氣動薄膜切(qiē)斷閥是采用(yong)頂導向結構(gou)，配用多彈簧(huang)薄膜執行機(jī) 構。閥體結構(gou)形式有單座(zuo)、套筒、三通等(děng)🔞三種結構。具(ju)有結構♌緊 湊(còu)、重量輕、動作(zuò)靈敏、流體通(tōng)道呈S流線型(xíng)、壓降損失小(xiǎo)、閥 容💃量大、拆(chāi)裝方便等優(you)😄點。該閥接收(shōu)來自調節儀(yi)表的🔞信号，切(qie)斷、 開啟或改(gǎi)變介質流向(xiang)，達到對壓力(li)、流量、溫度或(huò)液位等工藝(yi)參 數自動控(kong)制。廣泛應用(yòng)于環保水處(chu)理、石油、化工(gōng)、冶金、電力、 輕(qīng)工、紡🌐織等各(gè)種工業部門(men)的生産過程(chéng)自動控制和(he)遠程控制系(xi)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.
