Light-weight stainless steel water meter shell

Abstract

The invention discloses a light-weight stainless steel water meter shell which consists of an upper shell, a lower shell and a movement, wherein the upper shell comprises a metal wrapping housing, an inner plastic cavity, O-shaped rings and a tempered glass panel, the metal wrapping housing is arranged outside the upper shell, the inner plastic cavity is formed in the upper shell, the O-shaped rings sleeve the tempered glass panel, and the tempered glass panel is arranged on the top surface of the upper shell; the lower shell comprises a metal wrapping housing, an inner plastic cavity and two knurling connection pipes, the metal wrapping housing is arranged outside the lower shell, the inner plastic cavity is formed in the lower shell, the two knurling connection pipes are arranged on two sides of the lower shell, and the movement is arranged on the lower shell; plastic rubber is injected into a groove of the inner plastic cavity of the lower shell; an opening of the inner plastic cavity of the upper shell is inserted into the groove of the inner plastic cavity of the lower shell; the upper shell and the lower shell are in sealing adhesion. The light-weight stainless steel water meter shell has the beneficial effects of high quality and low cost.

Description

technical field [0001] The invention relates to a water meter, in particular to a light stainless steel water meter casing. Background technique [0002] At present, there are six kinds of shell materials commonly used in water meters, but all of them have different shortcomings. In the application practice, they have brought many problems to users. [0003] 1. Cast stainless steel: high energy consumption and high pollution, difficult machining and high cost; [0004] 2. Brass: my country is a country that produces less copper. In order to reduce costs, many companies add lead to copper materials beyond the standard. The lead content of most brass water meters exceeds the standard, which is likely to cause blood lead poisoning in children; [0005] 3. Ductile cast iron: poor cutting performance, it will still rust and cause secondary pollution of water supply; [0006] 4. Aluminum alloy: Aluminum oxide will be produced when exposed to water, which is the main cause of Alz...

AI Technical Summary

Problems solved by technology

[0005] 3. Ductile cast iron: poor cutting performance, it will still rust and cause secondary pollution of water supply;

[0007] 5. All kinds of plastics: they will age rapidly after long-term ultraviolet radiation, thereby reducing the pressure resistance of the shell;

[0008] 6. Stretched stainless steel is a substitute for cast stainless steel. The cost is still high, and it needs to be welded. The solder joints are easy to rust, and the solder joints are easy to burst when frozen.
