Further, " C " type opening, the second airtight end cap and the second flange end cap of the described second inner bag centre circle respectively with the first inner bag centre circle in inside or outside weldings fix, forming cross section is two inner bags of " 8 " type.
Further, described first inner bag and the second inner bag inside are provided with enamel layer, and enamel layer covers all welding positions.
Further, the described first inner bag limbers is provided with flange.
Further, the centre circle cross section of described second inner bag is " D " type, " D " type vertical edge place face is provided with the first inner bag limbers and adapts to the limbers cooperates, reach the second airtight end cap and the second flange end cap docks with the second inner bag centre circle respectively and in inside or outside weldings fix.
Further, the described second inner bag centre circle, the second airtight end cap and the second flange end cap respectively with first inner bag in inside or outside weldings fix, forming cross section is two inner bags of " 8 " type.
Further, the described first inner bag limbers and the second inner bag limbers are respectively equipped with the flange that butt joint cooperates and welding is fixing.
Further, the described first inner bag limbers and the second inner bag limbers are coated with O-ring seal in the junction, and are spirally connected by cored screw and nut.
Further, described first inner bag and the second inner bag inside are provided with enamel layer, and enamel layer covers all welding positions.
The utility model compared with prior art, its beneficial effect is: improve the syndeton between two inner bags, layout simultaneously rationally the welding procedure order, technology is simple, weld seam is few, hot and cold water mixes, go out hot water rate height, corrosion-resistant, long service life and cost are low, eliminate quality and potential safety hazard, be suitable for promoting the use of of electric heater.
In order to understand the utility model more clearly, set forth the specific embodiment of the present utility model below with reference to description of drawings.
