Description

Technical Field

[0001] This utility model relates to the field of valve body processing technology, specifically to an auxiliary surface cleaning device for ball valve bodies after processing. Background Technology

[0002] After the ball valve body is machined, its auxiliary surface often has residual impurities such as iron filings, oil stains, and cutting fluid. These impurities not only affect the appearance quality of the valve body, but may also lead to problems such as reduced sealing performance and accelerated wear, thereby affecting the service life and operational reliability of the ball valve. Existing cleaning devices have defects such as low cleaning efficiency, incomplete cleaning, and insufficient automation, which make it difficult to meet the surface cleaning requirements of high-precision ball valve bodies. There is an urgent need to design a new auxiliary surface cleaning device.

[0003] Currently, most ball valve body cleaning methods involve manual surface treatment after machining or direct rinsing with water. These methods are generally inefficient, time-consuming, and labor-intensive, leading to increased personnel costs. Utility Model Content

Mounting plates are fixedly connected to the middle of both sides of the inner end of the cleaning tank and to the front and rear ends. A liquid pipe is installed between the mounting plates and the liquid pump. An auxiliary cleaning nozzle is mounted on the inner end of the mounting plate. After the valve body enters the cleaning tank, the liquid pump first draws liquid, and then the auxiliary cleaning nozzle sprays cleaning fluid onto the surface of the valve body.

Together with the electrically controlled telescopic column 319, the valve body is lowered into the cleaning tank 1 for cleaning.

[0039] Please see Figure 1-5 Furthermore, based on Embodiment 1, the post-drying treatment mechanism 4 includes a drying chamber 41, which is fixedly connected to the top center of the left and right ends of the cleaning tank 1. A partition 42 is installed inside the drying chamber 41, an electric heating tube 43 is installed inside the drying chamber 41, a back plate 44 is installed outside the drying chamber 41, a fan mounting frame 45 is installed inside the back plate 44, and a fan 46 is installed inside the fan mounting frame 45.

[0040] The partition 42, heating element 43, back plate 44 and fan 46 are all detachable structures, with the heating element 43 located at the outer end of the partition 42;

[0041] The bottom of the left and right ends and the front and rear ends of the cleaning tank 1 are fixedly connected to the feet 2. The bottom of the front of the cleaning tank 1 is equipped with a drain pump 5. The front of the drain pump 5 is fixedly connected to a drain pipe 6. The top left end of the front of the cleaning tank 1 is fixedly connected to an auxiliary bracket 7. The top of the auxiliary bracket 7 is equipped with a main controller 8.

[0042] In actual operation, when this device is used, an inner support column 31092 of appropriate size is selected and installed according to the size of the valve body hole. The third servo motor 3107 is started to drive the bidirectional screw 3106 to rotate, which drives the sliding block 3109 to move in opposite directions, clamping the valve body on the inner support column 31092. The first servo motor 315 controls the screw 313 to rotate, which drives the slider 316 to descend. With the help of the electrically controlled telescopic column 319, the valve body is lowered into the cleaning tank 1 for cleaning. The second servo motor 3102 drives the rotating plate 3104 and the bottom assembly to rotate, which enhances the contact area between the valve body and the cleaning liquid. The whole system adopts automatic control, which can quickly and continuously clean the ball valve body and improve production efficiency.

[0043] After the valve body enters the cleaning tank 1, liquid is first drawn in by the liquid pump 326, and cleaning fluid is sprayed onto the valve body surface through the auxiliary cleaning nozzle 328. Then, the valve body descends into the bottom of the cleaning tank 1. The ultrasonic generator 322 works in conjunction with the adhesive ultrasonic transducer 323 to release ultrasonic waves into the cleaning tank 1, performing ultrasonic cleaning on the valve body. This ultrasonic cleaning can penetrate deep into the valve body's tiny gaps, holes, and complex structures, removing impurities in areas that are difficult to reach by traditional methods, ensuring the cleanliness of the valve body surface. This is highly beneficial for improving the valve body's sealing performance and service life. Ultrasonic cleaning is achieved by transferring energy through a liquid medium, without requiring direct contact with the valve. This method avoids scratches or damage to the valve body surface that may be caused by mechanical contact, making it particularly suitable for ball valve bodies with high surface quality requirements. It significantly improves the cleaning efficiency of the device for ball valve bodies, reducing the need for manual cleaning. Ultrasonic cleaning is highly efficient, completing the cleaning process in a short time. Furthermore, because its energy is concentrated in the cleaning fluid, it consumes relatively less energy compared to some traditional cleaning methods, such as soaking or manual wiping, resulting in better energy savings. Using water-based cleaning fluid as the medium in conjunction with ultrasonic cleaning effectively reduces the use of organic solvents, lowering environmental pollution. Moreover, the entire cleaning process eliminates the need for direct manual contact with the cleaning fluid and valve body, reducing the risk of operators coming into contact with harmful substances and improving work safety.

[0044] After cleaning, the valve body is raised, and the post-drying mechanism 4 is activated to dry the valve body. Heat is generated by the electric heating tube 43 and blown onto the valve body by the air fan 46. At the same time, the valve body is rotated by the second servo motor 3102 of the valve body fixing component, which drives the fixing frame 3105 to rotate, so that all surfaces of the valve body can be fully dried, further improving the cleaning efficiency of the device. Afterwards, the drain pump 5 is turned on and the used cleaning liquid can be recycled and processed through the drain pipe 6.
