Description

Intelligent water meter module protection box

Technical Field

The utility model relates to the technical field of water meter manufacturing, in particular to an intelligent water meter module protection box.

Background

In the actual use process of the water meter, due to various reasons, the installation position of part of the water meter is always in a low-lying ponding area, and the electric components of the water meter have extremely high requirements on water resistance and moisture resistance, so that the sealing requirement on the electronic module of the intelligent water meter is higher. In practical application, it is found that the protective box has high water vapor transmittance and moisture absorption characteristics due to the plastic material of the protective box, and the sealing ring protective layer objectively and inevitably has extremely fine leakage, so that the interior of the protective box is always in a very humid or even condensed state, and the working performance of the electronic module is influenced. At present, a sealing mode commonly adopted by a water meter electronic module is to directly seal the module by using pouring sealant, the sealing performance of the sealing mode is greatly improved, but at the same time, other defects exist in the sealing mode, such as the pouring sealant is directly contacted with an electronic circuit board, the risk of corroding electronic components exists, after the pouring sealant is solidified, the electronic circuit board can be stripped to generate gaps due to the reasons of thermal expansion and cold contraction, the protection is invalid, the electronic components are easily damaged, and the electronic module cannot be repaired after the glue is solidified.
