Production process of stainless steel water meter shell

Abstract

The invention provides a production process of a stainless steel water meter shell. The production process mainly comprises the following steps: processing and manufacturing of various components of the water meter shell, welding assembling, sand blasting treatment of the shell after the welding assembling is completed, installation size processing, machine core positioning groove processing, and sealing and pressure resistance pressing test process flows. By utilizing the process, the production and manufacturing of the stainless steel water meter shell can be realized, the quality of the water meter shell can be improved, meanwhile, compared with the traditional casting process, the technological process has no serious air environment pollution problem, and is beneficial to popularization and application, furthermore, in the technological process, the number of components is small, and assembling is easy to realize, so that the production efficiency of the water meter shell can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of water watch case processing and manufacturing, in particular to a production process of a stainless steel water watch case. 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; and the material of the traditional water meter case is mainly cast ash. Metal materials such as cast iron, ductile iron and cast lead brass will cause metal pollution in water due to the existence of metal elements such as iron and copper during use. 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] The purpose of the present invention is to pr...
