style="text-indent:25px">燃氣緊急切斷閥按閉合方式分類，徑向閉合式是指切斷閥的閥口與氣流方向平行，閥瓣的運動方向與流體流向垂直的切斷形式，傳統(tǒng)意義上的切斷閥均采用徑向切斷形式。可知反向推力f反＞正向推力F正，且壓力越高f反與F正的差值越大，則需要的電磁力和彈簧力就越大，這就給閥的設計，尤其是彈簧的設計和鐵心材料的選取帶來困難，所以，這類切斷閥一般用于壓力較低的管道上。軸向閉合式是指切斷閥的閥口與進氣口、出氣口平行，與氣流方向垂直，且閥瓣的運動方向平行于氣流方向的一種切斷形式，采用此設計，整個切斷機構(gòu)均處于帶壓氣體內(nèi)，氣體的正向推力F與反向推力f處處相等，因此，其只需很小的電磁驅(qū)動力和彈簧力即可驅(qū)動閥門關閉。所以，這類切斷閥適用于壓力較高的管道上，理論上這類切斷閥在其較大承壓的范圍內(nèi)均可正常切斷。</p><p

燃氣緊急切斷閥是安裝在燃氣儲罐/管道出口處緊急時能夠快速切斷的閥門，利用電磁閥來控制閥門的關閉，是目前比較理想的安全閥之一。燃氣緊急切斷閥的主要集中在以下方面：與高層建筑的**消防泄露儀器系統(tǒng)相連接。當大廈發(fā)生火情時，自動切斷大廈內(nèi)的燃氣供應，防止意外情況的發(fā)生。在城市或工廠的燃氣供應管網(wǎng)內(nèi)設置燃氣緊急切斷閥，可在**控制室內(nèi)集中控制，遠距離遙控，緊急關閉故障現(xiàn)場的管線供氣。適用于煤氣、天燃氣及液化石油氣等可燃氣體，普遍應用于供氣管網(wǎng)系統(tǒng)，燃氣熱能工廠車間，燃氣鍋爐房及住宅居住所的安全設施?？煽康募夹g性能；極低的負荷損失；極高的安全性能。傳統(tǒng)意義上的切斷閥均采用徑向切斷形式。寧夏防爆緊急切斷閥多少錢</p><p
