切斷閥(Cutoffvalve)又稱緊急切斷閥，顧名思義，用以緊急時切斷流體的安全閥門，切斷閥有：氣動緊急切斷閥液動緊急切斷閥燃氣緊急切斷閥液氨緊急切斷閥。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?？善毡榈貞?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。切斷閥采用安全閥的升降結(jié)構(gòu)和止回閥防止介質(zhì)倒流的原理，內(nèi)結(jié)構(gòu)裝有低熔點(易熔合金)的塞子。在外界≥80C溫度(易熔金)熔化，堵塞氣管泄壓。切斷閥迅速關(guān)閉，保護貯罐系統(tǒng)的安全。切斷閥專為液氨、氨氣、燃氣的管路或裝置設(shè)計。填料采用聚四氟乙烯，密封可靠、***物外漏。密封副材料采用聚四氟乙烯或尼龍對閥體本體材料，為軟密封，密封可靠。加上防爆電磁閥，空氣減壓過濾器，信號反饋開關(guān)，能夠遠距離的控制閥門，為生產(chǎn)工作提高了安全、方便、快捷的效率。</p><p> 其密封效果不很理想。這類閥的泄漏率通常為10-4，經(jīng)精密研磨后可達到10-6，可達較高的密封等級。球面密封利用球面的球面轉(zhuǎn)動與固定的閥定小錐面相切，它們之間為線接觸，這就比上述面對面密封效果好。球閥、球面密封蝶閥等就是采用這一思路來制作的，其泄漏率可達10-6~10-8，高性能的三偏心蝶閥可達10-8，甚至為零泄漏。折疊密封類型軟密封除耐腐蝕的襯里閥門外，一般的軟密封閥指閥芯或閥座兩者之一采用非金屬材料(主要為聚四氟乙烯和橡膠等)的密封形式的閥。軟密封閥密封效果**佳，但在管道安裝、系統(tǒng)的清洗中都有可能留下或多或少不干凈的雜物(如焊渣、鐵屑等)，它們流經(jīng)調(diào)節(jié)閥時，容易把軟密封閥座或閥芯劃傷，使泄漏量增加，密封可靠性差。所以，選擇軟密封結(jié)構(gòu)必須考慮介質(zhì)的清潔和投運前嚴格沖洗管道。硬密封硬密封再堆焊耐磨合金是切斷閥的**佳選擇。這種方式在考慮密封性的同時也考慮了使用壽命和可靠性，雖然出廠指標只有10-4~10-5，達不到軟密封零泄漏的效果，但足以滿足嚴密切斷的要求，而且它經(jīng)久耐用，從經(jīng)濟的角度考慮更合算。此外還需要注意以下兩點:1)對密封可靠性的考慮:軟密封，切斷效果好，但不適宜用于顆粒介質(zhì)，一旦劃傷，泄漏會急劇增加。因此。E系列切斷閥E-T系列。</p><div

進口氣動切斷閥工作原理圖及結(jié)構(gòu)特點進口氣動切斷閥是用于工藝管道中突發(fā)故障或事故時，將管路介質(zhì)（液體、氣體）流體緊急快速截斷的高性能切斷閥，具有動作迅速、嚴密切斷、安全可靠等特點，在其高危險物料的加工處理，貯存運輸過程中被得到普遍應(yīng)用，在氣體泄漏、意外事故、操作不當、人員沒辦法靠近時，能夠遠距離快速關(guān)閉閥門，起安全保護作用。進口氣動切斷閥結(jié)構(gòu)特點：1、切斷閥采用薄膜式多彈簧執(zhí)行機構(gòu)與調(diào)節(jié)機構(gòu)用三根立柱相連，整個高度可減小約30％，重量可減輕約30％。2、閥體按流體力學(xué)原理設(shè)計成等截面低流阻流道，額定流量系數(shù)增大30％。3、閥內(nèi)件密封部分有嚴密型和軟密封兩種，嚴密型為堆焊硬質(zhì)合金，軟密封型為軟質(zhì)材料制作，關(guān)閉時密封性能優(yōu)良。4、平衡型閥內(nèi)件，提高了切斷閥的許用壓差。進口氣動切斷閥工作原***動切斷閥主要由執(zhí)行機構(gòu)與閥體兩部分組成，通常由控制室/控制中心操作，也可以在現(xiàn)場安全地操作。氣動切斷閥對閥的基本要求是：關(guān)閉嚴密快速，并具火災(zāi)安全結(jié)構(gòu)。雖然，常規(guī)閥門中，高密封性能的金屬密封是較佳選擇，當采用軟密封結(jié)構(gòu)時，必須是火災(zāi)安全型結(jié)構(gòu)，以保證軟密封結(jié)構(gòu)失效后，仍能截斷危險物料而不流入事故場所！E系列切斷閥E-M系列。貴州進氣切斷閥</p><p
