Abstract
The utility model relates to an electric heating tube assembly with a novel flange structure. The electric heating tube assembly comprises a stainless steel electric heating tube element and a stainless steel flange, a boss structure is arranged on the cylindrical side of the stainless steel flange, a seal ring for sealing is placed on the boss structure, the stainless steel flange and the stainless steel electric heating tube element are fixedly welded through nickel soldering paste and fluxes, and the stainless steel flange is formed by stamping and drawing of a stainless steel board. The electric heating tube assembly with the novel flange structure has the advantages that the novel flange structure is formed by stamping and drawing of the stainless steel board, the forming is easy, and the technology is mature and reliable; the boss design of the novel flange structure can meet requirements for dimensional accuracy of sealing structures of conventional brass flanges as well, and the sealing performance is not affected; both the stainless steel flange and the stainless steel electric heating tube element are made of stainless steel materials, so that the welding performance is improved greatly; the electric heating tube assembly is applied to mass welding of conventional brazing furnaces, the efficiency is improved, and the cost is saved; and the sealing performance of welding positions is superior, and surfaces are clean and smooth and not easy to rust.
Description
Technical field
The utility model relates to the electrothermal tube field, mainly is the electrothermal tube assembly of the band novel flange structure of the auxiliary heating of a kind of solar water heater usefulness.
Background technology
The electrothermal tube assembly of the common auxiliary heating of solar water heater usefulness adopts compositions such as brass flange 6 and stainless steel electrical heating tube element 3 in the market, by yellow gold scolder 7 brass flange 6 and stainless steel electrical heating tube element 3 is welded the electrothermal tube assembly of making (seeing shown in Figure 1) then.
Above the brass flange 6 that adopts of common electrothermal tube assembly, main purpose is to place sealing ring 5 in the boss structure position of brass flange 6, carries out effective seal with water heater container 4 and is connected, anti-sealing leakage.But brass material reaches the dimension precision requirement of required sealed step, complex procedures again because the limitation of its machining property generally need be carried out the drop stamping moulding earlier through machined.
Because brass flange 6 and stainless steel electrical heating tube element 3 need weld together, because brass has different thermal coefficient of expansions with stainless steel, welding performance difference is big, so to welding material, welding procedure, welding process have very high requirement in addition; At present welding material adopts the yellow gold composition usually, and not only price is high, and the welding procedure complexity, can only the one man operation, and the single-piece welding can not realize welding inefficiency in enormous quantities simultaneously; Face of weld easy oxidation blackout in welding back needs the extra cleaning process that increases simultaneously, causes the processing cost waste.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and to provide a kind of and to optimize production technology in order reducing cost, and enhances productivity, and satisfies the electrothermal tube assembly of the band novel flange structure of production demand.
The purpose of this utility model is finished by following technical solution; comprise stainless steel electrical heating tube element and steel flange; the cylindrical lateral surface of described steel flange is provided with boss structure; the boss structure place is placed with the sealing ring for sealing, and this steel flange and stainless steel electrical heating tube element are fixing with the welding of nickel soldering paste scolder by atmosphere protection.
As preferably, described steel flange adopts stainless steel materials punching press, drawing and forming.
The beneficial effects of the utility model are: new flange arrangement adopts the stainless steel materials punching press, and drawing and forming is easy to moulding, and technical maturity is reliable; The boss design of new flange arrangement can be satisfied the hermetically-sealed construction dimension precision requirement of conventional brass flange equally, does not influence sealing property; Steel flange and stainless steel electrical heating tube element all adopt stainless steel material, and welding performance improves greatly; Be applicable to that conventional soldering oven welds in enormous quantities, raise the efficiency, save cost; The weld sealing property is superior, and surface clean is smooth, is difficult for getting rusty.
