放風(fēng)閥廣泛應(yīng)用于建材、冶金、石化、電力等行業(yè)的高爐系統(tǒng)的冷風(fēng)和空氣管道。該閥可在不停止鼓風(fēng)機工作的情況下減少或停止向高爐送氣,將多余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(jié)構(gòu)特點:
Structure characteristic:
放風(fēng)閥由閥體、蝶板、連桿、排風(fēng)筒等零件組成。手動放風(fēng)閥由杠桿機構(gòu)轉(zhuǎn)動蝶板實現(xiàn)閥門啟閉,自動放風(fēng)閥由自動裝置驅(qū)動蝶板,可實現(xiàn)遠距離控制閥門的啟閉,完成氣體的排放。
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.
