放風閥(fá)廣泛應用于建(jian)材、冶金、石化、電(diàn)力等行業的高(gāo)爐系統的冷風(fēng)和空氣管道。該(gāi)閥可在不停止(zhi)鼓風機工作的(de)情況下減少或(huò)完全停止向高(gāo)爐送氣，将多餘(yu)的氣體從管道(dào)中排入大氣。

  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(jié)構特點：

Structure characteristic:

  放風閥(fa)由閥體、蝶闆、連(lián)杆、排風筒等零(líng)件組成。手動放(fang)風閥由杠杆機(ji)構轉動蝶闆實(shi)現閥門啟閉，自(zi)動放風💋閥由自(zì)動裝置驅動蝶(dié)闆，可實現遠距(ju)離控制閥門的(de)啟閉，完成氣體(ti)的排放。

  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.
