Problems solved by technology

[0005] Disadvantages of using thermoelastics are on the one hand the high acquisition costs and on the other hand the poor fire resistance of these materials
In the event of a fire, it may happen that the pipes melt due to the great heat of the fire, so that a good fire fighting effect can no longer be achieved

Embodiment Construction

[0024] figure 1 A fire extinguishing device 1 is shown, which comprises a closure device 2 and a pressure bottle 6 . The closure device 2 is composed of an adapter part 8 , a connection part 12 , a standpipe 14 and a rupture disc 18 a. A submerged tube 10 inclined toward the inner wall of the pressure bottle 6 is provided inside the pressure bottle 6 . This submerged pipe 10 is located below the level of the extinguishing liquid 4 . In case of fire, compressed air is introduced into the pressure bottle 6 through the compressed air applying device 22 provided with a one-way check valve (not shown), and the fire extinguishing liquid is sprayed out from the pressure bottle 6 .

[0025] The closure device 2 is formed in such a way that the standpipe 14 bends, preferably perpendicularly, from the connecting piece 12 into the vertical. The rupture disc 18 a is arranged in the standpipe 14 such that the rupture disc is above the level 16 of the extinguishing liquid 14 . A gas spa...

Abstract

Closure device (2) for pressure cylinders (6) which store extinguishing fluid (4), with a pressure cylinder (6) and with an adapter piece (8) for connection of an immersion tube (10) arranged in the pressure cylinder (6) to a connecting piece (12) arranged outside the pressure cylinder (6). To ensure frost resistant operation of a fire extinguisher, it is suggested that the immersion tube (10) and the connecting piece (12) be formed in such a way that the connecting piece (12) is partly filled with extinguishing fluid (4) in an idle state, the connecting piece (12) has a riser pipe (14) such that the riser pipe (14) lies at least partly above the level (16) of the extinguishing fluid (4), and that the riser pipe (14) has a bursting disk (18) such that a gamma space (20) is formed between the bursting disk (18) and the extinguishing fluid (4).

Description

technical field [0001] The invention relates to a closing device for a pressure bottle used for storing fire extinguishing liquid. The closing device comprises a pressure bottle and an adapter, and the adapter is used for connecting a submerged pipe arranged inside the pressure bottle and a pipe arranged outside the pressure bottle. connectors. Background technique [0002] For example, EP 0 138 195 A2 discloses closures for pressure bottles for storing fire extinguishing liquids. The device is an automatic trigger fire extinguishing device for instruments threatened by fire. Install a small pressure bottle on the instrument, and spray the fire extinguishing liquid at the appropriate position through the blast pipe. In order to prevent the extinguishing liquid from evaporating, the blower tube is closed at its end by a material which dissolves or liquefies when a predetermined temperature is exceeded. This causes an automatic trigger. The blast pipe is filled with exting...
