Description
Technical field
The utility model is related to electric tracing field, specially a kind of electric tracing tube cable structure.
Background technology
Electric-heating belt is made of conducting polymer and two parallel metal wires and insulating sheath etc..Its main feature is that conductive
Polymer has very high ptc characteristics, and is mutually in parallel, and can be automatically adjusted with the temperature change of heated object system defeated
Go out power, the temperature of volitional check heating, can arbitrarily truncate or spreading uses in a certain range, and allow to cross over many times weight
It is folded and without high temperature hotspot and the worry burnt, electric tracing umbilical is electric-heating belt to be packed into outer tube and filling heat insulating wall is formed
, all it is fluting or trepanning on outer tube for monitoring temperature at present, is sealed again after being then put into temperature element, in this way meeting
Electric tracing tube ontology can be caused centainly to damage, there are certain security implications during use.
Invention content
To solve the above-mentioned problems, the utility model provides a kind of electric tracing tube cable structure, can realize that temperature is supervised
Outer tube is not caused to damage while survey, it is ensured that reliable using process safety.
Its technical solution is such：A kind of electric tracing tube cable structure comprising outer tube is provided in the outer tube
Heating tape is filled with insulating layer between the heating tape and the outer tube, which is characterized in that it further includes temperature probe and adopts
Sample PFA pipes, the temperature probe are close to the sampling PFA pipes, and the temperature probe connects probe wire, the probe wire end
Portion exposes to described outer tube one end.
It is further characterized by the heating tape is Self-controlled electric-heating belt or invariable power electric-heating belt；
The temperature probe includes two, model PT100 probes；
Outer tube is provided at both ends with thermal-shrinkage finger sleeve, and the junction of the thermal-shrinkage finger sleeve and the outer tube is set with heat-shrink tube
Set；
The heating tape and sampling PFA pipe surfaces are enclosed with heat reflection aluminium foil；
The insulating layer is moisture-proof glass fibre twining package tape；
The outer tube is PVC sheath.
After the structure of the utility model, temperature probe is processed in outer tube simultaneously with heating tape, will not be to housing
Pipe causes to damage, and connecting external temperature measuring equipment by probe wire realizes monitoring temperature, realizes reliable and secure temperature monitoring.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model side view enlarged diagram.
Specific implementation mode
See Fig. 1, shown in Fig. 2, a kind of electric tracing tube cable structure comprising outer tube 1 is provided with heating tape in outer tube 1
2, temperature probe 3 and sampling PFA pipes 7 are filled with insulating layer between heating tape 2, temperature probe 3, sampling PFA pipes 7 and outer tube 1
4, temperature probe 3 is close to sample PFA pipes 7, and temperature probe 3 connects probe wire 5, and 5 end of probe wire exposes to outer tube 1 one
It holds and is used to connect external temperature measuring equipment.Heating tape 2 is Self-controlled electric-heating belt or invariable power electric-heating belt；Temperature probe 3 wraps
Two are included, model PT100 probes can facilitate accurate monitoring temperature.Outer tube 1 is provided at both ends with thermal-shrinkage finger sleeve 8, pyrocondensation
Fingerstall 8 and the junction of outer tube 1 are set with shrinkable sleeve 9；Heating tape and sampling PFA pipe surfaces are enclosed with aluminium foil 10, play
Thermal reflection；Insulating layer 4 is moisture-proof glass fibre twining package tape；Outer tube 1 is PVC sheath, and temperature resistant range is -40-90 DEG C.Figure
In 6 be heating tape core wire.
