Abstract

The invention discloses an intelligent internet water meter protective shell, which comprises a control end protective shell body located at the upper end and a water passing end protective shell bodylocated at the lower end, wherein the control end protective shell body and the water passing end protective shell body are both made of high-strength engineering plastic. The left half body of the control end protective shell and the left half body of the water flowing end protective shell are integrally connected to form a left half shell; the right half body of the control end protective shelland the right half body of the water passing end protective shell are integrally connected to form a right half shell; the left half shell and the right half shell are in waterproof sealing connection, and the intelligent internet water meter protective shell is light in weight, high in strength, resistant to corrosion, high temperature and solarization and low in cost.

Description

technical field [0001] The invention relates to a water meter protective shell, in particular to an intelligent Internet water meter protective shell, which belongs to the technical field of intelligent water meter shell structures. Background technique [0002] The material of the water meter shell usually includes stainless steel, brass, ductile iron, gray cast iron and aluminum alloy. The water meter shell made of stainless steel can meet the requirements of drinking water hygiene, but the cost is high; if it is made of ordinary brass It is difficult to meet the hygienic requirements of the water meter case. If the water meter case is made of tin bronze or lead-free copper, the cost is high, and resources are scarce, and outdoor installations are often stolen; ductile iron has high strength, good toughness, and strong corrosion resistance. The technical properties of tensile, bending, hardness, elongation, impact resistance and hydrostatic test are much better than gray c...
