style="text-indent:25px">氣動(dòng)式緊急切斷閥主要應(yīng)用于液化石油氣、液氨等氣、液相介質(zhì)的儲(chǔ)罐站管路和化工管道上，其工作原理和液壓式緊急切斷閥相近，結(jié)構(gòu)形式類似于截止閥故在一些場(chǎng)合也常常作為氣動(dòng)截止閥來使用，進(jìn)行作業(yè)時(shí)利用空氣壓縮機(jī)或者儲(chǔ)氣罐開啟主閥，在緊急情況時(shí)作業(yè)人員通過遠(yuǎn)距離快速泄放氣源，或者通過本體自帶的易熔元件進(jìn)***壓泄放進(jìn)行快速切斷動(dòng)作，關(guān)閉出入口保證安全。氣動(dòng)式氣源大致為0.6MPa，當(dāng)氣源進(jìn)行充氣時(shí)，主閥上的先導(dǎo)閥開啟，通過閥瓣之間的平衡孔使得進(jìn)口端壓力泄壓，主閥的啟閉力**減小，易于主閥迅速開啟，主彈簧壓縮繃緊。主閥關(guān)閉通過泄放氣源或者通過火災(zāi)現(xiàn)場(chǎng)的高溫使易熔元件塞體里的易熔合金熔化，氣壓從塞孔里進(jìn)行泄壓，氣缸受迫于彈簧的壓力，主閥快速關(guān)閉切斷。在結(jié)構(gòu)上氣動(dòng)式緊急切斷閥由于結(jié)構(gòu)上的特殊性--驅(qū)動(dòng)部分和閥體部分較分離，因此更容易進(jìn)行維修和易損件（氣缸O型圈）的更換。</p><p style="text-indent:25px">彈簧緊急切斷閥，彈簧緊急切斷閥是在遇到突發(fā)情況斷電后緊急關(guān)閉閥門或者打開閥門，它的工作原理是：電動(dòng)彈簧緊急切斷閥在通電后電機(jī)電動(dòng)執(zhí)行器里面的卷簧，把扭矩力傳導(dǎo)至卷簧上，在斷電時(shí)卷簧釋放里面儲(chǔ)存的扭矩力，帶動(dòng)閥門迅速的關(guān)閉或者打開。它的優(yōu)點(diǎn)是關(guān)閉迅速，關(guān)閉時(shí)間只需1-2S。蓄電容緊急安全閥，蓄電容緊急安全閥是在執(zhí)行器內(nèi)部裝有蓄電容儲(chǔ)能裝置，執(zhí)行器通電正常運(yùn)轉(zhuǎn)時(shí)，蓄電容充電，斷電時(shí)蓄電容釋放電能，帶動(dòng)電機(jī)、齒輪裝置開閉閥門。它的優(yōu)點(diǎn)是：蓄電容充放電時(shí)間短，壽命時(shí)間長(zhǎng)。電磁閥是新型的燃?xì)夤艿拦こ痰陌踩涮籽b置。燃?xì)饩o急切斷閥是安裝在燃?xì)鈨?chǔ)罐、管道出口處緊急時(shí)能夠快速切斷的閥門。</p><div
