Abstract
The utility model relates to a precise controlled heating cable with a flat thermocouple. The utility model is characterized in that heating conductor and a temperature measuring feedback conductor of the thermocouple are arranged in an outer protecting sleeve, the length of the temperature measuring feedback conductor is the same with the that of the heating body, the temperature measuring feedback conductor is apart from the heating conductor in a cross mode and is parallel to the heating conductor, the shape of the outer protecting sleeve is in a flat structure and one surface of the outer protecting sleeve is provided with grooves which are uniformly distributed. The heating cable can synchronously realize heating and temperature measurement so as to conveniently control and adjust a temperature, enhance the heating conduction performance of the cable and enhance heating efficiency.
Description
Technical field
The utility model relates to a kind of heating cable, especially flat thermocouple accurate temperature controlling heating 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 cable does not have the function of control temperature; Existing heating cable profile is circular, and little with the tube contacts area, heat-transfer effect is relatively poor.
Summary of the invention
In order to overcome the deficiency of existing heating cable, the utility model provides a kind of flat thermocouple accurate temperature controlling heating cable, and the internal structure and the profile of cable have been done improvement, improves the efficiency of heating surface, and the function of control temperature is arranged.
Flat galvanic couple accurate temperature controlling heating cable of the present utility model comprises the heater (1) and the oversheath (4) of outsourcing insulation (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 profile of oversheath (4) is the flat structure.
In order to make in the heating cable temperature even, prevent local nest heat, increase radiating rate, the one side of the oversheath of flat structure of the present utility model (4) is provided with equally distributed groove (6).
The beneficial effects of the utility model are: 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 that temperature is controlled and adjustment; Because the flat structure of groove (6) is worn in oversheath (4) profile employing one, the conductive performance of cable heating is strengthened, improved the efficiency of heating surface.
Description of drawings
Fig. 1 is the schematic diagram of cross section of the present utility model.
In Fig. 1,1. heater, 2. thermocouple temperature measurement feedback conductor, the 3. insulating barrier of thermometric feedback conductor, 4. oversheath, the 5. insulating barrier of heater, 6. groove.
Embodiment
Shown in Figure 1 is the structural representation of the present utility model that adopts the three-phase alternating current power supply, and its heater (1) is made raw material with constantan, and heating power is stable, but heated perimeter is bigger; Adopt K level thermocouple temperature sensitive and added heat conduction, guaranteed the accurate, sensitive of temperature sensing; After heater (1) and thermocouple temperature measurement feedback conductor (2) difference extruded insulation layer and sulfuration, squeeze silicon rubber outward and make flat oversheath (4) when the utility model is made, promptly become the utility model through sulfuration again.
Claims (2)
1, a kind of flat thermocouple accurate temperature controlling heating cable, the heater and the oversheath that comprise outsourcing insulation, 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 profile of oversheath is the flat structure.
2, by the described flat thermocouple of claim 1 accurate temperature controlling heating cable, it is characterized in that the one side of the oversheath of flat structure is provided with equally distributed groove.
