Description

Technical Field

[0001] This disclosure relates to the field of valve technology, and in particular to a water temperature control valve, valve assembly, and vehicle. Background Technology

[0002] The vehicle's thermal management system plays a crucial role in regulating the temperature of the cabin and internal components. Currently, traditional proportional three-way valves are commonly used in vehicles to control the temperature of the mixed water pipes. These traditional proportional three-way valves have their outlets located between the cold water inlet and the hot water inlet. They adjust the cross-sectional areas of the cold and hot water inlets by the reciprocating motion of the valve core within the valve body, thereby controlling the flow of cold and hot water into the valve chamber and ultimately controlling the temperature of the mixed water.

[0003] While this method can control the water temperature in the mixing water pipe, it cannot completely shut off the cold water inlet and the hot water inlet. Water from the cold water pipe and / or the hot water pipe will always flow through the valve body. When the mixing water is not needed, the traditional proportional three-way valve cannot close the valve body. Summary of the Invention

[0039] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0040] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0041] The vehicle's thermal management system plays a crucial role in regulating the temperature of the cabin and internal components. Currently, vehicles generally use traditional proportional three-way valves to control the temperature of the mixed water pipes. These valves adjust the cross-sectional areas of the cold water inlet and hot water inlet by the reciprocating motion of the valve core inside the valve body, thereby controlling the flow of cold water and hot water into the valve chamber and thus controlling the temperature of the mixed water.

[0042] While this method can control the water temperature in the mixing water pipe, it cannot achieve a complete shut-off action. There will always be water flowing through the valve body from the cold water pipe and / or hot water pipe. When the mixing water is not needed, the traditional proportional three-way valve cannot close the valve body.

[0043] Based on this, this embodiment provides a water temperature control valve, valve assembly, and vehicle. By setting two first baffles, the valve body can completely shut off the hot water and cold water pipes, thereby enhancing the functionality and regulating capability of the entire water temperature control valve and significantly improving its practicality. The following detailed description uses specific embodiments as examples:

[0044] Reference Figure 1 and Figures 8 to 13 As shown, the water temperature control valve provided in this embodiment includes: a valve body 11, a valve stem 12, a valve core shell 13, and a baffle assembly; the valve body 11 includes a hot water inlet 21, a cold water inlet 22, a mixed water outlet 23, and a valve cavity, wherein the cold water inlet 22, the hot water inlet 21, and the mixed water outlet 23 are respectively connected to the valve cavity; the valve core shell 13 is disposed on the valve body 11 and closes the valve cavity; the valve stem 12 is rotatably disposed on the valve body 11, and the baffle assembly includes two first baffles 31, which are arranged circumferentially on the valve stem 12. At at least one rotation angle, the projections of the two first baffles 31 along the extension direction of the valve stem 12 coincide with the projections of the hot water inlet 21 and the cold water inlet 22 in the same direction.

[0045] The two first baffles 31 enable the valve body 11 to completely shut off the hot water pipe 24 and the cold water pipe 25, thereby making the entire water temperature control valve more functional and more adjustable, and significantly improving the practicality of the water temperature control valve.

[0046] In some embodiments, the baffle assembly further includes at least one second baffle 32, which is circumferentially disposed on the valve stem 12 and located between two first baffles 31. In a further embodiment, the number of second baffles 32 is two; the two second baffles 32 are arranged circumferentially on the valve stem 12, and when one second baffle 32 completely covers the hot water inlet 21, the projection of the other second baffle 32 in the extension direction along the valve stem 12 is tangent to the projection of the cold water inlet 22 in the same direction. By setting the second baffle 32, the water temperature control valve can more flexibly cut off the hot water inlet 21 and / or the cold water inlet 22. In a further embodiment, there are two second baffles 32. When one second baffle 32 completely covers the hot water inlet 21, the outer edge of the other second baffle 32 coincides with the outer edge of the cold water inlet 22. The line connecting one second baffle 32 and the valve stem 12 is perpendicular to the line connecting the two first baffles 31. The two second baffles 32 are set at 135 degrees. By setting the first baffles 31 and the second baffles 32 in this way, the idle stroke is reduced when the valve stem 12 is rotated, ensuring the adjustment effect of the entire water temperature control valve and enabling faster adjustment to the appropriate mixed water temperature.

[0047] In some embodiments, the valve stem 12 has a perforated part 121 at one end located inside the valve cavity. A first baffle 31 and a second baffle 32 are arranged circumferentially on the perforated part 121. The perforated part 121 has a channel for connecting the valve cavity and the mixed water outlet 23. Correspondingly, the valve core shell 13 has a through hole connecting the hot water inlet 21, the cold water inlet 22, and the mixed water outlet 23. In a further embodiment, the mixed water outlet 23 is located at the center of the valve cavity. The perforated part 121 ensures that the mixed water outlet 23 is located in the middle of the valve cavity, allowing the hot and cold water to mix thoroughly before flowing out. It also facilitates the coplanar arrangement of the first baffle 31 and the second baffle 32 on the valve stem 12 with the hot water inlet 21 and the cold water inlet 22, improving the shielding effect of the first baffle 31 and the second baffle 32 and ensuring the adjustment accuracy of the water temperature control valve.

[0048] Continue to refer to Figure 8 As shown, the valve core shell 13 is a shell structure, and the valve stem 12 passes through the valve core shell 13 and is mounted on the valve body 11. The valve core shell 13 is made of a high and low temperature resistant material and is located inside the valve body 11. The valve core shell 13 makes the structure of the entire valve cavity more reliable, reduces the influence of water temperature on the valve cavity, and further improves the accuracy of the water temperature at the mixed water outlet 23. At the same time, this split design makes the later maintenance of the water temperature control valve more convenient. If a certain part is damaged, only the structure of the damaged part needs to be replaced or repaired, resulting in lower maintenance costs.

[0049] Continue to refer to Figure 4 As shown, the surface of the valve core shell 13 that mates with the valve cavity includes a limiting mechanism 4. The valve cavity includes a part that matches the limiting mechanism 4. The valve core shell 13 is connected to the valve cavity through the limiting mechanism 4. It should be noted that there can be multiple limiting mechanisms 4. By setting the limiting mechanism 4, the valve core shell 13 can be positioned when it is placed into the valve cavity, thereby ensuring that the through holes opened on the valve core shell 13 are aligned with the hot water inlet 21, the cold water inlet 22, and the mixed water outlet 23. It can also prevent the valve core shell 13 from rotating due to the impact of water flow when the water temperature control valve is working, which would affect the water temperature regulation. It should be understood that the limiting mechanism 4 can be a guide bar and guide groove structure with a concave-convex fit. The guide bar and guide groove are both set along the sliding direction of the valve core shell 13. This setting can also improve the stability of the valve core shell 13 during the sliding process into the valve cavity.

[0050] Continue to refer to Figure 8As shown, the water temperature control valve also includes a limiting ring 7 disposed on the inner wall of the valve core housing 13. In the extension direction of the valve stem 12, at least a portion of the projection of the limiting ring 7 coincides with at least a portion of the projection of the baffle assembly. It should be understood that the limiting ring 7 and the bottom of the valve core housing 13 form a limiting groove structure, the edge of the baffle assembly rotates in the limiting groove, and the limiting ring 7 can prevent the baffle assembly from moving away from the bottom of the valve core housing 13. By setting the limiting ring 7, not only can the baffle assembly be stably moved in the limiting groove, reducing the shaking when the baffle assembly rotates, but the sealing performance at the edge of the baffle assembly can also be improved.

[0051] In some embodiments, a sealing element 5 is provided at the connection between the valve core housing 13 and the valve body 11, as well as at the connection between the valve core housing 13 and the valve stem 12. By providing the sealing element 5, the sealing performance of the entire water temperature control valve can be improved, the probability of water leakage can be reduced, and the reliability of the water temperature control valve can be improved. It should be understood that the sealing element 5 can be a rubber ring or a rubber gasket.

[0052] In a further embodiment, the valve chamber is a cylindrical cavity; this allows hot and cold water to rotate and flow more easily within the valve chamber, enhancing the fluidity of the water flow within the valve chamber and improving the speed and effect of mixing hot and cold water.

[0053] Continue to refer to Figures 4 to 6 As shown, the hot water inlet 21 is connected to the hot water pipe 24 through the first channel 211, and the cold water inlet 22 is connected to the cold water pipe 25 through the second channel 221. Both the first channel 211 and the second channel 221 are set at a set angle to the mixing water pipe 26. It should be understood that the relative arrangement of the first channel 211 and the second channel 221 can form a vortex-promoting structure through the tilt angle of the first channel 211 and the second channel 221. When hot water and cold water flow into the valve cavity from the hot water inlet 21 and the cold water inlet 22, the two water flows rotate and merge into mixed water in the valve cavity. This arrangement can make the hot water and cold water mix more fully in the valve cavity, thereby ensuring the accuracy of the water temperature at the mixed water outlet 23.

[0054] In some embodiments, the water temperature control valve further includes an actuator 14, which is disposed on the valve body 11, and a valve stem 12 is mounted on the actuator 14. The actuator 14 is used to drive the valve stem 12 to rotate.

[0055] Continue to refer to Figure 10 As shown, at this time, the two first baffles 31 block the hot water inlet 21 and the cold water inlet 22 respectively, so that the water temperature control valve is in a fully shut-off state and no warm water flows out of the mixed water outlet 23.

[0056] Continue to refer to Figure 11As shown, at this time, one of the second baffles 32 completely blocks the hot water inlet 21, while the cold water inlet 22 is completely open, so that the water temperature control valve is in a state of full cold water inflow and full cold water outflow, and the liquid temperature flowing out of the mixed water outlet 23 is the same as the liquid temperature at the cold water inlet 22.

[0057] Continue to refer to Figure 12 As shown, at this time, one of the second baffles 32 completely blocks the cold water inlet 22, while the hot water inlet 21 is completely open, so that the water temperature control valve is in the state of full hot water flowing in and full hot water flowing out, and the liquid temperature flowing out of the mixed water outlet 23 is the same as the liquid temperature at the hot water inlet 21.

[0058] Continue to refer to Figure 13 As shown, at this time, the two second baffles 32 partially block the hot water inlet 21 and the cold water inlet 22 respectively, and the area blocked by the hot water inlet 21 is larger than the area blocked by the cold water inlet 22, so that the water temperature control valve is in a state of a small amount of hot water flowing in and a large amount of cold water flowing in. The liquid temperature flowing out of the mixed water outlet 23 is lower than the liquid temperature at the hot water inlet 21 and higher than the liquid temperature at the cold water inlet 22. At the same time, the temperature difference between the liquid flowing out of the mixed water outlet 23 and the liquid at the cold water inlet 22 is smaller.

[0059] Continue to refer to Figures 9 to 13 As shown, both the hot water inlet 21 and the cold water inlet 22 are elliptical openings, and the mixed water outlet 23 is a circular opening, which facilitates the flow and mixing of water in the valve cavity. The first baffle 31 and the second baffle 32 are also elliptical baffles with the same or slightly larger dimensions as the hot water inlet 21 and the cold water inlet 22, thereby ensuring the shielding effect of the baffles. At the same time, the first baffle 31 and the second baffle 32 are connected to the hollow part 121 through a plate-like structure. The end of the plate-like structure passes through the center of the first baffle 31 or the second baffle 32 and extends to the other side of the first baffle 31 or the second baffle 32.

[0060] Continue to refer to Figures 1 to 3 As shown, the water temperature control valve has an overall columnar structure, which is simple and compact, making it easier to wrap an insulation layer on the outside, thus effectively reducing the heat loss of the water temperature control valve.

[0061] Secondly, this disclosure provides a valve assembly, which continues to refer to Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 14As shown, the valve assembly includes multiple water temperature control valves as described above. The two ends of the hot water pipe 24 are respectively provided with a male head structure 61 and a female seat structure 62 that match the shape. The two ends of the cold water pipe 25 are respectively provided with a male head structure 61 and a female seat structure 62 that match the shape. The male head structure 61 of any one of the multiple water temperature control valves is sequentially connected to the female seat structure 62 of another water temperature control valve.

[0062] This configuration makes it easier to combine and install multiple water temperature control valves, allowing them to be combined arbitrarily according to actual needs, thus improving the flexibility of the thermal management system. Moreover, multiple water temperature control valves can share the same hot water pipe 24 and cold water pipe 25, which can effectively reduce costs.

[0063] Thirdly, this disclosure provides a vehicle including the water temperature control valve as described above, and / or the valve assembly as described above.
