上(shang)海閥(fa)(fa)(fa)盛閥(fa)(fa)(fa)門制造有限(xian)公司主要生(sheng)產多(duo)(duo)功(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)吸(xi)(xi)閥(fa)(fa)(fa)，可提供(gong)多(duo)(duo)功(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)吸(xi)(xi)閥(fa)(fa)(fa)價格(ge)，多(duo)(duo)功(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)吸(xi)(xi)閥(fa)(fa)(fa)說明書(shu)，多(duo)(duo)功(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)吸(xi)(xi)閥(fa)(fa)(fa)實(shi)物圖，多(duo)(duo)功(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)吸(xi)(xi)閥(fa)(fa)(fa)結構圖，多(duo)(duo)功(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)吸(xi)(xi)閥(fa)(fa)(fa)外形(xing)尺寸，多(duo)(duo)功(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)吸(xi)(xi)閥(fa)(fa)(fa)執行(xing)標(biao)準，多(duo)(duo)功(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)吸(xi)(xi)閥(fa)(fa)(fa)工作原理，多(duo)(duo)功(gong)(gong)(gong)(gong)能(neng)(neng)呼(hu)吸(xi)(xi)閥(fa)(fa)(fa)作用特點(dian)。

GFD/Q多功能(neng)(neng)阻火呼吸(xi)閥類似于單向止逆閥,它只能(neng)(neng)向外(wai)呼氣(qi),不能(neng)(neng)向內吸(xi)氣(qi),當系(xi)(xi)統內壓(ya)(ya)(ya)(ya)力(li)升高(gao)時,氣(qi)體便經(jing)過向外(wai)放空,保證(zheng)系(xi)(xi)統的壓(ya)(ya)(ya)(ya)力(li)恒定。一(yi)般(ban)它被(bei)用(yong)在常壓(ya)(ya)(ya)(ya)或低壓(ya)(ya)(ya)(ya)貯罐上(shang)。

焦炭塔(ta)的呼吸閥有(you)兩個用(yong)(yong)處：放(fang)水時吸氣(qi)以(yi)利(li)塔(ta)內存水順利(li)放(fang)出,呼氣(qi)蒸汽趕(gan)空氣(qi)時,用(yong)(yong)以(yi)放(fang)凈空氣(qi),脫(tuo)水放(fang)汽時,用(yong)(yong)以(yi)檢查塔(ta)內是否(fou)為正壓。

GFD/Q多功能(neng)呼(hu)吸閥(fa)閥(fa)體的材質有:鑄(zhu)鐵、鑄(zhu)鋼、不(bu)銹(xiu)鋼、鋁合金。工作(zuo)壓(ya)力(li)0.6-6.4MPA，工作(zuo)溫度(du)-20°C-425C°。閥(fa)門口徑從 DN15-DN300。連接(jie)方(fang)式:法蘭、對(dui)夾、絲口或焊接(jie)。

驅(qu)動(dong)方式:手(shou)動(dong)、蝸輪、氣動(dong)、電動(dong)。

多功能呼吸閥(fa)適用介質(zhi):水、油品、氣、蒸汽。主要領域：化工設備(bei)(bei)、通用零部(bu)件、工業設備(bei)(bei)、制(zhi)藥(yao)設備(bei)(bei)、通用設備(bei)(bei)、石化設備(bei)(bei)。
