Description

Technical Field

[0001] The utility model relates to the technical field of water meter equipment, in particular to an improved rotor-type plastic shell water meter. Background Art

[0002] As a core component in modern water systems, rotor-type plastic water meters accurately measure water flow by using water flow to drive the rotor to rotate. They are suitable for a variety of environments and application scenarios and have significant advantages in initial investment and operating costs. However, during long-term use, rotor-type plastic water meters may encounter water leakage problems, which not only affects the accuracy of the water meter but may also lead to waste of water resources.

[0003] Compared to traditional water meters, the plastic casing of rotary vane water meters has limitations in terms of corrosion resistance and structural stability. Furthermore, in harsh environments, the flat filter screens used in existing water meters create significant resistance. Excessive impurities in the water can cause the screen to be unable to effectively prevent impurities from entering the meter, thus failing to protect the meter's movement and shortening the meter's lifespan.

[0021] For descriptive purposes, this disclosure may use spatially relative terms, such as "below," "beneath," "beneath," "below," "above," "upper," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another component(s) as illustrated in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over, a component described as "below" or "beneath" another component or feature would then be oriented "above" the other component or feature. Thus, the exemplary term "below" can encompass both "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and as such, the spatially relative descriptors used herein should be interpreted accordingly.
