Abstract
A kind of double bend band branch pipe three-way pipe fitting of high-temperature and pressure pipeline seamless pipe, double bend is respectively set to the threeway at three sections of prying headband branch pipe road junctions with branch pipe threeway, it is curved that three sections of curved middle parts set double bend to transfer, the curved one end of double bend switching sets main elbow section, the main main elbow import of elbow section end set, the curved other end of double bend switching sets crosswise concaving head section, and crosswise concaving head section end set turns to outlet, and main elbow section one side sets branch pipe road junction；It is set up above the tube wall of main elbow section and puts integral mouth of pipe straight pipeline；The utility model is using after being integrally pressed into double bend type, double bend outside is squeezed out a branch pipe(tube) in a mold, it will not be leaked in the environment of high temperature and pressure, crack, perforate, welding is not required, reduce the repair and retubing of high-temperature high-pressure apparatus pipeline, equipment operational effect is good, it is ensured that safety in production extends the service life of pipeline.
Description
Technical field
The utility model is related to the pipe fitting of high-temperature and pressure pipeline, especially a kind of high-temperature and pressure pipeline seamless pipe it is double curved
Headband branch pipe three-way pipe fitting.
Background technology
At present, the Pipe installing of high-temperature high-pressure apparatus uses seamless pipe, it is necessary to when carrying out the curved installation of pipeline monitor,
The method generally used is two elbows to be welded together, it is necessary to during pipe branch, after one side opening of elbow duct wall with pipe
Road branch joint is welded, and since angle is easily deformed after pipe branch weld, gap is uneven between elbow, weldering
In use, seam Seepage happens occasionally the pipe branch connector connect, and maintenance rate is high, influences the normal operation of equipment
And production safety；In view of the foregoing, a kind of double bend band branch pipe three-way pipe fitting of high-temperature and pressure pipeline seamless pipe is now proposed.
Utility model content
The purpose of this utility model is to overcome the seamless pipes that the Pipe installing of existing high-temperature high-pressure apparatus uses, and need
When carrying out the curved installation of pipeline monitor, the method that generally uses is two elbows to be welded together, it is necessary to during pipe branch,
It is formed after one side opening of elbow duct wall with pipe branch weld, since angle easily becomes after pipe branch weld
Gap is uneven between shape, with elbow, and in use, seam Seepage happens occasionally the pipe branch connector of welding,
Maintenance rate is high, influences the normal operation and production safety of equipment；By reasonably designing, it is seamless to provide a kind of high-temperature and pressure pipeline
The double bend band branch pipe three-way pipe fitting of pipe fitting, after the utility model use is integrally pressed into double bend type, in a mold double curved
Head outside squeezes out a branch pipe(tube), will not be leaked in the environment of high temperature and pressure, crack, and perforate, welding is not required, and reduces high
The repair and retubing of high-temperature high-pressure apparatus pipeline, equipment operational effect are good, it is ensured that safety in production, extend pipeline uses the longevity
Life.
The utility model to achieve these goals, adopts the following technical scheme that：A kind of high-temperature and pressure pipeline seamless pipe
Double bend band branch pipe three-way pipe fitting, be by：Main elbow section, crosswise concaving head section, double bend transfer curved, main elbow import, turn to out
Mouth, branch pipe road junction, mouth of pipe straight pipeline are formed；Double bend is respectively set to three sections of prying headband branch pipe road junctions with branch pipe threeway
Threeway, it is curved that three sections of curved middle parts set double bend to transfer, and the curved one end of double bend switching sets main elbow section, main elbow section end set
Main elbow import, the curved other end of double bend switching set crosswise concaving head section, and crosswise concaving head section end set turns to outlet, main elbow section one
Side sets branch pipe road junction；
Integral mouth of pipe straight pipeline is set above the tube wall of main elbow section.
Advantageous effect：The utility model in a mold squeezes double bend outside using after being integrally pressed into double bend type
Go out a branch pipe(tube), will not be leaked in the environment of high temperature and pressure, crack, perforate, welding is not required, reduces high-temperature high-pressure apparatus
The repair and retubing of pipeline, equipment operational effect are good, it is ensured that safety in production extends the service life of pipeline.
Description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is general assembly overlooking the structure diagram；
Fig. 2 is the side structure schematic view of Fig. 1；
In Fig. 1,2：Main elbow section 1, crosswise concaving head section 2, double bend switching are curved 3, main elbow import 4, turn to outlet 5, branch pipe
Road junction 6, mouth of pipe straight pipeline 7.
Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：
Double bend is respectively set to the threeway at three sections of prying headband branch pipe road junctions with branch pipe threeway, and three sections of curved middle parts set double
Elbow switching curved 3, curved 3 one end of double bend switching set main elbow section 1, and the main main elbow import 4 of 1 end set of elbow section is double curved
Curved 3 other end of head switching sets crosswise concaving head section 2, and 2 end set of crosswise concaving head section turns to outlet 5, and main 1 one side of elbow section sets branch pipe
Road junction 6；
Integral mouth of pipe straight pipeline 7 is set above the tube wall of main elbow section 1.
