に噴射させることができない。 Therefore, even if a person discovers the fire at an early stage, the fire cannot be extinguished until the fuse metal of the sprinkler head is melted and the sprinkler head is released, and during that time the fire is left to burn. In addition, there is a risk that one of the multiple outdoor storage tanks located nearby could catch fire if it were located upwind, and the sparks from the fire could fall on the floating roofs of other outdoor storage tanks located downwind, causing a subsequent fire. Even if such a dangerous situation occurs, it is not possible to arbitrarily inject halon-based fire extinguishing agent onto the floating roof in order to prevent it from occurring.

なうのである。 That is, when an initial fire occurs around the floating roof and the fuse metal of the sensing head in that area melts, gas leaks from the released sensing head and the gas pressure in the annular conduit decreases. The differential pressure communication chamber of each pressurized release valve is connected to a branch pipe of each connecting pipe while suppressing the influence on each halon pressurized storage tank, which is connected to a plurality of connecting pipes via orifice valves. pressure decreases,
As a result, the pressure in each differential pressure communication chamber becomes smaller than the gas pressure on the side of each inlet of each pressurized release valve, and the piston body is moved into the differential pressure communication chamber by the pressure on the side of the inlet. The closing disc connected to the piston body is pulled away from the through hole in the partition wall, and the inlet and outlet are connected to each other through the opened through hole. The halon-based extinguishing agent is communicated from the inlet of each pressurized release valve to the conduction pipe connected to the extinguishing agent outlet of each halon pressurized storage tank, passes through the outlet, and passes through the delivery pipe. enters each divided conduit, and is injected all at once from a large number of halon heads (open type) installed in each divided conduit, automatically extinguishing the fire with halon-based extinguishing agent.

のである。 If an initial fire occurs around the floating roof under the above conditions, the fuse metal of the sensing head will be melted by the heat of the fire and gas will leak from the sensing head, resulting in a drop in gas pressure. Therefore, the piston body in the differential pressure communication chamber of the pressurized release valve is activated, and the closing disc is separated from the valve seat opening of the through hole in the partition wall, and the inlet and outlet are communicated automatically. However, in the present invention, the pressure sensing device installed outside the outdoor storage tank is activated at a point earlier than the fuse metal of the sensing head melts, or regardless of the fire. By opening the on-off valve of the gas cylinder attached to the on-off valve, non-flammable high-pressure gas is introduced into the pressure introduction chamber of the pressurized release valve that communicates with the branch pipe of the common conduit connected to the communication pipeline connected to the on-off valve. Immediately sends the valve through the valve to activate the activation body with upper pressure, pushes up the closing disc with a rod, breaks the sealing plate, and quickly separates the closing disc from the valve seat opening of the through hole in the partition wall.
The inlet port and the outlet port are connected to each other, and the halon-based extinguishing agent from the extinguishant discharge port of the halon pressurized storage tank connected to the inlet port is fed under pressure to the divided conduit connected to the outlet port. Halon extinguishing agent can be emitted all at once from the multiple halon heads of the divided pipes.

のである。 That is, in the present invention, by opening the on-off valve of the gas cylinder attached to the pressure detection device installed outside the outdoor storage tank at any time as described above, the halon-based extinguishing agent can be forcibly applied all at once. Since the fire can be emitted, it is possible to detect the beginning of a fire and quickly extinguish it without waiting for the detection head to automatically extinguish the fire. In the event that another outdoor storage tank or other structure that has been installed catches fire and there is a dangerous situation in which sparks fall, etc., a halon-based extinguishing agent is forcibly emitted at any time to protect the tank and prevent further fires. This has the effect of making it avoidable.
