A valve processing technology

Abstract

The invention discloses a valve processing technique. The valve processing technique comprises the following steps of a, purchasing valve body castings and forgings from outside, detecting purchased components, and carrying out repairing welding of detected castings before entering a workshop; b, hardening and tempering purchased valve rods, and carrying out turning processing, milling and drilling processing and deburring processing after the valve rods are qualified; c, putting purchased hand wheels on a hand wheel processing device, coating the surfaces of the hand wheels with paint, and putting the hand wheels coated with the paint together so as to facilitate assembling and use; d, detecting purchased sealing parts and fasteners, and putting the qualified sealing parts and fasteners in a storehouse for later use; e, assembling all the parts together to form valve products; and f, detecting assembled valves, packaging qualified valves and delivering the qualified valves out of a factory.

Description

technical field [0001] The invention belongs to the technical field of valve processing, and in particular relates to a valve processing technology. Background technique [0002] 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 can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. [0003] The finished valve is assembled by multiple parts. Before the valve is assembled, each part needs to be processed separately, including the painting operation of the hand wheel. The commonly used hand wheel painting is generally done by dipping paint, but the hand wheel The diameter of the through hole is the same as the diameter of the threaded rod. If the diameter of the handwheel is reduced after painting, th...

Problems solved by technology

[0003] The finished valve is assembled by multiple parts. Before the valve is assembled, each part needs to be processed separately, including the painting operation of the hand wheel. The commonly used hand wheel painting is usually done by dipping paint, but the hand wheel The diameter of the through hole is the same as the diameter of the threaded rod. If the diameter of the handwheel is reduced after painting, the handwheel cannot be inserted into the threaded rod, which will affect the assembly operation of the valve.
