Abstract
The utility model discloses a kind of one-piece type insulating joint, it is characterized in that, comprise: downstream conduit, upstream conduit and outer sleeve, the inner end of downstream conduit and the inner end of upstream conduit are formed with downstream conduit flange respectively, upstream conduit flange, downstream conduit flange is opposed with upstream conduit flange coaxial and on respective junction plane, be formed with O type groove, O type circle is placed with in O type groove, pressing plate is provided with between two O type circles, three fits tightly formation static seal, outer sleeve is enclosed within the joint of downstream conduit and upstream conduit and is welded and fixed with upstream conduit, gap between outer sleeve and downstream conduit is provided with insulation spacer.Usefulness of the present utility model is: the conduit flange of conduit and its end adopts integrative-structure, substantially increases the rigidity of insulating joint, and it is larger to bear moment of flexure; Insulation spacer, O type circle and pressing plate are outside completely isolated by downstream conduit, and not only sealing configuration is simple, and sealing, insulating properties are better, can buriedly install.
Description
Technical field
The utility model relates to a kind of insulating joint, is specifically related to a kind of one-piece type insulating joint, belongs to tube circumference part technical field.
Background technique
In order to reduce oil, petrochemical industry, gas pipeline generation electrochemical corrosion; except pipeline is carried out anticorrosion except; also need to implement cathodic protection to pipeline; and the pipe-line system implementing cathodic protection needs installing insulating joint between system outer connecting pipe road to carry out electrical insulation, avoid the loss of cathodic protection current.
But there are following problems in existing insulating joint: rigidity is more weak, and the moment of flexure that can bear is less, and insulating property are poor in actual use.
Model utility content
For solving the deficiencies in the prior art, the purpose of this utility model be to provide a kind of rigidity strong, can bear that moment of flexure is large, good insulating and the simpler one-piece type insulating joint of structure.
In order to realize above-mentioned target, the utility model adopts following technological scheme:
One-piece type insulating joint, it is characterized in that, comprise: downstream conduit, upstream conduit and outer sleeve, aforementioned downstream conduit is formed with downstream conduit flange towards one end of upstream conduit, upstream conduit is formed with upstream conduit flange towards one end of downstream conduit, downstream conduit flange is opposed with upstream conduit flange coaxial and on respective junction plane, be formed with O type groove, O type circle is placed with in O type groove, pressing plate is provided with between O type circle on downstream conduit flange and the O type circle on upstream conduit flange, two O type circles and pressing plate fit tightly formation static seal, outer sleeve is enclosed within the joint of downstream conduit and upstream conduit and is welded and fixed with upstream conduit, gap between outer sleeve and downstream conduit is provided with insulation spacer.
Aforesaid one-piece type insulating joint, is characterized in that, the outer end of aforementioned downstream conduit and the outer end of upstream conduit are respectively welded with an adapter.
Aforesaid one-piece type insulating joint, is characterized in that, aforementioned downstream conduit, gap place between upstream conduit and outer sleeve are filled with insulating encapsulating material.
Usefulness of the present utility model is:
1, the conduit flange of conduit and its end adopts integrative-structure, substantially increases the rigidity of insulating joint, and it is larger to bear moment of flexure;
2, O type circle and pressing plate fit tightly formation static seal, insulating encapsulating material, insulation spacer, O type circle and pressing plate by downstream conduit completely " isolation " outside, not only sealing configuration is simple, and sealing, insulating properties (>=10M Ω) better, can buriedly install;
3, adapter adds the length of insulating joint, effectively prevent joint because of too short with heat trnasfer Damage to insulation material in the process of pipeline welding, extend the working life of insulating joint.
Accompanying drawing explanation
Fig. 1 is the section of structure of a specific embodiment of one-piece type insulating joint of the present utility model.
In figure, the implication of reference character: 1-takes over, 2-downstream conduit, 3-outer sleeve, 4-insulation spacer, 5-insulation spacer, 6-O type circle, 7-pressing plate, 8-O type circle, 9-upstream conduit, and 10-takes over.
Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the utility model.
With reference to Fig. 1, one-piece type insulating joint of the present utility model comprises: downstream conduit 2, upstream conduit 9 and outer sleeve 3.Wherein, downstream conduit 2 is formed with downstream conduit flange towards one end of upstream conduit 9, upstream conduit 9 is formed with upstream conduit flange towards one end of downstream conduit 2, because the conduit flange of conduit and its end adopts integrative-structure, so insulating joint of the present utility model has stronger rigidity, it is larger to bear moment of flexure; Downstream conduit flange is opposed with upstream conduit flange coaxial and on respective junction plane, be formed with O type groove, O type circle 6 and O type circle 8 is placed with in O type groove, O type circle 6 on downstream conduit flange and be provided with pressing plate 7, O type circle 6 between the O type circle 8 on upstream conduit flange, O type circle 8 fits tightly formation static seal with pressing plate 7; Outer sleeve 3 is enclosed within the joint of downstream conduit 2 and upstream conduit 9, and be welded and fixed with upstream conduit 9, gap between outer sleeve 3 and downstream conduit 2 is provided with insulation spacer 4 and insulation spacer 5, due to insulation spacer 4, insulation spacer 5, O type circle 6 and pressing plate 7, by downstream conduit 2, completely " isolation " outside, so insulating joint of the present utility model not only sealing configuration is simple, and sealing, insulating properties are better, can buriedly install.
Downstream conduit 2, gap place between upstream conduit 9 and outer sleeve 3 are filled with insulating encapsulating material, further increase the sealing of insulating joint, insulating property.
As the preferred scheme of one, the outer end of downstream conduit 2 is welded with adapter 1, and the outer end of upstream conduit 9 is welded with adapter 10.The effect of adapter 1 and adapter 10 is the length of increase insulating joint, be used for avoiding joint because of too short with heat trnasfer Damage to insulation material in the process of pipeline welding, thus the working life of insulating joint can be extended.
It should be noted that, above-described embodiment does not limit the utility model in any form, the technological scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection domain of the present utility model.
