Description

Technical Field

[0001] This invention relates to the field of temperature control valves, and more particularly to an electronic temperature control valve with a heating plug adjustment structure. Background Technology

[0002] Precise temperature control is crucial in various systems involving fluid transport and temperature control, such as automotive engine cooling systems, industrial heat exchange systems, and HVAC systems. However, existing thermostatic valve technologies on the market have many shortcomings. Traditional thermostatic valves mainly rely on mechanical structures and simple temperature sensing elements, and their temperature control accuracy is insufficient to meet the demands of modern high-precision systems. Most traditional thermostatic valves can only passively respond to changes in ambient temperature, lacking active adjustment capabilities. In practical applications, systems often need to flexibly adjust fluid temperature based on various factors, such as equipment operating status and ambient temperature trends. However, traditional thermostatic valves cannot meet these flexible and variable control requirements, limiting the overall performance and adaptability of the system. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an electronic temperature control valve with a heating plug adjustment structure, in view of the current state of the prior art.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: an electronic temperature control valve with a heating plug adjustment structure, including a valve sleeve and a temperature control valve disposed in the valve sleeve. The temperature control valve includes a heating plug for heating, a temperature sensing drive component disposed at the lower end of the heating plug, and a switching valve disposed at the lower end of the temperature sensing drive component. The valve sleeve is divided into an upper cavity and a lower cavity along the switching valve. A first elastic element is arranged on the upper cavity along the temperature sensing drive component. A second elastic element is arranged in the lower cavity and is in contact with the switching valve. The valve sleeve has an outlet communicating with the upper cavity and an inlet communicating with the lower cavity. When the heating plug heats up, the temperature-sensing actuator expands due to heat and moves downward to block the lower cavity, stopping the fluid flow in the lower cavity. When the heating plug stops heating, the temperature-sensing actuator cools down and contracts, and simultaneously resets through the first and second elastic elements, allowing the fluid to flow from the inlet to the lower cavity and out through the upper cavity from the outlet.

[0005] The aforementioned components achieve the following effects: By incorporating a valve sleeve and a temperature control valve, the temperature control valve includes a heating plug, a temperature-sensing actuator, and a switching valve. The valve sleeve is divided into an upper chamber and a lower chamber by the switching valve. The valve sleeve has an outlet communicating with the upper chamber and an inlet communicating with the lower chamber. The temperature control valve heats and regulates the oil circuit by the temperature-sensing actuator via the heating plug. Simultaneously, the temperature control valve can also regulate the oil circuit by adjusting the temperature-sensing actuator based on fluid temperature. This allows for more precise and efficient response to temperature changes, significantly improving stability and reliability, and effectively meeting the oil circuit regulation needs of various equipment. Furthermore, through both active adjustment by the heating plug and fluid temperature regulation, it can comprehensively and precisely control the oil circuit, meeting the complex requirements for fluid temperature control under different operating conditions. This effectively solves the problems of traditional temperature control valves' single control method and insufficient precision, greatly improving the adaptability and reliability of temperature control valves in various systems.

[0006] Preferably, the heating plug includes a plug and a heating base disposed at the lower end of the plug, one end of the temperature sensing drive extends into the heating base, and a plurality of annular sealing grooves are arranged on the outer edge of the heating base, each annular sealing groove containing a sealing ring.

[0007] The aforementioned components achieve the following effects: the heating plug includes a plug and a heating base, with a sealing ring on the outer edge of the heating base, achieving both precise heating and excellent sealing. The tight fit between the heating base and the temperature-sensing actuator ensures efficient heat transfer to the temperature-sensing wax, thereby quickly adjusting the state of the temperature-sensing actuator. The sealing ring effectively prevents fluid leakage.

[0008] Preferably, the temperature-sensing drive component includes a temperature-sensing wax, a temperature-sensing hollow rod with an inner cavity, a temperature-sensing head sleeved on the upper end of the temperature-sensing hollow rod, and a push rod passing through the inner cavity and the temperature-sensing head, wherein the temperature-sensing wax is arranged in the inner cavity.

[0009] The aforementioned components achieve the following effect: The temperature-sensing actuator includes a temperature-sensing wax, a temperature-sensing rod, a temperature-sensing head, and a push rod. Utilizing the high sensitivity of the temperature-sensing wax to temperature changes, it can quickly and accurately convert temperature changes into the mechanical action of the push rod, thereby precisely controlling the switching valve. This improves the temperature sensing accuracy and response speed of the thermostatic valve, enabling rapid and precise responses to both heating from the heating plug and changes in fluid temperature. Both the temperature-sensing rod and the temperature-sensing head are made of stainless steel.

[0010] Preferably, the push rod extends along the upper end of the temperature sensing head and is provided with a fixing seal. One end of the push rod is arranged in the heating seat along the fixing seal. The fixing seal includes a heating fixing head, a sealing ring and a limiting retaining ring arranged sequentially from top to bottom.

[0011] The aforementioned components achieve the following effects: the push rod is securely mounted within the heating base via a fixed sealing element, including a heating fixing head, a sealing ring, and a limiting retaining ring assembly. This ensures excellent sealing between the push rod and the heating base, preventing fluid leakage, and also guarantees the stability of the push rod during movement. This aids heat transfer and optimizes the performance of the temperature-sensing actuator. Furthermore, it enhances the reliability and control accuracy of the temperature control valve, ensuring its stable operation during long-term use.

[0012] Preferably, a limiting snap ring is provided at the upper end of the heating plug along the inner edge of the valve sleeve.

[0013] The aforementioned components achieve the following effect: a limiting spring is provided inside the valve sleeve along the upper end of the heating plug, which precisely limits the position of the heating plug. This ensures that the position of the heating plug inside the valve sleeve remains stable, preventing excessive movement due to external forces or vibrations, and ensuring that the relative position of the heating plug and the temperature-sensing drive component remains precise and unchanged. This maintains the stability and reliability of the temperature control valve and extends its service life.

[0014] Preferably, the switching valve is provided with a sealing gasket at the lower end of the temperature-sensing push block.

[0015] The aforementioned components achieve the following effect: A sealing gasket is installed at the lower end of the temperature-sensing push block of the switching valve, further enhancing the sealing performance at the switching valve. During fluid flow, especially under pressure fluctuations, the sealing gasket effectively prevents fluid leakage from the switching valve, ensuring that the fluid flows strictly according to the designed path and improving the accuracy of the temperature control valve in controlling the fluid flow path.

[0016] Preferably, the temperature sensing rod has a Y-shaped design.

[0017] The effect achieved by the above components is that the Y-shaped design of the temperature sensing rod makes it easier for the temperature sensing head to be better fitted onto the top of the temperature sensing rod.

[0018] Compared with the prior art, the advantages of this invention are: by setting a valve sleeve and a temperature control valve, and the temperature control valve including a heating plug, a temperature sensing actuator, and a switching valve, the oil circuit is regulated by actively heating the temperature sensing actuator through the heating plug, and at the same time, the temperature sensing actuator can be adjusted according to the temperature of the fluid itself, thereby precisely controlling the oil circuit.

[0026] In this embodiment 1, like Figures 1 to 5 As shown, the present invention provides an electronic temperature control valve with a heating plug adjustment structure, including a valve sleeve 1 and a temperature control valve 2 disposed within the valve sleeve 1. The temperature control valve 2 includes a heating plug 3 for heating, a temperature sensing drive 4 disposed at the lower end of the heating plug 3, and a switching valve 5 disposed at the lower end of the temperature sensing drive 4. The valve sleeve 1 is divided into an upper cavity 6 and a lower cavity 7 along the switching valve 5. A first elastic element 8 is arranged on the upper cavity 6 along the temperature sensing drive 4. A second elastic element 9 is arranged in the lower cavity 7 and is in contact with and connected to the switching valve 5. The valve sleeve 1 has an outlet 10 communicating with the upper cavity 6 and an inlet 11 communicating with the lower cavity 7. When the heating plug 3 heats up, the temperature-sensing drive 4 expands due to heat and moves downward to seal the lower cavity 7, stopping the flow of fluid in the lower cavity 7. When the heating plug 3 stops heating, the temperature-sensing drive 4 cools down and contracts, and simultaneously resets through the first elastic element 8 and the second elastic element 9. The fluid flows from the inlet 11 to the lower cavity 7, through the upper cavity 6, and out from the outlet 10. Through the coordinated action of the first elastic element 8 and the second elastic element 9, the reset time is shortened by 1-2 seconds, effectively improving the efficiency of synchronous reset.

[0027] By setting up a valve sleeve 1 and a temperature control valve 2, the temperature control valve 2 includes a heating plug 3, a temperature sensing actuator 4, and a switching valve 5. The valve sleeve 1 is divided into an upper chamber 6 and a lower chamber 7 by the switching valve 5. The valve sleeve 1 has an outlet 10 communicating with the upper chamber 6 and an inlet 11 communicating with the lower chamber 7. The temperature control valve 2 heats and regulates the oil circuit by heating the temperature sensing actuator 4 through the heating plug 3. At the same time, the temperature control valve 2 can also regulate the oil circuit by regulating the temperature sensing actuator 4 through the fluid temperature. This allows for more precise and efficient response to temperature changes, greatly improving stability and reliability, and effectively meeting the oil circuit regulation needs of various equipment.

[0028] Furthermore, through both active adjustment by the heating plug 3 and fluid temperature regulation, the oil circuit can be controlled comprehensively and precisely to meet the complex requirements for fluid temperature control under different operating conditions. This effectively solves the problems of the traditional temperature control valve 2's single control method and insufficient precision, greatly improving the adaptability and reliability of the temperature control valve 2 in various systems.

[0029] The heating plug 3 includes a plug 12 and a heating base 13 disposed at the lower end of the plug 12. One end of the temperature sensing drive 4 extends into the heating base 13. Several annular sealing grooves are arranged on the outer edge of the heating base 13. Each annular sealing groove contains a sealing ring 14. In this embodiment, the sealing ring 14 is preferably a fluororubber sealing ring 14.

[0030] The heating plug 3 includes a plug 12 and a heating base 13, with a sealing ring 14 on the outer edge of the heating base 13, achieving both precise heating and good sealing. The tight fit between the heating base 13 and the temperature-sensing actuator 4, with the heating base 13 having a thermal conductivity ≥200W / m·K, ensures efficient heat transfer to the temperature-sensing wax 15, thereby quickly adjusting the state of the temperature-sensing actuator 4. The sealing ring 14 effectively prevents fluid leakage, specifically reducing the leakage rate to 0.1-0.3mL / min.

[0031] The temperature-sensing drive component 4 includes a temperature-sensing wax 15, a temperature-sensing hollow rod 16 with an inner cavity, a temperature-sensing head 17 sleeved on the upper end of the temperature-sensing hollow rod 16, and a push rod 18 passing through the inner cavity and the temperature-sensing head 17. The temperature-sensing wax 15 is arranged in the inner cavity.

[0032] The temperature-sensing actuator 4 includes a temperature-sensing wax 15, a temperature-sensing rod 16, a temperature-sensing head 17, and a push rod 18. Utilizing the high sensitivity of the temperature-sensing wax 15 to temperature changes, it can quickly and accurately convert temperature changes into the mechanical action of the push rod 18, thereby precisely controlling the switching valve 5. This improves the temperature sensing accuracy (measurement range: -200℃~+850℃, accuracy is ((0.30+0.005*|t|) degrees Celsius, where |t| refers to the absolute value of the actual temperature of the measured medium)) and response speed (improved by 30%-50%) of the temperature control valve 2. Whether it is heating by the heating plug 3 or changes in fluid temperature, it can quickly and accurately respond (shortening the response time by 20%-30%). The temperature-sensing rod 16 and the temperature-sensing head 17 are preferably made of stainless iron.

[0033] The push rod 18 extends along the upper end of the temperature sensing head 17 and is provided with a fixing seal 19. One end of the push rod 18 is arranged in the heating base 13 along the fixing seal 19. The fixing seal 19 includes a heating fixing head 20, a sealing ring 21 and a limiting retaining ring 22 arranged sequentially from top to bottom.

[0034] One end of the push rod 18 is securely mounted within the heating base 13 via an extended fixing seal 19. This ensures excellent sealing between the push rod 18 and the heating base 13, preventing fluid leakage, and also ensures the stability of the push rod 18 during movement. This aids in heat transfer and optimizes the performance of the temperature-sensing actuator 4. It further enhances the reliability and control accuracy of the temperature control valve 2, ensuring its stable operation during long-term use.

[0035] The valve sleeve 1 is provided with a limiting snap ring 23 at the upper end of the heating plug 3 along the inner edge.

[0036] A limiting snap ring 23 is provided inside the valve sleeve 1 along the upper end of the heating plug 3, which plays a precise limiting role in the heating plug 3. This ensures that the position of the heating plug 3 inside the valve sleeve 1 remains stable, avoiding excessive movement due to external force or vibration, and ensuring that the relative position of the heating plug 3 and the temperature sensing drive 4 remains precise and unchanged, thereby maintaining the stability and reliability of the temperature control valve 2 and extending its service life.

[0037] The switching valve 5 is provided with a sealing gasket 24 at the lower end of the temperature-sensing push block.

[0038] A sealing gasket 24 is installed at the lower end of the temperature-sensing push block of the switching valve 5, which further enhances the sealing performance of the switching valve 5. During fluid flow, especially under pressure fluctuations, the sealing gasket 24 can effectively prevent fluid leakage from the switching valve 5, ensuring that the fluid flows strictly according to the design path and improving the accuracy of the temperature control valve 2 in controlling the fluid passage.

[0039] The temperature sensing rod 16 has a Y-shaped design.

[0040] The Y-shaped design of the temperature sensing rod 16 facilitates the better mounting of the temperature sensing head 17 on the top of the temperature sensing rod 16. Through fluid simulation analysis, the Y-shaped temperature sensing rod 16 provides a stable mounting for the temperature sensing head 17, reducing flow field disturbance and resistance by 10%-15%.

[0041] like Figures 1 to 5 As shown, this invention uses a valve sleeve 1 and a temperature control valve 2, where the temperature control valve 2 includes a heating plug 3, a temperature-sensing actuator 4, and a switching valve 5. The heating plug 3 actively heats the temperature-sensing actuator 4 to regulate the oil circuit, and at the same time, it can adjust the temperature-sensing actuator 4 according to the temperature of the fluid itself, thereby precisely controlling the oil circuit.

[0042] In this embodiment 2, like Figures 1 to 5 As shown, the working principle of this invention is as follows: When adjusted via the heating plug 3, the heating plug 3 is energized through the plug piece 12 to begin heating. Heat is transferred through the heating base 13 to the temperature-sensing drive 4, and then through the push rod 18 to the temperature-sensing wax 15 inside the temperature-sensing hollow rod 16. The temperature-sensing wax 15 is extremely sensitive to temperature changes and expands rapidly upon heating. The expansion force of the temperature-sensing wax 15 pushes the temperature-sensing head 17 and the push rod 18 downwards, thereby causing the switching valve 5 to move downwards. After the switching valve 5 moves downwards, it blocks the lower cavity 7, preventing fluid from passing through the lower cavity 7 and thus changing the fluid's flow path. When heating stops, as the temperature decreases, the temperature-sensing wax 15 contracts, and the temperature-sensing head 17 and the push rod 18 return to their original position upwards under the elastic force of the first elastic element 8 and the second elastic element 9. The switching valve 5 moves upwards, opening the lower cavity 7, and the fluid flows from the inlet 11 into the lower cavity 7, and then flows out through the outlet 10 through the upper cavity 6.

[0043] When fluid temperature is regulated, changes in the fluid's own temperature directly affect the temperature-sensing actuator 4. When the fluid temperature rises, the temperature-sensing wax 15 in the temperature-sensing actuator 4 expands, pushing the push rod 18 and the switching valve 5 downwards, blocking the lower cavity 7, and changing the fluid passage to adjust the temperature. When the fluid temperature decreases, the temperature-sensing wax 15 contracts, and the temperature-sensing head 17 and the push rod 18 return to their original position upwards under the elastic force of the first elastic element 8 and the second elastic element 9. The switching valve 5 moves upwards, opening the lower cavity 7, and the fluid flows from the inlet 11 into the lower cavity 7, and then flows out from the outlet 10 through the upper cavity 6, thus realizing automatic adjustment of the fluid passage according to the fluid temperature and keeping the system temperature stable.

[0044] In this embodiment 3, like Figure 5 As shown, the heating plug's power decreases as the temperature rises. The power gradually decreases with increasing temperature. When the temperature starts to rise from room temperature, the heating plug's power is 100% (90℃), which is the maximum power. As the temperature continues to rise, the power gradually decreases. When the temperature reaches 95℃, the power drops to 80%. When the temperature continues to rise to 100℃, the power drops to 60%. When the temperature reaches 105℃, the power drops to 40%. Finally, when the temperature reaches 110℃, the power drops to 20%. When the temperature reaches 115℃, the power drops to 0%.

[0045] Rated power supply temperature rise curve (①): Curve ① represents the "rated power supply temperature rise curve". This invention adjusts the relationship between the temperature rise of the oil circuit and the power through the heating socket.

[0046] Electricity-free temperature rise curve (②): Curve ② represents the "electricity-free temperature rise curve". This invention regulates the temperature rise of the oil circuit by adjusting the fluid temperature.

[0047] Power supply management curve (③): Curve ③ represents the "power supply management curve", which shows the power supply management of the heating socket at different temperatures.

[0048] Traditional thermostatic valves typically only have curve ②, the non-electrical temperature rise curve, because it does not involve electronic power supply management and relies solely on fluid temperature to achieve natural temperature rise. Electronic thermostatic valves, on the other hand, introduce curves ① and ③ through additional power supply management via the heating socket, enabling more precise temperature control.

[0049] Through these two adjustment methods, the present invention can accurately and flexibly control the fluid temperature to meet the needs under different working conditions.
