Abstract
The outer sheath of the invention has a heating conductor and a feedback wire of temperature thermocouple which is crossed with the heating conductor and has identical length. The cross section of the outer sheath shapes zigzag form. The invention can easy the temperature control and adjustment, and enhance the heat conductibility.
Description
Technical field
The present invention relates to a kind of heating cable, especially sawed precisive synchronized temperature-adjusting heating electric cable.
Background technology
Heating cable is mainly used in the heating to oil pipeline, liquid chemical product conveyance conduit etc. in cold district winter, influences the problem of normal conveying because of cold junction to solve oil and liquid chemical product in carrying.Existing heating cable mainly adopts the resistance wire heating, and the efficiency of heating surface is relatively poor, and electric energy loss is bigger, and the temperature control precision of cable is relatively poor; The profile of existing heating cable be a circle, during use and the tube contacts area little, heat-transfer effect is relatively poor.
Summary of the invention
In order to overcome the deficiency of existing heating cable, the invention provides a kind of sawed precisive synchronized temperature-adjusting heating electric cable, the internal structure and the profile of cable have been done improvement, improve the efficiency of heating surface, and the heating-up temperature of the accurate control cable of energy.
Sawed precisive synchronized temperature-adjusting heating electric cable provided by the invention comprises the heater (1) of outsourcing insulation (5) and the oversheath (4) that coats outside insulating barrier (5), in oversheath (4), be provided with intersect with heater (1) be separated by, with the thermocouple temperature measurement feedback conductor (2) of the parallel outsourcing insulation of length (3), the cross section of oversheath (4) be shaped as the zigzag form that simultaneously is provided with groove (6).
The invention has the beneficial effects as follows: since heater (1) intersects with thermocouple temperature measurement feedback conductor (2) be separated by, parallel with length, heating is synchronous with thermometric, is convenient to temperature control and adjustment, the raising temperature-controlled precision; Because oversheath (4) profile adopts one side to be provided with the zigzag form of groove (6), one side flat during use is close to pipeline, and contact area is big, and the conductive performance of cable heating is strengthened, and has improved the efficiency of heating surface; The structure that one side is provided with groove (6) makes the interior temperature of heating cable even, prevents local nest heat, accelerates the heat radiation of local hot spot.
Description of drawings
Fig. 1 is the schematic diagram of cross section of the present invention.
In Fig. 1,1. heater, 2. thermocouple temperature measurement feedback conductor, the 3. insulating barrier of thermocouple temperature measurement feedback conductor, 4. oversheath, the 5. insulating barrier of heater, 6. groove.
Embodiment
Power supply of the present invention is a three-phase alternating current, and Fig. 1 is a cross-sectional structure schematic diagram of the present invention, and its heater (1) is made as raw material with constantan, and heating power is stable, but heated perimeter is bigger; Adopt K level thermocouple temperature sensitive to add heat conduction, guarantee the accurate, sensitive of temperature sensing; After outside heater (1) and thermocouple temperature measurement feedback conductor (2), extruding silicone rubber insulation layer (5) and (3) and sulfuration when the present invention makes respectively, the outer silicon rubber that squeezes is made the saw shape oversheath (4) that one side is provided with groove (6), promptly makes the present invention through sulfuration again.
Claims (1)
1, a kind of sawed precisive synchronized temperature-adjusting heating electric cable, comprise the heater of outsourcing insulation and the oversheath that outside insulating barrier, coats, it is characterized in that in oversheath being provided with intersect with heater be separated by, with the thermocouple temperature measurement feedback conductor of the parallel outsourcing insulation of length, the cross section of oversheath be shaped as the zigzag form that simultaneously is provided with groove.
