Title:
FIRE EXTINGUISHING EQUIPMENT
Document Type and Number:
Japanese Patent JP3918967
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To cope with a type fire and B type fire by providing a fire extinguishing head a deflector exposed to the outside on a secondary side piping of a mixer connected to a water supply source and an aqueous film bubble extinguishing chemical agent source.
SOLUTION: A mixer 6 is connected to a water tank 2 storing fire extinguishing water W and a chemical tank 4 storing an aqueous film bubble fire extinguishing chemical agent G. A closed type fire extinguishing head 8 is connected to the secondary side pipe of the mixer 6 and disposed in a protection area having the possibility that both A type fire and B type fire occur. The closed type fire extinguishing head 8 has a flat deflector having no claw in the peripheral edge part exposed, thereby dispersing bubble water solution as substantial water solution in the protection area. The deflector is covered with a wire netting to heighten the foaming magnification of discharged bubble water solution. Thus, both the A type fire and B type fire can be extinguished effectively.
