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廣泛應(yīng)用，在氣體泄漏、意外事故、操作不當(dāng)、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。氣動薄膜切斷閥氣動切斷閥結(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。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比較好選擇，當(dāng)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！氣動切斷閥在無氣壓情況下。河北柴油發(fā)電機組進氣切斷閥E系列切斷閥E-F/E-FM系列。</p><div
