What is the function of a car water valve

The function of the air conditioning heating water valve is to control the cooling and heating of the automotive air conditioning heating system. Specifically, when the temperature is high, the water valve is closed; When the temperature is low, the water valve opens to heat the car.

The function of a water valve in a car air conditioning heating system is a car air conditioning heating water valve used for cooling and heating control of the car air conditioning heating system, including a valve body, valve cover, valve plate, and vacuum capsule component; The vacuum capsule component is fixed to the valve body; The valve body adopts a four way pipeline structure, with drainage pipes, outlet pipes, and cold water inlet pipes arranged on it. The upper part is connected to a valve cover, which is connected to a warm water inlet pipe. The valve cover is sealed and fixed with the valve body; There is a valve stem located in the center of the valve body, and the part of the valve stem that extends out of the valve body is curved. The end of the curved part is connected to the connecting rod of the vacuum capsule component, and the valve stem rotates with the change of vacuum degree of the vacuum capsule; The valve stem is fixed with a valve plate, which is an oval shaped metal plate, and its shape and size match the inner wall of the valve body. It adjusts the cooling and heating of the water outlet with the rotation of the valve stem, playing a role in reversing the cooling and heating. The utility model has the characteristics of simple structure, easy processing, low cost, and reliable action, and can change the direction and position of the pipeline according to different installation positions.
