Abstract

The invention discloses a temperature regulating valve. A pressure relief ring which can move up and down is arranged in the cavity of the valve body. Under normal circumstances, the pressure relief ring is in contact with the outer edge of the first valve seat through a spring. The internal passage opened or closed by the pressure relief ring moving up and down. When the fluid pressure in the thermostat valve is too high, the fluid can push the pressure relief ring to compress the spring, so that the internal passage communicates with the third interface, realizing the first flow passage and the third flow passage. The flow channels are connected at the same time, which can prevent damage caused by excessive fluid pressure in the thermostat valve.

Description

technical field

[0001] The invention relates to the field of fluid control, in particular to a temperature regulating valve. Background technique

[0002] When the car is running, the parts need to be lubricated with lubricating oil in time to ensure the normal operation of the car. If the lubrication performance of the lubricating oil is not good enough, it will affect the service life of the car. The lubricating performance of the lubricating oil is closely related to its own temperature. When the temperature of the lubricating oil is too high or too low, the lubricating performance of the lubricating oil will be affected.

[0003] The temperature of the lubricating oil is generally not too high during normal driving. When the vehicle is overloaded or the four-wheel drive mode is set to drive on snow or off-road, the vehicle is driving under the condition of excessive slippage of the hydraulic torque converter, which may cause the gearbox to malfunction. Oil temperature ...

Embodiment Construction

[0028] The technical solution of the present invention provides a thermostat valve, by setting a pressure relief ring that can move under the action of pressure difference and spring restoring force in the cavity of the valve body, and also setting a pressure relief ring in the cavity that can move up and down through the pressure relief ring. Open or close the internal channel, under normal circumstances the pressure relief ring closes the internal channel, when the pressure difference between the two ends of the pressure relief ring is higher than the set value, the fluid can push the pressure relief ring to compress the spring, thereby opening the internal channel and realizing the first flow channel It communicates with the second flow channel at the same time, which can prevent damage caused by excessive fluid pressure in the system.

[0029] The initial deformation force mentioned in this manual refers to the pressure generated when the spring in the compressed state of t...
