CAVITATION-RESISTANT LAMINATED DEPRESSURIZATION VALVE CAGE

WIPO Patent Application WO/2017/161940

A1

A cavitation-resistant laminated depressurization valve cage comprises a valve cage body (7) with a central through hole (8). An outer surface of the valve cage body is provided with multiple inlets. An inner surface of the central through hole is provided with multiple outlets. A depressurization channel (1) is disposed between the inlets and the outlets. The depressurization channel comprises dividing portions (101) and merging portions (102) that are connected in series and alternate. The dividing portion is used to change the direction of a liquid flow, while the merging portion is used to merge flows. Upon merging, the liquid flows collide with each other to generate a high turbulence, increasing friction between the flows as well as between the flows and a depressurization channel inner wall. Each time the flows merge, the flows collide with each other, canceling out a liquid impact force, thereby consuming flow energy and achieving depressurization.
