SEALING ASSEMBLY OF REFUELING MACHINE JUNCTION PIPE FOR PRESSURIZED-TUBE REACTOR Russian patent published in 2005 - IPC

Abstract RU 2248633 C1

FIELD: sealing engineering; refueling machines for pressurized-tube reactors.

SUBSTANCE: proposed sealing assembly has sealing facility in the form of W-shaped stacks with arched cavities and casing-mounted junction pipe installed between two supporting rings. Flexible sealing member rests on upper supporting ring. Flexible separating members are disposed between W-shaped stacks. Flexible member is installed above flexible sealing member for actuating the latter. Each separating member is made in the form of flexible ring having three cross bends in its sectional area of which top one is arranged in a spaced relation above top of W-shaped stack. Two bottom ones are disposed in arched cavities of W-shaped stack and contact its blades at points disposed not above top of W-shaped stack.

EFFECT: enhanced reliability of sealing assembly.
