style="text-indent:25px">流體作業(yè)狀態(tài)時(shí)油缸用手油泵充入2～4MPa液壓油壓力，油缸活塞桿推動(dòng)凸輪杠桿，開啟主閥閥瓣，主彈簧壓縮繃緊。當(dāng)裝卸作業(yè)時(shí)如突然發(fā)生火災(zāi)、泄漏等意外緊急事故時(shí)，通過在場(chǎng)的工作人員操作泄放手油泵的油壓，或者裝在油缸上的易熔元件在溫度超過70±5℃時(shí)，易熔元件中的易熔合金自動(dòng)熔化，液壓油就會(huì)從塞孔中漏出，泄放油缸中的油壓，此時(shí)油缸活塞桿回退，凸輪杠桿回彈，主閥閥瓣也快速關(guān)閉切斷，從而防止燃油泄漏和火災(zāi)事故的進(jìn)一步擴(kuò)大。同時(shí)液壓式緊急切斷閥常常附帶有過流切斷保護(hù)功能，當(dāng)閥門出口介質(zhì)的流量大于額定流量時(shí)，主閥能夠?qū)崿F(xiàn)自動(dòng)關(guān)閉，起到了限流保護(hù)作用。電磁式緊急切斷閥的密封副基本上采用軟密封結(jié)構(gòu)，以保證關(guān)閉狀態(tài)下氣體介質(zhì)零泄漏。</p><div
