Abstract
The invention discloses a carbon fiber cable for heat preservation of a novel pipeline. The carbon fiber cable comprises two carbon fiber hearing wire cables and one power wire cable, wherein the two carbon fiber hearing wire cables and the power wire cable are stranded in a mode of a shape like a Chinese character 'pin', and a tension-resisting core wire is arranged at the center of the two carbon fiber hearing wire cables and the one power wire cable. When the carbon fiber hearing wire cables and the power wire cable are tied on a plastic pipeline, the plastic pipeline begins to be lengthened due to thermal expansion, friction coefficients of the carbon fiber hearing wire cables and the power wire cable adhered to and tied with the pipeline are very small due to a lubricating oil film on the surfaces, and the oily sliding friction effect is played. Therefore, the extension tension produced by the plastic pipeline due to the thermal expansion is not completely acted on the carbon fiber hearing wire cables and the power wire cable, and accordingly the problem of local tensile failure or whole tensile failure is effectively solved.
Description
Technical field
The present invention relates to a kind of carbon fiber cable, especially a kind of novel pipeline insulation carbon fiber cable.
Background technology
With carbon fiber as electric heating material, outer with plastics or rubber etc. as insulating material, can produce carbon fiber heating cable, if at carbon fiber side plain conductor arranged side by side, can produce carbon-fiber electric tracing band, usually can use the various paper of the adhesive tape with glue or with the strip material of glue, carbon fiber heating cable or carbon-fiber electric tracing band not tied up and applied the pipeline scholar, this series products is widely used in, in the anti-freezing and heat-insulating of various pipelines, comprising various plastic conduits.Because the coefficient of thermal expansion and contraction of plastic conduit is usually larger, and the coefficient of thermal expansion and contraction of carbon fiber heating cable or carbon-fiber electric tracing band is smaller, the not identical or different step of coefficient of thermal expansion and contraction between the two, so in the process of normal operation, plastic conduit is due to the former thereby heat expansion elongation of being heated, plastic conduit is in elongation, will produce pulling force to tying up the carbon fiber heating cable or the carbon-fiber electric tracing band that apply on this pipeline, when this pulling force acts on carbon fiber heating cable or carbon-fiber electric tracing band for a long time, just may cause the fatigability part to break or all break to carbon fiber or metallic conductor, thereby cause the various faults such as fire, affected the normal use of product.
Summary of the invention
The invention provides a kind of novel pipeline insulation and use carbon fiber cable, coefficient of safety is high, long service life.
For addressing the above problem, the present invention adopts following technical scheme: a kind of novel pipeline insulation carbon fiber cable, comprise two carbon fiber heating cables and a power cable, it is stranded that its two carbon fiber heating cables and power cable are isosceles triangle, in the middle of two carbon fiber heating cables and a power cable, is provided with a tension heart yearn; Described carbon fiber heating cable and power cable are wrapped with inner sheath, and inner sheath is outside equipped with the nylon yarn braid, and the nylon yarn braid is outside equipped with oversheath; Described oversheath one side is provided with pipeline, and oversheath crosses adhesive tape with device for cleaning pipeline or insulation plasticity water blocking tape is connected.
Optimize, carbon fiber cable is used in above-mentioned novel pipeline insulation, and its carbon fiber heating wire cable wrap is drawn together the carbon fiber inner core, and the carbon fiber inner core is outside equipped with the synthetic mica heat-conducting layer, and the synthetic mica heat-conducting layer is outside equipped with the pyrocondensation insulating barrier.
Optimize, above-mentioned novel pipeline insulation uses carbon fiber cable, its power cable to comprise the stranded inner core of copper wire, and the stranded inner core of copper wire is wrapped with the grease insulating barrier.
The present invention is tied up while applying on plastic conduit when carbon fiber heating cable and power cable, when plastic conduit starts to elongate due to heat expansion, tie up with this pipeline carbon fiber heating cable and the power cable that applies and stick together, because there is one deck lubricating oil film on its surface, coefficient of friction is especially little, and the sliding friction effect of formation oiliness, so plastic conduit just can not all act on carbon fiber heating cable and power cable because of the elongation pulling force that heat expansion produces, thereby effectively solved the local problem of breaking or all breaking, the present invention has realized that coefficient of safety is high, the purpose of long service life.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below with best embodiment, the present invention is described in detail
.
As shown in Figure 1, the present invention is a kind of novel pipeline insulation carbon fiber cable, comprise two carbon fiber heating cables 1 and a power cable 2, it is stranded that its two carbon fiber heating cables 1 and power cable 2 are isosceles triangle, in the middle of two carbon fiber heating cables 1 and a power cable 2, is provided with a tension heart yearn 3; Described carbon fiber heating cable 1 and power cable 2 are wrapped with inner sheath 4, and inner sheath 4 is outside equipped with nylon yarn braid 5, and nylon yarn braid 5 is outside equipped with oversheath 6; Described oversheath 6 one sides are provided with pipeline 7, and oversheath 6 is connected by adhesive tape or insulation plasticity water blocking tape with pipeline 7.Carbon fiber heating cable 1 comprises carbon fiber inner core 11, and carbon fiber inner core 11 is outside equipped with synthetic mica heat-conducting layer 12, and synthetic mica heat-conducting layer 12 is outside equipped with pyrocondensation insulating barrier 13.Power cable 2 comprises the stranded inner core 21 of copper wire, and the stranded inner core 21 of copper wire is wrapped with grease insulating barrier 22.The present invention is tied up while applying on plastic conduit when carbon fiber heating cable and power cable, when plastic conduit starts to elongate due to heat expansion, tie up with this pipeline carbon fiber heating cable and the power cable that applies and stick together, because there is one deck lubricating oil film on its surface, coefficient of friction is especially little, and the sliding friction effect of formation oiliness, so plastic conduit just can not all act on carbon fiber heating cable and power cable because of the elongation pulling force that heat expansion produces, thereby effectively solved the local problem of breaking or all breaking, the present invention has realized that coefficient of safety is high, the purpose of long service life.
Finally it should be noted that: obviously, above-described embodiment is only for example of the present invention clearly is described, and is not the restriction to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all execution modes.And the apparent variation of being amplified out thus or change are still among protection scope of the present invention.
