放(fang)風閥廣泛(fan)應用于建(jian)材、冶金、石(shi)化、電力等(deng)行業的高(gao)爐🈲系統的(de)冷風和空(kong)氣管道。該(gai)閥可在不(bu)停止鼓風(feng)機工作的(de)情況下減(jian)少或完全(quan)停止向高(gao)爐送氣，将(jiang)多餘的氣(qi)體從管道(dao)💞中排入大(da)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..

結構特(te)點：

Structure characteristic:

  放風閥(fa)由閥體、蝶(die)闆、連杆、排(pai)風筒等零(ling)件組成。手(shou)動放風閥(fa)🏃由杠杆機(ji)構轉動蝶(die)闆實現閥(fa)門啟閉，自(zi)動放風閥(fa)由自動裝(zhuang)置驅動蝶(die)闆，可實現(xian)遠距離控(kong)制閥門的(de)啟閉，完成(cheng)氣體的排(pai)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.
