Abstract
The utility model relates to a ward off glass anticorrosion pipeline paint finishing with nested formula connecting device. Its technical scheme is: two adjacent anticorrosion pipeline pass through the core union coupling, the center of core pipe be equipped with the thermal -insulated recess of central authorities, be equipped with two sets of rubber ring grooves in the outside of the thermal -insulated recess of central authorities, install first rubber ring and second rubber ring respectively, anticorrosion pipeline's tip be the hole enlargement structure, and the hole enlargement structure holds concentric putting together with the core certainly, installs thermal -insulated cottonly in the thermal -insulated recess of central authorities. The beneficial effects are that: firstly, can make whole anticorrosion pipeline's internal diameter not dwindle, make liquid still can steadily spend in the junction through two anticorrosion pipeline. Secondly, adopted the twice rubber ring as the sealing washer, double -deck sealed playing is progressively reduced pressure, prevents that the weld bond of liquid in the middle of getting into is regional, thirdly thermal -insulated cotton at the thermal -insulated recess internally mounted of central authorities, and like this, high temperature is to the destruction of the intraductal anticorrosive coating of core when having avoided the welding.
Description
Technical field
The utility model relates to a kind of Glassed Steel anti-corrosion pipeline paint finishing, particularly a kind of Glassed Steel anti-corrosion pipeline paint finishing nesting type connection set.
Background technique
Along with the development of national economy, the advantage of pipeline oil transportation highlights day by day.Oil transport pipeline all adopts carbon steel seamless steel pipe, vertical masonry joint electricresistance welded steel pipe and spiral weld steel pipe substantially.The laying of oil transport pipeline generally adopts built on stilts or buried two kinds of modes on the ground.But no matter adopt that mode, when metallic conduit contacts with environment, cause its surface corrosion due to generation chemical action or electrochemical action, this problem has obtained good preservative treatment.
But, at present along with yield increases, owing to adding various polymer in the process of water filling, in oil field mining liquid, water content, polymer etc. increase greatly, accelerate the corrosion of oil-field flooding, gathering line, there is heatproof problem that is low, easily aging, easy fouling in existing anti-corrosion mode and become oil extraction in oil field technique problem demanding prompt solution, also there is the problem of inefficiency in existing spraying equipment.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, a kind of Glassed Steel anti-corrosion pipeline paint finishing nesting type connection set is provided, for supporting the movement of Glassed Steel anti-corrosion pipeline, making the spraying effect of whole device good, improve spray efficiency.
Its technological scheme is: adjacent two anti-corrosion pipelines are connected by core pipe, and the center of described core pipe is provided with central heat insulation groove, is provided with two groups of aprons slots in the both sides of the heat insulation groove of central authorities, installs the first cushion rubber and the second cushion rubber in aprons slot respectively; The end of described anti-corrosion pipeline is expanding structure, and expanding structure and core pipe keep concentric sets to be combined, in the heat insulation groove of central authorities, be provided with heat insulation foam.
The first above-mentioned cushion rubber and the second cushion rubber slope angle outside.
The left and right end portions of above-mentioned core pipe is cone structure.
The beneficial effects of the utility model are: one is because the end of two anti-corrosion pipelines is expanding structure, middle employing core pipe, can make the internal diameter of whole anti-corrosion pipeline not reduce, like this, decrease the resistance of liquid, liquid still can steadily be spent in the joint through two anti-corrosion pipelines.Two is have employed twice cushion rubber as seal ring, and double-layer seal plays decompression step by step, prevents liquid from entering middle weld bond region, even if there is liquid leakage to enter, also can form metastable medium by twice cushion rubber.Three is install heat insulation foam in the heat insulation inside grooves of central authorities, and like this, when avoiding welding, high temperature is to the destruction of the anticorrosive coat in core pipe.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structural drawing of core pipe of the present utility model;
In upper figure: core pipe 8, anti-corrosion pipeline 9, first cushion rubber 8.1 and the second cushion rubber 8.2, central heat insulation groove 8.3, heat insulation foam 8.4, weld bond 8.5.
Embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
A kind of Glassed Steel anti-corrosion pipeline paint finishing nesting type connection set that the utility model is mentioned, its technological scheme is: adjacent two anti-corrosion pipelines 9 are connected by core pipe 8, the center of described core pipe 8 is provided with central heat insulation groove 8.3, be respectively equipped with two groups of aprons slots in the both sides of the heat insulation groove 8.3 of central authorities, and the first cushion rubber 8.1 and the second cushion rubber 8.2 is installed respectively in aprons slot; The end of described anti-corrosion pipeline 9 is expanding structure, and expanding structure and core pipe 8 keep concentric sets to be combined, in the heat insulation groove 8.3 of central authorities, be provided with heat insulation foam 8.4.
The first above-mentioned cushion rubber 8.1 and the second cushion rubber 8.2 slope angle outwards, make better tightness.
The left and right end portions of above-mentioned core pipe 8 is cone structure, is convenient to the installation of the anti-corrosion pipeline being provided with expanding structure.
The utility model is when pipeline and pipeline are interconnected, and installation technology is:
A) stringing: anti-corrosion pipeline is along groove word order;
B) clear up: the running-on internal surface of cleaning anti-corrosion pipeline, the embedding mouth outer surface of cleaning connecting core pipe;
C) first cushion rubber 8.1 and the second cushion rubber 8.2 be installed on core pipe 8, and brushing oiling agent: and the slope angle of the first cushion rubber 8.1 and the second cushion rubber 8.2 is outside, check the distortionless reversal phenomenon of cushion rubber, brushing cushion rubber oiling agent, wherein, core tube hub is provided with central heat insulation groove 8.3, inner installation heat insulation foam 8.4;
D) to pipe: first aligned the interface outer end at the end interface place of anti-corrosion pipeline and be plugged, the end of two anti-corrosion pipelines 9 is expanding structure, and expanding place and core pipe 8 will keep concentric, and the internal diameter of anti-corrosion pipeline is identical with core bore; Then tie suspender belt, hang up tensioning means;
E) with machinery or instrument tension, slowly core pipe 8 is pressed into the expanding place of anti-corrosion pipeline 9, until two expanding places have docked;
F) weld: after dock, carry out butt welding mouth 8.5 and carry out spot welding, fixing weld bond, then unclamps tensioning means, welds, and due to the heat insulation groove 8.3 of central authorities inner installation heat insulation foam 8.4, like this, when avoiding welding, high temperature is to the destruction of the anticorrosive coat in core pipe.
The above, be only part preferred embodiment of the present utility model, any those of ordinary skill in the art all may utilize the technological scheme correct of above-mentioned elaboration or are revised as equivalent technological scheme.Therefore, any simple modification of carrying out according to the technical solution of the utility model or substitute equivalents, belong to the greatest extent the scope that the utility model is claimed.
