氣動薄膜切(qiē)斷閥是采用頂(dǐng)導向結構，配用多彈簧(huáng)薄膜執(zhí)行機 構。閥體結(jié)構形式(shì)有(yǒu)單座、套筒、三通(tōng)等三種結構。具有結(jié)構緊 湊(còu)、重量輕(qīng)、動作靈敏、流體通道呈s流(liú)線型(xíng)、壓降(jiàng)損失小、閥(fá) 容量(liàng)大、拆(chāi)裝方(fāng)便等優點。該閥(fá)接收來自(zì)調節(jiē)儀表的信(xìn)号，切(qiē)斷、 開啟或改變介質(zhì)流(liú)向，達到對壓(yā)力(lì)、流(liú)量、溫(wēn)度或(huò)液位等工(gōng)藝參(cān) 數自動控制。廣泛應用于(yú)環保(bǎo)水處理、石油、化工、冶金、電(diàn)力、 輕工、紡(fǎng)織等(děng)各種(zhǒng)工(gōng)業部門(mén)的生(shēng)産過(guò)程自動控(kòng)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.
