放風(fēng)閥廣泛(fàn)應用于建材、冶金、石化、電力(lì)等(děng)行業的高(gāo)爐系統的冷風和空(kōng)氣管道。該閥可在不停止鼓風(fēng)機工作的(de)情況下減少或(huò)完全(quán)停止向(xiàng)高(gāo)爐送氣，将(jiāng)多餘的氣體從管道中排入大氣。

  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..

結構特(tè)點：

structure characteristic:

  放風閥由閥(fá)體、蝶闆、連杆、排(pái)風筒(tǒng)等零(líng)件組(zǔ)成。手(shǒu)動放風閥(fá)由杠(gàng)杆(gǎn)機(jī)構(gòu)轉動蝶闆實現閥門啟閉，自動放(fàng)風閥由自動裝(zhuāng)置驅(qū)動蝶闆，可(kě)實現(xiàn)遠距離控(kòng)制閥門(mén)的(de)啟閉，完成氣體的排(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.
