排煙閥是否存在常開的？這里的排煙閥也就相當于排煙口，對于常見的板式排煙口與多葉排煙口，市場上常見的推薦通風管均為常閉形式，一般不需要常開的排煙口。對于排風兼排煙系統的排煙口，可以采用“單層百葉 + 280 ℃ 電控排煙防火閥”進行控制。70 ℃防火閥的應用場合有哪些？防火閥應用場合很多，通風管批發在空(kong)調送(song)回風(feng)(feng)(feng)(feng)(feng)干管(guan)，通風(feng)(feng)(feng)(feng)(feng)風(feng)(feng)(feng)(feng)(feng)機進(jin)出(chu)口(kou)(kou)，風(feng)(feng)(feng)(feng)(feng)井入(ru)口(kou)(kou)，管(guan)道穿越防(fang)(fang)火分區 / 變形縫 / 重要(yao)(yao)房間(jian) / 機房 / 火災危(wei)險性大的(de)房間(jian)的(de)隔墻或(huo)樓板，垂(chui)直風(feng)(feng)(feng)(feng)(feng)管(guan)與每層水平風(feng)(feng)(feng)(feng)(feng)管(guan)連接處。等(deng)很多(duo)場合都(dou)需(xu)要(yao)(yao)設置防(fang)(fang)火閥。 空(kong)調新(xin)(xin)風(feng)(feng)(feng)(feng)(feng)取(qu)(qu)風(feng)(feng)(feng)(feng)(feng)管(guan)是(shi)否需(xu)要(yao)(yao)安裝(zhuang)防(fang)(fang)火閥？一(yi)(yi)般(ban)不(bu)(bu)需(xu)要(yao)(yao)。特別(bie)是(shi)如果回風(feng)(feng)(feng)(feng)(feng)、送(song)風(feng)(feng)(feng)(feng)(feng)均安裝(zhuang)防(fang)(fang)火閥之后，新(xin)(xin)風(feng)(feng)(feng)(feng)(feng)取(qu)(qu)風(feng)(feng)(feng)(feng)(feng)口(kou)(kou)就沒有必要(yao)(yao)在安裝(zhuang)防(fang)(fang)火閥了。并且一(yi)(yi)般(ban)取(qu)(qu)風(feng)(feng)(feng)(feng)(feng)口(kou)(kou)位于室外，且按照(zhao)規范要(yao)(yao)求(qiu)與排煙(yan)口(kou)(kou)保(bao)持10 m以上(shang)的(de)水平距離或(huo)3 m以上(shang)的(de)垂(chui)直距離（ 排煙(yan)口(kou)(kou)在上(shang) ），一(yi)(yi)般(ban)煙(yan)氣不(bu)(bu)會從(cong)新(xin)(xin)風(feng)(feng)(feng)(feng)(feng)口(kou)(kou)進(jin)入(ru)空(kong)調，所以一(yi)(yi)般(ban)不(bu)(bu)需(xu)要(yao)(yao)安裝(zhuang)防(fang)(fang)火閥。
