DEVICE FOR PRESSURISING A SOCKET

摘要

The invention relates to high-pressure vessels, more specifically to a device for pressurising a socket with the aid of an internal hermetic envelope arranged in the neck of said vessel. The inventive device for pressurising the socket comprises a flange arranged on the socket, the disk thereof being encompassed by a power casing of a body, a barrel accommodated in the axial orifices of the socket and the flange in such a way that they form a circular cavity containing a compactor, a ring and a unit for fixing the barrel arranged therein. Said device is provided with a retaining ring with a cant. Flat elements forming ribs and a groove are embodied on the external surface of the barrel on the open side thereof. The retaining ring is partially arranged in the groove in such a way that the cant thereof is oriented towards the flange. The fixing unit which is formed by a circular coil encompassing the flat elements, the retaining ring and the remaining part of the flange form a bloc together with the power casing of a body.
