Anti-freezing water meter

Abstract

The invention relates to the technical field of flow statistics accessory devices, in particular to an anti-freezing water meter which is simple in structure, prevents the water meter from being frostbitten and improves use reliability. The anti-freezing water meter comprises a water meter body, the front side and the rear side of the water meter body are communicated with a water inlet pipe and a water outlet pipe respectively, and flange plates are both arranged on the water inlet pipe and the water outlet pipe. The anti-freezing water meter also comprises a box body, a front inserting plate, a rear inserting plate, a front bolt and a rear bolt, a cavity is formed in the box body, and the top of the box body is communicated with an opening; the front side wall and the rear side wall of the box body are communicated with a front transition opening and a rear transition opening respectively, the front transition opening and the rear transition opening are communicated with the opening, and the bottoms of the front transition opening and the rear transition opening are both arc-shaped; the front transition opening and the rear transition opening are both communicated with the top of the box body, front clamping grooves communicated with the top of the box body are both formed on the inner left side wall and the inner right side wall of the front transition opening correspondingly, the bottom of the front inserting plate is in an arc shape, and front inserting blocks are both arranged on the left side wall and the right side wall of the front inserting plate correspondingly.

Description

technical field [0001] The invention relates to the technical field of flow statistics accessory devices, in particular to an antifreeze water meter. Background technique [0002] As we all know, a water meter is a device used to count the cumulative amount of water, and it has been widely used in the field of flow statistics; the existing water meter includes a water meter body, and the front and rear sides of the water meter body are respectively connected with water inlet pipes And the water outlet pipe, the water inlet pipe and the water outlet pipe are all provided with flanges; when the existing water meter is used, the water meter body is fixed on the water pipe through two sets of flange plates, and the water meter body performs statistics on the water accumulation; the existing water meter During the use of the water meter, it was found that the body of the water meter is likely to be damaged by freezing in areas with low temperature, and the reliability of use is l...
