在空調送風系統中，空調送風機送出的風必須通過主干管分配到支管中；在排煙系統中，煙氣由支管到主干管后，進入排煙風機排出。當建筑物內發生火災時，在通風、空調系統中，四川不銹鋼通風管為了防止火勢通過送風系統蔓延，當送風系統中氣體溫度達到70℃時，防火閥機構上熔斷器動作，閥門亦迅速關閥，切斷煙氣與火勢沿風管蔓延的通路。同樣，在排煙系統中，發生火災時，排煙閥開啟，進行排煙，不銹鋼通風管廠家為(wei)了截斷高溫煙(yan)(yan)氣(qi)(qi)在排煙(yan)(yan)管路中(zhong)流動(dong)(dong)，防(fang)止火(huo)(huo)勢蔓延到(dao)另一防(fang)火(huo)(huo)分區，當排出的煙(yan)(yan)氣(qi)(qi)溫度達到(dao)280℃時，排煙(yan)(yan)防(fang)火(huo)(huo)閥(fa)(fa)(fa)、排煙(yan)(yan)口上熔斷器動(dong)(dong)作，閥(fa)(fa)(fa)門必須自動(dong)(dong)關(guan)閉(bi)，阻止排煙(yan)(yan)。由此可見，防(fang)火(huo)(huo)閥(fa)(fa)(fa)、排煙(yan)(yan)閥(fa)(fa)(fa)做到(dao)了該(gai)通則通，該(gai)斷則斷的隔煙(yan)(yan)阻火(huo)(huo)作用(yong)。
