Abstract
The utility model discloses a water heater with an enamel inner container. The water heater with the enamel inner container comprises an inner container sealing head and an inner tank communication component, wherein the inner tank communication component is sleeved on the inner container sealing head, an external interface gap formed by the inner tank communication component and the inner container sealing head is connected through a welding process, and an inner interface gap formed by the inner tank communication component and the inner container sealing head is covered by inner container enamel. The water heater with the enamel inner container has the advantage of being simple in manufacturing process.
Description
Technical field
The utility model relates to field of water heaters, relates in particular to a kind of water heater that adopts enamel inner container.
Background technology
Pot-type boiler is made up of shell, inner bag, the water inlet pipe that is connected with inner bag, outlet pipe, blow-off pipe and heater usually.Wherein, inner bag with the syndeton of outside on, normally be connected with inner bag communication means (such as water inlet pipe, outlet pipe, blow-off pipe, inner bag flange) by the liner end enclosure that forms behind the inner bag piercing and flanging.Heater is connected with the inner bag flange by the heater flange.
See also Fig. 1, Fig. 2 and Fig. 3, after inner bag flange 15 inserts liner end enclosure 14, external interface slit A is adopted the carbon dioxide welding, internal interface slit B is adopted the argon arc welding, after welding is finished, the solder joint polishing of internal interface slit B is level and smooth, carry out enamel again, to guarantee the adhesive force of enamel layer 19.Be provided with sealing ring 13 between inner bag flange 15 and the heater flange 12.Gland 11 and inner bag flange 15 be by being threaded, thereby heater flange 12 is fixed.
Yet above-mentioned inner bag syndeton need adopt the argon arc welding and need butt welding point to polish in manufacture process internal interface slit B, because internal interface slit B in inner bag inside, welds and polishing is all very inconvenient, causes the manufacturing process complexity.
The utility model content
In order to solve the problems referred to above of prior art, be necessary to provide a kind of manufacturing process simple heating device.
The technical scheme that the utility model technical solution problem provides is:
A kind of water heater that adopts enamel inner container, it comprises liner end enclosure and inner bag communication means, the inner bag communication means is placed on the liner end enclosure, the inner bag communication means adopts welding procedure to be connected with the external interface slit that liner end enclosure forms, and the internal interface slit that inner bag communication means and liner end enclosure form is covered by inner bag enamel.
Wherein, described inner bag communication means is a water inlet pipe.
Wherein, described inner bag communication means is an outlet pipe.
Wherein, described inner bag communication means is a blow-off pipe.
Wherein, described inner bag communication means is the inner bag flange.
Wherein, the water heater of described employing enamel inner container further comprises gland and heater flange, and gland and inner bag flange be by being threaded, thereby the heater flange screw is fixed.
Wherein, the water heater of described employing enamel inner container further comprises the sealing ring that is arranged between inner bag flange and the heater flange.
Wherein, the water heater of described employing enamel inner container further comprises the sealing ring between gland and the inner bag flange.
Compared to prior art, in the syndeton of water heater liner of the present utility model, inner bag communication means (water inlet pipe, outlet pipe, blow-off pipe, inner bag flange) all is to be placed on the liner end enclosure, then fairly simple carbon dioxide welding is adopted in the external interface slit, inner bag is carried out enamel, thereby cover the internal interface slit, omitted argon arc welding procedure and technique for grinding the internal interface slit, reduce the complexity of making, and saved manufacturing cost.

The specific embodiment
As shown in Figure 4, in a kind of embodiment of the present utility model, inner bag flange 25 and liner end enclosure 24 peripheries are outside to be connected, inner bag flange 25 is placed on liner end enclosure 24 after, adopt carbon dioxide to weld to external interface slit A.Inner bag is carried out enamel, C place, internal interface slit is covered, enamel is even, forms enamel layer 29.Be provided with sealing ring 23 between inner bag flange 25 and the heater flange 22.Gland 21 and inner bag flange 25 be by being threaded, thereby heater flange 22 is fixed.Be provided with sealing ring 26 between gland 21 and the inner bag flange, its objective is in order to prevent the aqueous vapor corrosion pitch thread age of a draught animal.
In other embodiment of the present utility model, outlet pipe can be placed on liner end enclosure after, the carbon dioxide welding is adopted in the external interface slit; Inner bag is carried out enamel, and the place covers with the internal interface slit, and enamel is even, forms enamel layer; After water inlet pipe can being placed on liner end enclosure, the carbon dioxide welding is adopted in the external interface slit; Inner bag is carried out enamel, and the place covers with the internal interface slit, and enamel is even, forms enamel layer; After blow-off pipe can being placed on liner end enclosure, the carbon dioxide welding is adopted in the external interface slit; Inner bag is carried out enamel, and the place covers with the internal interface slit, and enamel is even, forms enamel layer.
Compared to prior art, in the syndeton of water heater liner of the present utility model, inner bag communication means (water inlet pipe, outlet pipe, blow-off pipe, inner bag flange) all is to be placed on the liner end enclosure, then fairly simple carbon dioxide welding is adopted in the external interface slit, inner bag is carried out enamel, thereby cover the internal interface slit, omitted argon arc welding procedure and technique for grinding the internal interface slit, reduce the complexity of making, and saved manufacturing cost.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
