風帽的排煙效率

目(mu)前市場上的(de)(de)煙(yan)(yan)道風(feng)(feng)(feng)帽(mao)(mao)(mao)形式多樣，無(wu)論是(shi)(shi)(shi)傳統的(de)(de)的(de)(de)水泥風(feng)(feng)(feng)帽(mao)(mao)(mao)、還是(shi)(shi)(shi)無(wu)動力旋轉(zhuan)風(feng)(feng)(feng)帽(mao)(mao)(mao)、又(you)或(huo)者是(shi)(shi)(shi)百葉式風(feng)(feng)(feng)帽(mao)(mao)(mao)在生(sheng)活中已經很常見。而由萬居科技(ji)研發出來的(de)(de)變壓(ya)(ya)拔氣(qi)風(feng)(feng)(feng)帽(mao)(mao)(mao)再一次提升(sheng)了風(feng)(feng)(feng)帽(mao)(mao)(mao)這一產品的(de)(de)科技(ji)含(han)量和(he)排煙(yan)(yan)效果(guo)。不難相信在今后的(de)(de)某(mou)一天，我(wo)(wo)們的(de)(de)排煙(yan)(yan)系統能實(shi)時的(de)(de)將(jiang)煙(yan)(yan)道的(de)(de)排煙(yan)(yan)量、溫(wen)度(du)值(zhi)、風(feng)(feng)(feng)向、風(feng)(feng)(feng)壓(ya)(ya)、油(you)煙(yan)(yan)累(lei)計厚(hou)度(du)準確的(de)(de)顯(xian)示在你我(wo)(wo)的(de)(de)面前。那么說到(dao)變壓(ya)(ya)是(shi)(shi)(shi)拔氣(qi)風(feng)(feng)(feng)帽(mao)(mao)(mao)，它又(you)是(shi)(shi)(shi)什么原理來提高我(wo)(wo)們的(de)(de)排煙(yan)(yan)效率呢？

倒灌風帽的作用

本實用新型(xing)涉及一種通風(feng)(feng)(feng)排(pai)氣(qi)用防(fang)倒灌(guan)(guan)風(feng)(feng)(feng)帽，包(bao)括具有頂蓋的(de)(de)主(zhu)排(pai)風(feng)(feng)(feng)管和(he)支排(pai)風(feng)(feng)(feng)管，所述(shu)(shu)支排(pai)風(feng)(feng)(feng)管與所述(shu)(shu)主(zhu)排(pai)風(feng)(feng)(feng)管的(de)(de)上(shang)部開口相接(jie)并流體連通，并且(qie)所述(shu)(shu)支排(pai)風(feng)(feng)(feng)管沿所述(shu)(shu)主(zhu)排(pai)風(feng)(feng)(feng)管的(de)(de)徑向方向向下(xia)傾斜延伸，其中所述(shu)(shu)主(zhu)排(pai)風(feng)(feng)(feng)管的(de)(de)側壁在所述(shu)(shu)開口處向上(shang)延伸進入所述(shu)(shu)支排(pai)風(feng)(feng)(feng)管。本實用新型(xing)的(de)(de)防(fang)倒灌(guan)(guan)風(feng)(feng)(feng)帽具有簡單、緊湊、容(rong)易加工的(de)(de)結構，并且(qie)同(tong)時具有較(jiao)高(gao)的(de)(de)排(pai)風(feng)(feng)(feng)能力和(he)更好的(de)(de)防(fang)倒灌(guan)(guan)性能。

哪里需要安(an)裝防(fang)倒(dao)灌風帽

在(zai)樓房(fang)通(tong)(tong)(tong)風(feng)排氣(qi)通(tong)(tong)(tong)道(dao)頂(ding)(ding)(ding)部(bu)的(de)(de)出(chu)(chu)風(feng)口(kou)部(bu)位，通(tong)(tong)(tong)常要安裝(zhuang)防倒灌(guan)風(feng)帽，其結(jie) 構主要是在(zai)環繞通(tong)(tong)(tong)風(feng)道(dao)出(chu)(chu)口(kou)的(de)(de)托(tuo)板上(shang)，設有立(li)起的(de)(de)支撐柱(zhu)，在(zai)通(tong)(tong)(tong)風(feng)道(dao)出(chu)(chu)口(kou) 上(shang)方(fang)設有固定在(zai)支撐柱(zhu)上(shang)的(de)(de)頂(ding)(ding)(ding)蓋(gai)，頂(ding)(ding)(ding)蓋(gai)與(yu)(yu)托(tuo)板之(zhi)間形成水(shui)(shui)平氣(qi)流通(tong)(tong)(tong)道(dao)，水(shui)(shui)平 氣(qi)流通(tong)(tong)(tong)道(dao)里設有防倒灌(guan)導流體。這種結(jie)構的(de)(de)不足之(zhi)處是由于頂(ding)(ding)(ding)蓋(gai)與(yu)(yu)托(tuo)板之(zhi) 間的(de)(de)水(shui)(shui)平氣(qi)流通(tong)(tong)(tong)道(dao)周(zhou)圍均是開(kai)放式，大風(feng)或(huo)雨雪會隨氣(qi)流進入通(tong)(tong)(tong)道(dao)。 發明內容
