Description

Technical Field

[0001] This utility model relates to the field of water meter sealing technology, specifically to a sealing structure for water meters. Background Technology

[0002] A water meter is an instrument used to measure water flow, mostly measuring the cumulative flow. They are generally divided into two categories: volumetric water meters and velocity water meters. Water meters have been developed for nearly two hundred years. When selecting a water meter, one should first estimate the volume and range of flow used under normal circumstances, and then choose the water meter with the closest commonly used flow rate as the first choice. The internal structure of a traditional water meter can be divided into three main parts from the outside in: the casing, the sleeve, and the inner core. The casing is made of cast iron. After water exits from the inlet, it passes through the lower annular space of the casing, called the lower annular chamber. Above this annular space is the upper annular chamber, which connects to the outlet.

[0003] The specification of a sealing structure for a water meter in the prior art (publication number CN217403522U) mentions "a waterproof rubber ring base sleeve, which is fitted inside the main housing of the water meter panel. Both sides of the inner wall of the main housing of the water meter panel have reserved openings, and both sides of the waterproof rubber ring base sleeve have openings corresponding to the reserved openings; a water inlet wheel ring, which is located on the upper side inside the waterproof rubber ring base sleeve. The upper side surface of the water inlet wheel ring has multiple openings for drainage, and the upper and lower sides of the water inlet wheel ring are respectively equipped with a second waterproof ring and a first waterproof ring." However, the sealing structure in the prior art is not corrosion-resistant or waterproof, is not durable, and is difficult to assemble and disassemble for convenient later water meter maintenance, making it neither safe nor practical. Utility Model Content
