[0041] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0042] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0043] The valve structure 100 according to an embodiment of the first aspect of the present invention will be described below with reference to the accompanying drawings.

[0044] like Figure 1-Figure 10 As shown, the valve structure 100 according to the embodiment of the first aspect of the present invention comprises: a valve body 1, a valve cover 2, a valve core bracket 3, a valve core 4 and a driving mechanism 5, the valve body 1 is formed with a valve cavity 11, and the valve cover 2 is detachably covered at the opening of the valve cavity 11. That is to say, the valve cover 2 is detachably connected to the valve body 1, and the valve cover 2 can better cover the valve cavity 11 after being connected to the valve body 1, so that the cooperation between the valve body 1 and the valve cover 2 can play a good protective effect on the components in the valve cavity 11. In addition, during the later maintenance of the valve structure 100, the valve cavity 11 can be exposed after the valve cover 2 is removed from the valve body 1, which is convenient for checking the internal structure of the valve cavity 11 and helps to reduce the maintenance difficulty of the valve structure 100. In a specific example, the valve cover 2 is connected to the valve body 1 by threaded fasteners, which can reduce the use cost while ensuring the close cooperation between the valve cover 2 and the valve body 1.

[0045] Among them, the valve core bracket 3 is arranged on the valve cover 2 and is located in the valve cavity 11, and the valve core 4 is rotatably arranged on the valve core bracket 3 and is located in the valve cavity 11. That is to say, the valve core 4 is connected to the valve cover 2 through the valve core bracket 3, so that the valve core 4 can be assembled into an integrated structure with the valve cover 2 and the valve core bracket 3 before being installed in the valve cavity 11. Therefore, during the assembly process of the valve structure 100, the combination of the valve cover 2, the valve core bracket 3 and the valve core 4 can be directly inserted into the valve cavity 11, and it is only necessary to connect the valve cover 2 and the valve body 1, that is, the combination of the valve cover 2, the valve core bracket 3 and the valve core 4 is plug-in matched with the valve body 1, which is conducive to simplifying the assembly steps of the valve structure 100, and in the process of later maintenance of the valve structure 100, after the valve cover 2 is removed from the valve body 1, the valve core 4 can be withdrawn from the valve cavity 11 together, which is convenient for the inspection and replacement of the valve core 4, etc., which is conducive to reducing the maintenance difficulty of the valve structure 100. In addition, the assembly of the valve cover 2, the valve core bracket 3 and the valve core 4 can be carried out outside the valve cavity 11, thereby ensuring that the valve cover 2, the valve core bracket 3 and the valve core 4 have sufficient assembly space to reduce the difficulty of assembling the valve cover 2, the valve core bracket 3 and the valve core 4, which is beneficial to reducing the assembly difficulty of the valve structure 100 and improving the assembly efficiency of the valve structure 100.

[0046] Furthermore, the driving mechanism 5 is used to drive the valve core 4 to rotate. Thus, the flow path in the valve structure 100 can be opened and closed and the flow rate can be controlled by driving the valve core 4 to rotate by the driving mechanism 5, thereby realizing the opening and closing, switching or flow rate regulation of the flow path connected to the valve structure 100.

[0047] According to the valve structure 100 of the embodiment of the present invention, the valve core bracket 3 is arranged on the valve cover 2 and is located in the valve cavity 11, and the valve core 4 is rotatably arranged on the valve core bracket 3 and is located in the valve cavity 11, so that during the assembly process of the valve structure 100, the combination of the valve cover 2, the valve core bracket 3 and the valve core 4 can be directly inserted into the valve cavity 11, which is conducive to simplifying the assembly steps of the valve structure 100. At the same time, the assembly of the valve cover 2, the valve core bracket 3 and the valve core 4 can be carried out outside the valve cavity 11, which can ensure that the valve cover 2, the valve core bracket 3 and the valve core 4 have sufficient assembly space, which is conducive to reducing the assembly difficulty of the valve structure 100 to improve the assembly efficiency of the valve structure 100, and in the later maintenance process of the valve structure 100, after the valve cover 2 is removed from the valve body 1, the valve core 4 can be withdrawn from the valve cavity 11 together, which is convenient for the inspection, replacement and other operations of the valve core 4, which is conducive to reducing the maintenance difficulty of the valve structure 100.

[0048] According to some embodiments of the present invention, the valve core bracket 3 is detachably connected to the valve cover 2. That is, the valve core bracket 3 and the valve cover 2 are independently formed, and the valve core bracket 3 can be installed on the valve cover 2 to connect the valve core 4 and the valve cover 2. The valve core bracket 3 can also be removed from the valve cover 2 to release the connection between the valve core 4 and the valve cover 2, which is convenient for replacing or maintaining the valve core 4 and the valve core bracket 3. Therefore, the design and production difficulty of the valve core bracket 3 and the valve cover 2, which are independently formed, are low, and the production and processing of the valve core bracket 3 and the valve cover 2 can be carried out at the same time, which is conducive to improving production efficiency. At the same time, it is conducive to reducing the maintenance cost of the valve structure 100. For example, when the valve core bracket 3 is damaged, only the housing of the valve core bracket 3 needs to be replaced to save maintenance costs. Among them, the valve core bracket 3 and the valve cover 2 can be connected by threaded fasteners. The threaded fasteners have the advantages of simple structure and easy assembly. The valve core bracket 3 and the valve cover 2 can be tightly connected by threaded fasteners. In addition, while ensuring the connection strength between the valve core bracket 3 and the valve cover 2, the cost can also be reduced. Optionally, the threaded fastener may be a screw, a bolt or a stud. In a specific example, the valve cover 2 is formed with an assembly hole 22, the valve core bracket 3 is formed with a matching hole 313 corresponding to the assembly hole 22, and the threaded fastener is passed through the assembly hole 22 and the matching hole 313 to fix the valve core bracket 3 on the valve cover 2.

[0049] It should be noted that this is only an explanation of one of the connection methods between the valve core bracket 3 and the valve cover 2, and is not a limitation on the connection method between the valve core bracket 3 and the valve cover 2. For example, the valve core bracket 3 and the valve cover 2 can also be connected by welding, riveting, etc. to enhance the firm connection between the valve core bracket 3 and the valve cover 2.

[0050] According to some embodiments of the present invention, the valve core 4 is spherical, that is, the valve structure 100 is a ball valve, thereby making the valve structure 100 easy to operate, quick and convenient to open and close, and having a simple structure and convenient for later maintenance.

[0051] In some examples, the valve core support 3 is detachably connected to the valve cover 2, and the valve core 4 is spherical. Therefore, the valve structure 100 has a simple structure, and the production difficulty and maintenance cost of the valve cover 2 and the valve core support 3 can be reduced.

[0052] According to some embodiments of the present invention, a limiting space 30 is formed in the valve core bracket 3, and the valve core 4 is rotatably accommodated in the limiting space 30. In other words, the valve core 4 is completely located in the limiting space 30 and is rotatable relative to the valve core bracket 3, so that while ensuring that the valve core 4 can be connected to the valve cover 2 through the valve core bracket 3, it is ensured that the valve core 4 can control the on-off, reversing or flow adjustment of the fluid in the pipeline through rotation, and in addition, the protective effect of the valve core bracket 3 on the valve core 4 can be better improved.

[0053] According to some embodiments of the present invention, the valve core bracket 3 includes a bracket body 31 and an elastic valve seat 32, the valve body 1 has a valve port 12 connected to the valve cavity 11, the valve core 4 has a switching channel 41, and an installation hole 311 connecting the valve port 12 and the limiting space 30 is formed on the bracket body 31. The elastic valve seat 32 is arranged in the installation hole 311 and is located between the bracket body 31 and the valve core 4. A through hole 321 connected to the valve port 12 and suitable for connecting to the switching channel 41 is formed on the elastic valve seat 32. That is, when the valve core 4 rotates so that the switching channel 41 is connected to the through hole 321, the switching channel 41 can be connected to the valve port 12 through the through hole 321, and the elastic valve seat 32 is arranged between the valve core 4 and the bracket body 31. It can be understood that the elastic valve seat 32 is relatively soft, so that the elastic valve seat 32 can be more closely fitted with the bracket body 31 and the valve core 4 through the deformation of the elastic valve seat 32, that is, the gap between the bracket body 31 and the valve core 4 can be filled by the elastic valve seat 32, and at the same time, the contact friction between the valve core 4 and the bracket body 31 and the valve body 1 can be better avoided by the elastic valve seat 32. Therefore, the fluid can be better prevented from leaking through the gap between the valve core 4 and the bracket body 31 through the elastic valve seat 32, which is beneficial to improving the sealing performance of the valve structure 100, and at the same time, it can avoid friction damage to the valve core 4, which is beneficial to extending the service life of the valve structure 100. In addition, the support body 31 and the elastic valve seat 32 are formed independently, so that the materials of the support body 31 and the elastic valve seat 32 can be flexibly selected according to the needs. For example, the support body 31 can be made of a material with high structural strength, such as the support body 31 can be a metal part, and the elastic valve seat 32 can be supported by a relatively soft material, such as the elastic valve seat 32 can be a rubber part, etc.

[0054] Specifically, at least two valve ports 12 are provided, and the valve structure 100 can be connected to the external pipeline through the valve ports 12, that is, the side of the valve port 12 away from the through hole 321 is suitable for connecting to the external pipeline, and the valve core 4 is driven to rotate by the driving mechanism 5 to adjust the relative position of the valve core 4 and the valve core bracket 3, so as to realize the connection or cutoff of the switching channel 41 and the through hole 321, and then realize the on-off, reversing or flow regulation between the multiple external pipelines connected to the valve port 12. Therefore, when the switching channel 41 is connected to the through hole 321, the multiple external pipelines connected to the valve port 12 can form a connected flow path through the switching channel 41, and the fluid in the external pipeline on the upstream side can flow into the external pipeline on the downstream side through the switching channel 41. When the switching channel 41 is connected to the through hole 321, the elastic valve seat 32 can better fill the gap between the valve core 4 and the bracket body 31 to prevent the fluid from leaking from the gap between the valve core 4 and the bracket body 31 and causing loss.

[0055] According to some embodiments of the present invention, a receiving groove 322 surrounding the through hole 321 is formed on the side of the elastic valve seat 32 facing the valve core 4, and a portion of the valve core 4 is located in the receiving groove 322. Thus, by accommodating a portion of the valve core 4 in the receiving groove 322, the elastic valve seat 32 can better limit the freedom of movement of the valve core 4, thereby preventing the valve core 4 from being offset relative to the valve core bracket 3, which is beneficial to improving the stability of the connection between the valve core 4 and the valve core bracket 3.

[0056] Furthermore, the valve core 4 is spherical, and in the direction from the valve core 4 to the valve port 12, the inner wall surface of the receiving groove 322 extends obliquely toward the center of the elastic valve seat 32. In other words, the inner wall of the receiving groove 322 is formed as an arc surface, so that the inner wall of the receiving groove 322 can adapt to the outer peripheral contour of the spherical valve core 4, thereby better improving the contact area between the elastic valve seat 32 and the valve core 4, which is conducive to further improving the sealing effect of the elastic valve seat 32 between the valve core 4 and the bracket body 31. In a specific example, a plurality of valve ports 12 are formed on the valve body 1, and the plurality of valve ports 12 are arranged at intervals along the circumference of the valve core 4. An elastic valve seat 32 is provided between each valve port 12 and the valve core 4. The plurality of elastic valve seats 32 are arranged along the circumference of the valve core 4. In the direction toward the through hole 321, the end surface of one side of the elastic valve seat 32 toward the valve core 4 extends obliquely toward the direction away from the valve core, and smoothly transitions with the inner circumferential wall of the through hole 321 to form a bowl-shaped receiving groove 322 on the side of the elastic valve seat 32 toward the valve core 4.

[0057] According to some embodiments of the present invention, a sealing lip 323 is formed on the side of the elastic valve seat 32 facing away from the valve core 4, and the sealing lip 323 abuts against the inner wall of the valve cavity 11 and is in a ring shape surrounding the outer peripheral side of the valve port 12. That is, in the extension direction of the through hole 321, the side of the elastic valve seat 32 facing the valve core 4 abuts against the valve core 4, and the other side of the elastic valve seat 32, i.e., the side facing away from the valve core 4 abuts against the inner wall of the valve cavity 11 located at the outer periphery of the valve port 12 through the sealing lip 323, so that an uninterrupted flow path can be formed between the valve port 12 and the through hole 321, that is, the fluid can be better prevented from leaking through the gap between the elastic valve seat 32 and the inner wall of the valve cavity 11 when flowing between the through hole 321 and the valve port 12. As a result, the sealing performance of the lift valve structure 100 is improved, and at the same time, the loss caused by fluid leakage can be avoided.

[0058] According to some embodiments of the present invention, the inner diameter of the mounting hole 311 is reduced in the direction from the valve core 4 to the valve port 12. That is, in the extension direction of the mounting hole 311, the inner diameter of the end of the mounting hole 311 adjacent to the valve core 4 is larger than the inner diameter of the end of the mounting hole 311 away from the valve core 4. In the extension direction of the mounting hole 311, the outer diameter of the elastic valve seat 32 remains substantially unchanged. After the valve core 4 is installed in the valve core bracket 3, the elastic valve seat 32 bears the outward thrust of the valve core 4. Therefore, by reducing the inner diameter of the end of the mounting hole 311 away from the valve core 4, the mounting hole 311 can better block the elastic valve seat 32 to prevent the valve seat from escaping from the end of the mounting hole 311 away from the valve core 4. At the same time, during the assembly process of installing the elastic valve seat 32 into the mounting hole 311, the elastic valve seat 32 can be placed into the mounting hole 311 from the side of the mounting hole 311 toward the valve core 4, that is, the elastic valve seat 32 is placed into the mounting hole 311 from the end with the larger inner diameter of the mounting hole 311, which is conducive to reducing the difficulty of installing the elastic valve seat 32. In addition, as the elastic valve seat 32 is gradually inserted into the mounting hole 311 along the direction from the valve core 4 to the valve port 12, the inner diameter of the mounting hole 311 is reduced, so that the outer peripheral wall of the elastic valve seat 32 is squeezed by the inner peripheral wall of the mounting hole 311 and tightly fits with the inner peripheral wall of the mounting hole 311, that is, an interference fit between the elastic valve seat 32 and the mounting hole 311 is achieved, so that the matching method of the elastic valve seat 32 and the mounting hole 311 is simple and the firm installation of the elastic valve seat 32 can be ensured.

[0059] According to some embodiments of the present invention, the bracket body 31 includes a plurality of sub-brackets 312 arranged along the circumference of the valve core 4, and the plurality of sub-brackets 312 are all independent molded parts and are detachably connected to the valve cover 2, and the plurality of sub-brackets 312 jointly define the limiting space 30. The circumference of the valve core 4 here refers to the direction in which the valve core 4 rotates. In other words, the plurality of sub-brackets 312 surround the outer peripheral side of the valve core 4, and the valve core 4 is rotatable relative to the arrangement direction of the plurality of sub-brackets 312, and the plurality of sub-brackets 312 are fixed to the valve cover 2 to form the bracket body 31. Therefore, during the assembly process of the valve cover 2, the valve core bracket 3 and the valve core 4, the plurality of sub-brackets 312 can be placed on the outer peripheral side of the valve core 4 first, and then the plurality of sub-brackets 312 can be fixed on the valve cover 2, or some of the sub-brackets 312 can be fixed on the valve cover 2 first, and then the valve core 4 can be placed between the installed sub-brackets 312 through the gaps where the sub-brackets 312 are not installed, and then the remaining sub-brackets 312 can be filled to achieve the connection between the valve core 4 and the valve cover 2. In this way, the difficulty of assembling the valve core 4 and the valve core bracket 3 can be well reduced, which is conducive to improving the assembly efficiency of the valve structure 100. In a specific example, the plurality of sub-brackets 312 are the same, which is conducive to reducing the production cost of the sub-brackets 312.

[0060] According to some embodiments of the present invention, the number of sub-brackets 312 and valve ports 12 is the same and corresponds one to one, and each sub-bracket 312 is formed with a mounting hole 311. That is, the number of sub-brackets 312, valve ports 12 and elastic valve seats 32 is the same and corresponds one to one. Thus, the gaps between the corresponding sub-brackets 312, valve ports 12 and valve core 4 can be well sealed by the elastic valve seat 32, so that when each valve port 12 is connected to the switching channel 41, the corresponding elastic valve seat 32 can be used to prevent fluid leakage, which is conducive to further improving the sealing performance of the valve structure 100. Specifically, during the assembly process of the valve cover 2, the valve core bracket 3 and the valve core 4, the elastic valve seat 32 can be first installed in the mounting hole 311 of each sub-bracket 312, and the combination of multiple sub-brackets 312 and elastic valve seats 32 can be assembled with the valve core 4, and then the multiple sub-brackets 312 can be fixed on the valve cover 2 to realize the assembly of the valve cover 2, the valve core bracket 3 and the valve core 4.

[0061] According to some embodiments of the present invention, the end of the sub-bracket 312 away from the valve cover 2 is in the shape of an arc extending circumferentially around the mounting hole 311. In other words, the end of the sub-bracket 312 away from the valve cover 2 is similar in shape to the side of the mounting hole 311 away from the valve cover 2, and both are in the shape of an arc convex in the direction away from the valve cover 2, and at the same time, the wall thickness of the side of the mounting hole 311 away from the valve cover 2 is made substantially the same. As a result, the thickness of the side wall of the mounting hole 311 away from the valve cover 2 can be reduced, which is beneficial to reducing the material input of the sub-bracket 312 and the weight of the sub-bracket 312. At the same time, the overall surface area of ​​the sub-bracket 312 can be reduced to reduce the risk of contact and friction between the valve core bracket 3 and the inner wall of the valve cavity 11 when the valve core bracket 3 is installed in the valve cavity 11.

[0062] In some examples, the number of sub-brackets 312 and valve ports 12 is the same and corresponds one to one, and each sub-bracket 312 is formed with a mounting hole 311, and one end of the sub-bracket 312 away from the valve cover 2 is in an arc shape extending circumferentially around the mounting hole 311. Thus, while reducing the difficulty of assembling the valve core 4 and the valve core bracket 3, it is helpful to reduce the production cost and weight of the sub-bracket 312 and the risk of friction with the inner wall of the valve cavity 11.

[0063] According to some embodiments of the present invention, in the axial direction of the valve core 4, a positioning groove 21 is formed on the end surface of the valve cover 2 facing the valve core 4, and the positioning groove 21 is used to accommodate one end of the sub-bracket 312 facing the valve cover 2. The axial direction of the valve core 4 here refers to the direction around which the valve core 4 rotates. In other words, the valve cover 2 and the sub-bracket 312 are plug-fitted through the positioning groove 21. As a result, the difficulty of positioning the sub-bracket 312 when it is installed on the valve cover 2 can be reduced. At the same time, by limiting the sub-bracket 312 through the positioning groove 21, the sub-bracket 312 can be prevented from being offset, which is conducive to improving the stability of the connection between the sub-bracket 312 and the valve cover 2.

[0064] According to some embodiments of the present invention, in the axial direction of the valve core 4, the end surface of the sub-bracket 312 facing the valve cover 2 is parallel to the bottom wall plane of the positioning groove 21. That is to say, in the axial direction of the valve core 4, the wall surfaces of the sub-bracket 312 and the positioning groove 21 opposite to each other are parallel to each other, so that the end surface of the sub-bracket 312 facing the valve cover 2 forms a surface contact with the bottom wall of the positioning groove 21. In this way, the contact area between the end surface of the sub-bracket 312 facing the valve cover 2 and the bottom wall of the positioning groove 21 can be increased, which is conducive to improving the connection stability between the sub-bracket 312 and the valve cover 2, and at the same time, it can better avoid the extrusion damage caused by the stress concentration in the local area. In a specific example, the cross-section of the sub-bracket 312 in the axial direction of the mounting hole 311 is U-shaped, that is, the end surface of the sub-bracket 312 facing the valve cover 2 is formed as a plane parallel to the axial direction of the mounting hole 311 and perpendicular to the axial direction of the valve core 4, and the end of the sub-bracket 312 away from the valve cover 2 is formed as an arc convex in the direction away from the valve cover 2, thereby improving the stability of the connection between the sub-bracket 312 and the valve cover 2 while reducing the material input of the sub-bracket 312.

[0065] According to some embodiments of the present invention, the projection of the end of the sub-bracket 312 facing the valve cover 2 on the reference surface coincides with the projection of the positioning groove 21 on the reference surface, and the reference surface is perpendicular to the axial direction of the valve core 4. In other words, the portion of the sub-bracket 312 inserted into the positioning groove 21 has the same shape and size as the positioning groove 21, and after the end of the sub-bracket 312 facing the valve cover 2 is inserted into the positioning groove 21, the outer peripheral wall of the sub-bracket 312 abuts against the inner peripheral wall of the positioning groove 21. In this way, the radial and circumferential shaking of the valve core 4 can be better prevented after the sub-bracket 312 is inserted into the positioning groove 21, which is conducive to improving the positioning accuracy of the positioning groove 21 to the sub-bracket 312.

[0066] In some examples, in the axial direction of the valve core 4, the end surface of the sub-bracket 312 facing the valve cover 2 is parallel to the bottom wall plane of the positioning groove 21, and the projection of one end of the sub-bracket 312 facing the valve cover 2 on the reference surface coincides with the projection of the positioning groove 21 on the reference surface, and the reference surface is perpendicular to the axial direction of the valve core 4. This helps to improve the positioning accuracy of the positioning groove 21 to the sub-bracket 312, and at the same time improves the connection stability between the sub-bracket 312 and the valve cover 2.

[0067] According to some embodiments of the present invention, the driving mechanism 5 includes: an actuator 51, a bearing 52 and a valve stem 53, the bearing 52 is arranged on the valve cover 2, the valve stem 53 is inserted through the bearing 52 and the valve cover 2, and the two ends of the valve stem 53 are respectively connected to the actuator 51 and the valve core 4. In other words, the bearing 52 is rotatable relative to the bearing 52, and the actuator 51 is connected to the valve core 4 through the valve stem 53, so that the valve stem 53 can be driven by the actuator 51 to rotate and drive the valve core 4 to rotate, so as to control the on-off, reversing or flow regulation of the fluid in the pipeline. In a specific example, a slot 42 is formed on the valve core 4, and the end of the valve stem 53 away from the actuator 51 is plugged into the slot 42, which is conducive to simplifying the matching structure of the valve stem 53 and the valve core 4.

[0068] In a specific example, the actuator 51 includes a stepper motor, a relief hole 23 is formed on the valve cover 2, at least part of the bearing 52 is inserted into the relief hole 23, the valve stem 53 is rotatably inserted into the bearing 52, one end of the valve stem 53 away from the valve core 4 extends out of the bearing 52 and the valve cover 2 and is sleeved with a transmission gear 54, the actuator 51 drives the transmission gear 54 to rotate through the stepper motor output torque, and drives the valve core 4 to rotate through the valve stem 53. Among them, an annular seal 6 is provided between the valve cover 2 and the valve body 1, between the bearing 52 and the valve cover 2, and between the bearing 53 and the valve stem 53 to ensure the sealing performance of the valve structure 100.

[0069] The following describes a thermal management system according to an embodiment of a second aspect of the present invention with reference to the accompanying drawings.

[0071] According to the thermal management system of the embodiment of the second aspect of the present invention, according to the valve structure 100 of the embodiment of the present invention, the valve core bracket 3 is arranged on the valve cover 2 and is located in the valve cavity 11, and the valve core 4 is rotatably arranged on the valve core bracket 3 and is located in the valve cavity 11, so that during the assembly process of the valve structure 100, the combination of the valve cover 2, the valve core bracket 3 and the valve core 4 can be directly inserted into the valve cavity 11, which is conducive to simplifying the assembly steps of the valve structure 100. At the same time, the assembly of the valve cover 2, the valve core bracket 3 and the valve core 4 can be carried out outside the valve cavity 11, which can ensure that the valve cover 2, the valve core bracket 3 and the valve core 4 have sufficient assembly space, which is conducive to reducing the assembly difficulty of the valve structure 100 to improve the assembly efficiency of the valve structure 100, and in the process of later maintenance of the valve structure 100, after the valve cover 2 is removed from the valve body 1, the valve core 4 can be pulled out of the valve cavity 11 together, which is convenient for inspection, replacement and other operations of the valve core 4, which is conducive to reducing the maintenance difficulty of the valve structure 100.

[0072] According to some embodiments of the present invention, the valve body 1 is a valve island, so that multiple valve structures 100 can share the same valve island, that is, multiple valve structures 100 can be integrated on the same valve island to improve the integration of the thermal management system.
