Abstract
The utility model relates to a double-power electric heating tube, which mainly comprises a stainless steel tube and magnesia powder arranged inside the cavity of the stainless steel tube. A short lead-out bar, a first resistance wire, a pull wire, a third resistance wire and a short lead-out bar are sequentially connected inside the stainless steel tube to form a loop, and a long lead-out bar, a second resistance wire and a long lead-out bar are sequentially connected inside the stainless steel tube to form another loop. The first resistance wire is installed at the bottom of the stainless steel tube, and the second resistance wire is installed at the top of the stainless steel tube. The stainless steel tube is fixedly connected with a mounting flange. On the occasion of ever-increasing raw material cost of electric heating tube, the novel single-tube double-power electric heating tube remarkably reduces cost.
Description
Technical field
The utility model relates generally to the electric heating tube field, mainly is a kind of pair of power electric heating tube.
Background technology
Traditional flange form two power electric heating tubes be to use two independently heating tube realize, under the growing situation of the electric heating tube cost of raw material, two independently heating-pipe structure increased cost greatly.
Summary of the invention
The utility model will solve in the above-mentioned prior art not enough, and a kind of pair of power electric heating tube is provided.
The utility model solves the technical scheme that its technical problem adopts: this pair of power electric heating tube, mainly comprise stainless steel tube, in the tube chamber of stainless steel tube magnesia powder is arranged, be provided with in the described stainless steel tube by a short eduction rod, first resistance wire, wire drawing, the 3rd resistance wire and the loop that short eduction rod connects and composes successively, also be provided with by a long eduction rod, second resistance wire and another loop that long eduction rod connects and composes successively.
Described first resistance wire is installed in the bottom of stainless steel tube, and second resistance wire is installed in the top of stainless steel tube.
Described stainless steel tube is fixedlyed connected with mounting flange.
The effect that the utility model is useful is: under the growing situation of the electric heating tube cost of raw material, the two power electric heating tube structures of this novel single tube have reduced cost greatly.
Description of drawings
Fig. 1 is main TV structure figure of the present utility model;
Fig. 2 is the expansion johning knot composition of the short eduction rod of the present utility model and first resistance wire;
Fig. 3 is the expansion johning knot composition of the long eduction rod of the present utility model and second resistance wire;
Description of reference numerals: 1-mounting flange, 2-short eduction rod, 3-long eduction rod, 4-stainless steel tube, 5-magnesia powder, 6-the first resistance wire, 7-the second resistance wire, 8-wire drawing, 9-the three resistance wire.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in the figure, this pair of power electric heating tube mainly comprises stainless steel tube 4, and magnesia powder 5 is arranged in the tube chamber of stainless steel tube 4, and stainless steel tube 4 is fixedlyed connected with mounting flange 1.Be provided with in the described stainless steel tube 4 by a short eduction rod 2, first resistance wire 6, wire drawing 8, the 3rd resistance wire 9 and the loop that short eduction rod 2 connects and composes successively, also be provided with by long eduction rod 3, second resistance wire 7 and another loop that long eduction rod 3 connects and composes successively.Described first resistance wire 6 is installed in the bottom of stainless steel tube 4, and second resistance wire 7 is installed in the top of stainless steel tube 4.
Eduction rod launches the short-and-medium eduction rod 2 of schematic diagram: Fig. 2 with resistance wire and is connected the middle part wire drawing with first resistance wire 6,9 spot welding of the 3rd resistance wire; 7 spot welding are connected long eduction rod 3 with second resistance wire among Fig. 3.
This electric heating tube design feature: the heating tube among Fig. 1 belongs to flange form single tube electric heating tube, uses unique single tube mariages technology to reach the requirement of the two power of single heating tube.And the resistance wire by Fig. 2, Fig. 3 and draw excellent interconnection technique, make wherein a power concentration at wire drawing position, heating tube bottom consumed power not substantially, another power concentration is drawn rod in heating tube top length makes resistance wire concentrate on the spiral position.
This electric heating tube scope of application: the two power electric heating tubes of the flange form of new construction are applicable to horizontal liner horizontal electric heater popular on the present market.Because hot water density is lower than cold water density, so the heating tube power that is positioned at the bottom of this structural design can reach the requirement of the whole courage water of heating, satisfies the requirement of water heater storage-type heating, and the heating tube power that is positioned at the top can reach the requirement of heating top layer water.Water heater generally is to use the electric heating tube structure of the two heating tubes of two independent electric heating tubes or flange form in order to reach the layering heats on the market now.Lower on the two power heating tube costs of the single tube flange form of new construction than the above two structures, so market prospects are widely arranged.
In addition to the implementation, all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
