Description

Technical Field

[0001] This utility model relates to the field of check valve technology, specifically a check valve with an anti-clogging and cleaning structure. Background Technology

[0002] A check valve allows the medium to flow in only one direction and prevents flow in the opposite direction. These valves are typically automatic. Under the pressure of the fluid flowing in one direction, the valve disc opens. When the fluid flows in the opposite direction, the fluid pressure and the weight of the valve disc combine to act on the valve seat, thus cutting off the flow. However, in existing check valves, impurities in the fluid can enter the valve, affecting its sealing performance and lifespan. After prolonged use, existing check valves are prone to backflow, further compromising their sealing quality. Utility Model Content

[0003] The purpose of this utility model is to provide a check valve with an anti-clogging and cleaning structure to solve the problems mentioned in the background art, such as impurities in the fluid entering the interior of the check valve during use, affecting the sealing effect of the check valve, and also affecting the service life of the check valve.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a check valve with an anti-clogging and cleaning structure, such as... Figure 1 , Figure 2 and Figure 3As shown, the system includes an anti-clogging filter structure 1, which includes a first water pipe 11 connected to a filter assembly 12. A cleaning assembly 13 is slidably connected to the filter assembly 12, and a sealing assembly 14 is rotatably connected to the filter assembly 12. The sealing assembly 14 is sealed and fixed by an auxiliary fixing assembly 15. Both the filter assembly 12 and the pushing assembly 16 are fixed with pushing assemblies 16. The filter assembly 12 is connected to a second water pipe 17 and includes a filter tube 121. A filter screen 122 is installed and removed inside the filter tube 121. The cleaning assembly 13 includes a first storage box 131, which extends and retracts to adjust the positions of a first cleaning plate 132 and a second cleaning plate 133 via a telescopic structure. The second cleaning plate 133 is located at the position of the first cleaning plate 132. Between plates 132, the sealing assembly 14 includes a first fixing block 141, a first rotating rod 142 is fixed between the first fixing blocks 141, a first connecting plate 143 is rotatably connected to the first rotating rod 142, and a first sealing cover 144 is fixed to the first connecting plate 143. The auxiliary fixing assembly 15 includes a second fixing block 151, a screw 153 is rotatably connected between the second fixing blocks 151, the screw 153 is engaged in the limiting hole opened on the limiting plate 152, and a nut is rotatably connected to the screw 153. The pushing assembly 16 includes a hydraulic pipe 161, a connecting rod 162 is telescopically adjusted via a telescopic structure, a second rotating rod 163 is fixed to the connecting rod 162, and the second rotating rod 163 is rotatably connected between the third fixing blocks 164.

[0028] In this application, the telescopic structure is a hydraulic cylinder, which is existing technology. The hydraulic cylinder on the first storage box 131 drives the second cleaning plate 133 and the first cleaning plate 132 to move through the hydraulic rod, so that the second cleaning plate 133 and the first cleaning plate 132 automatically clean the filter screen 122 and the inner wall of the filter tube 121. The diameter of the second cleaning plate 133 is smaller than the diameter of the first cleaning plate 132.

[0029] Specifically, there are two sets of push components 16, which are symmetrically arranged about the central axis of the filter tube 121. A rubber sealing ring is provided between the filter tube 121 and the first sealing cover 144 to ensure the sealing effect.

[0030] Furthermore, a nut rotates on the screw 153, and a rubber pad passes through between the nut and the limiting plate 152 to ensure the limiting effect;

[0031] In the above scheme, fluid enters the filter pipe 121 through the first water pipe 11 and is filtered with the assistance of the filter screen 122. The filtered fluid is discharged through the second water pipe 17. With the assistance of the hydraulic cylinder in the first storage tank 131, the first cleaning plate 132 and the second cleaning plate 133 are moved by the hydraulic rod, thereby automatically cleaning the filter screen 122 and the filter pipe 121. The hydraulic cylinder in the hydraulic pipe 161 drives the connecting rod 162 to be stretched by the hydraulic rod. The connecting rod 162 is rotatably connected to the second rotating rod 163 between the third fixed blocks 164. When the connecting rod 162 is stretched, the angle is adjusted by the second rotating rod 163 on the third fixing block 164. The first sealing cover 144 rotates with the assistance of the first rotating rod 142 and the first connecting plate 143 between the first fixing blocks 141, thereby opening or closing the first sealing cover 144. When the first sealing cover 144 leaks, the screw 153 between the second fixing blocks 151 is rotated. The screw 153 is engaged in the limiting groove opened on the limiting plate 152. The nut on the screw 153 is rotated to limit and fix the filter tube 121 and the first sealing cover 144, ensuring the sealing effect.

[0032] like Figure 1 and Figure 2 As shown, the check valve assembly 2 includes a valve body 21, an inlet 22 is provided inside the valve body 21, a top cover 24 is fixed on the valve body 21, a hydraulic tank 25 is fixed on the upper side of the top cover 24, and the hydraulic tank 25 adjusts the sealing valve disc 23 by telescopic structure.

[0033] The hydraulic tank 25 is equipped with a control device for controlling the overall equipment.

[0034] Specifically, a third water pipe 31 is fixed on the right side of the valve body 21, and the right side of the valve body 21 is connected to a water supply pipe 321, which is located inside the third water pipe 31.

[0035] In the above scheme, with the assistance of the hydraulic cylinder in the hydraulic tank 25 on the upper side of the top cover 24, the hydraulic rod drives the sealing valve 23 to open the water inlet 22, and the fluid is discharged through the valve body 21 and the water inlet 22 on the right side of the valve body 21.

[0036] like Figure 1 , Figure 4 and Figure 5As shown, an auxiliary sealing structure 3 is rotatably connected inside the check valve assembly 2. The auxiliary sealing structure 3 includes a third water pipe 31, an auxiliary sealing assembly 32 is fixed on the third water pipe 31, the auxiliary sealing assembly 32 includes a water supply pipe 321, a fourth fixing plate 322 is fixed on the upper side of the water supply pipe 321, a third rotating rod 323 is fixed between the fourth fixing plates 322, a retaining ring 324 passes through the third rotating rod 323, a second connecting plate 325 is rotatably connected to the third rotating rod 323, a second sealing cover 326 is fixed on the second connecting plate 325, and a rubber sealing ring is provided between the water supply pipe 321 and the second sealing cover 326.

[0037] A rubber sealing ring is provided between the water supply pipe 321 and the second sealing cover 326 to ensure the sealing effect;

[0038] In the above scheme, the high-pressure fluid in the water pipe 321 pushes the second sealing cover 326. With the assistance of the third rotating rod 323 and the snap ring 324 between the fourth fixed plate 322, the second sealing cover 326 drives the second connecting plate 325 to rotate. The rotation of the second connecting plate 325 drives the second sealing cover 326 to open, ensuring the normal passage of fluid. When the fluid flows in the opposite direction, the fluid pressure and the weight of the second sealing cover 326 itself cut off the flow of fluid, thereby preventing backflow of fluid and achieving a double-layer seal, increasing practicality.

[0039] Working principle: When using this check valve with anti-clogging cleaning structure, the external power supply is turned on, the fluid is filtered by the anti-clogging filter structure 1, the fluid is blocked or allowed to flow normally by the check valve assembly 2, and the check valve is double-sealed by the auxiliary sealing structure 3.
