A temperature-sensitive glass ball is installed on the nozzle of the spray header of mounted stored pressure dry power fire-fighting equipment, and in normal conditions, the upper end of the glass ball bears against the sealing strip on the nozzle. When there’s a fire, the temperature goes up, liquid in the glass ball automatically breaks because of expansion by heat, the sealing strip automatically falls off and dry power agent in the fire-fighting equipment with nitrogen’s drive sprays from the nozzle to extinguish fire. This series of fire-fighting equipments can extinguish fire quickly and can be used safely, and toxicity of the extinguishing medium is low.
