切斷閥是自動(dòng)化系統(tǒng)中執(zhí)行機(jī)構(gòu)的一種，由多彈簧氣動(dòng)薄膜執(zhí)行機(jī)構(gòu)或浮動(dòng)式活塞執(zhí)行機(jī)構(gòu)與調(diào)節(jié)閥組成，接收調(diào)節(jié)儀表的信號(hào)，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(jiǎn)單，反應(yīng)靈敏，動(dòng)作可靠等特點(diǎn)?？?**地應(yīng)用在石油、化工、冶金等工業(yè)生產(chǎn)部門。氣動(dòng)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(diǎn)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(yùn)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(shí)，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，結(jié)果喪失了關(guān)閉件的密封性，在滲漏介質(zhì)對(duì)金屬的作用下，初始時(shí)的小漏很快會(huì)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(jí)和連接方式，必須同與其相連接的設(shè)備的規(guī)格相符。這一點(diǎn)適用于所有的切斷閥，無論它是直接安裝在設(shè)備上還是裝在一個(gè)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(shí)。帶手動(dòng)裝置，可以實(shí)現(xiàn)超速、油壓低（氣壓低）自動(dòng)停車系統(tǒng)。康明斯CUMMINS柴油機(jī)進(jìn)氣切斷閥兼容AMOT</p><p
