HIGH PRESSURE VESSEL FOR HIGH PRESSURE PRESS Russian patent published in 2013 - IPC F17C1/00 B30B11/00 

FIELD: machine building.

SUBSTANCE: high pressure vessel includes at least the first sub-cylinder and the second sub-cylinder, which are coaxially connected so that formation of a cylindrical housing for high pressure medium is possible, and a sealing structure arranged on inner wall of the cylindrical housing for sealing of the connection between the first and the second sub-cylinders against high pressure medium leakage. The sealing structure includes a ring-shaped sealing strip, the first projecting flange that is arranged on inner wall of the first sub-cylinder and that is coaxially continued from the connection and to the side from the second sub-cylinder, and the second peripherally projecting flange. The flange is arranged on inner wall of the second sub-cylinder and that is axially continued from the connection and then from the first sub-cylinder. The sealing strip when in the installed position is arranged concentrically within the limits of the first and the second projecting flanges so that it tightly adjoins the first and the second projecting flanges by means of radial pre-stress and covers the connection between the first and the second sub-cylinders so that tightness is ensured. Besides, the sealing structure includes the first peripheral installation space that is arranged on inner wall of the first sub-cylinder and that is axially continued from the first projecting flange and then from the second sub-cylinder to provide the replacement of components of the sealing structure. Method applied for replacement of worn-out sealing strip of high pressure vessel is described.

EFFECT: higher reliability of the device.
