The seal 100 provides a seal that prevents leakage of fluids or solid particles from adjacent bonding surfaces, and the seal 100 has a wide range of applications. In embodiments of the present utility model, when the seal 100 is used between a valve spool and a valve housing within the multi-way valve 1000, the seal 100 prevents fluid from flowing between the valve housing and the valve spool, thereby preventing leakage from the multi-way valve 1000.

Be provided with a plurality of holes 11 of dodging on body 1, fluid accessible dodges hole 11 and flows between case and valve casing, can avoid causing the interference to the flow of fluid through setting up dodging hole 11, and sealing member 100 installs between the inner wall of valve casing and the periphery wall of case, can avoid fluid flow to between case and the valve casing, avoids the weeping condition to appear in multi-way valve 1000.

It can be appreciated that the valve core and/or the valve housing are/is provided with a plurality of through holes for flowing medium, the body 1 is provided with a plurality of avoiding holes 11, the plurality of avoiding holes 11 can be arranged in one-to-one correspondence with the plurality of through holes, and the sealing member 100 separates the plurality of through holes from each other, so that the fluid leakage caused by direct communication of the adjacent through holes is avoided, and the reliability and stability of the multi-way valve 1000 can be improved.

The sealing ring 20 in the embodiment of the utility model further comprises a sealing rib assembly 2, the sealing rib assembly 2 comprises a plurality of sealing rings 20, the sealing rings 20 surround the avoidance holes 11, i.e. the plurality of avoidance holes 11 are mutually spaced by the plurality of sealing rings 20. When the sealing member 100 is installed between the inner wall of the valve housing and the outer circumferential wall of the valve core, the sealing effect of the sealing member 100 can be improved by providing the sealing ring 20, and the plurality of through holes on the valve core or the valve housing can be further spaced apart from each other, thereby further improving the reliability and stability of the multi-way valve 1000.

The sealing ring 20 comprises a first side wall 201 extending in a first direction and a second side wall 202 extending in a second direction, the first side wall 201 and the second side wall 202 being connected to each other, the intersection of the first side wall 201 and the second side wall 202 forming a corner 203, the first side wall 201 and the second side wall 202 being connected to form the sealing ring 20. The first and second directions herein may be straight directions, and the first and second sidewalls 201 and 202 extend in the straight directions; the first direction and/or the second direction may also be curved directions, i.e. the extending direction of the first sidewall 201 and/or the second sidewall 202 may also be curved directions, which falls within the scope of the present utility model.

Wherein, the first direction intersects with the second direction and the thickness direction respectively, the sealing rib assembly 2 is connected with the side surface of the thickness direction of the body 1, and the sealing ring 20 can be arranged protruding from the thickness direction of the body 1. It will be appreciated that the seal 100 is elastically deformed by pressure extrusion during operation, thereby enhancing the sealing effect. By providing the sealing rib assembly 2 protruding from the body 1 on the body 1 of the sealing member 100, the sealing effect between the plurality of avoidance holes 11 can be further improved.

Alternatively, the sealing rib assembly 2 may be disposed only on the side surface of the body 1 contacting the outer peripheral wall of the valve core, compared with the direct contact between the body 1 and the valve core, the contact area between the sealing member 100 and the valve core can be reduced by the contact between the sealing rib assembly 2 and the valve core, the friction moment between the valve core and the sealing member 100 is smaller, and the rotation smoothness of the valve core can be improved. And does not disrupt the sealing action of the seal 100, thereby improving the reliability and stability of the multi-way valve 1000. The sealing rib assembly 2 can also play a role in improving the structural strength of the sealing element 100, reduce the occurrence of cracking caused by impact of the sealing element 100 and improve the working stability of the sealing element 100.

Alternatively, the seal rib assembly 2 may be disposed only on the side where the body 1 contacts the inner wall of the valve housing, or alternatively, the seal rib assembly 2 may be disposed on both the side where the body 1 contacts the outer peripheral wall of the valve core and the side where the body 1 contacts the inner wall of the valve housing. The arrangement form of the arrangement position of the sealing rib assembly 2 can be selected according to actual needs, and all the arrangement forms fall within the protection scope of the utility model.

The first side wall 201 and the second side wall 202 of the seal ring 20 are each a strip-shaped member having similar shapes, and when the seal ring is in sealing operation, the first side wall 201 and the second side wall 202 are deformed similarly due to compression, and the surface pressures at the first side wall 201 and the second side wall 202 of the seal ring 20 are similar. And at the corners of the sealing ring 20, i.e. the intersections of the first and second side walls, the surface pressure at the center of the corner is greater due to the influence of the intersecting edges, while the surface pressure at the peripheral locations around the center of the corner is smaller, and the surface pressure at the peripheral locations of the corner is much smaller than the surface pressure at the first and second side walls of the sealing ring. The surface pressure distribution of the sealing ring is uneven, the leakage risk of the position with smaller surface pressure is higher, fluid is easy to leak out from the surrounding positions of the corners, the sealing of the avoidance holes is not facilitated, and the sealing effect of the sealing piece can be reduced.

Thus, in an embodiment of the utility model, at least one corner 203 of the seal ring 20 has a rounded chamfer. By providing the corner 203 of the seal ring 20 with a circular arc chamfer, the surface pressure of the corner 203 around the center position can be raised so that the surface pressure of the corner 203 around the center position is similar to the surface pressure of the first side wall 201 and the second side wall 202 of the seal ring 20. The whole surface of the sealing ring 20 is pressed uniformly, a circle of complete and uniform sealing surface pressing is completed for the avoiding holes 11, and the sealing effect of the sealing piece 100 is improved.

It should be noted that, between the radius R1 of the circular arc chamfer and the length L1 of the first sidewall 201 in the first direction, it is satisfied that: R1/L1 is 0.08 is 0.2 and/or R1/L2 is 0.08 is 0.2 between the radius R1 of the circular arc chamfer and the length L2 of the second side wall 202 in the second direction. The working stability of the sealing member 100 can be affected by too large or too small arc chamfer, and when the arc chamfer is too large, interference can be formed with the avoiding hole 11, so that interference is caused to the flow of the fluid medium, and the functionality of the avoiding hole 11 is affected. On the other hand, when the arc chamfer is too large, the area of the corner 203 is too large, the contact area between the sealing member 100 and the valve core is increased, the valve core needs to resist a large friction moment when rotating relative to the valve housing, and the valve core has a phenomenon of unsmooth rotation, so that the sensitivity of the multi-way valve 1000 for controlling fluid is reduced. When the circular arc chamfer is too small, a large surface pressure cannot be formed at the peripheral position of the corner 203 of the seal ring 20, and the surface pressure is unevenly distributed, which is not beneficial to the sealing effect of the seal member 100. The radius R1 of the circular arc chamfer is set in the range, so that the sealing effect of the sealing element 100 can be effectively improved, and the normal operation of the avoidance hole 11 and the valve core can not be influenced.

Alternatively, the radius R1 of the circular arc chamfer may only satisfy the dimensional requirement with the length L1 of the first sidewall 201 in the first direction, or the radius R1 of the circular arc chamfer may also only satisfy the dimensional requirement with the length L2 of the second sidewall 202 in the second direction, or the radius R1 of the circular arc chamfer may also satisfy the dimensional requirement with the length L2 of the second sidewall 202 in the second direction on the basis of the dimensional requirement with the length L1 of the first sidewall 201 in the first direction.

Alternatively, the ratio of the radius R1 of the circular arc chamfer to the length L1 of the first sidewall 201 in the first direction may be 0.08, 0.09, 0.1, 0.15, 0.2, etc.; alternatively, the ratio of the radius R1 of the circular arc chamfer to the length L2 of the second sidewall 202 in the second direction may be 0.08, 0.1, 0.12, 0.15, 0.16, 0.19, 0.2, etc.

According to the sealing element 100 provided by the embodiment of the utility model, the sealing rib assembly 2 is arranged, and the sealing element 100 assembly forms the sealing ring 20 to surround the avoidance hole 11, so that the sealing effect of the sealing element 100 can be further improved, and the reliability and stability of the multi-way valve 1000 are improved. And through setting up the circular arc chamfer at the corner 203 of sealing ring 20, can make the face pressure of the position around the corner 203 close with the face pressure of the first lateral wall 201 and the second lateral wall 202 of sealing ring 20, the whole each face pressure of sealing ring 20 is even, and sealing effect of sealing member 100 is good. The radius R1 of the circular arc chamfer and the length L1 of the first sidewall 201 along the first direction satisfy: R1/L1 is more than or equal to 0.08 and less than or equal to 0.2, and/or R1 of the circular arc chamfer and the length L2 of the second side wall 202 along the second direction are more than or equal to 0.08 and less than or equal to 0.2, so that the sealing effect of the sealing element 100 can be effectively improved, the normal operation of the avoidance hole 11 and the valve core can not be influenced, and the reliability and the stability of the multi-way valve 1000 with the sealing element 100 are improved.

In some embodiments of the present utility model, referring to fig. 1, any corner 203 of all seal rings 20 is provided with a circular arc chamfer, and each surface of each seal ring 20 is pressed uniformly, so as to improve the sealing effect of the seal 100.

In some embodiments of the utility model, the length L1 of the first side wall 201 of the sealing ring 20 in the first direction is 18mm and the rounded chamfer of the corner 203 of the sealing ring 20 is 2.5mm. The surface pressure at the minimum of this seal ring 20 was 1.1MPa, and the overall average surface pressure of the seal ring 20 was 1MPa. The minimum surface pressure of the sealing ring with the same specification and size, but without the circular arc chamfer at the corner, namely the surface pressure of the surrounding position at the corner is 0.42MPa, and the surface pressure of the first side wall and the second side wall of the sealing ring is 1.05MPa, and the leakage risk is provided. By arranging the arc chamfer at the corner 203 of the sealing ring 20, the surface pressure at the periphery of the corner 203 is similar to the surface pressure of the first side wall 201 and the second side wall 202 of the sealing ring 20, the surface pressure of the whole sealing ring 20 is uniform, and the sealing effect of the sealing member 100 is improved.

In some embodiments of the utility model, R1/L1 satisfies: R1/L1 is more than or equal to 0.11 and less than or equal to 0.16; and/or R1/L2 is more than or equal to 0.11 and less than or equal to 0.16.

Further, setting the radius R1 of the circular arc chamfer to R1/L1 equal to or greater than 0.11 and less than or equal to 0.16, and/or setting the radius R1 of the circular arc chamfer to R1/L2 equal to or greater than 0.11 and less than or equal to 0.16 can make the surface pressure of each portion of the seal ring 20 more uniform, promote the sealing effect of the seal member 100, and promote the reliability and stability of the multi-way valve 1000.

Alternatively, the ratio of the radius R1 of the circular arc chamfer to the length L1 of the first sidewall 201 in the first direction may be 0.11, 0.12, 0.13, 0.14, 0.15, 0.16, etc.; alternatively, the ratio of the radius R1 of the circular arc chamfer to the length L2 of the second sidewall 202 in the second direction may be 0.11, 0.12, 0.13, 0.14, 0.15, 0.16, etc.

The first ribs 21 extend in a first direction, the second ribs 22 extend in a second direction, and the plurality of first ribs 21 intersect the plurality of second ribs 22, so that a seal ring 20 surrounding the outer edge of the relief hole 11 can be formed. Wherein at least part of the first bead 21 forms a first side wall 201 of the sealing ring 20 extending in the first direction and the second bead 22 at least part forms a second side wall 202 of the sealing ring 20 extending in the second direction.

Compared with the sealing rings 20 respectively arranged around the outer edges of the avoidance holes 11, the embodiment of the utility model has the advantages that the plurality of first ribs 21 and the plurality of second ribs 22 are arranged, and the sealing rings 20 are formed by utilizing the intersection of the first ribs 21 and the second ribs 22, so that the manufacturing difficulty can be reduced, the structural strength of the sealing element 100 can be further improved, the sealing element 100 is prevented from being broken due to impact, and the working stability of the sealing element 100 is improved.

The body 1 of the seal 100 is in direct contact with the spool on the side near the center of the circle, and the spool needs to be reciprocally rotated in the operating state, and the seal 100 is susceptible to wear, resulting in seal failure.

Therefore, the multi-way valve 1000 can have both reversing function and proportion adjusting function, realizes integrated arrangement, reduces the number of driving parts, is beneficial to reducing cost, saves installation space, and can realize the purpose of continuous flow.

For example, referring to fig. 3 and 4, an open fitting chamber is formed in the housing 300, and the valve cartridge 400 is mounted in the fitting chamber, and the valve cartridge 400 is rotated with respect to the housing 300. The side wall of the assembly chamber of the housing 300 is provided with a through-hole, which is disposed opposite to the valve cartridge 400 in the radial direction of the valve cartridge, and which communicates with a flow passage for a circulating medium. The valve core 400 is provided with a plurality of switching flow channels, and the switching flow channels can be communicated with different flow through holes, so that the reversing valve of the multi-way valve 1000 can be realized, and the thermal management module with the multi-way valve 1000 can perform mode switching.

In addition, when the multi-way valve 1000 is operated, the valve core 400 rotates, and after the valve core 400 rotates by a certain angle, the switching channel and the through hole start to be conducted, the valve core 400 continues to rotate, the conducting area of the switching channel and the through hole gradually increases, and the flow rate through which the switching channel and the through hole can pass increases. Thus, by controlling the rotation angle of the valve body 400, switching of a plurality of operation modes of the multi-way valve 1000 and flow control can be achieved.

The plurality of avoidance holes 11 and the plurality of communication holes on the sealing piece 100 are arranged in one-to-one correspondence, and the periphery of each avoidance hole 11 is provided with a sealing ring 20, the sealing rings 20 mutually space all the avoidance holes 11, so that the direct communication of the adjacent communication holes can be avoided, and the reliability and the stability of the multi-way valve 1000 are improved.

According to the multi-way valve 1000 provided by the embodiment of the utility model, the switching flow channels are arranged to be communicated with different flow through holes, so that the multi-way valve 1000 can realize the functions of interval reversing and proportion regulation, realize integrated arrangement, reduce the number of driving parts, facilitate the reduction of cost, save the installation space and realize the purpose of continuous flow. By providing the sealing member 100, direct communication between adjacent communication holes is avoided, and reliability and stability of the multi-way valve 1000 are improved.

In some embodiments of the present utility model, the inner wall of the housing 300 is provided with a receiving groove, and the sealing member 100 is provided in the receiving groove. With the above arrangement, the size of the multi-way valve 1000 can be reduced, and the mounting stability of the sealing member 100 can be improved, and the reliability of the multi-way valve 1000 can be improved.

In some embodiments of the utility model, the flow-through holes are at least three, the at least three flow-through holes being spaced apart. The switching flow passage includes a first switching flow passage 41 and a second switching flow passage 42, the first switching flow passage 41 being configured such that one of the through-holes is in switching communication with at least two of the through-holes; the second switching flow passage 42 is configured such that different communication holes are switched to communicate, and the second switching flow passage is also configured such that the number of communication holes that are communicated can be changed. It should be noted that, by switching the flow channels through different flow through holes, the function of the multi-way valve reversing valve can be realized, so that the thermal management module with the multi-way valve reversing valve can perform mode switching.

For example, as shown in fig. 7 to 10, the through-holes may be provided to include a first through-hole 311, a first through-hole 312, a third through-hole 313, a fourth through-hole 321, and a fifth through-hole 322. The first switching flow path 41 may be used to flow the first flow hole 312 and the first flow hole 311, or may be used to flow the first flow hole 312 and the third flow hole 313. Since the first communication hole 312 always has a communication hole communicating with it during the rotation of the valve body 400 to perform the mode switching, the multi-way valve 1000 can be continuously operated, so that the pipe connected thereto always has a liquid flow. In the process of rotating the valve element, the first switching flow passage 41 may be in switching communication with at least a plurality of through holes through different through holes, for example, four or more through holes may be corresponding to the first switching flow passage 41, the flow passages may be switched between the first through hole 312 and the first through hole 311 and the third through hole 313, and then may be in switching communication with the fourth through hole 321 and the fifth through hole 322 through the third through hole 313, so as to ensure the purpose of continuously reversing the multi-way valve 1000.

The second switching flow passage 42 may be used to communicate the fourth flow through hole 321 with the third flow through hole 313, or may be used to communicate the fifth flow through hole 322 with the third flow through hole 313, respectively. The second switching flow passage 42 may be used to communicate two through-holes, and may be used to communicate the fourth through-hole 321 and the fifth through-hole 322 with the third through-hole 313, respectively. Alternatively, the second switching flow passage may be configured to communicate with three or more through-holes, whereby the number of through-holes to be communicated is changed.

In the process of switching the second switching flow path 42 from the communication with the fourth through hole 321 to the communication with the fifth through hole 322, the second switching flow path 42 is simultaneously communicated with the fourth through hole 321 and the fifth through hole 322 and then is separately communicated with the fifth through hole 322 as the valve body 400 rotates. In the process that the second switching flow passage 42 is simultaneously communicated with the fourth flow through hole 321 and the fifth flow through hole 322, along with the rotation of the valve core 400, the area of the second switching flow passage 42 communicated with the fourth flow through hole 321 can be gradually reduced, so that the area of the second switching flow passage 42 communicated with the fifth flow through hole 322 is gradually reduced, and vice versa. Therefore, the proportion adjusting function can be realized, and the purpose of continuous flow in the proportion adjusting process can be realized.

The above-described embodiments are merely exemplary, and do not limit the present utility model, and the present utility model may also provide six through holes or more, and the present utility model is not limited thereto.

According to the multi-way valve 1000 of the embodiment of the utility model, one through hole and at least two through holes can be switched and communicated by arranging the first switching flow passage 41, and different through holes can be switched and communicated by arranging the second switching flow passage 42, and the number of the communicated through holes can be changed, so that the multi-way valve 1000 can have both a reversing function and a proportion adjusting function, realize integrated arrangement, reduce the number of driving parts, facilitate reducing cost, save installation space and realize the purpose of continuous flow.

In some embodiments of the present utility model, the first switching flow path 41 extends along the rotation direction of the valve body 400, and the plurality of through-holes are sequentially arranged in the extending direction of the first switching flow path 41.

For example, referring to fig. 6, the first switching flow passage 41 is provided on the outer peripheral wall of the spool 400, and the first switching flow passage 41 is arranged to extend in the rotation direction of the spool 400. The casing 300 has a plurality of through holes sequentially arranged in the extending direction of the first switching flow channel 41, the first switching flow channel 41 is used for communicating two (or more of course) adjacent through holes, and when the valve core 400 rotates, the first switching flow channel 41 can communicate the through holes with another adjacent through hole.

In a practical arrangement, as shown in fig. 7 to 10, the first through-hole 311, the second through-hole 312, and the third through-hole 313 may be arranged in this order, and when the first switching flow passage 41 communicates the first through-hole 311 and the second through-hole 312, the valve body 400 may be rotated so that the first switching flow passage 41 may communicate the second through-hole 312 and the third through-hole 313, and vice versa. Thereby, the switching stability of the first switching flow path 41 is advantageously improved, and the reliability of the multi-way valve 1000 is improved.

In some embodiments of the present utility model, the housing 300 is provided with at least two rows of through-hole groups arranged in the direction in which the central axis of the valve body 400 extends, each of the at least two rows of through-hole groups including a plurality of through-holes arranged in the direction in which the valve body 400 rotates, the at least two rows of through-hole groups including a first row of through-hole groups 31 and a second row of through-hole groups 32, at least two through-holes in the first row of through-hole groups 31 being in switching communication by the first switching flow passage 41, the second switching flow passage 42 being configured to communicate the through-holes in the first row of through-hole groups 31 and the second row of through-hole groups 32.

Wherein the at least two rows of through-hole groups include a first row of through-hole groups 31 and a second row of through-hole groups 32, at least two of the through-holes in the first row of through-hole groups 31 are switched in communication by a first switching flow passage 41, and a second switching flow passage 42 is configured for communicating the through-holes of the first row of through-hole groups 31 and the second row of through-hole groups 32.

For example, as shown in fig. 7 to 10, a first row of through-hole groups 31 may be provided including a first through-hole 311, a second through-hole 312, and a third through-hole 313, the first through-hole 311, the second through-hole 312, and the third through-hole 313 being sequentially arranged in the rotation direction of the spool 400, and a second row of through-hole groups 32 including a fourth through-hole 321 and a fifth through-hole 322, the fourth through-hole 321 and the fifth through-hole 322 being sequentially arranged in the rotation direction of the spool 400.

The first switching flow path 41 may communicate the first flow hole 311 with the second flow hole 312, or may communicate the second flow hole 312 with the third flow hole 313. The second switching flow passage 42 may communicate the fourth flow through hole 321 with the third flow through hole 313, may communicate both the fourth flow through hole 321 and the fifth flow through hole 322 with the third flow through hole 313, and may communicate the fifth flow through hole 322 with the third flow through hole 313. The above embodiments are merely exemplary and do not limit the present utility model.

Through the arrangement, the valve core 400 can communicate the communication through holes of different through hole groups, so that the arrangement of the communication through holes can be flexible, the practicability of the multi-way valve 1000 is improved, and the layout difficulty of the multi-way valve 1000 is reduced.

In some embodiments of the present utility model, the second switching flow passage 42 is disposed in the valve core 400, and the second switching flow passage 42 is provided with at least one first communication hole 421 and a plurality of second communication holes 422, where the first communication hole 421 is in communication with or offset from the first row of through hole groups 31, and the second communication hole 422 is in communication with or offset from the second row of through hole groups 32.

For example, referring to fig. 4 to 7, the second switching flow passage 42 is provided in the valve body 400 and is spaced apart from the first switching flow passage 41, and a communication hole is formed in the side wall of the valve body 400 corresponding to the second switching flow passage 42, and the communication hole penetrates the side wall of the valve body 400 in the radial direction of the valve body 400. The second switching flow passage 42 is provided with at least one first communication hole 421 and a plurality of second communication holes 422, and the first communication holes 421 and the second communication holes 422 are sequentially arranged in the axial direction of the valve body 400. The first through holes 421 are disposed opposite to the first row of through holes 31, and the first through holes 421 may be communicated with or staggered from the through holes of the first row of through holes 31; the second communication holes 422 are disposed opposite to the second row of through holes 32, and the second communication holes 422 may be disposed in communication with or offset from the through holes of the second row of through holes 32.

It can be appreciated that by providing the first row of through holes 31 and the second row of through holes 32 to be respectively communicated with the second switching flow channel 42 through different communication holes, the situation that the first row of through holes 31 and the second row of through holes 32 are directly communicated can be avoided, which is beneficial to improving the flow stability of the liquid in the second switching flow channel 42 and improving the reliability of the multi-way valve 1000. Further, by arranging the second switching flow passage 42 inside the valve body 400, the internal space of the valve body 400 can be reasonably utilized, and the flexibility of the shape setting of the second switching flow passage 42 can be increased.

In some embodiments of the present utility model, the first communication hole 421 is configured to communicate with at least two communication holes at the same time, and the second switching flow passage 42 communicates with one of the communication holes through the second communication hole 422. That is, when the second communication hole 422 rotates to be blocked by the housing 300 without fluid inflow during rotation of the valve body 400, the first communication hole 421 may also have a communication hole communicating therewith, so that the first communication hole 421 may be switched to communicate with a different communication hole on the housing 300 through the second switching flow passage 42 and the second communication hole 422, and the number of the communication fluid holes may also be changed. Thereby, the structure of the valve cartridge 400 is simplified.

In some embodiments of the present utility model, as shown in fig. 6, the extension length of the first communication hole 421 in the circumferential direction of the valve body 400 is at least twice the extension length of the second communication hole 422.

In some embodiments of the present utility model, for example, referring to fig. 6, in the rotation direction of the spool 400, both sides of the first switching flow path 41 are provided with the first communication holes 421. With the above arrangement, in the process of rotating the valve body 400, the first row of through holes 31 always have the through holes in communication with the first switching flow passage 41 and/or the first through holes 421, so that the purpose of continuous flow can be achieved.

For example, as shown in fig. 7 to 10, the first row of through-hole groups 31 may be provided to include a first through-hole 311, a second through-hole 312, and a third through-hole 313, the first through-hole 311, the second through-hole 312, and the third through-hole 313 being sequentially arranged in the circumferential direction of the valve body 400, the first switching flow passage 41 being configured to communicate adjacent two of the first through-hole 311, the second through-hole 312, and the third through-hole 313, and the first through-holes 421 may be provided on both sides of the first switching flow passage 41 in the rotational direction of the valve body 400, respectively. When the first switching flow path 41 communicates the first communication hole 311 and the second communication hole 312, the corresponding-side first communication hole 421 may communicate with the third communication hole 313, and when the first switching flow path 41 communicates the second communication hole 312 and the third communication hole 313, the corresponding-side first communication hole 421 may communicate with the first communication hole 311.

In some embodiments of the present utility model, the first communication hole 421 and/or the first switching flow passage 41 are disposed opposite to the at least one second communication hole 422 in the extending direction of the central axis of the spool 400. For example, as shown in fig. 6, the first communication hole 421 may be provided opposite to the at least one second communication hole 422 in the extending direction of the central axis of the valve body 400; alternatively, the first switching flow passage 41 may be provided so as to be disposed opposite to the at least one second communication hole 422; alternatively, the first communication hole 421 and the first switching flow path 41 may be provided so as to face the at least one second communication hole 422. Through the arrangement, centralized arrangement is realized, which is beneficial to reducing the size of the multi-way valve 1000, and further reducing the overall size of the multi-way valve 1000.

In some embodiments of the present utility model, the second communication hole 422, which is disposed opposite each of the first communication holes 421, is located at an end of the corresponding first communication hole 421 facing away from the first switching flow path 41. For example, referring to fig. 6, in the extending direction of the central axis of the valve body 400, each of the first communication holes 421 is held in opposition to one of the second communication holes 422, and the second communication hole 422 in opposition to the first communication hole 421 is located at an end of the first communication hole 421 facing away from the first switching flow path 41. Thus, when the second communication hole 422 facing the first communication hole 421 is offset from the communication holes of the second row of through holes 32, the first communication hole 421 can still communicate with the same communication hole of the first row of through holes 31. Thus, the communication between the first communication hole 421 and the different communication holes in the second row of through-hole groups 32 can be realized, which is advantageous for improving the practicality of the multiway valve 1000.

Further, referring to fig. 6, in the extending direction of the central axis of the valve body 400, both ends of the first switching flow path 41 are provided with a second communication hole 422 facing each other. For example, as shown in fig. 7 to 8, when the first switching flow channel 41 communicates with the first and second communication holes 311 and 312, the first communication hole 421 located on the right side may communicate with the third communication hole 313. At this time, the valve body 400 may be rotated to the first switching position so that the second communication hole 422 corresponding to the first communication hole 421 located at the right side may communicate with the fifth communication hole 322; alternatively, the valve body 400 may be rotated to the second switching position so that the second communication hole 422 at the left end of the first switching flow path 41 may communicate with the fourth communication hole 321; alternatively still, the valve body 400 may be rotated between the first switching position and the second switching position such that the second communication hole 422 corresponding to the first communication hole 421 located on the right side may communicate with the fifth communication hole 322, and such that the second communication hole 422 located on the left end of the first switching flow path 41 may communicate with the fourth communication hole 321.

Through the above arrangement, the second switching flow channel 42 can be simultaneously communicated with two through holes in the second row of through hole groups 32, which is favorable for realizing the proportion adjusting function, and in the process of switching the through holes of the second switching flow channel 42, liquid always flows in the second switching flow channel 42, thereby realizing no flow break and improving the stability of the multi-way valve 1000.

In some embodiments of the utility model, the rotation angle of the spool 400 is 90 °. Specifically, the rotation angle of the spool 400 may be set to 85 °; alternatively, the rotation angle of the valve cartridge 400 may be set to 75 °, or alternatively, the rotation angle of the valve cartridge 400 may be set to 65 °, which is not limited in the present utility model. Preferably, the rotation angle of the spool 400 may be set to 80 °.
