STAINLESS STEEL WATER METER HOUSING BLANK AND PROCESSING METHOD, STAINLESS STEEL WATER METER HOUSING AND WATER METER

摘要

The present invention discloses a stainless steel water meter housing blank and processing method, a stainless steel water meter housing and water meter, wherein the processing method includes steps such as component disassembly, press forming, cutting, component processing, stewing and furnace welding, etc. , the point of the above method is to disassemble the machined blank into parts such as a housing male piece, a housing female piece and an inner ring, and arrange the housing male piece and the housing female piece to have a face-symmetric mirror structure, After fitting, an inner chamber structure of the water meter housing is formed, and an accommodation space for installing the water meter component is provided in the cavity; arranging the fitting relationship between the inner ring and the housing male and female pieces to be parallel or substantially parallel to a plane having a fixing hole of the inner ring and a plane having a housing opening; A housing blank is obtained by hydraulic cold forming using stainless steel as a material, and final assembly and furnace welding. The present invention is manufactured using safer stainless steel materials, has low energy consumption during processing, is environmentally friendly, and is reused after recycling, greatly reducing overall cost.
