[0053] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In the description of this application, it should be noted that the terminology used herein is only for describing specific implementations and is not intended to limit the exemplary implementations according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings indicate similar items, and therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings. Example 1

[0054] This embodiment provides a multi-way switching valve, including:

[0055] Valve body 1, which has an inlet pipe 2;

[0056] The liquid outlet pipe 3 has several of them. Several liquid outlet pipes 3 are fixedly installed on the outer surface of the valve body 1. The liquid inlet 4 of several liquid outlet pipes 3 and the liquid outlet 5 of the liquid inlet pipe 2 are all opened on the upper end face of the valve body 1.

[0057] The movable disc 6 is located above the valve body 1, and the lower end face of the movable disc 6 is in contact with the valve body 1;

[0058] The connecting groove 7 is located below the moving disc 6 and is used to connect the liquid outlet 5 of the liquid inlet pipe 2 to the liquid inlet 4 of one of the liquid outlet pipes 3.

[0059] A clamping assembly, which is mounted on the valve body 1, is used to clamp the moving disc 6;

[0060] A drive assembly, which is mounted on the valve body 1, is used to drive the moving disc 6 to rotate;

[0061] When the moving disc 6 rotates, the connecting groove 7 connects the liquid outlet 5 of the liquid inlet pipe 2 with the liquid inlet 4 of different liquid outlet pipes 3.

[0062] In this technical solution, there are several outlet pipes 3. In actual use, the inlet pipe 2 is the main line, and the several outlet pipes 3 are several branch lines. When the liquid is transported into the valve body 1 from the main line, the liquid will pass through the inlet pipe 2 and then be discharged from the outlet 5 of the inlet pipe 2. The moving disc 6 is pressed against the upper end of the valve body 1 by the clamping assembly, and at the same time rotated by the drive assembly.

[0063] The moving disc 6 has a connecting groove 7. Liquid enters the connecting groove 7 after passing through the inlet pipe 2 and being discharged from the outlet 5 of the inlet pipe 2. Since the outlet 5 of the inlet pipe 2 is connected to the inlet 4 of one of the outlet pipes 3 through the connecting groove 7, the liquid entering the connecting groove 7 will flow out from the outlet pipe 3 corresponding to the current position due to water pressure, forming the connection between the main path and the corresponding branch path.

[0064] When the outlet 5 of the inlet pipe 2 is connected to the inlet 4 of one of the outlet pipes 3 through the connecting groove 7, the lower end face of the passive disc 6 of the inlet 4 of the other outlet pipes 3 is blocked, and the pipes are in a blocked state.

[0065] When it is necessary to switch branches, simply rotate the disc 6 so that the outlet 5 of the inlet pipe 2 is connected to the inlet 4 of the other outlet pipes 3 through the connecting groove 7, and then liquid can be input from the inlet pipe 2.

[0066] With this structural design, an inlet 4 and several outlets 5 are set on the valve body 1, and the connection between the main road and different branches is switched through the moving disc 6 and the connecting groove, which facilitates feeding materials to different branches through the main road. At the same time, the whole is integrated into a valve body 1, which reduces maintenance costs and increases economic benefits. Example 2

[0067] This embodiment provides a multi-way switching valve, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0068] Furthermore, it also includes:

[0069] A stationary disc 8 is disposed between the moving disc 6 and the valve body 1. The stationary disc 8 has through holes 9 corresponding to the liquid outlet 5 and the liquid inlet 4.

[0070] Sealing groove 10, the upper end face of the valve body 1 and the lower end face of the stationary disc 8 are both provided with sealing groove 10;

[0071] The sealing ring 11 is located in the sealing groove 10 and is used to seal the liquid outlet 5, the liquid inlet 4 and the through hole 9.

[0072] The lower end face of the moving disc 6 abuts against the upper end face of the stationary disc 8. When the moving disc 6 rotates, one end of the connecting groove 7 rotates around the liquid outlet 5 of the liquid inlet pipe 2 as the axis, and the other end of the connecting groove 7 is connected to the through hole 9 corresponding to the liquid inlet 4 of different liquid outlet pipes 3.

[0073] In this technical solution, the stationary disc 8 and the valve body 1 are sealed by the sealing groove 10 and the sealing ring 11, so that the holes on the valve body 1 and the stationary disc 8 correspond to each other, and the holes are sealed by the sealing ring 11, so that cross-flow contamination will not occur between the holes.

[0074] Since the moving disc 6 needs to rotate to switch the connection between the main circuit and different branch circuits, the valve body 1 will inevitably experience some wear after long-term use, resulting in leakage. By setting a stationary disc 8, the stationary disc 8 is in contact with the moving disc 6, so that even if wear occurs, either the stationary disc 8 or the moving disc 6 can be replaced separately, reducing the overall maintenance cost.

[0075] While the clamping assembly clamps the moving disk 6, it also clamps the stationary disk 8 through the transmission of force to prevent leakage.

[0076] The stationary disc 8 is positioned on the valve body 1 through the cooperation of the sealing groove 10 and the sealing ring 11, so as to prevent the stationary disc 8 from rotating when the moving disc 6 rotates, thus affecting the transmission effect.

[0077] This structural design, by incorporating a stationary disc 8, a sealing groove 10, and a sealing ring 11, reduces cross-flow contamination between pipelines and lowers maintenance costs, thus enhancing the economic benefits of this invention. Example 3

[0078] This embodiment provides a multi-way switching valve, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0079] Furthermore, the positioning component includes:

[0080] Positioning block 12 is fixedly installed on the upper end of valve body 1, and at least two positioning blocks 12 are provided;

[0081] The positioning groove 13 is formed through the stationary disc 8 and corresponds to the positioning block 12, which is located inside the positioning groove 13.

[0082] This structural design allows the stationary disc 8 to be positioned on the valve body 1 through the cooperation of the positioning block 12 and the positioning groove 13. It is then pressed together with the moving disc 6 and the valve body 1 by the clamping assembly, resulting in better overall stability and less wobbling. It also completely eliminates the possibility of the moving disc 6 causing the stationary disc 8 to deflect. Example 4

[0083] This embodiment provides a multi-way switching valve, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0084] Furthermore, the driving component includes:

[0085] The drive disk 14 has several claws 19 at its lower end, and the drive disk 14 is positioned above the moving disk 6;

[0086] The card slot 15 is located above the moving disk 6, and the claw 19 of the drive disk 14 is located in the card slot 15 of the moving disk 6.

[0087] The drive rod 16 is fixedly mounted on the upper end of the drive disk 14 and is used to rotate the drive disk 14.

[0088] In this technical solution, the drive disk 14 is pressed by the pressing assembly, so that the pressing assembly provides a pressing force towards the valve body 1 to the drive disk 14, the moving disc 6, and the stationary disc 8 from top to bottom.

[0089] Meanwhile, by designing the cooperation between the claw 19 and the slot 15, when the drive disk 14 rotates, the claw 19 and the slot 15 can drive the disk 6 to rotate.

[0090] By designing the drive rod 16, a drive motor or other components for driving rotation (this is existing technology and will not be described in detail here) can be set on the outside and connected to the drive rod 16 to drive the drive rod 16 to rotate, thereby causing the drive disk 14 to drive the moving disc 6 to rotate, and thus the connection between different branches and the main road is realized through the rotation of the moving disc 6.

[0091] Through this structural design, the drive component is set up to facilitate the rotation of the moving disc 6, thereby completing the opening and closing between each branch and the main circuit. At the same time, the cooperation between the claw 19 and the slot 15 prevents slippage between the drive disk 14 and the moving disc 6. Furthermore, the drive rod 16 is set up to facilitate the connection of an external drive motor or other components for driving rotation to the drive rod 16 to drive the drive rod 16 to rotate. Example 5

[0092] This embodiment provides a multi-way switching valve, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0093] Furthermore, it also includes:

[0094] The housing 17 has its lower end detachably connected to the valve body 1, and the upper end of the drive rod 16 protrudes out of the housing 17.

[0095] The housing 17 encloses the stationary disc 8, the moving disc 6, and the drive disk 14.

[0096] This structural design, with the inclusion of a housing 17, protects the stationary disc 8, the moving disc 6, and the drive disk 14, preventing foreign objects from impacting or entering and improving stability.

[0097] The inner diameter of the housing matches the outer diameter of the moving and stationary discs. Example 6

[0098] This embodiment provides a multi-way switching valve, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0099] Furthermore, it also includes:

[0100] Spring 18 is sleeved on drive rod 16. The lower end of spring 18 abuts against moving disc 6, and the upper end of spring 18 abuts against the inner side of housing 17.

[0101] In this technical solution, the spring 18 provides pressure to the moving disc 6, so that the moving disc 6 can press against the stationary disc 8 and the valve body 1, preventing leakage of the valve body 1, and at the same time not affecting the rotation of the moving disc 6, making it more convenient to use. At the same time, the setting of the spring 18 also makes the overall cost of the parts lower and facilitates the replacement of parts. Example 7

[0102] This embodiment provides a multi-way switching valve, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0103] Furthermore, the inlet pipe 2 is equipped with a one-way valve.

[0104] In this technical solution, a one-way valve is installed to prevent backflow and avoid pipeline contamination. Example 8

[0105] This embodiment provides a multi-way switching valve, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0106] Furthermore, the valve body 1, the stationary disc 8, and the moving disc 6 are all made of PTFE plastic.

[0107] In this technical solution, in the field of industrial washing machines, the liquids transported are mostly highly corrosive liquids, and the metal parts such as the spring 18 and valve core inside the valve body 1 are easily corroded and damaged.

[0108] This structural design, by using PTFE plastic for the valve body 1, stationary disc 8, and moving disc 6, greatly enhances the corrosion resistance of the overall structure and extends its service life. Example 9

[0109] This embodiment provides a multi-way switching valve, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0110] Furthermore, it also includes:

[0111] Boss 20, the lower end of the moving disc 6 protrudes to form a circular boss;

[0112] A circular groove 21 is located at the top of the stationary disc 8;
