Description

Technical Field

[0001] The present invention relates to the technical field of valve cleaning, and in particular to a device for cleaning the internal structure of a valve. Background Art

[0002] Valves, as core control components in fluid conveying systems, perform multiple functions, including shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion, and overflow and pressure relief. Ball valves and gate valves, among the most widely used and commonly used valve types, are susceptible to the adhesion and accumulation of impurities carried by the fluid medium in their internal flow passages and sealing structures during long-term operation. The retention of such impurities not only increases the valve's opening and closing resistance and degrades its sealing performance, but can also cause functional failures such as sticking and leakage, impacting the valve's safe and stable operation. Therefore, regular cleaning and maintenance of the valve's internal flow passages is essential to ensure continued reliable operation and extend its service life.

[0003] For example, the patent document with the publication number "CN216728438U" and the name "A valve cleaning device for valve production" includes a base plate, a gantry is installed on the upper surface of the base plate, and the top of the left inner wall and the right inner wall of the gantry are both installed with limit rails, a sliding plate is slidably connected to the limit rail, a cleaning rod is slidably connected to the inside of the sliding plate, a brush is installed on the bottom of the outer surface of the cleaning rod, a driven gear is sleeved on the top of the cleaning rod, and the left side of the lower surface of the sliding plate is rotatably connected to the transmission shaft, the bottom end of the transmission shaft is installed with a driving gear, the driving gear and the driven gear are meshed, and a driving motor is provided on the left side of the upper surface of the sliding plate, and the output end of the driving motor is keyed to the top of the transmission shaft. The driving motor drives the transmission shaft to rotate, so that the transmission shaft drives the cleaning rod to rotate through the driving gear and the driven gear, and the cleaning rod drives the brush to clean the inside of the valve.

[0004] However, in the above literature, during the process of cleaning the valve, although the sleeve drives the bristles to rotate to clean the inside of the valve, it is difficult to thoroughly clean the impurities adhered and accumulated inside the valve to a certain extent by relying solely on the rotation of the bristles to clean the inside of the valve, resulting in poor cleaning effect. Summary of the Invention

[0005] The purpose of the present invention is to address the deficiencies of the existing technology and propose a valve internal structure cleaning device to solve the technical problem mentioned in the background technology that it is difficult to thoroughly clean the impurities adhered and accumulated inside the valve to a certain extent by relying solely on the rotation of the bristles to clean the inside of the valve.

[0006] To achieve the above object, the present invention adopts the following technical solutions: A device for cleaning the internal structure of a valve comprises a base plate, a movable plate is provided above the base plate, a lifting assembly is provided on the base plate for driving the movable plate to move vertically, a placing platform for placing the valve is provided on the top of the base plate, a mounting frame is provided below the movable plate, a reciprocating assembly is provided on the movable plate for driving the mounting frame to move back and forth vertically, a sleeve is rotatably provided on the mounting frame, bristles are evenly provided on the outer periphery of the sleeve, and a transmission assembly is provided on the mounting frame for driving the sleeve to rotate. When the sleeve drives the bristles to enter the interior of the valve, the reciprocating assembly drives the mounting frame to move back and forth vertically, the mounting frame drives the sleeve to move back and forth vertically, and at the same time, the mounting frame drives the sleeve to rotate through the transmission assembly, so that the sleeve drives the bristles to rotate and also drives the bristles to reciprocate vertically.

[0007] Working Principle: To clean the interior of a valve, first place the valve on a table. The lifting assembly is then activated to move the movable plate downward, which in turn drives the mounting frame downward. This in turn drives the sleeve downward. The sleeve drives the bristles on its outer periphery into the valve interior, and the movable plate stops moving downward.

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 and Figure 2The figure shows a device for cleaning the internal structure of a valve. The device comprises a base plate 1, with a movable plate 2 mounted at intervals above the base plate 1. A lifting assembly is mounted on the base plate 1 to drive the movable plate 2 vertically. The lifting assembly includes four hydraulic push rods 3, each vertically fixed to the top surface of the base plate 1, corresponding to each of the four corners of the base plate 1. The output ends of the four hydraulic push rods 3 are fixedly connected to the movable plate 2. Each hydraulic push rod 3 is connected to an external hydraulic oil pump via an oil pipe. A placement platform 4 is mounted at the center of the top surface of the base plate 1 for placing a valve 5. A plurality of positioning posts 401 are fixedly mounted on the top surface of the placement platform 4, arranged in an array along its circumference. The plurality of positioning posts 401 are designed to engage with the flange holes of the valve 5. When cleaning the valve 5, the flange holes of the valve 5 are first plugged into the positioning posts 401 to provide initial securement of the valve 5 and prevent it from moving during the cleaning process. To further enhance the securement effect, the outer periphery of the positioning posts 401 is threaded with nuts (not shown). After the flange hole on the valve 5 is plugged into the positioning column 401, the valve 5 can be further fixed by tightening the nut to ensure that the valve 5 remains stable during the cleaning process.

[0022] like Figure 1 and Figure 3 As shown, a mounting frame 6 is installed directly below the movable plate 2, and the mounting frame 6 is hollow. A sleeve 8 is installed at the center of the mounting frame 6 for vertical rotation. The sleeve 8 is rotatably connected to the mounting frame 6 through a bearing. The bearing is installed on the mounting frame 6, and the end of the sleeve 8 is inserted into the center hole of the bearing, and the end of the sleeve 8 is fixedly connected to the inner wall of the center hole of the bearing to achieve rotational installation. Brush bristles 9 are evenly installed on the outer periphery of the bottom of the sleeve 8. A reciprocating component for driving the mounting frame 6 to reciprocate vertically is installed on the movable plate 2, as shown in FIG. Figure 3As shown, the reciprocating assembly includes a motor 11 and a sliding rod 7. There are two sliding rods 7. The movable plate 2 is symmetrically provided with mounting holes. The two sliding rods 7 are vertically slidably installed in the corresponding two mounting holes one by one. The bottom ends of the two sliding rods 7 are fixedly connected to the mounting frame 6, and a horizontally arranged connecting rod 14 is fixedly installed between the top ends of the two sliding rods 7. The connecting rod 14 has a slide groove 15 along its length. A support block 10 is fixedly installed on the top of the movable plate 2. The motor 11 is fixedly installed on the top of the support block 10. A drive rod 12 is fixedly installed on the output end of the motor 11. A sliding column 13 is fixedly installed on the end of the drive rod 12 away from the motor 11. The sliding column 13 is slidably connected to the slide groove 15, and the sliding column 13 can rotate relative to the slide groove 15. When cleaning the inside of the valve 5, the valve 5 is fixed on the top of the placement table 4, and then the hydraulic push rod 3 drives the movable plate 2 to move downward, and the movable plate 2 drives the installation frame 6 to move downward through the sliding rod 7, and the installation frame 6 drives the sleeve 8 to move downward, and the sleeve 8 drives the brush bristles 9 on its periphery to enter the inside of the valve 5. Then, the motor 11 is started, and the motor 11 drives the driving rod 12 to rotate, and the driving rod 12 drives the sliding column 13 to rotate. During the sliding process of the sliding column 13 along the slide groove 15, it drives the connecting rod 14 to move back and forth up and down, and the connecting rod 14 drives the two sliding rods 7 to move back and forth up and down, and the two sliding rods 7 drive the installation frame 6 to move back and forth up and down, and the installation frame 6 drives the sleeve 8 to move vertically back and forth, and the sleeve 8 drives the brush bristles 9 to move back and forth up and down to clean the inside of the valve 5.

[0023] like Figure 3 and Figure 4 As shown, a transmission assembly for driving the sleeve 8 to rotate is installed on the mounting frame 6. The transmission assembly includes two racks 17 and two rotating shafts 18. The two rotating shafts 18 are rotatably mounted on one side of the corresponding mounting frame 6, and the two rotating shafts 18 are symmetrically arranged. A driving bevel gear 20 is fixedly sleeved on one end of the rotating shaft 18, and a driven bevel gear 21 is fixedly sleeved on the outer periphery of the sleeve 8. The driven bevel gear 21 meshes with the driving bevel gear 20. A U-shaped frame 16 is symmetrically fixedly mounted on the bottom surface of the movable plate 2. Two racks 17 are fixedly mounted in the corresponding U-shaped frame 16 in the vertical direction, one in front and one behind. A gear 19 is fixedly sleeved on the other end of the rotating shaft 18, and the gear 19 meshes with the corresponding rack 17. During the up and down movement of the mounting frame 6, the rotating shaft 18 is simultaneously driven to move back and forth, and the rotating shaft 18 drives the gear 19 to move back and forth. During the up and down reciprocating movement of the gear 19, it engages with the corresponding rack 17 to rotate clockwise and counterclockwise, so that the gear 19 drives the rotating shaft 18 to rotate, and the rotating shaft 18 drives the active bevel gear 20 to rotate, and the active bevel gear 20 drives the driven bevel gear 21 to rotate, and the driven bevel gear 21 drives the sleeve 8 to rotate, and then the sleeve 8 drives the bristles 9 to move back and forth, and at the same time drives the bristles 9 to rotate clockwise and counterclockwise, thereby improving the cleaning effect of the bristles 9 on the inside of the valve 5.

[0024] As the mounting frame 6 moves up and down, it drives the rotating shaft 18 to reciprocate vertically. The rotating shaft 18 drives the gear 19 up and down. During this process, the gear 19, meshing with the corresponding rack 17, rotates alternately clockwise and counterclockwise. This, in turn, drives the driving bevel gear 20 via the rotating shaft 18. The driving bevel gear 20, in turn, drives the driven bevel gear 21, which in turn drives the sleeve 8. Furthermore, while the sleeve 8 drives the bristles 9 to reciprocate up and down, it also drives the bristles 9 to rotate alternately clockwise and counterclockwise, further enhancing the cleaning effect of the bristles 9 on the interior of the valve 5.

[0025] like Figure 4 、 Figure 5 and Figure 7 As shown, the bottom of the sleeve 8 is provided with a plurality of cleaning rings along its axial direction, and the bristles 9 are evenly fixedly installed on the outer side of the cleaning rings. The cleaning ring includes two cleaning half rings 26 arranged in an annular shape, and an elastic component is installed between the ends of the two cleaning half rings 26 close to each other. The elastic component includes two fixing plates 31, and the two fixing plates 31 are respectively fixedly installed on the ends of the corresponding cleaning half rings 26. The two fixing plates 31 are symmetrically slidably penetrated with mounting posts 32, and baffles 33 are fixedly installed at both ends of the mounting posts 32. A spring 34 is fixedly installed between the baffle 33 and the corresponding fixing plate 31. The spring 34 is sleeved on the outer periphery of the mounting post 32, and one end of the spring 34 is fixedly connected to the corresponding baffle 33, and the other end of the spring 34 is fixedly connected to the corresponding fixing plate 31.

[0026] like Figures 5 to 8As shown, an extrusion assembly for extruding two cleaning half rings 26 to move in opposite directions is installed between the sleeve 8 and the movable plate 2. The extrusion assembly includes a first extrusion rod 22, a connecting rod 23 and a second extrusion rod 24, and the first extrusion rod 22 is slidably installed in the sleeve 8. The top end of the first extrusion rod 22 is rotatably mounted with the movable plate 2. The connecting rod 23 is fixedly mounted on the bottom of the first extrusion rod 22, and the connecting rod 23 is a truncated cone structure. The second extrusion rod 24 is fixedly mounted on the bottom of the connecting rod 23. The radial width of the top surface of the connecting rod 23 is smaller than the radial width of its bottom surface. The radial dimension of the first extrusion rod 22 matches the radial dimension of the top surface of the connecting rod 23, and the radial dimension of the second extrusion rod 24 matches the radial dimension of the bottom surface of the connecting rod 23. In addition, the axes of the first extrusion rod 22, the connecting rod 23, the second extrusion rod 24 and the sleeve 8 are all on the same straight line. Interconnected guide grooves 25 are defined along the length of each of the first extrusion rod 22, the connecting rod 23, and the second extrusion rod 24. The guide grooves 25 on the outer side of the connecting rod 23 are arranged at an angle. Guide rods 30 are symmetrically fixed to the inner side of the top of the sleeve 8. These guide rods 30 slide in engagement with the corresponding guide grooves 25 on the outer side of the first extrusion rod 22. This sliding engagement between the guide rods 30 and the corresponding guide grooves 25 enables both vertical movement of the sleeve 8 relative to the first extrusion rod 22 and synchronous rotation of the first extrusion rod 22, driven by the guide rods 30.

[0027] like Figure 5 、 Figure 7 and Figure 8As shown, the bottom of the sleeve 8 is provided with a plurality of axially spaced through-holes 27 on both sides thereof. A squeeze post 28 is horizontally slidably mounted within the through-holes 27. One end of the squeeze post 28 slides in engagement with the guide groove 25. The end of the squeeze post 28 that slides in engagement with the guide groove 25 is hemispherical, reducing friction as the squeeze post 28 slides along the guide groove 25. The other end of the squeeze post 28 is fixedly connected to the center of the corresponding cleaning half-ring 26. In the initial state, the hemispherical end of the squeeze post 28 is located within the guide groove 25 outside the first squeeze rod 22. At this point, the spring 34 is in its natural position, and the two cleaning half-rings 26 are not separated, facilitating the sleeve 8 to drive the bristles 9 into the interior of the valve 5. As the sleeve 8 drives the squeeze post 28 downward, the hemispherical end of the squeeze post 28 slides in engagement with the inclined guide groove 25 outside the connecting rod 23, gradually pushing the corresponding cleaning half-ring 26 away from the sleeve 8 while compressing the corresponding spring 34. The cleaning half-ring 26 drives the outer bristles 9 to press against the inner wall of the valve 5, causing the bristles 9 to deform, thereby increasing the contact pressure between the bristles 9 and the inner wall of the valve 5, and improving the cleaning effect on the interior of the valve 5. When the hemispherical end of the extrusion column 28 enters the guide groove 25 outside the second extrusion rod 24, it moves up and down within the guide groove 25, keeping the cleaning half-ring 26 stationary, thereby maintaining a constant pressure of the bristles 9 on the inner wall of the valve 5 and ensuring the stability of the cleaning effect.

[0028] like Figure 4 and Figure 5 As shown, the first extrusion rod 22, the connecting rod 23, and the second extrusion rod 24 all have interconnected channels along their axial directions. Multiple water outlets 29 are formed on both sides of the second extrusion rod 24 along its length, and the multiple water outlets 29 are all connected to the channels. The top of the first extrusion rod 22 extends above the movable plate 2, and the top of the first extrusion rod 22 is connected to an external water supply device via a rotary joint. This allows the external water supply device to continuously and stably supply water to the channel within the first extrusion rod 22 when the first extrusion rod 22 rotates, ensuring that the water supply process is not affected by the rotation of the first extrusion rod 22. When the second extrusion rod 24 is fully inserted into the valve 5, the external water supply device is activated to inject water into the channel. Water flows through the water outlets 29 connected to the channel and sprays onto the inner wall of the valve 5, moistening impurities adhered to the inner wall of the valve 5 to enhance the cleaning effect. This is to prevent the sleeve 8 from moving downward to block the water outlets 29, hindering water spraying and causing water waste.

[0029] A controller (not shown) is mounted on the placement table 4. This controller is electrically connected to the motor 11 and the external water supply device, and is internally embedded with a PLC control program. This controller achieves intelligent water control by precisely controlling the start and stop of the external water supply device. When the sleeve 8 moves downward to begin blocking the water outlet 29 at the top of the first extrusion rod 22, the PLC program instructs the external water supply device to suspend water supply. When the sleeve 8 moves upward to re-expose the water outlet 29 at the top of the first extrusion rod 22, the PLC program instructs the external water supply device to resume water supply, cleaning the interior of the valve 5 again. This ensures that the bristles 9 have cleaned the inner wall of the valve 5 and that any impurities remaining on the inner wall of the valve 5 are rinsed away. This control logic dynamically matches the displacement of the sleeve 8 with the water supply status, ensuring the continuity of the cleaning operation while effectively improving water resource utilization. Since the sleeve 8 drives the first extrusion rod 22 to rotate while moving up and down, the first extrusion rod 22 drives the second extrusion rod 24 to rotate synchronously through the connecting rod 23. Therefore, in the process of spraying water to the inner wall of the valve 5, the second extrusion rod 24 drives the water outlet 29 to rotate and spray water to the inner wall of the valve 5, thereby achieving a more comprehensive cleaning effect on the inside of the valve 5.

[0030] The controller is also electrically connected to an external hydraulic oil pump. The controller controls the hydraulic oil pump to start, and the hydraulic oil pump controls the four hydraulic push rods 3 to extend and retract simultaneously through the oil pipe, so that the four hydraulic push rods 3 drive the movable plate 2 to move up and down.

[0031] like Figure 2 As shown, support columns 402 are evenly fixed to the bottom of the placement table 4. The bottom of the support columns 402 is fixedly connected to the placement table 4. The center of the placement table 4 has an opening that matches the size of the water outlet pipe of the valve 5. A sewage pipe 403 is fixedly installed at the bottom of the opening. Wastewater generated during the cleaning process can flow into the sewage pipe 403 through the opening on the placement table 4 and be discharged to the outside through the sewage pipe 403.

[0032] Working principle: In the initial position, the second extrusion rod 24 is located below the sleeve 8 to prevent the sleeve 8 from covering the water outlet 29 .

[0033] To clean the interior of valve 5, first mate the flange hole of valve 5 with positioning column 401. Then, hydraulic push rod 3 is activated to move movable plate 2 downward. This moves first extrusion rod 22 downward, which in turn moves second extrusion rod 24 downward via connecting rod 23. Second extrusion rod 24 moves downward and extends into the interior of valve 5. Simultaneously, movable plate 2 moves downward, driving mounting frame 6 downward via sliding rod 7. Mounting frame 6 moves sleeve 8 downward, which in turn moves several cleaning rings downward. After the cleaning rings drive the bristles 9 on their outer circumferences into the interior of valve 5, movable plate 2 stops moving downward.

[0034] Start the motor 11, the motor 11 drives the driving rod 12 to rotate, the driving rod 12 drives the sliding column 13 to rotate, and the sliding column 13 drives the connecting rod 14 to move back and forth up and down while sliding along the slide groove 15. The connecting rod 14 drives the two sliding rods 7 to move back and forth up and down, and the two sliding rods 7 drive the mounting frame 6 to move back and forth up and down, and the mounting frame 6 drives the sleeve 8 to move vertically back and forth up and down, and the sleeve 8 drives the cleaning ring to move back and forth up and down through the extrusion column 28, and the cleaning ring drives the bristles 9 to move up and down to clean the inside of the valve 5.

[0035] During the vertical movement of the mounting frame 6, the rotating shaft 18 is simultaneously driven to reciprocate vertically. The rotating shaft 18 drives the gear 19 to move up and down. During this process, the gear 19 rotates alternately clockwise and counterclockwise under the meshing action with the corresponding rack 17. Thus, the gear 19 drives the driving bevel gear 20 to rotate through the rotating shaft 18. The driving bevel gear 20 drives the driven bevel gear 21 to rotate. The driven bevel gear 21 drives the sleeve 8 to rotate. The sleeve 8 drives the cleaning ring to rotate. In the process of the cleaning ring driving the bristles 9 to move up and down, it also drives the bristles 9 to rotate alternately clockwise and counterclockwise, further improving the cleaning effect of the bristles 9 on the inside of the valve 5.

[0036] In the initial state, the hemispherical end of the squeezing column 28 is located in the guide groove 25 on the outside of the first squeezing rod 22. At this time, the spring 34 is in a natural state, and the two cleaning half-rings 26 are not separated. After entering the valve 5, the bristles 9 just contact the inner wall of the valve 5. Therefore, when the sleeve 8 drives the squeezing column 28 downward, the hemispherical end of the squeezing column 28 slides with the inclined guide groove 25 on the outside of the connecting rod 23, gradually pushing the corresponding cleaning half-ring 26 away from the sleeve 8. At the same time, the cleaning half-ring 26 drives the corresponding fixing plate 31 to move and compresses the corresponding spring 34. The cleaning half-ring 26 drives the outer bristles 9 to press against the inner wall of the valve 5, causing the bristles 9 to deform, thereby increasing the contact pressure between the bristles 9 and the inner wall of the valve 5 and improving the cleaning effect on the interior of the valve 5. When the hemispherical end of the extrusion column 28 enters the guide groove 25 outside the second extrusion rod 24, it can keep the cleaning half ring 26 stationary when it moves up and down in the guide groove 25, thereby maintaining a constant pressure of the bristles 9 on the inner wall of the valve 5 and ensuring the stability of the cleaning effect.

[0037] At the same time, after the second extrusion rod 24 extends into the interior of the valve 5, the external water supply device is activated to inject water into the channel. The water flows through the water outlet 29 connected to the channel and sprays onto the inner wall of the valve 5, moistening the impurities adhering to the inner wall of the valve 5, making it easier for the bristles 9 to clean the impurities adhering to the valve 5. When the sleeve 8 moves downward to begin to cover the water outlet 29 at the top of the first extrusion rod 22, the controller instructs the external water supply device to suspend water supply; when the sleeve 8 moves upward to expose the water outlet 29 at the top of the first extrusion rod 22 again, the controller controls the external water supply device to resume water supply, and the interior of the valve 5 is cleaned again, so as to rinse away the impurities remaining on the inner wall of the valve 5 after the bristles 9 have cleaned the inner wall of the valve 5.

[0038] Since the first extrusion rod 22 is driven to rotate by the guide rod 30 during the up and down movement of the sleeve 8, and the first extrusion rod 22 drives the second extrusion rod 24 to rotate synchronously through the connecting rod 23, the second extrusion rod 24 drives the water outlet 29 to rotate and spray water to the inner wall of the valve 5 during the process of spraying water to the inner wall of the valve 5, thereby achieving a more comprehensive cleaning effect on the inside of the valve 5.

[0039] The sewage generated during the cleaning process can flow into the sewage pipe 403 through the opening on the placement table 4 and be discharged to the outside through the sewage pipe 403.

[0040] In the present invention, the sleeve 8 drives the cleaning ring to move back and forth up and down, while also driving the cleaning ring to rotate. In the process of the cleaning ring driving the bristles 9 to move back and forth up and down, the bristles 9 are also driven to rotate alternately clockwise and counterclockwise, thereby improving the cleaning effect of the bristles 9 on the inside of the valve 5. In addition, in the process of the sleeve 8 driving the extrusion column 28 to move downward, the hemispherical end of the extrusion column 28 slides with the guide groove 25 inclined on the outside of the connecting rod 23, gradually pushing the corresponding cleaning semi-ring 26 to move in a direction away from the sleeve 8. The cleaning semi-ring 26 drives the bristles 9 on its outside to press against the inner wall of the valve 5, causing the bristles 9 to deform, thereby increasing the contact pressure between the bristles 9 and the inner wall of the valve 5, and further improving the cleaning effect on the inside of the valve 5.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
