Abstract
The utility model relates to a bending double-layer water-electricity separated type heating tube, which is used for a horizontal water heater or a vertical water heater; the utility model overcomes the defect that a ceramic water-electricity separated heating tube is unsafe in the prior art. The utility model has the technical proposal that a bending double-layer separated heating and the padding of magnesium oxide insulating powder in a stainless steel inner sleeve and a stainless steel outer sleeve are adopted; an electric heating wire is placed along the inner wall of the stainless steel inner sleeve in a spiral mode. The utility model has the advantages of quick heat dispersion, long service life of the electric heating wire, high heating efficiency, no electrical leakage, high safety and full application of capacity of an inner bag; the utility model has development prospects.
Description
The utility model relates to a kind of electric calorifie installation, the double-deck water power isolated form of specifically a kind of bending heating tube.
Popular in the market water power isolated form heating tube great majority are that ceramic water power is isolated heating tube, and it leaves several straight troughs by ceramic Cylinder along outer garden, in the heating wire embedded groove, adds the stainless steel insulation blocking sleeve, makes with water and isolates.The weakness that this ceramic water power is isolated heating tube is: (1) ceramic heat conductivility is extremely low, and only by several the outside radiations heat energies of narrow notch in garden post surface, heat energy loss is big, and the heat efficiency is low.(2) if heating wire fusing is hit by a bullet out from ceramic body easily, directly contact, cause electric leakage with stainless steel sleeve.(3) because ceramic water power isolation heating tube is straight shape all, when being used for the horizontal type water heater, often insert inner bag from the center, termination, cause inner bag bottom water still can't heat, generally there is 1/3 capacity to be always cold water, make the inner bag capacity can't bring into play due effect.(4) overcoat is welded by stainless steel, very easily is subjected to various ion etchings in the water, after using after a while, in case corruption is worn, will leak electricity, and is very dangerous.By today, fail to provide not only safety but also suitable water power isolated form heating tube on the market.
The purpose of this utility model is at weak point of the prior art, and provide a kind of safe, be fit to the horizontal type water heater, or vertical water heater wherein uses the heat insulation heating tube of the double-deck water power of bending.
The technical solution of the utility model is: heating tube has the heating wire of two groups of different capacities, place along cover inwall in the stainless steel with the twin-feed spiral form, pad magnesium oxide insulating powder in the cover in stainless steel, compacting, heating wire does not contact with the inner sleeve, the heating wire termination is connected with conductor stretches out outside the steel bushing, the outer one deck stainless steel outer sleeve that adds again of cover in the stainless steel, also fill up magnesium oxide powder between the interior overcoat, compacting, interior overcoat is isolated fully, and the porcelain ring passes three conductors and embeds the electrothermal tube termination, sealing, the termination of the conductor binding post of burn-oning again is used for wiring, pallet and heating tube welding, heating tube are the double-deck water power isolated forms of bending, and it is 500 watts and 1000 watts that heating tube has the heating wire of two groups of different capacities.
The utility model has following advantage compared to existing technology:
(1) heating wire is to place with spiral form along interior cover inwall, so rapid heat dissipation, can prolong the heating wire life-span.(2) the magnesium oxide heat conductivility is higher than pottery far away, so heat efficiency height.(3) heating wire is to be placed in the magnesium oxide of compacting, though fusing, can be with the contact of interior cover, and interior cover also has one deck magnesium oxide insulating barrier outward, will never cause electric leakage.(4) overcoat is made by heavy wall, and is not perishable.Even cover is isolated in long-term the use caused rotten leakage water, also had, still safety.(5) heating tube can curve required angle as required, horizontal type water heater liner bottom water also can be heated, thereby the inner bag capacity can be used fully.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structural representation of the utility model heating tube
With regard to an embodiment, in conjunction with the accompanying drawings the utility model is elaborated below:
Heating tube in the horizontal type water heater, form with 1000 watts of two groups of different heating wire by 500 watts, heating wire is placed along cover 5 inwalls in the stainless steel with the twin-feed spiral form, magnesium oxide insulating powder 6 in stainless steel, filling up in the middle of the cover, through compacting, heating wire is not contacted with the inner sleeve, and the heating wire termination is connected with conductor 3 stretches out outside the steel bushing, the outer one deck stainless steel outer sleeve 4 that adds again of cover in the stainless steel.Between the interior overcoat also pad go up magnesium oxide powder, and through compacting, overcoat is isolated fully in making, porcelain ring 2 passes three conductors and embeds the electrothermal tube terminations, and is sealed, the termination of conductor 3 binding post 1 of burn-oning again is used for wiring, pallet 8 and heating tube welding.
This heating tube is the double-deck water power isolated form of bending, and the rational method of cold water from the bottom heating can be accomplished in crooked deeply bottom in the termination, and heating tube also can be used for vertical water heater and other type of electrical apparatus.
Claims (2)
1, a kind of heating tube, it is characterized in that: the heating wire (7) that two groups of different capacities are arranged, place along cover (5) inwall in the stainless steel with the twin-feed spiral form, pad magnesium oxide insulating powder (6) in the cover (5) in stainless steel, compacting, heating wire does not contact with the inner sleeve, the heating wire termination is connected with conductor (3) stretches out outside the steel bushing, the outer one deck stainless steel outer sleeve (4) that adds again of cover in the stainless steel, also fill up magnesium oxide powder between the interior overcoat, compacting, interior overcoat is isolated fully, and porcelain ring (2) passes three conductors and embeds the electrothermal tube termination, sealing, the termination of conductor (3) binding post (1) of burn-oning again is used for wiring, and pallet (8) and heating tube welding, heating tube are the double-deck water power isolated forms of bending.
2, heating tube according to claim 1 is characterized in that: the heating wire of two groups of different capacities is 500 watts and 1000 watts.
