放風閥(fá)廣泛應(yīng)用于建(jian)材、冶金(jīn)、石化、電(diàn)力等行(hang)業的高(gāo)爐系統(tǒng)的冷風(fēng)和空氣(qì)管道。該(gāi)閥可在(zai)不停止(zhǐ)鼓風機(ji)工作的(de)情況下(xia)🏃減少或(huo)完全停(tíng)止向高(gāo)爐送氣(qì)，将多餘(yú)的氣體(ti)從管道(dào)中排入(rù)大氣。

  The valve is widely used at cold air pipe of blast furnace system in building material, metallurgy, oil, electric power industries etc. It can reduce or stop transmitting air to furnace without stopping fan and emit the otiose gas to the atmosphere through the pipe..

結(jie)構特點(dian)：

Structure characteristic:

  放風閥(fa)由閥體(tǐ)、蝶闆、連(lian)杆、排風(feng)筒等零(ling)件組成(chéng)。手動放(fàng)風閥由(you)杠杆機(ji)構轉動(dong)蝶闆實(shi)現閥門(mén)啟閉，自(zi)動放風(feng)閥由🈲自(zi)動裝置(zhi)驅動蝶(dié)闆，可實(shi)現遠距(ju)離控制(zhi)閥門的(de)啟閉，完(wán)成氣體(ti)的排放(fàng)。

  The valve is made up of body, disc, pole and discharging air cylinder etc. Manual valve realizes the open-close of gate by making the lever turning the butterfly disc. Electric valve realizes long- range control of open-close of gate to emit gas by making the electric device driving the butterfly disc.
