Machining method for multi-welding intelligent water meter shell

Abstract

The invention provides a machining method for a multi-welding intelligent water meter shell. The machining method comprises the steps that a left shell, a right shell, a steel cover, a steel cover thread, a flow dividing partition plate, an interface thread, a valve control base, a converter support and a sensor interface are prepared for standby application; the flow dividing partition plate is arranged in the cavity of the left shell and the cavity of the right shell to surround the left shell and the right shell so as to form a surrounding main body; the steel covers are hooped on a machine core opening of the enclosure main body in a threaded mode, the connector is hooped on a water inlet of the enclosure main body in a threaded mode, the valve control base is hooped on a water outlet of the enclosure main body, and the steel covers are in threaded connection; the joint of the enclosure of the left shell and the right shell is welded through laser, and then the joint of the enclosure main body and the joint of the interface thread and the valve control base are welded; the shunting partition plates in the surrounding main body are welded and fixed through a brazing furnace, and the conversion support and the sensor interface are welded to the outer side wall of the surrounding main body to form an intelligent water meter shell; the method has the advantages of convenience in processing, reduction of energy consumption, safety, sanitation, environment-friendly production process and high intelligent degree; and meanwhile, through reasonable assembly and multiple welding processes, the machined water meter shell has a higher safety standard.

Description

technical field [0001] The invention belongs to the technical field of water meter casing processing, and in particular relates to a processing method for multiple welding smart water meter casings. Background technique [0002] The current status of water meter shells generally include cast iron shells, red punched copper shells, cast copper shells, precision cast stainless steel shells and nylon shells; [0003] The molding process of the cast iron shell: firstly, the blast furnace molten iron is introduced into the decarburization furnace for decarburization treatment to obtain molten cast iron; secondly, the molten cast iron is introduced into the ladle, and alloying raw materials are introduced into the molten cast iron, and alloyed; then The alloyed cast iron liquid is introduced into the cast iron mold, cooled and demolded to obtain the cast iron, and finally machined and sprayed. [0004] The molding process of the red punching shell: when red punching, the metal ma...
