Abstract

PURPOSE:To secure such a pressure vessel that is lighter in weight and inexpensive in cost in an easy manner by welding a disklike end plate of the same size as the outer diameter, to both ends of a cylindrical vessel, and also welding a reinforcing material radially formed plural pieces of ribs being connected to an inner circumferential surface from a center axis in the same diametral cylinder. CONSTITUTION:A cylindrical vessel 1 being composed of an Al alloy in all is covered of both the ends with a dislike end plate 2 of the same outer diameter as the barrel vessel 1, and both these elements are joined together by means of welding. In this case, since axial pressure in the vessel 1 is entirely added to the end plate 2, reinforcement is required to make the end plate 2 resistible to the pressure. The reinforcing material 3 is a cylinder of the same outer diameter as the end plate 2, and the cross section is one that is made up of forming plural pieces of ribs 3a being connected to an inner circumferential surface from a center axis radially in the axial direction, and this reinforcing material 3 is welded to the side of the end plate 2, the length varies according to pressure to be added to the end plate 2. In this connection, since the Al alloy is very excellent in extrusibility as compared with a soft steel plate, a suchlike reinforcing material 3 is easily securable by means of extruded section.

た。(Problems to be Solved by the Invention) Magnetic levitation trains using linear motors are currently being put into practical use. Therefore, in order to reduce the weight of vehicles, development of vehicle bodies and other on-vehicle equipment using N alloys is underway. For example, N-alloy pressure vessels are being considered for storage tanks for liquid helium, liquid nitrogen, etc. that are mounted on trolleys, but N-alloy is difficult to process, so the dish-shaped end plates welded to both ends of the cylinder are made of AJ2 alloy. When manufacturing, there was a problem in that the mold was expensive and the cost was high.

充分支えることができる。(Function) With the end plate reinforcement constructed as described above, pressure in the axial direction of the cylindrical container is applied perpendicularly to the disc-shaped end plate due to the pressure inside the tank, but this pressure is sufficiently absorbed by the ribs of the reinforcing material. It can be supported.
