Abstract
The utility model relates to a liner of a water-storage electric water heater, which comprises an electrothermal duct, a water inlet duct, a water outlet duct, and two or more than two column-shaped liners arranged side by side, A honeycomb duct is arranged between the liners, and the connection of the both end caps of the single liner with a barrel body, and the honeycomb duct with the barrel body is sealed connection in a mechanical clamping mode. The manufacture of the liner of the water-storage electric water heater and the connection with the honeycomb duct and the water inlet duct and the water outlet duct all adopt sealed connection in the mechanical clamping mode. The traditional welding procedure is replaced, the phenomenon of water leakage of the liner of water-storage electric water heater because of the welding quality and the environmental influence is thoroughly solved, and the production quality is enhanced. The utility model has the advantages that the simple structure and reasonable, and the processing, the manufacture, the installation and the maintenance are all very convenient.
Description
The utility model relates to a kind of water-storage electric heater inner bag.
Existing water-storage electric heater kind is more, and structure is different.No matter it is its inner bag is single, still two or more side by side; No matter its material is a stainless steel, or the enamelling sheet steel coating; All be earlier with being welded after the metal material processing.Owing to influenced by welding procedure and material, environment for use etc., after use a period of time, the problem of welding seam leakage more or less all can appear, and there is certain potential safety hazard, and influences the service life of inner bag.As existing a kind of side-by-side inner bag, be provided with a plurality of mozzles between its inner bag, and mozzle also is to adopt to be welded to connect with being connected of inner bag.Because the stress that produces when liner material punch forming and high-temperature soldering can not in time discharge, the temperature difference that produces between the inner bag during use and water, atmospheric pressure add the stress that upper inner-liner self does not discharge, and very easily cause the weld bond explosion, and formation is leaked.The utility model also is to the further improvement of my 992353459 patents and perfect.
The purpose of this utility model aims to provide a kind of rational in infrastructure, water-storage electric heater inner bag that need not be welded to connect, to overcome the deficiencies in the prior art part.
A kind of water-storage electric heater inner bag by this purpose design, comprise electrothermal tube, water inlet pipe, outlet pipe, the two or more column inner bags that are arranged side by side, be provided with mozzle between two inner bags, its architectural feature is all to be that the mechanical grip of no-welding type is tightly connected being connected of two end cap and cylindrical shell, mozzle and being connected of inner bag cylindrical shell of single inner bag.
Described water inlet pipe and water outlet pipe and being connected of inner bag cylindrical shell also can be that the mechanical grip of no-welding type is tightly connected.Inner bag cylindrical shell two ends are provided with flange; End cap is connected by ring flange, sealing ring and fishbolt with the inner bag cylindrical shell.The mozzle two ends are provided with gas thread, are tightly connected by nut and sealing ring and two inner bag cylindrical shells.The joint of water inlet pipe and water outlet pipe is provided with gas thread, is tightly connected by nut and sealing ring and inner bag cylindrical shell.
Another kind of water-storage electric heater inner bag by this purpose design comprises inner bag, electrothermal tube, water inlet pipe and outlet pipe, and its architectural feature is that the two end cap of inner bag and the mechanical grip that is connected to no-welding type of cylindrical shell are tightly connected; The cross section of inner bag is circular, oval, non-circular, square or polygon.Inner bag cylindrical shell two ends are provided with flange; End cap is connected by ring flange, sealing ring and fishbolt with the inner bag cylindrical shell.
The making of this inner container of electric water heater and all adopt mechanical grip to be tightly connected with being connected of mozzle, water inlet pipe and water outlet pipe, replaced traditional welding procedure, thereby thoroughly solved inner container of electric water heater because of the drainage that welding quality and environment for use influence cause, improved product quality.It is simple and reasonable for structure, and processing and fabricating and installation and maintenance are all very convenient.
Following structure drawings and Examples are further described the utility model.
