風量調節閥在(zai)葉片(pian)(pian)寬度全統一(yi)為(wei)(wei)四種規格(ge)，葉片(pian)(pian)狀為(wei)(wei)菱形(xing)雙葉片(pian)(pian)，葉片(pian)(pian)間采用(yong)軟(ruan)搭接，因(yin)此(ci)密(mi)閉性能良好。 風量調節閥(fa)體構架用(yong)2毫米(mi)(mi)鍍(du)鋅板(ban)冷(leng)軋(ya)成(cheng)型(xing)后,以二(er)氧(yang)化碳氣(qi)體保護(hu)焊(han)(han)接或由(you)普通(tong)Q235板(ban)加工焊(han)(han)接而成(cheng)；葉片(pian)(pian)用(yong)1毫米(mi)(mi)鍍(du)鋅板(ban)冷(leng)軋(ya)為(wei)(wei)瓦(wa)楞形(xing)，兩片(pian)(pian)合(he)成(cheng)點(dian)焊(han)(han)插(cha)方軸，或2毫米(mi)(mi)G235鋼板(ban)冷(leng) 壓成(cheng)形(xing)，單片(pian)(pian)沖孔插(cha)方軸或焊(han)(han)圓(yuan)軸。 

       電動防火閥采用(yong)(yong)(yong)保溫風管板材(cai)(cai)，可(ke)在施工(gong)現(xian)場安(an)裝制作，只需要(yao)用(yong)(yong)(yong)簡單的專(zhuan)(zhuan)用(yong)(yong)(yong)刀具，切(qie)割、抹膠成型，用(yong)(yong)(yong)專(zhuan)(zhuan)用(yong)(yong)(yong)法蘭插件(jian)組合，最后用(yong)(yong)(yong)密封膠密封即可(ke)，吊裝用(yong)(yong)(yong)的鋼材(cai)(cai)及附(fu)件(jian)簡單、質輕，因(yin)此，用(yong)(yong)(yong)工(gong)少(shao)、進(jin)度快(kuai)，比傳統安(an)裝要(yao)快(kuai)2-3倍(bei)，節省(sheng)人(ren)工(gong)成本，也(ye)降低了施工(gong)危險。電動(dong)防火閥在使用(yong)(yong)(yong)過程中，任何一處有損壞，均可(ke)隨意(yi)進(jin)行(xing)切(qie)割粘接修補，維(wei)修相當方便。
