As shown in fig. 2 and 6, a part of the relief channel 31 is disposed inside the seal member 30 and extends along the circumferential direction and/or the axial direction of the seal member 30, and if there is a straight line passing through one of the openings and the axis of the seal member 30, the other opening does not need to be disposed on the straight line, so that the flow path of the medium inside the seal member 30 may be curved.

For example, a part of the relief passage 31 is provided inside the seal member 30 and extends in the circumferential direction of the seal member 30, the opening of the relief passage 31 toward the valve housing 10 is a first opening 311, the opening of the relief passage 31 toward the valve element 20 is a second opening 312, and the second opening 312 is located on the right side of the first opening 311; or, a part of the escape passage 31 is arranged inside the sealing member 30 and extends along the axial direction of the sealing member 30, the opening of the escape passage 31 facing the valve housing 10 is a first opening 311, the opening of the escape passage 31 facing the valve core 20 is a second opening 312, and the second opening 312 is positioned above the first opening 311; or, a part of the escape passage 31 is provided inside the sealing member 30 and extends along the circumferential direction and the axial direction of the sealing member 30, the opening of the escape passage 31 toward the valve housing 10 is a first opening 311, the opening of the escape passage 31 toward the valve core 20 is a second opening 312, and the second opening 312 is positioned above and to the right of the first opening 311; of course, the above is merely an example, and is not meant to limit the present invention, and the second opening 312 may be located at the left, lower, upper left, etc. of the first opening 311, which is not described herein.

As shown in fig. 4 (a flow path in which a black line is a medium in the drawing), in some embodiments of the present invention, the first opening 311 of the relief passage 31 is located in front of the valve element 20, the second opening 312 is located behind the valve element 20, and the medium flows from the second communication passage 22 to the rear of the valve element 20, flows through the seal 30 to the front of the valve element 20, and then flows out of the flow port 11.

The valve core 20 rotates to enable the first communication channel 21 to be communicated with different circulation ports 11 in a changing way and/or the second communication channel 22 to be communicated with different circulation ports 11 in a changing way, and multiple modes are achieved through rotating the valve core 20.

For example, the spool 20 rotates so that the first communication passage 21 is in communication with the different communication port 11, and the two communication ports 222 of the second communication passage 22 are not connected to the communication port 11 at all times; alternatively, the valve spool 20 is rotated so that the second communication passage 22 is in communication with the different communication port 11, and the first communication passage 21 is not in communication with the communication port 11 at all times; still alternatively, the valve element 20 is rotated so that the first communication passage 21 is in communication with the different flow ports 11 and the second communication passage 22 is in communication with the different flow ports 11, and rotation of a single valve element 20 simultaneously effects communication of the first communication passage 21, the second communication passage 22, and the different flow ports 11.

According to the multi-way valve 100 of the embodiment of the invention, the first communication channel 21 and the second communication channel 22 are arranged, and the first communication channel 21 and the second communication channel 22 are respectively distributed on the outer peripheral wall and the inner part of the valve core 20, so that the space of the valve core 20 is fully utilized, the space utilization rate is improved, more modes of conversion are realized under the same volume limitation, the use of a simple multi-way valve is reduced, and the cost and the control difficulty are reduced; through arranging a plurality of communication ports 11 to be communicated with the first communication channel 21 and the second communication channel 22 in a conversion way, a conversion mode is further increased, and the cost and the control difficulty are further reduced; by providing the sealing member 30 between the valve housing 10 and the valve core 20, and providing the sealing member 30 with a plurality of avoiding passages 31 partially provided inside the sealing member 30, the convertible mode is further increased and the user's choice is increased while ensuring that the first communication passage 21 and the second communication passage 22 do not have series flow.

In some embodiments, the seal 30 is secured to the inner wall of the valve housing 10 such that the seal 30 is relatively stationary with respect to the valve housing 10 and the valve core 20 rotates with respect to the seal 30.

Alternatively, the sealing member 30 is integrally designed with the valve housing 10, reducing the number of parts and facilitating installation.

In some examples of the invention, the seal 30 is secured to the valve core 20 for synchronous rotation with the valve core 20, at which time the seal 30 is secured to the outer peripheral wall of the valve core 20 such that the seal 30 is relatively stationary with respect to the valve core 20 and seal 30 rotate with respect to the valve housing 10. It should be noted that, the number of the avoidance channels 31 corresponding to the flow ports 11 is not limited by the number of the flow ports 11, and the number of the avoidance channels 31 may be greater than the number of the flow ports 11, for example, sixteen flow ports 11 are arranged in four rows and four columns, twenty avoidance channels 31 are arranged in four rows and five columns, when the sealing element 30 is in the first state, the four rows and four columns on the left side of the four rows and five columns of the avoidance channels 31 are correspondingly communicated with the four rows and four columns of the flow ports 11, and the sealing element 30 is moved to enable the sealing element 30 to be in the second state, and the four rows and four columns on the right side of the four rows and five columns of the avoidance channels 31 are correspondingly communicated with the four rows and four columns of the flow ports 11. Optionally, the sealing element 30 and the valve core 20 are integrally designed, so that the number of parts is reduced, and the installation is convenient.

For example, when the valve core 20 rotates to make the first communication channel 21 and the plurality of communication ports 11 change communication, the seal member 30 is provided with the avoiding channel 31 corresponding to the communication port 11, and the medium in one first communication channel 21 does not flow into the other first communication channel 21, but flows into the corresponding avoiding channel 31 to enter the corresponding communication port 11; or, when the valve core 20 rotates to enable the second communication channel 22 to be in communication with the plurality of communication ports 11 in a changing way, the sealing member 30 is provided with the avoiding channels 31 corresponding to the communication ports 11, and the medium in one second communication channel 22 does not flow into the other second communication channel 22, but flows into the corresponding avoiding channel 31 to enter the corresponding communication port 11; or, when the valve core 20 rotates to make the first communication channel 21 and the second communication channel 22 in communication with the plurality of communication ports 11, the sealing member 30 is provided with the avoiding channel 31 corresponding to the communication port 11, so that the medium in the first communication channel 21 does not flow into the second communication channel 22, but flows into the corresponding avoiding channel 31 corresponding to the second communication channel into the corresponding communication port 11, and certainly, after the valve core is arranged, the medium in the second communication channel 22 also does not flow into the first communication channel 21, thereby the flow passage of the medium is clearer.

More specifically, the material of the sealing member 30 is a material having a certain elasticity such as sponge, rubber, etc., so that a certain pressure is provided between the sealing member 30 and the valve housing 10, the valve core 20, and the sealing property is improved.

In some embodiments, the number of the first communication channels 21 is plural, and the plurality of the first communication channels 21 are provided to communicate with more flow ports 11, so as to control the plurality of flow ports 11. The plurality of first communication passages 21 are provided on the spool 20, and when the spool 20 rotates, the plurality of first communication passages 21 all follow the spool 20 to rotate.

Further, the extending directions of the at least two first communicating channels 21 are different, and by setting the extending directions of the at least two first communicating channels 21 to be different, the first communicating channels 21 can communicate with the flow ports 11 at more positions, so as to realize the communication of the flow ports 11 at different directions. For example, the first communication passage 21 may be horizontally extended to communicate with two horizontally arranged flow ports 11; the first communication channel 21 may also extend vertically and communicate with two vertically arranged flow openings 11; the first communication channel 21 may also be inclined by forty-five degrees, and is communicated with two obliquely arranged flow ports 11; of course, the first communication channel 21 may extend in other directions to provide various communication options, which have the same effect and are not described herein.

Further, a part of the first communication channels 21 extend along the axial direction of the valve core 20, a part of the first communication channels 21 extend along the circumferential direction of the valve core 20, and a plurality of communication modes of the circulation ports 11 are provided by arranging a part of the first communication channels 21 to extend along the axial direction of the valve core 20 and a part of the first communication channels 21 to extend along the axial direction of the valve core 20, so that the requirements of customers are met.

As shown in fig. 1, specifically, the first communication passage 21 is a groove on the valve body 20, the notch faces the valve housing 10, and the groove communicates with the two flow ports 11, so that the medium entering from one of the flow ports 11 flows to the other flow port 11 through the groove, and communication between the two flow ports 11 is achieved.

In some embodiments, the valve cartridge 20 is one or a combination of any of a spool valve, ball valve, butterfly valve. For example, the valve core 20 is a spool valve, so that the first communication channel 21 and the second communication channel 22 are conveniently positioned; alternatively, the valve core 20 is a ball valve, so that the space utilization rate is improved; or, the valve core 20 is a butterfly valve, and is easy to control.

It should be noted that, the valve core 20 can be rotated to control the flow, the communication area of the communication port 11 and the notch or the communication port 222 is different when in communication, the flow of the medium is changed, the communication area is small, the flow is small, the communication area is large, the flow is large, and the valve core 20 can be rotated to adjust the size of the communication area, thereby controlling the flow of the medium.

More specifically, the diameter of the spool 20 is less than 150 millimeters.

In some embodiments, the number of the second communication channels 22 is plural, and the second communication channels 22 are arranged to communicate with different flow ports 11, so that the communication channels of the flow ports 11 are further increased on the basis of the arrangement of the first communication channels 21, thereby providing more choices.

Specifically, in the axial direction of the valve core 20, the communication port 222 of a part of the second communication channel 22 is disposed opposite to the first communication channel 21, and by disposing the communication port 222 of the second communication channel 22 opposite to the first communication channel 21, when the communication port 222 of the second communication channel 22 communicates with the communication port 11, the first communication channel 21 may also communicate with another communication port 222, so that the first communication channel 21 and the second communication channel 22 work simultaneously. For example, the axial direction of the valve core 20 is vertical, the communication port 222 of the second communication channel 22 is located below the first communication channel 21, at least four communication ports 11 arranged up and down are arranged on the valve housing 10, two communication ports 11 are communicated through the second communication channel 22, and the other two communication ports 11 are communicated through the first communication channel 21, so that the first communication channel 21 and the second communication channel 22 work simultaneously.

Optionally, the valve housing 10 is provided with a connection plane 12, the connection plane 12 is arranged parallel to the rotation axis of the valve core 20, and the plurality of flow ports 11 are all arranged on the connection plane 12, so that the connection of the multi-way valve 100 with an external device is facilitated by arranging the connection plane 12. For example, the external device is an external pipe, the external pipe is inserted into the circulation port 11, and the position of the circulation port 11 is easily identified by providing the connection plane 12 on the valve housing 10, so that the connection is facilitated.

As shown in fig. 1 and 3, in some embodiments, the plurality of circulation ports 11 are arranged in a plurality of rows and a plurality of columns at uniform intervals, and the arrangement of the circulation ports 11 is clear and regular by arranging the plurality of circulation ports 11 in a plurality of rows and a plurality of columns, so that the positions of the circulation ports 11 are further conveniently identified, the circulation ports 11 are easily positioned, and the installation error is avoided. For example, sixteen circulation ports 11 are arranged in four rows and four columns, so that each circulation port 11 can be rapidly positioned; of course, the plurality of flow ports 11 may be configured as three rows and three columns, five rows and five columns, three rows and four columns, three rows and five columns, four rows and five columns, and the like, which have the same effect and are not described herein.

Of course, the plurality of flow openings 11 may be unevenly disposed, for example, the distance between two adjacent flow openings 11 is different, the third flow opening between two flow openings 11 is sealed, etc., and the plurality of rows and columns of flow openings may be in matrix or staggered form, so as to adapt to more various working conditions.
