1. The warm air valve is located between the main water tank of the steam turbine and the warm air water tank. You can identify it along the outlet of the heater box connected to the main air inlet of the engine. The warm air valve is the warm air switch of the electric vehicle heater. The warm air working principle of electric vehicle heater is that the fan in the heater is connected with the circulating water phase of the engine through the combustion chamber. The water valve is closed, the waterway is disconnected, the turbine circulating water enters the water tank, and the compressor blows energy into the seating room.
2. The valve body maintenance center has a valve stem. The valve stem is bent outside the valve body, and the end of the bent part is sleeved with a disk of a melt bag. The valve stem fluctuates but slides with the vacuum degree of the melt container. Water heating and warm air system is mostly used in cars, large trucks and buses with low peak shift indication.
