上海閥(fa)盛閥(fa)門制造有限公司(si)主要(yao)生產多(duo)功(gong)(gong)(gong)能(neng)(neng)(neng)呼(hu)(hu)吸(xi)(xi)閥(fa)，可提供多(duo)功(gong)(gong)(gong)能(neng)(neng)(neng)呼(hu)(hu)吸(xi)(xi)閥(fa)價格(ge)，多(duo)功(gong)(gong)(gong)能(neng)(neng)(neng)呼(hu)(hu)吸(xi)(xi)閥(fa)說明書，多(duo)功(gong)(gong)(gong)能(neng)(neng)(neng)呼(hu)(hu)吸(xi)(xi)閥(fa)實物圖(tu)，多(duo)功(gong)(gong)(gong)能(neng)(neng)(neng)呼(hu)(hu)吸(xi)(xi)閥(fa)結(jie)構圖(tu)，多(duo)功(gong)(gong)(gong)能(neng)(neng)(neng)呼(hu)(hu)吸(xi)(xi)閥(fa)外(wai)形尺寸，多(duo)功(gong)(gong)(gong)能(neng)(neng)(neng)呼(hu)(hu)吸(xi)(xi)閥(fa)執行標(biao)準(zhun)，多(duo)功(gong)(gong)(gong)能(neng)(neng)(neng)呼(hu)(hu)吸(xi)(xi)閥(fa)工作原理，多(duo)功(gong)(gong)(gong)能(neng)(neng)(neng)呼(hu)(hu)吸(xi)(xi)閥(fa)作用特點。

GFD/Q多功能阻火呼(hu)吸(xi)(xi)閥類似于(yu)單向止逆(ni)閥,它(ta)只能向外(wai)呼(hu)氣,不能向內(nei)吸(xi)(xi)氣,當系(xi)統(tong)內(nei)壓(ya)力(li)升高時,氣體(ti)便經過(guo)向外(wai)放(fang)空,保證系(xi)統(tong)的壓(ya)力(li)恒定。一(yi)般它(ta)被(bei)用在(zai)常壓(ya)或低壓(ya)貯(zhu)罐上。

焦炭塔的呼(hu)吸閥(fa)有兩個用處：放水時(shi)吸氣(qi)以(yi)利塔內(nei)存水順利放出,呼(hu)氣(qi)蒸汽趕空氣(qi)時(shi),用以(yi)放凈空氣(qi),脫水放汽時(shi),用以(yi)檢查塔內(nei)是否為正壓。

GFD/Q多功能呼吸閥(fa)(fa)閥(fa)(fa)體的材(cai)質有:鑄鐵(tie)、鑄鋼(gang)、不(bu)銹(xiu)鋼(gang)、鋁合金。工作壓力0.6-6.4MPA，工作溫度-20°C-425C°。閥(fa)(fa)門口(kou)徑從 DN15-DN300。連接(jie)方式:法(fa)蘭、對夾、絲口(kou)或(huo)焊(han)接(jie)。

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

多功能呼吸(xi)閥適用介質:水、油(you)品(pin)、氣、蒸(zheng)汽。主(zhu)要領域：化工設備(bei)(bei)、通用零部件、工業設備(bei)(bei)、制藥(yao)設備(bei)(bei)、通用設備(bei)(bei)、石化設備(bei)(bei)。
