放風閥廣泛應用于建材、冶金、石(shí)化、電力等行業的高爐系統的冷風和空氣管道。該閥可在不停止鼓風機工作的情況下減(jiǎn)少(shǎo)或完全停止向高爐送氣，将多餘的氣體從(cóng)管道中排入大氣。

  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:

  放風閥由閥體、蝶(dié)闆、連杆、排風筒等零件組成。手動放風閥由杠杆機構轉動蝶闆實現閥門啟閉，自(zì)動放風閥由自動(dòng)裝置驅動蝶闆，可實現遠距離控制閥門的啟閉，完成(chéng)氣體的(de)排(pái)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.
