For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0061] The multi-way valve 100 according to an embodiment of the present application is described below with reference to FIG. 1 to FIG. 30 .

[0062] As shown in FIG. 1 , FIG. 3 and FIG. 4 , a multi-way valve 100 according to an embodiment of the present application includes a valve body 1 and a valve core 2 .

[0063] Specifically, as shown in Figures 2, 4 and 5, the outer contour of the valve body 1 is generally cylindrical, and the valve body 1 has an installation cavity 11. The cross-section of the installation cavity 11 is circular. The valve body 1 also has multiple flow channel cavities 12. The multiple flow channel cavities 12 are located radially outside the installation cavity 11 and are arranged at intervals along the circumferential direction of the installation cavity 11. The flow channel cavities 12 can extend along the circumferential direction of the valve body 1.

[0064] The end surface of one axial end of the valve body 1 has a plurality of first flow openings 13 and second flow openings 14 that are respectively in communication with the plurality of flow cavities 12. The peripheral wall of the mounting cavity 11 has a third flow opening 15 that is respectively in communication with the plurality of flow cavities 12. It is understandable that there are a plurality of first flow openings 13, a plurality of second flow openings 14, the plurality of second flow openings 14 being respectively in communication with the plurality of flow cavities 12, a plurality of third flow openings 15, the plurality of third flow openings 15 being respectively in communication with the plurality of flow cavities 12, the third flow openings 15 connecting the mounting cavity 11 and the flow cavity 12, and the flow cavity 12 connecting the second flow openings 14 and the third flow openings 15.

[0065] As shown in Figures 4 and 6 , the valve core 2 is rotatably disposed within the mounting cavity 11 . Along the axial direction of the valve core 2 , the valve core 2 comprises a first core segment 21 and a second core segment 22 . The first core segment 21 is disposed on a side of the second core segment 22 near the first flow passage 13 . The first core segment 21 is provided with a plurality of mutually unconnected first channels 211 , each of which can connect to at least two first flow passages 13 . The second core segment 22 is provided with a plurality of mutually unconnected second channels 221 , each of which can connect to at least two third flow passages 15 , meaning that each second channel 221 connects to at least two second flow passages 14 .

[0066] It can be understood that, as shown in Figure 6, the opening of the first channel 211 is located on the axial end face of the first core segment 21 facing the first flow channel opening 13, which facilitates the communication between the first channel 211 and the first flow channel opening 13, and the opening of the second channel 221 is located on the outer peripheral wall of the second core segment 22, which facilitates the communication between the second channel 221 and the third flow channel opening 15.

[0067] In the present application, by rotating the valve core 2, the connectivity state of the first channel 211 can be changed and the first channel 211 can be connected to different first flow channel openings 13, thereby changing the flow direction of the liquid. At the same time, the connectivity state of the second channel 221 can be changed and the second channel 221 can be connected to different third flow channel openings 15, and then the second channel 221 can be connected to different second flow channel openings 14, thereby changing the flow direction of the liquid.

[0068] In addition, it can be understood that there are multiple first flow channel openings 13, multiple second flow channel openings 14, the number of flow channel cavities 12 can be the same as the number of second flow channel openings 14, and the multiple second flow channel openings 14 are respectively connected to the multiple flow channel cavities 12 in a one-to-one manner. There are multiple third flow channel openings 15, the number of third flow channel openings 15 can be the same as the number of flow channel cavities 12, and the multiple third flow channel openings 15 are respectively connected to the multiple flow channel cavities 12 in a one-to-one manner. The third flow channel openings 15 connect the installation cavity 11 and the flow channel cavity 12, and the flow cavity 12 connects the second flow channel openings 14 and the third flow channel openings 15.

[0069] In the present application, when there is a first channel 211 that is simultaneously connected to two first flow channel openings 13, liquid can enter one of the first flow channel openings 13 from the axial end face of the valve body 1, then enter the first channel 211, and finally flow out from the other first flow channel opening 13 connected to the first channel 211, with the liquid outflow side and the liquid inflow side being on the same side. When there is a second channel 221 that is connected to two third flow channel openings 15, liquid can flow into the flow channel cavity 12 from the second flow channel opening 14 that is connected to the flow channel cavity 12 connected to the third flow channel opening 15, then flow into the second channel 221 through the third flow channel opening 15, and finally flow from the third flow channel opening 15 that is connected to the second channel 221 to the corresponding flow channel cavity 12, and then flow out from the corresponding second flow channel opening 14. The liquid outflow side and the liquid inflow side are on the same side, and at the same time, the liquid outflow side and the liquid inflow side of the first core segment 21 are on the same side as the liquid outflow side and the liquid inflow side of the second core segment 22, which facilitates the arrangement of the pipeline connected to the multi-way valve 100 and helps save space.

[0070] Among them, the second core segment 22 adopts the structural form of a column valve. When the liquid in the flow channel cavity 12 flows to the second channel 221, it flows directly into the second channel 221 along the radial direction of the valve body 1. Compared with the liquid in the flow channel cavity flowing to the side of the valve body away from the second flow channel opening and then flowing into the second channel from the axial end face of the valve core away from the second flow channel opening, the stroke is shorter, the bends are less, and the flow resistance is smaller. The first core segment 21 adopts the structural form of a disc valve, which improves space utilization, is conducive to the setting of multiple channels, and has low cost. In the present application, by making the first core segment 21 adopt the structural form of a disc valve and the second core segment 22 adopt the structural form of a column valve, not only can the space utilization be improved, which is conducive to the setting of multiple channels, but also the flow resistance can be reduced, and complex through-path requirements can be met, and the volume is small.

[0071] For example, in the examples shown in Figures 2, 7-9, and in the examples shown in Figures 18, 25-27, there are four flow channel cavities 12 spaced apart along the circumferential direction of the valve body 1, and there are four second flow channel openings 14 spaced apart along the circumferential direction of the valve body 1. Accordingly, as shown in Figures 5 and 23, there are four third flow channel openings 15 spaced apart along the circumferential direction of the valve body 1, and there are two second channels 221. Each second channel 221 has two openings located on the peripheral wall of the second core segment 22, and the four openings are spaced apart in the circumferential direction of the second core segment 22. The four third flow channel openings 15 are arranged in sequence along the circumferential direction of the valve body 1, namely, No. 1, No. 2, No. 3, and No. 4. In one state, each second channel 221 is connected to two third flow channel openings 15, with one second channel 221 connecting No. 1 and No. 2, and another second channel 221 connecting No. 3 and No. 4. When the valve core 2 is rotated to another state, one second channel 221 connects No. 2 and No. 3, and another second channel 221 connects No. 4 and No. 1, thereby changing the flow direction of the liquid. At least one of the second flow channel openings 14 can be in a blocked state, so that when at least one of the multiple second channels 221 is rotated to connect to the third flow channel opening 15 connected to the flow channel cavity 12 connected to the second flow channel opening 14, the second channel 221 is blocked and does not conduct.

[0072] For another example, in the examples shown in Figures 2, 10-13, and in the examples shown in Figures 18, 28-30, there are eight first flow channel openings 13 spaced apart along the circumferential direction of the valve body 1, and there are four first channels 211. Each first channel 211 has two openings located on the axial end face of the first core segment 21. There is a first channel 211 extending from one side of the first core segment 21 to the other side opposite to the first core segment 21, that is, the two openings of the first channel 211 are located on opposite sides of the first core segment 21, and the two openings of the remaining first channels 211 are adjacent and connected in the circumferential direction of the first core segment 21. Among them, the eight first flow channel openings 13 along the circumferential direction of the valve body 1 are No. 1, No. 2, No. 3, No. 4, No. 5, No. 6, No. 7 and No. 8 respectively. In one state, one of the first channels 211 connects No. 1 and No. 2, one of the first channels 211 connects No. 3 and No. 8, one of the first channels 211 connects No. 4 and No. 5, and one of the first channels 211 connects No. 6 and No. 7; when the valve core 2 is rotated to another state, one of the first channels 211 connects No. 2 and No. 3, one of the first channels 211 connects No. 4 and No. 1, one of the first channels 211 connects No. 5 and No. 6, and one of the first channels 211 connects No. 7 and No. 8, thereby changing the flow direction of the liquid. At least one of the first flow channel openings 13 can be in a blocked state, so that when the opening of at least one of the multiple first channels 211 is rotated to the first flow channel opening 13, the first channel 211 is blocked and does not conduct.

[0073] According to the multi-way valve 100 of the embodiment of the present application, by setting an installation cavity 11 and multiple flow channel cavities 12 in the valve body 1, setting multiple first flow channel openings 13 and second flow channel openings 14 respectively connected to the multiple flow channel cavities 12 on the end face of one axial end of the valve body 1, and setting third flow channel openings 15 respectively connected to the multiple flow channel cavities 12 on the peripheral wall of the installation cavity 11, so that the valve core 2 can be rotatably arranged in the installation cavity 11, and multiple first channels 211 that are not connected to each other are set on the first core segment 21 of the valve core 2, each first channel 211 is connected to at least two first flow channel openings 13, and multiple second channels 221 that are not connected to each other are set on the second core segment 22, each second channel 221 is connected to at least two third flow channel openings 15, so that the first core segment 21 adopts the structure of a disc valve and the second core segment 22 adopts the structure of a column valve, which can not only improve space utilization, but also be beneficial to the setting of multiple channels, and can reduce flow resistance, and can meet complex through-path requirements, and has a small volume.

[0074] In some embodiments of the present application, as shown in Figures 4, 5, and 15, a plurality of first sealing gaskets 3 are disposed between the outer peripheral wall of the valve core 2 and the inner peripheral wall of the mounting cavity 11. The plurality of first sealing gaskets 3 correspond one-to-one with the plurality of third flow passages 15, and each first sealing gasket 3 is disposed around a corresponding third flow passage 15. As a result, when the second channel 221 and the third flow passage 15 are connected, a seal between the second channel 221 and the third flow passage 15 can be achieved, thereby improving the reliability of the multi-way valve 100.

[0075] Furthermore, as shown in Figure 5 , the third flow channel opening 15 extends along the circumferential direction of the valve body 1 , thereby increasing the area of ​​the third flow channel opening 15 and ensuring smooth flow of liquid between the second channel 221 and the flow channel cavity 12 . Furthermore, as shown in Figure 5 , a reinforcing rib 151 is provided within the third flow channel opening 15 . The two ends of the reinforcing rib 151 are respectively connected to two inner walls of the third flow channel opening 15 that oppose each other along the axial direction of the valve body 1 , thereby enhancing the structural strength of the valve body 1 at the third flow channel opening 15 .

[0076] In some embodiments of the present application, as shown in Figures 9 and 15, the length of the third flow channel opening 15 along the circumferential direction of the valve body 1 is greater than the length of the opening of any second channel 221 along the circumferential direction of the valve body 1, thereby facilitating the alignment between the opening of the second channel 221 and the third flow channel opening 15, facilitating the communication between the opening of the second channel 221 and the third flow channel opening 15, and ensuring the communication area between the second channel 221 and the flow channel cavity 12 and the smoothness of the liquid flow.

[0077] In some embodiments of the present application, as shown in FIG15 , multiple first gaskets 3 are integrally formed, thereby facilitating assembly of the first gaskets 3 and improving assembly efficiency. For example, in the example shown in FIG15 , multiple first gaskets 3 are sequentially connected to form an open ring. Of course, the present application is not limited to this. Multiple first gaskets 3 can also be directly connected to form a ring and sleeved outside the second core segment 22.

[0078] Of course, the present application is not limited thereto, and the plurality of first sealing gaskets 3 may also be a plurality of independent separate parts, thereby simplifying the structure and processing technology of the first sealing gaskets 3 and improving production efficiency.

[0079] In some embodiments of the present application, as shown in Figures 4, 6, and 14, a second sealing gasket 4 is disposed between the axial end surface of the valve core 2 facing the first flow openings 13 and the inner wall surface of one axial end of the mounting cavity 11. The second sealing gasket 4 is provided with a relief opening 44 that is opposite to and communicates with the plurality of first flow openings 13. This allows for sealing between the first channel 211 and the first flow openings 13 when they are in communication, thereby improving the reliability of the multi-way valve 100.

[0080] In the example shown in FIG2 , a plurality of first flow passage openings 13 are spaced apart along the circumferential direction of the valve body 1 . In conjunction with FIG14 , the second sealing gasket 4 includes an inner ring portion 41, an outer ring portion 42, and a connecting portion 43. The outer ring portion 42 is sleeved outside the inner ring portion 41 and spaced apart from the inner ring portion 41. The connecting portions 43 are spaced apart along the circumferential direction of the inner ring portion 41. One end of the connecting portion 43 is connected to the inner ring portion 41, and the other end of the connecting portion 43 is connected to the outer ring portion 42. The inner ring portion 41 is located radially inward of the plurality of first flow passage openings 13 , the outer ring portion 42 is located radially outward of the plurality of first flow passage openings 13 , the connecting portion 43 is located between two adjacent first flow passage openings 13 , and the avoidance opening 44 is located between two adjacent connecting portions 43 .

[0081] In some embodiments of the present application, the valve core 2 is a single piece. It is understood that the first core segment 21 and the second core segment 22 are a single piece. When the first core segment 21 rotates, the second core segment 22 rotates synchronously. The liquid in the first core segment 21 adjusts its flow direction through the first channel 211 and the liquid in the second core segment 22 adjusts its flow direction through the second channel 221 simultaneously. This simplifies the assembly process between the first and second core segments 21, 22, and improves assembly efficiency.

[0082] Of course, the present application is not limited to this. As shown in Figures 6, 7 and 10, the first core segment 21 and the second core segment 22 are separate parts. The first core segment 21 is provided with a first protrusion 212 on the axial end face facing the second core segment 22, and the second core segment 22 is provided with a second protrusion 222 on the axial end face facing the first core segment 21. The first protrusion 212 and the second protrusion 222 are arranged in the circumferential direction of the valve core 2 and the end face of the first protrusion 212 at one end along the circumferential direction of the valve core 2 is suitable for abutting with the end face of the second protrusion 222 at one end along the circumferential direction of the valve core 2.

[0083] The first core segment 21 and the second core segment 22 can rotate independently within a certain range. The flow direction of the liquid in the first core segment 21 is adjusted through the first channel 211, and the flow direction of the liquid in the second core segment 22 is adjusted through the second channel 221. This can increase the multidirectionality of the liquid flow direction of the multi-way valve 100 and meet more needs.

[0084] For example, during adjustment, the first core segment 21 can be rotated forward until the first protrusion 212 and the second protrusion 222 stop, and the first core segment 21 drives the second core segment 22 to continue rotating forward until the second core segment 22 is adjusted to the desired position. Then, the first core segment 21 is rotated backward, the first protrusion 212 and the second protrusion 222 separate, and the first core segment 21 can be rotated alone until the first core segment 21 is adjusted to the desired position. Of course, the second core segment 22 can also drive the first core segment 21 to rotate, and this is not limited here.

[0085] Of course, the present application is not limited thereto, and other transmission components may be provided between the first core segment 21 and the second core segment 22, so that the first core segment 21 can rotate alone and also drive the second core segment 22 to rotate.

[0086] Furthermore, as shown in Figures 7 and 10, a first annular boss 213 is provided on the axial end surface of the first core segment 21 facing the second core segment 22, and a second annular boss 223 is provided on the axial end surface of the second core segment 22 facing the first core segment 21. The first annular boss 213 is disposed around the second annular boss 223, or the second annular boss 223 is disposed around the first annular boss 213. The first protrusion 212 and the second protrusion 222 are located radially outward of the first annular boss 213 and the second annular boss 223. The first annular boss 213 and the second annular boss 223 can support the first and second core segments 21 and 22, preventing the first and second core segments 21 and 22 from tilting due to the first and second protrusions 212 and 222, respectively. Furthermore, the first and second annular bosses 213 and 223 can guide the relative rotation of the first and second core segments 21 and 22, thereby ensuring the reliability of the relative fixation between the first and second core segments 21 and 22.

[0087] For example, in the examples shown in Figures 7 and 10, the first annular boss 213 is located radially outside the second annular boss 223 and is spaced apart, the first protrusion 212 and the second protrusion 222 are both located radially outside the first annular boss 213, the first annular boss 213 and the first protrusion 212 are connected, and the second protrusion 222 and the second annular boss 223 are spaced apart.

[0088] In some embodiments of the present application, as shown in Figures 1, 4, and 6, a transmission shaft 224 is provided on the axial end surface of the valve core 2 facing the first flow channel opening 13 or on the axial end surface of the valve core 2 facing away from the first flow channel opening 13, and the transmission shaft 224 extends out of the valve body 1. It is understandable that when the transmission shaft 224 is provided on the axial end surface of the valve core 2 facing the first flow channel opening 13, the transmission shaft 224 is connected to the first core segment 21, and the transmission shaft 224 and the first core segment 21 can be an integral part; when the transmission shaft 224 is provided on the axial end surface of the valve core 2 facing away from the first flow channel opening 13, the transmission shaft 224 is connected to the second core segment 22, and the transmission shaft 224 and the second core segment 22 can be an integral part.

[0089] Therefore, the transmission shaft 224 can be driven to rotate by an external driving mechanism, thereby driving the valve core 2 to rotate, thereby adjusting the flow direction of the liquid.

[0090] For example, in the examples shown in Figures 4, 6 and 11, a transmission shaft 224 is provided on the end face of the second core segment 22 facing away from the first core segment 21, a rotating shaft 214 is provided on the end face of the first core segment 21 facing away from the second core segment 22, and a rotating hole that cooperates with the rotating shaft 214 is provided on the valve body 1. When the first core segment 21 and the second core segment 22 are separate parts, the second core segment 22 can drive the first core segment 21 to rotate.

[0091] In some embodiments of the present application, as shown in Figures 16, 24, 25, and 28, a second rotating shaft 225 is provided on the side of the second core segment 22 facing away from the first core segment 21. The second rotating shaft 225 extends out of the mounting cavity 11. A first rotating shaft 215 is provided on the side of the first core segment 21 facing the second core segment 22. The first rotating shaft 215 is rotatably disposed within the second core segment 22 and the second rotating shaft 225. The axes of the first rotating shaft 215 and the second rotating shaft 225 may coincide. The first core segment 21 and the second core segment 22 each have independent rotating shafts. The first rotating shaft 215 and the second rotating shaft 225 can be driven to rotate by a single actuator that is simultaneously connected to the first rotating shaft 215 and the second rotating shaft 225. The first rotating shaft 215 and the second rotating shaft 225 can also be driven to rotate by two independent actuators that are respectively connected to the first rotating shaft 215 and the second rotating shaft 225 to drive the first core segment 21 and the second core segment 22 to rotate.

[0092] In the present application, the first core segment 21 and the second core segment 22 are actively driven by the actuator through the first rotating shaft 215 and the second rotating shaft 225 respectively, which can improve the control accuracy of the rotation angle of the first core segment 21 and the second core segment 22. At the same time, the first core segment 21 and the second core segment 22 are integrated in an installation cavity 11, and the first rotating shaft 215 and the second rotating shaft 225 both extend toward an axial direction of the valve body 1, which can improve space utilization and reduce costs.

[0093] A second rotating shaft 225 is provided on the side of the second core segment 22 facing away from the first core segment 21, the second rotating shaft 225 extending out of the mounting cavity 11, and a first rotating shaft 215 is provided on the side of the first core segment 21 facing the second core segment 22. The first rotating shaft 215 is rotatably disposed within the second core segment 22 and the second rotating shaft 225. The first rotating shaft 215 and the second rotating shaft 225 can be driven to rotate by an actuator, thereby respectively driving the first core segment 21 and the second core segment 22 to rotate. The first core segment 21 and the second core segment 22 are both actively driven, which can improve the control accuracy of the rotation angle of the first core segment 21 and the second core segment 22. At the same time, the first core segment 21 and the second core segment 22 are integrated into a single mounting cavity 11, and the first rotating shaft 215 and the second rotating shaft 225 both extend toward an axial direction of the valve body 1, which can improve space utilization and reduce costs.

[0094] In some embodiments of the present application, as shown in Figures 1, 17, 20, and 21, the end of the first rotating shaft 215 away from the first core segment 21 passes through the second rotating shaft 225. This facilitates the connection between the actuator and the first rotating shaft 215, thereby facilitating the rotation of the first rotating shaft 215 and the first core segment 21.

[0095] Furthermore, a sealing ring is provided between the outer circumferential wall of the first rotating shaft 215 and the inner circumferential wall of the second rotating shaft 225. This seals the outer circumferential wall of the first rotating shaft 215 and the inner circumferential wall of the second rotating shaft 225, preventing liquid in the first channel 211 or the second channel 221 from flowing into the mounting cavity 11 and leaking through the gap between the outer circumferential wall of the first rotating shaft 215 and the inner circumferential wall of the second rotating shaft 225, thereby ensuring the operational reliability of the multi-way valve 100. Furthermore, a plurality of sealing rings are provided, spaced apart along the axial direction of the first rotating shaft 215.

[0096] In some embodiments of the present application, a sealing groove is provided on the outer peripheral wall of the first rotating shaft 215 . The sealing groove is an annular groove extending along the circumferential direction of the first rotating shaft 215 , and a sealing ring is disposed in the sealing groove.

[0097] In some embodiments of the present application, as shown in Figures 16, 17, 20, 21, and 24, the multi-way valve 100 further includes a third rotating shaft 5. The third rotating shaft 5 is located outside the mounting cavity 11 and is rotatably disposed on the axial end face of the valve body 1 away from the first core segment 21. The third rotating shaft 5 is transmission-connected to the second rotating shaft 225, and the axis of the third rotating shaft 5 is spaced apart from the axis of the first rotating shaft 215. The actuator can be connected to the third rotating shaft 5 and, through transmission between the third rotating shaft 5 and the second rotating shaft 225, drive the second rotating shaft 225, thereby avoiding the problem of the actuator having difficulty driving the first rotating shaft 215 and the second rotating shaft 225 due to the coincidence of the axes of the first rotating shaft 215 and the second rotating shaft 225.

[0098] In some embodiments of the present application, as shown in Figures 16, 17, 20, 21, and 24, the axis of the third rotating shaft 5 is parallel to the axis of the second rotating shaft 225. A first gear 226 is fixedly disposed on the outer surface of the second rotating shaft 225, and a second gear 51 is fixedly disposed on the outer surface of the third rotating shaft 5. The first gear 226 and the second gear 51 are meshed. The gear transmission has high precision and stability, which can improve the transmission accuracy between the third rotating shaft 5 and the second rotating shaft 225, thereby improving the control accuracy of the rotation angle of the second core segment 22.

[0099] Specifically, the transmission ratio between the first gear 226 and the second gear 51 can be 1:1. This ensures that the first gear 226 and the second gear 51 rotate at the same speed, facilitating control of the second rotating shaft 225 via the third rotating shaft 5. The first gear 226 and the second gear 51 can have the same number of teeth, thereby ensuring a 1:1 transmission ratio between the first gear 226 and the second gear 51. Of course, the present application is not limited thereto, and the transmission ratio between the first gear 226 and the second gear 51 can be greater than or less than 1.

[0100] Of course, the present application is not limited thereto, and the transmission connection between the third rotating shaft 5 and the second rotating shaft 225 may also be a worm gear structure transmission connection, a chain or a transmission belt transmission connection.

[0101] In some embodiments of the present application, as shown in Figure 21, the first gear 226 and the second rotating shaft 225 are separate parts. When the second core segment 22 and the second rotating shaft 225 are assembled, the second core segment 22 and the second rotating shaft 225 can be assembled into the installation cavity 11, and then the second rotating shaft 225 can be passed through the installation cavity 11, and then the first gear 226 can be sleeved and fixed on the second rotating shaft 225 to facilitate the installation of the second core segment 22 into the installation cavity 11.

[0102] Among them, the second rotating shaft 225 has a mounting section, the outer contour of the cross section of the mounting section is non-circular, the first gear 226 can be installed on the mounting section, and the cross section of the inner circumferential wall of the first gear 226 is non-circular to match the mounting section, so that the rotation of the first gear 226 is transmitted to the second rotating shaft 225, realizing the coaxial rotation of the first gear 226 and the second rotating shaft 225.

[0103] In some embodiments of the present application, as shown in FIG21 , the second gear 51 and the third rotating shaft 5 are integrated into one piece, thereby simplifying the assembly process between the second gear 51 and the third rotating shaft 5 and improving production efficiency.

[0104] In some embodiments of the present application, as shown in Figure 21, a mounting groove 171 is provided on the axial outer end face of the valve body 1, and one end of the third rotating shaft 5 is rotatably provided in the mounting groove 171, which is convenient for fixing the third rotating shaft 5 and can provide better support for the third rotating shaft 5, thereby facilitating the rotation of the third rotating shaft 5.

[0105] In some embodiments of the present application, as shown in Figures 19-21, the first rotating shaft 215 and the first core segment 21 are integrally formed, thereby eliminating the need for assembly steps between the first rotating shaft 215 and the first core segment 21, thereby improving production efficiency. The second rotating shaft 225 and the second core segment 22 are integrally formed, thereby eliminating the need for assembly steps between the second rotating shaft 225 and the second core segment 22, thereby improving production efficiency.

[0106] In some embodiments of the present application, as shown in Figures 18, 20, 22, 23, 26, 27, 29 and 30, the first flow channel opening 13 and the second flow channel opening 14 are provided on the axial end surface of the valve body 1 which is away from the first rotation axis 215.

[0107] In some embodiments of the present application, as shown in Figures 1 and 4 , the valve body 1 includes a valve body 16 and a valve cover 17. The valve body 16 is a single piece, and the valve cover 17 is connected to the valve body 16 and together defines a mounting cavity 11. The flow channel cavity 12 is provided within the valve body 16, and the first flow channel opening 13 and the second flow channel opening 14 are provided on the end surface of the valve body 16 facing away from the valve cover 17. This not only facilitates the assembly of the valve core 2, but also greatly simplifies the assembly process of the multi-way valve 100.

[0108] Furthermore, a sealing gasket may be provided between the valve body 16 and the valve cover 17 to ensure the sealing of the valve body 1 and prevent the valve body 1 from leaking.

[0109] In some embodiments of the present application, as shown in FIG2 , multiple first flow openings 13 are spaced apart along the circumference of the valve body 1 . This allows for a more compact and reasonable arrangement of the multiple first flow openings 13 , relatively increasing the number of first channels 211 , achieving the multi-way requirements of the multi-way valve 100 and meeting higher demands. Multiple second flow openings 14 are located radially outward of the first flow openings 13 and spaced apart along the circumference of the valve body 1 .

[0110] In some examples of the present application, as shown in Figures 25 to 30, multiple third flow channel openings 15 are provided on the peripheral wall of the installation cavity 11 and are arranged at intervals along the circumferential direction of the installation cavity 11. The openings at both ends of each second channel 221 are located on the outer peripheral wall of the second core segment 22, and the two ends of the second channel 221 are respectively suitable for direct communication with the two third flow channel openings 15, so as to facilitate the communication between the second channel 221 and the third flow channel openings 15; as shown in Figure 28, the opening of the first channel 211 is located on the axial end face of the first core segment 21 facing away from the second core segment 22, so as to facilitate the communication between the first channel 211 and the first flow channel opening 13.

[0111] The following describes a multi-way valve 100 according to three specific embodiments of the present application. It is worth noting that the following description is merely exemplary and is only used to explain the present application, and is not to be construed as a limitation on the present application.

[0112] Example 1

[0113] As shown in FIG. 16 to FIG. 30 , the multi-way valve 100 according to an embodiment of the present application includes a valve body 1 and a valve core 2 .

[0114] As shown in Figures 16, 20, and 23, the valve body 1 has a mounting cavity 11 with a circular cross-section. As shown in Figures 18 and 22, the valve body 1 is provided with a plurality of first flow openings 13 and a plurality of second flow openings 14. Specifically, the first flow openings 13 and the second flow openings 14 are provided on an end surface at one axial end of the valve body 1.

[0115] As shown in Figures 20 and 24, the valve core 2 is rotatably disposed in the mounting cavity 11. Along the axial direction of the valve core 2, the valve core 2 includes a first core segment 21 and a second core segment 22. As shown in Figures 26 and 27, the first core segment 21 is provided with a plurality of first channels 211 that are not connected to each other, and each first channel 211 is connected to at least two first flow channel openings 13. As shown in Figures 29 and 30, the second core segment 22 is provided with a plurality of second channels 221 that are not connected to each other, and each second channel 221 is connected to at least two second flow channel openings 14.

[0116] As shown in Figures 16, 24, 25 and 28, a second rotating shaft 225 is provided on the side of the second core segment 22 facing away from the first core segment 21, and the second rotating shaft 225 extends out of the mounting cavity 11. A first rotating shaft 215 is provided on the side of the first core segment 21 facing the second core segment 22. The first rotating shaft 215 is rotatably passed through the second core segment 22 and the second rotating shaft 225, and the end of the first rotating shaft 215 away from the first core segment 21 passes through the second rotating shaft 225, and the axis of the first rotating shaft 215 and the axis of the second rotating shaft 225 can coincide. The first core segment 21 and the second core segment 22 both have independent rotating shafts. The first rotating shaft 215 and the second rotating shaft 225 can be driven to rotate by an actuator, and the actuator is simultaneously connected to the first rotating shaft 215 and the second rotating shaft 225; the first rotating shaft 215 and the second rotating shaft 225 can be driven to rotate by two independent actuators, and the two actuators are respectively connected to the first rotating shaft 215 and the second rotating shaft 225 to respectively drive the first core segment 21 and the second core segment 22 to rotate.

[0117] In the present application, the first core segment 21 and the second core segment 22 are actively driven by the actuator through the first rotating shaft 215 and the second rotating shaft 225 respectively, which can improve the control accuracy of the rotation angle of the first core segment 21 and the second core segment 22. At the same time, the first core segment 21 and the second core segment 22 are integrated in an installation cavity 11, and the first rotating shaft 215 and the second rotating shaft 225 both extend toward an axial direction of the valve body 1, which can improve space utilization and reduce costs.

[0118] In addition, as shown in Figures 16, 17, 20, 21 and 24, the multi-way valve 100 also includes a third rotating shaft 5, which is located outside the mounting cavity 11 and is rotatably provided on the axial end face of the valve body 1 away from the first core segment 21. The third rotating shaft 5 is transmission-connected to the second rotating shaft 225 and the axis of the third rotating shaft 5 is spaced apart from the axis of the first rotating shaft 215.

[0119] Specifically, the axis of the third rotating shaft 5 is parallel to the axis of the second rotating shaft 225. A first gear 226 is fixedly disposed on the outer surface of the second rotating shaft 225, and a second gear 51 is fixedly disposed on the outer surface of the third rotating shaft 5. The first gear 226 and the second gear 51 are meshed. The transmission ratio of the first gear 226 and the second gear 51 can be 1:1. The first gear 226 and the second rotating shaft 225 are separate components, while the second gear 51 and the third rotating shaft 5 are integrated.

[0120] Furthermore, as shown in Figures 18, 20, 22, 23, 26, 27, 29, and 30, the valve body 1 further comprises a plurality of flow passages 12. These are located radially outward from the mounting cavity 11 and spaced apart along the circumference of the mounting cavity 11. The flow passages 12 may extend circumferentially along the valve body 1. A first flow passage opening 13 and a second flow passage opening 14 are provided on the axial end surface of the valve body 1 that faces away from the first rotation axis 215. The plurality of second flow passage openings 14 are respectively connected to the plurality of flow passages 12. A plurality of third flow passage openings 15 are provided on the circumferential wall of the mounting cavity 11 and spaced apart along the circumference of the mounting cavity 11. The openings at both ends of each second channel 221 are located on the outer circumferential wall of the second core segment 22. Each second channel 221 is connected to at least two third flow passage openings 15.

[0121] As shown in FIG. 28 , the opening of the first channel 211 is located on the axial end face of the first core segment 21 facing away from the second core segment 22 , facilitating the communication between the first channel 211 and the first flow channel opening 13 .

[0122] Furthermore, as shown in Figure 23, a reinforcing rib 151 is provided in the third flow channel opening 15, and the two ends of the reinforcing rib 151 are respectively connected to the two inner walls of the third flow channel opening 15 opposite to each other in the axial direction of the valve body 1, thereby enhancing the structural strength of the valve body 1 at the third flow channel opening 15.

[0123] In this embodiment, the second core segment 22 adopts the structure of a column valve. When the liquid in the flow channel cavity 12 flows to the second channel 221, it flows directly into the second channel 221 along the radial direction of the valve body 1, which has a shorter stroke, fewer bends, and lower flow resistance. The first core segment 21 adopts the structure of a disc valve, which improves space utilization, facilitates the setting of multiple channels, and is relatively low in cost. In this application, by making the first core segment 21 adopt the structure of a disc valve and the second core segment 22 adopt the structure of a column valve, not only can space utilization be improved, which is conducive to the setting of multiple channels, but also flow resistance can be reduced, and complex through-path requirements can be met, and the volume is relatively small.

[0124] Example 2

[0125] As shown in Figures 31 and 32, the structure of this embodiment is substantially the same as that of the first embodiment, with identical components designated by the same reference numerals. The only difference is that this embodiment lacks the third rotating shaft 5, the second gear 51 sleeved on the third rotating shaft 5, and the first gear 226 sleeved on the second rotating shaft 225. The remaining structures are identical. The actuator may be directly connected to the first rotating shaft 215 and the second rotating shaft 225, or connected via other structures.

[0126] Example 3

[0127] As shown in Figures 1 to 15, the structure of this embodiment is roughly the same as that of embodiment 1, wherein the same components are marked with the same figures, and the only difference is that the first core segment 21 and the second core segment 22 are split parts, and the first core segment 21 is provided with a first protrusion 212 on the axial end face facing the second core segment 22, and the second core segment 22 is provided with a second protrusion 222 on the axial end face facing the first core segment 21. The first protrusion 212 and the second protrusion 222 are arranged in the circumferential direction of the valve core 2 and the end face of the first protrusion 212 at one end along the circumferential direction of the valve core 2 is suitable for abutting with the end face of the second protrusion 222 at one end along the circumferential direction of the valve core 2.

[0128] The first core segment 21 and the second core segment 22 can rotate independently within a certain range. The flow direction of the liquid in the first core segment 21 is adjusted through the first channel 211, and the flow direction of the liquid in the second core segment 22 is adjusted through the second channel 221. This can increase the multidirectionality of the liquid flow direction of the multi-way valve 100 and meet more needs.

[0129] For example, during adjustment, the first core segment 21 can be rotated forward until the first protrusion 212 and the second protrusion 222 stop, and the first core segment 21 drives the second core segment 22 to continue rotating forward until the second core segment 22 is adjusted to the desired position. Then, the first core segment 21 is rotated backward, the first protrusion 212 and the second protrusion 222 separate, and the first core segment 21 can be rotated alone until the first core segment 21 is adjusted to the desired position. Of course, the second core segment 22 can also drive the first core segment 21 to rotate, and this is not limited here.

[0130] Furthermore, as shown in Figures 7 and 10, a first annular boss 213 is provided on the axial end surface of the first core segment 21 facing the second core segment 22, and a second annular boss 223 is provided on the axial end surface of the second core segment 22 facing the first core segment 21. The first annular boss 213 is disposed around the second annular boss 223, or the second annular boss 223 is disposed around the first annular boss 213. The first protrusion 212 and the second protrusion 222 are located radially outward of the first annular boss 213 and the second annular boss 223. The first annular boss 213 and the second annular boss 223 can support the first and second core segments 21 and 22, preventing the first and second core segments 21 and 22 from tilting due to the first and second protrusions 212 and 222, respectively. Furthermore, the first and second annular bosses 213 and 223 can guide the relative rotation of the first and second core segments 21 and 22, thereby ensuring the reliability of the relative fixation between the first and second core segments 21 and 22.

[0131] As shown in Figures 1, 4, and 6, a transmission shaft 224 is provided on the axial end surface of the valve core 2 facing the first flow channel opening 13 or on the axial end surface of the valve core 2 facing away from the first flow channel opening 13, and the transmission shaft 224 extends out of the valve body 1. It will be understood that when the transmission shaft 224 is provided on the axial end surface of the valve core 2 facing the first flow channel opening 13, the transmission shaft 224 is connected to the first core segment 21, and the transmission shaft 224 and the first core segment 21 can be an integral part. When the transmission shaft 224 is provided on the axial end surface of the valve core 2 facing away from the first flow channel opening 13, the transmission shaft 224 is connected to the second core segment 22, and the transmission shaft 224 and the second core segment 22 can be an integral part.

[0132] Therefore, the transmission shaft 224 can be driven to rotate by an external driving mechanism, thereby driving the valve core 2 to rotate, thereby adjusting the flow direction of the liquid.
