上海閥(fa)(fa)盛閥(fa)(fa)門制造有限公司(si)主(zhu)要(yao)生產多(duo)(duo)(duo)功(gong)(gong)能(neng)(neng)呼(hu)(hu)吸(xi)(xi)閥(fa)(fa)，可提供多(duo)(duo)(duo)功(gong)(gong)能(neng)(neng)呼(hu)(hu)吸(xi)(xi)閥(fa)(fa)價格，多(duo)(duo)(duo)功(gong)(gong)能(neng)(neng)呼(hu)(hu)吸(xi)(xi)閥(fa)(fa)說(shuo)明(ming)書，多(duo)(duo)(duo)功(gong)(gong)能(neng)(neng)呼(hu)(hu)吸(xi)(xi)閥(fa)(fa)實物圖，多(duo)(duo)(duo)功(gong)(gong)能(neng)(neng)呼(hu)(hu)吸(xi)(xi)閥(fa)(fa)結構圖，多(duo)(duo)(duo)功(gong)(gong)能(neng)(neng)呼(hu)(hu)吸(xi)(xi)閥(fa)(fa)外形尺寸，多(duo)(duo)(duo)功(gong)(gong)能(neng)(neng)呼(hu)(hu)吸(xi)(xi)閥(fa)(fa)執行標準，多(duo)(duo)(duo)功(gong)(gong)能(neng)(neng)呼(hu)(hu)吸(xi)(xi)閥(fa)(fa)工作原理，多(duo)(duo)(duo)功(gong)(gong)能(neng)(neng)呼(hu)(hu)吸(xi)(xi)閥(fa)(fa)作用特(te)點。

GFD/Q多功能(neng)阻(zu)火呼吸閥類(lei)似(si)于單向止逆(ni)閥,它只(zhi)能(neng)向外(wai)呼氣(qi),不(bu)能(neng)向內(nei)吸氣(qi),當系統內(nei)壓力升高時(shi),氣(qi)體便(bian)經過向外(wai)放空(kong),保證系統的壓力恒定。一般它被用在常壓或低壓貯(zhu)罐(guan)上。

焦炭塔(ta)的呼(hu)吸(xi)閥有兩個(ge)用處：放水時(shi)吸(xi)氣以利(li)塔(ta)內存水順利(li)放出,呼(hu)氣蒸(zheng)汽(qi)趕空氣時(shi),用以放凈空氣,脫水放汽(qi)時(shi),用以檢查塔(ta)內是(shi)否為(wei)正壓。

GFD/Q多功能呼吸閥(fa)閥(fa)體的材質有:鑄(zhu)鐵、鑄(zhu)鋼(gang)、不銹(xiu)鋼(gang)、鋁(lv)合金。工(gong)作壓力0.6-6.4MPA，工(gong)作溫度-20°C-425C°。閥(fa)門口徑從 DN15-DN300。連接方式:法蘭、對夾、絲口或焊接。

驅動方式:手動、蝸輪、氣(qi)動、電動。

多(duo)功能呼吸(xi)閥適用介質:水(shui)、油品、氣、蒸汽。主要(yao)領域：化(hua)工設備(bei)、通(tong)用零部件、工業設備(bei)、制藥(yao)設備(bei)、通(tong)用設備(bei)、石(shi)化(hua)設備(bei)。
