Description

Technical Field

[0001] The present application relates to the field of temperature control valves, and in particular to a temperature control valve. Background Art

[0002] In the related art, when the hydraulic system of the engineering machinery is working, the temperature of the fluid will gradually increase. When the temperature of the fluid is higher than the preset temperature, the viscosity of the fluid decreases, resulting in a decrease in the lubrication effect of the fluid. The hydraulic system is provided with a cooler for cooling the fluid. When the temperature of the fluid is higher than the preset temperature, the traditional hydraulic system controls the flow of the fluid into the cooler through a temperature sensor and a reversing valve so that the cooler cools the fluid. However, this control method of controlling the flow direction of the fluid through a temperature sensor and a reversing valve needs to be controlled by an electronic control program, which increases the working complexity of the hydraulic system and increases the design difficulty of the hydraulic system. Summary of the Invention

[0003] In order to simplify the control method of fluid flow, reduce the working complexity of the hydraulic system, and reduce the design difficulty of the hydraulic system, the present application provides a temperature control valve.

[0004] The present application provides a temperature control valve that adopts the following technical solution:

[0005] A temperature-control valve comprises: a valve body and a valve core assembly, the valve body defining a delivery space and a temperature-sensing space, the delivery space forming a liquid inlet, a first liquid outlet, and a second liquid outlet on the outer peripheral wall of the valve body, the temperature-sensing space being connected to the liquid inlet, and the valve core assembly being movably mounted in the delivery space.

[0006] The temperature sensing component includes a reversing member and a temperature sensing member. The reversing member is movably arranged in the temperature sensing space. The temperature sensing member is arranged in the temperature sensing space. The reversing member is transmission-connected between the temperature sensing member and the valve core assembly. The temperature sensing member and the fluid in the temperature sensing space jointly drive the reversing member to move.

[0007] When the temperature of the fluid is lower than a preset temperature, the fluid in the temperature sensing space drives the reversing member to drive the valve core assembly to connect the liquid inlet and the first liquid outlet, and block the liquid inlet and the second liquid outlet.

[0008] When the temperature of the fluid is not lower than a preset temperature, the temperature sensing element drives the reversing element to drive the valve core assembly to connect the liquid inlet and the second liquid outlet, and block the liquid inlet and the first liquid outlet.

[0009] By adopting the above technical solution, a temperature-sensing element is provided in the temperature-sensing space. When the fluid temperature is below a preset temperature, the temperature-sensing element does not operate. The fluid in the temperature-sensing space drives the reversing element, which drives the valve core assembly to connect the liquid inlet and the first liquid outlet, while blocking the liquid inlet and the second liquid outlet. When the fluid temperature is not below the preset temperature, the temperature-sensing element operates and drives the reversing element, which drives the valve core assembly to connect the liquid inlet and the second liquid outlet, while blocking the liquid inlet and the first liquid outlet. Compared with the prior art, the fluid flow direction control method is simplified by eliminating the need for a temperature sensor and an electronic control program. This reduces the operational complexity of the hydraulic system, and thus the design difficulty of the hydraulic system.

[0011] By adopting the above technical solution, when the fluid temperature is lower than the preset temperature, the thermosensitive element does not expand, and the fluid in the temperature-sensing space drives the reversing element to move closer to the thermosensitive element, which in turn drives the valve core assembly to connect the liquid inlet and the first liquid outlet, while blocking the liquid inlet and the second liquid outlet. Furthermore, when the fluid temperature is not lower than the preset temperature, the thermosensitive element expands, entering the drive gap, and the thermosensitive element drives the push rod to extend from the housing and abut against the reversing element. The push rod drives the reversing element to move away from the thermosensitive element, which in turn drives the valve core assembly to connect the liquid inlet and the second liquid outlet, while blocking the liquid inlet and the first liquid outlet.

The third blocking portion is located between the third liquid channel and the fourth liquid channel, and the fluid in the temperature sensing space flows into the flow guide space through the third liquid channel and / or the fourth liquid channel.

When the fluid temperature is not below the preset temperature, the temperature-sensing element operates and drives the reversing element, which drives the valve core assembly to connect the liquid inlet and the second liquid outlet, while blocking the liquid inlet and the first liquid outlet. Compared with existing technologies, this eliminates the need for temperature sensors and electronic control programs to control fluid flow direction, thereby simplifying fluid flow control, reducing the operational complexity of the hydraulic system, and ultimately, simplifying the design of the hydraulic system.

[0032] 2. When the fluid temperature is lower than the preset temperature, the fluid in the temperature-sensing space drives the reversing member to move closer to the temperature-sensing member, which in turn drives the transmission member to move downward, which in turn drives the valve core to rotate around the central axis of the valve core, thereby connecting the valve core to the liquid inlet and the first liquid outlet, and blocking the liquid inlet and the second liquid outlet.

[0033] 3. The second elastic member applies an elastic force toward the liquid inlet to the back-pressure member, and the second elastic member drives the back-pressure member to move close to the liquid inlet and seal the liquid inlet. When the fluid flows into the conveying space through the liquid inlet, the fluid contacts the back-pressure member and applies a driving force away from the liquid inlet to the back-pressure member. When the driving force applied by the fluid on the back-pressure member is greater than the elastic force applied by the second elastic member on the back-pressure member, the fluid drives the back-pressure member to move away from the liquid inlet, so that the back-pressure member opens the liquid inlet, thereby realizing the use of the back-pressure component to make the fluid have a constant output pressure value, and avoiding the situation where the fluid pressure is too low and the fluid cannot drive engineering machinery equipment.

[0048] The following is combined with Figures 1-8 This application is described in further detail.

[0049] The embodiment of the present application discloses a temperature control valve 100 .

[0050] Reference Figures 1-4 The temperature control valve 100 according to the embodiment of the present application includes: a valve body 1, a valve core assembly 2 and a temperature sensing assembly 3. The valve body 1 defines a delivery space 11 and a temperature sensing space 12. The delivery space 11 forms a liquid inlet 13, a first liquid outlet 14 and a second liquid outlet 15 on the outer peripheral wall of the valve body 1. The valve core assembly 2 is movably installed in the delivery space 11. Specifically, along the first direction of the valve body 1, the delivery space 11 forms a liquid inlet 13 on the right side wall of the valve body 1. Along the height direction of the valve body 1, the delivery space 11 forms a first liquid outlet 14 on the upper end wall of the valve body 1. Along the second direction of the valve body 1, the delivery space 11 forms a second liquid outlet 15 on the front end wall of the valve body 1. The first direction of the valve body 1 can refer to Figure 4 The left and right directions in the figure, the height direction of the valve body 1 can refer to Figure 1 The second direction of the valve body 1 can refer to the up and down direction Figure 1 The front-to-back direction.

[0051] The fluid flows into the delivery space 11 through the liquid inlet 13, and the fluid in the delivery space 11 flows out of the valve body 1 through the first liquid outlet 14 or the second liquid outlet 15, and the first liquid outlet 14 is connected to the fluid inlet channel of the engineering machinery equipment, and the second liquid outlet 15 is connected to the cooler. The cooler is used to cool the fluid. After the cooler completes cooling the fluid, the fluid enters the fluid inlet channel of the engineering machinery equipment.

[0052] In some specific embodiments, the cooler may be an air-cooled cooler, but the present application is not limited thereto. The cooler may also be a water-cooled cooler, etc.

[0053] In addition, the temperature sensing space 12 is connected to the liquid inlet 13. When the fluid flows into the delivery space 11 through the liquid inlet 13, the fluid also flows into the temperature sensing space 12 through the liquid inlet 13. It should be noted that the diameter of the flow channel between the temperature sensing space 12 and the liquid inlet 13 is smaller than the diameter of the flow channel between the liquid inlet 13 and the delivery space 11. That is to say, only a small part of the fluid flows into the temperature sensing space 12 through the liquid inlet 13.

[0054] The temperature sensing component 3 includes a reversing member 31 and a temperature sensing member 32. The reversing member 31 is movably arranged in the temperature sensing space 12. The temperature sensing member 32 is arranged in the temperature sensing space 12. The reversing member 31 is transmission-connected between the temperature sensing member 32 and the valve core assembly 2. The temperature sensing member 32 and the fluid in the temperature sensing space 12 jointly drive the reversing member 31 to move. Specifically, after the fluid flows into the temperature sensing space 12 through the liquid inlet 13, the fluid accumulates in the temperature sensing space 12 and then the fluid drives the reversing member 31 to move. When the fluid temperature is not lower than the preset temperature, the temperature sensing member 32 is actuated, and the temperature sensing member 32 drives the reversing member 31 to move. In some specific embodiments, the reversing member 31 moves along the height direction of the valve body 1.

[0055] In some specific embodiments, the preset temperature may be 40°, but the present application is not limited thereto, and the preset temperature may also be 50°, etc.

[0056] In some specific embodiments, the fluid may be hydraulic oil or the like.

[0057] When the fluid temperature is lower than the preset temperature, the temperature sensing element 32 does not operate, and the fluid in the temperature sensing space 12 drives the reversing element 31 to drive the valve core assembly 2 to connect the liquid inlet 13 and the first liquid outlet 14, and blocks the liquid inlet 13 and the second liquid outlet 15. The fluid flows into the conveying space 11 through the liquid inlet 13, and the fluid in the conveying space 11 flows into the engineering machinery equipment through the first liquid outlet 14.

[0058] When the fluid temperature is not lower than the preset temperature, the temperature sensing element 32 is actuated, and the temperature sensing element 32 drives the reversing element 31 to drive the valve core assembly 2 to connect the liquid inlet 13 and the second liquid outlet 15, and block the liquid inlet 13 and the first liquid outlet 14. The fluid flows into the delivery space 11 through the liquid inlet 13, and the fluid in the delivery space 11 flows into the cooler through the second liquid outlet 15, so that the cooler cools the fluid.

[0059] In some specific embodiments, the outer peripheral wall of the reversing member 31 may be provided with a plurality of drive tooth grooves, and the plurality of drive tooth grooves are spaced apart along the height direction of the valve body 1. The valve core assembly 2 includes a valve core 21, and the valve core 21 is pivotally installed in the conveying space 11. The valve core 21 is used to connect or block the liquid inlet 13 and the first liquid outlet 14, or to connect or block the liquid inlet 13 and the second liquid outlet 15. The outer peripheral wall of the valve core 21 is provided with a drive gear, and the drive tooth groove and the drive gear are meshed and connected.

[0060] When the reversing member 31 is driven, the reversing member 31 drives the valve core 21 to rotate around the central axis of the valve core 21, so that the valve core 21 connects the liquid inlet 13 and the first liquid outlet 14, and blocks the liquid inlet 13 and the second liquid outlet 15, or connects the liquid inlet 13 and the second liquid outlet 15, and blocks the liquid inlet 13 and the first liquid outlet 14.

[0061] Furthermore, the temperature sensing element 32 divides the temperature sensing space 12 into a detection space 122 and a reversing space 123, and the detection space 122 is located above the reversing space 123. The temperature sensing element 32 is arranged in the detection space 122, and the reversing element 31 is movably arranged in the reversing space 123. The conveying space 11 is connected to the detection space 122. The fluid in the conveying space 11 flows into the detection space 122 and contacts the temperature sensing element 32. Such a setting can enable the temperature sensing element 32 to sense the fluid temperature faster, so that the temperature sensing element 32 can operate faster. The temperature control valve 100 can quickly guide the fluid above the preset temperature into the cooler, thereby improving the user experience of the temperature control valve 100.

[0062] Thus, by providing a temperature sensing element 32 in the temperature sensing space 12, when the fluid temperature is below a preset temperature, the temperature sensing element 32 does not operate. The fluid in the temperature sensing space 12 drives the reversing element 31 to drive the valve core assembly 2 to connect the liquid inlet 13 and the first liquid outlet 14, while blocking the liquid inlet 13 and the second liquid outlet 15. When the fluid temperature is not below the preset temperature, the temperature sensing element 32 operates and drives the reversing element 31 to drive the valve core assembly 2 to connect the liquid inlet 13 and the second liquid outlet 15, while blocking the liquid inlet 13 and the first liquid outlet 14. Compared with the prior art, there is no need to control the flow direction of the fluid through a temperature sensor and an electronic control program, thereby simplifying the control method of the fluid flow direction, reducing the operating complexity of the hydraulic system, and thus reducing the design difficulty of the hydraulic system.

[0063] Reference Figure 2 and Figure 5 In some embodiments of the present application, the temperature sensing element 32 includes a shell 321 and a push rod 322. The shell 321 defines a accommodating space 3211 and a driving gap 3212. The accommodating space 3211 is connected to the driving gap 3212. A thermally sensitive element 3213 suitable for thermal expansion and contraction is provided in the accommodating space 3211. The fluid is suitable for heat exchange with the shell 321. Specifically, when the fluid contacts the shell 321, the fluid exchanges heat with the thermally sensitive element 3213 in the shell 321 through the shell 321. That is, the fluid transfers heat to the thermally sensitive element 3213 through the shell 321. When the fluid temperature is lower than the preset temperature, the thermally sensitive element 3213 does not expand. When the fluid temperature is not lower than the preset temperature, the thermally sensitive element 3213 expands.

[0064] In addition, the push rod 322 is slidably set in the driving gap 3212 and opposite to the reversing member 31. When the thermistor 3213 is not expanded, the fluid in the temperature sensing space 12 drives the reversing member 31 to move closer to the temperature sensing member 32. When the thermistor 3213 expands, the thermistor 3213 drives the push rod 322 to drive the reversing member 31 to move away from the temperature sensing member 32.

[0065] Specifically, when the fluid temperature is lower than the preset temperature, the thermal sensitive element 3213 does not expand, and the fluid in the temperature sensing space 12 drives the reversing element 31 to move close to the temperature sensing element 32. The reversing element 31 drives the valve core assembly 2 to connect the liquid inlet 13 and the first liquid outlet 14, and blocks the liquid inlet 13 and the second liquid outlet 15.

[0066] When the fluid temperature is not lower than the preset temperature, the thermistor 3213 expands and enters the driving gap 3212. The thermistor 3213 drives the push rod 322 to extend out of the shell 321 and stop with the reversing member 31. The push rod 322 drives the reversing member 31 to move away from the temperature sensing member 32. The reversing member 31 drives the valve core assembly 2 to connect the liquid inlet 13 and the second liquid outlet 15, and blocks the liquid inlet 13 and the first liquid outlet 14, thereby achieving the technical effect of driving the reversing member 31 to move by the thermistor 3213 and the fluid in the temperature sensing space 12.

[0067] It should be noted that when the thermal element 3213 is in an expanded state and the temperature of the fluid is lower than a preset temperature, the thermal element 3213 contracts, and the fluid-driven reversing element 31 drives the push rod 322 to extend into the housing 321 .

[0068] In some specific embodiments, the heat-sensitive element 3213 is preferably temperature-sensitive wax.

[0069] Further, refer to Figure 2 and Figure 3 The temperature sensing space 12 is provided with an avoidance hole 124, and the avoidance hole 124 is located on the side of the reversing member 31 away from the temperature sensing member 32. The avoidance hole 124 is connected to the liquid inlet 13. That is to say, along the height direction of the valve body 1, the temperature sensing member 32 is located above the reversing member 31, and the avoidance hole 124 is located below the reversing member 31. The fluid flows into the temperature sensing space 12 through the avoidance hole 124, and the fluid in the temperature sensing space 12 contacts the lower end of the reversing member 31 and drives the reversing member 31 to move close to the temperature sensing member 32.

[0070] Reference Figure 2 and Figure 6In some embodiments of the present application, the temperature sensing component 3 may further include a first elastic member 33. The temperature sensing member 32 is movably arranged in the temperature sensing space 12. The first elastic member 33 can be elastically deformed and arranged between the temperature sensing member 32 and the end wall of the temperature sensing space 12. The first elastic member 33 is sleeved on the outer peripheral wall of the temperature sensing member 32. Specifically, along the height direction of the valve body 1, one end of the first elastic member 33 is stopped against the upper end wall of the temperature sensing space 12, and the other end of the first elastic member 33 is stopped against the temperature sensing member 32.

[0071] After the heat-sensitive element 3213 expands, the heat-sensitive element 3213 drives the push rod 322 to drive the reversing element 31 to move away from the temperature-sensing element 32. When the reversing element 31 stops at the lower end wall of the temperature-sensing space 12, the heat-sensitive element 3213 continues to expand and drives the push rod 322 to extend out of the shell 321, and the push rod 322 stops at the reversing element 31. The push rod 322 applies a force on the shell 321 in the direction away from the reversing element 31 through the heat-sensitive element 3213. The push rod 322 drives the shell 321 to move away from the reversing element 31 through the heat-sensitive element 3213. The shell 321 compresses the first elastic element 33. Compared with the shell 321 being fixedly set in the temperature-sensing space 12, such a configuration can prevent the heat-sensitive element 3213 from breaking the shell 321 when the reversing element 31 stops at the lower end wall of the temperature-sensing space 12 and the heat-sensitive element 3213 continues to expand, thereby improving the working reliability of the temperature control valve 100.

[0072] When the thermosensitive element 3213 is in an expanded state and the fluid temperature is lower than a preset temperature, the thermosensitive element 3213 contracts, the fluid drives the reversing element 31 to drive the push rod 322 into the housing 321 , and the first elastic element 33 drives the housing 321 to move closer to the reversing element 31 .

[0073] In some specific embodiments, the first elastic member 33 is preferably a spring.

[0074] Reference Figure 2 、 Figure 4 and Figure 6 In some embodiments of the present application, the valve core assembly 2 includes a valve core 21 and a transmission member 22, and the delivery space 11 is divided into a guide space 111 and a driving space 112. Along the first direction of the shell 321, the guide space 111 is located on the right side of the driving space 112, and the guide space 111 forms a liquid inlet 13, a first liquid outlet 14 and a second liquid outlet 15 on the outer peripheral wall of the valve body 1.

[0075] In addition, the valve core 21 is pivotally arranged in the guide space 111, and the transmission member 22 is slidingly arranged in the driving space 112. The transmission member 22 is transmission-connected between the valve core 21 and the reversing member 31. The reversing member 31 drives the transmission member 22 to drive the valve core 21 to rotate around the central axis of the valve core 21. The valve core 21 is used to connect or block the liquid inlet 13 and the first liquid outlet 14, or to connect or block the liquid inlet 13 and the second liquid outlet 15.

[0076] In some specific embodiments, the transmission member 22 moves along the height direction of the valve body 1. When the fluid temperature is lower than the preset temperature, the fluid in the temperature sensing space 12 drives the reversing member 31 to move close to the temperature sensing member 32, and the reversing member 31 drives the transmission member 22 to move downward. The transmission member 22 drives the valve core 21 to rotate around the central axis of the valve core 21, so that the valve core 21 connects the liquid inlet 13 and the first liquid outlet 14, and blocks the liquid inlet 13 and the second liquid outlet 15.

[0077] When the fluid temperature is not lower than the preset temperature, the temperature sensing member 32 drives the reversing member 31 to move away from the temperature sensing member 32, the reversing member 31 drives the transmission member 22 to move upward, and the transmission member 22 drives the valve core 21 to rotate around the central axis of the valve core 21, so that the valve core 21 connects the liquid inlet 13 and the second liquid outlet 15, and blocks the liquid inlet 13 and the first liquid outlet 14, thereby achieving the technical effect of controlling the valve core 21 to guide the fluid to the first liquid outlet 14 or the second liquid outlet 15 through the reversing member 31.

[0078] Reference Figure 2 、 Figure 4 and Figure 6 In some embodiments of the present application, along the height direction of the valve body 1, a first chamber 1121 is defined between the top wall of the transmission member 22 and the top wall of the driving space 112, and a second chamber 1122 is defined between the bottom wall of the transmission member 22 and the bottom wall of the driving space 112. That is to say, a first cavity is defined between the upper end wall of the transmission member 22 and the upper end wall of the driving space 112, and a second cavity is defined between the lower end wall of the transmission member 22 and the lower end wall of the driving space 112.

The first liquid channel 16 is connected between the temperature sensing space 12 and the first chamber 1121, and the second liquid channel 17 is connected between the temperature sensing space 12 and the second chamber 1122. The liquid in the temperature sensing space 12 flows into the first chamber 1121 through the first liquid channel 16, or flows into the second chamber 1122 through the second liquid channel 17.

[0080] The fluid-driven transmission member 22 in the driving space 112 drives the valve core 21 to rotate. When the fluid temperature is lower than the preset temperature, the reversing member 31 connects the first liquid channel 16 and the temperature sensing space 12, and blocks the second liquid channel 17 and the temperature sensing space 12. When the fluid temperature is not lower than the preset temperature, the reversing member 31 connects the second liquid channel 17 and the temperature sensing space 12, and blocks the first liquid channel 16 and the temperature sensing space 12.

The fluid in the first chamber 1121 drives the transmission member 22 to move close to the lower end wall of the driving space 112, and the transmission member 22 drives the valve core 21 to rotate, so that the valve core 21 connects the liquid inlet 13 and the first liquid outlet 14, and blocks the liquid inlet 13 and the second liquid outlet 15.

[0082] When the fluid temperature is not lower than the preset temperature, the fluid in the temperature sensing space 12 flows into the second chamber 1122 through the second liquid channel 17, and the fluid in the temperature sensing space 12 cannot flow into the first chamber 1121 through the first liquid channel 16. The fluid in the second chamber 1122 drives the transmission member 22 to move close to the upper end wall of the driving space 112, and the transmission member 22 drives the valve core 21 to rotate, so that the valve core 21 connects the liquid inlet 13 and the second liquid outlet 15, and blocks the liquid inlet 13 and the first liquid outlet 14, thereby achieving the technical effect of the reversing member 31 driving the transmission member 22 to drive the valve core 21 to rotate.

[0083] Furthermore, when the transmission member 22 moves close to the lower end wall of the driving space 112, the transmission member 22 squeezes the fluid in the second chamber 1122, and the fluid in the second chamber 1122 flows into the temperature sensing space 12 through the second liquid channel 17. When the transmission member 22 moves close to the upper end wall of the driving space 112, the transmission member 22 squeezes the fluid in the first chamber 1121, and the fluid in the first chamber 1121 flows into the temperature sensing space 12 through the first liquid channel 16.

A seal is provided between the outer peripheral wall of the reversing member 31 and the inner peripheral wall of the temperature sensing space 12. After the fluid flows into the temperature sensing space 12 through the avoidance hole 124, it can only flow into the first communicating hole 311.

[0087] Specifically, when the fluid temperature is lower than the preset temperature, the fluid in the temperature sensing space 12 drives the reversing member 31 to move close to the temperature sensing member 32, the outer peripheral wall of the second blocking portion 314 and the inner peripheral wall of the third blocking portion 121 are press-fitted and sealed, the first connecting hole 311 is connected to the first liquid channel 16 and blocked from the second liquid channel 17, and the fluid in the temperature sensing space 12 flows into the first liquid channel 16 through the first connecting hole 311 and the first liquid outlet hole 312 in turn, and the fluid in the first liquid channel 16 flows into the first chamber 1121.

[0088] When the fluid is not lower than the preset temperature, the temperature sensing component 32 drives the reversing component 31 to move away from the temperature sensing component 32, the outer peripheral wall of the first blocking portion 313 is press-fitted with the inner peripheral wall of the third blocking portion 121 and is sealed, the first connecting hole 311 is connected to the second liquid channel 17 and is blocked from the first liquid channel 16, and the fluid in the temperature sensing space 12 flows into the second liquid channel 17 through the first connecting hole 311 and the first liquid outlet hole 312 in turn, and the fluid in the second liquid channel 17 flows into the second chamber 1122, thereby achieving the technical effect of controlling the fluid in the temperature sensing space 12 to flow into the first chamber 1121 or the second chamber 1122 through the reversing component 31.

[0089] Reference Figure 2 、 Figure 6 and Figure 7In some embodiments of the present application, the valve body 1 defines a third liquid channel 18 and a fourth liquid channel 19, and the third liquid channel 18 and the fourth liquid channel 19 are both connected between the temperature sensing space 12 and the flow guide space 111, and the third blocking portion 121 is located between the third liquid channel 18 and the fourth liquid channel 19. Specifically, along the height direction of the valve body 1, the third liquid channel 18 is located above the third blocking portion 121, and the fourth liquid channel 19 is located below the third blocking portion 121. The third liquid channel 18 is suitable for communicating with the first liquid channel 16, and the fourth liquid channel 19 is suitable for communicating with the second liquid channel 17.

[0090] In addition, the fluid in the temperature sensing space 12 flows into the guide space 111 through the third liquid channel 18 and / or the fourth liquid channel 19. Specifically, when the second blocking portion 314 is pressed against the third blocking portion 121, the fluid in the first chamber 1121 drives the transmission member 22 to move close to the lower end wall of the driving space 112, and the transmission member 22 squeezes the fluid in the second chamber 1122. The fluid in the second chamber 1122 flows into the guide space 111 through the second liquid channel 17 and the fourth liquid channel 19 in turn.

[0091] When the first blocking part 313 is pressed against the third blocking part 121, the fluid in the second chamber 1122 drives the transmission part 22 to move close to the upper end wall of the driving space 112, and the transmission part 22 squeezes the fluid in the first chamber 1121. The fluid in the first chamber 1121 flows into the guide space 111 through the first liquid channel 16 and the third liquid channel 18 in turn, thereby achieving the technical effect of recycling the fluid in the first chamber 1121 and the fluid in the second chamber 1122.

[0092] Reference Figure 2 and Figure 8 In some embodiments of the present application, a plurality of driving grooves 221 are provided on the outer peripheral wall of the transmission member 22, and the plurality of driving grooves 221 are spaced apart along the height direction of the valve body 1. A plurality of driving teeth 211 are provided at the end of the valve core 21 away from the liquid inlet 13, and the plurality of driving teeth 211 are spaced apart along the circumferential direction of the valve core 21, and the driving grooves 221 and the driving teeth 211 are meshed and connected.

[0093] It should be noted that the guide space 111 and the driving space 112 are connected, the end of the valve core 21 away from the liquid inlet 13 extends into the driving space 112, and the outer peripheral wall of the valve core 21 and the inner peripheral wall of the guide space 111 are sealed and connected, and the driving tooth 211 is arranged at the end of the valve core 21 extending into the driving space 112.

[0094] Specifically, when the transmission member 22 is driven by the fluid in the first chamber 1121 or the fluid in the second chamber 1122, the transmission member 22 drives the valve core 21 to rotate around the central axis of the valve core 21 through the driving groove 221 and the driving teeth 211, thereby achieving the technical effect of driving the valve core 21 to rotate through the transmission member 22.

[0095] Reference Figure 4 and Figure 8 In some embodiments of the present application, a second communicating hole 212 is provided at the end of the valve core 21. Specifically, along the first direction of the valve body 1, the second communicating hole 212 is located on the right side wall of the valve core 21, and a second liquid outlet hole 213 is provided on the outer peripheral wall of the valve core 21. The second communicating hole 212 and the second liquid outlet hole 213 are connected. The second communicating hole 212 is opposite to and connected with the liquid inlet 13. When the valve core 21 is driven by the transmission member 22, the second liquid outlet hole 213 is driven to be opposite to and connected with the first liquid outlet 14 or the second liquid outlet 15. After the fluid enters the guide space 111 through the liquid inlet 13, the fluid in the guide space 111 flows into the first liquid outlet 14 or the second liquid outlet 15 through the second communicating hole 212 and the second liquid outlet hole 213 in sequence.

[0096] Specifically, when the transmission member 22 moves close to the lower end wall of the driving space 112, the transmission member 22 drives the valve core 21 to rotate, and the valve core 21 drives the second liquid outlet 213 to be opposite to and connected with the first liquid outlet 14, and the fluid flows into the first liquid outlet 14 through the liquid inlet 13, the second connecting hole 212 and the second liquid outlet 213 in sequence.

[0097] When the transmission member 22 moves close to the upper end wall of the driving space 112, the transmission member 22 drives the valve core 21 to rotate, and the valve core 21 drives the second liquid outlet 213 to be opposite to and connected with the second liquid outlet 15. The fluid flows into the second liquid outlet 15 through the liquid inlet 13, the second connecting hole 212 and the second liquid outlet hole 213 in turn, thereby achieving the technical effect of controlling the flow direction of the fluid in the guide space 111 by the valve core 21.

[0098] Reference Figure 4 In some embodiments of the present application, the temperature control valve 100 may further include: a back pressure component 4, the back pressure component 4 includes a back pressure part 41 and a second elastic part 42, the back pressure part 41 is movably arranged in the conveying space 11, along the first direction of the valve body 1, one end of the back pressure part 41 is opposite to the liquid inlet 13 and is used to open or block the liquid inlet 13, the second elastic part 42 is elastically deformably arranged between the other end of the back pressure part 41 and the end wall of the conveying space 11, specifically, the right side wall of the back pressure part 41 is opposite to the liquid inlet 13, and the second elastic part 42 is elastically deformably arranged between the left side wall of the back pressure part 41 and the left side wall of the conveying space 11.

[0099] When the fluid does not flow into the conveying space 11 through the liquid inlet 13, the second elastic member 42 applies an elastic force toward the liquid inlet 13 to the back pressure member 41, and the second elastic member 42 drives the back pressure member 41 to move close to the liquid inlet 13 and block the liquid inlet 13. When the fluid flows into the conveying space 11 through the liquid inlet 13, the fluid contacts the back pressure member 41 and applies a driving force away from the liquid inlet 13 to the back pressure member 41. When the driving force applied by the fluid on the back pressure member 41 is greater than the elastic force applied by the second elastic member 42 on the back pressure member 41, the fluid drives the back pressure member 41 to move away from the liquid inlet 13, so that the back pressure member 41 opens the liquid inlet 13, and the fluid flows into the conveying space 11 and then flows out of the conveying space 11 through the first liquid outlet 14 or the second liquid outlet 15. In this way, the back pressure component 4 can be used to make the fluid have a constant output pressure value, which can avoid the fluid pressure being too low and causing the fluid to be unable to drive engineering machinery and equipment.

[0100] Furthermore, designers can make the fluid have different constant pressure values by replacing different second elastic members 42 . Different second elastic members 42 exert different elastic forces on the back pressure member 41 toward the liquid inlet 13 .

[0101] In some specific embodiments, the second elastic member 42 is preferably a spring.

[0102] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
