style="text-indent:25px">電磁式燃氣緊急切斷閥品種很多，本文按幾個主要部件的不同形式進行分類，并對各種形式的特點進行簡要敘述。電磁式燃氣緊急切斷閥很少用于高壓，一方面是因為壓力越高所需控制閥門的驅(qū)動力越大，生產(chǎn)成本越高；另一方面，因為對于城鎮(zhèn)燃氣來說，高壓環(huán)境一般*存在于門站和主輸配管線上，此類環(huán)境一般要求安全閥在發(fā)生事故時，無需進行外部控制即可快速關(guān)斷，避免了用電產(chǎn)生的安全隱患，因此，一般在此類環(huán)境中使用自力式燃氣緊急切斷閥。燃氣緊急切斷閥結(jié)構(gòu)簡單，反應(yīng)靈敏，動作可靠。</p><div
