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，市場上常見的推薦防火閥均為常閉形式，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，防火閥廠家在(zai)空調送(song)回(hui)風(feng)(feng)(feng)干(gan)管(guan)，通風(feng)(feng)(feng)風(feng)(feng)(feng)機進出口(kou)，風(feng)(feng)(feng)井入(ru)口(kou)，管(guan)道穿越防(fang)(fang)火(huo)(huo)分(fen)區 / 變形縫(feng) / 重要(yao)(yao)房(fang)間 / 機房(fang) / 火(huo)(huo)災(zai)危險性大的房(fang)間的隔墻或(huo)樓板，垂直風(feng)(feng)(feng)管(guan)與(yu)每層水平風(feng)(feng)(feng)管(guan)連接處。等很多場合都需要(yao)(yao)設(she)置防(fang)(fang)火(huo)(huo)閥(fa)(fa)。 空調新(xin)風(feng)(feng)(feng)取(qu)(qu)風(feng)(feng)(feng)管(guan)是否需要(yao)(yao)安(an)裝防(fang)(fang)火(huo)(huo)閥(fa)(fa)？一般不需要(yao)(yao)。特(te)別是如果(guo)回(hui)風(feng)(feng)(feng)、送(song)風(feng)(feng)(feng)均安(an)裝防(fang)(fang)火(huo)(huo)閥(fa)(fa)之后，新(xin)風(feng)(feng)(feng)取(qu)(qu)風(feng)(feng)(feng)口(kou)就(jiu)沒(mei)有必要(yao)(yao)在(zai)安(an)裝防(fang)(fang)火(huo)(huo)閥(fa)(fa)了。并且(qie)一般取(qu)(qu)風(feng)(feng)(feng)口(kou)位(wei)于(yu)室(shi)外，且(qie)按(an)照規(gui)范要(yao)(yao)求與(yu)排煙口(kou)保持10 m以上(shang)(shang)的水平距(ju)離或(huo)3 m以上(shang)(shang)的垂直距(ju)離（ 排煙口(kou)在(zai)上(shang)(shang) ），一般煙氣(qi)不會(hui)從新(xin)風(feng)(feng)(feng)口(kou)進入(ru)空調，所以一般不需要(yao)(yao)安(an)裝防(fang)(fang)火(huo)(huo)閥(fa)(fa)。

消(xiao)(xiao)聲器(qi)是利用(yong)聲的(de)(de)吸(xi)收、反射(she)(she)、干涉等原(yuan)理，降低通風與(yu)空調系統中(zhong)氣(qi)(qi)流噪(zao)聲的(de)(de)裝置。根據(ju)消(xiao)(xiao)聲原(yuan)理的(de)(de)不同(tong)可以分(fen)為阻(zu)性(xing)、抗性(xing)、共振型和(he)復合型等。一、阻(zu)性(xing)消(xiao)(xiao)聲器(qi),阻(zu)性(xing)消(xiao)(xiao)聲器(qi)利用(yong)吸(xi)聲材(cai)(cai)料(liao)(liao)的(de)(de)吸(xi)聲作用(yong)而消(xiao)(xiao)聲的(de)(de)。其(qi)構造是把吸(xi)聲材(cai)(cai)料(liao)(liao)固定在(zai)氣(qi)(qi)流流動(dong)的(de)(de)管道內壁，或按一定方式(shi)排列在(zai)管道或殼體內構成(cheng)阻(zu)性(xing)消(xiao)(xiao)聲器(qi)，吸(xi)聲材(cai)(cai)料(liao)(liao)能(neng)夠把入射(she)(she)在(zai)其(qi)上的(de)(de)聲能(neng)部(bu)分(fen)地吸(xi)收掉。聲能(neng)之所以能(neng)被(bei)吸(xi)收，是由于吸(xi)聲材(cai)(cai)料(liao)(liao)的(de)(de)多(duo)孔性(xing)和(he)松散性(xing)。當聲波(bo)進入孔隙，引起(qi)孔隙中(zhong)的(de)(de)空氣(qi)(qi)和(he)材(cai)(cai)料(liao)(liao)產生微小的(de)(de)振動(dong)，由于摩擦和(he)粘(zhan)滯阻(zu)力。使(shi)相當一部(bu)分(fen)聲能(neng)化為熱能(neng)而被(bei)吸(xi)收掉。
