Patent documentation CN2689637Y discloses a kind of two-conductor line carbon fiber electric heating cable; Comprise the power lead, electric conduction of carbon fiber layer, graphite fiber external insulation layer and the metal knitted stratum reticulare that are covered with isolation layer, its structural feature is: two parallel power lead outsides that are covered with isolation layer are coated with electric conduction of carbon fiber layer, graphite fiber external insulation layer and metal knitted stratum reticulare from inside to outside successively; Two power leads are provided with the joint that connects power lead and electric conduction of carbon fiber layer at the difference end respectively.There is following deficiency in this kind carbon fiber electric heating cable: the basic shape of electric conduction of carbon fiber layer is a ring-type, and its manufacturing is extruding and moulding basically, and its shortcoming is to be difficult to uniformity at the thickness that makes progress in week, and its machine shaping manufacturing process is also comparatively complicated in addition.
Summary of the invention
The purpose of the utility model provides that a kind of cost is lower, the electric heating liquid-transport pipe-line of safety durable.
The technological scheme that realizes the utility model purpose is: a kind of electric heating liquid-transport pipe-line comprises the metal tube that is provided with the transfusion vestibule; It is characterized in that: be arranged with the carbon fiber electric heating cable on the metal tube outer wall, the electric heating cable is wrapped with the asbestos fiber thermal-protective coating.
In the such scheme, the equally spaced coiled screw thread of said electric heating cable wire.
In the such scheme, said carbon fiber electrothermal line cable wrap is drawn together two power lines, is wrapped in power line outer heat-resisting inner insulating layer, carbon fiber electrothermal layer and is wrapped in the outer heat-resisting external insulation layer of carbon fiber electrothermal layer; It is characterized in that: said carbon fiber electrothermal layer is to be formed by the carbon fibre electrothermal wire of many windings on inner insulating layer; The head and the tail two ends of said each bar carbon fibre electrothermal wire are electrically connected with two power lines, and the equally spaced winding of intermediate portion filament that is positioned at the head and the tail two ends is on inner insulating layer.
In the such scheme, said each carbon fibre electrothermal wire successively winding on inner insulating layer.
In the such scheme, said external insulation layer also is arranged with the fluoroplastic protective layer outward.
In the such scheme, said asbestos fiber thermal-protective coating is to adopt asbestos fiber to weave formed reticulated work.
In the such scheme, said thermal-protective coating also is enclosed with the fluoroplastic protective layer outward.
The utlity model has positive effect: (1) the utility model is through winding carbon fiber electric heating cable on the metal tube outer wall; And in the mode of electric heating cable outerwrap asbestos fiber thermal-protective coating; Make full use of the safety durable of asbestos and comparatively cheap price; Effectively reduce whole manufacture cost, and promote the reliability of long-term work.
(2) the utility model also through the mode at asbestos fiber thermal-protective coating outerwrap fluoroplastic protective layer, seals asbestos fiber, prevents that effectively asbestos fiber from working the mischief to surrounding enviroment.
