Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
In the description of the present invention, it is to be understood that the terms "center", "lateral", "up", "down", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention. "plurality" means two or more unless otherwise specified.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected. Can also be detachably connected or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases for those skilled in the art.
Example one
As shown in fig. 1 and 2, the water heater liner comprises a cylinder body 1 and end covers 2 on two sides, wherein the cylinder body is connected with the end covers in a welding mode, the welding ports of the cylinder body and the end covers are flared to form slope walls 3, the cylinder body and the end covers are welded in a butt-collision mode, a circumferential weld 4 with a triangular cross section is formed between the adjacent slope walls, and black coating blocks in the drawing represent filling welding in the circumferential weld 4.
Before welding, the welding ports are preprocessed, and flaring and slope rising are carried out on the ports on the two sides to be welded of the barrel body to manufacture a welding joint with a slope. Because the plates of the cylinder body and the end cover have certain thickness, when the welding port is inclined, the side wall of the plate of the port forms an inclined plane a and a plane b, the two welding ports of the end cover and the cylinder body are close to form an angular ring groove with an opening at the upper end and a butting at the lower end, and then the welding wire is adopted to weld on the circular welding seam with a triangular section. The inclined angle of the slope wall inclined towards the central shaft is C, so that a groove for welding is formed at the joint of the two openings, and the welding quality is improved.
When welding metals, inert gas is used to protect the weld metal in order to prevent the weld metal from oxidizing. When the inert gas is used for protecting the weld metal, the front surface of the weld metal can be protected when the inert gas is introduced due to the self-contained nozzle of the welding gun. In order to prevent the back of the welding line from being oxidized, back inert protective gas can be added on the back of the welding line (namely the inner cavity of the liner to protect the back, so that the qualified welding line is obtained.
As shown in figure 2, the welding joint of the cylinder body is formed into a slope inclined plane by directly flaring and pressing the opening part, the inclination angle of the slope wall is C, the slope wall enables the welding alignment to be simpler and faster, the alignment is more orderly, and the welding difficulty is greatly reduced. The circumferential weld ensures the penetration, similarly increases the bone structure and enhances the rigidity. By adopting the girth welding method, the welding quality of the welding seam is high, the pressure-bearing capacity is strong, and the water leakage of the welding seam can be effectively prevented. The welding process of the inner container is finished at one step, the phenomena of welding failure, overlarge back welding beading and the like are overcome, and the production automation degree is greatly improved.
The end caps are arcuate. The wall thicknesses of the plate of the cylinder body and the plate of the end cover are the same, the slope wall slopes of the cylinder body and the slope wall of the end cover are the same, and the cross section of the circumferential weld is in an isosceles triangle shape. The welding quality of the welding seam is high, the bearing capacity is strong, and the water leakage of the welding seam can be effectively prevented.
Example two
The embodiment improves the cylinder structure on the basis of the first embodiment. As shown in fig. 3, a plurality of reinforcing ring ribs 5 are provided on the wall of the cylinder 1 to form a wave-shaped wall structure. The barrel of inner bag is along the axial to be corrugate, and the diameter of the ascending cross section of inner bag edgewise has the difference, has certain reinforcing effect to the intensity of inner bag, and wave groove moderate in interval can be used for increasing structural strength and absorbing certain thermal energy, and when having effectively reduced the inner bag pressurized, the injury of shear stress butt weld makes the inner bag more reliable, welded structure more stabilizes the life that has improved the inner bag greatly.
EXAMPLE III
The water heater inner bag conventional structure form is about two end covers add a stack shell welding and forms, and two parallel girth welds of a transversal joint welding on the inner bag, and this embodiment provides the structural style of another kind of inner bag, sets up left and right end cover as an organic whole with left and right half barrel respectively, then butt joint welding, only a girth weld, the welding is firm, and welding quality is good. As shown in figure 4, the water heater liner is formed by welding two open end enclosures 6, wherein the two end enclosures 6 are both formed by stretching metal materials and comprise a cylinder body and an arc-shaped bottom wall which are integrally formed by stretching. Flaring openings of the two end enclosures to form slope walls 3, butting the openings of the two end enclosures, and forming a circumferential weld 4 with a triangular section between the adjacent slope walls.
In order to improve the strength of the liner, a plurality of reinforcing ring ribs are arranged on the wall of the cylinder body to form a wave-shaped wall structure (not shown in fig. 4), and the specific structure refers to the cylinder wall structure of the second embodiment.
While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents, and all changes that can be made without inventive step are intended to be embraced therein.
