Abstract
The utility model relates to a kind of water-heater water tank with double-side sandwich, belongs to technical field of water heaters.This water tank comprises the cylindric inner bag forming closed container and the chuck with cancave cambered surface of fitting with inner bag outer round surface, the inner surface of described chuck cancave cambered surface extends expansion limit towards both sides circumference, the expansion limit of described both sides has respectively one group of assembly hole spaced apart, the fixed leg of the position fixed radial extension of the corresponding described assembly hole of described inner bag outer round surface, described assembly hole extends along described outer round surface generatrix direction, the irregularly-shaped hole that the large other end is little in one end, be connected with the transition limit away from expansion limit by the straight flange on contiguous expansion limit between the large end of described irregularly-shaped hole and small end.Due between chuck with inner bag without the need to welding, therefore the anticorrosive coat of enamel layer and so in inner bag is not damaged, and the structure of assembly hole is not only easy to assembly, and ensure that fitting tightly of inner bag and chuck.
Description
Technical field
The utility model relates to a kind of water tank of water heater, and especially a kind of water-heater water tank with double-side sandwich, belongs to technical field of water heaters.
Background technology
There is the early stage typical structure of the water-heater water tank (its main body is commonly called as inner bag) of heat exchange interlayer for disclosed in the Chinese utility model patent of application number 01261923.X.Afterwards, application number be 201210088691.6 Chinese invention patent application disclose a kind of water heater interlayer water tank and processing method thereof.
In recent years, in order to meet the standard about ensureing the safety of water source, double-layer interlayer water heater liner comes out, and its typical structure is for disclosed in the Chinese patent of application number 201020694399.5.Although this kind of double sandwich water heater liner class structure is obviously different from single sandwich, but the combination of interlayer and inner bag cannot use for reference the method for 201210088691.6, therefore still based on traditional welding procedure, be only ensured that the full weld of sealing changed the less edge intermittent weld of heat or spot welding into by originally needing.But facts have proved no matter adopt intermittent weld or spot welding, the hot-spot of weldering place still can cause enamel to occur crack, and its antiseptic property is weakened greatly.Therefore, the damage of exempting from of double-layer interlayer enamel inner container is combined into one technical barrier.
Summary of the invention
The purpose of this utility model is: for above-mentioned prior art Problems existing, proposes a kind of easy for installation, can ensure the water-heater water tank with double-side sandwich that double sandwich and inner bag intimate surface are fitted.
In order to reach above object, the water-heater water tank with double-side sandwich of the present utility model comprises the cylindric inner bag forming closed container and the chuck with cancave cambered surface of fitting with inner bag outer round surface, the inner surface of described chuck cancave cambered surface extends expansion limit towards both sides circumference, the expansion limit of described both sides has respectively one group of assembly hole spaced apart, the fixed leg of the position fixed radial extension of the corresponding described assembly hole of described inner bag outer round surface, described assembly hole extends along described outer round surface generatrix direction, the irregularly-shaped hole that the large other end is little in one end, be connected with the transition limit away from expansion limit by the straight flange on contiguous expansion limit between the large end of described irregularly-shaped hole and small end.
Due to assembling process chuck with between inner bag without the need to welding, therefore the anticorrosive coat of enamel layer and so in inner bag is not damaged, and the structure of assembly hole is not only easy to assembly, and ensure that fitting tightly of inner bag and chuck.
During actual fabrication, the width of described small end and the diameter compatible of described fixed leg, the straight section that especially described transition limit is parallel to straight flange by the circular hole arc section held greatly and small end is connected and composed by transition arc, and the laminating locating effect like this during assembling is better.
It is that described chuck is fitted in the outer round surface of horizontal positioned inner bag from the bottom to top that the utility model further improves, and form semi-surrounding structure, communicating pipe is equipped with on the top of described chuck.

Detailed description of the invention
Embodiment one
The present embodiment is a kind of horizontal water heater water tank with double-side sandwich, its structure as shown in Figure 1, Figure 2 and Figure 3, comprises and to form the cylindric inner bag 1 of closed container after cylindrical tube welds with two ends end socket and have the chuck 2 of cancave cambered surface of fitting with inner bag outer round surface.Chuck 2 is fitted in the outer round surface of inner bag 1 from the bottom to top, forms semi-surrounding structure.The inner surface of chuck 1 cancave cambered surface extends expansion limit 2-1 towards both sides circumference, the expansion limit 2-1 of both sides has respectively one group of assembly hole 2-2 spaced apart.The position of the corresponding assembly hole 2-2 of inner bag 1 outer round surface is welded and fixed the radial fixed leg 3 extended.Assembly hole 2-2 extends along outer round surface generatrix direction, the irregularly-shaped hole that the large other end is little in one end, is connected between the large end of this irregularly-shaped hole and small end by the straight flange 2-3 of contiguous expansion limit 2-1 with the transition limit away from expansion limit 2-1.As shown in Figure 4, the straight section that this transition limit is parallel to straight flange 2-3 by the arc section and small end of holding greatly circular hole is connected and composed by transition arc r.The width of small end and the diameter compatible of fixed leg 3.In figure, 7,8 are the inlet pipe of chuck 2 respectively and go out pipe, and 9,10 is water inlet pipe and the outlet pipe of inner bag 1 respectively.
In addition, in the air impact chuck cavity of chuck 2 during tank liquid, fill heat exchange medium, communicating pipe 4 is equipped with on the top of chuck 2, and air during filling liquid can be made like this to drain in communicating pipe, thus ensures to fill medium in chuck.
During assembling, chuck is had lower supreme fasten with inner bag after, each fixed leg is made to be each passed through corresponding assembly hole, make the displacement to axial of chuck and inner bag afterwards, allow fixed leg under the guiding function on transition limit, progress into small end, thus the cancave cambered surface of chuck and the outer round surface of inner bag are fitted tightly, then take relative fixation.Be understood that, due between chuck with inner bag without the need to welding, therefore avoid the damage to enamel layer in inner bag, assembly hole and fixed leg in place, very convenient by holding greatly, move to small end afterwards and then ensure that fitting tightly of inner bag and chuck.
Embodiment two
The present embodiment is a kind of vertical water heater tank with double-side sandwich, and as shown in Figure 5 and Figure 6, its concrete structure is not difficult to know by inference from embodiment one, therefore does not describe in detail.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
