[0001] The present application relates to the field of automotive thermal management, and in particular to a one-way valve and an integrated assembly. Background Art
[0002] In related technologies, the inner seal of a one-way valve is mostly sealed by an O-ring in conjunction with the valve body wall. However, the sealing ring will frequently rub against the valve body wall as the valve core moves, which can easily lead to problems such as the sealing ring falling out and failing, thereby causing fluid leakage. Utility Model Content
[0003] One purpose of the present application is to provide a one-way valve and an integrated assembly that can reduce the risk of the sealing ring coming out.

When the abutted area remains unchanged, the axial length of the seal is greater than the radial length of the seal. Compared with the technical solution in which the radial dimension of the seal is greater than the axial dimension, the radial space occupied by the seal is smaller, thereby increasing the diameter of the through hole, and then increasing the flow area of the fluid flowing through the through hole, thereby reducing the flow resistance of the one-way valve.

Compared with the technical solution in which the radial dimension of the seal is greater than the axial dimension, the radial space occupied by the seal is smaller, thereby increasing the diameter of the through hole, and then increasing the flow area of the fluid flowing through the through hole, thereby reducing the flow resistance of the one-way valve.

DETAILED DESCRIPTION
[0017] The embodiments are described in detail below with reference to the accompanying drawings.
[0018] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and specific embodiments. In this document, relational terms such as "first" and "second" are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.
[0019] like Figure 8 As shown, the integrated assembly 400 includes a flow channel plate 200, which has a flow channel 300 for liquid flow. A one-way valve 100 is embedded in the flow channel 300 to control the flow direction of the fluid. The one-way valve 100 includes a first valve body 1, a second valve body 2, and a valve core 4. When the one-way valve 100 is located in the flow channel 300, fluid flows in from the first valve body 1 and out from the second valve body 2. The valve core 4 is located in the one-way valve 100. When fluid flows from the first valve body 1 to impact the valve core 4, the fluid is forward-conducted. When fluid flows from the second valve body 2 to impact the valve core 4, the fluid is blocked by the valve core 4 and cannot be reverse-conducted. In this way, the one-way valve 100 can control the flow direction of the fluid in one direction. The direction of forward fluid flow is defined as positive, the surface facing the fluid outflow direction is the top surface, and the surface facing the fluid inflow direction is the bottom surface. The axial direction of the one-way valve is defined as the direction of valve core movement.
[0020] like Figure 3 As shown, the one-way valve 100 also includes a sealing member 3, which has a through hole 33, and the valve core 4 can close the through hole 33; when the fluid flows in the forward direction, the fluid enters the through hole 33 and impacts the valve core 4, and the valve core 4 moves and allows the fluid to pass through the through hole 33; when the fluid flows in the reverse direction or the one-way valve 100 is in a static state, the valve core 4 abuts against the sealing member 3, closing the through hole 33 to prevent the fluid from flowing in the reverse direction.
[0021] like Figure 3 As shown, one side of the seal 3 abuts against the first valve body 1, and the other side of the seal 3 abuts against the second valve body 2; further, along the axial direction of the one-way valve 100, a part of the seal 3 abuts against the first valve body 1, and a part of the seal 3 abuts against the second valve body 2; along the radial direction of the one-way valve 100, a part of the seal 3 abuts against the first valve body 1, and a part of the seal 3 abuts against the second valve body 2, and parts of the four sides of the seal 3 abut against the first valve body 1 and the second valve body 2, which enhances the stability of the seal 3, makes the seal 3 not easy to fall out, and can also reduce leakage at the connection between the first valve body 1 and the second valve body 2.
[0022] like Figure 3 As shown, the length along the axial direction of the one-way valve 100 is defined as the axial length, and the length along the radial direction of the one-way valve 100 is defined as the radial length. At least a portion of the seal 3 is located radially outside the first valve body 1, and part of the inner wall of the seal 3 abuts against the outer wall of the first valve body 1. The axial length of the seal 3 is greater than the radial length of the seal 3. At least a portion of the seal is located outside the first valve body, and a portion of the seal is blocked by the first valve body, reducing the risk of the seal 3 falling out radially inward.
[0023] like Figure 3 As shown, the seal 3 has a through hole 33, and the valve core 4 is capable of closing the through hole 33. The seal 3 is abutted by the first valve body 1 and the second valve body 2. When the abutted area remains unchanged, the axial length of the seal 3 is greater than the radial length of the seal 3. Compared with the technical solution in which the radial dimension of the seal 3 is greater than the axial dimension, the radial space occupied by the seal 3 is smaller, thereby increasing the diameter of the through hole 33, thereby increasing the flow area of the fluid flowing through the through hole 33, and thus reducing the flow resistance of the one-way valve 100.
[0024] like Figure 3 and Figure 5-Figure 7 As shown, specifically, the seal 3 includes a valve opening 32 and a clamping portion 34. The wall of the valve opening 32 includes a wall forming a through hole 33, and at least a portion of the valve core 4 can abut against the valve opening 32. The clamping portion 34 extends from the valve opening 32 toward the outside of the first valve body 1. Along the axial direction of the one-way valve 100, one side of the clamping portion 34 abuts against the first valve body 1, and the other side of the clamping portion 34 abuts against the second valve body 2. The clamping portion 34 is abutted by the first valve body 1 and the second valve body 2 on both sides of the axial direction, enhancing the stability of the seal 3, preventing it from falling out, and reducing leakage at the connection between the first valve body 1 and the second valve body 2.
[0025] like Figure 5-Figure 7 As shown, the first valve body 1 includes a port portion 11, the port portion 11 has a channel 16 extending along the axial direction of the one-way valve 100, and the channel 16 has an opening 111 at one axial end of the port portion 11. The seal 3 includes an extension portion 31, at least part of the extension portion 31 is located on the outside of the port portion 11, that is, the extension portion 31 is sleeved on the outside of the first valve body 1, and the inner side wall of the extension portion 31 abuts against the outer side wall of the port portion 11. The extension portion 31 of the seal 3 is located on the outer side wall of the valve body, which enhances the stability of the seal 3 and reduces the risk of the seal 3 falling out radially inward, making it difficult for the seal 3 to fall out.
[0026] Furthermore, the length along the axial direction of the one-way valve 100 is defined as the axial length, and the length along the radial direction of the one-way valve 100 is defined as the radial length. The axial length of the extension portion 31 is greater than the radial length of the extension portion 31. Preferably, the axial length of the extension portion 31 is greater than or equal to three times the radial length. In this case, when the area of the extension portion 31 abutted remains unchanged, the contact area between the extension portion 31 and the first valve body 1 is larger, and the sealing effect is better. During the research process, the inventor found that when the area of the extension portion 31 clamped remains unchanged, the technical solution in which the axial length of the extension portion 31 is greater than the radial length is compared to the technical solution in which the radial dimension of the extension portion 31 is greater than the axial dimension. The radial space occupied by the extension portion 31 of this solution is smaller, thereby increasing the diameter of the through hole 33 of the valve mouth portion 32, thereby improving the flow efficiency of the one-way valve 100 at the through hole 33.
[0027] like Figure 7 As shown, the seal 3 is generally L-shaped. While the area of the extension 31 held in place remains unchanged, the axial length of the extension 31 is longer, increasing the friction between the seal 3 and the first valve body 1. This allows the seal 3 to be positioned more stably and prevents it from slipping out radially from the inside. Furthermore, the longer sealing surface also provides a better sealing effect, significantly reducing leakage. Furthermore, the inventors discovered during their research that increasing the flow efficiency of a fluid through a one-way valve can be achieved by increasing the flow area of the fluid. However, when the one-way valve is embedded in the flow channel 300 of the integrated assembly, the inner diameter of the flow channel 300 is fixed. In this case, increasing the flow area of the fluid within the flow channel can only be achieved by reducing the wall thickness of the one-way valve. Therefore, while the area of the extension 31 held in place remains unchanged, reducing the radial thickness of the extension 31 can reduce the overall wall thickness of the one-way valve 100. The thinner the wall, the larger the area of fluid flow and the higher the flow efficiency.
[0028] Along the radial direction of the one-way valve 100, the inner diameter of the through hole 33 is greater than or equal to the inner diameter of the opening 111, that is, the inner diameter of the valve mouth portion 32 is greater than or equal to the diameter of the valve mouth, so as to prevent the valve mouth portion 32 from protruding from the valve mouth, causing the flow at the valve mouth to be disturbed, and then causing the valve mouth flow to decrease.
[0029] The second valve body 2 includes a bracket 23, most of the valve core 4 is located on the radial inner side of the bracket 23, and a part of the valve core 4 slides with the bracket 23, which can limit the movement of the valve core 4, prevent the valve core 4 from moving and rotating, and increase the operation stability of the one-way valve 100; the radial dimension of the valve core 4 is larger than the radial dimension of the through hole 33, and the valve core 4 is larger than the size of the through hole 33 of the seal 3. When the valve core 4 is closed, the valve core can have a larger contact area with the seal 3, thereby enhancing the sealing effect.
[0030] like Figure 4-Figure 6As shown, the first valve body 1 includes a valve inlet 14, which is located at one end of the first valve body 1 relatively far away from the valve core 4, and the fluid flows into the one-way valve 100 from the valve inlet 14; the first valve body 1 includes a card slot 13, and the second valve body 2 includes a buckle 21, which is engaged with the wall forming the card slot 13. The first valve body 1 and the second valve body 2 are easily installed by being engaged. At the same time, since the sealing member 3 is located between the first valve body 1 and the second valve body 2, the first valve body 1 and the second valve body 2 are a detachable connection structure, which facilitates the installation and disassembly of the sealing member 3.
[0031] like Figure 5-Figure 7 As shown, along the axial direction of the one-way valve 100, the extension portion 31 extends from the clamping portion 34 to one side of the valve inlet 14. The inventors found that if the extension portion 31 extends toward the second valve body, in order to provide space for the seal 3, the thickness or length of the clamping structure will increase, thereby resulting in an increase in the overall length of the valve or a decrease in the fluid outlet area. The extension portion 31 extends from the valve mouth portion 32 toward the flow inflow direction, which can make full use of the space of the first valve body 1 itself and reduce the thickness of the first valve body 1 by embedding it in the first valve body 1. In the flow channel 300, the thinner the valve wall, the larger the area of fluid circulation and the higher the flow efficiency.
[0032] Further, such as Figure 5 As shown, the first valve body 1 includes a raised portion 12 that protrudes from the outer wall of the port portion 11. The outer diameter of the raised portion 12 gradually increases toward the valve inlet 14, forming a sloped surface that serves as a sliding guide during installation of the clip 21, facilitating the engagement of the clip 21. The outer diameter of the extension portion 31 is less than or equal to the minimum outer diameter of the raised portion 12 to avoid interference with the installation of the clip 21.
[0033] like Figure 4-Figure 6 As shown, the slot 13 is located on the side of the protrusion 12 away from the port portion 11; the second valve body 2 includes a base portion 22 and a buckle 21, and along the axial direction of the one-way valve, the buckle 21 protrudes from the bottom wall 222 of the base portion 22 to the side of the valve inlet 14, and the buckle 21 includes a connecting portion 211 and a snap-fit portion 212, the connecting portion 211 is connected to the base portion 22, and the snap-fit portion 212 is connected to the connecting portion 211; along the axial direction of the one-way valve 100, one side of the extension portion 31 abuts the protrusion 12, and the other side of the extension portion 31 abuts the bottom wall 222 of the base portion 22; along the radial direction of the one-way valve 100, one side of the extension portion 31 abuts the axial outer side wall of the port portion 11, and the other side of the extension portion 31 abuts the connecting portion 211. The extension portion 31 is located in the groove formed by the inner side of the buckle 21 of the second valve body 2 and the raised portion 12 of the first valve body 1. While avoiding the buckle 21, it also reasonably utilizes the space at the valve body clamping structure, reduces the volume occupied by the seal 3, reduces the thickness of the valve body, and thereby increases the circulation efficiency.
[0034] like Figure 4-Figure 6 As shown, the first valve body 1 includes at least two protrusions 12, and the protrusions 12 are distributed at intervals along the circumference of the first valve body 1. The outer wall of the protrusion 12 is part of the wall forming the slot 13. The buckle 21 is clamped on the bottom surface of the protrusion 12, and one buckle 21 corresponds to one protrusion 12 one by one. The first valve body 1 includes a rotation-stop device 15, and the rotation-stop device 15 includes a boss 151 and an accommodating groove 152. One of the first valve body 1 and the second valve body 2 is provided with the boss 151, and the other is provided with the accommodating groove 152. The boss 151 is at least partially located in the accommodating groove 152. The relative rotation of the first valve body 1 and the second valve body 2 will increase the friction with the seal 3, which may easily cause the seal 3 to twist and deform. The rotation-stop device 15 can prevent the first valve body 1 from rotating relative to the second valve body 2, reduce the friction on the seal 3, and reduce the possibility of failure of the seal 3 due to torsional deformation.
[0035] like Figure 4-Figure 6 As shown, the second valve body 2 includes a boss 151, the boss 151 is located between each two adjacent protrusions 12, and the receiving groove 152 is located between each two adjacent buckles 21; or, the first valve body 1 includes a receiving groove 152, and the second valve body 2 includes a boss 151, the boss 151 is at least partially located in the receiving groove 152, the boss 151 is located between each two adjacent buckles 21, and the receiving groove 152 is located between each two adjacent protrusions 12.
[0036] Preferably, if Figure 4-Figure 6 The two ends of the fastening portion 212 are respectively connected to the two connecting parts 211, and the buckle 21 is connected to the base 22 to form a "mouth" shape. Compared with the ordinary claw-type buckle 21, the buckle 21 is larger in size, has a wider clamping area with the protrusion 12, and is more firmly clamped. At the same time, during the installation process, the buckle 21 needs to first contact the outer side wall of the extension part 31 of the seal 3, and the buckle 21 continues to move downward, slides over the outer side wall of the extension part 31, and contacts the inclined surface included in the protrusion 12, continues to move downward, slides over the protrusion 12, and the fastening portion 212 of the buckle 21 is clamped into the clamping groove 13, completing the installation of the buckle 21. At this time, the "mouth"-shaped buckle 21 has a higher integrity, and is not prone to missing or wrong clamping problems during the clamping installation. The second valve body 2 includes at least two clips 21, and a receiving groove 152 is provided between each two clips 21. The protrusion 12 is at least partially located in the receiving groove 152. The receiving groove 152 is provided on the clip 21, and the boss 151 is provided on the first valve body 1. The reasonable use of the clip structure can reduce the spatial volume of the anti-rotation device 15, further reduce the wall thickness of the valve body of the one-way valve 100, and increase the fluid circulation efficiency.
[0037] like Figure 8 As shown, in one embodiment of the present application, along the radial direction of the one-way valve 100, the distance between the protrusion 12 and the wall forming the circulation channel 300 is less than the thickness of the snap-fit portion 212; when the one-way valve 100 is embedded in the circulation channel 300, the distance from the protrusion to the wall of the circulation channel 300 is less than the thickness of the snap-fit portion 212, which can prevent the snap-fit portion 212 from passing through the gap between the protrusion and the wall forming the circulation channel 300, thereby preventing the buckle 21 from falling out of the slot.
[0038] The second valve body 2 includes a bracket 23, a base 22, and a buckle 21. One side of the base 22 is connected to the bracket 23, and the other side of the base 22 is connected to the buckle 21. The bracket 23 includes at least two legs 231, which slide with the valve core 4 to prevent the valve core 4 from moving or rotating. The base 22 of the second valve body 2 has a chamfered surface at the fluid outflow point, which serves as a fluid guide. The inclined surface can reduce turbulence generated in the base 22 during fluid outflow, ensuring smooth fluid flow and improving fluid outflow efficiency.
[0039] It should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, it should be understood by those skilled in the art that the present invention can still be modified or replaced by equivalents, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention should be included in the scope of protection of this application.
