Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic valves, in particular to a hydraulic valve with a self-cleaning function. Background Art

[0002] Hydraulic valves, used in hydraulic systems to limit pressure, flow, and change the direction of fluid flow, typically consist of a valve body, a valve core, and control components, most often also equipped with a spring. During operation, hydraulic valves are subject to multiple forces, including hydraulic pressure, spring force, and mechanical or manual forces. They obey the principle of force balance and move only under the influence of these forces. If all forces are balanced, they remain stationary.

[0003] Various liquids often flow through the inside of the hydraulic valve, but the liquids often contain some solid impurities. When the solid impurities pass through the hydraulic valve, the solid impurities in the liquid will accelerate the damage of the metal. If they remain inside the hydraulic valve, they will corrode the inside of the hydraulic valve. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a hydraulic valve with a self-cleaning function.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A hydraulic valve with a self-cleaning function, comprising:

[0007] Hydraulic valve body;

[0008] The self-cleaning component also includes a filter frame, a slide groove, a limit rod, a slider, a short column, a long plate, a scraper and a guide plate. The inner wall of the hydraulic valve body is fixedly connected to the filter frame, and the side walls of the filter frame are symmetrically provided with slide grooves. The inner wall of the slide groove is fixedly connected to the limit rod, and the side wall of the limit rod is slidably connected to the slider, and the side wall of the slider is fixedly connected to the short column. The side walls of the two short columns are commonly fixedly connected to the long plate, and the side walls of the long plate are fixedly connected to the scraper, and the side walls of the long plate are fixedly connected to the guide plate.

[0009] Preferably, the self-cleaning component further comprises a long hole, a storage frame, a first valve, a second valve and a spring, and the slider slides against the inner wall of the adjacent slide groove.

[0010] Preferably, a long hole is provided on the top of the scraper, and a storage frame is fixedly connected to the bottom of the hydraulic valve body.

[0011] Preferably, a first valve is fixedly mounted on the side wall of the storage frame, and a second valve is fixedly mounted on the inner wall of the storage frame.

[0012] Preferably, a spring is sleeved on the side wall of the limiting rod, and the side wall of the scraper and the side wall of the filter frame slide against each other.

[0013] Preferably, one end of the spring is fixedly connected to the inside of the slide groove, and the other end of the slide groove is fixedly connected to the top of the adjacent slider.

[0014] Beneficial effects of the present invention:

[0015] 1. In the utility model, by setting structures such as scrapers, long plates and sliders, under the action of the guide plate, the liquid first passes through the bottom of the long plate. As the water level of the liquid rises, the long plate is driven to rise, so that the scraper can scrape the impurities on the side wall of the filter frame and then drop them into the storage frame. When all the liquid has flowed through the filter frame, the long plate moves to the initial position again under the action of gravity and the elasticity of the spring, and the long hole can make the impurities on the top of the scraper fall into the storage frame.

[0016] 2. In the present invention, by providing structures such as the first valve and the second valve, the user can conveniently store and remove impurities in the liquid by controlling the opening and closing of the first valve and the second valve. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] 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.

[0022] Reference Figure 1-Figure 3 , a hydraulic valve with a self-cleaning function, comprising:

[0023] Hydraulic valve body 1;

[0024] The self-cleaning component also includes a filter frame 2, a chute 3, a limit rod 4, a slider 5, a short column 6, a long plate 7, a scraper 8 and a guide plate 10. The inner wall of the hydraulic valve body 1 is fixedly connected to the filter frame 2, and the side walls of the filter frame 2 are symmetrically provided with chute 3. The inner wall of the chute 3 is fixedly connected to the limit rod 4, and the side wall of the limit rod 4 is slidably connected to the slider 5. The side wall of the slider 5 is fixedly connected to the short column 6. The side walls of the two short columns 6 are jointly fixedly connected to the long plate 7. The side wall of the long plate 7 is fixedly connected to the scraper 8, and the side wall of the long plate 7 is fixedly connected to the guide plate 10.

[0025] The self-cleaning component further includes a long hole 9, a storage frame 11, a first valve 12, a second valve 13 and a spring 14. The slider 5 slides against the inner wall of the adjacent chute 3.

[0026] A long hole 9 is provided on the top of the scraper 8, and a storage frame 11 is fixedly connected to the bottom of the hydraulic valve body 1.

[0027] A first valve 12 is fixedly mounted on the side wall of the storage frame 11 , and a second valve 13 is fixedly mounted on the inner wall of the storage frame 11 .

[0028] The side wall of the limiting rod 4 is sleeved with a spring 14, and the side wall of the scraper 8 and the side wall of the filter frame 2 slide against each other.

[0029] One end of the spring 14 is fixedly connected to the inside of the slide groove 3 , and the other end of the slide groove 3 is fixedly connected to the top of the adjacent slider 5 .

[0030] After the liquid has passed through the filter frame 2, the long plate 7 is moved to the bottom of the filter frame 2, and the long plate 7 is driven to move. The long plate 7 drives the short column 6 and the scraper 8 to move. The scraper 8 can scrape the impurities on the side wall of the filter frame 2, and then drop them into the storage frame 11 and the top of the second valve 13. The short column 6 drives the slider 5 to move. The slider 5 moves along the side wall of the limit rod 4 and compresses the spring 14. When all the liquid has passed through the filter frame 2, the long plate 7 moves to the initial position again under the action of gravity and the elasticity of the spring 14. The long hole 9 can make the impurities on the top of the scraper 8 fall into the storage frame 11.

[0031] When the hydraulic valve body 1 is no longer in use, the first valve 12 is closed and the second valve 13 is opened, thereby conveniently removing the impurities in the impurity storage frame 11 .
