功能，PST部分行程測試是自動在線測試的一種，閥門在不影響工廠正常運行的條件下局部行程動作(例如從多方面全開狀態(tài)關(guān)到90%，然后回到多方面全開)，以此來證明閥門的完好性。該閥門定期自動動作，首先有可能是PST功能影響，后將PST功能關(guān)閉，故障解除，至于閥門在自檢過程中無法回到多方面開位，主要原因是先期調(diào)試時，行程調(diào)試沒做好造成。　　防爆燃氣緊急切斷閥普遍應(yīng)用于燃氣管網(wǎng)系統(tǒng)，燃氣熱電廠車間，燃氣鍋爐房和住宅設(shè)施。</p><div

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。湖南防爆緊急切斷閥有什么用</p></p><br
