摘要： PROBLEM TO BE SOLVED: To provide a hot water storage tank capable of attaining a long life of a tank main body.SOLUTION: A supporting device 2 (Fig.1(b)) is fixed to a lower end plate 11 of a tank main body 1 storing hot water and receiving inner pressure, through a fixing member 20 (Fig.1(a)). Although a plate-like part 21 of the fixing member 20 is welded to the lower end plate 11 by spot welding, the lower end plate 11 is extended or shrunk by pressure variation generated at the tank main body 1 and a high stress is generated at a welded part 28, in particular, the welded part 28 of a lower side member 21c. Then, the side member 21c is provided with a recess part 21s acting as a low rigidity part recessed in the direction of the axis the lower end plate 11. With this arrangement, since the welded part 28 of the side member 21c can be easily deformed following a deformation of the lower end plate 11, stress at the welded part 28 is released and its fatigue breakdown can be prevented and a long life of the tank main body 1 can be attained.

摘要： PROBLEM TO BE SOLVED: To provide a brazing joint structure, and a joining method for metal piping capable of maintaining a necessary brazing clearance even when brazing two pipe materials with a difference in linear expansion coefficients.SOLUTION: In a joint part 6 constituted by inserting a reduced part 2 of inscribed side piping 1 into an expanded part 4 of circumscribed side piping 3 having a vertical groove 5 on an inner face, the circumscribed side piping 3 and the inscribed side piping 1 are brazed together. If a linear expansion coefficient of the circumscribed side piping 3 is larger than a linear expansion coefficient of the inscribed side piping 1, the expanded part 4 is expanded more than the reduced part 2 by heating during joining, and the joint part 6 is deformed in a separating direction of an reduced part 2 outer face and an expanded part 4 inner face. Even in such a case, by the brazing joint structure, the reduced part 2 is inserted deeper into the expanded part 4 inner face by self-weight of the inscribed side piping 1 and a pressure by a pressurizing mechanism, and the expanded part 4 inner face and the reduced part 2 outer face are closely adhered again. By this, a depth of the vertical groove 5 of a closely adhered portion becomes the brazing clearance, a stable brazing flow can be achieved, and highly reliable brazing can be carried out.
摘要翻译：要解决的问题：为了提供钎焊接头结构，以及即使当钎焊具有线膨胀系数差的两种管材时，也能够保持必要的钎焊间隙的金属配管的接合方法。解决方案：在通过将内接侧管1的减少部分2插入内表面具有垂直槽5的外接侧管3的膨胀部分4中构成的接头部分6中，外接侧管3和内刻侧管1钎焊在一起。如果外接侧管3的线膨胀系数大于内接侧管1的线膨胀系数，则膨胀部4在接合时通过加热而比缩径部2扩大，接合部6变形缩小部分2外表面和扩展部分4内表面的分离方向。即使在这种情况下，通过钎焊接头结构，通过内接侧管道1的自重和加压机构的压力将还原部分2更深地插入到膨胀部分4的内表面中，并且膨胀部分4内部面部和缩小部分2的外表面再次紧密粘合。由此，紧贴部分的垂直槽5的深度变为钎焊间隙，可以实现稳定的钎焊流动，并且可以进行高可靠性的钎焊。版权所有（C）2012，JPO＆INPIT
