The invention relates to the technical field of water meters and particularly relates to a high-precision anti-freezing water meter and a water meter high-precision anti-freezing treatment method. According to the high-precision anti-freezing water meter, a pressure relief structure is arranged in a meter core, the pressure relief structure is filled with an elastic material, pressure relief holesare formed in a surface of the pressure relief structure, and liquid in the meter core is guided into the pressure relief structure through the pressure relief holes after being frozen and expanded in volume. The high-precision anti-freezing water meter is advantaged in that structures such as meter cores and the like and meter casings can be prevented from being damaged, the elastic material canbe prevented from deforming due to expansion and extrusion of ice blocks to change the shape and size of an inner cavity of the water meter and influence water flow characteristics, moreover, the flow of a weak water flow can be detected, measurement precision of the water meter is guaranteed, waste of manpower and material resources is reduced, and extremely high industrial value and applicationprospects are achieved.
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...
