Fig. 2 is the cross-sectional view of Fig. 1;
In figure, 1 be delivery line, 2 for pipe joint, 3 for heating tape, 4 for wire, 5 for terminal, 6 for thermal insulation layer, 7 for joint protective folder, 8 for protective layer, 9 be conductor protective layer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
Shown in figure 1 and Fig. 2, an embodiment of the present utility model is the Urea pipeline using band heating, comprising delivery line 1, the end of described delivery line 1 is provided with pipe joint 2, the outer wall of even more important above-mentioned delivery line 1 is provided with heating tape 3, and this heating tape 3 is connected with terminal 5 by wire 4, be more also provided with thermal insulation layer 6 in the outside of this heating tape 3.
Further, for avoiding above-mentioned pipe joint 2 to be damaged in use, joint protective folder 7 also also can be installed in the outside of pipe joint 2;
In the present embodiment, namely delivery line can be used as the pipeline of urea liquid circulation, also can be heated by heating tape when temperature is too low, and realize temp auto-controlled adjustment by sensor, under the effect of thermal insulation layer, ensure that the temperature of delivery line inside is in constant state all the time, avoid urea liquid generation crystallization, ensure the normal use of diesel oil transmitter.
For promoting heating pipe line to the heating property of urea liquid; solution is avoided to be cooled at two ends after tube body is heated; in the embodiment that the utility model is more preferably for technical solution problem; preferably on above-mentioned joint protective folder 7, set up heating tape 3; and heating tape 3 is also connected with terminal 5 by wire 4, heating tape 3 is preferably by being fixed on by the mode of epoxy glue embedding on joint protective folder 7
According to above-mentioned thinking, also can establish heating tape 3 in the inside of pipe joint 2, and be connected with terminal 5 by wire 4 heating tape 3, it is inner that heating tape 3 adopts the mode of secondary low-voltage injection moulding to be directly fixed on pipe joint 2.
On the other hand, inventor also considers that the routine of heating tape 3 on delivery line 1 body is arranged, in concrete test, heating tape 3 is set to two, for being arranged on the axial both sides of delivery line 1 respectively, and with the outer wall close contact of delivery line 1.
Simultaneously for ensure heating pipe line in use thermal insulation layer be not destroyed, preferably again at the outside of thermal insulation layer 6 suit protective layer 8, and this protective layer 8 and joint protective are pressed from both sides 7 and encapsulate and be connected.According to aforesaid thinking, also can also be set with conductor protective layer 9 in wire 4 outside between heating tape 3 and terminal 5.And aforesaid protective layer 8 is plastic flexible pipe with conductor protective layer 9.
In particular; the pipe joint 2 at above-mentioned delivery line 1 two ends preferably adopts quick inserting joint; the joint of quick inserting joint and protective layer 8 and joint protective press from both sides 7 and encapsulate with the material of insulative water-proof; an end also packed segment length of protective layer 8; if joint protective folder 7 has wire to draw, then a conductor protective layer 9 also packed segment length.
Above-mentioned delivery line 1 body can for meeting the flexible pipe of any materials that delivered solution requires, such as can adopt outer is PA12, and internal layer is the composite urea solution delivery hose of ETFE.Heating material in heating tape 3 can for having the heating bandlet of heat generation characteristic after energising.Such as, adopt inner core to be electric heating wire outer skin material to be the heating plastic of PTC in the present embodiment, the line with heating function adopted in this way is high temperature resistant, does not give a discount, intensity is large.The specific resistance specification of ribbon heater can be mated according to the length of delivery line 1 body, makes the power of electric heating urea tube control in scope of design, prevents the solution Yin Wendu of delivery line and internal flow too high and the change of Performance and quality occurs.And more particularly; above-mentioned protective layer 8 can adopt corrugated plastic flexible pipe; conductor protective layer 9 also can adopt corrugated plastic flexible pipe, selects the benefit of bellows to be not only embodied in bending not easily discounting, and has also embodied its advantage when ripple joint area hereinafter encapsulates.
