style="text-indent:25px">防火閥一般分為兩種：一種只輸出動作信號（像70°防火閥）這種防火閥的模塊只需要信號線加反饋線；防火閥的設置：為了阻止火災時火勢和有毒高溫煙氣通過風管蔓延擴大，在通風、空調(diào)系統(tǒng)的風管上需設置防火閥。廚房、浴室和廁所等的排風管道與豎井連接時也應采取相應措施防止火勢沿著排風管在各樓層間蔓延。自動排煙防火閥：此類閥適用于設有感煙探測器自動報警控制和機械排煙的場所，安裝在排煙管道上，兼有自動排煙閥和防火閥的功能。平時處于關閉狀態(tài)，需要排煙時，其動作和功能與排煙閥相同，可自動開啟排煙。當管道內(nèi)氣流溫度達到280℃時，閥門靠裝有280℃易熔金屬的溫度熔斷器而自動關閉，切斷氣流，防止火災蔓延。三沙防火閥服務哪家好防火閥的熔斷片應裝在朝向火災危險性較大的一側。</p><div
