Description
Technical field
The utility model relates to a kind of electric heater unit, is used for the heating of solar water heater auxiliary electrical.
Background technology
Majority solar energy producer is to realize the auxiliary electrical heating function, and electric heater unit is installed.In the Solar Heater Market, there are two kinds of electric heater units now.A kind of is the electric heater unit of threaded flange, needs to weld threaded fixture on the water tank, then electric heater is screwed on; Welding position on this solar water heater can be corroded for a long time, causes radiator leak, and electric heater touches water and causes security incident.Another kind is directly electric heater to be inserted in the vacuum pore.Seal badly, leak easily, and fixing insecure.
Summary of the invention
The purpose of this utility model is to overcome the defective that above-mentioned prior art exists, and provides a kind of simple in structure, good seal performance, the solar-electricity heater of exempting to weld of long service life.
The technical solution of the utility model is: the solar-electricity heater that this kind exempts to weld, comprise the electric heating tube assembly, the fixing flange assembly that places the inner water tank tapping of electric heating tube assembly, it is characterized in that, described flange assembly comprises the heating tube upper flange, heating tube lower flange and the seal gasket between the two, at the heating tube upper flange, the heating tube lower flange, the seal gasket middle part is provided with the through hole of concentric, one bolt is by the heating tube lower flange, seal gasket, the heating tube upper flange is fastened as one by nut, at the heating tube upper flange, the heating tube lower flange, also be provided with two electric heating tube assembly fixing holes on the seal gasket, the electric heating tube assembly is positioned at the said fixing hole.
The further technical scheme of the utility model is:
Also be provided with a heating tube temperature control sleeve pipe fixing hole on heating tube upper flange, heating tube lower flange, seal gasket, this hole is built-in with heating tube temperature control sleeve pipe, is provided with the temperature controller sleeve pipe rubber stopper of band centre bore in the outer end of heating tube temperature control sleeve pipe.
Described heating tube upper flange is provided with and coats the outer peripheral flange of seal gasket.So that when fastening bolt, make being radially expanded of seal gasket concentrate on the junction of seal gasket and inner water tank, thereby improve sealing.
The beneficial effects of the utility model are, compare with prior art, the utlity model has reasonable in designly, simple in structure, exempt from welded and installed, and fixed.There are not characteristics such as potential safety hazard in good airproof performance.The seepy question of thoroughly having avoided the erosion because of surrounding medium to bring.Therefore, on solar water heater, have good value for applications.
Description of drawings
Figure is a front view of the present utility model.
Among the figure; 1 heating tube upper flange, 2 nuts, 3 bolts, 4 temperature controller sleeve pipe rubber stoppers, 5 seal gaskets, 6 heating tube lower flanges, 7 heating tube temperature control sleeve pipes, 8 electric heating tube assemblies.
The specific embodiment
As shown in the figure.
The solar-electricity heater that this kind exempts to weld mainly comprises electric heating tube assembly 8, fixedly flange assembly two parts that place the inner water tank tapping of electric heating tube assembly.The flange assembly is used for fixing and supports electric heating tube assembly 8.
Described flange assembly comprises heating tube upper flange 1, heating tube lower flange 6 and the seal gasket 5 between the two.Be provided with the through hole of concentric at heating tube upper flange 1, heating tube lower flange 6, seal gasket 5 middle parts, a bolt 3 is fastened as one by nut 2 by heating tube lower flange, seal gasket, heating tube upper flange.On heating tube upper flange 1, heating tube lower flange 6, seal gasket 5, also be provided with two electric heating tube assembly fixing holes.The main body of electric heating tube assembly 8 is the U type, and the upper bend part of electric heating tube assembly 8 places respectively in the electric heating tube assembly fixing hole.
On heating tube upper flange 1, heating tube lower flange 6, seal gasket 5, also be provided with a heating tube temperature control sleeve pipe fixing hole, this hole is built-in with heating tube temperature control sleeve pipe 7, be provided with the temperature controller sleeve pipe rubber stopper 4 of band centre bore in the outer end of heating tube temperature control sleeve pipe, temperature controller sleeve pipe rubber stopper 4 is used for fixing the temperature controller outlet.
Coat the outer peripheral flange of seal gasket on the heating tube upper flange 1.So that when fastening bolt, make being radially expanded of seal gasket 5 concentrate on the junction of seal gasket and inner water tank, thereby improve sealing.
Solar-electricity heater processing and fabricating of exempting to weld of the present utility model is very simple and convenient, except that the described technical characterictic of specification, is the known technology of those skilled in the art.
