Description
Technical Field
The invention relates to a water meter protective shell, in particular to an intelligent internet water meter protective shell, and belongs to the technical field of intelligent water meter shell structures.
Background
The shell of the water meter is made of stainless steel, brass, nodular cast iron, gray cast iron and aluminum alloy, and the shell of the water meter can meet the sanitary requirement of drinking water but has higher cost; if the water meter shell is made of the common brass, the sanitary requirement is difficult to achieve, and if the water meter shell is made of tin bronze or lead-free copper, the cost is higher, the resource is deficient, and the outdoor installation is often stolen; the nodular cast iron has high strength, good toughness and strong corrosion resistance, and the technical performance of the nodular cast iron in the aspects of tensile strength, bending resistance, hardness, elongation, impact resistance, hydrostatic test and the like is greatly superior to that of gray cast iron. At present, the water supply pipeline of the urban water pipe network in China all adopts ductile iron pipes, so that the safe operation of the water supply pipeline network and the sanitary, safe and reliable water supply are ensured. The large-diameter water meter at home and abroad adopts nodular cast iron for most parts except a small amount of copper and stainless steel. Therefore, the nodular cast iron for the large-caliber water meter shell is very timely and reasonable; because the drinking water sanitation of the iron-clad water meter can not be closed all the time, the inner part of the iron-clad water meter is not well treated by corrosion prevention, and can get rusty in a short time, thereby causing secondary pollution to the water quality. The first water outlet of the boiling water faucet is yellow rusty water, which is not only wasteful but also unsanitary, and can not meet the sanitary requirement of drinking water, and is harmful to human body, and the material is not adopted abroad. The gray cast iron meter shell has low tensile strength, poor toughness and weak corrosion resistance, is easy to break when the water meter is installed and is easy to crack when frozen in winter. When the iron-clad water meter cannot be detached for a few years for inspection, the whole water meter is rotten to be like a new one, and no one dares to drink the water after seeing the water. In addition, with the improvement of society and the improvement of living standard of people, other materials should be used to replace gray cast iron to improve the living quality of people. Moreover, the gray cast iron meter shell has low manufacturing cost, low technical content and convenient manufacture, so that garbage meters are easy to manufacture by small enterprises and individual households. Therefore, the material of the water meter shell is not suitable for gray cast iron; the aluminum alloy water meter shell is manufactured by aluminum alloy, which not only meets the sanitary requirement of drinking water, but also ensures the technical performance of the water meter, and has the advantages of beautiful appearance, difficult corrosion, easy processing, convenient transportation, stable performance, sufficient resources, durability and the like. However, the cost is still high, and therefore, new materials are needed to meet the requirements of high strength, corrosion resistance, high temperature resistance, solarization resistance and low cost.
