After welding, weld bond 5 is isolated with anticorrosive coat 3 by heat-insulating and sealing chamber 4, is possible not only to make solder joint remote by this structure
From anticorrosive coat 3, and isolated by heat-insulating and sealing chamber 4, can effectively prevent the heat damages anticorrosive coat 3 during welding, and
Heat non-rectilinear transmits, and can reduce conduction of heat, prevents from further damaging anticorrosive coat 3, so not only increases the anti-corrosive properties of pipeline
Energy and sealing property, also improve the linking intensity at pipe joint, to meet at sufficiently large intensity of pressure lower seal simultaneously.
Embodiment one:
Joint 2 is fixedly installed on the outer surface of pipeline body 1, and described anticorrosive coat 3 is arranged on the interior of adjacent two pipeline bodies
On wall.Wherein, joint includes connecting portion 10 that internal diameter is identical with pipeline body 1 external diameter and the insulation part more than connecting portion diameter
11, described insulation part 11 be arranged in parallel with pipeline body 1, and the insulation part 11 of adjacent two joints welds together.So pass through
The welding of two insulation part 11 can make solder joint away from anticorrosive coat 3, and is isolated by heat-insulating and sealing chamber 4, can effectively prevent
Heat damages anticorrosive coat 3 during welding, and the transmission of heat non-rectilinear, can reduce conduction of heat, prevents from further damaging anticorrosive coat
3, so not only increase antiseptic property and the sealing property of pipeline, also improve the linking intensity at pipe joint simultaneously, with
Meet at sufficiently large intensity of pressure lower seal.
The end of adjacent two pipeline bodies 1 is provided with the liner flange 9 extended along anticorrosive coat 3, adjacent two joints 2 interior
The corresponding contact of lining flange 9, forms the heat insulation close of annular by liner flange 9 and the insulation part 11 of two joints 2 and pipeline body 1
Envelope chamber 4.It is possible to prevent when filling charges 8 in heat-insulating and sealing chamber 4 to leak to anticorrosive coat by the corresponding contact of liner flange 9
In 3, improve sealing.
When specifically installing, pipeline body 1 is first welded with joint 2, makes the inwall of joint 2 and the outer surface of pipeline body 1
Fixing, then the inwall upper berth at pipeline body 1 sets anticorrosive coat 3, and outwards overturns formation liner in the end of pipeline body 1 and turn over
Adjacent two joints 2 are alignd by limit 9, make the liner flange 9 extruding contact of pipeline body 1 end, and weld insulation part 11
Connecing, wherein, weld bond 5 is that the welding of adjacent two insulation part 11 is formed, after weld, insulation part 11 and pipeline body 1 formed every
Heat seal chamber 4, is filled charges 8 in heat-insulating and sealing chamber 4 by hole 6, seals such as glue class etc., then blocked by sealing
7 plugging holes 6, prevent from revealing.
Embodiment two:
With reference to Fig. 2, above-mentioned joint 2 is fixed on the internal diameter of the end of pipeline body 1, the internal diameter of joint 2 and pipeline body 1
Unanimously, pipeline body 1 is equipped with anticorrosive coat 3 on the inwall of joint 2, anticorrosive coat 3 for be arranged on interior tube inner surface and end face and
Adjacent two joints 2 are welded by the continuous structure of inner surface of pipeline, can be coupled together by two pipeline bodies 1.
Joint includes being made up of inner core 21 and the urceolus 22 coaxial with inner core 21, and one end of urceolus 22 is connected with inner core 21
Connecing, the urceolus 22 of the joint of adjacent two pipelines welds together, and forms annular heat annular seal space between inner core 21 and urceolus 22
4.Owing to urceolus 22 is away from anticorrosive coat 3, solder joint so can be made away from anticorrosive coat 3, do not damage anticorrosive coat 3, it is ensured that antiseptic effect.
Meanwhile, anticorrosive coat 3, when laying, can extend at the inner core 21 of adjacent two joints 2 and form liner flange
9, i.e. two liner flange 9 wrap the end face of inner core 21, and liner flange 9 correspondence of adjacent two joints 2 contacts, and i.e. two
While the inner core 21 of individual joint 2 is shorter than urceolus 22, so welding urceolus 22, the liner flange 9 between two inner cores 21 can be made
It is in close contact, prevents from leaking in anticorrosive coat 3 when filling charges 8 in heat-insulating and sealing chamber 4, improve sealing.
Wherein, the axial cross section of described inner core 21 and urceolus 22 is U-shaped or H-shaped structure.Certainly, can as required, also
Can be other structures that can realize buffer action.
From the foregoing, it will be observed that the weld bond 5 of joint 2 is away from anticorrosive coat 3, and the structure with isolating seal chamber 4 belongs to protection
Within the scope of.
When specifically installing, pipeline body 1 is first welded with joint 2, make the inwall of joint 2 put down with the inwall of pipeline body 1
After the most fixing, set anticorrosive coat 3 on the inwall upper berth of pipeline body 1 and joint 2, and in the end of inner core 21 outwards overturns formation
Lining flange 9, by adjacent two joints alignment, makes the liner flange 9 extruding contact of inner core 21 end, and welds urceolus 22
Connecing, wherein, weld bond 5 is that two urceolus 22 welding are formed, and after having welded, squeezes between urceolus 22 and inner core 21 and two inner cores 21
The liner flange 9 of pressure forms heat-insulating and sealing chamber 4, fills charges 8 by hole 6, as glue class etc. carries out close in heat-insulating and sealing chamber 4
Envelope, then by sealing blocking 7 plugging holes 6, prevents from revealing.
This utility model is rational in infrastructure, can reduce conduction of heat by the heat-insulating and sealing chamber 4 of annular, can effectively prevent anticorrosion
The damage that causes of layer, sealing and antiseptic property are good, can effectively prevent pipe leakage, extend pipeline service life, and can subtract
Little entire outer diameter, it is simple to construction.
This utility model is not limited to above-mentioned embodiment, in the ken that those skilled in the art are possessed,
Can also make a variety of changes on the premise of without departing from this utility model objective, the content after change still falls within this utility model
Protection domain.
