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排煙管道均為常閉形式，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，排煙管道價格在(zai)空調(diao)送回風(feng)(feng)(feng)(feng)(feng)干管(guan)，通風(feng)(feng)(feng)(feng)(feng)風(feng)(feng)(feng)(feng)(feng)機進出口(kou)，風(feng)(feng)(feng)(feng)(feng)井入口(kou)，管(guan)道穿(chuan)越防(fang)(fang)(fang)火(huo)(huo)分(fen)區 / 變形縫 / 重(zhong)要(yao)房間 / 機房 / 火(huo)(huo)災危險性(xing)大的房間的隔墻(qiang)或樓板，垂直風(feng)(feng)(feng)(feng)(feng)管(guan)與(yu)每層水平(ping)風(feng)(feng)(feng)(feng)(feng)管(guan)連接處。等很多場合(he)都需(xu)要(yao)設(she)置防(fang)(fang)(fang)火(huo)(huo)閥(fa)。 空調(diao)新(xin)風(feng)(feng)(feng)(feng)(feng)取(qu)(qu)(qu)風(feng)(feng)(feng)(feng)(feng)管(guan)是(shi)否需(xu)要(yao)安(an)裝(zhuang)防(fang)(fang)(fang)火(huo)(huo)閥(fa)？一(yi)般(ban)(ban)不需(xu)要(yao)。特別是(shi)如(ru)果(guo)回風(feng)(feng)(feng)(feng)(feng)、送風(feng)(feng)(feng)(feng)(feng)均(jun)安(an)裝(zhuang)防(fang)(fang)(fang)火(huo)(huo)閥(fa)之(zhi)后，新(xin)風(feng)(feng)(feng)(feng)(feng)取(qu)(qu)(qu)風(feng)(feng)(feng)(feng)(feng)口(kou)就沒有必要(yao)在(zai)安(an)裝(zhuang)防(fang)(fang)(fang)火(huo)(huo)閥(fa)了。并(bing)且(qie)(qie)一(yi)般(ban)(ban)取(qu)(qu)(qu)風(feng)(feng)(feng)(feng)(feng)口(kou)位于室外，且(qie)(qie)按照規范要(yao)求與(yu)排煙(yan)(yan)口(kou)保持10 m以(yi)上的水平(ping)距離或3 m以(yi)上的垂直距離（ 排煙(yan)(yan)口(kou)在(zai)上 ），一(yi)般(ban)(ban)煙(yan)(yan)氣不會從(cong)新(xin)風(feng)(feng)(feng)(feng)(feng)口(kou)進入空調(diao)，所以(yi)一(yi)般(ban)(ban)不需(xu)要(yao)安(an)裝(zhuang)防(fang)(fang)(fang)火(huo)(huo)閥(fa)。
