In use get rusty in base, the measure that prior art is taked is in base endoporus, fill an antirust liner or base inwall coating enamel antirust coat.But liner or enamel layer all can not prolong and to the thread segment of outer end of hole in base, therefore can not be formed and effectively hide protection comprehensively, base internal rust and rust water still can not be stoped to flow out.
In addition, above-mentioned prior art is when the extension tube attached that replacing reach is shorter, and the end face of extension tube attached cannot be fitted with the outer face of liner, and therefore original basic sealing state is not hard to keep, and more easily occurs that rust water flows out phenomenon.
Summary of the invention
Primary and foremost purpose of the present invention is: the shortcoming and defect existed for above-mentioned prior art, proposes a kind of antirust base structure that can conscientiously suppress corrosion to avoid producing rusty stain, provides the water heater adopting this structure simultaneously.
Further aim of the present invention is: propose a kind ofly adapt to the antirust base structure of different reach extension tube attached and adopt the water heater of this structure.
In order to reach above primary and foremost purpose, the basic technical scheme of antirust base structure of the present invention is: comprise the antirust material bushing pipe (5) that embedding is fixed on cylinder board (6) tapping, described bushing pipe (5) tightly overlaps outer end outward and has the base (2) connecting internal thread, described base (2) overcoat has the sheath (1) of antirust material, the inner of described sheath (1) has extension flange, the antirust material conduit (4) of described bushing pipe (5) interior plug-in mounting, the external port of described conduit (4) has and extends out flange, described extending out on flange clamps the elastic thread sealing shroud (3) that cross section is C shape, the cylindrical of described thread seal cover (3) has the projection embedding internal thread groove.
Because sheath the inner of the present invention has extension flange, block along base outer wall seepage channel, therefore can effectively avoid rust water to flow out.Meanwhile, bushing pipe not only by with conduit fit tightly the effect played the first order and seal, and to extend out on flange elastic thread sealing shroud also by with extension tube attached inner face gluing, sealing while, embed in the internal thread groove of base by elastomeric radial, define the sealing of mazy second level, therefore effectively can block rust water and exosmose.As can be seen here, the present invention has all carried out rationally effective improvement to external and internal compositions simultaneously, therefore effectively can solve the difficult problem that rust water exosmoses.
In order to reach further object, between the inner face that bushing pipe of the present invention (5) outer face and conduit (4) extend out flange (4-1), axial elasticity part is housed.
Like this, even if the reach of extension tube attached changes in certain limit, under the effect of axial elasticity part, can ensure that elastic thread sealing shroud and extension tube attached end face fit tightly all the time, and pressurized produces and embeds the distortion of base, thus remain valid and block the sealing function that rust water exosmoses.

Detailed description of the invention
Embodiment one
The present embodiment adopts the water heater of antirust base structure as shown in Figure 1, comprises water heater liner, shell 8 that cylinder board 6 surrounds, and is filled in the insulating foam layer 7 between inner bag and shell.The tapping that inner bag is communicated with exterior line is equipped with antirust base structure F.The outer end of this antirust base structure is substantially concordant with shell 8, the case ring 9 of peripheral embedded flanging, and concrete structure as shown in Figure 2,3, comprises and embeds by inner cone end the antirust material bushing pipe 5 being fixed on cylinder board 6 tapping.The outer tight cover outer end of bushing pipe 5 has the base 2 of the connection internal thread of undergauge.The undergauge section cover of this base 2 outer end has the sheath 1 of plastic material.The inner of this sheath 1 has extension flange 1-1, is embedded in heat-insulation layer 7 during installation, even if accompany infiltration in heat-insulation layer, also can effectively stop it along base outer wall seepage flow.The end face section 1-2 covering base 2 outer face and the taper limes marginis section 1-3 embedding base 2 screw thread port chamfering is extended in the outer end of this sheath 1, therefore when being screwed into extension tube attached 10, its external screw thread inclined-plane will compress taper limes marginis section 1-3, thus more effectively avoid any rust water to exosmose (see Fig. 6).
