Liquefied gas tank safety device comprises a pressure-triggered safety mechanism that sprinkles the pressure tank walls with the liquid gas phase to provide a cooling mechanism if the tank is exposed to fire or heat

摘要

The safety device for a pressurized tank for containment of liquefied gases comprises a pressure-triggered cooling device (12), which when triggered sprays the wall (32) of the tank (10) with the liquid phase (18) of the gas. The invention also relates to a pressurized tank for containment of gas liquefied under pressure that incorporates an inventive safety device.
