Description

Technical Field

[0001] This utility model relates to a valve cleaning device, belonging to the technical field of valve production equipment. Background Technology

[0002] Valves are widely used control devices in industry and daily life, mainly used to control the flow of fluids (such as water, gas, oil, etc.). After the valve is manufactured, its inner wall may have molding sand or impurities adhering to it. At this time, it is necessary to clean the inner wall of the valve.

[0003] Chinese patent CN220942164U discloses a valve inner wall cleaning device, including a vertical plate and a mounting bracket. A collection box is fixedly connected to the vertical plate via a connecting plate. A first water pipe is provided in the collection box at a position corresponding to the placement hole. A second water pipe is provided at the end of the first water pipe, and the second water pipe is connected to the first water pipe. The second water pipe and the first water pipe are rotatably connected. Four nozzles are provided at equal angles at the end of the second water pipe. An electric push rod can drive the mounting bracket to move downward, so that the second water pipe can be inserted into the valve. By drawing external water into the first water pipe, the water will enter the second water pipe through the first water pipe, and then be sprayed onto the inner wall of the valve through the nozzles, thereby cleaning the inner wall of the valve. This can replace manual cleaning, saving manpower. The rotation of the second water pipe can drive the nozzles to rotate, thereby thoroughly cleaning the inner wall of the valve.

[0004] While the valve cleaning device mentioned in the aforementioned patent can replace manual cleaning of the valve's inner wall, the inability of the nozzle to move up and down limits its ability to clean only fixed-height molding sand or impurities adhering to the valve's inner wall, preventing a more thorough and comprehensive cleaning. Therefore, this utility model proposes a valve cleaning device. Utility Model Content

[0022] like Figures 1-3As shown, a valve cleaning device includes a mounting platform 1, a cleaning tank 2 on the top of the mounting platform 1, a circular groove 3 at the bottom of the cleaning tank 2, a liquid outlet 4 at the bottom of the cleaning tank 2, a through hole 5 in the circular groove 3 communicating with the liquid outlet 4, a connecting pipe 6 at the center of the top of the cleaning tank 2, the two ends of the connecting pipe 6 penetrating the tank wall of the cleaning tank 2, the connecting pipe 6 and the through hole 5 being coaxially arranged, a corrugated pipe 7 connected to the bottom of the connecting pipe 6, an annular abutment 8 at the bottom of the corrugated pipe 7, an electric telescopic rod 9 on one side of the connecting pipe 6 on the top wall of the cleaning tank 2, a fastening component at the bottom of the electric telescopic rod 9, the fastening component being clamped on the corrugated pipe 7 near the annular abutment 8, a water tank 12 placed on the ground at the bottom of the mounting platform 1, a water supply component at the bottom of the water tank 12, the water supply component being connected and communicating with the connecting pipe 6.

[0023] In the above technical solution, by opening a circular groove 3 at the bottom of the cleaning tank 2, the valve can be placed vertically in the circular groove 3. The electric telescopic rod 9 moves to drive the fastening assembly to descend. Utilizing the extensibility of the bellows 7, the annular abutment 8 can be driven to abut against the top of the valve. Then, the high-pressure water pump 17 starts, drawing water from the inside of the water tank 12 and flowing through the water supply pipe 18, connecting pipe 6, bellows 7 and valve in sequence. Finally, the water flows out from the through hole 5 and the liquid outlet 4 into the water tank 12, which can perform a more comprehensive and thorough cleaning of the valve's inner wall.

[0024] In this utility model, the fastening assembly includes a lifting plate 13, which is fixedly installed at the bottom of the electric telescopic rod 9. A semi-circular groove 14 is opened at one end of the lifting plate 13 near the corrugated pipe 7, and the semi-circular groove 14 is in contact with the corrugated pipe 7. Fixed ear plates 15 are provided on the front and rear end faces of the lifting plate 13 near the end of the corrugated pipe 7. A semi-circular retaining ring 16 is fixedly connected to the fixed ear plate 15 by bolts 10 and nuts 11.

[0025] In the above technical solution, by opening a semi-circular groove 14 on the lifting plate 13 and fixing the ear plate 15, the bolt 10 and nut 11 are used to tighten the bellows 7 in the semi-circular groove 14, so that the movement of the electric telescopic rod 9 can drive the bellows 7 to extend and retract, thereby realizing the contact and separation between the annular abutment 8 and the top of the valve.

[0026] In this utility model, the water supply component includes a high-pressure water pump 17, which is installed at the bottom of the water tank 12. The output end of the high-pressure water pump 17 is connected to a water delivery pipe 18, and the end of the water delivery pipe 18 away from the high-pressure water pump 17 is connected to the top of the connecting pipe 6 and is in communication with it.

[0027] In the above technical solution, by setting a high-pressure water pump 17, water in the water tank 12 can be drawn to clean the inner wall of the valve.

[0028] In this invention, the liquid outlet 4 penetrates the mounting platform 1 and is located directly above the water tank 12. The inner diameter of the liquid outlet 4 is smaller than the inner diameter of the water supply pipe 18 and the connecting pipe 6. By setting the inner diameter of the liquid outlet 4 to be smaller than the inner diameter of the water supply pipe 18 and the connecting pipe 6, a pressure difference can be created in the water flow, resulting in a more thorough cleaning of the valve's inner wall.

[0029] In this utility model, support columns 19 are provided at the four corners of the water tank 12, and filter frames 20 are placed on the support columns 19. Each of the top two ends of the filter frame 20 is provided with a handle 21.

[0030] In the above technical solution, the filter frame 20 is set to facilitate the filtration of impurities in the water flowing out from the liquid outlet 4, and the handle 21 is set to facilitate the removal of the filter frame 20 from the water tank 12, which makes it convenient to clean the filtered impurities.

[0031] It is worth noting that the electric telescopic rod 9 and the high-pressure water pump 17 of this utility model are electrically connected to an external power source through a controller, which is well known to those skilled in the art, and therefore not described in detail in this utility model.

[0032] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
