Further, the cover plate is fixed with an annular gland through bolts, and the gland and the cover plate clamp and fix the O-shaped ring.
Further, the gland consists of a left part and a right part.
Further, a lifting lug is fixed on the surface of the cover plate in the center of the O-shaped ring.
Further, an annular cylinder flange is fixed at the opening of the container cylinder, and the upper flange is fixedly connected with the upper flange through bolts and nuts penetrating through the cylinder flange and the upper flange.
Further, the angle of the bevel of the opening of the upper flange is equal to the angle of the chamfer of the cover plate.
Further, a semicircular groove is formed in the chamfering position of the cover plate.
Further, an annular positioning boss is arranged on the outer edge of the upper end face of the cover plate.
Further, the O-shaped ring is clamped in a semicircular groove formed by the gland and the cover plate, and the outer edge of the O-shaped ring is positioned outside the gland.
Through the arrangement, the sealing structure adopts the sealing structure that the inclined plane bumps the inclined plane, and the O-shaped ring is embedded on the inclined plane to form the sealing layer, so that the effect of pressing and sealing can be achieved through the self-centering principle of the conical surface. The gland for fixing the O-shaped ring is divided into two parts, so that the O-shaped ring can be replaced conveniently and quickly. The sealing structure of the utility model is more stable and firm, can be used for a long time, is not easy to deform, and is particularly suitable for pressure vessels needing frequent and rapid door opening and closing.

Detailed Description
As shown in fig. 1-3, a sealing structure for quick door opening of a pressure container comprises a cover plate 4 and an upper flange 3, wherein one end of an opening of the upper flange 3 is an inclined plane, an O-shaped ring 8 fixed on one surface of the cover plate 4 contacts with the inclined plane of the opening of the upper flange 3 to realize sealing, the cover plate 4 is fixed with an annular gland 5 through a bolt 6, the gland 5 consists of a left part and a right part, the gland 5 and the cover plate 4 clamp and fix the O-shaped ring 8, the O-shaped ring 8 is clamped in a semicircular groove formed by the gland 5 and the cover plate 4, and the outer edge of the O-shaped ring 8 is positioned outside the gland 5.
The apron 4 fixed surface at O type circle 8 center has lug 7, and the position of the chamfer of apron 4 is provided with the semicircle groove, and the up end outer edge of apron 4 is provided with annular location boss, and the opening of container barrel 1 is fixed with annular barrel flange 2, goes up flange 3 through running through barrel flange 2 and the bolt nut 9 and barrel flange 2 fixed connection of flange 3, and the angle of the chamfer of upper flange 3 opening inclined plane equals with the angle of the chamfer of apron 4.
The working principle of the utility model is as follows: the sealing structure adopts a sealing structure that the inclined plane bumps the inclined plane, and the sealing layer is formed by embedding the O-shaped ring on the inclined plane, so that the effect of compressing and sealing can be achieved by the self-centering principle of the conical surface. In order to facilitate replacement of the O-shaped ring, the sealing structure cuts the O-shaped ring gland into two parts, so that the purpose of quickly replacing the O-shaped ring is achieved.
The foregoing is illustrative of the present utility model and is not to be construed as limiting the scope of the utility model. Any equivalent changes and modifications can be made by those skilled in the art without departing from the spirit and principles of this utility model, and are intended to be within the scope of this utility model.
