Abstract
The utility model discloses an electric heating tube component which comprises a heating tube comprising a metal tube; an electric heating wire is communicated to the inside of the metal tube through an insulating and heat-conducting material; and an enamel protection layer is covered on the outer surface of the metal tube of the heating tube. The utility model can completely block the contact of the liquid and metal of the heated tubes because the enamel protection layer is completely covered on the outer surface of the metal tube of the heating tube, improves the erosion resistance on the surface of the metal tube, and prolongs the service life of the electric heating tube. The electric heating tube component can be widely applied in the fields of households and industries.
Description
Technical field
The utility model relates to a kind of electric heating tube component, the outer field electric heating tube component of especially a kind of band enamel.
Background technology
At present, the electric heating tube component of electric heater use at present, because direct and water Contact Heating, and contain various impurity such as Cl-ion, Ca2+ in the water, in heating process, electrical heating elements adsorbs various impurity easily and produces corrosion, and gathers incrustation scale.Like this, not only shorten the life-span of electric heating tube, and after using a period of time, the efficiency of heating surface will reduce obviously.
It is to be coated with an enamel coating and to prevent above-mentioned situation on the metal tube surface that a kind of heating tube is arranged at present on the market, though tool has certain effect,, this enamel coating is not the whole outer surfaces that are covered in metal tube, after the long-time use of this product, incrustation scale still can be gathered in its end.In addition, because this heating tube generally all will carry out thermometric and control its work, temperature tube is not far apart from heating tube, and the problem of incrustation scale is gathered in the same existence of the temperature tube of product at present, and after long-time the use, its thermometric is inaccurate, uses imperfection.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model has been to provide a kind of electrothermal tube assembly reliable, simple in structure that uses.
The another one purpose is to provide a kind of its heating tube and the temperature tube all can service-strong electrothermal tube assembly.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of electric heating tube component comprises heating tube, and heating tube includes metal tube, is connected with heating wire by insulating heat-conduction material within the metal tube, and the outer surface of the metal tube of described heating tube is coated with the enamel protective layer.
Further, described heating tube is installed on the flange, and temperature tube also is installed on this flange.Wherein, as preferred implementation, the outer surface of described temperature tube is coated with temperature tube enamel protective layer.Further, the lower surface of described flange is coated with flange enamel protective layer.
The beneficial effects of the utility model are: owing to all be coated with the enamel protective layer at the metal tube outer surface of heating tube; can block comprehensively and be heated contacting of pipe liquid and metal; improved the corrosion resistance on metal tube surface; can reduce simultaneously the depletion rate of anode stub in the water heater liner, improve the useful life of electrothermal tube.Further, the outer surface of the temperature tube of together installing with heating tube is coated with the enamel protective layer equally, makes that prolong the useful life of temperature tube, thermometric is accurate.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the sectional structure schematic diagram of the utility model execution mode one;
Fig. 2 is the structural representation of the utility model execution mode two.
Embodiment
With reference to Fig. 1; a kind of electric heating tube component of the present utility model comprises heating tube 1, and heating tube 1 includes metal tube 10; be connected with heating wire 12 by insulating heat-conduction material 11 within the metal tube 10, the outer surface of the metal tube 10 of described heating tube 1 is coated with enamel protective layer 2.Wherein, the ferrous metal pipe that this metal tube 10 can be a given shape as shown in Figure 1, certainly, and the another kind of shape that this metal tube also can be as shown in Figure 2, the two ends of ferrous metal pipe are extruded with the lead end 13 that is connected with heating wire 12.
Further; for ease of the heating tube assembly is installed on the inner container of electric water heater; described heating tube 1 is installed on the flange 3; in addition, thereby can detect of the work of the real time temperature of institute's heating liquid for the while, on this flange 3 temperature tube 4 is installed also by other devices control heating tubes; and; further, the outer surface of described temperature tube 4 is coated with temperature tube enamel protective layer 5, plays the effect of further temperature tube 4 being carried out the antiscale protection.
In addition, further, the lower surface of described flange 3 is coated with flange enamel protective layer 6.
Because parts of the present utility model have covered the enamel protective layer comprehensively, avoided the corrosion and the dissolving of electric heating tube metal surface and further temperature tube and mounting flange have been protected, opened up newly the application of electrothermal tube assembly.
Certainly, the utility model is not limited to above-mentioned execution mode, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection range of the present utility model.
