Abrégé

The invention relates to a closure for ducts or receptacles for pressurized fluids, comprising a fixed part (10), to be applied at an end of a tubular element (100), said fixed part comprising an opening (12) communicating with the duct or receptacle, a moving part (30), rotatably connected to said fixed part, movable between a closed position and an open position and a sealing element (40) to be placed in the opening of the fixed part; wherein said moving part, in the closed position, blocks said sealing element in the opening, wherein said fixed part, at the opening, comprises a sealing surface (14) produced on the inner surface of a cylindrical surface that extends from the opening toward the tubular element, and wherein said sealing element comprises a body in the shape of disc or cylinder adapted to coact with said sealing surface to guarantee the hermetic seal of the closure.

Abrégé

Disclosed is a closure for ducts or receptacles for pressurized fluids, including an annular supporting structure (10), which defines an opening (11) for accessing the duct or receptacle, and a hatch (30), connected in an articulated manner to the supporting structure (10), with the ability to move between a closed position and an open position, wherein the supporting structure (10) includes a sealing surface (13), characterized in that it includes a sealing element (20) that can be positioned in the opening (11), the sealing element (20) including an expansible portion (21) with an inner surface (24) facing the duct and an outer surface (23) facing the sealing surface (13), the expansible portion (21) being able to expand as a result of the pressure of the fluid that acts on the inner surface (24) so that the outer surface (24) is placed in contact with the sealing surface (13).
