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，大渡口不銹鋼通風管道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，不銹鋼通風管道廠家為了(le)截斷(duan)高溫煙(yan)氣在排(pai)煙(yan)管路中流動(dong)，防止火勢蔓延到(dao)另(ling)一(yi)防火分區，當排(pai)出的(de)煙(yan)氣溫度達到(dao)280℃時(shi)，排(pai)煙(yan)防火閥(fa)(fa)、排(pai)煙(yan)口上熔斷(duan)器動(dong)作，閥(fa)(fa)門(men)必(bi)須自(zi)動(dong)關閉，阻(zu)止排(pai)煙(yan)。由此可見，防火閥(fa)(fa)、排(pai)煙(yan)閥(fa)(fa)做到(dao)了(le)該通則通，該斷(duan)則斷(duan)的(de)隔煙(yan)阻(zu)火作用。
