Abstract

The invention relates to an anti-freezing water meter, which comprises a water meter shell, a water outlet and a water inlet. The water outlet and the water inlet are formed in the left end and the right end of the water meter shell correspondingly; a metering mechanism is mounted in the water meter shell; a bottom shell is arranged at the lower end of the water meter shell and connected with thewater meter shell through a connecting piece; and an air bag is arranged in the bottom shell and communicates with an air hole in the lower end of the water meter shell. According to the anti-freezingwater meter, during using, under the low temperature condition, the water meter shell is frozen and expanded due to increase of the internal pressure, at the moment, through expansion of the air bag,the internal pressure of the water meter shell is balanced, and thus the situation of burst of the water meter shell is avoided.

Description

technical field [0001] The invention belongs to the technical field of water meters, and in particular relates to an antifreeze water meter. Background technique [0002] In today's society, water meters are commonly used water metering equipment. However, in winter, water meters are easily damaged by freezing, especially for outdoor water meters, which need to be replaced several times a year. This not only affects the normal water use of users, but also causes water supply departments. It is difficult to manage water resources and waste water resources. Contents of the invention [0003] In order to solve the problem in the prior art that the water meter is easily damaged by freezing and cannot use water normally, the present invention provides the following technical solutions: [0004] An antifreeze water meter, comprising a water meter housing, a water outlet and a water inlet, the water outlet and the water inlet are respectively arranged at the left and right ends ...
