Description

Technical Field

[0001] The utility model relates to the technical field of water meters, in particular to an antifreeze type water meter. Background Art

[0002] A water meter is an instrument for measuring water flow, most of which measure the cumulative flow of water. It is generally divided into two categories: volumetric water meters and velocity water meters. The internal structure of a traditional water meter can be divided into three parts from the outside to the inside: the shell, the sleeve, and the inner core. The shell is cast from cast iron. After the water comes out of the water inlet, it passes through the lower annular space of the shell, which is called the "lower annular chamber". Above this annular space is the "upper annular chamber" which is connected to the water outlet.

[0003] In the prior art, water meters and their pipe outer walls are usually wrapped with insulation sleeves for antifreeze treatment. In order to facilitate disassembly, most of the existing insulation sleeves are designed as assembled structures, resulting in poor sealing and incomplete insulation function, which needs to be improved.
