[0020] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0021] Reference Figures 1-3, what is disclosed in the embodiments of the present utility model is: a valve composite filtering structure, including a valve body 1, a water inlet channel 2 and a water outlet channel 3 opened in the valve body 1. A connecting pipe 4 is obliquely arranged on the valve body 1, and the connecting pipe 4 is communicated with the water inlet channel 2. A filter cylinder 6 is inserted into the connecting pipe 4, and one end of the filter cylinder 6 abuts against the inner wall of the water inlet channel 2. An avoidance opening for water flow to pass through is opened at the front end of the filter cylinder 6, and the rear end is used for filtering water flow. A sealing block 5 is arranged at the other end of the filter cylinder 6. The sealing block 5 is arranged on the connecting pipe 4 through a threaded connection to seal the connecting pipe 4. A sealing gasket 16 is arranged between the sealing block 5 and the connecting pipe 4. A sealing channel 17 is circumferentially opened on the connecting pipe 4. The sealing gasket 16 is arranged in the sealing channel 17. A compression spring 18 is arranged between the sealing gasket 16 and the sealing channel 17. The sealing gasket 16 abuts against the sealing block 5. A cleaning device for cleaning the filter cylinder 6 is arranged on the connecting block 12.

[0022] Specifically, the cleaning device includes a reciprocating lead screw 7. The reciprocating lead screw 7 is rotatably inserted into the sealing block 5. A reciprocating block 8 is arranged on the reciprocating lead screw 7. A brush 9 is arranged on the reciprocating block 8. The brush 9 abuts against the inner wall of the filter cylinder 6. A driving motor for driving the reciprocating lead screw 7 to rotate is arranged on the sealing block 5. Among them, when in use, the filter cylinder 6 can filter impurities in the water flow, thereby preventing impurities from adhering to the valve plate, preventing the valve plate from being rusted and worn by impurities, thereby improving the service life of the valve plate, and further improving the service life of the valve. Moreover, impurities will not accumulate and block the inside of the valve, so as not to affect the valve's conveyance of fluid medium. When impurities adhere to the filter cylinder 6, the driving motor rotates to drive the reciprocating lead screw 7 to rotate, and the reciprocating lead screw 7 drives the reciprocating block 8 to slide, so that the brush 9 brushes the filter cylinder 6 back and forth, thereby brushing off the impurities on the surface, thereby improving the filtering capacity of the filter cylinder 6. At the same time, the staff can remove the sealing block 5 and then clean out the internal impurities. When the sealing block 5 abuts against the connecting pipe 4, the sealing block 5 presses the sealing gasket 16, thereby compressing the compression spring 18. The compression spring 18 releases elastic force, so that the sealing gasket 16 tightly abuts against the sealing block 5, thereby improving the sealing performance between the sealing block 5 and the connecting pipe 4.

[0023] In order to facilitate the replacement of the brush 9, it further includes a connecting rod 11, an anti-detachment rod 13, and a sliding block 14. One end of the connecting rod 11 is fixedly arranged on the brush 9, and the other end of the connecting rod 11 passes through the reciprocating block 8. The connecting rod 11 is provided with an anti-detachment channel. A connecting block 12 is arranged on the reciprocating block 8, and the connecting block 12 is provided with a first channel. The anti-detachment rod 13 passes through the first channel and is arranged in the anti-detachment channel. The other end of the anti-detachment rod 13 passes out of the connecting block 12. The sliding block 14 is arranged on the anti-detachment rod 13. A spring 15 is sleeved on the anti-detachment rod 13. One end of the spring 15 abuts against the sliding block 14, and the other end of the spring 15 abuts against the inner wall of the first channel. Among them, when the brush 9 needs to be replaced, the anti-detachment rod 13 is pulled to release the engagement between the anti-detachment rod 13 and the anti-detachment channel, so that the brush 9 can be removed. Then, the connecting rod 11 of the new brush 9 is inserted into the reciprocating block 8, and then the anti-detachment rod 13 is engaged with the anti-detachment channel. It is simple and convenient, which is beneficial for the staff to replace the brush 9.

[0024] In order to prevent the reciprocating block 8 from sliding out of the reciprocating lead screw 7, a limiting block 10 is arranged at the end of the reciprocating lead screw 7, and the reciprocating block 8 abuts against the limiting block 10 after sliding.
