    • The present invention features a fire safety apparatus for a high-pressure gas fuel tank of a vehicle, comprising a pressure relief device that is disposed between a tank connection channel and an outside connection channel in a tank valve of a high-pressure fuel tank and that connects the tank connection channel with the outside connection channel when the tank valve increases in temperature over a predetermined level in a fire, and a suitable intumescent that is hydrate disposed with the high-pressure fuel tank to increase in volume and absorbs heat, with the water from evaporation in a fire, and delay the flames spreading over the high-pressure fuel tank by producing a heat insulation barrier after the water evaporates.According to preferred embodiments of the present invention, it is possible to prevent a high-pressure fuel tank from exploding due to a fire and to preclude secondary damage due to the high-pressure fuel tank, by delaying the flames spreading over the high-pressure fuel tank with a suitable intumescent that prevents the high-pressure fuel tank from being damaged and exploded by the flames, preferably before a pressure relief device operates in a vehicle on fire.
    • 本发明的特征在于一种用于车辆的高压气体燃料箱的消防安全装置,包括一个压力释放装置,该压力释放装置设置在高压燃料箱的罐阀中的罐连接通道和外部连接通道之间, 当罐阀在火灾中在预定水平温度上升时,将罐连接通道与外部连接通道连接,并且与高压燃料箱水合物配合以增加体积并吸收热量的合适的膨胀剂与 在火中蒸发的水,并且在水蒸发后通过产生隔热屏障来延迟火焰蔓延在高压燃料箱上。 根据本发明的优选实施例,可以防止高压燃料箱由于火灾而爆炸,并且防止由于高压燃料箱引起的二次损坏,通过延迟火焰在高压 具有合适膨胀的燃料箱,其防止高压燃料箱被火焰损坏和爆炸,优选地在减压装置在车辆起火之前操作。
