In addition, because under case 20 normal operating condition, need to rotate reciprocally in the product life cycle, wearing and tearing can appear in sealing member 30 live time for a long time, lead to multichannel diverter valve 100 to leak, consequently the utility model discloses in, lie in one side of sealing member 30 towards case 20 with wear-resisting layer to reduce case 20 and to the wearing and tearing of body 31 at the rotation in-process, do benefit to the effect that plays protection sealing member 30, and then do benefit to the life who prolongs sealing member 30.

Wherein, the material of wearing layer is that coefficient of friction is little and wear-resisting material, for example: the wearing layer can adopt the fluoroplastic film, or PTFE (polytetrafluoroethylene) class material etc. from this, be convenient for make the wearing layer have wear-resisting and the little effect of coefficient of friction, thereby be convenient for reduce case 20 and rotate the wearing and tearing of in-process to body 31, and do benefit to and reduce the frictional force between sealing member 30 and case 20, thereby play lubricated effect between sealing member 30 and case 20, prolong the life of sealing member 30, simultaneously, can make the torsion of case 20 keep in a less within range.

Of course, the material of the wear-resistant layer may be any material meeting the performance requirement, and is not limited herein.

In other embodiments, the wear-resistant layer is configured as a coating film, and a fluoroplastic film such as PTFE (polytetrafluoroethylene) material can be used for the coating film to provide wear resistance, lubrication and the like, which is beneficial to improving the frictional wear performance of the coating film.

In actual production, the clad film is chemically treated on the side facing the body 31, and the body 31 is chemically treated on the side facing the clad film, then the clad film and the body 31 are assembled and injection molded to make the clad film and the body 31 have the same shape, and then the clad film is punched by a punching tool to make the clad film have a through hole corresponding to the relief through hole 311 of the body 31.

In some embodiments, as shown in fig. 5, the plurality of bypass through holes 311 are arranged in a plurality of rows and columns, and the number of the bypass through holes 311 arranged in the circumferential direction of the body 31 is smaller than the number of the bypass through holes 311 arranged in the axial direction of the body 31.

For example, as shown in fig. 5, the bypass through holes 311 are provided with six, wherein the bypass through holes 311 are distributed in three rows and two columns in the axial direction of the body 31, that is, each row has two bypass through holes 311 distributed at intervals in the circumferential direction of the body 31, and each column has three bypass through holes 311 distributed at intervals in the axial direction of the body 31.

Therefore, the circumferential dimension of the body 31 is convenient to control, the material of the body 31 is saved, and the miniaturization and lightweight design of the body 31 are realized.

In some embodiments, the switching passage 21 is plural, as shown in fig. 2, the plural switching passages 21 include a first communication passage 211 and a second communication passage 212, the first communication passage 211 extends along the outer peripheral wall of the spool 20, the second communication passage 212 includes an inner-layer flow passage through which the two communication ports communicate and two communication ports located on the outer peripheral wall of the spool 20 located inside the spool 20, and the spool 20 rotates so that the first communication passage 211 is switched to communicate with different flow-through holes 11 and/or the second communication passage 212 is switched to communicate with different flow-through holes 11.

It is understood that the first communicating channel 211 is used to communicate with the two circulation through holes 11, and by providing the first communicating channel 211 on the outer peripheral wall of the valve spool 20 and the first communicating channel 211 communicating with the two circulation through holes 11, the valve spool 20 is rotated to communicate the first communicating channel 211 with the different circulation through holes 11, thereby achieving switching of the modes. In some examples of the present invention, the first communication channel 211 may be configured to communicate two adjacent flow through holes 11, facilitating the production of the valve element 20, e.g., two flow through holes 11 are adjacent.

The second communicating channel 212 is used for communicating the two circulation through holes 11, the second communicating channel 212 comprises an inner layer flow channel and two communicating ports, the two communicating ports are communicated through the inner layer flow channel, the two communicating ports are located on the outer peripheral wall of the valve core 20, the inner layer flow channel is located inside the valve core 20, the inner layer flow channel is arranged inside the valve core 20, the space occupied by the valve core 20 is fully utilized, and on the basis that the first communicating channel 211 is arranged on the outer peripheral wall of the valve core 20, the number of selectable modes is further increased, so that more working requirements are met.

Meanwhile, the inner-layer flow channel of the second communication channel 212 is arranged inside the valve core 20, which can satisfy the communication between the two circulation through holes 11 under complex conditions, for example, the two circulation through holes 11 on the diagonal line are directly communicated through the first communication channel 211 on the outer peripheral wall of the valve core 20, which must affect the communication between the two circulation through holes 11 on the two sides of the diagonal line, and by arranging the inner-layer flow channel inside the valve core 20, such a problem can be avoided, and the design difficulty of the valve core 20 is reduced.

The number of the communication ports may be two or more, so that the space occupied by the valve core 20 is fully utilized, and the machining and forming manner of the second communication channel 212 is simple and reliable. It should be noted that, when the number of the communication ports on the peripheral wall of the valve core 20 is three or more, any two communication ports may define one second communication channel 212 with the inner-layer flow channel, that is, the number of the second communication channels 212 is two or more, so that the switching modes of the multi-channel switching valve 100 may be increased, thereby satisfying more working requirements.

Preferably, the two communication ports are located on the outer peripheral wall of the valve core 20, the inner flow passage is located inside the valve core 20, and by arranging the inner flow passage inside the valve core 20, the space occupied by the valve core 20 can be fully utilized, and on the basis that the first communication passage 211 is arranged on the outer peripheral wall of the valve core 20, the number of selectable modes is further increased, so that more working requirements are met.

When the multi-channel switching valve 100 is closed, i.e. the through-flow hole 11 is not communicated with the switching channel 21, the multi-channel switching valve 100 is in a closed state. When the multi-channel switching valve 100 is operated, the actuator device 40 drives the valve element 20 to rotate, and when the valve element 20 rotates by a certain angle, the switching channel 21 and the flow through hole 11 start to be communicated, the valve element 20 continues to rotate, the communication area of the switching channel 21 and the flow through hole 11 gradually increases, and the flow rate which can pass through the valve element also increases.
