上海閥(fa)盛閥(fa)門制造有限公司主要生產多(duo)功(gong)(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)(hu)(hu)吸(xi)(xi)閥(fa)，可提供多(duo)功(gong)(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)(hu)(hu)吸(xi)(xi)閥(fa)價(jia)格，多(duo)功(gong)(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)(hu)(hu)吸(xi)(xi)閥(fa)說明書，多(duo)功(gong)(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)(hu)(hu)吸(xi)(xi)閥(fa)實物圖(tu)，多(duo)功(gong)(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)(hu)(hu)吸(xi)(xi)閥(fa)結構(gou)圖(tu)，多(duo)功(gong)(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)(hu)(hu)吸(xi)(xi)閥(fa)外形尺寸，多(duo)功(gong)(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)(hu)(hu)吸(xi)(xi)閥(fa)執行(xing)標準，多(duo)功(gong)(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)(hu)(hu)吸(xi)(xi)閥(fa)工(gong)作(zuo)原理(li)，多(duo)功(gong)(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)(hu)(hu)吸(xi)(xi)閥(fa)作(zuo)用特點。

GFD/Q多(duo)功能(neng)阻火呼吸閥類似于單向止逆閥,它只(zhi)能(neng)向外(wai)呼氣(qi),不能(neng)向內吸氣(qi),當系(xi)統(tong)(tong)內壓(ya)力升(sheng)高時,氣(qi)體便(bian)經過向外(wai)放空,保證系(xi)統(tong)(tong)的壓(ya)力恒(heng)定。一般它被(bei)用在常壓(ya)或(huo)低壓(ya)貯(zhu)罐上。

焦炭塔(ta)的(de)呼吸閥(fa)有兩個用(yong)處：放(fang)水時吸氣(qi)以利塔(ta)內存(cun)水順(shun)利放(fang)出,呼氣(qi)蒸汽趕(gan)空氣(qi)時,用(yong)以放(fang)凈空氣(qi),脫(tuo)水放(fang)汽時,用(yong)以檢查塔(ta)內是否(fou)為(wei)正壓。

GFD/Q多(duo)功能呼吸閥閥體的(de)材質有:鑄鐵、鑄鋼(gang)(gang)、不銹鋼(gang)(gang)、鋁合(he)金(jin)。工(gong)作壓力0.6-6.4MPA，工(gong)作溫度-20°C-425C°。閥門口(kou)徑(jing)從 DN15-DN300。連接(jie)方(fang)式:法蘭、對夾、絲口(kou)或焊接(jie)。

驅動(dong)方式:手動(dong)、蝸輪、氣動(dong)、電動(dong)。

多功能呼吸閥(fa)適(shi)用(yong)介質:水、油品、氣、蒸汽。主(zhu)要領(ling)域：化工設(she)(she)備(bei)(bei)(bei)、通(tong)用(yong)零部件、工業設(she)(she)備(bei)(bei)(bei)、制(zhi)藥設(she)(she)備(bei)(bei)(bei)、通(tong)用(yong)設(she)(she)備(bei)(bei)(bei)、石化設(she)(she)備(bei)(bei)(bei)。
