In addition, the oil temperature cannot be stabilized, which prevents lubrication points such as gearboxes and bearings from being properly lubricated. Utility Model Content

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] like Figure 1 、 Figure 2 、 Figure 4 The temperature control valve structure shown mainly includes a push rod 1, a valve body 2, a return spring 3, a corrugated spring 4 and a temperature-sensing package 5. The corrugated spring 4 and the temperature-sensing package 5 are installed in the hollow inner cavity of the valve body 2. The cross-section of the push rod 1 is an I-shaped structure, and the corrugated spring 4 is sleeved on the push rod 1. The valve body 2 is provided with a plurality of through holes 6, and the plurality of through holes 6 are distributed on the circumference of the same radius, such as Figure 3As shown. The temperature-sensing package 5 preferably adopts a cylindrical structure, and the temperature-sensing package 5 is a paraffin temperature-sensing package formed by filling paraffin. Usually, paraffin is filled in a stainless steel shell with a cylindrical structure as a temperature-sensing material, and is sealed by threaded fastening and polytetrafluoroethylene gaskets to prevent paraffin leakage. The temperature controlled by the temperature-sensing package is confirmed by calculating the expansion amount of the paraffin filling amount to the position of the valve body 2. Therefore, the temperature control range of the temperature-sensing package 5 is directly related to the filling amount of paraffin. The use of this paraffin temperature-sensing package has a high sensitivity to temperature changes and can meet different temperature design ranges, thereby meeting customized design requirements. The material of the reset spring 3 is selected to be 65Mn, so that the pressure of the temperature control valve system can be stabilized at 0.5~0.6MPa.

[0019] The temperature-sensing bulb 5 is connected to the push rod 1. Typically, the push rod 1 and the temperature-sensing bulb 5 form an integrated package structure to prevent the paraffin wax in the temperature-sensing bulb 5 from leaking, ensuring that the temperature-controlled valve is leak-free. The push rod 1 can move linearly relative to the valve body 2. Specifically, when the temperature-sensing bulb 5 expands due to heat, the bulb drives the push rod 1 to extend linearly relative to the valve body 2. When the temperature of the temperature-sensing bulb 5 drops, the push rod 1, driven by the corrugated spring 4, retracts linearly relative to the valve body 2 until it returns to its original position.

[0020] The temperature control valve of the present invention can be applied to lubricating oil systems to make their operation more stable, and the temperature of the lubricating oil is controlled within a range of 35 to 55°C. The temperature-sensing bulb 5 is in direct contact with the lubricating oil, and its temperature control range is 35 to 55°C as the temperature changes. When the temperature-sensing bulb 5 expands due to heat, it drives the push rod 1 upward, which in turn pushes the valve body 2 to move, thereby switching the lubricating oil channel. When the temperature drops, the corrugated spring 4 resets the push rod 1, and the valve body 2 also returns to its original position under the action of the return spring 3. The corrugated spring 4 cooperates with the return spring 3 to push the valve body 2 to move, thereby switching the flow direction of the oil.

[0021] When the temperature is low, the lubricating oil can be diverted directly to lubrication points such as the gearbox and bearings. When the temperature is high, the lubricating oil can be diverted directly to the cooling unit, allowing the lubricating oil to be cooled accordingly, thereby ensuring better lubrication. Specifically, the lubricating oil flows into the temperature control valve. When the temperature is below 35°C, the temperature control valve does not operate, and the lubricating oil flows entirely from the gearbox oil port. When the temperature is between 35°C and 55°C, the temperature control valve operates to varying degrees, allowing the lubricating oil to flow from the gearbox oil port and the cooler oil port respectively. When the temperature exceeds 55°C, the temperature control valve switches to the maximum position, allowing the lubricating oil to flow entirely from the cooler oil port.

[0022] The temperature control valve of the utility model has a compact structure and is easy to use and install. It can save 10%-15% of the installation space for the overall structural design of the lubrication system and reduce the overall weight of the temperature control valve group by 2KG. By adopting the corrugated spring 4 and the temperature sensing package 5, the temperature control valve has a high sensitivity to temperature response and can be independently designed according to the temperature control of different working conditions or working systems, which is convenient for designing different temperature ranges. In addition, this mechanical control structure is not easy to fail, has good fatigue resistance, is easy to maintain, has high stability, and has low maintenance costs, thereby significantly improving the service life of the temperature control valve and ensuring more stable operation of the lubrication system.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
