[0067] Furthermore, through the cooperation of the gas storage cavity 49 and the sealing plate 50 , the excess gas squeezed out of the fifth airbag 46 is stored.

[0068] Example 3: Figure 4-Figure 7 As shown, the structure of the hydraulic control valve disclosed in the third embodiment of the present invention is basically the same as that in the second embodiment, except that:

[0069] The center of the filter plate 3 is rotatably connected to a rotating shaft 21, one end of a fixed rod 20 is connected to the rotating shaft 21, and multiple groups of fixed rods 20 are provided, and the multiple groups of fixed rods 20 are distributed in a circle with the rotating shaft 21 as the center;

[0070] A transmission gear 23 is mounted at the center of one end of the rotating shaft 21 away from the filter plate 3. A transmission rod 16 is provided on one side of the transmission gear 23. The transmission rod 16 has a plurality of sets of spaced teeth 22 formed on one side of the transmission gear 23. The teeth 22 and the transmission gear 23 are meshed with each other.

[0071] The fixed rod 20 rotates through the cooperation of the rotating shaft 21, the transmission gear 23 and the transmission rod 16;

[0072] A second receiving groove 14 is defined at the top end of the valve body 1, corresponding to the end of the transmission rod 16. The top end of the transmission rod 16 is inserted into the second receiving groove 14. A guide groove 17 is defined on the inner sidewall of the second receiving groove 14. A guide block 18 is slidably disposed within the guide groove 17. A first return spring 19 is disposed between the lower end surface of the guide block 18 and the inner bottom end of the guide groove 17.

[0073] A second air bag 15 is provided between the top end of the transmission rod 16 and the inner top end of the second receiving groove 14;

[0074] A first receiving groove 11 is defined at the top of the water inlet end of the valve body 1, away from the filter plate 3. A trigger block 10 is disposed within the first receiving groove 11. A first airbag 12 is disposed between the upper end surface of the trigger block 10 and the top of the first receiving groove 11. A first exhaust pipe 13 is defined between the first airbag 12 and the second airbag 15. The first airbag 12 communicates with the second airbag 15 through the first exhaust pipe 13.

[0075] A third receiving groove 28 is formed on the lower end surface of each fixing rod 20. A scraper 30 is provided inside each third receiving groove 28. A second return spring 29 is provided on the upper end surface of the scraper 30 and the top end of the inner portion of the third receiving groove 28. The scraper 30 is in elastic contact with the side wall of the filter plate 3 via the second return spring 29.

[0076] The water entering the valve body 1 is filtered through the filter plate 3. When impurities in the water clog the filter plate 3, the filtering efficiency of the filter plate 3 is reduced. At this time, the water pressure at the water inlet end of the valve body 1 increases, and the water pressure pushes the trigger block 10 upward. When the trigger block 10 is pushed, the first airbag 12 is squeezed, and the gas inside the first airbag 12 is discharged to the inside of the second airbag 15 through the first exhaust pipe 13. The second airbag 15 expands and pushes the transmission rod 16 downward. When the transmission rod 16 moves downward, the transmission gear 23 cooperates to drive the rotating shaft 21 and the multiple groups of fixed rods 20 connected to the rotating shaft 21 to rotate. During the rotation process, the fixed rod 20 drives the elastically connected scraper 30 to clean the impurities adhering to the surface of the filter plate 3.

[0077] Example 4: Figure 4-Figure 7 As shown, the structure of the hydraulic control valve disclosed in the third embodiment of the present invention is basically the same as that in the second embodiment, except that:

[0078] A collection box 24 is installed on one side wall of each fixing rod 20, and the collection box 24 rotates along the side wall of the filter plate 3 through the fixing rod 20;

[0079] A side wall of the fixing rod 20 close to the collecting box 24 is provided with an oblique cut surface 31 , and a through slot 34 is provided on the lower end surface of the collecting box 24 at a position corresponding to the oblique cut surface 31 ;

[0080] A plurality of groups of filter holes 33 are formed in the collecting box 24 at one end away from the through slot 34.

[0081] A collection box 24 is installed on one side wall of each fixing rod 20, and the collection box 24 rotates along the side wall of the filter plate 3 through the fixing rod 20;

[0082] A side wall of the fixing rod 20 close to the collecting box 24 is provided with an oblique cut surface 31 , and a through slot 34 is provided on the lower end surface of the collecting box 24 at a position corresponding to the oblique cut surface 31 ;

[0083] A plurality of groups of filter holes 33 are formed in the collecting box 24 at one end away from the through slot 34.

[0084] A fourth receiving groove 36 is defined in the sidewall of the through groove 34. A shield plate 35 is disposed within the fourth receiving groove 36. A third return spring 37 is disposed between the end of the shield plate 35 and the inner sidewall of the fourth receiving groove 36. The shield plate 35 is elastically disposed within the fourth receiving groove 36 by the third return spring 37.

[0085] A limiting groove 43 is formed on the lower end surface of the fourth receiving groove 36 . A limiting block 44 is slidably provided inside the limiting groove 43 . The limiting block 44 is connected to the shielding plate 35 .

[0086] A fifth receiving slot 38 is defined on the lower end surface of the collection box 24 at a position corresponding to the shield 35. A shock rod 39 is inserted into the interior of the fifth receiving slot 38. A fourth return spring 41 is disposed between the upper end surface of the shock rod 39 and the inner top end of the fifth receiving slot 38. The shock rod 39 is elastically connected to the collection box 24 via the fourth return spring 41.

[0087] The side walls of the filter plate 3 are provided with arcuate grooves 32 at positions corresponding to the ends of the shock rods 39. The arcuate grooves 32 are provided in multiple groups, and the multiple groups of arcuate grooves 32 are distributed circumferentially. The side walls on both sides of the ends of the shock rods 39 at positions corresponding to the arcuate grooves 32 are all beveled.

[0088] A third airbag 40 is disposed between the top end of the shock rod 39 and the inner top end of the fifth receiving groove 38. A fourth airbag 45 is disposed between the side wall of the limit block 44 and the side wall of the limit groove 43. A second exhaust duct 42 is provided between the fourth airbag 45 and the third airbag 40. The third airbag 40 is connected to the fourth airbag 45 through the second exhaust duct 42.

[0089] When the fixed rod 20 drives the scraper 30 to rotate, a certain amount of impurities will accumulate on one side of the scraper 30 and be collected into the collection box 24 through the cooperation of the beveled surface 31 and the through groove 34. When the elastically arranged shock rod 39 moves below the arc-shaped groove 32, the top of the shock rod 39 will no longer squeeze the third airbag 40, and the gas inside the fourth airbag 45 will be discharged through the support of the third return spring 37. After the shield 35 extends from the inside of the fourth receiving groove 36, it blocks the through groove 34, preventing the impurities inside the collection box 24 from being discharged.

[0090] When the collecting box 24 drives the shock rod 39 to rotate, it will be continuously inserted into the interior of the arc groove 32 and then rotated out, so that the shock rod 39 continuously shocks the filter plate 3, shaking off the impurities stuck in the filter holes on the filter plate 3.

[0091] The specific solution is as follows: through the cooperation of the opening and closing device 2 and the connecting rod 8, the rotation of the valve core 9 is controlled, thereby controlling the opening and closing of the valve body 1. When the valve body 1 is opened, the filter plate 3 is used for filtering.

[0092] When impurities in the water clog the filter plate 3, the filtration efficiency of the filter plate 3 decreases. At this time, the water pressure at the water inlet end of the valve body 1 increases, and the water pressure pushes the trigger block 10 upward. When the trigger block 10 is pushed, the first airbag 12 is squeezed, and the gas inside the first airbag 12 is discharged into the second airbag 15 through the first exhaust pipe 13. The second airbag 15 expands and pushes the transmission rod 16 downward. When the transmission rod 16 moves downward, the transmission gear 23 cooperates to drive the rotating shaft 21 and the multiple groups of fixed rods 20 connected to the rotating shaft 21 to rotate. During the rotation process, the fixed rod 20 drives the elastically connected scraper 30 to clean the impurities adhering to the surface of the filter plate 3;

[0093] When the fixed rod 20 drives the scraper 30 to rotate, a certain amount of impurities will accumulate on one side of the scraper 30 and be collected into the collection box 24 through the cooperation of the beveled surface 31 and the through groove 34. When the elastically arranged shock rod 39 moves below the arc-shaped groove 32, the top of the shock rod 39 will no longer squeeze the third airbag 40, and the gas inside the fourth airbag 45 will be discharged through the support of the third return spring 37. After the shield 35 extends from the inside of the fourth receiving groove 36, it blocks the through groove 34, preventing the impurities inside the collection box 24 from being discharged.

[0094] When cleaning the impurities inside the collecting box 24 , this can be achieved by removing the arc-shaped fixing plate 5 .

[0095] The present invention is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
