DEVICE FOR AUTOMATICALLY EXTINGUISHING FIRE FOR BUILDING

摘要

PURPOSE: An automatic fire extinguisher for a building is provided to initially extinguish fire by quickly discharging extinguishing powder. CONSTITUTION: In generating fire, a controller controls an alarming bell and a guide broadcasting by receiving a fire detecting signal of a fire detecting sensor. The controller operates a solenoid to open a CO2 tank. A needle valve (12) opens an extinguishing powder opening/closing valve (12) and a N2 tank by CO2 gas. Extinguishing powder (19) is quickly discharged by pressurizing force of the N2 gas (20). The nitrogen gas through a N2 tank is inserted into an extinguishing powder tank (5) through a flexible hose (14) to pressurize the extinguishing powder (19). Thereby, the extinguishing powder (19) is discharged quickly.
