氣(qi)動切斷(duan)閥(fa)(fa)(fa)不是(shi)調(diao)節(jie)(jie)閥(fa)(fa)(fa)門，它的(de)(de)功(gong)能是(shi)打開導通，關閉切斷(duan)，由(you)電磁(ci)閥(fa)(fa)(fa)控(kong)制(zhi)。因此，氣(qi)動切斷(duan)閥(fa)(fa)(fa)必定是(shi)與電磁(ci)閥(fa)(fa)(fa)配套，并且是(shi)由(you)電磁(ci)閥(fa)(fa)(fa)控(kong)制(zhi)。氣(qi)動調(diao)節(jie)(jie)閥(fa)(fa)(fa)才(cai)是(shi)調(diao)節(jie)(jie)閥(fa)(fa)(fa)門的(de)(de)，不僅(jin)可以開或關，閥(fa)(fa)(fa)門的(de)(de)任何開度都可以得到(dao)控(kong)制(zhi)。

氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)切(qie)(qie)(qie)斷(duan)(duan)(duan)閥(fa)(fa)(fa)不(bu)是(shi)調(diao)(diao)節閥(fa)(fa)(fa)門的(de)(de)(de)，它(ta)的(de)(de)(de)功能(neng)是(shi)打開(kai)導(dao)通(tong)，關閉切(qie)(qie)(qie)斷(duan)(duan)(duan)，它(ta)是(shi)由(you)電(dian)磁閥(fa)(fa)(fa)控(kong)(kong)制(zhi)(zhi)。因(yin)此，氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)切(qie)(qie)(qie)斷(duan)(duan)(duan)閥(fa)(fa)(fa)必(bi)定是(shi)與電(dian)磁閥(fa)(fa)(fa)配套，并且(qie)是(shi)由(you)電(dian)磁閥(fa)(fa)(fa)控(kong)(kong)制(zhi)(zhi)。氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)調(diao)(diao)節閥(fa)(fa)(fa)才是(shi)調(diao)(diao)節閥(fa)(fa)(fa)門的(de)(de)(de)，不(bu)僅可以(yi)開(kai)或關，閥(fa)(fa)(fa)門的(de)(de)(de)任何開(kai)度都可以(yi)得到控(kong)(kong)制(zhi)(zhi)。氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)切(qie)(qie)(qie)斷(duan)(duan)(duan)閥(fa)(fa)(fa)又稱氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)截(jie)止(zhi)閥(fa)(fa)(fa)，其是(shi)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)化(hua)系(xi)統中執行機構(gou)(gou)(gou)的(de)(de)(de)一種，由(you)多彈(dan)簧氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)薄(bo)膜(mo)執行機構(gou)(gou)(gou)或浮動(dong)(dong)(dong)(dong)(dong)(dong)(dong)式(shi)(shi)活塞執行機構(gou)(gou)(gou)與調(diao)(diao)節閥(fa)(fa)(fa)組成，接收調(diao)(diao)節儀(yi)表的(de)(de)(de)信號，控(kong)(kong)制(zhi)(zhi)工藝管(guan)道內流(liu)體(ti)(ti)的(de)(de)(de)切(qie)(qie)(qie)斷(duan)(duan)(duan)、接通(tong)或切(qie)(qie)(qie)換。具有結(jie)構(gou)(gou)(gou)簡單，反應(ying)靈敏，動(dong)(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)可靠等(deng)特點。可廣泛地(di)應(ying)用(yong)(yong)在石油、化(hua)工、冶(ye)(ye)金(jin)等(deng)工業(ye)生產部門。氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)切(qie)(qie)(qie)斷(duan)(duan)(duan)閥(fa)(fa)(fa)的(de)(de)(de)氣(qi)(qi)(qi)源要求(qiu)經過濾的(de)(de)(de)壓(ya)縮空氣(qi)(qi)(qi)，流(liu)經閥(fa)(fa)(fa)體(ti)(ti)內的(de)(de)(de)介質應(ying)該是(shi)無(wu)雜質和無(wu)顆粒(li)的(de)(de)(de)液體(ti)(ti)和氣(qi)(qi)(qi)體(ti)(ti)。氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)切(qie)(qie)(qie)斷(duan)(duan)(duan)閥(fa)(fa)(fa)采(cai)用(yong)(yong)軟密封(feng)(feng)結(jie)構(gou)(gou)(gou)，設計(ji)有工作(zuo)(zuo)密封(feng)(feng)和檢修密封(feng)(feng)，操作(zuo)(zuo)力矩小，密封(feng)(feng)比壓(ya)適(shi)中，密封(feng)(feng)可靠，動(dong)(dong)(dong)(dong)(dong)(dong)(dong)作(zuo)(zuo)靈敏，液動(dong)(dong)(dong)(dong)(dong)(dong)(dong)控(kong)(kong)制(zhi)(zhi)易(yi)于實現自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)控(kong)(kong)制(zhi)(zhi)，使用(yong)(yong)壽命長。切(qie)(qie)(qie)斷(duan)(duan)(duan)氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)球(qiu)閥(fa)(fa)(fa)廣泛使用(yong)(yong)于石油、化(hua)工、冶(ye)(ye)金(jin)、造紙、制(zhi)(zhi)藥、電(dian)鍍等(deng)行業(ye)。氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)切(qie)(qie)(qie)斷(duan)(duan)(duan)閥(fa)(fa)(fa)采(cai)用(yong)(yong)新型(xing)系(xi)列(lie)GT型(xing)、AT型(xing)氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)執行器，有雙作(zuo)(zuo)用(yong)(yong)式(shi)(shi)和單作(zuo)(zuo)用(yong)(yong)式(shi)(shi)（彈(dan)簧復(fu)位），齒輪齒條傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)，安全可靠，大口(kou)徑閥(fa)(fa)(fa)門采(cai)用(yong)(yong)系(xi)列(lie)AW型(xing)氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)執行器拔叉式(shi)(shi)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)，結(jie)構(gou)(gou)(gou)合理(li)，輸出扭矩大，有雙作(zuo)(zuo)用(yong)(yong)式(shi)(shi)和單作(zuo)(zuo)用(yong)(yong)式(shi)(shi)。
