[0002] In automotive thermal management, water valves are required to switch the water circuit on and off and adjust the opening to achieve temperature regulation at various locations of the vehicle. As a device for controlling the flow direction and flow rate of the heat exchange medium, the four-way valve is installed between the circuits of each module. The four-way valve usually has at least one fluid channel on the valve core, and the two ends of the fluid channel are connected to the liquid inlet and the liquid outlet respectively.

The first valve body 20 and the second valve body 30 enclose a cavity 11, which is conducive to providing a housing space for the valve core 40, so that the valve core 40 can be accommodated in the cavity 11. The first valve body 20 and the second valve body 30 are both rotatably connected to the valve core 40, that is, the valve core 40 can rotate relative to the first valve body 20 and the second valve body 30.

The valve core shaft 50 is used to drive the valve core 40 to rotate around the valve core shaft 50. One end of the valve core shaft 50 is connected to the first valve body 20, and the other end extends from the second valve body 30. The end of the valve core shaft 50 extending from the second valve body 30 is used to connect to a driving member, so that the driving member can control the rotation of the valve core 40, thereby realizing the valve switching to different passages.

[0044] Optionally, the valve further includes a bearing 51, a bearing 51 groove is provided on the first valve body 20, the bearing 51 is accommodated in the bearing 51 groove, and one end of the valve core shaft 50 connected to the first valve body 20 is connected to the bearing 51. The valve further includes a guide seal ring 52 and a spacer ring 53, the guide seal ring 52 and the spacer ring 53 are sleeved on the valve core shaft 50, the guide seal ring 52 and the spacer ring 53 are arranged between the valve core 40 and the second valve body 30, the number of the guide seal ring 52 is two, the spacer ring 53 is sandwiched between the two guide seal rings 52, and the spacer ring 53 is fixedly connected to the valve core shaft 50, so that the sealing performance of the valve core shaft 50 and the second valve body 30 is achieved, and the guide seal ring 52 is prevented from moving along the axial direction of the valve core shaft 50 through the spacer ring 53, and it is beneficial to reduce the friction during the rotation of the valve core shaft 50.

[0045] The first valve body 20 is provided with a first liquid inlet 22, and the second valve body 30 is provided with a first flow channel 32. The cavity 11 includes a first liquid outlet cavity 341 and a second liquid outlet cavity 342. The first liquid outlet cavity 341 and the second liquid outlet cavity 342 are separated from each other. The first flow channel 32 is communicated with the first liquid outlet cavity 341 and the second liquid outlet cavity 342 respectively. The first flow channel 32 is used to input liquid into the second valve body 30, and the first liquid outlet cavity 341 and the second liquid outlet cavity 342 are both used to output liquid to the outside of the valve, so that the first valve body 20 is used for liquid inlet, and the liquid flows through the valve core 40 and then flows out from the second valve body 30. In addition, the liquid entering the valve can flow out from the first liquid outlet cavity 341 and the second liquid outlet cavity 342 respectively through the first flow channel 32.

[0046] It can be understood that the cavity 11 can also include a third liquid outlet cavity, the first liquid outlet cavity 341, the second liquid outlet cavity 342 and the third liquid outlet cavity are separated from each other, and the first flow channel 32 and the third liquid outlet cavity are connected, so that the liquid entering the valve can flow out from the first liquid outlet cavity 341, the second liquid outlet cavity 342 and the third liquid outlet cavity respectively through the first flow channel 32. That is, the cavity 11 can be divided into at least two liquid outlet cavities, and at least two liquid outlet cavities are connected to the first flow channel 32, so that the valve can realize the functions of a two-way valve, a three-way valve, a four-way valve, a five-way valve, or even more ports.

[0047] Optionally, the first liquid outlet cavity 341 has a first liquid outlet, and the second liquid outlet cavity 342 has a second liquid outlet. The liquid entering the valve enters the first liquid outlet cavity 341 through the first flow channel 32, and then flows out through the first liquid outlet; the liquid entering the valve enters the second liquid outlet cavity 342 through the first flow channel 32, and then flows out through the second liquid outlet.

[0048] The valve core 40 is accommodated in the cavity 11 formed by the first valve body 20 and the second valve body 30. The valve core 40 separates the first liquid inlet 22 and the first flow channel 32, so that after the liquid enters the valve, it passes through the valve core 40 and then passes through the first flow channel 32, and then enters the first liquid outlet cavity 341 and / or the second liquid outlet cavity 342 through the first flow channel 32. The valve core 40 has a first valve core cavity 44, and a first through hole 441 is provided on the inner wall of the first valve core cavity 44. The first through hole 441 is used to communicate with the first flow channel 32, so that after the liquid enters the valve through the first liquid inlet 22, it enters the first valve core cavity 44, and then communicates with the first flow channel 32 through the first through hole 441, and the liquid enters the first liquid outlet cavity 341 and / or the second liquid outlet cavity 342. By making the valve meet the above structure, the flow path mode of the valve is more diversified, and it is conducive to simplifying the design and reducing the manufacturing cost.

[0049] The first valve body 20 and the second valve body 30 are both rotatably connected to the valve core 40, so that the valve core 40 controls the first opening 441 and the first flow channel opening 32 to be connected or disconnected during the rotation process, thereby controlling whether the liquid can enter the first liquid outlet cavity 341 and / or the second liquid outlet cavity 342 through the first flow channel opening 32. At the same time, the valve changes the area ratio of the first opening 441 connected to the first liquid outlet cavity 341 and the second liquid outlet cavity 342 respectively by rotation, so that the area ratio of the first opening 441 connected to the first liquid outlet cavity 341 and the second liquid outlet cavity 342 respectively can change linearly, thereby realizing linear adjustment of the liquid outlet ratio between the first liquid outlet cavity 341 and the second liquid outlet cavity 342.

[0050] During the rotation process, the valve core 40 can control the first liquid outlet cavity 341 and the second liquid outlet cavity 342 to be closed, one of the first liquid outlet cavity 341 and the second liquid outlet cavity 342 to be opened, and the ratio of the liquid flow rate flowing out of the first liquid outlet cavity 341 and the second liquid outlet cavity 342 to change, thereby realizing a variety of flow path modes, which is conducive to the valve being suitable for a wider variety of application scenarios; and the valve has a simple structure, and simple changes based on the above structure can also realize the function of a valve with more openings, thereby realizing a more diversified flow path mode of the valve and reducing the manufacturing cost of the valve.

[0051] The valve provided in the present application includes a first valve body 20, a second valve body 30 and a valve core 40. The first valve body 20 and the second valve body 30 are connected and enclosed to form a cavity 11. The valve core 40 is located between the first valve body 20 and the second valve body 30 and is accommodated in the cavity 11. The first valve body 20 is provided with a first liquid inlet 22, and the second valve body 30 is provided with a first flow channel 32. The cavity 11 includes a first liquid outlet cavity 341 and a second liquid outlet cavity 342 separated from each other. The first flow channel 32 is communicated with the first liquid outlet cavity 341 and the second liquid outlet cavity 342 respectively, so that the first valve body 20 is used for liquid inlet, and the liquid flows through the valve core 40, and then flows out from the first liquid outlet cavity 341 and the second liquid outlet cavity 342 respectively through the first flow channel 32.

[0052] By making the first valve body 20 and the second valve body 30 both rotatably connected to the valve core 40, the valve core 40 can control the first port 441 and the first flow channel 32 to be connected or disconnected during rotation, thereby controlling whether the liquid can enter the first liquid outlet chamber 341 and / or the second liquid outlet chamber 342 through the first flow channel 32, and can control the change in the ratio of liquid flow rates flowing out of the first liquid outlet chamber 341 and the second liquid outlet chamber 342, thereby realizing a variety of flow path modes, which is conducive to the valve being suitable for a wider range of application scenarios; and the structural design of the valve can meet the functions of a valve with more ports, which is conducive to reducing the manufacturing cost of the valve.

[0053] In one implementation, see Figure 1 , Figure 2 , Figure 6 and Figure 8 The second valve body 30 has a partition structure 34 therein, which partitions the first liquid outlet cavity 341 and the second liquid outlet cavity 342. The extension direction of at least part of the partition structure 34 forms an angle with the rotational circumference of the valve core 40, so that at least part of the first liquid outlet cavity 341 and at least part of the second liquid outlet cavity 342 are distributed along the rotational circumference of the valve core 40, thereby realizing that during the rotation of the valve core 40, the first opening 441 is connected with the first liquid outlet cavity 341 and the second liquid outlet cavity 342 in sequence.

[0054] The number of the first flow channel openings 32 is at least two, and the at least two first flow channel openings 32 are distributed along the rotation circumference of the valve core 40, wherein the distances between the at least two first flow channel openings 32 and the rotation axis of the valve core 40 can be the same or different, and there is only a single first flow channel opening 32 on any rotation radius of the valve core 40.

[0055] At least one first flow channel opening 32 is connected to the first liquid outlet cavity 341 and contacts the partition structure 34, and at least one first flow channel opening 32 is connected to the second liquid outlet cavity 342 and contacts the partition structure 34, so that when the valve core 40 rotates to the point where the first opening 441 and the partition structure 34 are relative, the first opening 441 can be connected to the first liquid outlet cavity 341 and the second liquid outlet cavity 342 at the same time, thereby achieving the change of the liquid inlet ratio between the first liquid outlet cavity 341 and the second liquid outlet cavity 342 by rotating the valve core 40.

[0056] Optionally, the first liquid outlet chamber 341 has two first flow channel openings 32 spaced apart from each other, and the second liquid outlet chamber 342 has two first flow channel openings 32 spaced apart from each other, and one first flow channel opening 32 in the first liquid outlet chamber 341 and one first flow channel opening 32 in the second liquid outlet chamber 342 are respectively located on both sides of the partition structure 34, so that when the valve core 40 rotates in a certain direction, liquid discharges from the first liquid outlet chamber 341, the valve closes, the first liquid outlet chamber 341 and the second liquid outlet chamber 342 discharge liquid in a certain ratio, the valve closes, liquid discharges from the second liquid outlet chamber 342, and the valve closes.

[0057] In one implementation, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The first valve body 20 also includes a second liquid inlet 23, and a second flow channel 33 is provided on the second valve body 30. The second flow channel 33 is used to communicate with the second liquid outlet chamber 342. The valve core 40 also includes a second valve core chamber 45. The second valve core chamber 45 is separated from the first valve core chamber 44. A second through port 451 is provided on the inner wall of the second valve core chamber 45. The second through port 451 is used to communicate with the second liquid inlet 23 and the second flow channel 33, so that the valve is a four-way valve, and liquid can enter the valve through the second liquid inlet 23, and then the second through port 451 and the second liquid inlet 23 are connected to enter the second valve core chamber 45 by rotating the valve core 40, and then enter the second liquid outlet chamber 342 through the second flow channel 33; or, liquid can enter the valve through the second liquid inlet 23, and then enter the second valve core chamber 45, and then the second through port 451 and the second flow channel 33 are connected to enter the second liquid outlet chamber 342 by rotating the valve core 40.

[0058] Optionally, the first liquid inlet 22 and the second liquid inlet 23 of the first valve body 20 operate independently, and when the second liquid inlet 23 takes in liquid, the first liquid inlet 22 stops taking in liquid or the first flow channel 32 is blocked, and the water flow of the first valve body 20 only flows out through the second liquid outlet cavity 342 of the second valve body 30; when the first liquid inlet 22 takes in liquid, the second liquid inlet 23 stops taking in liquid or the second flow channel 33 is blocked, so that the first flow channel 32 and the second flow channel 33 cannot take in liquid at the same time, thereby preventing the liquid in the second flow channel 33 from interfering with the liquid inlet ratio between the first liquid outlet cavity 341 and the second liquid outlet cavity 342 controlled by the first flow channel 32.

[0059] In one implementation, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 When the valve core 40 rotates to the first position, the first opening 441 is connected to the first liquid inlet 22 and the first flow channel opening 32 respectively, and the first flow channel opening 32 is connected to the first liquid outlet cavity 341, so that all the liquid entering the valve flows out from the first liquid outlet cavity 341.

[0060] When the valve core 40 rotates to the second position, the first opening 441 is connected to the first liquid inlet 22 and the first flow channel opening 32 respectively, and the first flow channel opening 32 is connected to the second liquid outlet cavity 342, so that all the liquid entering the valve flows out from the second liquid outlet cavity 342.

[0061] The first position and the second position are spaced apart, and the valve core 40 is used to rotate between the first position and the second position to adjust the ratio of the first communication area to the second communication area, the first communication area is the communication area between the first through port 441 and the first liquid outlet cavity 341, and the second communication area is the communication area between the first through port 441 and the second liquid outlet cavity 342. That is, the ratio of the areas of the first through port 441 communicating with the first liquid outlet cavity 341 and the second liquid outlet cavity 342 is controlled.

[0062] Optionally, when the valve core 40 rotates clockwise from the first position to the second position, the valve core 40 rotates a first angle, and the first angle is less than 360°. When the angle at which the valve core 40 rotates clockwise from the first position is less than the first angle, the first through port 441 is connected to both the first liquid outlet chamber 341 and the second liquid outlet chamber 342 at the same time, that is, the liquid entering the valve enters the first liquid outlet chamber 341 and the second liquid outlet chamber 342 at the same time through the first flow channel 32; and the ratio of the areas at which the first through port 441 is connected to the first liquid outlet chamber 341 and the second liquid outlet chamber 342 respectively changes with the change of the angle at which the valve core 40 rotates clockwise from the first position, that is, the ratio of the liquid entering the first liquid outlet chamber 341 and the second liquid outlet chamber 342 at the same time is different when the angle at which the valve core 40 rotates clockwise from the first position is different, thereby achieving control of the liquid flow ratio flowing out of the first liquid outlet chamber 341 and the second liquid outlet chamber 342. When the valve core 40 rotates clockwise from the first position to an angle greater than the first angle and less than 360°, the first opening 441 is blocked from the first liquid outlet cavity 341 and the second liquid outlet cavity 342 , that is, the liquid entering the valve cannot flow out.

[0063] In one implementation, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 When the valve core 40 rotates to the third position, the second opening 451, the second flow channel opening 33 and the second liquid inlet 23 are connected, so that the liquid can enter the valve through the second liquid inlet 23. When the valve core 40 rotates to the third position, the liquid enters the second liquid outlet cavity 342 through the second opening 451 and the second flow channel opening 33.

[0064] Optionally, the third position, the first position, and the second position are all separated by a distance. Optionally, when the valve core 40 rotates clockwise, the valve core 40 passes through the first position, the second position, and the third position in sequence. When the valve core 40 rotates clockwise from the first position to the second position, the valve core 40 rotates by a first angle, and when the valve core 40 rotates clockwise from the second position to the third position, the valve core 40 rotates by a second angle, and the sum of the first angle and the second angle is less than 360°.

[0065] When the valve core 40 rotates to the first position or the second position, at least one of the second flow channel opening 33 and the second liquid inlet 23 is blocked with the second through port 451, so that when the liquid entering the valve enters the first liquid outlet cavity 341 and / or the second liquid outlet cavity 342 through the first flow channel opening 32, the liquid cannot enter the second liquid outlet cavity 342 through the second flow channel opening 33; when the valve core 40 rotates to the third position, at least one of the first flow channel opening 32 and the first liquid inlet 22 is blocked with the first through port 441, so that when the liquid entering the valve enters the second liquid outlet cavity 342 through the second flow channel opening 33, the liquid cannot enter the first liquid outlet cavity 341 and / or the second liquid outlet cavity 342 through the first flow channel opening 32. The first liquid inlet 22 and the second liquid inlet 23 work independently by controlling the rotation of the valve core 40, so that the valve can independently switch all passages.

[0066] It can be understood that when the angle of the valve core 40 rotating clockwise from the first position is less than the first angle, that is, when the liquid entering the valve enters the first liquid outlet cavity 341 and the second liquid outlet cavity 342 through the first flow channel opening 32 at the same time, at least one of the second flow channel opening 33 and the second liquid inlet 23 is blocked by the second opening 451, and the liquid cannot enter the second liquid outlet cavity 342 through the second flow channel opening 33.

[0067] In one implementation, see Figure 1 The valve core 40 includes a first partition plate 41, a second partition plate 42 and a third partition plate 43. The first partition plate 41 and the second partition plate 42 are parallel or inclined to each other. The first partition plate 41 and the second partition plate 42 are spaced apart. The third partition plate 43 is connected between the first partition plate 41 and the second partition plate 42. The shapes of the first partition plate 41 and the third partition plate 43 are both annular. The third partition plate 43 separates the second valve core cavity 45 and the first valve core cavity 44, so that the third partition plate 43 separates the second valve core cavity 45 and the first valve core cavity 44 on the inner and outer sides, thereby making the first valve core cavity 44 and the second valve core cavity 45 independent of each other, and during the rotation of the valve core 40, the positions of the first valve core cavity 44 and the second valve core cavity 45 remain unchanged, which is conducive to simplifying the switching process of different valve passages.

[0068] Correspondingly, the first port 441 is disposed on the first partition plate 41 , so that the first port 441 is connected to the first valve core chamber 44 , and the second port 451 is disposed on the second partition plate 42 , so that the second port 451 is connected to the second valve core chamber 45 .

[0069] In one implementation, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The first valve body 20 has a first accommodating chamber 21, and the second partition 42 and part of the third partition 43 are accommodated in the first accommodating chamber 21. Part of the bottom wall of the first accommodating chamber 21 abuts against the surface of the second partition 42 facing away from the first partition 41. The second liquid inlet 23 is located on the bottom wall of the first accommodating chamber 21 abutting against the second partition 42, so that the second partition 42 exists between the second liquid inlet 23 and the second valve core chamber 45. When the valve core 40 is rotated to connect the second through port 451 with the second liquid inlet 23, the liquid can enter the second valve core chamber 45 from the second liquid inlet 23.

[0070] The first liquid inlet 22 is located on the bottom wall of the first accommodating chamber 21 separated from the second partition 42, so that part of the bottom wall of the first accommodating chamber 21 separated from the first partition 41, the side wall of the first accommodating chamber 21, the second partition 42, and the third partition 43 together enclose the first valve core chamber 44. Therefore, the first liquid inlet 22 is always connected to the first valve core chamber 44, so that the rotating valve core 40 only controls the first port 441 and the first flow channel port 32 to be connected or blocked.

[0071] Optionally, the valve also includes a first valve body sealing ring 25, and the bottom wall of the first accommodating chamber 21 is provided with a groove, the groove surrounds the edge of the second partition 42, and the first valve body sealing ring 25 is accommodated in the groove and abuts against the second partition 42 to seal between the second partition 42 and the first valve body 20, thereby ensuring the sealing between the first valve core chamber 44 and the second valve core chamber 45.

[0072] Optionally, the first valve body 20 has a first liquid inlet chamber and a second liquid inlet chamber, the first liquid inlet chamber and the second liquid inlet chamber are located on the side of the first valve body 20 facing away from the valve core 40, the first liquid inlet port 22 is used to connect the first liquid inlet chamber and the first valve core chamber 44, and the second liquid inlet port 23 is used to connect the second liquid inlet chamber and the second valve core chamber 45; the valve also includes a lower cover, the lower cover is located on the side of the first valve body 20 facing away from the valve core 40, the lower cover and the first valve body 20 are sealed and connected, and after the lower cover and the first valve are installed, the first liquid inlet chamber and the second liquid inlet chamber are sealed apart.

[0073] Optionally, the first valve body 20 has an installation cavity 24, a gasket 241 and a sealing ring 242, the number of the installation cavity 24 is at least two, the gasket 241 and the sealing ring 242 correspond to the installation cavity 24 one by one, the sealing ring 242 and the gasket 241 are both accommodated in the installation cavity 24, the gasket 241 and the second partition 42 are abutted, wherein the surface of the gasket 241 in contact with the valve core 40 is smooth, which is beneficial to reducing the friction of the rotation of the valve core 40, thereby facilitating the valve to switch different passages.

[0074] At least two mounting cavities 24 are evenly distributed around the rotation axis of the valve core 40, so that the friction force when the valve core 40 rotates is evenly distributed, which is beneficial to prevent the valve core 40 from being eccentric during the rotation process, thereby ensuring the reliability of the valve. The edge of the second liquid inlet 23 has a single mounting cavity 24, and the mounting cavity 24 has a sealing ring 242, so that the edge of the second liquid inlet 23 has good sealing performance, which is beneficial to prevent the liquid in the second liquid inlet 23 from flowing to other positions of the first accommodating cavity 21.

[0075] In one implementation, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The second valve body 30 has a second accommodating chamber 31, the opening of the second accommodating chamber 31 and the opening of the first accommodating chamber 21 are arranged opposite to each other, the first partition 41 and part of the third partition 43 are accommodated in the second accommodating chamber 31, part of the bottom wall of the second accommodating chamber 31 abuts against the surface of the first partition 41 facing away from the second partition 42, and the second flow channel opening 33 is located on the bottom wall of the second accommodating chamber 31 separated from the first partition 41. Since the first partition 41 is annular in shape, the middle part of the bottom wall of the second accommodating chamber 31 is separated from the first partition 41, so that the middle part of the bottom wall of the second accommodating chamber 31, the first partition 41 and the third partition 43 jointly enclose the second valve core chamber 45, so that the second flow channel opening 33 is always connected to the second liquid outlet chamber 342 and the second valve core chamber 45, so that the rotating valve core 40 only controls the second port 451 and the second liquid inlet 23 to be connected or blocked.

[0076] The first flow channel opening 32 is located on the bottom wall of the second accommodating chamber 31 which is abutted against the first partition plate 41, so that there is a first partition plate 41 between the first flow channel opening 32 and the first valve core chamber 44. When the valve core 40 is rotated to connect the first opening 441 and the first flow channel opening 32, the liquid can enter the first liquid outlet chamber 341 from the first flow channel opening 32.

[0077] Optionally, the valve further includes a valve core seal 46, which is annular in shape and is located between the first partition plate 41 and the bottom wall of the second accommodating chamber 31. The valve core seal 46 and the valve core 40 form a cross-sectional seal, which is beneficial to improving the sealing performance between the valve core 40 and the second valve body 30. The positions of the valve core seal 46 and the second valve body 30 are relatively fixed, and the valve core seal 46 is provided with a through hole corresponding to the first flow channel opening 32, thereby ensuring that the liquid flows between the valve core 40 and the second valve body 30.

[0078] Optionally, the valve further includes a second valve body sealing ring 35, which is disposed between the first valve body 20 and the second valve body 30 to seal the first valve body 20 and the second valve body 30. The valve further includes an upper cover, which is located on a side of the second valve body 30 facing away from the valve core 40, and the upper cover is sealed to the second valve body 30. After the upper cover and the second valve are installed, the first liquid outlet cavity 341 and the second liquid outlet cavity 342 are sealed at intervals.

[0079] Optionally, there are multiple second flow channel openings 33, and the multiple second flow channel openings 33 are evenly spaced around the rotation axis of the valve core 40. Since the second flow channel openings 33 are always connected to the second liquid outlet cavity 342 and the second valve core cavity 45, increasing the number of second flow channel openings 33 can increase the opening area of ​​the second flow channel openings 33, which is beneficial to increase the flow rate of liquid entering the second liquid outlet cavity 342 when liquid is taken in by the second liquid inlet 23, thereby improving the liquid outlet rate of the second liquid outlet cavity 342.

[0080] In one implementation, see Figure 7 and Figure 8 The second opening 451 passes through the valve core 40 in the direction from the second partition plate 42 to the first partition plate 41, and the inner wall of the second opening 451 encloses a second valve core cavity 45, so that the second valve core cavity 45 forms a pipeline structure, thereby reducing the volume of the second valve core cavity 45, which is beneficial to avoid turbulence of the liquid in the second valve core cavity 45 and reduce the flow rate, and is beneficial to increase the liquid outlet rate of the second liquid outlet cavity 342.

[0081] One end of the second valve core chamber 45 is located on the plane where the first partition 41 is located, and the other end is located on the plane where the second partition 42 is located, so that after the liquid enters the second valve core chamber 45 from the second liquid inlet 23, it directly enters the second flow channel 33 along the pipeline structure formed by the second valve core chamber 45, so that the movement direction of the liquid in the second valve core chamber 45 remains consistent, further avoiding turbulence of the liquid in the second valve core chamber 45 and reducing the flow rate, which is beneficial to improving the liquid outlet rate of the second liquid outlet chamber 342.
