[0046] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0047] As shown in Figures 1 to 13, an embodiment of the present application provides a multi-way valve, including a main body 10 and a valve core 20, the main body 10 has a valve cavity and a plurality of flow ports; the valve core 20 has a plurality of sector areas distributed along the circumferential direction, and the valve core 20 is rotatably arranged in the valve cavity to realize the conversion of the multi-way valve between the first working condition, the second working condition, the third working condition, the fourth working condition, the fifth working condition, and the sixth working condition through different sector areas corresponding to the plurality of flow ports.
[0048] In this embodiment, the correspondence between different sector areas and multiple flow ports and the conversion of different working conditions of the multi-way valve are achieved through the rotation of the valve core 20. Multiple flow paths can be controlled through one valve core, which is easy to use and simple to control.
[0049] Specifically, the valve core 20 has multiple circumferential regions distributed sequentially along the axial direction of the valve core 20. The multiple circumferential regions and the multiple sector-shaped regions form multiple flow channels. This arrangement facilitates achieving different operating conditions of the multi-way valve by aligning the multiple sector-shaped regions with the multiple flow ports.
[0050] Furthermore, in the axial direction of the valve core 20, the lengths of the first circumferential zone 207, the second circumferential zone 208, the third circumferential zone 209, the fourth circumferential zone 210, and the fifth circumferential zone 211 are equal; in the circumferential direction of the valve core 20, the curvatures of the first sector 201, the second sector 202, the third sector 203, the fourth sector 204, the fifth sector 205, and the sixth sector 206 are equal. In this embodiment, by limiting the lengths of the multiple circumferential zones and the curvatures of the multiple sector zones, it is convenient to ensure that the flow areas corresponding to the two flow ports at both ends of any flow channel are the same, avoiding the situation where the flow areas corresponding to the two flow ports at both ends of any flow channel are different, resulting in unequal inflow and outflow of the flow channel, thereby ensuring the reliability and stability of the fluid flowing through the flow channel of the multi-way valve. At the same time, by limiting the curvatures of the multiple sector zones to be equal, it is ensured that the angle of rotation of the valve core 20 corresponding to each sector is the same, ensuring the reliability of the rotation of the valve core 20.
[0051] As shown in Figures 2, 5 and 6, any sector area includes two sub-sectors distributed along the circumference of the valve core 20, and the curvature of the two sub-sectors is the same. Any sub-sector and any circumferential area form a sub-cavity, and all sub-cavities are divided into a first part and a second part. The sub-cavities in the first part are independently arranged, and any one of the sub-cavities in the second part is connected to another sub-cavity in the second part located in the same sector area to form a flow channel.
[0052] This arrangement divides the valve core 20 into 12 sub-sectors in the circumferential direction. Combined with the five circumferential zones divided by the valve core 20 in the axial direction, a total of 60 sub-cavities are formed. Some of the 60 sub-cavities are isolated, that is, they are not connected to any other sub-cavities. The remaining sub-cavities are connected in pairs to form multiple flow channels, so that according to the rotation of the valve core 20 in the valve cavity, different flow channel openings correspond to multiple flow ports, thereby realizing the conversion of multiple working conditions of the multi-way valve. Specifically, in this embodiment, the formation of the flow channel is limited, that is, any flow channel is completely formed in the corresponding sector area, so that when multiple flow ports correspond to two different sector areas at the same time, only the flow channels located in the same sector area and with both ends corresponding to different flow ports will be connected, so as to achieve the limitation of the working conditions.
[0053] In this embodiment, the working conditions of the multi-way valve also include the seventh working condition, the eighth working condition, the ninth working condition, the tenth working condition, the eleventh working condition and the twelfth working condition. The flow states of the above working conditions are different from the first to sixth working conditions, further improving the applicability of the multi-way valve.
[0054] As shown in Figures 4 to 6, in the first operating condition, the rotation angle of the valve core 20 is set to 0°, and n is set to a positive integer with 0<n<12. When the valve core 20 rotates n×30°, where n is an even number, the multi-way valve switches to any one of the second, third, fourth, fifth, and sixth operating conditions. When the valve core 20 rotates 360°, the valve core 20 returns to the first operating condition. When the valve core 20 rotates n×30°, where n is an odd number, the multi-way valve switches to any one of the seventh, eighth, ninth, tenth, eleventh, and twelfth operating conditions. This arrangement facilitates precise adjustment of the multi-way valve's multiple operating conditions, facilitates the processing of the valve core 20, and ensures the reliability and stability of the multi-way valve's flow.
[0055] In this embodiment, the multiple flow ports include a first flow port 001, a second flow port 002, a third flow port 003, a fourth flow port 004, a fifth flow port 005, a sixth flow port 006, a seventh flow port 007, an eighth flow port 008, a ninth flow port 009 and a tenth flow port 010. The multiple flow ports are divided into two rows along the width direction of the valve body 11, one row of which is the first flow port 001, the ninth flow port 009, the tenth flow port 010, the second flow port 002 and the seventh flow port 007 in sequence along the length direction of the valve body 11, and the other row is the sixth flow port 006, the fifth flow port 005, the third flow port 003, the eighth flow port 008 and the fourth flow port 004 in sequence along the length direction of the valve body 11. The multiple flow ports in the two rows correspond to each other one by one, and the first flow port 001 and the sixth flow port 006 are spaced apart along the width direction of the valve body 11.
[0056] It is understandable that the number and distribution of the flow ports, sector areas, and circumferential areas can be adjusted according to actual conditions, and correspondingly, the working conditions will also change accordingly. Examples are not given here one by one.
[0057] Furthermore, the plurality of flow channels include a first flow channel 221 formed by the first sector area 201, the first circumferential area 207, and the second circumferential area 208; a first second flow channel 222 formed by the first sector area 201, the first circumferential area 207, and the fifth circumferential area 211; a first third flow channel 223 formed by the first sector area 201, the second circumferential area 208, and the third circumferential area 209; a first fourth flow channel 224 formed by the first sector area 201, the third circumferential area 209, and the fourth circumferential area 210; and a first fifth flow channel 225 formed by the first sector area 201, the fourth circumferential area 210, and the fifth circumferential area 211. ; A second first flow channel 231 formed by the second sector area 202, the first circumferential area 207, and the second circumferential area 208; a second second flow channel 232 formed by the second sector area 202, the second circumferential area 208, and the third circumferential area 209; a second third flow channel 233 formed by the second sector area 202, the third circumferential area 209, and the fourth circumferential area 210; a second fourth flow channel 234 formed by the second sector area 202, the first circumferential area 207, and the fourth circumferential area 210; a third first flow channel 241 formed by the third sector area 203 and the first circumferential area 207; a third second flow channel 242 formed by the third sector area 203 and the second circumferential area 208, the third circumferential area 210; The third second flow channel 242 formed by the third circumferential zone 209; the third third flow channel 243 formed by the third sector 203 and the fourth circumferential zone 210 and the fifth circumferential zone 211; the fourth first flow channel 251 formed by the fourth sector 204 and the first circumferential zone 207; the fourth second flow channel 252 formed by the fourth sector 204 and the second circumferential zone 208 and the fourth circumferential zone 210; the fourth third flow channel 253 formed by the fourth sector 204 and the third circumferential zone 209 and the fourth circumferential zone 210; the fifth first flow channel 261 formed by the fifth sector 205 and the first circumferential zone 207; the fifth sector 205 and The fifth-second flow channel 262 is formed by the third circumferential zone 209; the fifth-third flow channel 263 is formed by the fifth sector-shaped zone 205 and the second circumferential zone 208 and the fifth circumferential zone 211; the fifth-fourth flow channel 264 is formed by the fifth sector-shaped zone 205 and the fourth circumferential zone 210 and the fifth circumferential zone 211; the sixth-first flow channel 271 is formed by the sixth sector-shaped zone 206 and the first circumferential zone 207; the sixth-second flow channel 272 is formed by the sixth sector-shaped zone 206 and the second circumferential zone 208 and the fifth circumferential zone 211; the sixth-third flow channel 273 is formed by the sixth sector-shaped zone 206 and the third circumferential zone 209 and the fourth circumferential zone 210.
[0058] As shown in Figures 1 to 11, Figures 7 to 11 are cross-sectional views of the multi-way valve in the first working condition, and the rotation angle of the valve core 20 at this time is set to an initial angle of 0°. When the multi-way valve is in the first working condition: the first sector area 201 is opposite to multiple flow ports, and the ten flow ports form five groups of flow channels connected in pairs. The first flow port 001 and the fourth flow port 004 are connected through the first-second flow channel 222, the second flow port 002 and the seventh flow port 007 are connected through the first-fifth flow channel 225, the third flow port 003 and the eighth flow port 008 are connected through the first-fourth flow channel 224, the fifth flow port 005 and the sixth flow port 006 are connected through the first-first flow channel 221, and the ninth flow port 009 and the tenth flow port 010 are connected through the first-third flow channel 223.
[0059] As shown in Figures 4 to 6, the direction from right to left in Figure 4 is the clockwise rotation direction of the valve core 20, n=1, that is, after the valve core 20 rotates 30° clockwise, the multi-way valve switches to the seventh working condition. When the multi-way valve is in the seventh working condition: the first sector 201 and the second sector 202 each have a sub-sector corresponding to multiple flow ports, the sub-sector of the first sector 201 corresponds to a row of flow ports where the seventh flow port 007 is located, and the sub-sector of the second sector 202 corresponds to a row of flow ports where the fourth flow port 004 is located. Combined with the above-mentioned limitation on the formation of the flow channel (that is, any flow channel is completely formed in the corresponding sector, so that when multiple flow ports correspond to two different sector areas at the same time, only the flow channels located in the same sector area and with both ends corresponding to different flow ports will be connected), the first The flow port 001 and the ninth flow port 009 are connected through the first flow channel 221 located in the first sector area 201, the second flow port 002 and the tenth flow port 010 are connected through the first four flow channels 224 located in the first sector area 201, the third flow port 003 and the eighth flow port 008 are connected through the second four flow channels 234 located in the second sector area 202, and the fifth flow port 005 and the sixth flow port 006 are connected through the second one flow channel 231 located in the second sector area 202; the sub-cavity corresponding to the fourth flow port 004 is an independent cavity, and this flow port is not connected with other flow ports; the seventh flow port 007 corresponds to one end of the first two flow channels 222, but the other end of the first two flow channels 222 does not correspond to other flow ports, so the seventh flow port 007 is also equivalent to an independent cavity.

[0068] As shown in Figures 4 to 6, n=10, that is, after the valve core 20 rotates 300° clockwise, the multi-way valve switches to the sixth working condition.

[0069] As shown in Figures 4 to 6, n=11, that is, after the valve core 20 rotates 330° clockwise, the multi-way valve switches to the twelfth working condition. When the multi-way valve is in the twelfth working condition: the sixth sector 206 and the first sector 201 each have a sub-sector corresponding to multiple flow ports, the sub-sector of the sixth sector 206 corresponds to a row of flow ports where the seventh flow port 007 is located, and the sub-sector of the first sector 201 corresponds to a row of flow ports where the fourth flow port 004 is located.

[0070] As shown in Figures 2 and 3, the valve core 20 includes a sleeve 28, two circular end plates 291, multiple axial partitions 292, and multiple fan-shaped partitions 293. The sleeve 28 includes an outer sleeve 281 and an inner sleeve 282 arranged in the outer sleeve 281. There are multiple internal flow channels 283 between the inner sleeve 282 and the outer sleeve 281, which penetrate the valve core 20 axially along the valve core 20. The multiple internal flow channels 283 correspond one-to-one to the multiple fan-shaped areas. The two circular end plates 291 are arranged in parallel and are fixedly connected to the outer sleeve 281. The two circular end plates 291 and the sleeve 28 are coaxially arranged; wherein, the multiple axial partitions 292 and the multiple fan-shaped partitions 293 are distributed in the area enclosed between the two circular end plates 291 and the outer sleeve 281 to divide the multiple fan-shaped areas and the multiple circumferential areas.
[0071] In this embodiment, the main body of the valve core 20 is formed by a shaft sleeve 28 and circular end plates 291 at both ends. A plurality of axial partitions 292 divide the outer periphery of the outer sleeve 281 of the valve core 20 into multiple sectors, and a plurality of sector-shaped partitions 293 divide the outer periphery of the outer sleeve 281 of the valve core 20 into multiple circumferential sectors. This arrangement facilitates the rapid division and arrangement of the 60 sub-cavities in this embodiment. It also allows for the adjustment of the connection between any two adjacent sub-cavities based on the arrangement of the axial partitions 292 and sector-shaped partitions 293, facilitating the arrangement and formation of flow channels. Furthermore, the inner sleeve 282 has multiple cavities, each corresponding to a plurality of sectors. Each cavity has two openings, and the two openings within the same cavity are used to connect any two non-adjacent sub-cavities within the same sector, facilitating the arrangement and formation of flow channels across circumferential sectors.
[0072] As shown in Figures 7 to 11, the main body 10 includes a valve body 11 and a sealing gasket 12 disposed within the valve body 11. The area surrounded by the valve body 11 and the sealing gasket 12 forms a valve cavity. Multiple flow ports all pass through the bottom wall of the valve body 11 and the sealing gasket 12 and are connected to the valve cavity. In this embodiment, the valve cavity has a receiving groove, the sealing gasket 12 is disposed within the receiving groove and is provided with multiple openings corresponding to the multiple flow ports. The valve body 11 also has multiple through holes. The multiple through holes and the multiple openings are connected one-to-one to form multiple flow ports. The side of the sealing gasket 12 facing the valve cavity axis is flush with the inner wall of the valve cavity. The valve core 20 is rotatably disposed within the valve cavity and is sealed with the sealing gasket 12. The sealing gasket 12 is used to seal the flow channel, thereby preventing leakage in the flow channel under certain working conditions, which may cause the multi-way valve to fail.
[0073] As shown in Figures 3 and 7 to 11, the sealing gasket 12 includes an arc-shaped circulation gasket 121 and an arc-shaped blocking gasket 122 that are connected to each other. The arc-shaped circulation gasket 121 is provided with an arc-shaped blocking gasket 122 on both sides of the circumference of the valve core 20. The arc-shaped circulation gasket 121 covers at least one sector area and corresponds to two rows of flow ports, and the arc-shaped blocking gasket 122 covers at least half of the sector area.
[0074] In this embodiment, multiple flow ports are divided into two rows, and both rows of flow ports pass through the arc-shaped flow pad 121. The curvature of the arc-shaped flow pad 121 corresponds to covering two adjacent sub-sectors. By setting the arc-shaped blocking pad 122, the sealing effect of the sealing pad 12 on the valve core 20 is improved, and it is avoided that when only the arc-shaped flow pad 121 is set, a sub-cavity in half of one sector area corresponds to and is connected with one of the flow ports, but the other sub-cavity in the sector area that is connected with the sub-cavity is located in the other half of the sector area and is not provided with the sealing pad 12, resulting in the fluid leaking into the valve cavity after the fluid enters the sector area from the flow port.
[0075] Preferably, the arc-shaped sealing gasket 122 in this embodiment has a plurality of weight-reducing holes 1221. This arrangement is conducive to reducing the weight of the sealing gasket 12 and at the same time is conducive to miniaturizing the sealing gasket 12 while ensuring the sealing effect of the arc-shaped sealing gasket 122.
[0076] Preferably, the sealing gasket 12 further includes a plurality of sealing ribs 123 distributed on the surface of the sealing gasket 12, which avoids the flow openings and the weight-reducing holes 1221. This arrangement helps improve the sealing effect of the sealing gasket 12 between the valve core 20 and the plurality of flow openings. Optionally, the sealing ribs 123 are elastic ribs, which further improves the applicability of the sealing gasket 12.
[0077] It will be appreciated that in this embodiment, the main body 10 further includes a valve cover 13 and a sealing ring. The valve cover 13 is sealed to the valve body 11 via the sealing ring to block the axial opening of the valve cavity. This arrangement utilizes the sealing ring to achieve a seal between the valve body 11 and the valve cover 13, preventing fluid within the valve body 11 from escaping through the valve cover 13 and improving the sealing performance of the multi-way valve.
[0078] As shown in Figures 2, 8, 12 and 13, the valve core 20 is demolded and has a demolding position. The outer surface of the valve core 20 is movably sealed with the inner wall of the valve cavity, and the outer surface of the valve core 20 has a flash 30 at the demolding position; when the valve core 20 rotates, the maximum radius of the ring formed on the outer surface of the valve core 20 is R1, and the maximum radius of the ring formed on the outer surface of the flash 30 is R2, and R2 is less than R1.
[0079] In this embodiment, by adjusting the demolding position, the maximum radius of the ring formed by the flash 30 during valve core 20 rotation is prevented from being larger than the maximum radius of the ring formed by the outer surface of the valve core 20. This prevents the flash 30 from abrading the inner wall of the valve cavity, thereby ensuring the reliability of the valve core component. Specifically, the valve core 20 in this embodiment is injection molded using the injection mold assembly shown in Figure 13, and injection channels can be formed between the different molds.
[0080] Specifically, the demolding position includes multiple axial demolding positions 212, which extend along the direction of the axial partition 292 and are located on the outer surface of the axial partition 292 on the side away from the axis of the valve core 20. The flash 30 located at the axial demolding position 212 is arranged on the outer surface of the axial partition 292 along the circumference of the valve core 20.
[0081] As shown in FIG12 , the outer surface of the axial partition 292 is partition surface 2921. The flash 30 located at the axial demolding position 212 is disposed on the outer surface of the axial partition 292 (partition surface 2921) along the axial direction of the valve core 20 in one direction and on the outer surface of the axial partition 292 (partition surface 2921) along the circumference of the valve core 20 in the other direction. This arrangement ensures that the flash 30 formed at the axial demolding position 212 does not rotate and wear the inner wall of the valve cavity, while also ensuring the demolding effect of the axial demolding position 212, thereby facilitating the demolding of the valve core 20.
[0082] As shown in Figure 12, the cross-sectional shape of the axial partition 292 is such that the outer surface (partition surface 2921) is a bilaterally symmetrical circular arc, the center of which is the symmetry line passing through the axis of the valve core 20. The flash 30 is distributed along the circumference of the valve core 20 and is located on one side of the symmetry line. In this embodiment, the axial demolding positions 212 on the multiple axial partitions 292 are defined so that the flash 30 is not formed in the center of the partition surface 2921. This further ensures that the strip-shaped flash 30 formed by demolding at the multiple axial demolding positions 212 does not affect the rotation of the valve core 20 within the valve cavity.
[0083] The outer surface of the sector-shaped partition 293, facing away from the axis of the valve core 20, is in active sealing engagement with the inner wall of the valve cavity, and the flash 30 at the axial demolding position 212 clears the outer surface of the sector-shaped partition 293. This arrangement prevents the flash 30 formed on the sector-shaped partition 293 during demolding at the axial demolding position 212 from protruding from the outer surface of the valve core 20, thereby ensuring the reliability of the valve core component.
[0084] Furthermore, the demolding position includes two circumferential demolding positions 213, the valve core 20 includes circular end plates 291 located at both ends, the circumferential demolding position 213 extends along the circumference of the circular end plate 291 and is located on the outer surface of the circular end plate 291 away from the axis of the valve core 20, and the flash 30 located at the circumferential demolding position 213 is arranged on the outer surface of the circular end plate 291 along the axial direction of the valve core 20.
[0085] In this embodiment, the outer surface of the circular end plate 291 serves as the end plate surface. The flash 30 located at the circumferential demolding position 213 is disposed on the outer surface (end plate surface) of the circular end plate 291 in one direction along the circumference of the circular end plate 291 and on the outer surface (end plate surface) of the circular end plate 291 in the other direction along the axis of the valve core 20. This arrangement ensures that the flash 30 formed at the circumferential demolding position 213 does not rotate and abrade the inner wall of the valve cavity, thereby ensuring the demolding effect of the circumferential demolding position 213 and facilitating the demolding of the valve core 20.
[0086] Furthermore, in terms of the cross-sectional shape of the circular end plate 291, the outer surface (end plate surface, which can also be understood as the outer peripheral surface of the circular end plate 291) is a left-right symmetrical arc, the center of the arc is the symmetry line passing through the axis of the valve core 20, and the flash 30 is arranged along the axis of the valve core 20 and is located on one side of the symmetry line. In this embodiment, the circumferential demolding positions 213 on the two circular end plates 291 are limited so that the flash 30 will not be formed in the center position of the end plate surface, further ensuring that the annular flash 30 formed by demolding at multiple circumferential demolding positions 213 will not affect the rotation of the valve core 20 in the valve cavity. It can be understood that the cross-sectional shape of the outer surface (end plate surface) of the circular end plate 291 and the cross-sectional shape of the outer surface (partition surface 2921) of the axial partition 292 are both arcs. Multiple partition surfaces 2921 and multiple end plate surfaces are used to form the outer surface of the valve core 20 that is movably sealed with the inner wall of the valve cavity.
[0087] Preferably, the material of the valve core 20 is plastic, and the valve core 20 is injection molded. This arrangement facilitates the processing and molding of the valve core 20.
[0088] Specifically, the multi-way valve further includes an actuator, which is disposed on the main body 10 and is drivingly connected to the valve core 20. This arrangement facilitates the rotational control of the valve core 20. It is understood that the actuator is a single-motor actuator. Optionally, the multi-way valve further includes a rotating shaft, one end of which is fixedly disposed within the valve core 20 and the other end of which protrudes from the valve core 20 and the valve cover 13. The actuator is drivingly connected to the end of the rotating shaft protruding from the valve core 20.
