Abstract

The invention particularly relates to an anti-freezing water meter which comprises a water meter body, wherein an auxiliary seat is fixedly connected with each of two ends of the water meter body; a measuring water pipe is arranged in the water meter body and penetrates through the auxiliary seats to reach the outer ends; a first anti-freezing device is arranged in the middle part of one side of the auxiliary seat; a water pipe is arranged at one side of the first anti-freezing device; a second anti-freezing device is fixedly connected to the surface of one end of the water pipe; and the firstanti-freezing device and the second anti-freezing device cooperate with each other to realize the heat insulation coverage on a connecting position of a water meter measuring pipe and the water pipe.

Description

technical field [0001] The invention mainly relates to the technical field of water meters, in particular to an antifreeze water meter. Background technique [0002] Water meters are instruments for measuring water flow. Most of them measure the cumulative flow of water. They are generally divided into two types: volumetric water meters and speed water meters. They originated in the United Kingdom. The development of water meters has a history of nearly 200 years. When selecting water meter specifications, Estimate the size and flow range of the flow normally used, and then select the water meter with the specification that is closest to the value as the first choice; [0003] Existing water meters are generally installed outside the house. In the cold winter, when the temperature is below zero, it is easy to freeze the measuring tube of the water meter and the connection between the water pipes, freeze, crack, burst, etc., resulting in losses. Contents of the invention ...
