Valve manufacturing process

Abstract

The invention discloses a valve manufacturing process. The valve manufacturing process comprises the steps of (a) selecting raw materials; (b) forming materials; (c) forging: generating local or all plastic deformation on a metal blank or cast ingot under the action of pressure equipment and a tool (die) so as to obtain the prototype of a valve; (d) performing heat treatment before entering a factory: in order to satisfy the processability (such as the improvement of cutting, the reduction of stress and the increase of plasticity), heat treatment before delivery needs to be specially specified before delivery of the materials used for the valve, and different materials have different states; (e) machining in different processes including turning, milling and grinding so as to obtain a valve product; (f) performing surface hardening treatment including supersonic spray, spray welding and nitridation; (g) assembling: assembling parts and components after production into a formed valve product; (h) cleaning: putting the assembled valve in cleaning equipment, and removing residues during machining of the valve and grease during assembly; and (i) packaging and transporting: performing a series of performance detection on the valve, and packaging and transporting the qualified valve to a sales area.

Description

technical field [0001] The invention belongs to the technical field of valve processing, and in particular relates to a valve manufacturing process. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve and so on. [0003] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications. [0004] Valves can be used to control the flow of various types of fluids such as air, w...

AI Technical Summary

Problems solved by technology

The cleaning of the valve can effectively remove the residues in the process of valve processing and the grease in the assembly, etc.; the existing valve cleaning equipment cannot realize the cleaning of the assembly line, the cleaning efficiency is low, the cleaning effect is not good, and manual assistance is required in the cleaning process
