Description
Technical field
The present invention relates to a kind of tee tubes, more particularly, to a kind of production technology of positive threeway of Y type.
Background technique
Tee tube is the common connecting tube of pipe-work, and traditional tee tube mostly selects the T being made of straight tube and side pipe
Type pipe, the fresh positive tee tube of Y type that can select circular arc type less, the positive tee tube of Y type refer to the central axises of three branch pipes planar phase
At 120 ° of angles between mutually.It is arc-shaped transition between branch pipe and branch pipe, no transition angle, entire three-port structure is with each branch pipe
It is substantially symmetrical about its central axis.
Notification number CN204372417U discloses a kind of tee tube, it includes an inlet pipe, two outlet pipes and a hollow ball
Body, inlet pipe and two outlet pipes are connected to sphere, and inlet pipe and two outlet pipes are circumferentially uniformly distributed, and the internal diameter of two outlet pipes is equal,
The cross-sectional area of inlet pipe is greater than the cross-sectional area sum of two outlet pipes, is provided with filter screen in inlet pipe and two outlet pipes.This reality
Uniformly and liquid can be more filtered with the novel flow for making the liquid flowed out from two outlet pipes.
Above-mentioned tee tube, which can be realized, carries out uniform cloth liquid in two outlet pipes, and this application involves the positive tee tube of Y type
It can be realized the function, and without circulation quadrangle in overall structure, more advanced in preparation process, shunting effect is more preferable.
But use the processing method of existing tee pipe fitting larger for producing the positive threeway difficulty, it not can guarantee the specification of threeway,
Corresponding processing method is designed for the positive three-port structure, reduces production difficulty, improving qualification rate is that those skilled in the art need
The project to be thought deeply.
Summary of the invention
The object of the present invention is to provide a kind of production technology of positive threeway of butt welding Y type, the positive tee tube of Y type produced is right
Good, the high production efficiency of title property, arc transition between branch pipe.
The present invention solve the above problems used by technical solution be：A kind of production technology of the positive threeway of butt welding Y type：Including
Following steps

(4) semicircle Y type bent plate pairing made from two steps (3) is welded into the positive threeway of Y type.
The corresponding Y type of the application positive threeway tool is there are three branch pipe, arc transition between two neighboring branch pipe, three branch pipes
It is in 120 ° of angles between central axis.
The material of the Y based plate is stainless steel, and specific material is 321 stainless steels, 304 stainless steels, 316 stainless steels.
Preferably, after step (3), Y type semicircle bent plate, which is carried out heating, to be made to be formed, if not heating after cold moudling
Sizing is easy to appear the phenomenon that stress is concentrated in subsequent welding process, influences to weld fastness, makes steel plate by heat-shaping
Intensity is higher, and after welding, plate shape keeps good.
Specifically, for stainless steel material, the sizing heating temperature that Y type semicircle bent plate is arranged is 1050 ± 20 DEG C.
Compared with the prior art, the advantages of the present invention are as follows：The application devises the production technology of a positive threeway of Y type,
It first passes through and is pressed and molded out Y type semicircle bent plate, then two Y type semicircle bent plate pairings are welded as a whole to obtain Y
The positive threeway of type, the structure are rotational symmetry structure, and the cloth liquid of three branch pipes is uniform.Entire process design is ingenious, yield rate
It is high.
Detailed description of the invention
