下面小編(bian)就CCC電動(dong)防火(huo)閥(fa)作(zuo)詳細介(jie)紹

CCC電動防火閥作用

通風(feng)(feng)(feng)(feng)空(kong)調系(xi)統(tong)中，風(feng)(feng)(feng)(feng)機(ji)(ji)前一般會設一個常開式(shi)電動(dong)(dong)防火閥，當防火閥熔(rong)斷關(guan)閉時(shi)，聯(lian)動(dong)(dong)關(guan)閉風(feng)(feng)(feng)(feng)機(ji)(ji)，避免風(feng)(feng)(feng)(feng)機(ji)(ji)在(zai)風(feng)(feng)(feng)(feng)道關(guan)閉后繼續運行，起到(dao)保護風(feng)(feng)(feng)(feng)機(ji)(ji)的作用。地鐵通風(feng)(feng)(feng)(feng)空(kong)調系(xi)統(tong)比較復雜，不同系(xi)統(tong)下常開式(shi)電動(dong)(dong)防火閥與風(feng)(feng)(feng)(feng)機(ji)(ji)的聯(lian)動(dong)(dong)功能各不相同。

CCC電動防火閥的定義

電動防火閥有兩種：

一(yi)、采(cai)用FF1編(bian)號(hao)，是(shi)常開(kai)式電(dian)動(dong)(dong)防煙防火(huo)閥，正常狀態常開(kai)，電(dian)動(dong)(dong)操作(zuo)，電(dian)動(dong)(dong)或手動(dong)(dong)復位，70°C熔斷(duan)關閉防火(huo)閥，用于送、排風管道;

二(er)、采用FP1編(bian)號，是常(chang)開式電動排煙(yan)防(fang)(fang)火(huo)閥，正常(chang)狀態(tai)常(chang)開，電動操作，電動或手動復位，280°C熔(rong)斷關(guan)閉(bi)防(fang)(fang)火(huo)閥，用于排煙(yan)管道(dao)或排風兼排煙(yan)管道(dao)。兩(liang)種防(fang)(fang)火(huo)閥的區別在于熔(rong)斷器(qi)的熔(rong)斷溫度不(bu)同。
