放風閥廣(guǎng)泛應用于(yu)建材、冶金(jīn)、石化、電力(li)等行業的(de)高爐系統(tǒng)的冷風和(hé)空氣管道(dao)。該閥可在(zai)不停止鼓(gu)風機工作(zuo)的情況下(xia)減少或完(wán)全停止向(xiang)高爐送氣(qì)，将多餘的(de)氣體從管(guǎn)道中排入(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..

結構(gou)特點：

Structure characteristic:

  放風(feng)閥由閥體(tǐ)、蝶闆、連杆(gǎn)、排風筒等(deng)零件組成(chéng)。手動放風(fēng)閥由杠🔱杆(gǎn)機構轉動(dong)蝶闆實現(xiàn)閥門啟閉(bi)，自動放風(feng)閥由自動(dong)裝置驅動(dòng)蝶闆，可實(shi)現遠距離(li)控制閥門(men)的啟閉，完(wan)🐅成氣體🤞的(de)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.
