摘要
介绍了一种迷宫式多级降压结构调节阀能够降低进液流速和压力,避免了对金属密封面的冲刷和磨损,延长了阀门的使用寿命。阀芯和阀杆采用一体式结构,解决了压力波动产生的阀芯振动问题。
Introduces a labyrinth structure of multi-stage decompression valve to reduce into the fluid flow rate and pressure,avoided to metal seal face wash and wear,prolong the service life of the valve.Valve core and valve stem adopts one-piece structure,solve the problem of the valve core vibration produced by the pressure fluctuation.
