Machining method for stainless steel angle valve body

Abstract

The invention relates to the technical field of faucets, and provides a machining method for a stainless steel angle valve body. The machining method for the stainless steel angle valve body comprisesthe following steps: a. preparation for an angle valve main body: machining a surface and then drilling a horizontal water outlet hole through a numerically-controlled drilling machine, and carryingout finish machining to obtain the stainless steel angle valve main body; b. preparation for a water outlet connector: machining a surface and then chamfering the periphery of one end which is weldedto the angle valve main body, of a straight pipe connector, and carrying out finish machining to obtain the stainless steel water outlet connector; and c. welding: inserting the chamfered end of the water outlet connector into the horizontal water outlet hole of the angle valve main body to locate, integrally welding the outer surface of the angle valve main body to the periphery of the water outlet connector, and then enabling a drill bit of an oil drilling machine to stretch into the angle valve main body to cut a part which is bulged out of the inner wall of the angle valve main body, of the water outlet connector, so as to obtain the stainless steel angle valve body. According to the machining method for the stainless steel angle valve body, the problem of high overall casting cost foran existing angle valve body is solved.

Description

technical field [0001] The invention relates to the technical field of faucets, in particular to a method for processing a stainless steel angle valve body. Background technique [0002] Angle valve is an angle globe valve, which is widely used in the field of sanitary ware. The water outlet of the angle valve is at right angles to the water inlet, and the other end is equipped with a handle to control the opening or closing of the angle valve. At present, the valve body of the angle valve is usually processed by integral casting or split welding. For the integral casting of angle valves, the valve body blanks of the angle valves are first made by sand casting, and then the valve body blanks are subjected to heat treatment and surface treatment, and then the surface finish of the valve body blanks meets the design requirements through polishing, and finally the valve body and The valve core and other parts are assembled to obtain the finished angle valve. Due to the speci...

Problems solved by technology

However, the cost of laser welding for stainless steel angle valves cast by this process is high, which is not suitable for small and medium-sized enterprises, and the internal firmness of the welding between the main body of the angle valve and the joint of the angle valve is low. When it is directly sleeved on the angle valve joint, there is an external seam and the direct force acts on the weld seam to damage the welding between the angle valve body and the angle valve joint
