DEVICE FOR PRESSURE-TIGHT CONNECTION OF MOVABLE PIPING MEMBERS Russian patent published in 2007 - IPC F16J15/52 

FIELD: piping engineering.

SUBSTANCE: device comprises rubber-cord shell whose sides are interposed between the corresponding bearing and adjusting end members. The bearing ring members are provided with openings for receiving the threaded members used for fastening the bearing ring member to the corresponding movable member and provided with the sealing member that cooperates with the bearing area of the movable member in operation. The rubber-cord shell and bearing and adjusting ring members are made so that they form a single nondetachable unit in which the adjacent bearing and adjusting ring members are interconnected by means of weld. The sides of the rubber-cord shell are interposed between the bearing and adjusting ring members with preliminary pressing with a given load.
