[0050] S3. Finally, the adjusting structure 5 rotates to drive the valve body rotating structure 6 into the interior of the cleaning water tank 4, the ultrasonic cleaner cleans the outer wall of the valve, and at the same time, the internal cleaning structure 7 of the valve body enters the inner wall of the valve for cleaning.

[0051] Working principle of the present invention:

[0052] Refer to the attached specification Figure 1-6 , first, when it is necessary to clean the in-use valve body, empty the liquid in the pipeline, then assemble the valve body cleaning equipment at the bottom of the valve, then pour the cleaning liquid into the interior of the cleaning water tank 4, then make the inner wall of the valve body support ring 304 fit with the bottom ends of both sides of the valve, then remove the valve from the pipeline, install the limit ring 305 on the top of the valve body support ring 304 to fix the valve, then the motor drives the rotating rod 302 to rotate, and then the rotating rod 302 drives the internally fixed valve through the valve body support ring 304 to rotate above the cleaning water tank 4;

[0053] Start the motor, the motor drives the transmission shaft 501 to rotate, and then the transmission shaft 501 drives the valve body rotating structure 6 through the auxiliary plate 502 to align with the flanges at both ends of the valve, so that the limit groove 603 aligns with the bolt holes of the valve flange, and then push the second rotating plate 604 inward, and the second rotating plate 604 drives the limit shaft 606 to enter the interior of the limit groove 603 and insert into the bolt holes to fix the valve;

[0054] After that, the motor drives the transmission shaft 501 to continue rotating, so that the transmission shaft 501 drives the fixed valve into the cleaning liquid inside the cleaning water tank 4, and then the ultrasonic cleaner inside the cleaning water tank 4 is started to clean the inside and outside walls of the valve;

[0055] Start the motor, the motor drives the transmission gear 504, the transmission gear 504 drives the meshing driven gear 702 to rotate, the driven gear 702 drives the auxiliary shaft 701 to rotate, so that the auxiliary shaft 701 drives the spring piece 703 and the cleaning ring 704 to rotate. At the same time, the electric telescopic rod pushes the auxiliary shaft 701 to move inward, and then the auxiliary shaft 701 drives the driven gear 702 to slide on the outer wall of the transmission gear 504 and the transmission gear 504 continues to drive the meshing driven gear 702 to rotate. Then the spring piece 703 enters the inside of both ends of the valve. During the rotation of the spring piece 703, centrifugal force is generated, so that the spring piece 703 expands and pushes the cleaning ring 704 to fit with the inside of the valve to clean the inside of the valve.
