摘要： A flow resistance insert of a flow rate measuring or flow rate control has contiguous discs between which at least one central axial flow duct is formed from which radial flow ducts branch off. The discs include alternating first discs and second discs. While the first discs are circumferentially closed ring discs, the second discs are circumferentially slotted one-piece ring discs.

摘要： 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.

摘要： 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.

摘要： A bypass line is described that is capable of equalizing pressure within an HVAC system. The bypass line can also cause less noise than other solutions. A bypass line under the present disclosure can comprise a line from a high pressure side to a low pressure side of an HVAC system. Valves and orifices can be disposed within the bypass line. The valves and orifices help to slow the speed of fluid from high pressure to low pressure locations, thus reducing noise during pressure equalization.

摘要： A first ring and a second ring are inserted through the pipe. The pipe is inserted through a fastening member, and a tip of the pipe is inserted into a first concave part of the joint. By screwing a screw part of the fastening member to a screw part of the joint, the first ring and the second ring are pressed against the first contact surface provided to the first concave part, and bite into the pipe to fix the pipe. Further, the pipe fixed by the first ring and the second ring is moved to a joint side by a pressing force to press an orifice plate installed in the joint. Consequently, it is possible to maintain sealability of a flow path in the joint at a plurality of places including a place of the orifice plate.

摘要： The valve includes a valve body that inwardly defines a passage for circulation of a fluid, a drive shaft, and a bearing to guide the rotation of the drive shaft. The bearing comprises a chamber surrounding a segment of the drive shaft and a plurality of balls filling the chamber. The balls are free inside the chamber, and the chamber is completely filled with balls. The balls are in contact with the drive shaft along all or part of the segment.

摘要： An aspect of the present disclosure includes a multi-stage compressor having a low pressure compressor stage and a high pressure compressor stage operable for compressing a working fluid. An integrated device including a heat exchanger directly connected to a combination unit is operable for reducing pressure pulsations, cooling and separating moisture in a first compressed flow stream and a second compressed flow stream discharged from the low pressure stage and the high pressure stage respectively. A first pressure pulsation dampener, a first moisture separator, a second pressure pulsation dampener and a second moisture separator are integrally formed within the combination unit.

摘要： Apparatus and systems for mitigating erosion in flow conduits, and may include a housing including a fluid inlet and a fluid outlet and a flow path there between. A movable or static (passive) insert is disposed within the housing and may be configured to alter a flow of a fluid passing from the fluid inlet to the fluid outlet. The apparatus may also include a mechanism to adjust a position of the movable insert.

摘要： A regulator for clutch actuator includes a housing having a cylindrical damping space inside, a first fluid path interconnecting the damping space and a master cylinder, and a second fluid path interconnecting the damping space and a an operating cylinder. The regulator further includes a flexible valve member contained in the damping space for reducing vibrations. The flexible valve member comprises a first inflow guiding portion configured to receive and guide fluid from the first fluid path. The first inflow guiding portion has a plurality of through holes such that elastic deformation of the first inflow guiding portion reduces vibration when fluid flow into the cylindrical damping space from the master cylinder.
