氣動薄膜切斷(duàn)閥是(shì)采用頂(dǐng)導向結構，配用多(duō)彈簧薄膜執行機 構。閥體結構形式(shì)有單座、套筒、三通等三種結構。具有結構緊 湊、重量輕、動作(zuò)靈敏、流體通道呈S流(liú)線型、壓降損失小、閥 容量大、拆裝方便等優點。該閥(fá)接收來(lái)自調(diào)節儀表的信号，切(qiē)斷、 開啟或改變介質(zhì)流向，達到對壓力、流量(liàng)、溫度或液位等工藝參 數自(zì)動控制。廣(guǎng)泛應用于(yú)環保(bǎo)水處理、石油、化工、冶金、電(diàn)力、 輕工、紡織等(děng)各種(zhǒng)工業部門的生産(chǎn)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.
