Fully-sealed antimagnetic electronic water meter protection device

Abstract

The invention relates to a fully-sealed antimagnetic electronic water meter protection device. The fully-sealed antimagnetic electronic water meter protection device comprises a water pipe, a sealing cover and a top pillar, an antimagnetic electronic water meter is installed in the middle of the water pipe, and the sealing cover is arranged outside the antimagnetic electronic water meter The sealing cover seals the antimagnetic electronic water meter through a sealing mechanism. According to the full-sealed antimagnetic electronic water meter protection equipment, a first spring is a nickel-titanium alloy spring, when the temperature is 0 degree or below 0 degree, through automatic contraction of the first spring, a first connecting cover on the left side of a sealing cover and a second connecting cover on the right side of the sealing cover move towards one side of a first mounting block. Meanwhile, the first connecting cover and the second connecting cover both drive the guide rod to move in the guide rod groove, so that the moving directions of the first connecting cover and the second connecting cover are fixed conveniently, the surface of the anti-magnetic electronic water meter is sealed conveniently, and the situation that the anti-magnetic electronic water meter is frozen at the temperature below zero, and consequently metering is abnormal is avoided.

Description

technical field [0001] The invention relates to the technical field of water meter protection equipment, in particular to a fully sealed antimagnetic electronic water meter protection equipment. Background technique [0002] Most of the water meters currently used are traditional mechanical water meters, that is, the impeller drives the wheel to rotate through the gear set to complete the measurement, but the long-term wear of the gears will cause inaccurate measurement, and there is no antimagnetic structure in the head of the traditional water meter. It often happens that the measurement is abnormal due to external magnetic interference. At this time, an antimagnetic electronic water meter is needed. [0003] When the existing antimagnetic electronic water meters are in use, in order to prevent the water meters from being frozen when the temperature is below zero, most of the antimagnetic electronic water meters are sealed when the temperature is low, so the method is time...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a fully sealed anti-magnetic electronic water meter protection device to solve the problem that the anti-magnetic electronic water meter proposed in the above background technology is mostly used when the temperature is low to prevent the water meter from being frozen when the temperature is low. The electronic water meter is sealed, so the method is time-consuming and laborious, and it is difficult to implement. At the same time, it cannot be completely sealed, and the sealing performance is poor.
