Abstract
A water-sealed inner container with internal and external weld seams for a water heater is characterized in that an opening end (2), a middle barrel section and a non-opening end (10) of the inner container are made of a common steel plate or a stainless steel plate, the opening end (2) and the non-opening end (10) are welded at two ends of the middle barrel section (6), a water inlet short pipe and a water outlet short pipe (7) are welded at a small hole at the lower part of the middle barrel section (6), a flange fixing seat (1) is welded around the opening end (2), then a layer of non-porous waterproof glue is uniformly coated inside and outside all the weld seams, the weld seams comprise an end annular weld seam, a middle section straight weld seam and a water inlet pipe and water outlet pipe weld seam, and after water is injected into the inner container, the non-porous waterproof glue layers prevent water from contacting with the weld seams, and even enamel of the weld seams are exposed or stainless steel.
Description
Technical Field
The invention belongs to accessories of electric water heaters, and particularly relates to an inner container with inner and outer weld seals for a water heater.
Background
At present, the inner container for manufacturing the water storage type electric water heater is generally divided into two types, one type is that the inner surface of the inner container is enameled by using a common steel plate so as to achieve the purpose that the inner container is filled with water for a long time and is not rusted after the water is injected into the inner container; the other is to use stainless steel plate to make the inner container. However, after the two inner containers are filled with water, the welding seams of the two inner containers have defects: when the inner surface of the inner container is enameled, the welding seam is not easy to make the enamel uniform, so that a plurality of places (particularly convex and sharp parts) can be exposed, and the places can rust and rot under the long-term soaking of water, and finally water leakage is caused; the inner container made of the stainless steel plate is not provided with the original stainless steel anti-rust capability because the metallographic phase of the stainless steel at the welding seam is changed by the high temperature generated by welding during welding, so the inner container made of the stainless steel is often corroded and leaks water at the welding seam due to rusting.
The invention provides a solution, and provides an inner container of an inner and outer welding seam water seal for a water heater. The inner container can be made of a common steel plate or a stainless steel plate, the welding seam can not be rusted and corroded after the inner container is soaked with water for a long time, and the service life of the inner container can be greatly prolonged.
Disclosure of Invention
The invention is realized by the following steps: the inner container opening end, the barrel middle section and the non-opening end are made of common steel plates or stainless steel plates, the opening end and the non-opening end are welded at two ends of the barrel middle section, a short water inlet and outlet pipe is welded at a small hole at the lower part of the barrel middle section, and a flange fixing seat is welded around the opening end. And then uniformly coating a layer of non-porous waterproof glue inside and outside all the welding seams, wherein the welding seams comprise end circular welding seams, middle section straight welding seams and water inlet and outlet pipe welding seams. After water is injected into the inner container, the weld seams are coated with uniform nonporous waterproof glue which prevents water from contacting the weld seams, and the weld seams are not rusted to cause corrosion and water leakage even if the enamel is not uniform and the weld seams are exposed or the stainless steel weld seams are not uniform.
The foaming agent is inserted into the shell of the water heater, and then the foaming agent is injected between the inner container and the shell to generate foam for filling so as to form the heat insulation layer.
Drawings
FIG. 1 is a front sectional view of the present invention.
In the figure: 1. a flange fixing seat; 2. an open end; 3. the annular welding seam of the outer end head is provided with a non-porous waterproof adhesive; 4. the annular welding seam of the inner end head is provided with a non-porous waterproof glue; 5. the straight welding seam of the inner middle section has no hole and waterproof glue; 6. a middle section of the barrel; 7. a short water inlet and outlet pipe; 8. the weld joint of the short pipe with water inlet and outlet is provided with a hole-free waterproof glue; 9. the weld joint of the short pipe with water inlet and outlet is provided with a hole-free waterproof glue; 10. a non-opening end.
Detailed Description
The invention is realized by the following steps: the inner container opening end (2), the barrel middle section and the non-opening end (10) are made of common steel plates or stainless steel plates, the opening end (2) and the non-opening end (10) are welded at two ends of the barrel middle section (6), a water inlet short pipe (7) and a water outlet short pipe (7) are welded at a small hole at the lower part of the barrel middle section (6), and a flange fixing seat (1) is welded around the opening end (2). And then uniformly coating a layer of non-porous waterproof glue inside and outside all the welding seams, wherein the welding seams comprise end circular welding seams, middle section straight welding seams and water inlet and outlet pipe welding seams. After water is injected into the inner container, the weld seams are coated with uniform nonporous waterproof glue which prevents water from contacting the weld seams, and the weld seams are not rusted to cause corrosion and water leakage even if the enamel is not uniform and the weld seams are exposed or the stainless steel weld seams are not uniform.
