style="text-indent:25px">自力式緊急切斷閥，若管道壓力>0。4MPa，球閥兩端引壓管線將壓力傳至壓力控制器，壓力連桿向上推動。手動液壓泵的部分液壓油由控制液管進入三通控制閥，經(jīng)液壓控制管進入手動卸壓閥推動旋塞向右移動，此時連通，關(guān)閉，手動液壓泵液壓油進入液壓執(zhí)行器液壓缸，推動活塞向左移動，帶動閥體連桿轉(zhuǎn)動，打開切斷閥;若管道壓力<0。4MPa，在三通控制閥內(nèi)彈簧作用下，壓力連桿向下運動，液壓控制管和液壓控制回油管連通，手動卸壓閥推動旋塞向左移動，關(guān)閉，連通，液壓執(zhí)行器彈簧推動活塞向右移動，帶動閥體連桿轉(zhuǎn)動，關(guān)閉切斷閥。</p><p style="text-indent:25px">液壓式緊急切斷閥是目前較為常用的緊急切斷閥，該閥主要由手油泵、油路系統(tǒng)、泄放系統(tǒng)（易熔元件）和閥體等部件組成。適用于液化石油氣、液氨等氣、液相介質(zhì)儲配站或者汽車槽車的貯罐出入口上，在緊急情況時該閥門通過液壓油進行遠距離快速操作控制，或者通過本體自帶的易熔元件進行油壓泄放進行快速切斷動作，關(guān)閉出入口保證貯運系統(tǒng)的安全。平時不進行作業(yè)時液壓式緊急切斷閥一般保持關(guān)閉狀態(tài)，一是防止液化石油氣內(nèi)的雜質(zhì)聚積在閥門密封面上，導(dǎo)致密封不良，二是防止長期保持高壓狀態(tài)的軟管疲勞損害和油缸的密封元件失效，導(dǎo)致液壓油泄漏，三是防止長期保持緊繃狀態(tài)的主彈簧彈性失效現(xiàn)象，導(dǎo)致緊急切斷時，切斷時間緩慢。緊急切斷閥又叫做安全切斷閥。</p><div

style="text-indent:25px">根據(jù)安全閥的結(jié)構(gòu)可分為：重錘（杠桿）式安全閥：用杠桿和重錘來平衡閥瓣的壓力。重錘式安全閥靠移動重錘的位置或改變重錘的重量來調(diào)整壓力。它的優(yōu)點在于結(jié)構(gòu)簡單；缺點是比較笨重回座力低。這種結(jié)構(gòu)的安全閥只能用于固定的設(shè)備上。彈簧式安全閥：利用壓縮彈簧的力來平衡閥瓣的壓力并使之密封。彈簧式安全閥靠調(diào)節(jié)彈簧的壓縮量來調(diào)整壓力。它的優(yōu)點在于比重錘式安全閥體積小、輕便，靈敏度高，安裝位置不受嚴格限制；缺點是作用在閥桿上的力隨彈簧變形而發(fā)生變化。同時必須注意彈簧的隔熱和散熱問題。彈簧式安全閥的彈簧作用力一般不要超過2000公斤。因為過大過硬的彈簧不適于精確的工作。脈沖式安全閥：脈沖式安全閥由主閥和輔閥組成。主閥和輔閥連在一起，通過輔閥的脈沖作用帶動主閥動作。緊急切斷閥又叫安全切斷閥。河南防爆緊急切斷閥加工廠</p><p

style="text-indent:25px">ZCRB防爆燃氣緊急切斷閥功能和工作原理：該系列閥門是常開脈沖觸發(fā)式電磁閥，具有事故自鎖和手動復(fù)位功能。閥門在日常工作中處于常開狀態(tài)，電磁閥線圈處于斷電狀態(tài)，不消耗電能。當(dāng)事故發(fā)生時，閥門線圈立即通電，觸發(fā)閥門快速關(guān)閉并進入自鎖狀態(tài)。此時，即使斷電，閥門仍處于自鎖閉合狀態(tài)，不會自動重新打開。該閥采用先導(dǎo)式閥瓣，易于打開。即使壓力達到6bar，也很容易打開。直徑大于DN125。杠桿手柄用于使閥門以較低的力度和速度到達目標開關(guān)。當(dāng)工作人員處理事故并手動重新打開閥門時，將恢復(fù)供氣。可根據(jù)要求提供帶斷電關(guān)閉功能的常閉緊急切斷閥。河南防爆緊急切斷閥加工廠</p></p><br
