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，大渡口排煙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，排煙管道價格為了截斷高(gao)溫煙(yan)氣在排(pai)煙(yan)管路中(zhong)流動，防止火(huo)勢蔓(man)延到另一防火(huo)分區(qu)，當排(pai)出(chu)的煙(yan)氣溫度達到280℃時，排(pai)煙(yan)防火(huo)閥(fa)、排(pai)煙(yan)口(kou)上(shang)熔斷器動作，閥(fa)門必須自動關閉，阻(zu)止排(pai)煙(yan)。由此可見，防火(huo)閥(fa)、排(pai)煙(yan)閥(fa)做到了該(gai)通則通，該(gai)斷則斷的隔煙(yan)阻(zu)火(huo)作用。
