The invention relates to the technical field of water meters, in particular to a high-precision antifreeze water meter and a high-precision antifreeze treatment method for the water meter, wherein the high-precision antifreeze water meter includes a pressure relief structure inside the watch core, and the pressure relief structure The inside is filled with elastic material, and the surface of the pressure relief structure is provided with a pressure relief hole, and the liquid inside the watch core is guided into the pressure relief structure through the pressure relief hole after the frozen volume expands. The high-precision antifreeze water meter provided by the present invention can prevent damage to the structure such as the internal watch core and the watch case, and can also prevent the deformation of the elastic material due to the expansion and extrusion of ice cubes, resulting in changes in the shape and size of the inner cavity of the water meter, thereby affecting the water flow. characteristics, at the same time, it can detect the flow of weak water flow, ensure the measurement accuracy of the water meter, reduce the waste of manpower and material resources, and has extremely high industrial value and application prospects.
Description
technical field [0001] The invention relates to the technical field of water meters, in particular to a high-precision antifreeze water meter and a high-precision antifreeze treatment method for the water meter. Background technique [0002] With the continuous development of industrial economy and urban scale, water meters are being installed and used more and more widely in industrial and residential life as instruments for measuring water flow. The water meter on the market mainly drives the impeller to rotate through the water flow, which drives the gear on the counter to rotate to measure the water consumption. [0003] As the existing water meter does not adopt any anti-freezing measures to protect the water meter, when the extremely low temperature weather hits, the water medium in the water meter turns into an ice medium, so that the pipelines at both ends are frozen, and the water in the water meter turns into ice. The resulting volume expansion pressure is quickly...
