smc膜片式减压阀@SMC一级代理　　
SMC先导式减压阀按结构形式可分为膜片式、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。自力式减压阀的工作由阀后压力进行控制。当压力感应器检测到阀门压力指示升高时，减压阀阀门开度减小；当检测到减压阀后压力减小，减压阀阀门开度增大，以满足控制要求。先导式减压阀——该阀门的减压比必须在一定程度上高于系统值； 即使在大或者小流量时它也应该能够对正作用或者反作用控制信号做出响应。

smc膜片式减压阀将手轮外拉，见到黄色圈后，顺时针旋转手轮，调压弹簧被压缩，推动膜片组件下移，通过阀杆，打开阀芯，则进气口压力经阀芯节流降压，有压力输出。出口压力气体经反馈管浸入膜片下腔，在膜片上产生一个向上的推力。当此推力与调压弹簧平衡时，出口压力便稳定在一定值。

逆时针旋转手轮，调压弹簧力不断减小，阀芯逐渐关闭，膜片下腔中的压缩空气，经溢流阀不断从排气孔排处，直至后出口压力降为零。

调压完成后，将手轮压回，手轮被锁住，以保持设定压力一定。故称为锁定型手轮。

溢流式减压阀常用于二次侧负载变动的场合，如进行频繁调整的场合、二次侧有容器（如气缸）的场合。在使用过程中，经常要从溢流孔排出少量气体。当介质为有害气体的气路中，为防止污染工作场所，应选用无溢流孔的减压阀，即非溢流式减压阀。非溢流式减压阀也常用于经常耗气的吹气系统和气马达。
