畢節值得信賴的不銹鋼通風管廠家

一(yi)、風(feng)(feng)管(guan)(guan)(guan)及(ji)(ji)部件安(an)裝(zhuang)(zhuang)(zhuang)(zhuang)的(de)(de)有(you)關規定(ding)1.風(feng)(feng)管(guan)(guan)(guan)安(an)裝(zhuang)(zhuang)(zhuang)(zhuang)的(de)(de)強制(zhi)規定(ding),當風(feng)(feng)管(guan)(guan)(guan)穿(chuan)過(guo)需要(yao)封閉的(de)(de)防(fang)火、防(fang)爆墻體(ti)或(huo)樓板(ban)時，應(ying)(ying)設預(yu)埋管(guan)(guan)(guan)或(huo)防(fang)護(hu)套(tao)管(guan)(guan)(guan)。套(tao)管(guan)(guan)(guan)鋼板(ban)厚度不(bu)應(ying)(ying)小(xiao)于1.6mm，風(feng)(feng)管(guan)(guan)(guan)與防(fang)護(hu)套(tao)管(guan)(guan)(guan)之(zhi)間應(ying)(ying)用不(bu)燃且對人體(ti)無害的(de)(de)柔性材料封堵，風(feng)(feng)道應(ying)(ying)安(an)裝(zhuang)(zhuang)(zhuang)(zhuang)設防(fang)火閥。風(feng)(feng)管(guan)(guan)(guan)內嚴禁各(ge)種管(guan)(guan)(guan)道、電線敷設及(ji)(ji)穿(chuan)越(yue)；輸(shu)送(song)含有(you)易(yi)燃易(yi)爆氣體(ti)或(huo)安(an)裝(zhuang)(zhuang)(zhuang)(zhuang)在易(yi)燃易(yi)爆環境的(de)(de)風(feng)(feng)管(guan)(guan)(guan)系統，應(ying)(ying)有(you)良好的(de)(de)接(jie)地(di)，通過(guo)生活區、生產房(fang)間時必須嚴密，不(bu)得設接(jie)口(kou)；室外(wai)主(zhu)管(guan)(guan)(guan)的(de)(de)固定(ding)拉索嚴禁拉在避雷針或(huo)避雷網(wang)上(shang)。輸(shu)送(song)溫(wen)度高(gao)于80℃的(de)(de)空(kong)氣的(de)(de)風(feng)(feng)管(guan)(guan)(guan)，應(ying)(ying)按(an)設計要(yao)求采取防(fang)護(hu)措施。2.風(feng)(feng)管(guan)(guan)(guan)安(an)裝(zhuang)(zhuang)(zhuang)(zhuang)的(de)(de)一(yi)般規定(ding)風(feng)(feng)管(guan)(guan)(guan)安(an)裝(zhuang)(zhuang)(zhuang)(zhuang)宜在建筑圍護(hu)結構(gou)施工完(wan)(wan)畢(bi)、場(chang)(chang)所清理(li)后進(jin)行。凈化(hua)空(kong)調風(feng)(feng)管(guan)(guan)(guan)應(ying)(ying)在安(an)裝(zhuang)(zhuang)(zhuang)(zhuang)部位(wei)地(di)面做好，墻面抹灰工序完(wan)(wan)畢(bi)，室內無飛(fei)塵(chen)或(huo)有(you)防(fang)塵(chen)措施后進(jin)行。安(an)裝(zhuang)(zhuang)(zhuang)(zhuang)風(feng)(feng)管(guan)(guan)(guan)前(qian)應(ying)(ying)清除管(guan)(guan)(guan)內外(wai)雜物，并做好清潔和(he)保護(hu)工作(zuo)，風(feng)(feng)管(guan)(guan)(guan)安(an)裝(zhuang)(zhuang)(zhuang)(zhuang)的(de)(de)位(wei)置(zhi)、標高(gao)和(he)走向等應(ying)(ying)符合(he)設計要(yao)求，現場(chang)(chang)風(feng)(feng)管(guan)(guan)(guan)接(jie)口(kou)的(de)(de)配置(zhi)不(bu)得縮小(xiao)有(you)效截面。

在空調(diao)送風(feng)(feng)系(xi)統中(zhong)(zhong)，空調(diao)送風(feng)(feng)機(ji)送出的風(feng)(feng)必須通過(guo)主(zhu)干(gan)管(guan)(guan)分配到(dao)支(zhi)管(guan)(guan)中(zhong)(zhong)；在排煙(yan)(yan)(yan)(yan)(yan)系(xi)統中(zhong)(zhong)，煙(yan)(yan)(yan)(yan)(yan)氣(qi)(qi)(qi)(qi)由(you)支(zhi)管(guan)(guan)到(dao)主(zhu)干(gan)管(guan)(guan)后，進入排煙(yan)(yan)(yan)(yan)(yan)風(feng)(feng)機(ji)排出。當建筑物內(nei)發(fa)生(sheng)火(huo)(huo)災(zai)時，在通風(feng)(feng)、空調(diao)系(xi)統中(zhong)(zhong)，為了(le)防(fang)止火(huo)(huo)勢(shi)通過(guo)送風(feng)(feng)系(xi)統蔓(man)延(yan)，當送風(feng)(feng)系(xi)統中(zhong)(zhong)氣(qi)(qi)(qi)(qi)體(ti)溫度(du)達(da)到(dao)70℃時，防(fang)火(huo)(huo)閥(fa)機(ji)構上(shang)熔斷器動(dong)(dong)作，閥(fa)門亦迅速關(guan)(guan)閥(fa)，切斷煙(yan)(yan)(yan)(yan)(yan)氣(qi)(qi)(qi)(qi)與火(huo)(huo)勢(shi)沿風(feng)(feng)管(guan)(guan)蔓(man)延(yan)的通路。同樣，在排煙(yan)(yan)(yan)(yan)(yan)系(xi)統中(zhong)(zhong)，發(fa)生(sheng)火(huo)(huo)災(zai)時，排煙(yan)(yan)(yan)(yan)(yan)閥(fa)開啟(qi)，進行排煙(yan)(yan)(yan)(yan)(yan)，為了(le)截斷高溫煙(yan)(yan)(yan)(yan)(yan)氣(qi)(qi)(qi)(qi)在排煙(yan)(yan)(yan)(yan)(yan)管(guan)(guan)路中(zhong)(zhong)流(liu)動(dong)(dong)，防(fang)止火(huo)(huo)勢(shi)蔓(man)延(yan)到(dao)另一(yi)防(fang)火(huo)(huo)分區，當排出的煙(yan)(yan)(yan)(yan)(yan)氣(qi)(qi)(qi)(qi)溫度(du)達(da)到(dao)280℃時，排煙(yan)(yan)(yan)(yan)(yan)防(fang)火(huo)(huo)閥(fa)、排煙(yan)(yan)(yan)(yan)(yan)口上(shang)熔斷器動(dong)(dong)作，閥(fa)門必須自動(dong)(dong)關(guan)(guan)閉，阻止排煙(yan)(yan)(yan)(yan)(yan)。由(you)此(ci)可見，防(fang)火(huo)(huo)閥(fa)、排煙(yan)(yan)(yan)(yan)(yan)閥(fa)做(zuo)到(dao)了(le)該通則通，該斷則斷的隔(ge)煙(yan)(yan)(yan)(yan)(yan)阻火(huo)(huo)作用(yong)。

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，市場上常見的值得信賴的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，不銹鋼通風管廠家在空調(diao)送回(hui)風(feng)(feng)(feng)干管(guan)(guan)，通風(feng)(feng)(feng)風(feng)(feng)(feng)機進出口(kou)(kou)，風(feng)(feng)(feng)井入(ru)(ru)口(kou)(kou)，管(guan)(guan)道(dao)穿越防(fang)火(huo)分區 / 變形縫 / 重要(yao)房(fang)間 / 機房(fang) / 火(huo)災危險性(xing)大的房(fang)間的隔墻(qiang)或(huo)樓板(ban)，垂直(zhi)風(feng)(feng)(feng)管(guan)(guan)與每層水(shui)(shui)平(ping)風(feng)(feng)(feng)管(guan)(guan)連接處。等很多(duo)場合都需要(yao)設(she)置(zhi)防(fang)火(huo)閥(fa)。 空調(diao)新風(feng)(feng)(feng)取風(feng)(feng)(feng)管(guan)(guan)是(shi)否需要(yao)安裝(zhuang)防(fang)火(huo)閥(fa)？一(yi)般(ban)不需要(yao)。特(te)別是(shi)如果回(hui)風(feng)(feng)(feng)、送風(feng)(feng)(feng)均(jun)安裝(zhuang)防(fang)火(huo)閥(fa)之后，新風(feng)(feng)(feng)取風(feng)(feng)(feng)口(kou)(kou)就沒有必要(yao)在安裝(zhuang)防(fang)火(huo)閥(fa)了。并且一(yi)般(ban)取風(feng)(feng)(feng)口(kou)(kou)位于室外，且按照規范要(yao)求與排煙(yan)口(kou)(kou)保持10 m以上(shang)的水(shui)(shui)平(ping)距離或(huo)3 m以上(shang)的垂直(zhi)距離（ 排煙(yan)口(kou)(kou)在上(shang) ），一(yi)般(ban)煙(yan)氣(qi)不會從新風(feng)(feng)(feng)口(kou)(kou)進入(ru)(ru)空調(diao)，所以一(yi)般(ban)不需要(yao)安裝(zhuang)防(fang)火(huo)閥(fa)。

消防(fang)(fang)排煙(yan)(yan)(yan)(yan)機(ji)一(yi)般是采用(yong)離(li)心(xin)式(shi)(shi)風(feng)(feng)(feng)(feng)機(ji)和(he)軸(zhou)流(liu)(liu)(liu)式(shi)(shi)風(feng)(feng)(feng)(feng)機(ji)兩種(zhong)重(zhong)要(yao)的(de)(de)(de)型式(shi)(shi)。從消防(fang)(fang)排煙(yan)(yan)(yan)(yan)風(feng)(feng)(feng)(feng)機(ji)風(feng)(feng)(feng)(feng)量(liang)、風(feng)(feng)(feng)(feng)壓考慮(lv)來看，消防(fang)(fang)排煙(yan)(yan)(yan)(yan)風(feng)(feng)(feng)(feng)機(ji)是高(gao)(gao)比轉(zhuan)高(gao)(gao)效率(lv)的(de)(de)(de)風(feng)(feng)(feng)(feng)機(ji)，更加的(de)(de)(de)適合選用(yong)軸(zhou)流(liu)(liu)(liu)風(feng)(feng)(feng)(feng)機(ji)。軸(zhou)流(liu)(liu)(liu)式(shi)(shi)消防(fang)(fang)排煙(yan)(yan)(yan)(yan)風(feng)(feng)(feng)(feng)機(ji)有兩種(zhong)設計型式(shi)(shi)，一(yi)種(zhong)為(wei)(wei)電(dian)機(ji)與主氣(qi)流(liu)(liu)(liu)分離(li)型式(shi)(shi)，另(ling)(ling)一(yi)種(zhong)為(wei)(wei)電(dian)機(ji)置(zhi)于(yu)(yu)主氣(qi)流(liu)(liu)(liu)之(zhi)中(zhong)。根(gen)據(ju)煙(yan)(yan)(yan)(yan)氣(qi)溫(wen)(wen)度(du)的(de)(de)(de)不(bu)同，采用(yong)不(bu)同型式(shi)(shi)的(de)(de)(de)消防(fang)(fang)排煙(yan)(yan)(yan)(yan)風(feng)(feng)(feng)(feng)機(ji)，溫(wen)(wen)度(du)大于(yu)(yu)400℃時(shi)，采用(yong)電(dian)機(ji)與主氣(qi)流(liu)(liu)(liu)分離(li)型式(shi)(shi)，溫(wen)(wen)度(du)小于(yu)(yu)400℃大于(yu)(yu)150℃，兩種(zhong)型式(shi)(shi)的(de)(de)(de)電(dian)機(ji)都可(ke)(ke)以(yi)選擇，在溫(wen)(wen)度(du)小于(yu)(yu)150℃的(de)(de)(de)時(shi)候，采用(yong)電(dian)機(ji)置(zhi)于(yu)(yu)主氣(qi)流(liu)(liu)(liu)之(zhi)中(zhong)。 軸(zhou)流(liu)(liu)(liu)消防(fang)(fang)排煙(yan)(yan)(yan)(yan)風(feng)(feng)(feng)(feng)機(ji)的(de)(de)(de)流(liu)(liu)(liu)量(liang)范(fan)圍從7200m？/h至110000m？/h，有不(bu)同型號的(de)(de)(de)編(bian)制，用(yong)來滿足(zu)不(bu)同通風(feng)(feng)(feng)(feng)排煙(yan)(yan)(yan)(yan)流(liu)(liu)(liu)量(liang)的(de)(de)(de)需求(qiu)。消防(fang)(fang)排煙(yan)(yan)(yan)(yan)風(feng)(feng)(feng)(feng)機(ji)可(ke)(ke)以(yi)根(gen)據(ju)壓力情況的(de)(de)(de)不(bu)同分為(wei)(wei)兩種(zhong)類型，一(yi)類為(wei)(wei)軸(zhou)流(liu)(liu)(liu)式(shi)(shi)消防(fang)(fang)排煙(yan)(yan)(yan)(yan)機(ji)，其各(ge)機(ji)號的(de)(de)(de)壓力在600Pa左(zuo)右，另(ling)(ling)一(yi)類為(wei)(wei)斜(xie)流(liu)(liu)(liu)消防(fang)(fang)排煙(yan)(yan)(yan)(yan)風(feng)(feng)(feng)(feng)機(ji)，各(ge)機(ji)號的(de)(de)(de)壓力在1000Pa左(zuo)右。為(wei)(wei)了滿足(zu)排煙(yan)(yan)(yan)(yan)量(liang)和(he)通風(feng)(feng)(feng)(feng)換氣(qi)的(de)(de)(de)要(yao)求(qiu)，消防(fang)(fang)排煙(yan)(yan)(yan)(yan)風(feng)(feng)(feng)(feng)機(ji)一(yi)般都設計了雙速(su)型的(de)(de)(de)結(jie)構模(mo)式(shi)(shi)。低(di)速(su)可(ke)(ke)以(yi)通風(feng)(feng)(feng)(feng)使用(yong)，高(gao)(gao)速(su)可(ke)(ke)以(yi)排放煙(yan)(yan)(yan)(yan)霧，這樣不(bu)但可(ke)(ke)以(yi)節(jie)約能(neng)源(yuan)同時(shi)又降(jiang)低(di)了噪聲污染。

現(xian)階段是很(hen)多(duo)雞(ji)(ji)舍(she)都配備(bei)了通(tong)風(feng)(feng)(feng)(feng)(feng)(feng)管，我是2013年開(kai)始(shi)用(yong)(yong)(yong)的(de)通(tong)風(feng)(feng)(feng)(feng)(feng)(feng)管，在(zai)使用(yong)(yong)(yong)過程中(zhong)，曾經出現(xian)過很(hen)多(duo)問題(ti)(ti)，現(xian)總結一(yi)下，歡(huan)迎(ying)拍磚交(jiao)流。一(yi)，通(tong)風(feng)(feng)(feng)(feng)(feng)(feng)管的(de)作(zuo)用(yong)(yong)(yong)。1降低(di)操作(zuo)負壓(ya)。冬季沒安(an)裝通(tong)風(feng)(feng)(feng)(feng)(feng)(feng)管的(de)雞(ji)(ji)舍(she)，使用(yong)(yong)(yong)小(xiao)窗通(tong)風(feng)(feng)(feng)(feng)(feng)(feng)，尤其是跨度大的(de)雞(ji)(ji)舍(she)為了導風(feng)(feng)(feng)(feng)(feng)(feng)合理(li)安(an)全(quan)，使用(yong)(yong)(yong)高負壓(ya)通(tong)風(feng)(feng)(feng)(feng)(feng)(feng)。而使用(yong)(yong)(yong)通(tong)風(feng)(feng)(feng)(feng)(feng)(feng)管道(dao)，由于進風(feng)(feng)(feng)(feng)(feng)(feng)在(zai)管道(dao)內(nei)(nei)基本不(bu)擴散，低(di)負壓(ya)下都是按照風(feng)(feng)(feng)(feng)(feng)(feng)管方向(xiang)，依次從開(kai)口處出風(feng)(feng)(feng)(feng)(feng)(feng)。2位置(zhi)高，出風(feng)(feng)(feng)(feng)(feng)(feng)均勻。進風(feng)(feng)(feng)(feng)(feng)(feng)雖然在(zai)管道(dao)內(nei)(nei)沒有預熱，但下落位置(zhi)高，向(xiang)下擴散時(shi)間就(jiu)是預熱過程。3跟風(feng)(feng)(feng)(feng)(feng)(feng)機配合合理(li)配置(zhi)，在(zai)初始(shi)開(kai)啟風(feng)(feng)(feng)(feng)(feng)(feng)機階段，由于設計問題(ti)(ti)導致(zhi)進風(feng)(feng)(feng)(feng)(feng)(feng)窗使用(yong)(yong)(yong)不(bu)安(an)全(quan)，可(ke)以利(li)用(yong)(yong)(yong)通(tong)風(feng)(feng)(feng)(feng)(feng)(feng)管過渡(du)。
