摘要： A valve trim for a pressure reduction valve containing a plurality of high hydraulic flow resistance flowpaths therethrough. Each flowpath comprises at least two inlets (208, 209) and at least one impingement zone (210) having two zone inlets (211, 212) and two zone outlets (213, 214). The zone inlets (211, 212) communicate with the inlets (208, 209) and are arranged substantially 180 degrees to one another. The two zone outlets (213, 214) are arranged substantially perpendicular to the zone inlets (211, 212) such that flow entering the two zone inlets (211, 212) mutually impinges on itself creating an area of high energy loss, and thereafter separates and exits through the zone outlets (213, 214).

摘要： A laminar flow tool is for channeling water, air or other fluids through a down drill pipe or tubing for pressurization of other tools or other purposes. The tool provides a flow divider having an 180 degree twist separating a driven fluid chamber from a buffer fluid pocket. Fluid in the tool is calmed as it travels and loses some of the spin (“turbulence”) inherent in the water or other fluid. A buffer pocket on one side absorbs shocks and stabilizes the driven side. Ports in the buffer side help equalize pressure.

摘要： A pipeline for the transport of a pressurized flowable medium, consisting of a metal tube corrugated transversely to its longitudinal direction and of a hose which is arranged in the same and consists of plastic. In the position of use the hose bears against the inwardly pointing wave troughs of the metal tube, which hose has a multiplicity of holes separated from one another in the wall of the same over its entire axial length. The wave troughs of the metal tube penetrate slightly into the surface of the hose so as to fix the latter with respect to axial loads.

摘要： The present invention provides a silencer, which is coupled to a pneumatic device to reduce noise. The silencer (10) of the present invention has a double pipe structure, which includes an inner casing (11), which is coupled to an outlet of the pneumatic device, and an outer casing (12), which is coaxially provided around the inner casing (11). A space (18) is defined between the inner casing and the outer casing. The space communicates with an air guide hole (15), which is formed in one end of the inner casing.Furthermore, an acoustical absorbent (22) is provided in the space (18). Preferably, the acoustical absorbent has a spiral shape. Thus, compressed air, which has passed through the pneumatic device, passes through the acoustical absorbent of the silencer. At this time, almost all noise is absorbed by the acoustical absorbent.

摘要： A liner system for a steam outlet pipe of a turbine bypass system comprises a liner mounted in spaced coaxial relation to the inner pipe wall such that an annular cavity is defined between the liner and the steam outlet pipe. The cavity is open on an upstream end and closed on a downstream end such that a quarter-wavelength resonator is formed for attenuating noise associated with a flow of superheated steam passing through the steam pipe. The liner may include a plurality of perforations to further attenuate noise in the steam outlet pipe. The open upstream end and closed downstream end of the cavity increases pressure within the cavity to prevent cooling water from entering the perforations and contacting the inner pipe wall. A wire mesh disposed against the outer liner wall may block cooling water penetration through the perforations and may further attenuate noise associated with the flow of superheated steam.
摘要翻译：用于涡轮旁路系统的蒸汽出口管的衬套系统包括衬套，其以与内管壁间隔的同轴关系安装，使得在衬套和蒸汽出口管之间限定环形空腔。空腔在上游端打开并在下游端封闭，使得形成四分之一波长的谐振器用于衰减与通过蒸汽管的过热蒸汽的流动相关联的噪声。衬套可以包括多个穿孔，以进一步减弱蒸汽出口管中的噪音。空腔的开放的上游端和闭合的下游端增加腔内的压力，以防止冷却水进入穿孔并接触内管壁。设置在外衬套壁上的金属丝网可阻止冷却水穿透穿孔，并可进一步减弱与过热蒸汽流相关的噪音。

摘要： High energy loss fluid control is attained by subdividing flow of high pressure fluid into a plurality of individual streams in respective passageways having a long length to diameter ratio to impart high frictional resistance losses to the fluid flow, the passageways being in and between laminar surfaces and configurated along their lengths. For extremely high efficiency the passageways are in labyrinth formation.
