The warm air water valve is the warm air switch of the automobile heater. The working principle of the automobile heater is that the radiator in the heater is connected with the circulating water of the engine through the inlet and outlet water pipes, and the water valve is a switch. The water valve is opened, the waterway is connected, the circulating water of the engine enters the radiator, and the fan blows heat into the cab. On the contrary, the water valve is closed and the warm air doesn't work.
Matters needing attention
Don't open and close the valve on the heating pipe at will. If it is the first time to run the heating system, it usually needs debugging.
Specific operation method
1, adjust the position. Adjust the valve of each riser to a proper position.
2. Open the manual exhaust valve of each radiator to exhaust the air accumulated in the radiator, or open the exhaust valve of the gas collector installed at the top of the system to exhaust until each radiator heats up and the debugging is completed. Once the debugging is completed, the valve should be fixed and cannot be opened or closed at will.
3. Turn the handwheel clockwise when opening the valve, and counterclockwise when closing it, and rotate it in place according to the opening and closing instructions. Do not replace the radiator or drain water from the system at will. Without hot water, the water temperature in the pipe network will drop rapidly, resulting in a drop in indoor temperature.
4, such as valve failure, should immediately stop using, find out the reason and clear the fault.
