放風(fēng)閥廣泛(fàn)應用于(yú)建材、冶(yě)金、石化(huà)、電力等(děng)行業的(de)高爐系(xi)統🏃的冷(leng)風和空(kōng)氣管道(dao)。該閥可(kě)在不停(ting)止鼓風(fēng)機工作(zuò)的情❌況(kuàng)下減少(shǎo)或完全(quan)停止向(xiang)高爐送(song)氣，将多(duō)餘♋的氣(qì)體👣從管(guan)道✌️中排(pái)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(tè)點：

Structure characteristic:

  放風(fēng)閥由閥(fa)體、蝶闆(pǎn)、連杆、排(pái)風筒等(deng)零件組(zu)成。手動(dong)放風閥(fa)由杠杆(gan)機構轉(zhuan)動蝶闆(pan)實現閥(fá)門啟閉(bì)，自動放(fàng)風閥由(you)自動裝(zhuāng)置驅動(dòng)蝶闆，可(kě)實現遠(yuǎn)距離控(kòng)制閥門(men)的啟閉(bi)，完成氣(qì)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.
