DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Embodiment 1 See also Figure 1-Figure 10 The present invention provides a technical solution: a hydraulic control valve with a filter, comprising an input body 1 and an output body 2, wherein the input body 1 and the output body 2 form a valve body, a valve plate 3 is arranged in the valve body, a valve stem 4 is connected to the top of the valve plate 3, and the valve stem 4 extends out of the valve body, and a filter mechanism 5 is connected to the input end of the output body 2; The filtering mechanism 5 includes a connecting tube body 501, which is connected to the input end of the output body 2. A filter screen 505 is fixedly installed inside the connecting tube body 501. There are three filter screens 505, and the filtering accuracy of the filter screen 505 gradually increases from the input end. The center of the filter screen 505 is rotatably connected to a rotating shaft 1 507 through a bearing. A rotating cleaning component 506 is fixedly installed on the outer wall of the rotating shaft 1 507. There are three rotating cleaning components 506, which correspond to the three filter screens 505 one by one. A recovery component 503 is arranged in the connecting tube body 501. The rotating shaft 1 507 is connected to the rotating shaft 2 508 through a helical gear set. The second rotating shaft 508 extends out from the connecting pipe body 501 through the sealing shaft 509. The second rotating shaft 508 is connected to the driving component 504. The filtering accuracy is gradually improved from the outside to the inside, and it can effectively intercept impurities of different particle sizes. The outermost layer can intercept larger water plants, garbage, etc., the middle layer intercepts medium-sized sediment particles, and the innermost layer can intercept fine impurity particles to ensure the cleanliness of the water flow entering the valve core. The driving component 504 is used to drive the second rotating shaft 508 to rotate, thereby driving the first rotating shaft 507 to rotate. The rotation of the first rotating shaft 507 drives the rotating cleaning component 506 to rotate, and the surface of the filter screen 505 is cleaned. The impurities are collected by the recovery component 503. The recycling component 503 includes a recycling bin 5031, a mounting plate 5032, a blocking plate 5033, and a through hole 5035. The recycling bin 5031 is provided in the connecting pipe body 501, and the through hole 5035 is provided on the mounting frame 502. The through hole 5035 is communicated with the recycling bin 5031. There are three recycling bins 5031 and three through holes 5035, and they correspond to the three filter screens 505 one by one. The mounting plate 5032 is fixedly connected to the bottom of the connecting pipe body 501 by screws. The blocking plate 5033 is fixedly installed on the top of the mounting plate 5032. The blocking plate 5033 is inserted into the bottom opening of the recycling bin 5031. The recycling bin 5031 corresponds to the filter screens 505 one by one. The bin 5031 collects the impurities cleaned by the rotating cleaning component 506, that is, after the impurities are cleaned from the filter 505, they will be impacted by the newly entered water flow and then washed into the recovery bin 5031. The mounting plate 5032 and the blocking plate 5033 are provided to block the opening at the bottom of the recovery bin 5031. When cleaning is required, the mounting plate 5032 and the blocking plate 5033 need only be removed, or when sewage needs to be discharged, the bottom opening of the recovery bin 5031 is always opened, so that the water flow that can pass through the filter 505 can pass through, and the other part of the water flow can carry the impurities into the recovery bin 5031 and then be discharged, thereby avoiding a large amount of impurities from accumulating in the mounting frame 502; The inner diameter of the through hole 5035 is smaller than the inner diameter of the top opening of the recovery bin 5031, so that impurities are impacted into the recovery bin 5031 by the water flow, and will not be easily brought into the mounting frame 502 by the backflow of water. The outer wall of the blocking plate 5033 is fixedly sleeved with a sealing ring 5034, which is inserted into the bottom opening of the recovery bin 5031 to ensure the sealing effect when the mounting plate 5032 and the blocking plate 5033 block the opening of the recovery bin 5031. The rotating cleaning component 506 includes a rotating frame 5061, which is fixedly sleeved on the rotating shaft 1 507. A cleaning brush 5062 and a scraper 5063 are fixedly installed on the outer wall of the rotating frame 5061 facing the nearest filter 505. The cleaning brush 5062 contacts the outer wall of the filter 505, and a gap is left between the scraper 5063 and the filter 505. The scraper 5063 is used to break larger impurities so that the larger impurities can also enter the recovery bin 5031. The cleaning brush 5062 is used to brush off the impurities adsorbed on the filter 505. The inner wall of the connecting tube body 501 is fixedly mounted with a sealing ring 6, which blocks the end of the mounting frame 502 to ensure the sealing effect of the connection between the mounting frame 502 and the connecting tube body 501 to prevent water leakage; A waterproof cover 13 is provided at the transmission connection between the rotating shaft 1 507 and the rotating shaft 2 508. The waterproof cover 13 covers the helical gear set connecting the rotating shaft 1 507 and the rotating shaft 2 508 to reduce the erosion of the helical gear set by water flow. Two sealing shafts 509 are provided at the rotating shaft 2 508 passing through the connecting pipe body 501 and the mounting frame 502. A water-proof filler 7 is filled between the two sealing shafts 509 to further improve the waterproof effect between the rotating shaft 2 508 and the connecting pipe body 501 and the mounting frame 502, and prevent water flow from flowing out of the gap between the rotating shaft 2 508 and the connecting pipe body 501 and the mounting frame 502. A mounting seat 9 is fixedly installed on the top of the input body 1, and the valve stem 4 extends from the mounting seat 9. A detachable handle 10 is sleeved on the top of the valve stem 4. A limiting bolt is fixedly installed on the top of the mounting seat 9. A calibration plate 12 is fixedly sleeved on the outer wall of the valve stem 4. The calibration plate 12 and the limiting bolt on the top of the mounting seat 9 are located on the same plane. A connecting rod 11 is fixedly installed on the top of the calibration plate 12, and the top of the connecting rod 11 is inserted into the detachable handle 10. The detachable handle 10 that can be removed from the valve stem 4 is used to rotate the valve stem 4 to realize the opening and closing of the control valve. The rotation angle of the calibration plate 12 is limited by the limiting bolt on the mounting seat 9, and the user is prompted at the same time whether the control valve has reached the maximum opening and closing degree. The detachable handle 10 and the calibration plate 12 are connected by the connecting rod 11, so that the calibration plate 12 can be driven to rotate synchronously when the detachable handle 10 is rotated.

[0019] Working principle: When in use, water flows in from the mounting frame 502, and then passes through the three filter screens 505 in sequence. The outermost layer can intercept larger aquatic plants, garbage, etc., the middle layer intercepts medium-sized sediment particles, and the innermost layer can intercept fine impurity particles. When the water flow rate is large, the mounting plate 5032 and the blocking plate 5033 can be removed, and the impurities intercepted by the filter screen 505 can be brought into the recovery bin 5031 by a part of the water flow, and then discharged from the bottom opening of the recovery bin 5031. At the same time, the driving component 504 drives the rotating shaft 2 508 to rotate, and then drives the rotating shaft 1 507 to rotate. The rotation of the rotating shaft 1 507 drives the rotating cleaning component 506 to rotate, and the surface of the filter screen 505 is cleaned. The cleaned impurities are brought into the recovery bin 5031 by the water flow, and then discharged.
