Stainless steel water meter case and production process thereof

Abstract

The invention discloses a stainless steel water meter case and a production process thereof. The production process comprise a case main body production process, a water inlet end production process and a water outlet end production process; According to the production process, the case main body, the water inlet end and the water outlet end are subjected to processes such as dismantling, laser cutting, welding, stamping and extrusion forming, so that the stainless steel water meter case is not only capable of oxidation resistance, corrosion resistance and long-term use and beautiful in appearance, but also environment-friendly, non-polluting and without influence on water quality. Meanwhile, according to the production process, the whole water meter case is dismantled into a plurality ofparts which have no large curved surfaces and can be mutually connected just by laser spot welding, the manufacturing difficulty and the manufacturing cost are greatly reduced, and the product qualification rate is improved; and a valve and a valve rod are further arranged in the water meter shell, and therefore internal water flow can be automatically controlled by the valve and the valve rod.

Description

technical field [0001] The invention relates to the field of water meters, in particular to a stainless steel water meter case and a production process. Background technique [0002] In the past, the traditional water meter case in our country was mainly made by casting. Therefore, in the process of foundry casting, there will be various degrees of quality defects such as sand holes and pores, resulting in a very low pass rate of the product. In addition, the materials of the traditional water meter case are mainly metal materials such as cast gray iron, ductile iron and cast lead brass. During use, the presence of metal elements such as iron and copper will cause metal pollution in water. Moreover, the traditional casting process has problems such as complex process, high labor intensity of workers, high energy consumption, and serious air pollution. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies of the prior art, the present inv...

[0002] In the past, the traditional water meter case in our country was mainly made by casting, so in the process of foundry casting, there will be various degrees of quality defects such as sand holes and pores, resulting in a very low pass rate of the product

In addition, the materials of the traditional water meter case are mainly metal materials such as cast gray iron, ductile iron and cast lead brass. During use, due to the existence of metal elements such as iron and copper, it will cause metal pollution in the water.

Moreover, the traditional casting process has problems such as complex process, high labor intensity, high energy consumption, and serious air pollution.
