Pipe fitting connecting valve forming treatment process

Abstract

The invention relates to a pipe fitting connecting valve forming treatment process. According to the pipe fitting connecting valve forming treatment process, internal thread machining equipment is used, and the internal thread machining equipment comprises a bottom plate, a connecting column, a mounting device and a tapping device; and when the internal thread machining equipment is used for carrying out internal thread machining treatment on a three-way pipe, the specific method comprises the following steps of position adjustment, pipe fitting fixing, size adjustment, internal thread machining and pipe fitting taking-out. According to the pipe fitting connecting valve forming treatment process, after a straight pipe part of the three-way pipe is fixed through the mounting device, tappingtreatment is conducted on the inner walls of three pipe joints of the three-way pipe at the same time through the tapping device, the tapping efficiency is effectively improved, cuttings can be blownoff and cleaned in time in the tapping process, and therefore occurrence of internal thread scratches and tap chipping due to the presence of thecuttings is avoided; and in addition, the position ofthe tapping device can be adaptively adjusted according to the included angles of the three pipe joints of the three-way pipe, the application range of the pipe fitting connecting valve forming treatment process is widened, and the investment cost of manufacturers for purchasing equipment is reduced.

Description

technical field [0001] The invention relates to the field of pipe fitting processing, in particular to a forming process for pipe fitting connecting valves. Background technique [0002] The three-way valve is a control component in the fluid delivery system, which has the functions of cut-off, adjustment, flow diversion, prevention of reverse flow, pressure stabilization, diversion or overflow, etc. It can be used to control air, water, steam, various corrosive media, mud, The flow of various types of fluids such as oil, liquid metal and radioactive medium, its main structure includes three-way pipes and valves. [0003] A pipe joint with three openings is called a tee pipe, which is a kind of chemical pipe fittings, and its material is mostly stainless steel. The three-way pipe is widely used to transport liquid and gas, and its main function is to change the direction of the fluid. [0004] During the forming process of the three-way pipe, it is necessary to process the...

Problems solved by technology

[0005] (1) The main tool used to process the internal thread is a tap. Due to the high viscosity of the stainless steel material and poor chip breaking performance, it is easy to have chips scratching the thread of the pipe fitting or chipping of the tap during the tapping process, which affects the Processing efficiency and thread quality;

[0006] (2) The three-way pipe can be divided into T-shaped three-way pipe and Y-shaped three-way pipe according to the shape. When processing tee pipes with different shapes and included angles, it is often necessary to use different processing equipment, which increases the purchase cost of the manufacturer
