style="text-indent:25px">走道長，設置了機械排煙系統(tǒng)，每層樓只有一個防煙分區(qū)。每層的排煙主管上設計了一個電動的常閉的防火閥，每層的每個排煙口又設計一個電動的常閉的排煙閥，消防排煙風機的吸入口處也設計了一個電動的常閉的排煙防火閥。顯然，這種設計存在功能浪費，也是模塊、閥門、建筑成本的浪費。建議:方法之一是把排煙口的排煙閥和模塊取消，風口改成單層百葉;方法二是把每層的排煙主管上電動的常閉的防火閥改成常開的280度關閉的防火閥，控制模塊改為一般的監(jiān)視模塊。這兩種方法同樣能達到消防規(guī)范要求，并且實際控制起來也十分可靠。</p><p style="text-indent:25px">安裝在通風、空氣調節(jié)系統(tǒng)的送、回風管道上，平時呈開啟狀態(tài)，火災時當管道內煙氣溫度達到70℃時關閉，起隔煙阻火作用，主要為了保證防火完整性。對于防火類閥門的控制和具備的功能，防火規(guī)范和防排煙標準并未做明確的說明，只能在閥門規(guī)范里面看到只言片語，對于防火閥的功能應該以實際工程需求為主。防火規(guī)范附表中有“防煙防火閥”的表述，但是在閥門規(guī)范和消防認證中并未出現(xiàn)“防煙防火閥”的名稱，建議廢除的這個叫法，此附表是從老建規(guī)上直接搬過來的，應該說已經不適合現(xiàn)在的閥門體系了。結合消防認證產品報告和實際的工程需求，梳理出4種防火閥，應該足夠在工程中應用。防火閥是一種防火輔助設備，安裝于風管中間，當出現(xiàn)火情時能阻斷風管。</p><div
