FIRE EXTINGUISHING EQUIPMENT

Japanese Patent JP3963221

B2

PROBLEM TO BE SOLVED: To provide fire extinguishing equipment which has water in piping normally, and in case of fire, supplies a foaming water solution to an extinguishing head and discharges the solution, and the equipment which can prevent the spread of the fire until the foaming water solution replaces the water in the piping by increasing the amount of the sprayed water from the extinguishing head.
SOLUTION: Water spraying density indicates the amount of discharged water (L) per unit time (min) and per unit area (m2). Designed water spraying density of a closed type spraying head H is set to 7-12 (L/min×m2). Normally, the piping which connects to the closed type spraying head H is filled with water, and in case of fire, the foaming water solution is supplied. In the fire extinguishing equipment which has the water in the piping normally, and in case of the fire, supplies the foaming water solution to the closed type spraying head and discharges the solution, the water spraying density of one closed type spraying head is set to 7-12 L/(min×m2). Therefore, the fire extinguishing equipment can prevent the spread of the fire until the foaming water solution replaces the water in the piping.
