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，市場上常見的高品質不銹鋼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，不銹鋼通風管批發在(zai)空調(diao)(diao)送回風(feng)干管(guan)，通(tong)風(feng)風(feng)機進出口(kou)，風(feng)井入口(kou)，管(guan)道(dao)穿越防(fang)(fang)火分區 / 變形(xing)縫 / 重要(yao)(yao)(yao)房(fang)間(jian)(jian) / 機房(fang) / 火災危險性大的房(fang)間(jian)(jian)的隔墻或樓板，垂直風(feng)管(guan)與每層水平風(feng)管(guan)連接處。等(deng)很多場合(he)都需要(yao)(yao)(yao)設置防(fang)(fang)火閥。 空調(diao)(diao)新(xin)風(feng)取(qu)風(feng)管(guan)是否需要(yao)(yao)(yao)安裝(zhuang)防(fang)(fang)火閥？一(yi)(yi)般(ban)不需要(yao)(yao)(yao)。特別是如果回風(feng)、送風(feng)均(jun)安裝(zhuang)防(fang)(fang)火閥之后，新(xin)風(feng)取(qu)風(feng)口(kou)就沒有必要(yao)(yao)(yao)在(zai)安裝(zhuang)防(fang)(fang)火閥了。并且一(yi)(yi)般(ban)取(qu)風(feng)口(kou)位于室(shi)外(wai)，且按照(zhao)規范要(yao)(yao)(yao)求與排煙口(kou)保(bao)持10 m以上(shang)(shang)的水平距離或3 m以上(shang)(shang)的垂直距離（ 排煙口(kou)在(zai)上(shang)(shang) ），一(yi)(yi)般(ban)煙氣不會(hui)從新(xin)風(feng)口(kou)進入空調(diao)(diao)，所(suo)以一(yi)(yi)般(ban)不需要(yao)(yao)(yao)安裝(zhuang)防(fang)(fang)火閥。
