Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
To enable above-mentioned purpose of the present utility model, feature and advantage more obvious understandable, below in conjunction with the accompanying drawings and tool
Body embodiment is described in further detail to the utility model.
As shown in Figure 1-2, the utility model provides a kind of low adsorption flexible heat tracing pipe 1, including four positioned at innermost layer
Fluoride tubes 8, the variable copper litz wire 7 of the internal diameter of the outside of tetrafluoroethene pipe 8 is wrapped in, is arranged on the outside of copper litz wire 7
Heater strip 6, the outside parcel reflected compliance metallic film 5 of heater strip 6, the outside of reflected compliance metallic film 5 is locked by heat-shrink tube 4
Tightly, the outside of heat-shrink tube 4 is coated with heat-insulation layer 3 and protective layer 2 successively.Protective layer 2 is nylon webmaster or stainless steel tube, reflected compliance
Metallic film 5 is aluminium foil, and the heat-insulation layer 3 is rubber insulating tube.The endoporus integrally through locker of tetrafluoroethene pipe 8, two
End uses locker external stability, can not only so ensure the fastness and air-tightness of tetrafluoroethene pipe 8, also avoid in pipe
Gas contacts with the locker of metal material, reduce interference, and thereby also reduce gas in pipe thermal loss (metal
Thermal conductivity is apparently higher than plastics such as tetrafluoroethene), while tetrafluoroethene pipe 8 itself is carried certain pulling force, and can
Hold on the adjunct of outside.
The variable tight of copper litz wire 7 of internal diameter uses netted volume in the outside of tetrafluoroethene pipe 8, copper litz wire 7
The mode of knitting, which weaves, to be formed.The outside of copper litz wire 7 sets some heater strips 6, then with aluminium foil by heater strip 6 and the He of copper litz wire 7
Tetrafluoroethene pipe 8 tightly wraps inside.Because aluminium foil and the outside of heater strip 6 and the outside of copper litz wire 7 are in close contact, will can heat
The heat transfer in the outside of silk 6 is to copper litz wire 7, and the inner side heat of heater strip 6 is by the copper litz wire 7 that directly contacts by heat
It is delivered on tetrafluoroethene pipe 8.The thermal conductivity of copper litz wire 7 is very high, and its netted weaving manner can be in axial direction and footpath
Heat is transmitted to both direction so that temperature is uniformly transmitted to the tetrafluoroethene pipe 8 of inner side.Aluminium foil is by part infrared reflection
Return so as to reduce thermal loss.Heat-shrink tube 4 is locked at outside aluminium foil, then the rubber insulating tube on the set of the outside of heat-shrink tube 4, rubber
It is then to provide protection by nylon webmaster or stainless steel tube outside insulating tube.Copper litz wire 7 electrically connects with heater strip 6, directly as
Wire uses.The front end of heat tracing pipe 1 of the application is connected with a filter, and rear end is connected with a quick connector, during connection, tetrafluoro second
Alkene pipe 8 is fixed by the way of external locking through the through hole among quick connector, can effectively avoid the gas and gold in pipe
Belong to component contact.The fast plug connecting mouth of quick connector and main frame connects.Heat tracing pipe 1 of the present utility model also includes temperature sensor,
The temperature sensor does not contact between aluminium foil and copper litz wire 7 with the heater strip 6, can conveniently detect heat tracing
The heating-up temperature of pipe 1.Heat tracing pipe 1 of the present utility model is small to gas absorption effect, and transfer conduit uses polytetrafluoroethylene (PTFE) material
Material, centre do not contact any metal parts, effectively avoid the globule from separating out.
Part infrared reflection is returned to reduce thermal loss by the aluminium foil in the outside of heater strip 6, so as to reduce outside heat tracing pipe 1
The temperature of layer, prevent that the heater strip 6 reduced on heat tracing pipe 1 heated to the outer layer rubber insulating tube longevity rubber insulating tube by thermmohardening
The influence of life；By coating nylon webmaster or stainless steel tube on the outside of rubber insulating tube, can not only heat-insulation layer be prevented to be destroyed,
Heat-insulation layer hardening affected by environment can also effectively be prevented.
Apply specific case in the utility model to be set forth principle of the present utility model and embodiment, the above
The explanation of embodiment is only intended to help and understands method and its core concept of the present utility model；Meanwhile for the one of this area
