style="text-indent:25px">防火閥用于建筑物內的中央空調風道系統(tǒng)中。當它安裝在通風、空調系統(tǒng)的送、回風管路上。一般用于平時送風、火災補風共用風管系統(tǒng)中，火災時可控制關閉不需要補風的房間；平時呈開啟狀態(tài)，火災時當管道內氣體溫度達到70℃時，易熔片熔斷，閥門在扭簧力作用下自動關閉，起到隔斷防火分區(qū)間的風道，防止火焰漫延。在排煙風管中，其需要有一定時間內能滿足耐火穩(wěn)定性和耐火完整性要求，起隔煙阻火作用，則需要用280度的防火閥。它與70度的防火閥只是熔斷溫度不同，一般應用于火災排煙管穿越防火墻處，煙氣溫度超過280度時自動熔斷關閉，可聯(lián)動關閉排煙風機?；鹧嫒肭诛L道，高溫使閥門上的易熔合金熔解，或使記憶合金產(chǎn)生形變使閥門自動關閉，用于風道與防火分區(qū)貫穿的場合。排煙口、排煙閥主要設置在排煙系統(tǒng)的管道上，或安裝在消防排煙風機的吸入口處，平時處于關閉狀態(tài)。</p><div

防火閥選用主要控制參數(shù)為規(guī)格等。防火閥適用于通風空調系統(tǒng)，除公共建筑的廚房排油煙系統(tǒng)用防火閥，動作溫度為150℃外，一般通風空調系統(tǒng)用防火閥動作溫度為70℃。防火閥適用于通風、空調或排煙系統(tǒng)的管道上，基本功能和適用范圍，選用閥門時應注意閥門的功能，如常開還是常閉、自動關閉開啟、手動關閉開啟、手動復位、訊號輸出、遠距離控制等要求。閥門若與風機聯(lián)動的應選用帶雙微動開關裝置。閥體葉片應為鋼板，厚度為2~6mm，閥體為不燃材料制作，轉動部件應采用耐腐蝕的金屬材料，并轉動靈活。閥門的外殼厚度不得小于2mm。易融部件應符合消防部門的認可標準。常開型排煙防火閥平時呈常開狀態(tài)，火災發(fā)生時，閥門保持開啟狀態(tài)。清遠防火閥費用</p><p

style="text-indent:25px">排煙防火閥設置常開或常閉，視排煙口的形式而定，當設常閉的排煙口時，排煙支管上設常開的排煙防火閥。當設普通常開型風口時，排煙支管上設常閉的排煙防火閥。當設常閉型**防火排煙口時，則排煙支管上不設排煙防火閥。設置機械排煙的地下室應考慮進風設施，當采用機械進風系統(tǒng)時，應在風機入口管道上設置70℃熔斷的防火閥。對于機械加壓送風系統(tǒng)，可在加壓送風機入口管道上設置70℃熔斷的防火閥，以防止新風入口受火、煙威脅，將煙氣輸送至樓層內。在排煙風機的入口總管上應設置當煙氣溫度超過280℃時能自動關閉的排煙防火閥，且應與排煙風機連鎖，當排煙防火閥關閉時，風機停止運轉。梧州防火閥質量</p><p
