GFD/Q多功能阻(zu)火(huo)呼(hu)吸(xi)閥(fa)類似于單向(xiang)止逆閥(fa),它(ta)(ta)只(zhi)能向(xiang)外(wai)呼(hu)氣,不能向(xiang)內(nei)吸(xi)氣,當系(xi)統(tong)內(nei)壓力升高(gao)時,氣體便經過向(xiang)外(wai)放空,保證系(xi)統(tong)的(de)壓力恒定。一般它(ta)(ta)被用(yong)在(zai)常壓或低壓貯罐(guan)上(shang)。

焦炭塔的呼吸閥有兩個用處：放水(shui)時吸氣以(yi)利塔內存水(shui)順利放出,呼氣蒸汽(qi)趕(gan)空氣時,用以(yi)放凈(jing)空氣,脫(tuo)水(shui)放汽(qi)時,用以(yi)檢查塔內是否為正壓。

GFD/Q多(duo)功(gong)能(neng)呼(hu)吸閥(fa)閥(fa)體的材(cai)質有:鑄(zhu)鐵、鑄(zhu)鋼、不銹鋼、鋁合(he)金。工作壓力0.6-6.4MPA，工作溫度-20°C-425C°。閥(fa)門口徑從(cong) DN15-DN300。連接方式(shi):法蘭、對夾、絲口或焊接。

驅(qu)動(dong)方式:手動(dong)、蝸輪、氣(qi)動(dong)、電動(dong)。

多功能呼(hu)吸(xi)閥適用(yong)介質:水、油品、氣、蒸汽。主要領域(yu)：化工設(she)備、通用(yong)零部件、工業(ye)設(she)備、制藥(yao)設(she)備、通用(yong)設(she)備、石化設(she)備。
