Abstract
The utility model provides a but hot oil line of heating device self -checking, including steel pipe and the electric heat tracing pipe of parallel mount outside the steel pipe who is used for carrying fluid medium steel pipe and electric heat tracing pipe wrap up outward in proper order has heat preservation and inoxidizing coating install leader cable and vice cable in the electricity heat tracing pipe. The utility model has the beneficial effect of simple structure, not only can the water back can also the automated inspection fault point, practice thrift cost of maintenance, improve operating efficiency.
Description
Technical field
This utility model belongs to utilidor technical field, and especially relating to a kind of heater can the utilidor of self-inspection.
Background technology
The essential structure of existing utilidor is that a single-phase cable passes a carbon steel pipe, and this cable leads to High Level AC Voltage,
Carbon steel pipe is fixed in thick medium tube by clamp.Logical upper alternating current in single-phase cable, carbon steel pipe is under electromagnetic action
Heating, thus heat to medium tube.Carbon steel pipe and medium tube have welding lead to connect simultaneously, thus reach common ground
Purpose.Heating and thermal insulation principle: also have heat-insulation layer outside total, wraps carbon steel pipe and medium tube simultaneously, thus
Realize the effect of pipe insulation.
Due to this kind of pipeline be often applied to buried, even include under water, three sections of wearing such as river, railway.So once carbon
Cable failure in steel pipe, water enters cable thus blows out, and there are currently no any way can position and detect.
Therefore in the case of original design, once heater breaks down, or excavation the most completely, trouble-shooting point,
Expend great amount of cost；Just can only weather hotter time use, lose the ability of all weather operations of pipe design.
Utility model content
The purpose of this utility model is to overcome prior art not enough, it is provided that a kind of heater can the utilidor of self-inspection,
Simple in construction, be not only able to add hot channel can also automatic fault detection point, save maintenance cost, improve operational efficiency.
The technical solution of the utility model is: a kind of heater can the utilidor of self-inspection, be situated between including for conveyance fluid
The steel pipe of matter and be installed in parallel in the electric tracing tube outside steel pipe, is enclosed with insulation outside described steel pipe and electric tracing tube successively
Layer and overcoat, be provided with leader cable and secondary cable in described electric tracing tube.
Further, described leader cable one end is provided with action of low-voltage pulse generator.
Further, described electric tracing tube is welded on outer surface of steel tube.
Further, the material of described heat-insulation layer is polyurethane foam, and heat-insulation layer is coated on outside steel pipe and electric tracing tube.
Further, the material of described overcoat is high density polyethylene (HDPE)；Overcoat is coated on outside heat-insulation layer.
This utility model has the advantage that with good effect: owing to using technique scheme, it is intended to design can self-inspection
Heater, can tracing trouble point automatically, and position.So can fault point position, specific aim rapidly
Formulation maintenance program, reduce cost, improve operational efficiency.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is elaborated.
Shown in structural representation as of the present utility model in Fig. 1-Fig. 2, this utility model provides a kind of heater can self-inspection
Utilidor, including for the steel pipe 1 of conveyance fluid medium be installed in parallel in the electric tracing tube 2 outside steel pipe 1, in institute
State and be enclosed with heat-insulation layer 3 and overcoat 4 successively outside steel pipe 1 and electric tracing tube 2, in described electric tracing tube 2, master is installed
Cable 5 and secondary cable 6.Described leader cable 5 one end is provided with action of low-voltage pulse generator 7.
Described electric tracing tube 2 is welded on steel pipe 1 outer surface.The material of described heat-insulation layer 3 is polyurethane foam, insulation
Layer 3 is coated on outside steel pipe 1 and electric tracing tube 2.The material of described overcoat 4 is high density polyethylene (HDPE)；Overcoat 4 wraps
It is overlying on outside heat-insulation layer 3.
The work process of this example: the heater that this utility model provides can the utilidor of self-inspection so that it is possess heating
Plant failure, the function of quick diagnosis location；For reaching above-mentioned purpose, include the most successively: for pumped (conveying) medium
Steel pipe, electric tracing tube, heat-insulation layer and overcoat；Described electric tracing tube is leader cable 5 and secondary 6 two electricity of cable
Cable；Leader cable 5 the most in addition alternating voltage, thus generate heat, secondary cable 6, as cable in stock, simultaneously as detection therefore
The reflected signal cable of barrier, if unidirectional cable, still cannot be carried out detection；At duct end, usually plant area, place
Action of low-voltage pulse generator 7, is connected on leader cable 5；If leader cable 5 cannot normally work, it is possible to the faults such as short interruption；
Now, start action of low-voltage pulse generator 7, carry out self-inspection and then may determine that position of failure point simultaneously, stop production to overhaul it
Before, it is also possible to use secondary cable 6 to continue heating.32km, self-inspection essence be can reach for this design effective length of buried pipeline
Really scope is positive and negative 10m.
Above an embodiment of the present utility model has been described in detail, but described content be only of the present utility model relatively
Good embodiment, it is impossible to be considered for limiting practical range of the present utility model.All made according to this utility model application range
Impartial change and improvement etc., within all should still belonging to patent covering scope of the present utility model.
