Title:
SPRINKLER EQUIPMENT FOR SMALL-SCALE BUILDING SUCH AS RESIDENCE
Document Type and Number:
Japanese Patent JP3941004
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide sprinkler equipment which is low-cost equipment and never requires a fire pump, a fire water tank and an emergency power generator and which is capable of primary extinguishment even when power is interrupted as for the sprinkler equipment for a small-scale building such as a residence.
SOLUTION: By storing fire extinguishing liquid in a fire extinguishing liquid pipe, the fire extinguishing liquid pipe can be shared by a plurality of buildings. By using compressed air or inert gas as a water feeding pressure source for the operation of the fire extinguishing liquid pipe, operation is possible even when running water and power are interrupted. Then, the fire extinguishing liquid pipe is not pressurized in a normal state. When coming to fire extinguishing operation in the occurrence of a fire, the compressed air or inert gas is pressurized to the fire extinguishing liquid pipe shared by the plurality of the buildings, but the fire extinguishing liquid is discharged only from the sprinkler head of the building where the fire occurs, thereby safety is kept. When the fire extinguishing liquid in the fire extinguishing liquid pipe runs out, the compressed air or inert gas is released to the atmosphere through an automatic gas release valve without being discharged indoor, thereby safety is kept.
