[0018] 1. In this utility model, the filter screen body is snap-fitted into the filter screen mounting hole of the filter screen fixing plate. The filter screen fixing plate is inserted into the connecting flange of the water meter body. The filter screen mounting hole is connected to the inside of the connecting flange, which means that the filter screen body covers the inside of the connecting flange. This allows the filter screen body to filter suspended impurities that enter the inside of the connecting flange, thereby ensuring the metering accuracy of the water meter.

[0019] 2. In this utility model, by pulling out the filter screen fixing plate and then installing the filter screen body and the movable stop ring in sequence, the filter screen body can be quickly installed on the filter screen fixing plate.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a horizontal spiral vane water meter with a water filtration structure, comprising:

[0029] The water meter body 1 is a rotor-type water meter. Both ends of the water meter body 1 are provided with connecting flanges 2. The side of the connecting flange 2 located at the inlet of the water meter body 1 is provided with a slot 3.

[0030] A filter fixing plate 4 is inserted into the slot 3, and the filter fixing plate 4 is connected to the corresponding connecting flange 2 through a fixing bolt 5. The filter fixing plate 4 has a filter mounting hole 6, which communicates with the interior of the corresponding connecting flange 2.

[0031] The filter body 7 is snapped into the filter mounting hole 6;

[0032] The filter screen mounting hole 6 is a round hole, and the axis of the filter screen mounting hole 6 coincides with the axis of the connecting flange 2. The diameter of the filter screen mounting hole 6 is larger than the inner diameter of the connecting flange 2 to prevent part of the filter screen fixing plate 4 from extending into the connecting flange 2, thereby avoiding interference with the flow of fluid.

[0033] A fixing stop ring 8 is provided on the inner wall of the filter mounting hole 6, and a fixing ring 9 is provided on the edge of the filter body 7. The fixing ring 9 is inserted into the filter mounting hole 6 and abuts against the inner wall of the filter mounting hole 6. A movable stop ring 10 is engaged in the filter mounting hole 6. The movable stop ring 10 and the fixing stop ring 8 clamp the fixing ring 9. The movable stop ring 10 abuts against the inner wall of the slot 3. The filter body 7 can be quickly installed on the filter fixing plate 4 by simply pulling out the filter fixing plate 4 and installing the filter body 7 and the movable stop ring 10 in sequence. Similarly, the restriction on the filter body 7 can be released by simply removing the movable stop ring 10 from the filter mounting hole 6, thus facilitating the subsequent replacement of the filter body 7.

[0034] The inner walls of the fixed stop ring 8, the movable stop ring 10, and the fixed ring 9 all overlap with the inner wall of the connecting flange 2 to avoid interfering with the flow of fluid.

[0035] A sealing sleeve 11 is fitted onto the filter screen fixing plate 4. The sealing sleeve 11 abuts against the inner wall of the slot 3, and the sealing sleeve 11 can ensure the sealing between the filter screen fixing plate 4 and the slot 3.

[0036] Working principle: First, when installing the filter body 7, pull the filter fixing plate 4 out of the slot 3, insert the fixing ring 9 of the filter body 7 into the filter mounting hole 6, and then insert the movable stop ring 10 into the filter mounting hole 6 to press down the fixing ring 9. Next, insert the filter fixing plate 4 into the slot 3, and fix the filter fixing plate 4 and the connecting flange 2 with the fixing bolt 5. At this time, the inner wall of the slot 3 abuts against the movable stop ring 10, and the sealing sleeve 11 on the filter fixing plate 4 abuts against the inner wall of the slot 3. The filter body 7 is located inside the connecting flange 2. Water flows from the pipe and the inside of the connecting flange 2 into the water meter body 1. The filter body 7 filters suspended impurities in the water flow, thereby ensuring the metering accuracy of the water meter body 1. Finally, after the filter body 7 is saturated, simply remove the fixing bolt 5, pull the filter fixing plate 4 out of the slot 3, and remove the movable fixing ring 9 from the filter mounting hole 6 to release the restriction of the movable fixing ring 9 on the fixing ring 9 on the filter body 7. Then, the filter body 7 can be removed and replaced.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
