Description

Technical Field

[0001] The present disclosure relates to the technical field of solenoid valves, and in particular, to a solenoid valve, a thermal management system and a vehicle. Background Art

[0002] The solenoid valve includes an integrated valve body and a valve seat installed on the integrated valve body, and the valve seat is used to be installed on components such as a valve core. The integrated valve body is provided with a mounting hole for the valve seat to extend into, the inner side of the mounting hole is connected to the flow channel of the solenoid valve, and is provided with an internal thread, and the valve seat is provided with an external thread that matches the internal thread.

[0003] The integrated valve body is usually made of aluminum, and the valve seat is usually made of magnetic steel. The hardness of steel is much greater than that of aluminum. In the process of screwing the internal and external threads, the external threads of the valve seat can easily cut off the aluminum of the internal threads of the integrated valve body, forming aluminum chips. The aluminum chips will fall into the flow channel of the integrated valve body along the gap between the mounting hole and the valve seat, and then enter the flow channel of the entire thermal management system, causing the solenoid valve to get stuck and the injection molding machine to wear, seriously affecting the service life of the thermal management system.

DETAILED DESCRIPTION

[0028] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0029] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", may be based on the structure of the relevant parts themselves, or may be based on the orientation of the relevant parts when used in combination, for example: the "inside" of the annular boss is used to connect the flow channel, and the "outer peripheral surface" of the annular boss is formed with an external thread, where the "inside" refers to the side of the annular boss close to the center of the ring, and the "outer peripheral surface" refers to the outer wall surface of the annular boss away from the center of the ring; the pressure ring is constructed as a cap-like structure that surrounds the annular boss and extends "inwardly" to press against the expanded diameter part, where the "inward" extension refers to the extension in the direction toward the center of the annular boss; the "inner edge" and "outer edge" of the upper surface of the annular boss are formed with a first chamfer, where the "inner edge" refers to the edge of the annular boss close to the center of the ring, and the "outer edge" refers to the edge of the annular boss away from the center of the ring.

[0030] In the present disclosure, the terms "first", "second", etc. are used to distinguish one element from another element, and do not have order and importance. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0031] Reference Figure 1-Figure 4The present disclosure exemplarily shows a solenoid valve, including an integrated valve body 100 and a valve seat 200 installed on the integrated valve body 100. The end face 101 of the integrated valve body 100 is provided with an annular boss 110, the inner side of the annular boss 110 is used to connect the flow channel 120, the outer peripheral surface of the annular boss 110 is formed with an external thread 310, and the valve seat 200 partially surrounds the annular boss 110 and has an internal thread 320 matched with the external thread 310.

[0032] In order to facilitate the understanding of the technical solution, the basic structure of the solenoid valve is introduced here. In addition to the above-mentioned integrated valve body 100 and valve seat 200, the solenoid valve also includes a valve body including a valve core assembly, etc., which will be described below. The valve body can be fixed to the valve seat 200 and indirectly fixed to the integrated valve body 100 through the valve seat 200. Among them, when the valve seat 200 is fixed to the integrated valve body 100, the valve body can extend into the interior of the integrated valve body 100 through the inner side of the annular boss 110 and form a matching relationship with the flow channel 120. In addition, it should be noted that the above-mentioned "the inner side of the annular boss 110 is used to connect the flow channel 120" does not mean that the liquid in the flow channel can flow to the inner side of the annular boss 110, but means that the valve body can extend into the interior of the integrated valve body 100 through this position and form a match with the flow channel 120. Since the structure and principle of the solenoid valve are well known to those skilled in the art, they are not described here.

[0033] The present disclosure does not limit the specific structure of the integrated valve body 100. As long as one end face 101 forms an annular boss 110, and the inner side of the annular boss 110 is connected to the flow channel 120 inside the integrated valve body 100, the end face 101 can be used as the mounting surface of the valve seat 200, and the outer contour of the integrated valve body 100 can be a cube, a rectangular parallelepiped, etc.

[0034] The present disclosure does not limit the specific structure of the valve seat 200, as long as it partially surrounds the outer side of the annular boss 110 and an internal thread 320 is formed at this position to cooperate with the external thread 310. The specific structure will be introduced below and will not be repeated here.

[0035] By using the above technical solution, an external thread 310 is provided on the outer periphery of the annular boss 110, and an internal thread 320 matching the external thread 310 is provided on the portion of the valve seat 200 surrounding the annular boss 110. When the valve seat 200 is screwed and fixed to the integrated valve body 100, metal fragments generated by the internal thread 320 and the external thread 310 during the screwing process can be retained on the outer side of the annular boss 110, so as to prevent the metal fragments from entering the flow channel 120 through the gap between the inner side of the annular boss 110 and the valve seat 200 and causing damage to the solenoid valve or the thermal management system.

[0036] Reference Figure 3In the embodiment of the present disclosure, the valve seat 200 may have an annular groove 201 for the annular boss 110 to extend into, and the internal thread 320 is provided on the inner side of the annular groove 201. The annular groove 201 can improve the connection stability between the valve seat 200 and the annular boss 110, and limit the movement of the valve seat 200 relative to the integrated valve body 100 to deflect the central axis, so as to ensure that the two can remain relatively still.

[0037] Reference Figure 3 In an embodiment of the present disclosure, the valve seat 200 may include: a valve seat body 210, which is used to extend into the inner side of the annular boss 110, and the valve seat body 210 may have a radially protruding expanded diameter portion 211; and a pressure ring 220, which is provided with an internal thread 320, and the pressure ring 220 can be used to press the expanded diameter portion 211 to the step surface 102 of the integrated valve body 100, and the pressure ring 220 and the expanded diameter portion 211 enclose an annular groove 201. With such a design, when the valve seat 200 needs to be fixed to the integrated valve body 100, the valve seat body 210 is first extended into the inner side of the annular boss 110, and then the pressure ring is screwed onto the outer side of the annular boss 110 through the cooperation of the internal thread 320 and the external thread 310. At this time, the pressure ring 220 and the expanded diameter portion 211 enclose an annular groove 201, and the pressure ring 220 can press the expanded diameter portion 211 to the step surface 102 of the integrated valve body 100. Specifically, the pressure ring 220 can be pressed against the upper end surface of the expanded diameter portion 211 to limit the valve seat body 210 from axially disengaging from the annular boss 110.

[0038] It needs to be explained that in Figure 3 In the illustrated embodiment, the aforementioned “step surface 102” may refer to the portion of the end surface 101 of the integrated valve body 100 located inside the annular boss 110. In addition, in some other embodiments, the “step surface 102” may also refer to other surfaces formed on the integrated valve body 100 and staggered with the end surface 101. For example, in some embodiments, in the axial direction of the valve seat 200, the step surface 102 may be closer to the flow channel 120 than the end surface 101.

[0039] The present disclosure does not limit the relationship between the valve seat body 210 and the pressure ring 220. For example, in the above-mentioned embodiment, the two can be independent of each other and combined during installation, and the valve seat body 210 can be compressed and fixed by the pressure ring 220. In addition, in some other embodiments, the pressure ring 220 and the valve seat body 210 can also be integrally formed. In this case, as long as the pressure ring 220 is fixedly connected to the annular boss 110 during installation, the valve seat body 210 is also indirectly fixedly connected to the annular boss 110 (integrated valve body 100).

[0040] In order to prevent the valve seat body 210 from moving radially inside the annular boss 110, in the embodiment of the present disclosure, the outer diameter of the enlarged diameter portion 211 may be the same as the inner diameter of the annular boss 110. In addition, in some other embodiments, the outer diameter of the enlarged diameter portion 211 may be smaller than the inner diameter of the annular boss 110. In this case, a sealing ring or other material may be sleeved on the outer periphery of the enlarged diameter portion 211 to fill the gap between the enlarged diameter portion 211 and the annular boss 110. In addition, such a design can also form a sealing protection for the internal space of the integrated valve body 100, effectively preventing impurities and the like from entering the internal flow channel 120.

[0041] The present disclosure does not limit the specific structure of the pressure ring 220. Figure 1-Figure 4 In the illustrated embodiment, the pressing ring 220 may be configured as a cap-like structure surrounding the annular boss 110 and extending radially inward to press against the enlarged diameter portion 211 .

[0042] In order to ensure that the pressure ring 220 can press the enlarged diameter portion 211 to the end surface (the second step surface 420) of the integrated valve body 100, refer to Figure 3 In the embodiment of the present disclosure, the axial length of the enlarged diameter portion 211 may be greater than the height of the annular boss 110. With such a design, when the bottom surface of the enlarged diameter portion 211 abuts against the end surface (the second step surface 420) of the integrated valve body 100, the top surface of the enlarged diameter portion 211 is higher than the top surface of the annular boss 110, so that the pressure ring 220 can press the enlarged diameter portion 211. In addition, in some other embodiments, the axial length of the enlarged diameter portion 211 may also be less than the height of the annular boss 110. In this case, the pressure ring 220 needs to at least partially protrude toward the end surface of the integrated valve body 100 and be used to abut against the top surface of the enlarged diameter portion 211.

[0043] In the embodiment of the present disclosure, in order to avoid the internal thread 320 and the external thread 310 being cut by the harder one to form metal chips when they are matched, the material of the pressure ring 220 and the annular boss 110 can be the same, that is, the material of the internal thread 320 and the external thread 310 is the same, thereby reducing the cutting chips generated when the two are matched.

[0044] The present disclosure does not limit the materials of the pressure ring 220 and the annular boss 110. For example, in some embodiments, the pressure ring 220 and the annular boss 110 may be made of aluminum, that is, the internal thread 320 and the external thread 310 are respectively made of aluminum. Aluminum has the advantages of being light and easy to machine.

[0045] The working principle of the solenoid valve is to control the opening and closing of the valve by applying electromagnetic force, and the magnitude of the electromagnetic force is related to the magnetic conductivity of the valve seat 200. Therefore, the magnetic conductivity of the valve seat 200 can make the sensitivity of the solenoid valve higher and increase the magnitude of the electromagnetic force, thereby improving the control accuracy of the valve. At the same time, the magnetically conductive valve seat 200 can improve the sealing performance of the solenoid valve, reduce the occurrence of leakage, and ensure the reliable operation of the equipment. Therefore, in the embodiment of the present disclosure, the material of the valve seat body 210 can be steel.

[0046] As described above, the solenoid valve may further include a valve body 230 having a valve core assembly. The valve body 230 may be fixedly connected to the valve seat 200 , and specifically, the valve body 230 and the valve seat body 210 may be welded.

[0047] In order to facilitate the insertion of the annular boss 110 into the annular groove 201 to avoid collision and interference, refer to Figure 3 In the embodiment of the present disclosure, the end surface of the annular boss 110 may have a first inner edge 410 and a first outer edge 420, and the end surface of the annular groove 201 may have a second inner edge 430 corresponding to the position of the first inner edge 410, and a third inner edge 440 corresponding to the position of the first outer edge 420. Among them, at least one of the first inner edge 410 and the second inner edge 430 may be formed with a first chamfer 510, or at least one of the first outer edge 420 and the third inner edge 440 may be formed with a second chamfer 520. In addition, in some other embodiments, at least one of the first inner edge 410 and the second inner edge 430 may be formed with a first chamfer 510, and at least one of the first outer edge 420 and the third inner edge 440 may be formed with a second chamfer 520. By designing the first chamfer 510 and the second chamfer 520, when the annular boss 110 is extended into the annular groove 201, it can be more convenient to align and operate more conveniently.

[0048] According to a second aspect of the present disclosure, a thermal management system is provided, including a fluid channel and the above-mentioned solenoid valve, wherein the flow channel 120 can be connected to the fluid channel. Since the thermal management system has all the beneficial effects of the above-mentioned solenoid valve, they are not described in detail here.

[0049] According to a third aspect of the present disclosure, a vehicle is provided, comprising the above-mentioned thermal management system. Since the vehicle has all the beneficial effects of the above-mentioned thermal management system, they are not described in detail here.

[0050] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0051] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0052] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
