Multifunctional glue pouring structure of water meter

Abstract

The invention discloses a multifunctional glue pouring structure of a water meter. The structure comprises a filter screen, an impeller box gland, a direct-insertion base meter inductor, an inductor PCB welding plate, an elastic pressing piece, a base meter cover plate, a meter shell and a transparent outer shell. The meter shell is formed by casting. Left and right ends are respectively a water outlet end and a water inlet end. A mounting hole is formed on the upper end. The direct-insertion base meter inductor is fixedly installed on the inductor PCB welding plate, and is in a compressed state. The small movement impeller box assembly and the filter screen are installed in the meter shell. The impeller box gland, the sheet-shaped pressing ring and the metal pressing ring are sequentiallyinstalled in the installation hole from top to bottom, and the lower portion of the impeller box gland presses the small movement impeller box assembly downwards. The structure has the beneficial effects that the structure has a multifunctional glue pouring channel which can be used for pouring glue and fastening, the battery compartment is arranged outside the shell and is independently disassembled and assembled, the battery is convenient to replace, and the meter shell does not need to be opened, the battery bin is filled with the nano paste, the battery is immersed in the nano paste, andthe sealing performance is good.

Description

technical field [0001] The invention belongs to the technical field of water metering instruments, and in particular relates to a multifunctional glue filling structure of a water meter. Background technique [0002] The water flow measurement is to convert the number of rotations of the metal induction sheet on the upper part of the impeller into the water flow through the inductance of the in-line base meter, and the distance between the inductance of the in-line base meter and the metal induction sheet is the premise to ensure the detection accuracy. Usually, AB glue is used for the glue filling and sealing of the in-line base meter inductor. The method of use is to compress the in-line base meter inductor and pour it into AB glue. After solidification, the in-line base meter inductor is sealed and fixed at the same time. Because the inductance of the in-line base meter has extremely high requirements on the distance, the detection distance of the front end of the inducta...

AI Technical Summary

Problems solved by technology

[0004] For the in-line base meter inductance in the prior art, AB glue is used to seal and fix the inductance. As the ambient temperature changes, the thermal expansion and contraction of the device will cause the detection distance of the front end of the in-line base meter inductance to change to varying degrees, which directly leads to the detection Fault problem, providing a multifunctional glue filling structure for water meters
