風道內套

注(zhu)意油煙機安裝的位(wei)置(zhi)是很關鍵的，管道安裝的時候是越短越好的，因此在安裝之前(qian)就需要考慮到這些問題(ti)，避免(mian)管道過長影(ying)響使用。

注意(yi)樓房中想要安裝廚(chu)房排氣(qi)道，就需要提前與(yu)物(wu)(wu)業(ye)溝(gou)通(tong)，物(wu)(wu)業(ye)同意(yi)之后在施工。

注意安全，排煙管的(de)尾端(duan)一般使用的(de)是金(jin)屬材質(zhi)的(de)，在開洞的(de)時候如果洞開的(de)太大，這樣就會(hui)導致出現(xian)玻璃裂(lie)開、炸裂(lie)的(de)問題，很容(rong)易傷到人，因(yin)此需(xu)要注意這個問題。

風道內套概述

當進氣(qi)(qi)口煙(yan)氣(qi)(qi)排(pai)入煙(yan)道內(nei)(nei)時，會(hui)和(he)下(xia)層往(wang)上(shang)排(pai)的煙(yan)氣(qi)(qi)相(xiang)遇，嫁接內(nei)(nei)套多少錢，二(er)股氣(qi)(qi)流相(xiang)遇會(hui)形成渦(wo)(wo)流和(he)空氣(qi)(qi)幕，該(gai)渦(wo)(wo)流和(he)空氣(qi)(qi)阻滯幕會(hui)對下(xia)層煙(yan)氣(qi)(qi)上(shang)行(xing)產(chan)生阻礙，一旦防火止回閥(fa)被(bei)油污粘(zhan)住開啟失靈時，煙(yan)氣(qi)(qi)因上(shang)行(xing)有阻礙，便會(hui)向室(shi)內(nei)(nei)串煙(yan)。 

風道內套原理

當(dang)進(jin)(jin)風(feng)口煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)氣(qi)(qi)(qi)排進(jin)(jin)排煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)道內時，會(hui)和(he)(he)下(xia)一(yi)層往(wang)下(xia)排的(de)(de)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)氣(qi)(qi)(qi)相(xiang)逢(feng)，二股氣(qi)(qi)(qi)旋相(xiang)逢(feng)會(hui)產(chan)(chan)生(sheng)渦流(liu)(liu)(liu)和(he)(he)風(feng)幕(mu)機，該渦流(liu)(liu)(liu)和(he)(he)氣(qi)(qi)(qi)體阻礙幕(mu)會(hui)對下(xia)一(yi)層煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)氣(qi)(qi)(qi)上行造成阻攔，一(yi)旦防(fang)火止回閥被油(you)漬黏住(zhu)打開失效時，煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)氣(qi)(qi)(qi)因上行有(you)阻攔，便會(hui)向房間內串(chuan)(chuan)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)為了更(geng)好地擺(bai)脫之上串(chuan)(chuan)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)串(chuan)(chuan)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)的(de)(de)瓶頸問題，采用(yong)(yong)的(de)(de)解決方法是應用(yong)(yong)流(liu)(liu)(liu)體力學的(de)(de)聲(sheng)響壓(ya)變(bian)換原理(li)（伯(bo)努(nu)利定理(li)），由江蘇紫葳(wei)建(jian)筑工(gong)程技術研(yan)究(jiu)室產(chan)(chan)品(pin)研(yan)發的(de)(de)組成直流(liu)(liu)(liu)變(bian)壓(ya)器(qi)(qi)式(shi)防(fang)火廚房煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)道，在排煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)道內設(she)定拔氣(qi)(qi)(qi)和(he)(he)加快氣(qi)(qi)(qi)旋的(de)(de)直流(liu)(liu)(liu)變(bian)壓(ya)器(qi)(qi)止回預制構件(jian)促(cu)使煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)氣(qi)(qi)(qi)在特殊部位進(jin)(jin)行聲(sheng)響壓(ya)的(de)(de)變(bian)換，使不動排煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)系(xi)統機的(de)(de)餐廳廚房或洗手(shou)間出氣(qi)(qi)(qi)口處呈負壓(ya)力情況，并(bing)運用(yong)(yong)伯(bo)努(nu)利定理(li)的(de)(de)原理(li)，產(chan)(chan)生(sheng)吸力，進(jin)(jin)而(er)清(qing)除渦流(liu)(liu)(liu)和(he)(he)氣(qi)(qi)(qi)體阻礙幕(mu)，處理(li)廚房煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)道氣(qi)(qi)(qi)堵串(chuan)(chuan)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)狀況。該商品(pin)合理(li)地處理(li)汽體渦流(liu)(liu)(liu)、氣(qi)(qi)(qi)幕(mu)的(de)(de)阻礙和(he)(he)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)氣(qi)(qi)(qi)倒(dao)流(liu)(liu)(liu)與串(chuan)(chuan)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)串(chuan)(chuan)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)難題，可達(da)到(dao)住(zhu)房建(jian)設(she)工(gong)程要求，具備(bei)防(fang)串(chuan)(chuan)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)、防(fang)倒(dao)流(liu)(liu)(liu)、防(fang)火防(fang)火安全等作用(yong)(yong)。該成效被列入2012年全中國各地基本(ben)建(jian)設(she)領域科研(yan)成果營(ying)銷推廣新(xin)項(xiang)目。
