上海閥盛(sheng)閥門(men)制造(zao)有限公司主要生產(chan)多(duo)(duo)(duo)(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸閥，可提供多(duo)(duo)(duo)(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸閥價(jia)格，多(duo)(duo)(duo)(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸閥說明書(shu)，多(duo)(duo)(duo)(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸閥實物圖，多(duo)(duo)(duo)(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸閥結構圖，多(duo)(duo)(duo)(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸閥外形尺(chi)寸，多(duo)(duo)(duo)(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸閥執行標準，多(duo)(duo)(duo)(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸閥工作(zuo)原理，多(duo)(duo)(duo)(duo)(duo)功(gong)(gong)能(neng)呼(hu)(hu)(hu)吸閥作(zuo)用特(te)點。

GFD/Q多功能阻火呼吸(xi)閥類(lei)似于單向止逆(ni)閥,它只能向外呼氣,不能向內(nei)吸(xi)氣,當系統(tong)內(nei)壓(ya)(ya)力升高時,氣體便經(jing)過(guo)向外放空,保證(zheng)系統(tong)的壓(ya)(ya)力恒(heng)定。一(yi)般它被用在常壓(ya)(ya)或低壓(ya)(ya)貯罐上。

焦炭(tan)塔(ta)(ta)的呼吸閥有(you)兩個(ge)用(yong)處：放(fang)水(shui)時吸氣(qi)(qi)以(yi)利(li)塔(ta)(ta)內存(cun)水(shui)順(shun)利(li)放(fang)出,呼氣(qi)(qi)蒸汽趕空氣(qi)(qi)時,用(yong)以(yi)放(fang)凈空氣(qi)(qi),脫水(shui)放(fang)汽時,用(yong)以(yi)檢查塔(ta)(ta)內是(shi)否為正壓。

GFD/Q多功能呼吸閥閥體的材質有:鑄鐵(tie)、鑄鋼、不銹鋼、鋁合(he)金。工作(zuo)壓力0.6-6.4MPA，工作(zuo)溫度-20°C-425C°。閥門(men)口(kou)徑從 DN15-DN300。連接方(fang)式:法蘭、對夾、絲口(kou)或焊(han)接。

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

多功能呼吸閥適用(yong)介質:水、油品、氣、蒸汽。主(zhu)要領域：化工設(she)備(bei)、通用(yong)零(ling)部(bu)件、工業設(she)備(bei)、制藥設(she)備(bei)、通用(yong)設(she)備(bei)、石化設(she)備(bei)。
