Description

Technical Field

[0001] This utility model relates to the field of temperature control valves, and more particularly to a temperature control valve that adjusts according to changes in fluid temperature. Background Technology

[0002] In various systems involving fluid transmission and control, especially oil circuit systems, precise control of fluid temperature is crucial.

[0003] Currently, common oil circuit control methods mainly rely on manual valves or simple mechanical devices. Manual valves require operators to adjust them manually based on experience and real-time monitoring data. This is not only cumbersome, but also difficult to adjust in a timely and accurate manner when temperatures fluctuate frequently, easily leading to excessively high or low oil temperatures, which affects the normal operation and service life of the equipment. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a temperature control valve that adjusts according to changes in fluid temperature, based on the current state of the technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a temperature control valve that adjusts according to the change of fluid temperature, including a valve sleeve and a temperature control valve disposed in the valve sleeve. The temperature control valve includes a temperature control valve seat and a first valve, a temperature sensing drive element, a first elastic element sleeved on the temperature sensing drive element, and a second valve disposed at the lower end of the temperature sensing drive element, arranged sequentially from top to bottom in the temperature control valve seat. The first valve has a through hole. The valve sleeve is divided into an upper cavity, a middle cavity and a lower cavity by a valve cover. The valve sleeve has a first liquid port communicating with the upper cavity, a liquid inlet communicating with the middle cavity and a second liquid port communicating with the lower cavity.

[0006] When the fluid temperature is too high, the temperature-sensing actuator expands due to heat and moves downward to block the lower cavity. The fluid flows from the inlet to the middle cavity, through the through hole into the upper cavity, and out through the first inlet. When the fluid temperature decreases, the temperature-sensing actuator cools and contracts. At the same time, the first elastic element drives the first valve to reset and block the upper cavity. The fluid flows from the inlet to the middle cavity, through the lower cavity, and out through the second inlet.

[0007] The aforementioned components achieve the following effect: by setting up a valve sleeve and a temperature control valve, and the temperature control valve including a temperature control valve seat, a first valve, a temperature-sensing actuator, a first elastic element, and a second valve, the temperature control valve seat divides the valve sleeve into an upper chamber, a middle chamber, and a lower chamber, and provides different liquid ports connected to them. This allows the temperature control valve to adjust the oil circuit according to the fluid temperature, eliminating the need for frequent manual intervention. It can respond to temperature changes more accurately and efficiently, greatly improving stability and reliability, and effectively meeting the oil circuit adjustment needs of various equipment.

[0008] Preferably, the temperature control valve seat includes a valve frame, a sealing seat disposed at the lower end of the valve frame for sealing the valve sleeve, a first valve ring disposed on the valve frame for sealing the first valve, and a second valve ring disposed on the valve frame for sealing the second valve, wherein a plurality of sealing rings are arranged on the sealing seat.

[0009] The effects achieved by the above components are as follows: By setting the temperature control valve seat, including the valve frame, sealing seat, first valve ring, and second valve ring, the valve frame provides a stable support structure for the entire temperature control valve, ensuring that all components are installed securely; the several sealing rings arranged on the sealing seat significantly enhance the sealing performance of the valve sleeve, effectively preventing oil leakage, avoiding resource waste, environmental pollution, and equipment failure caused by leakage, and reducing maintenance costs; the first valve ring and the second valve ring provide precise positioning and sealing positions for the first and second valves, respectively, better dividing the valve sleeve into the upper cavity, middle cavity, and lower cavity, making the valve action more precise and reliable, thereby improving the overall control accuracy of the temperature control valve.

[0010] Preferably, the temperature-sensing drive component includes a temperature-sensing wax, a temperature-sensing push block, and a push rod passing through the temperature-sensing push block, wherein the temperature-sensing wax is arranged between the temperature-sensing push block and the push rod.

[0011] The aforementioned components achieve the following effect: The temperature-sensing actuator, comprising a temperature-sensing wax, a temperature-sensing push block, and a push rod, utilizes the extreme sensitivity of the temperature-sensing wax to temperature changes to quickly and accurately detect fluctuations in fluid temperature. Once the temperature changes, the temperature-sensing wax expands or contracts, precisely actuating the temperature-sensing push block and push rod, thereby causing the valve to adjust accordingly and achieving precise regulation of the oil circuit. This results in a more sensitive temperature response and higher adjustment accuracy, meeting the stringent requirements for precise oil temperature control.

[0012] Preferably, the first valve ring is provided with a limiting snap ring that contacts and connects with the first valve.

[0013] The aforementioned components achieve the following effect: A limiting snap ring, located within the first valve ring and contacting the first valve, precisely limits the valve's range of motion. This not only ensures accurate valve movement within its specified stroke, preventing sealing defects or control errors due to excessive movement, but also further improves the stability and repeatability of valve operation. This limiting design ensures that the temperature control valve maintains high precision in controlling the oil circuit throughout long-term use, enhancing the overall reliability and durability of the temperature control valve.

[0014] Preferably, a sealing gasket is provided on the second valve along the lower end of the temperature-sensing push block.

[0015] The aforementioned components achieve the following effect: by installing a sealing gasket along the lower end of the temperature-sensing push block at the second valve, the sealing effect at the second valve is further enhanced. Even under high pressure or complex operating conditions, fluid leakage from the second valve can be effectively prevented, ensuring precise switching of the oil circuit and improving the accuracy of the temperature control valve's control over the oil circuit. Good sealing performance helps maintain stable system pressure, ensuring normal equipment operation, while reducing a series of problems that may be caused by leakage, such as reduced efficiency and equipment damage.

[0016] Preferably, a second elastic element is arranged in the lower cavity to contact and connect with the second valve.

[0017] The aforementioned components achieve the following effect: a second elastic element, arranged in the lower cavity and connected to the second valve, provides reliable assistance for the valve's reset. When the temperature changes, the second elastic element responds synchronously with the first elastic element, assisting the second valve to return to its initial position or adjust to the appropriate position according to the temperature, greatly improving the response speed and reliability of the temperature control valve. This ensures that the temperature control valve can still stably and quickly adjust the oil circuit when facing frequent temperature fluctuations, meeting the equipment's requirements for rapid oil temperature response control.

[0018] Compared with existing technologies, the advantages of this invention are as follows: By setting a valve sleeve and a temperature control valve, a temperature-sensing and regulating oil circuit is realized, greatly improving stability and reliability and reducing manual intervention. The temperature control valve seat provides support, sealing, and valve positioning, effectively preventing leakage and improving control accuracy. The temperature-sensing actuator responds sensitively to temperature changes and can precisely adjust the oil circuit. The valve's limit, sealing, and reset auxiliary designs further optimize the performance of the temperature control valve in terms of accuracy, sealing, and response speed.

[0029] In this embodiment 1,

[0030] like Figures 1 to 4 As shown, this utility model provides a temperature control valve that adjusts according to changes in fluid temperature, including a valve sleeve 1 and a temperature control valve 2 disposed within the valve sleeve 1. The temperature control valve 2 includes a temperature control valve seat 3 and a first valve 4, a temperature sensing actuator 5, a first elastic member 6 sleeved on the temperature sensing actuator 5, and a second valve 7 disposed at the lower end of the temperature sensing actuator 5, arranged sequentially from top to bottom within the temperature control valve seat 3. The first valve 4 has a through hole 8. The valve sleeve 1 is divided into an upper cavity 9, a middle cavity 10, and a lower cavity 11 by a valve cover. The valve sleeve 1 has a first liquid port 12 communicating with the upper cavity 9, a liquid inlet 13 communicating with the middle cavity 10, and a second liquid port 14 communicating with the lower cavity 11.

[0031] When the fluid temperature is too high, the temperature-sensing actuator 5 expands due to heat and moves downward to block the lower cavity 11. The fluid flows from the inlet 13 to the middle cavity 10, flows through the through hole 8 into the upper cavity 9, and flows out from the first inlet 13. When the fluid temperature decreases, the temperature-sensing actuator 5 cools down and contracts. At the same time, the first elastic element 6 drives the first valve 4 to reset and block the upper cavity 9. The fluid flows from the inlet 13 to the middle cavity 10, flows through the lower cavity 11, and flows out from the second inlet 13.

[0032] By configuring a valve sleeve 1 and a temperature control valve 2, with the temperature control valve 2 including a temperature control valve seat 3, a first valve 4, a temperature-sensing actuator 5, a first elastic element 6, and a second valve 7, the temperature control valve seat 3 divides the valve sleeve 1 into an upper cavity 9, a middle cavity 10, and a lower cavity 11, and provides different liquid ports connected to them. This allows the temperature control valve 2 to adjust the oil circuit according to the fluid temperature, eliminating the need for frequent manual intervention. It can respond to temperature changes more accurately and efficiently, greatly improving stability and reliability, and effectively meeting the oil circuit adjustment needs of various equipment.

[0033] The temperature control valve seat 3 includes a valve frame 15, a sealing seat 16 disposed at the lower end of the valve frame 15 for sealing the valve sleeve 1, a first valve ring 17 disposed on the valve frame 15 for sealing the first valve 4, and a second valve ring 18 disposed on the valve frame 15 for sealing the second valve 7. A plurality of sealing rings 19 are arranged on the sealing seat 16.

[0034] By setting the temperature control valve seat 3, which includes a valve frame 15, a sealing seat 16, a first valve ring 17, and a second valve ring 18, the valve frame 15 provides a stable support structure for the entire temperature control valve 2, ensuring that all components are installed securely. The sealing rings 19 arranged on the sealing seat 16 significantly enhance the sealing performance of the valve sleeve 1, effectively preventing oil leakage and avoiding resource waste, environmental pollution, and equipment failure caused by leakage, thus reducing maintenance costs. The first valve ring 17 and the second valve ring 18 provide precise positioning and sealing positions for the first valve 4 and the second valve 7, respectively, and better divide the valve sleeve 1 into the upper cavity 9, the middle cavity 10, and the lower cavity 11, making the valve action more precise and reliable, thereby improving the overall control accuracy of the temperature control valve 2.

[0035] The temperature-sensing drive component 5 includes a temperature-sensing wax 20, a temperature-sensing push block 21, and a push rod 22 passing through the temperature-sensing push block 21. The temperature-sensing wax 20 is arranged between the temperature-sensing push block 21 and the push rod 22.

[0036] The temperature-sensing actuator 5 includes a temperature-sensing wax 20, a temperature-sensing push block 21, and a push rod 22. Utilizing the extremely sensitive nature of the temperature-sensing wax 20 to temperature changes, it can quickly and accurately detect fluctuations in fluid temperature. Once the temperature changes, the temperature-sensing wax 20 expands or contracts, precisely pushing the temperature-sensing push block 21 and push rod 22 to actuate, causing the valve to make corresponding adjustments and achieving precise regulation of the oil circuit. This results in a more sensitive temperature response and higher regulation accuracy, meeting the stringent requirements for precise oil temperature control.

[0037] The first valve ring 17 is provided with a limiting snap ring 23 that abuts against the first valve 4.

[0038] A limiting snap ring 23, which abuts against the first valve 4, is provided within the first valve ring 17 to precisely limit the range of motion of the first valve 4. This not only ensures that the first valve 4 operates accurately within its specified stroke, avoiding sealing defects or control errors caused by excessive movement, but also further improves the stability and repeatability of valve operation. Through this limiting design, the temperature control valve 2 maintains high precision in controlling the oil circuit during long-term use, enhancing the overall reliability and durability of the temperature control valve 2.

[0039] The second valve 7 is provided with a sealing gasket 24 at the lower end of the temperature-sensing push block 21.

[0040] A sealing gasket 24 is installed at the lower end of the temperature-sensing push block 21 along the second valve 7, further enhancing the sealing effect at the second valve 7. Even under high pressure or complex operating conditions, it can effectively prevent fluid leakage from the second valve 7, ensuring precise switching of the oil circuit and improving the accuracy of the temperature control valve 2 in controlling the oil circuit. Good sealing performance helps maintain stable system pressure, ensures normal equipment operation, and reduces a series of problems that may be caused by leakage, such as reduced efficiency and equipment damage.

[0041] The lower cavity 11 is provided with a second elastic element 25 that is in contact with and connected to the second valve 7.

[0042] A second elastic element 25, which abuts against the second valve 7, is arranged within the lower cavity 11, providing reliable assistance for the reset of the second valve 7. When the temperature changes, the second elastic element 25 can respond synchronously with the first elastic element 6, assisting the second valve 7 to return to its initial position in a timely manner or adjust to the corresponding position according to the temperature, greatly improving the response speed and reliability of the temperature control valve 2. This ensures that the temperature control valve 2 can still stably and quickly adjust the oil circuit when facing frequent temperature fluctuations, meeting the equipment's requirements for rapid oil temperature response control.

[0043] like Figures 1 to 4 As shown, this utility model achieves temperature-sensing and regulating oil circuit by setting valve sleeve 1 and temperature control valve 2, greatly improving stability and reliability and reducing manual intervention. The temperature control valve seat 3 provides support, sealing, and valve positioning, effectively preventing leakage and improving control accuracy. The temperature-sensing actuator 5 responds sensitively to temperature changes and can precisely regulate the oil circuit. The valve's limit, sealing, and reset auxiliary designs further optimize the performance of temperature control valve 2 in terms of accuracy, sealing, and response speed.

[0044] In this embodiment 2,

[0045] like Figures 3 to 4 As shown, in this invention, when the fluid temperature is higher than 50°C, the temperature-sensing wax 20 in the temperature-sensing drive 5 expands due to heat. Since the temperature-sensing wax 20 fills between the temperature-sensing push block 21 and the push rod 22, the expanded temperature-sensing wax 20 pushes the temperature-sensing push block 21 and the push rod 22 downwards. As the temperature-sensing push block 21 moves downwards, the second valve 7 connected to it also moves downwards, thereby sealing the lower cavity 11. At this time, the flow path of the fluid changes. After flowing into the middle cavity 10 from the inlet 13, the fluid flows into the upper cavity 9 through the through hole 8 of the first valve 4, and finally flows out from the first liquid outlet 12 connected to the upper cavity 9.

[0046] When the fluid temperature is below 50°C, the temperature-sensing wax 20 contracts due to the cooling. The temperature-sensing push block 21 and push rod 22 move upwards under the elastic force of the first elastic element 6, thereby blocking the through-hole 8 of the first valve 4 and thus the upper cavity 9. Simultaneously, the second elastic element 25 in the lower cavity 11 pushes the second valve 7 upwards, opening the lower cavity 11. At this time, the fluid flows into the middle cavity 10 from the inlet 13 and then directly flows out through the lower cavity 11 from the second outlet 14, which communicates with the lower cavity 11.
