[0038] The following describes a filtering mechanism and a method of use of a flow control valve according to an embodiment of the present application with reference to the accompanying drawings.

[0039] like Figure 1-Figure 10As shown, a filtering mechanism of a flow regulating valve according to an embodiment of the present application includes a filter tube 1 connected to a flow regulating valve pipeline, a filter cartridge 7 is rotatably installed on the inner side of the filter tube 1, a filter plate 11 is provided at one end of the filter cartridge 7, and the filter plate 11 seals one end of the filter cartridge 7. The medium entering the filter tube 1 needs to be filtered through the filter cartridge 7 and the filter plate 11, and impurities in the medium are retained in the filter cartridge 7, which not only improves the purity of the medium and extends the service life of the flow regulating valve, but also facilitates the recovery of impurities.

[0040] Among them, a sealing sleeve 12 is arranged on the outer side of the inlet end of the filter cartridge 7, and the sealing sleeve 12 seals the inlet of the filter tube 1 so that the medium can only enter the filter cartridge 7. At the same time, a swivel 15 is arranged on one side of the sealing sleeve 12. The swivel 15 is rotatably connected to the swivel groove 3 opened at the inlet end of the filter tube 1. The swivel 15 is located in the swivel groove 3, which improves the sealing performance of the connection between the sealing sleeve 12 and the filter tube 1 and prevents the medium from overflowing.

[0041] In addition, slide rails 4 are symmetrically installed on the outside of the filter tube 1, and an extension tube 16 is connected to the other end of the filter tube 1. Two connecting rods 18 arranged on the outside of the extension tube 16 are slidably connected to the two slide rails 4 respectively. The extension tube 16 blocks the filter cartridge 7 so that the filter cartridge 7 is located on the inside for use. At the same time, a rotating groove 14 is opened on the other side of the sealing sleeve 12, and a rotating ring 19 is arranged on the inner side of the extension tube 16. The rotating ring 19 is rotatably connected to the rotating groove 14, thereby ensuring the sealing between the sealing sleeve 12 and the extension tube 16.

[0042] Furthermore, a fixing plate 17 is provided on the outside of the extension tube 16 , and the size of the fixing plate 17 matches the size of the fixing sleeve 2 . When the extension tube 16 is located on one side of the filter tube 1 , the fixing plate 17 is attached to one side of the fixing sleeve 2 to seal the fixing sleeve 2 .

[0043] In order to make the filter cartridge 7 rotate automatically, a gear ring 13 is provided on the outside of the sealing sleeve 12, and a fixed sleeve 2 is provided on the outside of the filter tube 1. The fixed sleeve 2 is a circular structure with a hollow interior. A driving wheel 6 is rotatably provided on the inner side of the fixed sleeve 2. When the motor drives the driving wheel 6, the driving wheel 6 rotates. Combined with the meshing of the driving wheel 6 and the gear ring 13, the gear ring 13 rotates with the filter cartridge 7 and the filter plate 11.

[0044] like Figure 1 As shown, a screw rod 5 is rotatably arranged in one of the slide rails 4, and the screw rod 5 is threadedly connected to the connecting rod 18. The connecting rod 18 can be moved by the rotation of the screw rod 5. At the same time, the use of the screw rod 5 improves the stability of the extension tube 16 and ensures the stability of the gear ring 13 when rotating with the filter cartridge 7.

[0045] In order to improve the filtering effect, a cleaning mechanism is installed inside the extension tube 16. When the cleaning mechanism is located inside the filter cartridge 7, it cleans the filter cartridge 7. Specifically, the cleaning mechanism includes a diverter 20 located in the extension tube 16. The diverter 20 can be used to divert the medium. At the same time, a fixing rod 21 is arranged at the center of the diverter 20. A symmetrical support rod 22 is arranged on the upper side of the fixing rod 21. A brush 23 is connected to the upper end of the support rod 22. When the brush 23 is located inside the filter cartridge 7, it fits with the inner wall of the filter cartridge 7. When the filter cartridge 7 rotates, the brush 23 cleans the inner wall of the filter cartridge 7.

[0046] When the filter cartridge 7 and filter plate 11 need to be replaced or deeply cleaned, refer to Figure 2 , the connecting rod 18 can be moved outward with the extension tube 16 by rotating the screw rod 5, so that the extension tube 16 is away from the filter tube 1. Since the other end of the fixing rod 21 is rotatably connected to the filter plate 11, the sealing sleeve 12, the filter cartridge 7 and the filter plate 11 can be moved out of the filter tube 1 by the driving of the fixing rod 21. At this time, the filter cartridge 7 and the filter plate 11 can be replaced or cleaned.

[0047] In addition, by pushing the sealing plate 10 outward, the sealing plate 10 on the outside of the filter cartridge 7 can be moved out of the clamping groove 9 to expose the impurity discharge port 8, so that the impurities in the filter cartridge 7 can be discharged.

[0048] On the other hand, the present invention also provides a method for using the filter mechanism of the flow control valve, and the operating steps are as follows:

[0049] S1, using a motor to drive the driving wheel 6, so that the driving wheel 6 meshes with the gear ring 13, and then the gear ring 13 rotates with the filter cartridge 7 and the filter plate 11 to filter the medium passing through the filter tube 1;

[0050] When the filter cartridge 7 rotates in steps S2 and S1, the inner wall of the filter cartridge 7 is in contact with the brush 23, and the brush 23 cleans the inner wall of the filter cartridge 7;

[0051] S3, when it is necessary to perform deep cleaning on the filter cartridge 7 cleaned in step S2, the screw rod 5 installed in one of the slide rails 4 is rotated, and the screw rod 5 is threadedly connected with the connecting rod 18, so that the connecting rod 18 and the extension tube 16 are moved away from the filter tube 1, and at the same time, the filter cartridge 7 and the filter plate 11 are moved out of the filter tube 1 together with the driving of the fixing rod 21, so as to achieve deep cleaning of the filter cartridge 7;

[0052] S4. After cleaning the filter cartridge 7 in step S3, the sealing plate 10 installed in the impurity discharge port 8 can be pushed to slide the sealing plate 10 to one end of the impurity discharge port 8 and expose the impurity discharge port 8, so as to facilitate the discharge of impurities in the filter cartridge 7 from the impurity discharge port 8.

[0053] A filtering mechanism of a flow regulating valve and a working process of a method for using the same are as follows: a driving wheel 6 is driven by a motor to mesh the driving wheel 6 with a gear ring 13, the gear ring 13 rotates with the filter cartridge 7 and the filter plate 11, and the filter cartridge 7 and the filter plate 11 are used to filter the medium entering the filter tube 1. At the same time, when the filter cartridge 7 and the filter plate 11 rotate, the inner wall of the filter cartridge 7 is cleaned by a brush 23 to improve the filtering effect of the filter cartridge 7, and when the screw rod 5 rotates, the connecting rod 18 can move outward with the extension tube 16, and driven by the fixing rod 21, the filter cartridge 7 and the filter plate 11 are moved out of the filter tube 1, thereby facilitating the replacement or deeper cleaning of the filter cartridge 7 and the filter plate 11, and eliminating the use of a large number of screws, so that the device can be quickly disassembled and assembled, saving the time for disassembly and assembly.

It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0055] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
