In order to achieve the above object, the utility model is implemented with the following technical solutions:
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；It is equipped with first groove outside first pipe and second pipe, is equipped with the second ditch outside first flange and second flange
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 and second flange cover outside first pipe and second pipe, are bolted, and provide axial direction for pipeline
Pretightning force compresses sealing ring；Positioning sleeve is placed 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 end surface dislocation in conjunction with pipeline is arranged.
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 utility model are:
(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 is assembled using assembled, without welding, reduces the complexity of work progress, improve construction efficiency；
(3) between pipeline by positioning sleeve and flanged joint, compare threadeds connection, flanged joint installation simply, cost compared with
It is low, suitable for the pipeline being relatively large in diameter.
