Abstract
The utility model relates to the technical field of pressure vessel, in particular to an ellipse pressure vessel end enclosure. The utility model discloses an ellipse pressure vessel end enclosure, the upper part of the end enclosure is in a semiellipse shape, and the lower part of the end enclosure is provided with a circle of straight flange surrounding the ellipse opening. The utility model adopts the semielliptic upper part, so the longitudinal section of the half-elliptic upper part is a semiellipse curve. The radius of curvature of the curve continually changes without abrupt shape change positions, so the stress distribution of the end enclosure is more uniform, and the stress condition of the end enclosure is more advantageous than that of a dished end enclosure. In the utility model, the lower part adopted the end enclosure is provided with a circle of straight flange surrounding the ellipse opening so as to prevent the overlap of heat stress and edge stress.
Description
Technical field
The utility model relates to the pressure vessel technology field, relates in particular to a kind of oval pressure vessel head.
Background technique
End socket is the main pressure-containing member of pressurized container.It forms a complete seal container as the closed end of container with cylindrical body.Traditionally, end socket usually is meant with cylindrical body and is welded to connect into on-disconnectable container end portion structure; And with cylindrical shell by the removable structure that bolt orchid etc. is connected, then be referred to as end cap.Under pressure, the size of the stress on the end socket shell wall is all relevant with its pattern, shape with distribution.The pattern of right selection end socket and dimensional parameters, also be in the design of pressure vessels with a security-related problem.So it is vital how finding a not only safe but also practical end socket.
Summary of the invention
The utility model provides a kind of and can reach usage requirement in order to solve the defective that above-mentioned end socket exists, and can save the oval pressure vessel head of material again.
Its concrete technological scheme is: a kind of oval pressure vessel head, the top of described end socket are half elliptic, and the bottom of described end socket is with a circle straight flange around oval mouth.
Wherein optimal way does, the material of described end socket is iron or stainless steel or aluminium.
The employing of the utility model top be half elliptic, its longitudinal section is a bar semiellipse curve.The radius of curvature of curve changes continuously, does not have shape sudden change place.Thereby the stress distribution of end socket is more well-balanced, and force-bearing situation is more superior than dished (torispherical) head.The employing of the utility model to be with a circle straight flange around oval mouth be in order to prevent the stack of thermal stress and edge stress the bottom of end socket.
Description of drawings
Fig. 1 is the schematic representation of the utility model.
Embodiment
