[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] See Figures 1-5This utility model provides a water meter flow performance adjustment structure, including an adjustment plate 1 and an impeller box 2. The main body of the adjustment plate 1 has evenly distributed mounting slots 101. A drive adjustment handle 102 is provided on one side of the main body of the adjustment plate 1. An adjustment boss 103 is provided below the drive adjustment handle 102. The main body of the adjustment plate 1 is sleeved on the mounting post 202 at the bottom of the impeller box 2 through the cooperation of the mounting slots 101 and the mounting buckles 201 on the mounting post 202 at the bottom of the impeller box 2. The mounting buckles 201 and the mounting slots 101 are staggered. A number of adjustment holes 204 are distributed around the bottom surface of the impeller box 2 along the circumference of the mounting post 202. The impeller box 2 is provided with a limiting groove 203 that is set at equal angles and cooperates with the adjustment boss 103.

[0024] The drive adjustment handle 102 is set on a triangular support plate on one side of the main body of the adjustment plate 1, and the adjustment boss 103 is set on the support plate at the outermost end of the other side of the drive adjustment handle 102.

[0025] The number and position of the mounting slots 101 on the circumference of the adjusting plate 1 correspond to the number and position of the mounting clips 201 on the circumference of the mounting post 202.

[0026] There are multiple support plates.

[0027] The positions of the multiple support plates correspond to the positions of the adjustment holes 204.

[0028] The main body of the adjusting plate 1 is in the shape of a ring.

[0029] The height of the ring of the main body of the adjusting plate 1 is not greater than the distance between the top of the mounting buckle 201 and the bottom surface of the impeller box 2.

[0030] The inner diameter of the ring of the main body of the adjusting plate 1 is not greater than the width of the mounting buckle 201.

[0031] Working principle: See Figures 1-5 This invention requires minimal adjustment during use. When the mounting slot 101 on the main body of the adjustment piece 1 is aligned with the mounting buckle 201 on the mounting post 202, the main body of the adjustment piece 1 can be fitted onto the mounting post 202. Then, the main body of the adjustment piece 1 is rotated to misalign the mounting buckle 201 with the mounting slot 101, thus ensuring the adjustment piece 1 remains axially fixed and does not fall off. Then, rotating the driving adjustment handle 102 rotates the adjustment piece 1 and its support. The adjustment boss 103 at the bottom of the support engages with the limiting groove 202 at the bottom of the impeller box 2, achieving precise control of the adjustment process. This allows for more accurate control of the support's coverage of the adjustment hole, facilitating precise and rapid flow adjustment.

It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the scope of protection of this utility model.

[0033] This invention comprehensively solves the shortcomings of existing technologies in water meter flow regulation, which rely on the tightness of threads to adjust the flow through the regulating hole. These methods are mechanical, inflexible, and lack consistent and accurate control. By using flexibly adjustable, evenly distributed shims to block the regulating hole, flow accuracy is controlled. This not only makes the accuracy adjustment range visible and standardized but also simplifies and flexibly improves the debugging process. For water meter production processes that require consistent accuracy to meet factory specifications, this invention significantly enhances production efficiency and product accuracy quality.
