Description
Technical field
The utility model is related to motor hot pipe technique field more particularly to a kind of band thermocouple single head stainless steel electrical heating
Pipe.
Background technology
The operation principle of electrothermal tube is that heating wire generates heat after being powered in metal tube, by the metal shell of electrothermal tube to
Heating target transmits heat.Heating wire can allow the temperature of heater itself rapidly to rise after being powered, and temperature is caused to be difficult to accurately control
System.
Therefore, the prior art is defective, needs to improve.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide one kind and occupy little space, and are ready for controlling
Temperature prevents the band thermocouple single head stainless steel electric heating tube that temperature rise is excessively high.
The technical solution of the utility model is as follows：A kind of band thermocouple single head stainless steel electric heating tube, including electric heating tube
Ontology, the electric heating tube ontology includes inner heat-conductive pipe, the outer steel pipe that is arranged on the outside of inner heat-conductive pipe and is arranged in interior heat conduction
Heating layer between pipe and outer steel pipe, the heating layer are spiral heating silk, and rabbeting in the inner heat-conductive pipe has electric heating to draw stick, institute
The one end for stating electric heating tube ontology is equipped with trepanning, and the electric heating draws stick and extends from the tapping, and the electric heating draws stretching for stick
Outlet is connected with conductor wire, is also built-in with K-type thermocouple in the inner heat-conductive pipe, and the K-type thermocouple is from electric heating tube ontology
The tapping of one end extends.
Further, the outer steel pipe uses high temperature stainless steel industry pipe.
Further, the spiral heating silk uses 2080 heating wire of high temperature.
Further, the inner heat-conductive pipe is high-purity seawater magnesia rod.
Further, the electric heating draws stick equipped with two, and material is nickel-base alloy.
Further, the conductor wire uses pure nickel line.
Further, the K-type thermocouple is equipped with positive and negative two.
Compared with the existing technology, the beneficial effects of the utility model are：The utility model is built-in with K-type thermocouple, by K
Type thermocouple is integrally formed with heater, and when use can save space, by K-type thermocouple, can prevent the temperature of heater itself
Degree rises too high, accurately controls temperature.

In the present embodiment, the outer steel pipe 12 uses high temperature stainless steel industry pipe, and there is fast erosion resistant high temperature resistant of conducting heat to obtain
Feature；The spiral heating silk uses 2080 heating wire of high temperature, makes fever evenly, longer life expectancy；The inner heat-conductive pipe is height
Purity seawater magnesia rod has the characteristics that 1300 DEG C of indeformable free from admixtures of high temperature resistant；The electric heating draws stick 4 and is equipped with two,
Material is nickel-base alloy；The conductor wire 5 uses pure nickel line.
The utility model is integrally formed by being built-in with K-type thermocouple, by K-type thermocouple with heater, and when use can be saved
Save space can prevent that the temperature rise of heater itself is excessively high, accurately controls temperature by K-type thermocouple.The utility model value
It must be used more widely.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all in this practicality
All any modification, equivalent and improvement etc., should be included in the guarantor of the utility model made by within novel spirit and principle
Within the scope of shield.
