Embodiment Construction

[0011] A method for manufacturing a Y-shaped valve body, comprising the steps of:

[0012] 1) Take the metal pipe and cut out a section of the main pipe, and then cut out a through hole communicating with the inside of the main pipe on the side of the main pipe;

[0013] 2) Turn one end of the main pipe out of the thread;

[0014] 3) Take the metal pipe and cut off a section of branch pipe obliquely;

[0015] 4) The through hole of the main pipe and the oblique cut of the branch pipe are heated at the same time and quickly fitted to make them combined;

[0016] 5) Use spot welding to process the joint between the main pipe and the branch pipe in step 4. Guaranteed bonding to prevent cracking.

Abstract

A method for manufacturing a Y-shaped valve body, comprising the following steps: 1) cutting out a section of main pipe from a metal pipe, and then cutting out a through hole communicating with the inside of the main pipe on the side of the main pipe; 2) threading one end of the main pipe; 3) Take the metal pipe and cut off a section of branch pipe obliquely; 4) The through hole of the main pipe and the oblique cut of the branch pipe are heated at the same time to quickly fit them together; 5) The joint between the main pipe and the branch pipe in step 4 is treated by spot welding. Guaranteed bonding to prevent cracking.

Description

technical field [0001] The invention relates to a method for manufacturing a Y-shaped valve body. Background technique [0002] Due to the specific structure and shape of the special-shaped valve body, it is usually made by casting process. If a small amount of product is required, the practical casting process will lead to a significant increase in production costs. On the other hand, the casting process needs to melt the metal, destroying the internal structure of the metal and making the metal brittle. Contents of the invention [0003] In order to overcome the deficiency that the existing special-shaped valve body can only adopt casting process due to the specific structure and shape, the invention provides a manufacturing method of a Y-shaped valve body. [0004] The technical solution of the present invention to solve its technical problem is: a kind of manufacturing method of Y-shaped valve body, comprises the following steps: [0005] 1) Take the metal pipe and ...
