氣(qi)動薄膜切斷閥是(shi)采用頂導向結構(gòu)，配用多彈簧薄膜(mo)執🔴行機 構。閥體結(jié)構形式有單座、套(tao)筒、三通等🔴三種結(jié)構。具有結構緊 湊(còu)、重量輕、動作靈敏(min)、流體通道呈S流🔞線(xiàn)型、壓💁降損失小、閥(fá) 容量大、拆裝方便(bian)等優點。該閥接收(shou)來自調節儀表的(de)信号，切斷、 開啟或(huo)改變介質流向，達(dá)到對壓力、流量、溫(wen)度或液位等工藝(yi)參 數自動控制。廣(guǎng)泛應用于環保水(shui)處理、石油、化工、冶(yě)金、電力、 輕工、紡織(zhi)等各‼️種工業部門(mén)的生産過程自動(dong)控制和遠程控⭐制(zhì)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.
