Summary of the invention
Poor for solving existing petroleum pipeline heater heat insulation effect, the defects such as working life is short, spy of the present invention provides insulation corrosion resistant oil transport pipeline.
Technological scheme of the present invention is as follows:
Be incubated corrosion resistant oil transport pipeline, comprise two L-type support be oppositely arranged, be arranged on base between L-type support, also comprise the pipeline be fixed on base, pipeline comprises the zone of heating being ring, isolation layer, the protective layer that set gradually from the inside to the outside; Zone of heating is the cirque structure of hollow, also comprises the snakelike groove offered around zone of heating cavity inner wall, also comprises the heating wire be arranged in snakelike groove.
Further, also comprise the supporting base be fixed on base, the upper-end surface of supporting base has semi-circular recesses; Described pipeline is placed in semi-circular recesses; Also comprising three is separately positioned on bottom semi-circular recesses protruding with the cambered surface in left and right sides, and cambered surface projection is made up of elastic material, described pipeline and cambered surface projection contacts.
Further, described isolation layer is bitumen layer.
Further, the glass wool be filled in protective layer is also comprised.
Further, described L-type support is made up of horizontal segment and vertical section, and vertical section vertical-horizontal section is upwards arranged, and vertical section upper surface has cylindrical body groove, and cylindrical body groove inner wall is provided with internal thread; Also comprise the screw rod being threaded connection and being arranged in cylindrical body groove; Also comprise the connecting rod be connected with screw rod by bearing, the side of vertical section has slit, and base is fixed on connecting rod through slit.
In the present invention, be arranged on heating wire in zone of heating cavity petroleum streams through pipeline time, can to petroleum, snakelike groove serves the effect of fixing heating wire.And snakelike groove is convenient to heating wire to be fixed on comparatively uniformly on the inwall of petroleum pipeline, ensure that heating effect.To be separately positioned on bottom semi-circular recesses internal surface and the arc convex of the left and right sides serves firm effect to pipeline, what it is such that petroleum pipeline can be comparatively stable is arranged in supporting base, avoids laying shakiness or occurring the phenomenon that pipeline is distorted.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of heating and heat-insulating type petroleum pipeline;
Fig. 2 is the structural representation of zone of heating internal surface;
Component title wherein corresponding to reference character is as follows:
1-L type support, 2-base, 3-pipeline, 4-zone of heating, 5-isolation layer, 6-protective layer, the snakelike groove of 7-, 8-supporting base, 9-semi-circular recesses, 10-cambered surface is protruding, 11-screw rod.
