Abstract
The electric heating pipe is composed of wire holder, insulator, fastener, medium in heating pipe, resistance wire and metal pipe, and is characterized by that in the centre of electric heating pipe or one side of the electric heating pipe a temp. control device is set, and includes external sleeve, filling material, several temp. controllers and leads connected with temp. controllers and wire holder.
Description
The utility model relates to a kind of electric heating tube, and particularly a kind of electricity of energy A.T.C adds pipe.
Traditional electric heating tube is not provided with temperature control equipment, and the heating tube after the improvement is provided with a thermostat at heater housing, is used for measuring and control heating tube heating-up temperature, because thermostat is arranged on the heating tube shell, has influenced the precision of thermometric.The hot working heating tube is a tubular electrothermal element, according to " metal fever processing application manual " (China Machine Press's publication " metal fever processing application manual " is write group and write) record, tubular electrothermal element consists of compositions such as binding post, insulator, securing member, magnesia powder inserts, resistance wire, metal tube shell, selects difform tubular electrothermal element for use according to different containers; In recent years, people constantly study and adopt novel inserts and resistance wire to raise the efficiency, and control automatically but all fail realization heat temperature itself; The control temperature adopts thermocouple usually, (China Machine Press publishes according to " temperature instrumentation and high-frequency device ", the Xianyang machine is made school and is write), thermocouple is that the solderable conductor with two heterogeneities connects an end and forms, the two ends of weldering do not connect Displaying Meter, during thermometric, the company's of weldering end are contacted with tested thermal source, by Displaying Meter, can learn the temperature of tested thermal source.As need control temperature, temperature auto control must be realized by relevant switching circuit.Thereby can not realize heating, thermometric, be controlled to one, structure is bigger, measures to change manyly, and certainty of measurement is not high.
The purpose of this utility model provides a kind of collection heating, thermometric, is controlled to be one, and compact conformation, and the certainty of measurement height has the electric heater of multistage temperature control.
The utility model is achieved in that on electric heating tube side or center one group of temperature controller group of being made up of some temperature controllers is set that each temperature controlled specification is selected as required, is provided with filler between each temperature controller; Each temperature controller connects by lead-in wire and wiring base.
Because temperature controller is other or center at heating tube, thereby has improved the accuracy of thermometric, adopt the thermostat of several different sizes, can select the control temperature that is fit to user's needs flexibly for use, and need not numerous and diverse electronic circuit.The heating be controlled to one, simplified the structure of heater and controller widely, improved reliability of products.
Below in conjunction with the embodiment in the accompanying drawing the utility model is further described.
Accompanying drawing 1. is built-in electric heater schematic diagram.
Accompanying drawing 2. is side-connecting electric heater schematic diagrames.
3. be the left view of accompanying drawing 2.
1 is junction block in the accompanying drawing, the 2nd, and heating tube, the 3rd, lead-in wire, the 4th, filler, the 5th, thermostat, the 6th, metal tube, the 7th, resistance wire, the 8th, separate matter in the heating tube, 9 outer tubes.
Embodiment one, at spirality electric heater center one outer tube (9) is set, outer tube is divided into several layers in (9), is provided with thermostat (5) in every layer, every interlayer is separated by inserts (4), and the outlet of thermostat (5) is drawn by lead-in wire (3) and linked to each other with junction block (1).Electric heating tube (2) is by separating matter (8) in metal tube (6) and the heating tube and resistance wire (7) is formed, and resistance wire (7) communicates with junction block (1).
Embodiment two, in waveform electric heater one side one outer tube (9) is set, outer tube is divided into several layers in (9), is provided with thermostat (5) in every layer, every interlayer is separated by inserts (4), and the outlet of thermostat (5) is drawn by lead-in wire (3) and linked to each other with junction block (1).Electric heating tube (2) is by separating matter (8) in metal tube (6) and the heating tube and resistance wire (7) is formed, and resistance wire (7) communicates with junction block (1).
Inserts (4) can adopt epoxy resin etc., and thermostat (5) can be selected thermostat reliable and that specification limit is satisfied the demand for use
Claims (1)
- A kind of electric heating tube is made up of degree of Jie, resistance wire, metal tube etc. in junction block, insulator, securing member, the heating tube, it is characterized in that at the center of heating tube or a side is provided with by outer tube, inserts, some thermostats and forms with the lead-in wire that thermostat links to each other with junction block.
