Safety device for containers of explosive, and explosive containers method of preparing safe for explosives containers.

摘要

A device (4) safety containers (8) of explosive substances, said containers (8) a chamber (12) housing hydraulically sealed for an explosive substance delimited by at least one closing wall 16 comprising, said wall (16 ) closing an opening (20) purge; the device (4) comprising at least one structure (28) suitable closure to seal said opening (20) purge, - comprising mechanically separated structure means retaining device (34, 38, 42) (28) closure and suitable to strengthen the structure (28) closing the opening (20) purge, wherein said means (34, 38, 42) comprise: - an element (38) melting, suitable to melt in order to release the structure (28) closing in case a threshold predetermined temperature is exceeded below the temperature conditioning of explosive, said element (38) melting in an assembled configuration interferes being at least partially structure (28) closing to prevent removal of the structure (28) for closing the chamber (12) containment, characterized in that the means (34, 38, 42) retaining further comprises an element (42) splicing In an assembled configuration interferes with the element (38) fusion to block the element (38) melting in a position against the structure (28) closing, in which said element (38) melting, in an assembled, setting is previously introduced in compression between the element (42) and splice structure (28) closing in the opening (20) purge has an axial symmetrical shape relative to an axis (XX) and structure (28) closure has a corresponding externally to the inner shape of said opening (20) of purging, in which the element (38) melting has an annular shape, so that in an assembled configuration is axially symmetrical about the axis (XX) of the opening (20), in that the element (38) melting, in an assembled configuration, is previously introduced in compression between the element (42) and splice structure (28) closing, according axial direction parallel to said axis (XX) of the openings, to (20).
