下面小(xiao)編(bian)就CCC電動防火閥作(zuo)詳(xiang)細(xi)介紹(shao)
CCC電動防火(huo)閥作用(yong)
通風(feng)(feng)空(kong)調系(xi)統中,風(feng)(feng)機(ji)前一般會設一個常開(kai)式(shi)電動(dong)防火(huo)閥(fa),當(dang)防火(huo)閥(fa)熔斷關(guan)閉時,聯(lian)動(dong)關(guan)閉風(feng)(feng)機(ji),避免(mian)風(feng)(feng)機(ji)在(zai)風(feng)(feng)道關(guan)閉后繼續(xu)運行,起到保護風(feng)(feng)機(ji)的(de)(de)作用。地鐵通風(feng)(feng)空(kong)調系(xi)統比較(jiao)復雜,不同(tong)系(xi)統下常開(kai)式(shi)電動(dong)防火(huo)閥(fa)與風(feng)(feng)機(ji)的(de)(de)聯(lian)動(dong)功能各(ge)不相同(tong)。
CCC電動防火閥的定義
電動防火閥有兩種:
一、采用(yong)FF1編(bian)號,是常(chang)開式(shi)電(dian)(dian)動(dong)防煙(yan)防火(huo)閥,正常(chang)狀態常(chang)開,電(dian)(dian)動(dong)操作,電(dian)(dian)動(dong)或手動(dong)復位,70°C熔斷(duan)關閉防火(huo)閥,用(yong)于送、排(pai)風管(guan)道(dao);
二、采用FP1編號(hao),是(shi)常(chang)開式電(dian)動(dong)(dong)排煙防火(huo)閥(fa),正常(chang)狀態(tai)常(chang)開,電(dian)動(dong)(dong)操作,電(dian)動(dong)(dong)或手動(dong)(dong)復(fu)位(wei),280°C熔(rong)斷(duan)關(guan)閉防火(huo)閥(fa),用于(yu)排煙管(guan)道或排風兼(jian)排煙管(guan)道。兩(liang)種(zhong)防火(huo)閥(fa)的(de)區別在于(yu)熔(rong)斷(duan)器的(de)熔(rong)斷(duan)溫度不同。
