Technical field
The present invention relates to technical field of pipeline construction more particularly to a kind of flange assembled heavy caliber high pressure pipeline connection dresses
It sets.
Background technology
With the progress of social development and science and technology, construction and installation industry has also obtained great development.Assembled architecture
Due to pollute small, energy conservation and environmental protection, it is efficient the features such as have been to be concerned by more and more people.Currently gradually rise.
Assembled pipeline reduces the complexity of pipeline construction process, and construction site is only needed without welding, pipe-line system
Assembled assembles, and construction efficiency is greatly improved, shortens the construction period.Pipe-line system is rationally distributed, and interface is greatly reduced in good integrity
Quantity reduces pipe-line system risk of leakage.But existing assembled pipeline generally use groove connection type, poor sealing, only
The lower pipe-line system of the pressure such as fire water is can be suitably used for, the pressure pipings system such as hydraulic pressure can not be applicable in.
Invention content
For overcome the deficiencies in the prior art, the present invention provides a kind of flange assembled heavy caliber high pressure pipeline connection dress
It sets.It is assembled using assembled, without welding, improves construction efficiency；Good airproof performance simultaneously is suitable for pressure piping system.
In order to achieve the above object, the present invention is realized using following technical scheme：
A kind of flange assembled heavy caliber high pressure assembling pipe joint, including first pipe, second pipe, the first positioning
Set, the second positioning sleeve, sealing ring, first flange and second flange；The first pipe end is equipped with seal groove, and sealing ring is placed in
In seal groove；First pipe is equipped with the second ditch with first groove, first flange is equipped with outside second pipe with second flange outside
Slot, the first positioning sleeve are equipped with the first protrusion being adapted to first groove with the second positioning sleeve, and second be adapted to second groove is convex
It rises；First flange is sleeved on first pipe with outside second pipe with second flange, is bolted, and provide axial direction for pipeline
Pretightning force compresses sealing ring；Positioning sleeve is positioned in groove by its protrusion and pipeline and flange is located by connecting.
The first pipe is identical as second pipe internal-and external diameter, and flange faying face is arranged with pipeline combination end surface dislocation.
First positioning sleeve is identical as the second locating sleeve structure, is dissection type annulus set, and each section is bolted,
Form annulus set.
The beneficial effects of the invention are as follows：
(1) it is equipped with seal groove, is compressed sealing ring by pipe end, good airproof performance, assembled pressure piping is suitable for
System；
(2) it uses assembled to assemble, without welding, reduces the complexity of work progress, improve construction efficiency；
(3) between pipeline by positioning sleeve and flanged joint, compare threaded connection, flanged joint installation is simple, cost compared with
It is low, suitable for the pipeline being relatively large in diameter.

Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings：
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of flange assembled heavy caliber high pressure assembling pipe joint, including first pipe 1,
Second pipe 2, the first positioning sleeve 3, the second positioning sleeve 4, sealing ring 5, first flange 6 and second flange 7.
The internal diameter of the pipeline and outer diameter all same of first pipe 1 and second pipe 2, first pipe 1 and 2 outside of second pipe are equal
Equipped with first groove 9, the end of first pipe 1 is equipped with seal groove compatible with sealing ring 58.
As shown in Figure 4, Figure 5, first flange 6 is identical with 7 structure of second flange, by ring flange 15 and 16 two parts structure of sleeve
At 16 outside of sleeve is equipped with second groove 10, and ring flange 15 is flange arrangement, and 6 are evenly distributed on ring flange 15 for being bolted
Bolt hole.
As shown in Figure 6, Figure 7, the first positioning sleeve 3 is identical as 4 structure of the second positioning sleeve, is segment bounds annulus set, by upper fixed
Position set 13 is formed with lower 14 two parts of positioning sleeve, and upper positioning sleeve 13 is equipped with bolt hole with lower positioning sleeve 14, and upper positioning sleeve 13 is under
