氣動薄膜切斷閥是采用頂(dǐng)導向結構(gòu)，配用(yòng)多彈簧薄(báo)膜執(zhí)行機 構。閥體結構形式有單座(zuò)、套筒、三通(tōng)等三種結構。具有結構緊 湊、重量輕、動作靈敏、流體通道呈S流(liú)線型、壓降損失小、閥 容(róng)量大、拆裝方便等優點。該閥接收來(lái)自調節儀表的信号，切斷、 開啟或改變介質流向，達到對壓(yā)力、流量、溫度或液位等工(gōng)藝參 數自(zì)動控制。廣泛應用于環保水處理、石油、化工、冶金、電(diàn)力、 輕工、紡織等(děng)各種工業部門的生産過程自(zì)動控制和遠程控制系統 中。 

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.
