切斷閥的用途很廣，可用于切斷煤氣、助燃空氣、冷風及煙氣。煤氣切斷閥是把燃燒器與煤氣管道切斷。助燃空氣切斷閥是將燃燒器與助燃空氣管道切斷。熱風爐在送風期用燃燒器切斷閥將熱風爐與燃燒器或煤氣系統(tǒng)及助燃空氣系統(tǒng)隔斷。煙道閥使熱風爐與煙道隔離。冷風閥的用途是在熱風爐燃燒期把冷風管道與熱風爐隔開。當冷風管道內壓力下降時，中國香港瓦克夏WAUKESHA柴油機進氣切斷閥，高爐內的煤氣可能通過混風管滲入冷風管道，中國香港瓦克夏WAUKESHA柴油機進氣切斷閥，形成性氣體，為避免這種情況發(fā)生，在混風調節(jié)閥與熱風管道之間的混風管道上設置混風切斷閥。[3]主要應用于以下場合：1、與可燃氣體泄漏監(jiān)測儀器聯(lián)接，當儀器檢測到可燃氣體泄漏時，中國香港瓦克夏WAUKESHA柴油機進氣切斷閥，自動快速關閉主供氣閥門，切斷燃氣的供給，及時制止惡性事故的發(fā)生；2、與熱力設備的極限溫度壓力安全控制器聯(lián)接，當設備內檢測點的溫度壓力超過設定的極限數(shù)值時，自動快速關閉供氣閥門，停止燃料的供給；3、與高層建筑的**消防報警系統(tǒng)聯(lián)接，當大廈發(fā)生火警時，自動切斷大廈內的燃氣供應，防止煤氣的發(fā)生；4、在城市或工廠的燃氣供應管網內設置ZCR燃氣緊急切斷閥，可在**控制室內集中控制，遠程遙控緊急關閉事故現(xiàn)場的管線供氣。柴油機安全防爆產品供應商。中國香港瓦克夏WAUKESHA柴油機進氣切斷閥</p><div
