Description

Technical Field

[0001] The present application relates to the field of thermal management of vehicles, and in particular to a valve and a thermal management system for a vehicle including the valve. Background Art

[0002] In the prior art, valves (such as plunger valves) can be used to control the on-off and flow rate of fluids in different systems. For example, a Chinese patent with the publication number CN 218440701 U and the name "A plunger valve with a metal-coated sealing ring and a combined sealing pair" discloses such a plunger valve. Moreover, such valves are often used in thermal management systems for vehicles. In a traditional valve, a housing, a columnar valve core and a sealing gasket are included. A columnar valve chamber for accommodating the columnar valve core and the sealing gasket is formed in the housing. In the process of the columnar valve core rotating relative to the housing, the interface part of the housing realizes different connection logics, and the flow rate of the interface part can also be controlled as desired. The sealing gasket is formed in a cylindrical shape and is arranged between the housing and the columnar valve core. The sealing gasket is fixed relative to the housing and is used to achieve sealing between different logic paths between the housing and the columnar valve core.

[0003] However, the entire inner surface of the existing sealing gasket facing the cylindrical valve core realizes surface contact sealing with the cylindrical valve core, and such surface contact sealing will result in a large friction force between the sealing gasket and the cylindrical valve core during the rotation of the cylindrical valve core, thereby generating a large friction torque. In addition, since the surface area of ​​the sealing gasket and the cylindrical valve core for contact sealing is large, sometimes the contact pressure between the sealing gasket and the cylindrical valve core may be insufficient and unstable, which will result in an uncertain contact position between the sealing gasket and the cylindrical valve core during the operation of the cylindrical valve core and a loose contact with each other, thereby adversely affecting the sealing performance between the sealing gasket and the cylindrical valve core. Summary of the invention

[0004] This application is made based on the defects of the above-mentioned prior art. One purpose of this application is to provide a new valve, which can reduce the friction between the valve core and the sealing gasket during the rotation process, while improving the sealing performance between the valve core and the sealing gasket. Another purpose of this application is to provide a vehicle thermal management system including the above-mentioned valve.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions.

[0006] The present application provides a valve as follows, comprising:

[0007] A housing formed with a valve cavity and a plurality of interface portions;

[0008] a valve core at least partially received in the valve cavity, wherein the plurality of interface portions can be selectively connected during the rotation of the valve core relative to the housing; and

[0009] A sealing gasket, which is fixedly located between the valve core and the housing relative to the housing, the sealing gasket is formed with an outer sealing lip on its outer surface, the outer sealing lip protrudes toward the housing and abuts against the housing to achieve contact sealing, and the sealing gasket is formed with an inner sealing lip on its inner surface, the inner sealing lip protrudes toward the valve core and abuts against the valve core to achieve contact sealing, wherein the outer sealing lip and the inner sealing lip are arranged in pairs in the radial direction of the sealing gasket.

[0010] In an optional solution, the sealing gasket is formed with a gasket through hole communicating with the interface portion, the gasket through hole has an outer opening on the outer surface and an inner opening on the inner surface,

[0011] The outer sealing lip is configured to be continuously arranged around each of the outer openings, and the inner sealing lip is configured to be continuously arranged around each of the inner openings.

[0012] In another optional solution, a protruding height of the outer sealing lip is greater than a protruding height of the inner sealing lip.

[0013] In another optional solution, the arrangement pattern of the outer sealing lip is completely the same as the arrangement pattern of the inner sealing lip.

[0014] In another optional scheme, the sealing gasket is formed into a cylindrical shape, and the outer sealing lip includes an outer circumferential lip extending along the circumference of the sealing gasket and an outer axial lip extending along the axial direction of the sealing gasket, and the outer axial lip intersects or is connected with the outer circumferential lip, so that a plurality of separated areas are divided on the outer surface by the outer sealing lip, and the inner sealing lip includes an inner circumferential lip corresponding to the outer circumferential lip and an inner axial lip corresponding to the outer axial lip.

[0015] In another optional solution, at least a portion of the outer axial lip extends continuously along the axial direction over the entire axial length of the sealing gasket; and / or

[0016] At least a portion of the inner axial lip extends continuously along the axial direction over the entire axial length of the sealing gasket.

[0017] In another optional scheme, the sealing gasket is formed with an opening extending along the axial direction, and the shell is formed with a protrusion protruding toward the valve cavity. When the sealing gasket is installed on the shell, the protrusion is located in the opening, so that the gasket is fixed relative to the shell.

[0018] In another optional solution, the sealing gasket includes a main body and a wear-resistant portion, the wear-resistant portion is stacked with the main body, and the wear-resistant portion at least covers a portion of the sealing gasket where the inner sealing lip is formed and abuts against the valve core.

[0019] In another optional solution, the main body portion includes rubber, and the wear-resistant portion includes polytetrafluoroethylene.

[0020] The present application also provides a vehicle thermal management system as follows, comprising the valve described in any one of the above technical solutions.

[0021] By adopting the above technical solution, the present application provides a valve and a thermal management system for a vehicle including the valve. In the valve of the present application, a housing, a valve core and a sealing gasket are assembled together. The housing forms a valve cavity, and the valve core is at least partially received in the valve cavity and can rotate relative to the valve core, so that the interface part of the housing realizes different communication logics. Furthermore, the sealing gasket is received in the valve cavity and is fixed relative to the housing, and the sealing gasket not only forms an outer sealing lip on its outer surface but also forms an inner sealing lip on its inner surface. The outer sealing lip protrudes toward the housing and abuts against the housing to achieve contact sealing, and the inner sealing lip protrudes toward the valve core and abuts against the valve core to achieve contact sealing, wherein the outer sealing lip and the inner sealing lip are arranged in pairs in the radial direction of the sealing gasket.

[0022] In this way, since the so-called line contact seal is achieved between the inner sealing lip of the sealing gasket and the valve core, the contact area between the sealing gasket and the valve core is greatly reduced compared with the case where the entire inner surface and the valve core achieve surface contact seal, so that the friction between the valve core and the sealing gasket is greatly reduced during the rotation of the valve core relative to the housing and the sealing gasket. In addition, since the outer sealing lip and the inner sealing lip are formed into a convex shape and the two are arranged in pairs, it is conducive to concentrating the contact pressure at the contact part between the outer sealing lip and the housing and the contact part between the inner sealing lip and the valve core, thereby making the contact pressure at the contact part between the sealing gasket and the housing and the valve core sufficient and stable, thereby improving the sealing performance between the sealing gasket and the housing and the valve core.

[0031] The exemplary embodiments of the present application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, and are not intended to exhaust all feasible methods of the present application, nor to limit the scope of the present application.

[0032] In the present application, “circumferential direction”, “axial direction” and “radial direction” refer to the circumferential direction, axial direction and radial direction of a cylindrical sealing gasket, respectively.

[0033] Hereinafter, the structure of a valve according to an embodiment of the present application will be described in conjunction with the accompanying drawings.

[0034] like Figure 1 and Figure 2 As shown, a valve according to an embodiment of the present application includes a housing 1 , a valve core 2 and a sealing gasket 3 which are assembled together.

[0035] In this embodiment, if Figure 1 and Figure 2 As shown, the housing 1 includes a housing body 11, a cover 12 and a plurality of interface parts, and the housing body 11 and the cover 12 are fixedly connected together by a plurality of threaded connectors, so as to surround and form a cylindrical valve cavity 11c. The plurality of interface parts are formed as one body with the housing body 11, and each interface part is formed with a passage communicating with the valve cavity 11c, and different interface parts are arranged spaced apart from each other, and the passages in different interface parts can be selectively communicated when the valve core 2 rotates relative to the housing 1.

[0036] In this embodiment, if Figure 1 and Figure 2As shown, a part of the valve core 2 is received in the valve cavity 11c, and another part of the valve core 2 extends out from the valve cavity 11c. Specifically, the valve core 2 includes a valve core body 21 and a transmission rod 22 fixed to each other. The valve core body 21 is formed in a cylindrical shape, and the valve core body 21 is received in the valve cavity 11c of the housing 1. The side wall of the valve core body 21 is formed with a valve core through hole 21h having a predetermined size and shape, and these valve core through holes 21h can be selectively connected with the passages in the interface part of the housing 1 during the rotation of the valve core body 21 relative to the housing 1. In this way, during the rotation of the valve core 2 relative to the housing 1, the passages of multiple interface parts of the housing 1 can be selectively connected via the valve core through holes 21h, thereby realizing different connection logics. Furthermore, the transmission rod 22 is fixedly connected to the valve core body 21 in a coaxial manner, the transmission rod 22 extends from the valve chamber 11c and an external spline is formed at the end of the transmission rod 22 away from the valve core body 21, so that the transmission rod 22 and an external power source (such as a motor) can achieve spline matching, thereby utilizing the power source to drive the transmission rod 22 and then drive the valve core 2 to rotate.

[0037] In this embodiment, if Figures 1 to 3 As shown, the sealing gasket 3 is received in the valve cavity 11c of the housing 1 and is fixed relative to the housing 1. The sealing gasket 3 is located between the housing 1 and the valve core 2, and is used to achieve contact sealing between the housing 1 and the valve core 2. The sealing gasket 3 can be fixed to the housing 1 by means of clamping or bonding. It matches with the valve cavity 11c formed in a cylindrical shape. The sealing gasket 3 is formed in a cylindrical shape, and the sealing gasket 3 can be formed with a strip opening (strip slit) extending along the axial direction A over the entire axial length. The strip opening can penetrate the sealing gasket 3 in the radial direction R, so that the sealing gasket 3 is formed in a shape that is disconnected at the strip opening. When the sealing gasket 3 is installed inside the housing 1, the strip opening formed by the sealing gasket 3 can match the shape of the strip protrusion formed on the inner wall of the housing 1 and protruding toward the valve cavity 11c, so that the strip protrusion can be inserted into the strip opening, thereby limiting the sealing gasket 3 and making the sealing gasket 3 fixed relative to the housing 1. Furthermore, after the sealing gasket 3 is installed inside the housing 1 , the valve element 2 may be installed inside the assembly of the housing 1 and the sealing gasket 3 so that the outer sealing lip 33 of the sealing gasket 3 described below is compressed.

[0038] Furthermore, if Figure 1 and Figure 2As shown, the outer surface 3s1 of the sealing gasket 3 is the outer peripheral surface of the sealing gasket 3 facing the housing 1, that is, the outer side surface of the sealing gasket 3 in the radial direction R. The sealing gasket 3 is formed with an outer sealing lip 33 on its outer surface 3s1, and the outer sealing lip 33 protrudes toward the housing 1 and abuts against the housing 1 to achieve contact sealing. Further, the outer sealing lip 33 includes an outer circumferential lip 331 and an outer axial lip 332, the outer circumferential lip 331 extends continuously along the circumference of the sealing gasket 3 over the entire circumference, and a part of the outer axial lip 332 extends continuously along the axial direction A of the sealing gasket 3 over the entire axial length. The outer circumferential lip 331 and the outer axial lip 332 intersect with each other, so that a plurality of separated areas are divided on the outer surface 3s1 by the outer sealing lip 33, and the outer opening 3p1 of the gasket through hole 3h can be formed in these areas.

[0039] Furthermore, if Figure 1 and Figure 2 As shown, the inner surface 3s2 of the sealing gasket 3 is the inner circumferential surface of the sealing gasket 3 facing the valve core 2, that is, the inner side surface of the sealing gasket 3 in the radial direction R. The sealing gasket 3 is formed with an inner sealing lip 34 on its inner surface 3s2, and the inner sealing lip 34 protrudes toward the valve core 2 and abuts against the valve core 2 to achieve contact sealing. Further, the inner sealing lip 34 includes an inner circumferential lip 341 and an inner axial lip 342, the inner circumferential lip 341 extends continuously along the circumference of the sealing gasket 3 over the entire circumference, and a part of the inner axial lip 342 extends continuously along the axial direction A of the sealing gasket 3 over the entire axial length. The inner circumferential lip 341 and the inner axial lip 342 intersect with each other, so that a plurality of separated areas are divided on the inner surface 3s2 by the inner sealing lip 34, and the inner opening 3p2 of the gasket through hole 3h can be formed in these areas.

[0040] Furthermore, if Figure 1 and Figure 2As shown, the sealing gasket 3 is formed with a gasket through hole 3h connected to the passage of the interface part. The number of the gasket through holes 3h can be the same as the number of the interface parts, the size of the gasket through hole 3h can match the size of the passage of the interface part, and the gasket through hole 3h and the corresponding interface part are always connected. In addition, the gasket through hole 3h forms an outer opening 3p1 on the outer surface 3s1 of the sealing gasket 3 and an inner opening 3p2 on the inner surface 3s2 of the sealing gasket 3, and the outer sealing lip 33 is configured to be continuously arranged around each outer opening 3p1, and the inner sealing lip 34 is configured to be continuously arranged around each inner opening 3p2. In other words, each outer opening 3p1 and each inner opening 3p2 are surrounded by the sealing lips 33 and 34 on all sides, so that when the valve core through hole 21h of the valve core 2 is connected to the passage of the interface part via the gasket through hole 3h, the sealing lips can achieve the desired sealing effect. In addition, in order to make the opening degree of the inner opening 3p2 adjustable as the valve core 2 rotates so as to control the flow rate, the inner sealing lip 34 can be constructed to cooperate with the adjustment of the opening degree of the inner opening 3p2 and be set in the so-called proportional area to play a corresponding sealing role, thereby realizing the control of the opening degree of the inner opening 3p2.

[0041] Furthermore, if Figures 1 to 3As shown, the outer sealing lip 33 and the inner sealing lip 34 are arranged in pairs in the radial direction R, so that the arrangement pattern shape of the outer sealing lip 33 is exactly the same as the arrangement pattern shape of the inner sealing lip 34. Specifically, the outer circumferential lip 331 and the outer axial lip 332 of the outer sealing lip 33 are extended respectively and intersect with each other during the extension process, so that the outer sealing lip 33 forms a specific pattern shape. The inner circumferential lip 341 and the inner axial lip 342 of the inner sealing lip 34 are extended respectively and intersect with each other during the extension process, so that the inner sealing lip 34 also forms a specific pattern shape. When the sealing gasket 3 is unfolded along the circumferential direction, the pattern shape of the outer sealing lip 33 is the same as the pattern shape of the inner sealing lip 34, wherein the setting position of the outer circumferential lip 331 is the same as the setting position of the inner circumferential lip 341, and the setting position of the outer axial lip 332 is also the same as the setting position of the inner axial lip 342. In addition, when the sealing gasket 3 is unfolded along the circumferential direction, the length of the outer circumferential lip 331 can be equal to the length of the inner circumferential lip 341, and the width of the outer circumferential lip 331 can be unequal to the width of the inner circumferential lip 341; the length of the outer axial lip 332 can be equal to the length of the inner axial lip 342, and the width of the outer axial lip 332 can be unequal to the width of the inner axial lip 342; the height of the outer circumferential lip 331 can be greater than the height of the inner circumferential lip 341, and the height of the outer axial lip 332 can be greater than the height of the inner axial lip 342, so that the height of the outer sealing lip 33 can be greater than the height of the inner sealing lip 34. The height of the outer sealing lip 33 is the maximum protrusion in the direction perpendicular to the above-mentioned outer surface 3s1, and the height of the inner sealing lip 34 is the maximum protrusion in the direction perpendicular to the above-mentioned inner surface 3s2. In fact, the heights of the outer sealing lip 33 and the inner sealing lip 34 can be adjusted to adapt to the pressure in the valve chamber 11c. Further, a portion of the outer seal lip 33 for contact with the housing 1 is formed as a curved surface, and a portion of the inner seal lip 34 for contact with the valve element 2 is formed as a curved surface.

[0042] Furthermore, if Figure 2 and Figure 3 As shown, two outer axial lips 332 and two inner axial lips 342 are arranged between the circumferentially adjacent gasket through holes 3h, and two outer circumferential lips 331 and two inner circumferential lips 341 are arranged between the axially adjacent gasket through holes 3h. Thus, even if one layer of lips used for sealing fails, the other layer of lips still works, and such an arrangement is conducive to ensuring the sealing performance between the sealing gasket 3 and the valve core 2 and the housing 1.

[0043] Furthermore, if Figure 2 and Figure 3As shown, the sealing gasket 3 includes a main body 31 and a wear-resistant portion 32. The wear-resistant portion 32 is stacked with the main body 31 in the thickness direction, and the wear-resistant portion 32 covers the entire inner surface 3s2 of the main body 31, so that the wear-resistant portion 32 covers the portion of the sealing gasket 3 where the inner sealing lip 34 is formed, and the wear-resistant portion 32 will always be in contact with the valve core 2. In this embodiment, the main body 31 can be made of rubber, and the wear-resistant portion 32 can be made of polytetrafluoroethylene, and the main body 31 and the wear-resistant portion 32 can be formed into one piece by vulcanization molding.

[0044] In this embodiment, if Figure 1 As shown, bearings may be provided between the valve core 2 and the housing body 11 and between the valve core 2 and the cover 12, so that the valve core 2 can be supported by the two bearings. In addition, in this embodiment, the sealing gasket 3 may not be a cylindrical shape extending along the entire circumference but may have a notch, but the present application is not limited thereto, and the sealing gasket 3 may also be formed into a cylindrical shape extending along the entire circumference.

[0045] The present application also provides a vehicle thermal management system, which includes a flow control module, and the flow control module includes the valve described in the above embodiment, so that the flow control module can achieve predetermined connection logic and flow control.

[0046] The above content illustrates the technical solution of the present application, but the present application is not limited to the above embodiments, and those skilled in the art can make various modifications to the above embodiments of the present application under the guidance of the present application without departing from the scope of the present application. The following supplementary explanation is further made.

[0047] i. In the above embodiment, it is explained that the outer sealing lip 33 includes an outer circumferential lip 331 and an outer axial lip 332, and the inner sealing lip 34 includes an inner circumferential lip 341 and an inner axial lip 342, but the present application is not limited thereto. The outer sealing lip 33 and the inner sealing lip 34 may adopt other pattern shapes, as long as the sealing lips 33 and 34 meet the requirements of being arranged in pairs in the radial direction R and can achieve the sealing effect that meets some working modes of the valve. It can be understood that the outer sealing lip 33 and the inner sealing lip 34 are arranged in pairs in the radial direction R, including the case where their arrangement pattern shapes are completely the same or slightly different (for example, the circumferential size of the outer circumferential lip 331 of the outer sealing lip 33 and the corresponding inner circumferential lip 341 of the inner sealing lip 34 may be slightly different).

[0048] ii. In the above embodiment, the wear-resistant portion 32 covers the entire inner surface 3s2 of the main body portion 31 , but the present application is not limited thereto. The wear-resistant portion 32 may only cover the portion of the sealing gasket 3 where the inner sealing lip 34 is formed.

[0049] iii. It can be understood that by adopting the technical solution of the present application, the effective contact pressure between the sealing gasket 3 and the housing 1 and the valve core 2 can be greatly increased, and the contact part between the sealing gasket 3 and the housing 1 and the valve core 2 is always at the location of the sealing lips 33 and 34, and the contact pressure can be concentrated at the sealing lips 33 and 34, thereby improving the sealing performance between the sealing gasket 3 and the housing 1 and the valve core 2. In addition, since the so-called line contact seal is realized between the inner sealing lip 34 and the valve core 2, the friction between the inner sealing lip 34 and the valve core 2 is greatly reduced during the rotation of the valve core 2, which is beneficial to the rotation of the valve core 2. As a result, the service life of the valve can be improved.

[0050] iv. It can be understood that the number of sealing lips between adjacent outer openings 3p1 and inner openings 3p2 can be set as needed, and can be set to two as in the above specific embodiment, or can be set to only one or more than three. In addition, the extended shape and size of the sealing lip can also be adjusted as needed, and are not limited to the scheme described in the above specific embodiment.
