Description

Thermostat structure for high system pressure

Technical Field

Background

The structure of the existing thermostat is shown in fig. 1, and comprises a cover body, an inductor, a push rod, a valve, a spring and the like, wherein the push rod and the inductor are distributed on two sides of the valve. When the valve is closed, the temperature regulator is stressed and balanced, the force born by one side of the temperature regulator is the system water pressure and the initial spring force, and the other side of the temperature regulator bears the acting force generated by the cover body and the push rod, and the acting force are equal. In high pressure systems, the push rod force of the enclosure is also greater due to the greater system water pressure, resulting in greater sensor internal pressure. After the valve is opened, the system water pressure is rapidly reduced, but the pressure in the sensor is not released quickly, the temperature regulator can be subjected to unbalanced stress, so that the operation is not smooth in the opening process, fluctuation occurs, and even the engine shakes when serious.
