Technical field
The present invention relates to a kind of three-way pipes, more particularly, to a kind of supervisor's reducing tee and its production technology.
Background technology
Three-way pipe is the common connecting tube of pipe-work, and the three-way pipe that heavy construction is used will often use reducer tee piece
To bear pressure.Notification number CN106051352B discloses a kind of large-scale pressure pipe to the processing engineering method of reducing tee pipe fitting, adopts
Use SA3P35P91 superhigh temperature resistants pipeline as reducing tee embryo material, the outer diameter of embryo material is more than maximum in the middle part of reducing tee straight pipeline
Outer diameter, length of stock add required surplus according to the length of reducing tee straight pipeline, then blanking；Embryo material is put into preheating furnace, is waited for
Blank is taken out when preheating temperature is between 1000 DEG C -1050 DEG C, embryo material is put into compacting tool set, material embryo flatten up and down,
Full of being taken out after the molding for completing reducing tee when being bubbled with end in mold mouth to be pressed, the bubbling for being in charge of road junction is then cut away
Complete the blank of reducing tee；Increase slope cushion block in mold mouth, to inwardly curium is pressed into outside the mouth of straight pipeline and subtube
Row necking and the necking compacting repeated；The present invention alleviates the high pressure of big flow when pipeline is in controlled valve, avoid high pressure and
The damage connect to pipe is corroded, is prolonged the service life.
The processing technology of above-mentioned three-way pipe is more complex, to straight pipeline and is in charge of by the slope cushion block that is arranged in mold mouth
Inwardly curium pressure carries out the compacting of necking outside the mouth in road, and repeated multiple times compacting completes reducing tee oral area after mold closes reality
Compacting.I.e. reducing is realized by specific mold, during necking, since entire three-way pipe tube body is all in mold
, the shape of tube body is easily controllable, but the variable diameter passage in pipe is since deformation extent difference of the material into pipe then can not be accurate
Control, the poor repeatability of product.
