Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the spring of the thermostat in the prior art has a relatively low service life, the structural design requirements of the thermostat are relatively high, and the gap between the retaining ring and the thermal element causes a relatively large leakage of the actual fluid. Defects Provide a thermostat for a heat exchange circuit

[0025] The orientation nouns such as top, bottom, left, and right described in the present invention are all described according to the relationship between up, down, left, and right in the accompanying drawings;

[0026] The initial deformation force of the first spring 203 in the present invention means that when the first spring 203 is compressed and deformed by the pressure of the push rod 205 so that the retaining ring 121 no longer bears the pressure exerted by the first spring 203, the first spring 203 under pressure.

[0027] The above definitions are applicable in all statements herein, and will not be repeated hereafter.

[0028] Such as Figure 1-Figure 5 As shown, in the thermostat embodiment of the present invention: the thermostat includes a valve body 102 provided with a cavity 112 and a thermodynamic element fitted in the cavity 112, and the thermodynamic element includes a thermosensitive substance The body and the push rod 205 slidingly installed on the fir...

Abstract

The invention relates to a thermostat for a heat exchange circuit, which includes a valve body provided with a cavity and a thermodynamic element matched and installed in the cavity, and the valve body also includes two valves respectively communicated with the cavity. A through hole: a first hole and a second hole, the first ends of the second hole and the first hole communicate with the inlet and outlet of the external fluid cooling device respectively, the second hole and the second end of the first hole are fluid inlet and fluid outlet respectively, the inner diameter of the cavity is larger than the inner diameter of the second hole and communicates with it, the end of the cavity close to the second hole partially overlaps with the second hole, the heat An elastic component is sheathed on the outer peripheral side of the power element, one end of the elastic component is pressed against the thermal power element, and the other end of the elastic component is in contact with the shoulder formed by the bottom of the cavity and the second hole Compress the abutment. The thermostat used in the heat exchange circuit controls the working temperature of the lubricating oil in an effective range, and keeps the lubricating performance of the lubricating oil in the best state.

Description

technical field [0001] The invention relates to the mechanical field, and more specifically, relates to a thermostat for a heat exchange circuit. Background technique [0002] During the driving process of the car, lubricating oil needs to be replenished in time to ensure the normal operation of the car. If the lubrication performance of the lubricating oil is not good enough, it will greatly reduce the service life of the car and even cause a car accident. The lubricating performance of lubricating oil is closely related to its own temperature. When the temperature of lubricating oil is too high or too low, the lubricating oil will lose its lubricating performance. [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 gea...
