Angle valve body manufacturing method

Abstract

The present invention proposes a method for manufacturing an angle valve body with simple manufacturing process and low production cost, including: 1) forming steps of the water inlet pipe: a, selecting a pipe material with suitable hardness and flexibility, and cutting the pipe material into desired The required length is obtained for the body of the water inlet pipe; b. Form a limit placing platform at one end of the water inlet pipe for installing the valve core. 2) The forming steps of the valve core installation pipe: a. Select a pipe material with suitable hardness and flexibility , cut the pipe into the required length to obtain the valve core installation pipe body; b, car a side hole for installing the side outlet pipe on one side of the valve core installation pipe; 3), the forming steps of the side outlet pipe: a. Select the pipe material with suitable hardness and flexibility, cut the pipe material into the required length to obtain the side outlet pipe body; 4), seamlessly weld the water inlet pipe to the lower part of the valve core installation pipe, and enter 5 ), thread the side outlet pipe into the side hole of the valve core installation pipe and seamlessly weld the side outlet pipe on the side hole of the valve core installation pipe.

Description

technical field [0001] The invention relates to the manufacture of plumbing valves, in particular to a method for manufacturing an angle valve body. Background technique [0002] Angle valve is an angle globe valve, which has the characteristics of simple flow path, small dead zone and eddy current zone, small flow resistance, etc., is not easy to be blocked, and has self-cleaning performance. It can even be applied to various occasions of high viscosity, suspended solids and granular fluids. The flow direction is generally bottom-in and side-out. The known angle valve includes a valve body which is arranged on the upper side of the valve body to open and close the spool. Side outlet pipe on the side. It is used on the pipeline to connect the internal and external water outlets, adjust the water volume or close the waterway; the known angle valve body mainly has the following defects: [0003] 1. The shell of the existing angle valve is generally formed by integral casti...

AI Technical Summary

Problems solved by technology

[0003] 1. The shell of the existing angle valve is generally formed by integral casting of sand cores. Not only the molding mold is complex, but also large-scale production equipment such as furnaces are required. The manufacture of sand molds is also troublesome, the cost of mold opening is high, the manufacturing process is complicated, and the production cost is high. Produce waste slag and furnace exhaust gas, causing serious pollution to the environment
