Abstract
The utility model discloses an armored temperature measuring and heating cable which comprises insulating materials and a metal protecting tube. Heating wires and thermocouple wires are arranged in the metal protecting tube; one end of each heating wire is welded together, and the other end thereof extends out of the metal protecting tube and is connected with a power source or a temperature controlling device; one end of each thermocouple wire is welded into a whole, and the other end thereof extends out of the metal protecting tube and is connected with a secondary instrument; and the insulating materials are filled among the heating wires, the thermocouple wires and the metal protecting tube and are magnesium oxide. The utility model has the advantages of long service life, high mechanical strength, radiation resistance, energy conversation, incombustibility and explosion protection.
Description
Technical field:
The utility model relates generally to a kind of cable, is specifically related to a kind of armouring thermometric heating cable that includes heating wire and thermocouple wire.
Background technology:
At present,, in heating, can't use thermocouple temperature measurement at special occasions such as hot flow paths, so a kind of novel cable that in heating, can carry out thermometric again of demand.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of armouring thermometric heating cable to be provided, and it will heat and measuring and controlling temp is concentrated in same the armouring, and will be easy to use, and reduce cost.
The utility model is achieved through the following technical solutions:
Armouring thermometric heating cable; include protection metal pipe, heating wire, the insulating material of end sealing; the terminals of heating wire are drawn from the end of protection metal pipe; it is characterized in that: the thermocouple wire that also has two radicles to be welded to connect in the described protection metal pipe; thermocouple wire is embedded in the described insulating material and mutually insulated, and the terminals of described two thermocouple wires are drawn from protection metal pipe.
Described armouring thermometric heating cable is characterized in that described insulating material is a magnesia powder.
Described armouring thermometric heating cable is characterized in that described heating wire is the column heating wire.
What the utility model adopted is four-wire system, and two column heating wire are wherein arranged, and heating wire is the soft attitude silk of non-oxidation, no spot; Insulating material is the pearl body that is processed into suitable size and length with magnesia powder earlier, carries out thermal sintering then in sintering furnace, and temperature is unsuitable too high, otherwise just make magnesia ceramicsization, but temperature also should not be low excessively, otherwise be difficult to form pearl, its endoporus adopts cylindrical four holes, plays the support positioning action.The column alloy silk of two unlike materials with its melting welding link (being the thermometric end), is put into the temperature field.Two different alloy materials will produce small generating positive and negative voltage this moment, the voltage difference that produces in the warm place of different temperatures, and logical secondary meter carries out signal and amplifies, linearization process, compensation shows a temperature temperature, reaches the purpose of thermometric.
The utility model is mainly used in requiring to heat but the place that can't use thermocouple temperature measurement, as hot flow path, and special occasions.Length of the present utility model is changeable; External diameter can be coarse to fine; Bending radius is 5 times of its diameter, can turn to different shape, is convenient to install; Have the characteristic of low capacitive reactance, low induction reactance, thereby have higher electrical power, can save electric energy 30%.Being equipped with suitable temperature-controlling system, temperature-controlled precision can reach ± and 5 ℃; Long service life and since the utility model be one can disturb, withstand voltage solid integral body, under normal underload situation, can use a lot of years; The utility model is to be that sheath, inorganic matter are the solid integral body of insulating barrier through compaction die with the metal tube, makes himself to have possessed high mechanical strength and robustness, causes external diameter distortion to reach 30% even be subjected to impact, the extruding of external force, but operate as normal still; Structure of the present utility model and structural material have determined its incombustibility energy, even also can not sustain damage or produce any pernicious gas under the situation of fire; Continuous seamless metal armour cover has determined cable to have water proofing property and high impermeable performance, even in liquid, in the vacuum, but the pressure place lays also operate as normal; Insulating barrier of the present utility model is an inorganic material, can not change the performance of material behind irradiation.It is the armour cover with the metal that the utility model is one, and inorganic matter is the solid integral body of insulating barrier through compaction die, can stand huge impact power, has explosion-proof characteristic.
Description of drawings:
Fig. 1 is a cross section structure schematic diagram of the present utility model.
Embodiment:
Armouring thermometric heating cable includes insulating material 3 and protection metal pipe 4, and heating wire 1 and thermocouple wire 2 are arranged in the described protection metal pipe 4, and heating wire 1 one end melting welding are one, and the other end stretches out outside the protection metal pipe 4 and is connected with power supply or temperature controlling instruments; Thermocouple wire 2 is the different alloy silk of material, and the melting welding of one end is one, and the other end stretches out outside the protection metal pipe 4 and is connected with secondary meter; Described heating wire 1, thermocouple wire 2 and 4 of protection metal pipes are filled with insulating material 3, and insulating material 3 is a magnesium oxide.The alloy silk of heating wire and unlike material is penetrated in the magnesium oxide that sinters, penetrate again in the protection metal pipe, make heating wire 1 and thermocouple wire 2 be parallel to protection metal pipe,, reach the required specification length of user, satisfy user's requirement by the drawing repeatedly of annealing.
