element is in the open position. A plurality of walls separate the plurality of channels and include a first thickness and a second thickness different than the first thickness.

A throttling component and a conditioning and flowrate measurement device including a throttling component. The throttling component comprises a central throttling element and multiple peripheral throttling elements. The multiple peripheral throttling elements are sequentially sleeved on the exterior of the central throttling element, and are coaxial to the central throttling element; annular fluid channels are respectively formed between the central throttling element and its adjacent peripheral throttling element, and between adjacent peripheral throttling elements. A sensitive and clear differential pressure signal is generated while the throttling component stabilizes the flow, so that the accuracy and reliability of flowrate measurement can be improved.

A water processor is provided for processing or conditioning water to be distributed downstream of the water processor. The water processor includes a housing having an inlet and an outlet opposite the inlet. The water processor includes a conditioning element disposed inside of the housing between the inlet and outlet. The conditioning element includes a plurality of plates having apertures with sharp edges to direct the flow of water and facilitate splitting of small gas bubbles into even smaller nano-bubbles. The plurality of plates include a first plate having a first configuration of apertures and a second plate having a second configuration of apertures. The first and second plates are disposed in alternating spaced arrangement along the longitudinal axis of the housing. The second configuration is different from the first configuration such that the flow path through the water processor is circuitous or substantially indirect.

There is a valve assembly including a flow control valve and a flow centralizer. The flow centralizer has a flowthrough bore. The flow centralizer is downstream of the flow control valve and the flowthrough bore narrows in a direction downstream of the flow control valve. The flow centralizer may have a three-piece design including an insert defining the flowthrough bore and an orifice body and a flange ring which hold the insert in place within the orifice body.

An in-line ultrasonic attenuator (10) of this disclosure includes a longitudinally extending pipe (20) having a first and second end (21, 31), and a constant inside diameter extending an entire distance between the first and second ends. Instead of plates, the attenuator includes at least one helical baffle (23 or 33), or a first and a second helical baffle (23, 33) arranged in series with one another, coaxial to the longitudinal center line of the longitudinally extending pipe. The first helical baffle has a first twist rotation and the second helical baffle has a second twist rotation opposite that of the first twist, each twist rotation being at least 180°. The pipe ID can be the same as that connected to the ultrasonic gas flow meter. No elbows are required at the front or back end of a measurement skid of which the attenuator is a part.

A multi-pump pump system includes at least two pumps and a system pulsation dampener sized and configured to reduce a magnitude of pressure pulsations within a combined flow output by the at least two pumps, together with at least one mini-dampener coupled between the outlet of one of the pumps and header pipe(s) carrying flow from one of the pumps into the system pulsation dampener, the at least one mini-dampener sized and configured to reduce the magnitude of pressure pulsations over the system pulsation dampener alone. Optionally, a mini-dampener may be coupled between each pump and the system pulsation dampener. A single header pipe may carry combined flow from the at least two pumps into the system pulsation dampener, or separate header pipes may carry individual flows from the pumps into the system pulsation dampener.

A percussive pressure damper includes an entrance port, an exit port axially displaced from the entrance port, an axial flow channel extending from the entrance port to the exit port, a plurality of expansion chambers each extending radially from and in fluid communication with the axial flow channel, and an outer wall enclosing the axial flow channel and the expansion chambers. Each expansion chamber is enclosed by an inner surface of the outer wall and by interior walls, such that any cross section of the tube normal to the axial flow channel cuts through at least one interior wall between the axial flow channel and the outer wall. The expansion chambers may form a generally cylindrical honeycomb structure, each enclosing a hexagonal conical volume that expands in a radial direction, the expansion chambers axially stacked in radially symmetric and axially offset groups.

Implementations of an orifice plate configured to regulate a fluid flow are provided. An example orifice plate is configured to be positioned in a conduit and comprises a plurality of holes that extend through the orifice plate. The plurality of holes are arranged to form a criss-crossing pattern of spiral layouts configured to regulate a fluid flow passing therethrough. The number of clockwise spiral layouts is a Fibonacci number and the number of counter-clockwise spiral layouts is a Fibonacci number. In some implementations, each spiral layout is a logarithmic spiral. In some implementations, each hole of the plurality of holes is a contoured conical shape extending between an inlet and an outlet, the inlet is larger in diameter than the outlet.

Plates and plate assemblies for noise attenuators and other devices and methods of making the same are described herein. An example disc-shaped plate described herein includes a plurality of sector-shaped plates that have openings defining flow paths. Each of the plurality of sector-shaped plates has a first radial edge forming a first mating feature and a second radial edge forming a second mating feature that is complementary to the first mating feature such that, when the plurality of sector-shaped plates are arranged together, the first mating feature of each of the plurality of sector-shaped plates mates with the second mating feature of an adjacent one of the plurality of sector-shaped plates.

Example noise attenuators for use with process control devices are described herein. An example apparatus includes a first plate and a second plate disposed in a fluid passageway of a noise attenuator. The second plate is spaced apart from the first plate. The example apparatus also includes a first support rod extending along a central axis of the fluid passageway. The first support rod is coupled to the first plate and to the second plate. The example apparatus further includes a second support rod extending along an axis parallel to and offset from the central axis. The second support rod is coupled to the first plate and the second plate.
