Description

Technical Field

[0001] This utility model relates to the field of check valve inner wall cleaning technology, and in particular to a valve inner wall cleaning device for check valve production and processing. Background Technology

[0002] In the manufacturing process of check valves, cleaning the valve's inner wall is a crucial and highly challenging step. As a key control component, check valves are widely used in various fluid transport systems, and the cleanliness of their inner wall directly affects the valve's sealing performance, flow characteristics, and overall service life. If stains, impurities, or debris generated during processing remain on the inner wall, it will not only lead to problems such as poor sealing and fluid leakage during operation, affecting the stable operation of the entire system, but also accelerate valve wear due to continuous friction from impurities on the inner wall, shortening its service life and increasing maintenance and replacement costs for the company.

[0003] The patent with publication number CN213134170U, entitled "A Valve Inner Wall Cleaning Device for Check Valve Production and Processing," discloses a valve inner wall cleaning device for check valve production and processing. The device includes a base, a platform welded to the top of the base, a servo motor bolted to the bottom of the platform, and a lead screw connected to the output end of the servo motor via a coupling. One end of the lead screw passes through the platform and has sliding grooves on both sides. A connecting block is slidably installed within the sliding grooves. However, this patent lacks a stain removal function, resulting in the stains left behind during check valve cleaning not being removed promptly, thus reducing the cleaning effect on the check valve's inner wall. Furthermore, the cleaned stains can negatively impact the working environment. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a valve inner wall cleaning device for check valve production and processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3 A valve inner wall cleaning device for check valve production and processing includes a base 1. Four fixing rods 2 are fixed to the upper end of the base 1. The upper ends of the four fixing rods 2 are fixed to the same top plate 3. A movable plate 12 is provided below the top plate 3. A rotating tube 6 is vertically inserted through the movable plate 12. The rotating tube 6 and the movable plate 12 are rotatably connected by bearings. The upper end of the rotating tube 6 passes through the top plate 3. Two cleaning mechanisms are provided on the side wall of the rotating tube 6 near the upper end. The cleaning mechanism includes a connecting block 8. A brush rod 10 is fixed to the upper end of the connecting block 8. Brush bristles 11 are provided on the side wall of the brush rod 10. Two connecting bolts 9 are inserted through the side wall of the connecting block 8. A connecting screw hole 22 is provided on the side wall of the rotating tube 6 to mate with the connecting bolts 9. The connecting bolts 9 are screwed into the inside of the connecting screw hole 22. Through the design of the connecting bolts 9 and the connecting screw hole 22, the connecting block 8, brush rod 10 and brush bristles 11 can be replaced.

[0020] Four suction ports 7 are provided on the side wall near the upper end of the rotating pipe 6. The lower end of the moving plate 12 is provided with a rotating mechanism connected to the rotating pipe 6. The rotating mechanism includes a motor 19 installed at the lower end of the moving plate 12. The output shaft of the motor 19 is fixedly connected to a first gear 20. A second gear 21 is fixedly sleeved on the side wall of the rotating pipe 6. The second gear 21 meshes with the first gear 20.

[0021] The upper end of the base 1 is provided with a lifting mechanism connected to the movable plate 12. The lifting mechanism includes an electric push rod 17 installed on the upper end of the base 1. The telescopic end of the electric push rod 17 faces upward and is fixedly connected to a connecting frame 13. The connecting frame 13 is fixedly connected to the lower end of the movable plate 12. Two guide rods 16 are provided through the lower end of the connecting frame 13. The guide rods 16 are slidably connected to the connecting frame 13. The lower end of the guide rods 16 is fixedly connected to the upper end of the base 1. The guide rods 16 can guide the movement of the connecting frame 13 and ensure the stability of the movement of the connecting frame 13.

[0022] The lower end of the rotating tube 6 is connected to a vacuuming mechanism, which includes a vacuum cleaner 18 mounted on the upper end of the base 1. The suction end of the vacuum cleaner 18 is connected to a hose 15. The end of the hose 15 away from the vacuum cleaner 18 is connected to the lower end of the rotating tube 6 through a rotary joint 14. The rotary joint 14 ensures that the hose 15 does not get tangled when the rotating tube 6 rotates.

[0023] The top plate 3 is provided with two positioning mechanisms, which are symmetrically arranged on both sides of the rotating pipe 6. The positioning mechanism includes a positioning screw 4 fixedly connected to the top plate 3, and a fixing nut 5 is threaded onto the positioning screw 4. The positioning screw 4 and the fixing nut 5 can be used to position and fix the check valve body.

[0024] In use, the check valve body to be cleaned is placed upside down on the top plate 3, with the valve body opening aligned with the axis of the rotating pipe 6. Positioning screws 4 are inserted into the holes on the flange of the check valve body. Then, the fixing nuts 5 on the two positioning screws 4 are rotated, clamping and fixing the valve body on both sides through the downward pressure of the nuts, ensuring that the valve body axis remains coaxial with the rotating pipe 6. The motor 19 is started to drive the first gear 20, which in turn drives the second gear 21 and the rotating pipe 6 to rotate. The brush bristles 11 are used to scrape the inner wall of the valve body for cleaning. The electric push rod 17 is then activated to push the connecting frame 13 upward, causing the moving plate 12 to rise, allowing the rotating pipe 6 to carry the brush bristles 11. The guide rod 16 moves upward inside the valve body, restricting the connecting bracket 13 to move only vertically, thus thoroughly cleaning the inner wall of the valve body. At the same time, the vacuum cleaner 18 is started, forming a negative pressure channel with the hose 15, rotary joint 14 and rotating tube 6. The vacuum cleaner 18 continuously sucks in the cavity inside the rotating tube 6, transporting the dirt scraped off by the brush bristles 11 through the suction port 7 → rotating tube 6 → hose 15 to the vacuum cleaner 18 for filtration and collection. The rotary joint 14 ensures that the hose 15 does not get tangled when the rotating tube 6 rotates. After cleaning is completed, the electric push rod 17 retracts, driving the rotating tube 6 out of the valve body. After turning off the motor 19 and the vacuum cleaner 18, the fixing nut 5 is loosened and the valve body is removed.

[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
