Problems solved by technology

[0005] However, in actual use, when the fluid pressure of the cooling oil is too high due to blockage of the external cooling device, etc., as the temperature of the cooling oil continues to rise, the channel through which the transmission oil directly flows back to the transmission is blocked , which will cause the fluid pressure of the gearbox cooling oil to be too high and the oil supply to be insufficient

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...

Abstract

The invention discloses a temperature regulation valve. A pressure releasing ring capable of moving up and down is arranged in a valve body cavity; the pressure releasing ring abuts against the outer edge of a first valve seat through a spring under the normal conditions; an inner channel opened or closed through upward movement and downward movement of the pressure releasing ring is also formed in the cavity; when the pressure of flow in the temperature regulation valve is excessively high, the flow can push the pressure releasing ring to compress the spring, so that the inner channel is connected with a third interface, and a first flow channel and a third flow channel are simultaneously connected; the damage caused by the excessively high pressure of the flow in the temperature regulation valve can be avoided.

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 ...
