Abstract
An automatic temperature-controlled heat tracing cable comprises a sheath below which a shielding layer and a heating lead wire are arranged in sequence, wherein an automatic temperature controlling layer is arranged below the insulating layer, the heating lead wire is embedded in the automatic temperature controlling layer, and the automatic temperature controlling layer can adopt common PTC. The automatic temperature-controlled heat tracing cable is provided with the automatic temperature controlling layer, thereby not only having simple structure and lower cost but also being capable of automatically controlling the temperature of the heat tracing cable.
Description
Technical field
The utility model relates to a kind of heating cable, relate in particular to a kind of can A.T.C from the temperature control accompanying-heat cable.
Background technology
Accompanying-heat cable is since coming out, though its history only has the more than ten years, many fields but it has been widely used at present, as mainly utilizing at oil in industrial aspect, chemical industry, cogeneration power plants etc. need prevent that a pipeline or jar interior liquid substance from solidifying/the slow place of flowing velocity, are mainly used in companion's heat of fire protection pipeline aspect communal facility, can be used for heating of house and the antifreeze aspect of yard piping in winter aspect civilian.
But in the prior art, often there is the bad control of heat traced pipeline temperature in most accompanying-heat cable, causes local temperature overheated, will certainly certain infringement be arranged to accompanying-heat cable and pipeline itself like this, also makes whole tracing system have certain potential safety hazard.
Be directed to above-mentioned situation, be necessary to provide a kind of in fact from the temperature control accompanying-heat cable, should be not only simple in structure from the temperature control accompanying-heat cable, cost is lower, and can control the temperature of accompanying-heat cable automatically, to overcome the defective of accompanying-heat cable in the prior art.
The utility model content
The purpose of this utility model just provides a kind of from the temperature control accompanying-heat cable, should be not only simple in structure from the temperature control accompanying-heat cable, and cost is lower, and can control the temperature of accompanying-heat cable automatically.
For reaching above-mentioned purpose, it is a kind of from the temperature control accompanying-heat cable that the utility model provides, should comprise sheath from the temperature control accompanying-heat cable, be disposed with screen under the described sheath, insulating barrier and heating-wire, wherein, the below of described insulating barrier also is provided with from the temperature control layer, and described heating-wire is embedded within the temperature control layer.
Especially, described is flat structure from the temperature control layer, and described heating-wire is a cylindrical structure.
Especially, describedly can be common PTC from the temperature control layer, any of fire-retardant PTC and fluorine-containing PTC.
Compared to prior art, it is a kind of from the temperature control accompanying-heat cable that the utility model provides, should be not only simple in structure from the temperature control accompanying-heat cable, and cost is lower, and can control the temperature of accompanying-heat cable automatically.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure:
1, sheath; 2, screen; 3, insulating barrier; 4, from the temperature control layer; 5, heating-wire.
Embodiment
Please refer to shown in Figure 1, Fig. 1 is the structural representation of the utility model embodiment, it is a kind of from the temperature control accompanying-heat cable that the utility model provides, should comprise sheath 1 from the temperature control accompanying-heat cable, in present embodiment, described sheath 1 is improvement property polyolefin, and described sheath is coated with screen 2 for 1 time, and described screen 2 forms for zinc-plated soft circular copper wire braiding, coverage density is 80%, described screen 2 is arranged with insulating barrier 3, and in present embodiment, described insulating barrier 3 is a fire retardant polyolefin, and described insulating barrier 3 is arranged with from temperature control layer 4, described is common PTC from temperature control layer 4, and any of fire-retardant PTC and fluorine-containing PTC is so that can control the temperature of accompanying-heat cable as required automatically, in present embodiment, described is common PTC from temperature control layer 4, and described be flat structure from temperature control layer 4, in addition, describedly in temperature control layer 4, also be embedded with two heating-wires that are arranged in parallel 5, in present embodiment, described heating-wire 5 is a copper conductor, and it is a cylindrical structure.
It is a kind of from the temperature control accompanying-heat cable that the utility model provides, and should be provided with from temperature control layer 4 from the temperature control accompanying-heat cable, and not only simple in structure, cost is lower, and can control the temperature of accompanying-heat cable automatically.
Fig. 1 is the structural representation of the utility model embodiment; but a kind of arrangement mode and this a kind of shape that is not limited to this a kind of assembly from the temperature control accompanying-heat cable of the utility model; as shown in Figure 1; satisfying on the basis of its function; can be along with from the change of the shape of temperature control layer and change; the change that anyone makes arrangements of components mode of the present utility model, model and shape on principle of the present utility model basis has easily then all fallen into protection range of the present utility model.
