Thermolator and manufacture method of valve body of thermolator

Abstract

The invention relates to a manufacture method of a valve body of a thermolator. The manufacture method comprises a step of cutting a section bar with a cross section which is in a similar crossed shape into a valve body blank according to the size of the valve body, and a step of dividing the cross section of the section bar into three sections in the height direction, wherein the three sections comprise a widest middle section, a first section and a second section,wherein the first section and the second section are placed at two ends of the middle section. The width of the first section and the second section is smaller than the width of the middle section, the height of the first section is equal to or larger than 10.5mm, the width of the first section is in a range of 15.2mm and 21mm, and the height of the second section is equal to or larger than 6mm. The cut side face of the blank is a first side face. Two side faces, which are next to the first section and the second section, of the first side face are respectively a third side face and a second side face. The side face which is next to the third side face and the first section of the first side face is a fourth side face. Two fast connectors are processed on the third side face of the blank, and the height range of a first fast connector and a second fast connector is 4mm to 12mm.

Description

technical field [0001] The invention relates to the field of heat exchange, and more specifically, relates to a method for manufacturing a thermostat and a valve body thereof. 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 ...

AI Technical Summary

Problems solved by technology

In the prior art, the thermostat is connected to the parts to be lubricated through a quick joint. Since the quick joint and the valve body are sealed by an O-ring, there is a hidden danger of leakage.

In addition, because the joints need to be threaded, the valve body also needs to be threaded, which increases the cost.

Furthermore, the threads of the valve body are easily deformed during the welding process of the pipe, so that the quick connector cannot be screwed into the valve body

And in the prior art, the thermal expansion of the thermodynamic element inside the thermostat easily causes the compression of the second elastic element of the thermodynamic element so that the lubricant channel is blocked
