The purpose of the warm air valve
The hot air valve is installed on the hot air pipeline of the blast furnace hot air stove system, which is a cut-off device used to control the opening and closing of the hot air stove during combustion and air supply. When installing the warm air valve, the wind direction arrow should point to the hot air main pipe; When the warm air valve is used as a combustion valve and the warm air valve is used as a return air door, the wind direction arrow should point to the hot air main pipe; When the warm air valve is used as a cut-off valve for mixed air, the wind direction arrow should face away from the main hot air pipeline.
