Abstract:
A localized fire protection system for composite overwrapped pressure vessels which uses net or mesh which stretches in at least one direction. They can be elastomeric or polymeric or any material and/or weave that provides said function. Wrapping sections held together via a flammable fuse connected to a relief valve under pressure from the net wrappings to block a relief valve pathway to replace stored gas in case of a localized fire.

Claim (Index 1):
A fire activatable pressure relief method for pressurized gaseous fuel tanks, the method comprising:\n surrounding a pressurized gaseous fuel tank or vessel ( 10 ) having a fluid connection into the tank and a valve ( 40 ) at its distal end ( 14 ) end with a plurality of stretchable net coverings ( 22 A- 22 F); anchoring the first covering ( 22 A) to one end ( 12 ) of the tank; affixing the additional net coverings ( 22 B- 22 F) to the first covering forming a mesh ( 20 ) via one or more fire and temperature sensitive fuse wire ( 30 ); affixing the net covering at the distal end ( 14 ) of the pressure vessel to an actuator ring ( 37 ); connecting the actuator ring to a thermally-activated pressure relief device \u201cTPRD\u201d system ( 50 ) to compress a spring ( 206 ); and, a movable spool ( 200 ) associated with the spring moves within the TPRD system to block the fluid path ( 300 ) of stored gas through the TPRD to the atmosphere unless the fuse is exposed to a temperature beyond a threshold level.
