切斷閥是自動化系統(tǒng)中執(zhí)行機構(gòu)的一種，由多彈簧氣動薄膜執(zhí)行機構(gòu)或浮動式活塞執(zhí)行機構(gòu)與調(diào)節(jié)閥組成，接收調(diào)節(jié)儀表的信號，控制工藝管道內(nèi)流體的切斷、接通或切換。具有結(jié)構(gòu)簡單，反應(yīng)靈敏，動作可靠等特點?？?**地應(yīng)用在石油、化工、冶金等工業(yè)生產(chǎn)部門。氣動切斷閥的氣源要求經(jīng)過濾的壓縮空氣，流經(jīng)閥體內(nèi)的介質(zhì)應(yīng)該是無雜質(zhì)和無顆粒的液體和氣體。根據(jù)允許壓差情況、介質(zhì)特點以及工藝管道要求，可選用單座、套筒、三通切斷閥。切斷閥工作的可靠性，在很大程度上取決于正確選擇其結(jié)構(gòu)和完全能適合其工作條件的材料，并取決于運行條件。如切斷閥只能在兩種狀態(tài)下工作，全開或全關(guān)。當(dāng)閥瓣在閥座內(nèi)處于中間位置時，由于壓降大而產(chǎn)生大的流速，這就形成汽蝕的條件，引起侵蝕，破壞閥瓣和閥座的密封面，濟柴發(fā)電機組進氣切斷閥配置豐富，結(jié)果喪失了關(guān)閉件的密封性，在滲漏介質(zhì)對金屬的作用下，初始時的小漏很快會變成大漏。折疊編輯本段材質(zhì)所有切斷閥的材質(zhì)、壓力等級和連接方式，濟柴發(fā)電機組進氣切斷閥配置豐富，必須同與其相連接的設(shè)備的規(guī)格相符。這一點適用于所有的切斷閥，濟柴發(fā)電機組進氣切斷閥配置豐富，無論它是直接安裝在設(shè)備上還是裝在一個與設(shè)備相連的立管上。折疊編輯本段位置和尺寸切斷閥可裝在容器接頭或立管上。當(dāng)閥連接在立管上時。三通電磁閥用切斷信號驅(qū)動氣壓來切斷進氣切斷閥。濟柴發(fā)電機組進氣切斷閥配置豐富</p><div
