When the coolant flows into the connecting tube, the heat of the coolant will be transferred to the heat-conducting member 6.

When the motor 12 starts the rotating column 11 to rotate, the rotating column 11 can drive the valve plate 2 to swing, so that the closed part of the valve plate 2 can close the valve body 1. When the valve plate 2 swings, the sealing ring 9 can always be in close contact with the valve plate 2 under the push of the elastic member 10, thereby improving the sealing of the valve body 1, and when the valve plate 2 swings, the strong spring 16 can push the top member 14 to support the valve plate 2, thereby reducing the load of the motor 12.
