美国FAIRCHILD调节阀江苏办事处*

FAIRCHILD减压阀的作用原理是靠阀内流道对水流的局部阻力降低水压，水压降的范围由连接阀瓣的薄膜或活塞两侧的进出口水压差自动调节。定比减压原理是利用阀体中浮动活塞的水压比控制，进出口端减压比与进出口侧活塞面积比成反比。这种减压阀工作平稳无振动；阀体内无弹簧，故无弹簧锈蚀、金属疲劳失效之虑；密封性能良好不渗漏，因而既减动压（水流动时）又减静压（流量为0时）；特别是在减压的同时不影响水流量。

美国FAIRCHILD减压阀是气动调节阀的一个*配件，主要作用是将气源的压力减压并稳定到一个定值，以便于调节阀能够获得稳定的气源动力用于调节控制。按结构形式可分为薄膜式、弹簧薄膜式、活塞式、杠杆式和波纹管式；按阀座数目可人为单座式和双座式；按阀瓣的位置不同可分为正作用式和反作用式。
