Further, as shown in fig. 6, the housing 10 further includes a plurality of flow guiding portions 13 arranged at intervals along the circumferential direction of the housing body 11, one side of each flow guiding portion 13 is connected to the outer circumferential surface of the housing body 11, the other side is connected to the first end surface 121, flow guiding channels are provided in each flow guiding portion 13, and the inner ports 102a, the flow guiding channels, and the outer ports 102b are sequentially communicated one by one to form the flow passage 102.

In this embodiment, the flow guiding portion 13 extends radially outward from the outer circumferential surface of the shell body 11, and both sides of the flow guiding portion 13 are respectively connected with the shell body 11 and the annular boss 12, so as to play a certain role in structural reinforcement. Optionally, the shell body 11, the annular boss 12 and the flow guiding portion 13 are integrally formed, for example, integrally formed by an injection molding process, which not only simplifies the manufacturing process, but also further improves the structural strength of the shell 10. Each of the flow guiding portions 13 is hollow to form a flow guiding channel, one end of the flow guiding channel is communicated with the inner port 102a, and the other end is communicated with the outer port 102b, so as to form a flow passage 102. In this way, the medium inside the multi-channel valve 100 can be conveyed into the diversion flow channel through the inner port 102a, and conveyed to the corresponding outer port 102b under the guidance of the diversion flow channel to be output to an external pipeline; alternatively, the media may enter the diversion flow path from the outer port 102b and be delivered to the corresponding inner port 102a into the interior of the multi-channel valve 100 under the guidance of the diversion flow path.

It will be appreciated that the number of flow guides 13 is adapted to the number of flow channels 102, for example, in the present embodiment, the multi-channel valve 100 has 12 flow channels 102, and accordingly, the outer periphery of the housing body 11 is circumferentially provided with 12 flow guides 13 at intervals. It should be noted that the shapes of the flow guiding portions 13 may be the same or different, and specifically, the flow guiding portions 13 may be designed according to the relative positions of the corresponding inner ports 102a and outer ports 102 b. Alternatively, the plurality of flow guides 13 are spaced and uniformly arranged along the outer circumferential surface of the case body 11. Alternatively, the guides 13 may be located at the same height position or may be disposed at positions close to the same height position of the multi-channel valve 100. So for a plurality of water conservancy diversion portions 13 arrange more regularly, be favorable to the miniaturization of multichannel valve 100 whole volume.

In order to more gently guide the medium to change the flowing direction, the flow guide flow channel is further arranged in an arc-shaped flow channel. Specifically, the diversion flow channel extends outward from the periphery of the inner port 102a along the radial direction of the shell body 11 for a certain distance and then bends downward to be connected with the periphery of the outer port 102b, so that the diversion flow channel is arranged in an arc shape as a whole. Thus, the medium can be guided smoothly to change the flow direction, the flow resistance of the medium can be reduced, and the medium is prevented from generating large impact on the inner wall surface of the flow guide part 13 in the flowing process.

In order to enable the multi-channel valve 100 to realize more flow channel mode switching, referring to fig. 3 and 9, in one embodiment, a plurality of switching channels are provided, the plurality of switching channels includes a first switching channel 201 and a second switching channel 202, the first switching channel 201 is used for communicating two adjacent internal ports 102a, the second switching channel 202 is used for communicating two non-adjacent internal ports 102a, and the valve spool 20 rotates to make the first switching channel 201 and/or the second switching channel 202 and different internal ports 102a switch and communicate.

In this embodiment, the first switching channel 201 is used to communicate two adjacent inner ports 102a, which is beneficial to realize the communication between two adjacent circulation channels 102; the second switching passage 202 is used to communicate the non-adjacent two inner ports 102a, which is advantageous for communication between the non-adjacent two flow-through passages 102. The spool 20 is rotated to switch the first switching passage 201 to communicate with the different inner ports 102a and/or the second switching passage 202 to communicate with the different inner ports 102a, so that the multi-channel valve 100 can be switched between a plurality of flow paths and a plurality of modes by rotating the spool 20. For example, when the valve core 20 rotates to the first position, the first switching passage 201 communicates two adjacent inner ports 102a, and the second switching passage 202 does not communicate two non-adjacent inner ports 102a, so as to realize the first flow passage mode; when the spool 20 rotates to the second position, the second switching passage 202 communicates the non-adjacent two inner ports 102a, and the first switching passage 201 does not communicate the adjacent two inner ports 102a, to realize the second flow passage mode; when the spool 20 rotates to the third position, the first switching passage 201 communicates two adjacent inner ports 102a, and the second switching passage 202 communicates two non-adjacent inner ports 102a, to realize a third flow passage mode. In this way, the first switching channel 201 and the second switching channel 202 are respectively in switching communication with different inner ports 102a (i.e., the flow channels 102), so that the switchable modes of the multi-channel valve 100 can be further increased, and the cost and the control difficulty can be further reduced.

Optionally, N first switching channels 201, 1 second switching channel 202, and 2 (N + 1) inner ports 102a are provided, where N is an integer greater than or equal to 2. For example, as shown in fig. 3 and 10, in the present embodiment, the multi-channel valve 100 has 12

flow channels

102, and 12 corresponding inner ports 102a are provided, so that 5 first switching channels 201 and 1 second switching channel 202 may be provided in the valve body 20 to satisfy the switching of different flow channel modes. Of course, in other embodiments, the number of the first switching channels 201 and the second switching channels 202 may be adaptively adjusted according to the number of the circulation channels 102.

Further, as shown in fig. 3 and 4, in an embodiment, a spacing portion 14 is formed between any two adjacent inner ports 102a, in the initial position, each first switching passage 201 is correspondingly communicated with one set of two adjacent inner ports 102a, and the second switching passage 202 is communicated with two inner ports 102a separated by one set of two adjacent inner ports 102a; each of the first switching passages 201 and the second switching passages 202 crosses over one of the spacers 14 and then communicates with the inner port 102a adjacent to the spacer 14 every time the spool 20 rotates by a predetermined angle.

For example, in the present embodiment, 12 inner ports 102a are provided at intervals in the circumferential direction on the inner circumferential surface of the housing body 11, and one partition 14 is formed between any two adjacent inner ports 102a. For ease of illustration, the inner ports 102a are numbered in the order of N1 to N12. Taking the switching process of one of the first switching channels 201 and the second switching channel 202 as an example, as shown in fig. 3, in the initial position, one of the first switching channels 201 communicates the adjacent N2 inner port 102a and N3 inner port 102a, and two ends of the second switching channel 202 communicate the N1 inner port 102a and N4 inner port 102a, respectively. As shown in fig. 4, when the valve element 20 rotates clockwise by a predetermined angle, the first switching passage 201 passes through one of the partition portions 14 to communicate the adjacent N3 inner port 102a with the N4 inner port 102a, and the second switching passage 202 passes through one of the partition portions 14 to communicate the N2 inner port 102a with the N5 inner port 102a. The other first switching channels 201 are switched in a similar manner. The preset angle theta can be set according to actual needs, and optionally, theta is more than or equal to 10 degrees and less than or equal to 30 degrees. For example, the preset angle θ may be set to 10 °, 15 °, 30 °, and so on.

Referring to fig. 9 and 10, in one embodiment, the valve core 20 is provided at an outer circumferential surface thereof with a guide recess recessed toward a center of the valve core 20, and the guide recess forms a first switching passage 201. Thus, the structure of the first switching passage 201 can be simplified, and the valve element 20 can be conveniently produced and manufactured. Optionally, the first switching channel 201 (i.e., the diversion cavity) is configured like a semicircle to reduce the medium flow resistance.
