Sealing System for High-Pressure and Temperature Containers

摘要

A sealing system for a container ( 2 ) containing a fluid at high pressure, comprising a head ( 10 ) moving between a closed position and an open position of the container ( 2 ), a piston ( 12 ) for the pressurisation of the container ( 2 ) mounted to slide within the head ( 10 ) and sealing means adapted to prevent fluid from emerging from the pressurised container ( 2 ). These sealing means comprise an auxiliary cover ( 22 ) adapted to be interposed between the head ( 10 ) and the container ( 2 ), provided with an opening ( 24 ) in which the piston ( 12 ) may slide and a coinable gasket ( 28 ) associated with the opening ( 24 ) adapted after its coining to exert a sliding seal between the piston ( 12 ) and the cover ( 22 ).
