[0039] Working principle: When in use, first, the valve seat 1 is placed on the main support 21. By using the characteristic that the inner diameter of the outlet pipe working cavity 2 will inevitably be reduced due to the partition 4 arranged in the valve seat 1 in the present invention, the position of the small brush ring 9 is adjusted in advance, and the locking slider 14 at the end of the spiral slide bar 11 far from the valve seat 1 needs to be fixed in the sliding groove 13. Then, the movable ring 22 is controlled to rotate, driving the bottom fixing seat 19 to push the brush rod 12 into the outlet pipe working cavity 2. When the small brush ring 9 contacts the partition 4 and moves along the surface of the partition 4, at this time, due to the change in the inner diameter, the spiral brush 10 is forced to retract from the original small brush ring 9. And it accumulates at the corner. At the same time, due to the fixing of the locking slider 14 at the other end, the spiral brush 10 that has not been deformed is located in the outlet pipe working cavity 2 and contacts the inner wall of the outlet pipe working cavity 2.

[0040] Then, the two motor sliders 27 are controlled to approach each other. At this time, the first runner 28 and the second runner 31 clamp the brush rod 12, and then the motor sliders 27 are controlled to force the brush rod 12 to move back and forth. Further driving the spiral brush 10 and the small brush ring 9 to polish the inner wall of the valve seat 1.

[0041] By controlling the main drive rotating shaft 35 and the drive rotating shaft 36, the two semi-circular slideways 38 and the clamping rod 33 are opened and closed in sequence, and then the brush rod 12 is sent into them. Then, the plug 40 on the mounting support plate 39 is inserted into the sliding groove 13, and at the same time, the two clamping rods 33 are controlled to close and clamp the brush rod 12. Then, the drive slider 37 is controlled to move along the inner walls of the two closed semi-circular slideways 38 to rotate the sliding groove 13.

[0042] The present invention adds the function of a rotating grinding strip. By using the self-toughness of the grinding rod and the sliding groove 13 originally used to fix the spiral brush 10, the annular cleaning brush assembly 8 can be turned inside out from the inside to the outside. The deformation generated during the process drives the spiral brush 10 and the small brush ring 9 to stir inside the valve seat 1, further enhancing the grinding ability.

[0043] In summary, for the inner wall grinding device of the refrigeration valve seat, through the mutual cooperation of the cleaning brush assembly 8, the movable ring 22, the vertical plate 23, the pushing mechanism 18, the telescopic rod 20 and the bottom fixing seat 19. When the present invention grinds the inner wall of the variable-diameter channel in the valve seat from thick to thin, the spiral brush 10 is squeezed and stays in the thick pipe, while the small brush ring 9 directly enters the thin pipe. When pulling and rotating, the inner wall of the variable-diameter pipe is ground at the same time. Compared with the traditional grinding wheel that needs to be ground in segments, the working efficiency of the present invention is higher.
