Abstract:
1. An automatic fire extinguishing system using liquefied CO 2 to regulate the distribution of fire extinguishing agents, said system consisting of the following equipment: an ordinary water tank for fire extinguishing; containers providing sufficient liquefied CO a scale or device for automatically checking the weight of CO an automatic pressure adjusting device; a reversing device closing the valve to supply CO a reversing device open/closing the valve to supply the fire extinguishing agent from the high pressure tank to a distribution system; a device for receiving signals from the fire alarm system, automatically opening the valve supplying the fire extinguishing agent from the distribution to an alarm bell and to a power switch-off device of the object to be protected, and then to a fire extinguishing drencher; two high pressure tanks placed at positions favorable for receiving a naturally returning fire extinguishing agent with level indicating float valves at the bottom, wherein when the fire extinguishing agent is running out, the float is lowered opening the valve connecting to the CO a fire alarm self-breaking sprinkler which discharges pressure when the temperature increases to the required level; the fire alarm bell or water bell which starts for people to evacuate when the fire extinguishing agent is sprayed; the device using pressure to switch off power for the object to be protected so as to ensure safety during the fire extinguishing process; a pipeline and an automatic valve supplying CO a safety valve and a pressure meter for the high pressure tanks, specialized high pressure drenchers for spraying water mist when water is needed to put out fires caused by petrol or oil; self-sucking injectors to supplement foaming agent with a suitable ratio added to water to put out fires caused by petrol or oil, using the flow of water circulating in the pipe as sucking dynamics; a device using pressure to reverse the closing gate of the ordinary water waste system and opening gate to allow the fire extinguishing agent to return to the settling, filtering and oil separating system; a system for settling, filtering, oil separating and the system for regulating and distributing the reserved water to fill up the receiving container promptly; valves, pipe, hose, the fire extinguishing equipment installed in the walls; all the high pressure devices being interconnected by pressure sustainable pipe and provided with enough pressure by CO the liquefied CO
