雖(sui)然在(zai)(zai)商業(ye)建(jian)(jian)(jian)(jian)筑(zhu)與多(duo)(duo)種居住房(fang)的(de)(de)被動(dong)消(xiao)防中(zhong)(zhong)，防火閥是關(guan)鍵組件(jian)，但(dan)在(zai)(zai)對建(jian)(jian)(jian)(jian)筑(zhu)和其居住者的(de)(de)安全保護中(zhong)(zhong)，很多(duo)(duo)管理者沒(mei)有意(yi)識到(dao)防火閥的(de)(de)作(zuo)用以及規(gui)定時間(jian)間(jian)隔內，防火閥的(de)(de)檢測、清潔及維護的(de)(de)重要意(yi)義。在(zai)(zai)商業(ye)建(jian)(jian)(jian)(jian)筑(zhu)中(zhong)(zhong)的(de)(de)建(jian)(jian)(jian)(jian)造中(zhong)(zhong)我們總會(hui)遇到(dao)一些麻(ma)煩，試圖在(zai)(zai)能(neng)源效率(lv)與室內空(kong)氣(qi)(qi)質量之(zhi)間(jian)尋求平衡就是其中(zhong)(zhong)。大多(duo)(duo)商業(ye)建(jian)(jian)(jian)(jian)筑(zhu)通(tong)過機械(xie)通(tong)風(feng)或(huo)空(kong)調系統(tong)解決，能(neng)夠(gou)測量和控制整個建(jian)(jian)(jian)(jian)筑(zhu)的(de)(de)空(kong)氣(qi)(qi)變化。在(zai)(zai)通(tong)風(feng)管道(dao)系統(tong)的(de)(de)安裝上(shang)就存在(zai)(zai)上(shang)面(mian)(mian)提(ti)到(dao)的(de)(de)問題(ti)———如何在(zai)(zai)延(yan)遲(chi)或(huo)阻(zu)止(zhi)火災蔓延(yan)的(de)(de)建(jian)(jian)(jian)(jian)筑(zhu)防火分隔與所允許(xu)空(kong)氣(qi)(qi)自(zi)由流通(tong)的(de)(de)需要之(zhi)間(jian)達(da)到(dao)平衡。滿足空(kong)氣(qi)(qi)自(zi)由流通(tong)需要不可避免地再(zai)引入一條(tiao)通(tong)道(dao)，而這(zhe)卻加快了(le)(le)火勢的(de)(de)蔓延(yan)———利用通(tong)風(feng)管道(dao)系統(tong)使用的(de)(de)通(tong)道(dao)。毫無疑(yi)問，這(zhe)中(zhong)(zhong)斷(duan)了(le)(le)防火分隔，充當了(le)(le)建(jian)(jian)(jian)(jian)筑(zhu)被動(dong)消(xiao)防護面(mian)(mian)的(de)(de)“裂口(kou)”。

消(xiao)聲(sheng)(sheng)器是利用聲(sheng)(sheng)的(de)(de)(de)(de)吸(xi)(xi)收(shou)、反(fan)射、干涉等(deng)(deng)原(yuan)理(li)，降低(di)通風與空調系統中氣流(liu)噪聲(sheng)(sheng)的(de)(de)(de)(de)裝置。根據(ju)消(xiao)聲(sheng)(sheng)原(yuan)理(li)的(de)(de)(de)(de)不同可以分為阻性(xing)(xing)、抗性(xing)(xing)、共振型和復合型等(deng)(deng)。一(yi)、阻性(xing)(xing)消(xiao)聲(sheng)(sheng)器,阻性(xing)(xing)消(xiao)聲(sheng)(sheng)器利用吸(xi)(xi)聲(sheng)(sheng)材料(liao)的(de)(de)(de)(de)吸(xi)(xi)聲(sheng)(sheng)作用而消(xiao)聲(sheng)(sheng)的(de)(de)(de)(de)。其構造(zao)是把(ba)吸(xi)(xi)聲(sheng)(sheng)材料(liao)固定在(zai)氣流(liu)流(liu)動(dong)的(de)(de)(de)(de)管道(dao)內(nei)壁，或按一(yi)定方式排列在(zai)管道(dao)或殼(ke)體內(nei)構成阻性(xing)(xing)消(xiao)聲(sheng)(sheng)器，吸(xi)(xi)聲(sheng)(sheng)材料(liao)能夠把(ba)入射在(zai)其上的(de)(de)(de)(de)聲(sheng)(sheng)能部分地吸(xi)(xi)收(shou)掉。聲(sheng)(sheng)能之所(suo)以能被吸(xi)(xi)收(shou)，是由于吸(xi)(xi)聲(sheng)(sheng)材料(liao)的(de)(de)(de)(de)多(duo)孔(kong)性(xing)(xing)和松(song)散性(xing)(xing)。當聲(sheng)(sheng)波進入孔(kong)隙(xi)，引(yin)起孔(kong)隙(xi)中的(de)(de)(de)(de)空氣和材料(liao)產生微小(xiao)的(de)(de)(de)(de)振動(dong)，由于摩擦(ca)和粘滯阻力。使相(xiang)當一(yi)部分聲(sheng)(sheng)能化為熱能而被吸(xi)(xi)收(shou)掉。

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天園地方管均為常閉形式，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，天園地方管價格在空(kong)調送回風(feng)(feng)(feng)(feng)(feng)干管，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)，管道穿越防(fang)火(huo)(huo)分區 / 變形縫 / 重要(yao)(yao)房間(jian)(jian) / 機房 / 火(huo)(huo)災(zai)危險性大的(de)(de)房間(jian)(jian)的(de)(de)隔墻(qiang)或樓板，垂直風(feng)(feng)(feng)(feng)(feng)管與(yu)每層水平風(feng)(feng)(feng)(feng)(feng)管連(lian)接(jie)處。等很多場合都(dou)需(xu)要(yao)(yao)設置防(fang)火(huo)(huo)閥(fa)。 空(kong)調新風(feng)(feng)(feng)(feng)(feng)取(qu)風(feng)(feng)(feng)(feng)(feng)管是(shi)否(fou)需(xu)要(yao)(yao)安(an)(an)裝(zhuang)(zhuang)防(fang)火(huo)(huo)閥(fa)？一般不(bu)需(xu)要(yao)(yao)。特別是(shi)如(ru)果回風(feng)(feng)(feng)(feng)(feng)、送風(feng)(feng)(feng)(feng)(feng)均安(an)(an)裝(zhuang)(zhuang)防(fang)火(huo)(huo)閥(fa)之后，新風(feng)(feng)(feng)(feng)(feng)取(qu)風(feng)(feng)(feng)(feng)(feng)口(kou)就沒(mei)有必要(yao)(yao)在安(an)(an)裝(zhuang)(zhuang)防(fang)火(huo)(huo)閥(fa)了(le)。并且一般取(qu)風(feng)(feng)(feng)(feng)(feng)口(kou)位于室外，且按照規(gui)范要(yao)(yao)求與(yu)排(pai)煙(yan)口(kou)保持10 m以上(shang)的(de)(de)水平距離(li)或3 m以上(shang)的(de)(de)垂直距離(li)（ 排(pai)煙(yan)口(kou)在上(shang) ），一般煙(yan)氣(qi)不(bu)會從新風(feng)(feng)(feng)(feng)(feng)口(kou)進入空(kong)調，所(suo)以一般不(bu)需(xu)要(yao)(yao)安(an)(an)裝(zhuang)(zhuang)防(fang)火(huo)(huo)閥(fa)。

在(zai)葉(xie)(xie)輪(lun)(lun)運轉初(chu)期(qi)(qi)及所(suo)有(you)定期(qi)(qi)檢查的時候，只(zhi)要(yao)(yao)(yao)一有(you)機會，都必(bi)(bi)須(xu)檢查葉(xie)(xie)輪(lun)(lun)是否出現裂(lie)紋、磨(mo)損、積塵(chen)(chen)等缺陷。只(zhi)要(yao)(yao)(yao)有(you)可能，都必(bi)(bi)須(xu)使葉(xie)(xie)輪(lun)(lun)保(bao)持清潔狀態(tai)，并(bing)定期(qi)(qi)用鋼絲刷刷去(qu)上面的積塵(chen)(chen)和銹皮等，因為隨著(zhu)運行(xing)時間(jian)的加長，這(zhe)些灰塵(chen)(chen)由于不可能均勻地(di)附著(zhu)在(zai)葉(xie)(xie)輪(lun)(lun)上，而造(zao)成葉(xie)(xie)輪(lun)(lun)平(ping)衡(heng)破壞，以至(zhi)引起轉子振動(dong)(dong)。葉(xie)(xie)輪(lun)(lun)只(zhi)要(yao)(yao)(yao)進行(xing)了(le)修(xiu)理(li)，就(jiu)需要(yao)(yao)(yao)對(dui)其(qi)再作(zuo)(zuo)動(dong)(dong)平(ping)衡(heng)。如有(you)條件(jian)，可以使用便攜試動(dong)(dong)平(ping)衡(heng)儀(yi)在(zai)現場進行(xing)平(ping)衡(heng)。在(zai)作(zuo)(zuo)動(dong)(dong)平(ping)衡(heng)之前(qian)，必(bi)(bi)須(xu)檢查所(suo)有(you)緊定螺(luo)栓是否上緊。因為葉(xie)(xie)輪(lun)(lun)已(yi)經在(zai)不平(ping)衡(heng)狀態(tai)下運行(xing)了(le)一段時間(jian)，這(zhe)些螺(luo)栓可能已(yi)經松動(dong)(dong)。
