[0034] Method of use of the present invention:

[0035] First, adjust the size of the check valve to be cleaned, and control the oil pump 22 to work according to the diameter of the neck next to the flange at the two opening positions of the check valve (set as d1). The oil pump 22 pumps the hydraulic oil in the oil tank 23 into each oil chamber 34 through the connector 32 and the oil pipe 33, so that each ball 36 moves toward the middle until the trajectory diameter of the circle where each ball 36 is located is the same as d1. Then control the screw motor 29 to start, and the screw motor 29 drives the drain port 28 to rotate. Under the action of the threads of the drain port 28 and the two support seats 14, the two support seats 14 are driven to move closer or farther, so that the distance between the two groups of balls 36 is exactly the same as the neck next to the flange at the two opening positions of the check valve. The check valve can be supported by the two groups of balls 36. After being supported, the check valve is manually shaken. Under the action of the weight of the check valve itself and the rolling action of the balls 36, the valve cover part of the check valve can be directly opposite to the water spray assembly 30 at the bottom;

[0036] Control the electric slider 25 to drive the cleaning bucket 12 to move, so that the two cleaning buckets 12 cover the check valve flange, and the nozzle 38 points to the neck position of the flange;

[0037] After completion, the rotating motor 48 is started, and the rotating motor 48 drives the gear 47 to rotate, and the engagement of the gear 47 and the gear ring 51 drives the turntable 41 to rotate, and the turntable 41 drives each nozzle 38 to rotate together. During the rotation process, the repulsive force of the magnet block 42 on the nozzle 38 by the magnet bar 40 will change, and the torsion spring 43 is used to make the nozzle 38 swing repeatedly, and the water pump 15 pumps water from the outside, through the hose 18, the water pipe 52, the cavity in the turntable 41, and the water pipe 44, and finally sprays out from the nozzle 38. With the rotation and repeated swinging of the nozzle 38, the holes and gaps at the flange of the check valve can be well cleaned;

[0038] In addition, the water spray assembly 30 is started to flush the valve cover of the check valve through the spray head 31. During the flushing process, the check valve can be manually pushed to achieve a better cleaning effect. Due to the presence of each ball 36, the check valve can be pushed and rotated more easily.

[0039] The cleaned waste water will flow into the waste water tank 16 from the drain port 28 and the holes in the drain tank 11, and can be reused after being purified;

[0040] After one check valve is cleaned, the two cleaning barrels 12 are controlled to move away from each other, a new check valve is taken out and replaced, and then the two cleaning barrels 12 are controlled to reset, and the new check valve can be cleaned, and the cleaning of the check valve can be continued.

[0041] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology in this field to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
