Description

Technical Field

[0001] This invention relates to the field of control valve technology, and in particular to a multi-way valve. Background Technology

[0002] With the development of new energy vehicle technology, automotive thermal management systems are becoming increasingly complex, involving a wider range of thermal management components. The thermal management of components such as batteries and motors, combined with traditional passenger compartment and engine thermal management, makes the operation of thermal management systems increasingly complex. Traditional thermal management solutions require more and more piping and valves. This excessive number of components not only makes the thermal management system overly complex and difficult to install, but also increases the likelihood of system failure.

[0003] To address the above issues, automotive thermal management will further develop towards integration and modularization. Water-side integration is a crucial component of integrated thermal management, and multi-way valves are core components of water-side integration modules. Through various combinations of multi-way valves, different water circuit connections can be achieved, enabling different functions such as waste heat recovery and battery cooling. Therefore, it is necessary to provide a multi-way valve to overcome the aforementioned shortcomings. Summary of the Invention

The valve block rotates synchronously with the valve disc. The valve disc includes a first flow groove connecting two adjacent flow channel cavities. The valve block includes a first flow channel for connecting two flow channel cavities with connecting ports.

[0009] The valve core can be driven to rotate between multiple positions, thereby connecting different flow channels and switching the flow mode.

When the port of the first flow channel is located between two adjacent connecting ports and is not connected to any flow channel cavity, the third flow groove is connected to two adjacent flow channel cavities.

[0014] Preferably, the multi-way valve further includes a first sealing gasket disposed at the bottom of the first receiving groove and in contact with the valve disc, and a second sealing gasket disposed on the side wall of the second receiving groove and in contact with the valve block.

[0015] Preferably, the edge of the valve block away from the cover plate protrudes in a direction away from the cover plate to form a convex ring, the bottom of the second receiving groove is provided with a sealing plate, and a plurality of limiting blocks are provided on the sealing plate along the circumferential direction, and the convex ring is engaged between the limiting blocks and the second sealing gasket.

[0039] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0040] See Figures 1 to 4 This embodiment discloses a multi-way valve, which is installed on a heat management water plate. The multi-way valve includes a housing 1, a cover plate 2, a valve core 3, and an actuator 4. The housing 1 is cylindrical, and the circumferential wall of the housing 1 extends outward to provide mounting ears 16 for fixing the multi-way valve to the heat management water plate. The housing 1 includes a first receiving groove 11 and a second receiving groove 12, with the second receiving groove 12 located at the bottom of the first receiving groove 11 and coaxially arranged with it. Both the first receiving groove 11 and the second receiving groove 12 are cylindrical, and the diameter of the first receiving groove 11 is larger than the diameter of the second receiving groove 12. A sealing plate 121 is provided at the bottom of the second receiving groove 12. Preferably, the sealing plate 121 is integrally formed with the housing 1. The outer surface of the circumferential wall of the housing 1 is vertically provided with fixing ears 14 for fixing the cover plate 2. The fixing ears 14 also serve as reinforcing ribs 21, improving the overall structural strength of the multi-way valve.

[0041] See Figure 5 and Figure 6 The housing 1 also includes multiple flow channel cavities that are not interconnected. These flow channel cavities are located at the bottom of the first receiving groove 11 and are evenly spaced around the second receiving groove 12. At least two flow channel cavities have communication ports 15 with the second receiving groove 12. A third sealing gasket 7 is provided between the housing 1 and the heat management water plate. The flow channel cavities axially penetrate and connect the heat management water plate and the first receiving groove 11, and a valve port communicating with the heat management water plate is provided at the bottom of the flow channel cavity.

[0042] See Figure 10 The cover plate 2 is located on the top of the housing 1, specifically on top of the first receiving groove 11. Both the inner and outer surfaces of the cover plate 2 are provided with reinforcing ribs 21. A guide plate 22 extends from the inner surface of the cover plate 2 towards the side where the flow channel cavity is located, and the guide plate 22 is arranged circumferentially. A sealing ring 8 is fitted onto the guide plate 22, and the sealing ring 8 is located between the guide plate 22 and the circumferential wall of the housing 1.

[0043] See Figure 8 and Figure 9The valve core 3 is rotatably disposed within the housing 1. The valve core 3 includes a valve disc 31 placed within a first receiving groove 11, a valve block 32 coaxially disposed with the valve disc 31 and placed within a second receiving groove 12, and a drive shaft 314 protruding from the valve disc 31 towards the side away from the valve block 32. The valve block 32 rotates synchronously with the valve disc 31. The drive shaft 314 passes through the cover plate 2 and connects to the actuator 4. A first sealing gasket 5 is provided at the bottom of the first receiving groove 11, contacting the valve disc 31. This provides excellent sealing, preventing internal and external leakage. In this embodiment, the valve disc 31 is disc-shaped, and the valve block 32 is cylindrical. Preferably, the valve disc 31 and the valve block 32 are integrally formed.

[0044] The valve disc 31 includes a first flow groove 311 connecting two adjacent flow channel cavities, and the valve block 32 includes a first flow channel 321 for connecting two flow channel cavities with connecting ports 15. A second sealing gasket 6 is provided in the second receiving groove 12, and the second sealing gasket 6 is disposed on the side wall of the second receiving groove 12 and in contact with the valve block 32. The upper surface of the first sealing gasket 5 and the inner surface of the second sealing gasket 6 are both coated with a coating, which can greatly reduce friction and reduce the torque required for the valve core 3 to rotate.

[0045] See Figure 7 The valve block 32 has a protruding ring 322 on its edge away from the cover plate 2. Multiple limiting blocks 122 are provided circumferentially on the sealing plate 121. The protruding ring 322 is engaged between the limiting block 122 and the second sealing gasket 6 to limit the valve block 32 during installation and ensure radial stability during rotation. In this embodiment, the side of the limiting block 122 that contacts the protruding ring 322 is arc-shaped. In other embodiments, it can also be chamfered, as long as the protruding ring 322 and the limiting block 122 are in surface-to-line contact.

[0046] See Figure 2 and Figure 4 In this embodiment, preferably, the multi-way valve is a six-way valve, including six flow channel chambers: a first flow channel 321 chamber a, a second flow channel chamber b, a third flow channel chamber c, a fourth flow channel chamber d, a fifth flow channel chamber e, and a sixth flow channel chamber f. The housing 1 also includes a first valve port 131 communicating with the first flow channel 321 chamber a, a second valve port 132 communicating with the second flow channel chamber b, a third valve port 133 communicating with the third flow channel chamber c, a fourth valve port 134 communicating with the fourth flow channel chamber d, a fifth valve port 135 communicating with the fifth flow channel chamber e, and a sixth valve port 136 communicating with the sixth flow channel chamber f. The first valve port 131, the second valve port 132, the third valve port 133, the fourth valve port 134, the fifth valve port 135, and the sixth valve port 136 are all located on the same plane and connect the heat management water plate to the corresponding flow channel chamber.

[0047] See Figures 6 to 9Each of the first flow channel 321 cavity a to the sixth flow channel cavity f has a connecting port 15 between itself and the second receiving groove 12. The valve plate 31 also includes a second flow groove 312 and a third flow groove 313. The first flow groove 311 and the second flow groove 312 are arranged in a counterclockwise direction from the third flow groove 313. The first flow channel 321 is a straight flow channel, and the first flow groove 311 and the second flow groove 312 are respectively arranged on both sides of the valve block 32 and are symmetrically arranged about the first flow channel 321. The third flow groove 313 is located at one end of the length direction of the first flow channel 321, and the second flow groove 312 is also used to connect two adjacent flow channel cavities. The cross-section of the flow channel cavity is fan-shaped, and the cross-sections of the first flow groove 311, the second flow groove 312, and the third flow groove 313 are all fan-shaped.

[0048] When the first flow channel 321 is rotated to face two oppositely arranged connecting ports 15, the third flow groove 313 is directly connected to one of the six flow channel cavities. When the port of the first flow channel 321 is located between two adjacent connecting ports 15 and is not connected to any flow channel cavity, the third flow groove 313 connects to two adjacent flow channel cavities. In one rotation, the flow channel cavities connected to the first flow channel 321, the first flow groove 311, and the second flow groove 312 are all different. Furthermore, different rotation angles can be set according to the actual needs of the thermal management system to shield unnecessary connection methods.

[0049] See Figure 2 The flow channels of the multi-way valve are arranged clockwise as follows: first flow channel 321 a, fourth flow channel d, third flow channel c, sixth flow channel f, second flow channel b, and fifth flow channel e. Under the control of the actuator 4, the valve core 3 can be driven to rotate between multiple positions, realizing the connection of different flow channels and thus switching the flow mode.

[0050] See Figure 11 The multi-way valve includes 5 flow modes:

[0051] Mode 1: When the valve core 3 rotates to the point where both ends of the first flow channel 321 are directly aligned with the first flow channel 321 cavity a and the sixth flow channel cavity f, the first flow channel 321 connects the first flow channel 321 cavity a and the sixth flow channel cavity f, the first flow groove 311 connects the fifth flow channel cavity e and the second flow channel cavity b, and the second flow groove 312 connects the fourth flow channel cavity d and the third flow channel cavity c.

[0052] Mode 2: When the valve core 3 rotates to the point where both ends of the first flow channel 321 are directly opposite the fourth flow channel cavity d and the second flow channel cavity b, the first flow channel 321 connects the fourth flow channel cavity d and the second flow channel cavity b, the first flow groove 311 connects the first flow channel 321 cavity a and the fifth flow channel cavity e, and the second flow groove 312 connects the third flow channel cavity c and the sixth flow channel cavity f.

[0053] Mode 3: When the valve core 3 rotates to the point where both ends of the first flow channel 321 are directly opposite the fifth flow channel cavity e and the third flow channel cavity c, the first flow channel 321 connects the fifth flow channel cavity e and the third flow channel cavity c, the first flow groove 311 connects the second flow channel cavity b and the sixth flow channel cavity f, and the second flow groove 312 connects the first flow channel 321 cavity a and the fourth flow channel cavity d.

[0054] Mode 4: When the valve core 3 rotates to the position where the port of the first flow channel 321 directly faces the third flow groove 313 and is located between the connecting port 15 of the first flow channel 321 cavity a and the connecting port 15 of the fifth flow channel cavity e, both ends of the first flow channel 321 are blocked by the second sealing gasket 6 and are not connected to any flow channel cavity. The third flow groove 313 connects the first flow channel 321 cavity a and the fifth flow channel cavity e, the first flow groove 311 connects the second flow channel cavity b and the sixth flow channel cavity f, and the second flow groove 312 connects the third flow channel cavity c and the fourth flow channel cavity d.

[0055] In mode 5, when the valve core 3 rotates to the position where the port of the first flow channel 321 directly faces the third flow groove 313 and is located between the connecting port 15 of the first flow channel 321 cavity a and the connecting port 15 of the fourth flow channel cavity d, both ends of the first flow channel 321 are blocked by the second sealing gasket 6 and are not connected to any flow channel cavity. The third flow groove 313 connects the first flow channel 321 cavity a and the fourth flow channel cavity d, the first flow groove 311 connects the second flow channel cavity b and the fifth flow channel cavity e, and the second flow groove 312 connects the third flow channel cavity c and the sixth flow channel cavity f.

[0056] It will be apparent to those skilled in the art that various modifications and variations can be made to the exemplary embodiments described above without departing from the spirit and scope of the invention. Therefore, it is intended that this invention cover modifications and variations falling within the scope of the appended claims and their equivalents.
