style="text-indent:25px">　由于緊急切斷閥是通過液化氣在管道內(nèi)壓力變化快速關(guān)閉閥門，因此要求管道壓力波動不能過大。壓力控制器關(guān)閉閥門設(shè)定的較低壓力為0。58MPa，但隨著季節(jié)改變和庫存上升，管道壓力在0。6～1。2MPa變化，根據(jù)液化石油氣性質(zhì)，管線泄漏時，隨著管道壓力高低分布，管道壓力下降產(chǎn)生在不同時間，造成切斷閥不能及時關(guān)閉。切斷閥開關(guān)狀態(tài)未遠(yuǎn)傳至中控室，無法監(jiān)控，當(dāng)切斷閥液壓部分出現(xiàn)故障時，閥門將會自動關(guān)閉，容易發(fā)生管線超壓事故。改進(jìn)實(shí)施改進(jìn)目的是當(dāng)管道出現(xiàn)故障發(fā)生大量泄漏而壓力變化又不及時，采取人工遠(yuǎn)程關(guān)閉切斷閥，保證安全。分析認(rèn)為，要關(guān)閉緊急切斷閥，則需連通液壓控制管和液壓控制回油管，使手動卸壓閥卸壓，為此在二者之間加裝電磁閥，在閥體連桿安裝閥門回訊器。由于電磁閥安裝在緊急切斷閥液壓油路，液壓油路主要為手動卸壓閥提供動力，流量較小且壓力≤0。6MPa，同時為保留切斷閥原有功能，選擇內(nèi)螺紋防爆型常閉電磁閥(DC24V，流量口徑12mm，壓力0。6MPa)。實(shí)際使用時，上位機(jī)控制電磁閥打開，液壓油經(jīng)回油管進(jìn)入液壓油箱，切斷閥關(guān)閉，切斷管道液化氣。同時球閥轉(zhuǎn)動過程中帶動閥桿上端回訊器凸輪轉(zhuǎn)動，向上位機(jī)反饋信號，上位機(jī)顯示切斷閥開關(guān)狀態(tài)。四川防爆緊急切斷閥生產(chǎn)線氣密性是決定閥門關(guān)閉后截流能力的大小。</p><div
