Embodiment Construction
[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0031] see figure 1 , a high-pressure cabin water sprinkler fire extinguishing system, comprising a fire-fighting water tank 14 and a pressure gauge 8, a safety valve 9 and a replenishment valve 10 arranged on the fire-fighting water tank 14; the pressure gauge 8 is provided with a water tank pressure gauge valve 7, To realize the setting of the pressure in the fire water tank 14;
[0032] The top of the fire-fighting water tank 14 communicates with the high-pressure nitrogen cylinder 1 through the pressure reducing valve 4, and the bottom of the fire-fighting water tank 14 is provided with a water outlet, and the water outlet communicates with the high-pressure nozzle 18 through the fire-fighting valve, and the hig...

The invention relates to a water spraying fire extinguishing system for a high-pressure cabin. The water spraying fire extinguishing system comprises a fire-fighting water tank, a pressure gauge, a safety valve and a water supplementing valve, wherein the pressure gauge, the safety valve and the water supplementing valve are arranged on the fire-fighting water tank; the top of the fire-fighting water tank is communicated with a high-pressure nitrogen cylinder through a pressure reducing valve, and the pressure reducing valve is communicated with a gas valve in the high-pressure cabin; a wateroutlet is formed in the bottom of the fire-fighting water tank, the water outlet is communicated with a high-pressure nozzle through a fire-fighting valve, and the high-pressure nozzle is arranged inthe high-pressure cabin; and a floating ball is arranged in the fire-fighting water tank, the diameter of the floating ball is larger than that of the water outlet, and the density of the floating ball is smaller than that of water and larger than that of high-pressure nitrogen. The pressure reducing valve is communicated with the gas valve in the high-pressure cabin, so that the pressure reducingvalve has a gas tracking function, the pressure of water in the water tank is always higher than that in the high-pressure cabin, and the fire extinguishing effect is guaranteed; the floating ball isarranged in the fire-fighting water tank, so that the functions of water passing and gas blocking are achieved according to the buoyancy principle; and a channel allowing nitrogen to flow into the high-pressure cabin is automatically cut off after the water in the water tank is used up, so that harm to people or objects in the cabin is avoided.
Description
technical field [0001] The invention relates to the technical field of fire protection, in particular to a water spray fire extinguishing system for a hyperbaric cabin. Background technique [0002] The fire extinguishing in the high-pressure manned cabin is mainly a water sprinkler system, supplemented by a portable fire extinguisher. Water spray fire extinguishing is generally carried out by using the water in the water tank under the pressure of high-pressure nitrogen gas higher than the pressure in the cabin to extinguish the fire. During the water spray process, the pressure in the water tank will gradually decrease as the water decreases; Control the pressure in the water tank to meet the normal pressure required for water spraying. When the water in the water tank is released, it is necessary to manually or electrically control the fire water valve to prevent the nitrogen in the water tank from entering the high-pressure manned cabin. This process requires manual clo...
