气动隔膜阀专用于控制非腐蚀性或一般腐蚀性介质,阀体内腔表面无衬里或覆有可供选择的各种橡胶,适用于不同工作温度和流体管路。气动隔膜 阀的工作原理浅谈如下:
气动隔膜阀的关闭与开启是通过来自管路的压力作用于增强橡胶隔膜实现的。当压力介质进入阀门控制腔,隔膜下压,关闭阀门通道,当控制 腔压力排向大气或下游管道,隔膜上升,阀门通道被打开。阀门没有阀杆、密封垫、定向座等,通道中运动的唯一部件就是隔膜,所以不存在锈蚀 及抱死现象,具有更高的稳定性。多种结构形式及控制形式,可适用于多种的流体控制需要。

译文:
Pneumatic diaphragm valve is designed to control non corrosive or corrosive media, the body cavity surface unlined or covered with all kinds of rubber alternative, suitable for different temperature and fluid pipeline. Working principle of pneumatic diaphragm valve is as follows:
Gas and open the pneumatic diaphragm valve is closed by the pipeline pressure on the septa velum clique. When the pressure go into the valve control chamber, the diaphragm down, close the valve channel, the diaphragm up when the pressure of the control cavity emission to the atmosphere or downstream pipeline, the valve is opened, the channel. No valve stem, sealing gasket, orientation seat, is the only component channel movement of the diaphragm, so there is no rust and locking phenomenon, has higher stability. A variety of structure and control mode, need to fluid control can be applied to a variety of.气动隔膜阀工作原 理。
