Disclosed is a water piping system. More particularly, the present invention relates to a water piping system having a function to dampen the effects of water hammer and check valve slam at a sudden stoppage of a pump and relates to a tank connector therefor, in which the water piping system ejects a high pressure jet stream from a high pressure tank in the direction of a primary flow in a main pipeline, thereby deterring the backflow of pipeline water in the main pipeline and reducing the pressure of pipeline water against a check valve, which enables the check valve to be slowly closed.

A flow conditioner comprising a perforated plate with a central hole and four or more circular paths, which are arranged radially from the central hole and concentrically with one another, wherein holes are arranged on these concentric circular paths, characterized in that a preponderate number of holes of an intermediate circular path have a greater hole diameter than a preponderate number of holes of the innermost and a preponderate number of holes of the outermost circular paths.

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 flow restriction device and/or a sanitary shower equipped with the flow restriction device includes a restrictor body composed of multiple web planes disposed successively in an axial direction and filling a passage cross-section of the restrictor body perpendicular to the axial direction. Each web plane is composed of a plurality of webs extending mutually in parallel and perpendicular to the axial direction, spaced from each other thereby leaving web intermediate gaps. Webs of two directly adjoining web planes extend non-parallel to each other. The device is useful in overhead showers, for example, and limits noise.

A method includes assembling a silencer baffle configured to mount in a fluid conduit along a fluid flow path, where assembling the silencer baffle includes coupling together a plurality of baffle sections via mating interlock structures.

A fluid regulating device includes a valve having an inlet and an outlet and an actuator coupled to the valve and having a control assembly. The control assembly includes a control element and a diaphragm operably connected to the control element, the control element disposed within the valve and adapted to be displaced relative to a valve seat. A noise attenuation assembly is coupled to the outlet of the valve and includes a cylindrical body and at least one plate disposed in the cylindrical body, the at least one plate having an outer edge. An apparatus for retaining the noise attenuation assembly includes a plurality of rods coupled to the at least one plate. The plurality of rods includes at least one rod having a first end disposed through the outer edge of the at least one plate to support the noise attenuation assembly.

Noise attenuation apparatus for fluid devices are disclosed herein. A noise attenuation apparatus includes a first plate having a plurality of first openings to reduce noise generated by a fluid flowing through a fluid device and a second plate having a plurality of second openings to reduce noise generated by the fluid. The second plate directly engages the first plate, and the first openings to at least partially align with the second openings when the first plate is in direct engagement with the second plate to define a flow passageway of the noise attenuation apparatus.

A flow control device that includes an orifice placed in an opening of a duct. A flexible sheet of material is wrapped around a first duct section to include an extended section which is crimped inwardly around the face of the orifice. A sleeve with tightening straps can be wrapped around the aligned first and second duct sections, with the sections having the orifice positioned between. A bead on the duct sections can assist in orifice positioning, attachment, and sealing. The orifice can also be attached to the duct section using tabs and a retention ring. A duct sleeve is also provided for placement in the opening of a duct. The duct sleeve includes a reception slot that receives an orifice plate that is attached in a secure and sealable manner.

A pipe joint has a tube for fluid detachably fitted thereto, and is connected to a hydraulic device such as a cylinder. The pipe joint is provided with a resin body into which the tube for fluid is inserted, and a metal body which can rotate relative to the resin body. The resin body comprises orifices which each have a different opening diameter, and, as a result of the rotation of the resin body relative to the metal body, the orifices can be disposed in a connection part providing a connection path between the tube for fluid and the hydraulic device.
