氣動薄膜切斷閥是[Shi]采用頂[Ding]導向結構，配用多彈簧薄膜執[Zhi]行機 構。閥體結構形(Xing)式(Shi)有單座、套筒、三(San)通等三(San)種結構。具有(You)結(Jie)構緊 湊、重量輕[Qing]、動作靈敏、流體通道呈S流(Liu)線型(Xing)、壓降損失小、閥(Fa) 容量大、拆裝方(Fang)便等[Deng]優點。該閥接收來自調節儀表的信号，切[Qie]斷、 開啟[Qi]或改變介[Jie]質流向，達到對壓力、流[Liu]量、溫度或液位等工藝參 數自動控制。廣泛(Fan)應用于[Yu]環保[Bao]水處(Chu)理、石(Shi)油[You]、化工、冶金、電力、 輕工、紡織[Zhi]等各種工業部門(Men)的生産過(Guo)程自(Zi)動控制和(He)遠程(Cheng)控制系統 中[Zhong]。 

The pneumatic diaphragm cut-off valve is subject to a top guide structure with multi spring diaphragm actuator.There are three types of valve body structure：single seat， sleeve and three-way.It has the advantages of compact structure， lightweight， sensi tv e action， S streamlined fluid passage， small pressure drop loss， large valve capacity， convenient disassembly and assembly， etc.The valve receives the signal from the regulating instrument， cuts off， opens or changes the flow direction of the fluid to achieve the automatic control of the process parameters such as pressure， flow， temperature or liquid level.It is widely used in the automatic control and remotecontrol system of production process of environmental protection water treatment， petroleum， chemical industry， metallurgy， electric power， light industry， textile and other industrial sectors.
