[0002] A multi-way valve is a mechanical device used to control the flow of liquid or gas. The multi-way valve achieves the connection of different interfaces on the valve body through different flow channel designs on the valve core surface.

[0003] In the prior art, the flow channel of the drum-type multi-way valve mainly adopts a single-layer design, all of which surround the surface of the cylindrical valve core. This design can only connect adjacent interfaces, and has great limitations in realizing multiple modes. It is limited to the one-dimensional arrangement and connection possibility. The interface array on the valve body requires a large number of rows or columns, resulting in a large diameter or length of the valve body and the valve core, large volume and heavy weight, and a complicated overall structure, high cost, and poor economic efficiency. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a multi-way valve to reduce its volume.

[0005] In order to achieve the above-mentioned purpose and other related purposes, the utility model provides a multi-way valve, comprising:

[0010] In an optional embodiment of the present invention, a cavity is provided in the valve core, a partition is provided in the cavity, and the partition divides the cavity into at least two independent common cavities.

[0011] In an optional embodiment of the present utility model, when the valve core is located at one working position, when the valve core is switched to each working position, each of the flow channels is connected to two of the interfaces or is not connected to any of the interfaces.

[0012] In an optional embodiment of the present invention, the first type of flow channel is an open groove with a notch facing the valve body, and the notch of the open groove is arranged to extend along the axial direction or circumferential direction of the valve core.

[0013] In an optional embodiment of the present invention, a mounting plane is provided on a side of the valve body away from the chamber, and the interface is provided on the mounting plane.

[0014] In an optional embodiment of the present invention, the interfaces are arranged in an array on the valve body.

By setting two layers of flow channels, the utilization rate of the space on the valve core can be improved, thereby reducing the volume of the multi-way valve. At the same time, the use of the second type of flow channels can connect non-adjacent interfaces, which can increase the number of connection combinations and achieve more connection modes with fewer interfaces. As the number of interfaces decreases, the volume of the multi-way valve can also be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0037] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0038] The drum type multi-way valve is used to control the flow direction of liquid or gas in a pipeline system. It includes a rotating valve core 20 similar to a drum, which has multiple channels and can be rotated as needed to change the flow direction of the fluid. It is usually composed of a valve body 70, a valve core 20 and an operating mechanism. The valve body 70 is the main part of the multi-way valve, usually made of plastic, metal or alloy, and has an inlet and an outlet connected to the pipeline system. The valve core 20 is a key component of the multi-way valve, usually a cylindrical or spherical part, which contains channels for controlling the flow. The operating mechanism can be manual (such as a handle or gear) or automatic (such as an electric or pneumatic actuator), which is used to rotate the valve core 20 to change the flow direction of the fluid.

[0039] The existing drum-type multi-way valve has an open flow channel, which is located on the surface of the valve core 20, and the flow channel position of the valve core 20 corresponds to the input port one by one. Limited by the spatial structure, in order to realize the connection between two access ports, the two access ports must be adjacent; if they are not adjacent, the two ports cannot be connected and opened; therefore, the number of mode combinations that can be realized by this valve is relatively small. At the same time, in order to realize all mode combinations, the traditional multi-way drum valve has to use blind ports (occupying positions but not flowing, which will increase the number of columns) when designing the access port topology, and increase the number of rows to the third row, the fourth row or even more, to adjust and increase the possibility of the access port being adjacent to other access ports. The more rows and columns of the access ports, the larger the space occupied by the corresponding valve core 20 in each mode, and the larger the volume of the valve core 20 required. Therefore, the fewer rows and columns, the smaller the volume of the valve. The increase in invalid access ports will greatly increase the volume of the multi-way valve.

[0040] like Figure 1 , 2 As shown in , 4 , the utility model provides a multi-way valve, including a valve body 70 and a valve core 20 .

[0041] The valve body 70 is provided with a chamber 71, and the surface of the valve body 70 is provided with a plurality of interfaces 30 communicating with the chamber 71. The chamber 71 is connected to an external pipeline system through the plurality of interfaces 30 on the surface of the valve body 70, so that fluid can enter or leave the valve body 70, thereby realizing control and distribution of the fluid.

[0042] like Figure 2 As shown, a mounting plane 72 is provided on one side of the valve body 70 away from the chamber 71, and the interface 30 is provided on the mounting plane 72. The mounting plane 72 on the valve body 70 is a relatively flat surface, which is convenient for fixing the entire valve body 70 to a bracket, a base, a module or other supporting structure to ensure the stability and reliability of the valve body 70. By providing the interface 30 on the flat mounting plane 72, it is easier to connect the valve body 70 to a pipeline system or other equipment. These interfaces 30 can be designed as threads, flanges or other connection methods to ensure a safe and sealed connection to prevent fluid leakage.

[0043] like Figure 2 As shown, the interfaces 30 are arranged in an array on the valve body 70. Through the array arrangement, the interfaces 30 can be arranged more compactly on the surface of the valve body 70, so that the entire valve structure is more compact and fits into a smaller space. At the same time, the interfaces 30 are arranged according to a certain rule, so that the interfaces 30 can be distinguished and found more quickly, and the operator can find them more easily for operation.

[0044] like Figure 2As shown, the interfaces 30 are provided in two rows, and the interfaces 30 in the same row are arranged along the axial direction of the valve core 20. Too many rows of interfaces 30 will increase the volume of the valve, and if there is only one row of interfaces 30, the pipelines can only be interconnected in the row, and the number of combinations is small, making it difficult to achieve switching of multiple modes.

[0045] The valve core 20 is installed in the chamber 71. A plurality of flow channels are provided on the valve core 20. The valve core 20 is movably connected to the valve body 70 so that the valve core 20 can switch between at least two different positions. When the valve core 20 is located at different positions, at least two of the interfaces 30 are connected through the flow channels. When the valve core 20 switches positions, different flow channels will work alternately. When the flow channels work, they can connect to the corresponding interfaces 30, thereby realizing the switching of the multi-way valve mode. When the valve core 20 is located in one position, some flow channels are in an open state, allowing fluid to pass through and connect to the corresponding interfaces 30. When switching to another working position, other flow channels will open, and at the same time, the flow channels in the previous position will be blocked by the inner wall of the cavity, thereby changing the path and connection method of the fluid.

[0046] like Figure 1 , 2 As shown in , 4, the valve core 20 is a cylindrical structure, and the chamber 71 is a cylindrical cavity that matches the valve core 20. The cylindrical valve core 20 and the chamber 71 cooperate to provide better sealing performance and reduce fluid leakage. The rotational drive mechanism of the cylindrical valve core 20 is relatively simple, easy to design and manufacture, and helps to reduce the complexity of parts. At the same time, the rotational drive of the cylindrical valve core 20 is easy to integrate with other systems, and can be conveniently switched by mechanical means or electric drive. In addition, the cylindrical valve core 20 is easy to switch by rotational drive, and the rotational motion is usually more reliable, can provide a long-lasting service life, and reduce the wear of the valve core 20 when switching. Rotational motion can usually provide smoother operation, which helps to reduce shock and vibration in the system.

[0047] like Figure 1 As shown, an inner sealing gasket 40 is provided between the valve core 20 and the interface 30. The inner sealing gasket 40 can fill the gap between the valve core 20 and the interface 30, ensuring that the valve can be completely sealed in a closed state to prevent fluid leakage.

[0048] like Figure 2As shown, an outer sealing gasket 50 is arranged at a position corresponding to the interface 30 on the mounting plane 72. That is, an outer sealing gasket 50 is arranged between the interface 30 and the pipeline or module in the thermal management system. The outer sealing gasket 50 is usually made of a soft material, such as rubber or silicone. At the same time, all interfaces 30 share one outer sealing gasket 50, and holes are opened on the outer sealing gasket 50 corresponding to each interface 30. By sharing one outer sealing gasket 50, the valve structure is more concise, and the number and complexity of parts are reduced.

[0049] like Figure 1 , 4 As shown, the axial end of the valve core 20 is provided with a drive shaft 24, the axial end of the chamber 71 is provided with an end cover 73, the side of the end cover 73 away from the chamber 71 is provided with a drive device 60, and the drive shaft 24 passes through the end cover 73 and is in transmission connection with the drive device 60. The end cover 73 is a component installed at the axial end of the chamber 71, which is used to seal the chamber 71 and provide support. The drive device 60 is used to control the switch or adjustment of the valve, and usually includes an electric drive, a pneumatic drive or a manual device. The drive shaft 24 is a transmission component connecting the valve core 20 and the drive device 60, and is used to transmit the power of the drive device 60 to the valve core 20 to control the movement of the valve.

[0050] The overall drive device 60 of the present application is preferably provided with a motor and a gear train. Figure 3 As shown, the drive device 60 is connected to the end cover 73 by a connecting bolt 74, the end cover 73 is provided with a connecting bolt 74, and the drive device 60 is provided with a bolt hole 61 connected and matched with the connecting bolt 74. The drive device 60 is provided with a positioning hole, and the end cover 73 is provided with a positioning pin, and the positioning hole and the positioning pin form a plug-in fit. The end faces of the drive device 60 and the end cover 73 are sealed by a sealing ring. The end cover 73 and the valve body 70 are preferably connected by laser welding or bolts. The drive shaft 24 extends into the drive device 60 through the hole on the valve cover and cooperates with the gear system through a spline. When the motor rotates, the torque is transmitted through the gear system to drive the valve core 20 to rotate. The drive shaft 24 in the valve body 70 is sealed with the outer side of the valve body 70 through an X-shaped sealing ring 75.

[0051] like Figure 5 As shown, the flow channel includes a first type of flow channel 21 and a second type of flow channel, wherein the first type of flow channel 21 is located on the surface of the valve core 20, the second type of flow channel is located inside the valve core 20, and the end opening 23 of the second type of flow channel is located on the surface of the valve core 20, the first type of flow channel 21 is configured to connect two adjacent interfaces 30, and the second type of flow channel is configured to connect two non-adjacent interfaces 30. By arranging two layers of flow channels on the valve core 20, more flow channel connections can be achieved in a limited space, thereby improving the utilization rate of the space on the valve core 20.

[0052] This design allows the valve to achieve complex fluid control functions in a relatively small volume. Effective use of the space on the valve core 20 not only improves space utilization, but also reduces the volume of the entire valve. Compared with traditional designs, this two-layer flow channel design can reduce the size and weight of the valve while maintaining functionality, thereby saving installation space and material costs. The use of the second type of flow channel can achieve connectivity between non-adjacent interfaces 30, thereby increasing the number of connectivity combinations of the valve. This means that the valve can achieve more different fluid transmission modes, improving its flexibility and applicability. Since the design of the second type of flow channel allows connectivity between non-adjacent interfaces 30, fewer interfaces 30 can be used to achieve more connectivity modes. This design not only simplifies the structure of the valve, but also reduces manufacturing costs and reduces the complexity of the system.

[0053] like Figure 5 As shown, the first type of flow channel 21 is an open groove with a notch facing the valve body 70, and the notch of the open groove is arranged along the axial direction or circumferential direction of the valve core 20. The open groove can accommodate fluid and guide its flow. When the valve core 20 is located at the corresponding position, the notch of the open groove can cover two adjacent interfaces 30, and then the two interfaces 30 can be connected through the groove cavity of the open groove. The notch extending axially can connect the interfaces 30 adjacent in the axial direction, and the notch extending circumferentially can connect the interfaces 30 adjacent in the circumferential direction.

[0054] like Figure 5 As shown, the outer peripheral wall of the valve core 20 except the first type of flow channel 21 and the end opening 23 is a smooth arc surface. The smooth outer peripheral wall can reduce the friction and resistance on the surface of the valve core 20, thereby reducing the wear on the surface of the valve core 20 and extending the service life of the valve. At the same time, the arc-shaped outer peripheral wall can provide better sealing performance and reduce the risk of fluid leakage.

[0055] like Figure 4 As shown, a cavity is provided in the valve core 20, and a partition 25 is provided in the cavity, and the partition 25 divides the cavity into at least two independent common cavities 22. Since the second type of flow channel is a dark flow channel structure, it is difficult to process directly, so the second type of flow channel is divided into a common cavity 22 and an end opening 23. The common cavity 22 is set as an open structure on the partition 25, and the common cavity 22 is directly integrated on the partition 25, avoiding the complicated dark flow channel processing process on the body 26. Such a design simplifies the manufacturing process, reduces the difficulty and cost of processing, and improves production efficiency. After the body 26 is sleeved on the partition 25, the body 26 can close the open structure, and only the end opening 23 on the body 26 is retained for communication. This design ensures that the second type of flow channel can still effectively achieve fluid communication after the valve core 20 is assembled.

[0056] In an optional embodiment of the utility model, a common cavity 22 is provided between at least two of the second-type flow channels. The common cavity 22 is a hole or groove provided in the center of the valve core 20, and the common cavity 22 can be shared by all the second-type flow channels, which is convenient for the processing of the valve core. That is, when the valve core 20 is located at different workstations, the end openings 23 of different groups are connected respectively, and the end openings 23 of different groups share the same common cavity 22. By sharing the same common cavity 22, the number of flow channels that need to be provided on the valve core 20 is reduced, and the structure of the valve core 20 is simplified. In this way, the manufacturing cost can be reduced, the volume can be reduced, and the manufacturing efficiency can be improved.

[0057] All the second-type flow channels can share the same common cavity 22. That is, only one common cavity 22 is retained, and then multiple end openings 23 are opened. The connection of different interfaces 30 is achieved by opening and closing the end openings 23, so that the switching of different modes can be completed only through the same common cavity 22. Using only one common cavity 22 simplifies the structure of the valve core 20 and reduces the number and complexity of flow channels. This can reduce manufacturing costs, improve reliability, and reduce the complexity of maintenance. At the same time, the single common cavity 22 design may take up less space. Simplified structure usually means easier maintenance. The number and complexity of components are reduced, and maintenance personnel can more easily inspect, clean and repair valves.

[0058] In an optional embodiment of the utility model, when the valve core 20 is switched to each workstation, each of the flow channels is connected to two of the interfaces 30 or is not connected to any of the interfaces 30. That is, the openings at both ends of the first type of flow channel 21 and the second type of flow channel used to connect the interfaces 30 are simultaneously connected to the interfaces 30 or are closed at the same time. This prevents one of the openings of the first type of flow channel 21 and the second type of flow channel from being connected to the interface 30 while the other opening is closed to the interface 30, thereby causing the first type of flow channel 21 and the second type of flow channel to be connected to a single port and forming a blind port. By avoiding the formation of a blind port, the diameter or length of the multi-way valve can be reduced, thereby reducing the volume and weight of the multi-way valve, simplifying the overall structure and reducing costs, while improving the efficiency and performance of the system, simplifying the flow channel connection logic, and making it easier to design the position of the flow channel.

[0059] When the valve core 20 is located at different workstations, different groups of end openings 23 and first-class flow channels 21 can be shared. By sharing the end openings 23 and the first-class flow channels 21, the number of openings on the valve core 20 can be reduced, thereby saving space. For application scenarios with limited space, this design can make the valve more compact and easier to install and arrange. Reducing the number of end openings 23 simplifies the structure of the valve core 20 and reduces the number and complexity of parts. This helps to reduce manufacturing costs, improve manufacturing efficiency, and reduce the complexity of maintenance. Fewer openings means fewer processing and assembly steps, thereby reducing manufacturing costs. In addition, a simpler structure may also reduce the procurement cost of parts. The design of sharing the end openings 23 allows the valve core 20 to switch more flexibly between different workstations, thereby achieving fluid control in different modes.

[0060] Taking the ten-way valve as an example, the interfaces 30 are numbered as port 1, port 2, port 3, port 4, port 5, port 6, port 7, port 8, port 9, and port 10. The area where the corresponding interface 30 is located is the working area. When the valve core 20 rotates to switch different working positions, the first type of flow channel 21 and the end opening 23 on it enter the working area in turn, and the first type of flow channel 21 and the end opening 23 entering the working area are connected to the corresponding interface 30.

[0061] The multi-way valve in this application can be switched and used in the following seven modes.

[0062] Mode 1, such as Figure 6 As shown, the first first-class flow channel 21 in the working area on the valve core 20 connects the No. 2 port 2 and the No. 10 port 10; the second first-class flow channel 21 connects the No. 3 port 3 and the No. 9 port 9; the third first-class flow channel 21 connects the No. 1 port 1 and the No. 4 port 4; the two end openings 23 are connected to the common cavity 22 of the valve core 20 to form a dark flow channel, connecting the No. 5 port 5 and the No. 6 port 6.

[0064] Mode three, such as Figure 8 As shown, the first first-class flow channel 21 in the working area on the valve core 20 connects the No. 5 port 5 and the No. 9 port 9; the second first-class flow channel 21 connects the No. 1 port 1 and the No. 4 port 4; the two end openings 23 are connected to the common cavity 22 of the valve core 20 to form a dark flow channel, connecting the No. 6 port 6 and the No. 8 port 8.

[0065] Mode 4, such as Fig. 9 As shown, the first first-class flow channel 21 in the working area on the valve core 20 connects the No. 2 port 2 and the No. 9 port 9; the second first-class flow channel 21 connects the No. 3 port 3 and the No. 10 port 10; the third first-class flow channel 21 connects the No. 1 port 1 and the No. 4 port 4; the two end openings 23 are connected to the common cavity 22 of the valve core 20 to form a dark flow channel, connecting the No. 5 port 5 and the No. 6 port 6.

[0066] Mode 5, such as Fig.10 As shown, the first first-class flow channel 21 in the working area on the valve core 20 connects the number five port 5 and the number nine port 9; the second first-class flow channel 21 connects the number one port 1 and the number eight port 8; the third first-class flow channel 21 connects the number six port 6 and the number seven port 7; the two end openings 23 are connected to the common cavity 22 of the valve core 20 to form a dark flow channel, connecting the number four port 4 and the number ten port 10.

[0067] Mode six, such as Fig.11 As shown, the first first-class flow channel 21 in the working area on the valve core 20 connects the No. 5 port 5 and the No. 9 port 9; the second first-class flow channel 21 connects the No. 1 port 1 and the No. 8 port 8; and the third first-class flow channel 21 connects the No. 4 port 4 and the No. 6 port 6.

[0068] Mode 7, such as Fig.12 As shown, the first first-class flow channel 21 in the working area on the valve core 20 connects the number five port 5 and the number nine port 9; the second first-class flow channel 21 connects the number one port 1 and the number four port 4; the two end openings 23 are connected to the common cavity 22 of the valve core 20 to form a dark flow channel, connecting the number three port 3 and the number six port 6.

[0069] A vehicle thermal management system includes the above-mentioned multi-way valve, and the valve core 20 is switched at different workstations to achieve connectivity between different coolant circuits in the thermal management system. By using a multi-way valve and an adjustable valve core 20, the connectivity status of different coolant circuits can be flexibly adjusted and controlled according to the actual working conditions and needs of the vehicle, thereby achieving precise control of the vehicle thermal management system. At the same time, different coolant circuits can be selectively connected or disconnected as needed to avoid unnecessary energy consumption, improve the energy efficiency performance of the system, and optimize the thermal management effect of the vehicle. In addition, the use of a multi-way valve and an adjustable valve core 20 can reduce the number of valves and pipes required in the system, simplify the system structure, and reduce the cost of components and maintenance costs.

[0070] In summary, the utility model proposes a multi-way valve and a vehicle thermal management system. By setting two layers of flow channels, the utilization rate of the space on the valve core 20 can be improved, thereby reducing the volume of the multi-way valve. At the same time, the use of the second type of flow channels can connect non-adjacent interfaces 30, which can increase the number of connection combinations. Fewer interfaces 30 can be used to achieve more connection modes. As the number of interfaces 30 decreases, the volume of the multi-way valve can also be reduced.
