放風(fēng)閥廣泛(fan)應用于(yu)建材、冶(ye)金、石化(huà)、電力等(děng)行業的(de)高爐🔴系(xì)🐅統的冷(lěng)風和空(kong)氣管道(dao)。該閥可(kě)在不停(tíng)止鼓👄風(fēng)機工作(zuo)的情況(kuàng)下🔴減少(shao)或完全(quan)停止向(xiang)高爐送(song)氣，将多(duo)餘的氣(qi)體從管(guǎn)道中排(pai)入大氣(qì)。

  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(feng)閥由閥(fa)體、蝶闆(pan)、連杆、排(pái)風筒等(deng)零件組(zu)成。手動(dòng)放風閥(fá)由杠💯杆(gǎn)機構轉(zhuan)動蝶闆(pǎn)實現閥(fá)門啟閉(bì)，自動放(fàng)風閥由(you)自動裝(zhuāng)置驅動(dong)蝶闆，可(kě)實現遠(yuǎn)距離控(kong)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.
