放風閥廣(guǎng)泛應用于建(jiàn)材、冶金、石化(hua)、電力等行業(ye)的高💚爐🐕系統(tǒng)的冷風和空(kōng)氣管道。該閥(fa)可在不停止(zhi)鼓風機工作(zuò)的情況下減(jiǎn)少或完全停(tíng)止向高爐送(sòng)氣，将多餘的(de)氣體從管道(dao)中排入大氣(qi)。

  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..

結構特點：

Structure characteristic:

  放(fang)風閥由閥體(tǐ)、蝶闆、連杆、排(pai)風筒等零件(jian)組成。手動♉放(fàng)風閥✌️由杠✂️杆(gan)機構轉動蝶(dié)闆實現閥門(men)啟閉，自動放(fang)風閥由自動(dòng)裝置驅動蝶(dié)闆，可實現遠(yuan)距離控制閥(fa)門的♈啟閉，完(wán)成氣體的排(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.
