smc气动服务@SMC内部先导式减压阀

于先导活塞式减压阀。由主阀和导阀两部分组成。主阀主要由阀座、主阀盘、活塞、弹簧等零件组成。导阀主要由阀座、阀瓣、膜片、弹簧、调节弹簧等零件组成。通过调节调节弹簧压力设定出口压力、利用膜片传感出口压力变化，通过导阀启闭驱动活塞调节主阀节流部位过流面积的大小，实现减压稳压功能。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。这些阀门应该针对有用控制范围选择，即大流量的20%到80%。正常为等比型或者具有等比特性。这些类型的阀门本身具有比例控制所要求的佳流量特性及流量范围。
SMC减压阀，SMC进口先导式减压阀是采用控制阀体内的启闭件的开度来调节介质的流量，将介质的压力降低，同时借助阀后压力的作用调节启闭件的开度，使阀后压力保持在一定范围内，在进口压力不断变化的情况下，保持出口压力在设定的范围内，保护其后的生活生产器具。本类阀门在管道中一般应当水平安装。

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。

减压阀是一种利用介质自身能量来调节与控制管路压力的智能型阀门。用于生活给水、消防给水及其他工业给水系统通过调节阀减压导阀即可调节主阀的出口压力。出口压力不因进口压力、进口流量的变化而变化，安全可靠地将出口压力维持在设定植上，并可根据需要调节设定值达到减压的目的。该阀减压，性能稳定、安全可靠、安装调节方便，使用寿命长。 减压阀是一种自动降低管路工作压力的专门装置，它可将阀前管路较高的水压减少至阀后管路所需的水平。减压阀广泛用于高层建筑、城市给水管网水压过高的区域、矿井及其他场合，以保证给水系统中各用水点获得适当的服务水压和流量。
