Water meter housing

Abstract

A water meter housing is provided including a meter body (1), a water inlet pipe (2), a water outlet pipe (3), and a movement positioning ring (4). The meter body (1), the water inlet pipe (2), and the water outlet pipe (3) are formed by punching steel tubes. The lower end of the meter body (1) forms a circular arc-shaped shrink ring (6), and is provided with a water inlet (7) and a water outlet (8) on both sides. The neck is punched to form a ring-shaped constriction port (9) on the outer wall of the meter body (1). An inner convex ring (10) is formed in the inner wall. A horizontal convex ring (11) is formed through a flange. A round steel plate (12) is welding to a lower port (5) as the bottom of the housing. The upper end is provided with port external threads (13). The outer ends of the water inlet pipe (2) and the water outlet pipe (3) are provided with external threads (19). The inner ends of the water inlet pipe (2) and the water outlet pipe (3) are provided with arc-shaped openings (14) by laser cutting, which are respectively welded to the outer surface where the water inlet (7) and the water outlet (8) are located. The water meter housing of the invention uses thin material, is light in weight and low in manufacturing cost, and meets environmental protection requirements.

Description

technical field [0001] The invention belongs to the technical field of water meter manufacturing, and in particular relates to a water meter shell formed by stamping and welding by adopting steel pipes or steel plates. Background technique [0002] At present, most of the water meter shells on the market are made of nodular cast iron or brass casting; due to the casting molding process, the shell thickness is relatively large and the weight is heavy, and casting defects such as pores and shrinkage are prone to occur, resulting in low production efficiency ; Cast iron is easy to rust, which affects water quality, and the cost of brass casting is very high; at the same time, there are more waste gases in the production process, which has a great impact on the environment and human body. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a water meter casing that is formed by stamping and welding steel pipes or steel p...
