For example, referring to fig. 4 and 7, an open fitting chamber is formed in the housing 1, and the valve spool 2 is mounted in the fitting chamber, and the valve spool 2 rotates relative to the housing 1. The side wall of the assembly cavity of the shell 1 is provided with a communication through hole which is arranged opposite to the valve core 2 along the radial direction of the valve core 2 and is communicated with a flow passage for circulating media. The valve core 2 is provided with a plurality of switching flow passages, and the switching flow passages can be communicated with different flow through holes, so that the reversing valve of the multi-way valve 100 can be realized, and the thermal management module with the multi-way valve 100 can perform mode switching.

In addition, when the multi-way valve 100 is operated, the valve core 2 rotates, and after the valve core 2 rotates by a certain angle, the switching channel and the through hole start to be conducted, the area of the switching channel conducted with the through hole is gradually increased, and the flow rate through which the switching channel can pass is also increased. Thus, by controlling the rotation angle of the valve element 2, switching of a plurality of operation modes and flow control of the multi-way valve 100 can be achieved.

The plurality of avoidance holes 31 and the plurality of communication holes on the sealing piece 3 are arranged in one-to-one correspondence, and the periphery of each avoidance hole 31 is provided with a sealing ring, the sealing rings are used for mutually spacing all the avoidance holes 31, so that the direct communication of the adjacent communication holes can be avoided, and the reliability and the stability of the multi-way valve 100 are improved.

In some embodiments of the present utility model, the multi-way valve 100 further includes a bearing 6, and a three-dimensional structure and a cross-sectional view of the bearing 6 are given with reference to fig. 10 and 11. The bearing 6 is arranged between the valve core 2 and the shell 1, and the valve core 2 can rotate relative to the shell 1 through the cooperation of the bearing 6. Wherein, referring to fig. 9, the bearing 6 comprises a first bearing 61, which also comprises a second bearing 62. The first bearing 61 and the second bearing 62 are disposed at intervals in the axial direction of the multi-way valve 100, and the first bearing 61 and the second bearing 62 are connected to both ends of the spool 2, respectively.

By arranging the first bearing 61 and the second bearing 62 to be matched with the valve core 2, the movement smoothness of the valve core 2 can be improved, the valve core 2 is uniformly stressed, and the movement stability of the valve core 2 is improved. And when one of the first bearing 61 and the second bearing 62 is worn out and can not work normally, the valve core 2 and the other bearing can still rotate normally when being matched with each other, the movement stability of the valve core 2 is improved, and the service life of the multi-way valve 100 is prolonged.

In some embodiments of the present utility model, referring to FIG. 9, the multi-way valve 100 further includes a shaft seal member 7, the shaft seal member 7 being provided between the valve body 2 and the housing 1, a distance L between the first bearing 61 and the shaft seal member 7 in an axial direction of the first bearing 61 is 1 mm.ltoreq.L.ltoreq.H/2, and referring to FIGS. 9 and 11, H is an axial length of the first bearing 61

The first bearing 61 may be located on either side of the shaft seal 7 in the axial direction, and preferably the first bearing 61 is located above the shaft seal 7 in the axial direction of the multi-way valve 100 such that the shaft seal 7 is located between the first bearing 61 and the second bearing 62, which may have more advantageous effects for the position retention and the face pressure retention of the shaft seal 7.

The distance L between the first bearing 61 and the shaft seal 7 satisfies: l is 1mm or more and 1mm or less than half the axial length of the first bearing 61. Too large or too small a distance between the first bearing 61 and the shaft seal 7 affects the rotation of the valve spool 2. When the distance between the first bearing 61 and the shaft seal 7 is too large, the protection effect of the bearing 6 and the shaft seal 7 is weak, and when the distance between the first bearing 61 and the shaft seal 7 is too small, the materials generated by abrasion of the shaft seal 7 easily enter the gap between the bearing 6 and the valve core 2, so that the abrasion of the bearing 6 and the valve core 2 is increased, and the service life of the valve core 2 is reduced. Setting the distance L between the first bearing 61 and the shaft seal 7 within the above range can protect the shaft seal 7 well while ensuring the normal operation of the bearing 6.

In some embodiments of the utility model, a wear layer is provided on the inner race of the bearing 6 to reduce wear when mated with the valve spool 2, extending the useful life of the bearing 6 and valve spool 2.

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 21 and a second switching flow passage 22, the first switching flow passage 21 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 22 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. 5 and 8, the circulation through holes may be provided to include a first circulation through hole 131, a first circulation through hole 132, a third circulation through hole 133, a fourth circulation through hole 141, and a fifth circulation through hole 142. The first switching flow path 21 may be used to communicate the first communication hole 132 with the first communication hole 131, or may be used to communicate the first communication hole 132 with the third communication hole 133. Since the first communication hole 132 always has a communication hole communicated with the valve core 2 during the rotation of the valve core to perform the mode switching, the purpose of continuous flow of the multi-way valve 100 can be achieved, so that the pipe connected thereto always has a liquid flow. In the process of rotating the valve element 2, at least a plurality of the through holes may be switched to communicate with each other through different through holes, for example, the first switching flow passage 21 may correspond to four or more through holes, the flow passage may be switched to the first through hole 131 and the third through hole 133 through the first through hole 132, and then may be switched to communicate with the fourth through hole 131 and the fifth through hole 132 through the third through hole 133, so that the purpose of reversing the multi-way valve 100 is ensured.

The second switching flow passage 22 may be used to communicate the fourth flow through hole 141 with the third flow through hole 133, or may be used to communicate the fifth flow through hole 142 with the third flow through hole 133. The second switching flow passage 22 may be used to communicate two through-holes, and may be used to communicate the fourth through-hole 141 and the fifth through-hole 142 with the third through-hole 133, respectively. Alternatively, the second switching flow passage 22 may be used to communicate 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 passage 22 from the communication with the fourth through hole 141 to the communication with the fifth through hole 142, the second switching flow passage 22 is simultaneously communicated with the fourth through hole 141 and the fifth through hole 142 and then is separately communicated with the fifth through hole 142 as the valve body 2 rotates. In the process of simultaneously communicating the second switching flow passage 22 with the fourth through hole 141 and the fifth through hole 142, the area of the second switching flow passage 22 communicating with the fourth through hole 141 may be gradually reduced along with the rotation of the valve body 2, so that the area of the second switching flow passage 22 communicating with the fifth through hole 142 may be gradually increased, 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.
