Abstract
A valve assembly for a pressure vessel is disclosed that includes a valve housing operatively associated with an outlet of the pressure vessel, a frangible hermetic disc sealing the outlet of the pressure vessel, and a poppet valve mounted for movement within the valve housing between a first position supporting the frangible hermetic disc within the outlet of the pressure vessel and a second position spaced apart from the frangible hermetic disc to permit the frangible disc to burst under pressure and permit the egress of pressurized material from the pressure vessel through the outlet.
Claims15
A valve assembly for a pressure vessel, comprising:
- a) a valve housing operatively associated with an outlet of the pressure vessel;
- b) a frangible disc sealing the outlet of the pressure vessel;
- c) a poppet valve mounted for movement within the valve housing between a first position supporting the frangible disc within the outlet of the pressure vessel and a second position spaced apart from the frangible disc to permit the frangible disc to burst under pressure and permit the egress of pressurized material from the pressure vessel through the outlet.
A valve assembly for a pressure vessel, comprising:
- a) a frangible disc hermetically sealing an opening of the pressure vessel and configured to rupture under pressure;
- and
- b) a valve member mounted for movement between a locked position in which a contact surface of the valve member supports the frangible disc within the opening of the pressure vessel to prevent the disc from rupturing and an unlocked position in which the contact surface of the valve member is spaced apart from the frangible disc to permit the frangible disc to rupture under pressure and permit the egress of pressurized material from the pressure vessel through the opening.
