The inner ring heating wire does not contact the outer ring heating wire in the tube. Both end heads of the inner ring heating wire and the outer ring heating wire are separately connected with lead wire devices (cold needles) on both ends of the metallic outer tube 4. The utility model has the advantages of novel and reasonable design, convenient installation, high efficiency, high quality, and low price. The utility model is an advanced fitting of various electrical heating products and devices. Different powers can be obtained when the same electric heating tube is used to achieve different functions, such as heating, heat insulation, rapid heating, etc.
Description
The utility model relates to a kind of electrothermal tube, particularly compound many power electrothermal tube.
Electrothermal tube of the prior art, has only single heating wire in its pipe, also be that heating power is single fixing, when device need to change power and when making it the function of insulation, fast heat, slow heat, rely on transformer to come buck or add several electrothermal tubes, this sampling device just needs bigger space of components, and installation is complicated, cost is increased.
The purpose of this utility model is intended to overcome the deficiencies in the prior art and a kind of compound many power electrothermal tube that Unit Installation is easy, can obtain the low high effect of multiple power, cost with an electrothermal tube that makes is provided.
The purpose of this utility model is achieved in that
A kind of compound many power electrothermal tube, comprise metal outer pipe 4, inside stuffing 7, it is characterized in that the empty road, centre that is even spiral helicine outer ring heating wire 5 in metal outer pipe 4 inside is even spiral helicine inner ring heating wire 6 by coaxial packing into, inside and outside circle heating wire does not contact in pipe, and its two ends is connected with the lead wire device (cold pin) at metal outer pipe 4 two ends respectively.
---described lead wire device (cold pin) comprises the cold pin of cold pin in top and bottom, and the cold pin in top comprises top stem 8, insulating case 9, electrode metal pipe 10 and upper insulator 11; The cold pin in bottom comprises bottom insulating part 1, bottom stem 2 and outer ring nut 3.
---described lead wire device (cold pin) is cold pin other ends in top when being the cold pin in bottom at an end of metal outer pipe 4, and an end of inner ring heating wire 5 links to each other with the top stem 8 of the cold pin in top, and the other end links to each other with the bottom stem 2 of the cold pin in bottom; One end of outer ring heating wire 6 links to each other with the electrode metal pipe 10 of the cold pin in top, and the other end links to each other with the outer ring nut 3 of the cold pin in bottom.
---described lead wire device (cold pin) is when being both the cold pin in bottom at the two ends of metal outer pipe 4, and the two ends of inner ring heating wire 5 link to each other with two bottom stems 2 of the cold pin in bottom respectively; The two ends of outer ring heating wire 6 link to each other with two outer ring nuts 3 of the cold pin in bottom respectively.
---described lead wire device (cold pin) is when being both the cold pin in top at the two ends of metal tube 4, and the two ends of inner ring heating wire 5 link to each other with two top stems 8 of the cold pin in top respectively; The two ends of outer ring heating wire 6 link to each other with two electrode metal pipes 10 of the cold pin in top respectively.The utility model is described in further detail below by drawings and Examples:
Fig. 1 is that the utility model one end is the structure cutaway view that the cold pin other end in top is the cold pin in bottom
Fig. 2 is the structure cutaway view that the utility model two ends are both the cold pin in bottom
Fig. 3 is the structure cutaway view that the utility model two ends are both the cold pin in top
Fig. 4 is the cold needle construction cutaway view in the top of utility model
Fig. 5 is the cold needle construction cutaway view in the new bottom of this practicality
In Fig. 1 to Fig. 5,1 is that bottom insulating part, 2 is that bottom stem, 3 is that outer ring nut, 4 is that metal outer pipe, 5 is that outer ring heating wire, 6 is that inner ring heating wire, 7 is that filler, 8 is that top stem, 9 is that insulating case, 10 is that electrode metal pipe, 11 is a upper insulator
Operation principle of the present utility model is: establish the resistance that R1 is an outer ring heating wire 6, R2 is the resistance of inner ring heating wire 5, is applying under the situation of rated voltage, and the power when using R1 (heating state) separately is P1=V
2/ R1; Power when using R2 (insulation situation) separately is P2=V
2/ R2; Power P 3=V when R1, R2 connect
2/ (R1+R2), and when R1, R2 are in parallel, power P 4=V then
2/ R1 ∥ R2, at this moment
So be connected with different connected modes when the cold pin in top encloses heating wires with the cold pin in bottom and two, the regulation and control of adding external control circuit just can obtain several different power with an electrothermal tube.
During enforcement, select the even helicoid of the heating wire of different-diameter and resistance with spiral filament forming machine coiled certain-length, in on special device, inciting somebody to action, outer ring heating wire coaxial positioning cover gets up, weld with the appointed part of cold pin respectively at its two, by the requirement of design model, metal pipe material is cut into certain-length, place on the lead-in wire dress powder machine, the Internal and external cycle heating wire that welds cold pin is drawn in the metal tube, load the filler such as the magnesium powder of insulating heat-conductive, seal after tamping, more linear heat-generating pipe is put in the shaper miscellaneous, the curved electrothermal tube that is pressed into required form, promptly become the utility model, in order to make various electric heaters, flatiron, the product facility of band such as coffee pot heating and heat preserving function.
The utility model is novel in design, and rationally same electrothermal tube can obtain different power to reach difference in functionalitys such as heating, insulation, Fast Heating, makes easy for installation efficiently, inexpensive, is the advanced accessory of various electric heating product facilities.
