[0014] (2) In the present invention, as the pressure in the tank increases, part of the dry powder fire extinguishing agent enters the powder outlet pipe along with the nitrogen and is sent to the outlet valve of the dry powder cannon, dry powder gun or dry powder fixed nozzle. When the pressure at the outlet valve of the dry powder cannon, gun or dry powder fixed nozzle reaches a certain value, the valve is opened to quickly convert the pressure energy into velocity energy, so that a high-speed gas-powder flow is ejected from the nozzle of the dry powder cannon, shot towards the fire source, cutting the flame, destroying the combustion chain, and quickly extinguishing or suppressing the fire, which has the advantage of good fire extinguishing effect.

[0025] Furthermore, a diaphragm pressure gauge 12 and a tank safety valve 13 are respectively installed on the top surface of the dry powder tank assembly 7, which play a good role in pressure monitoring and safety pressure relief protection.

[0026] Working principle: When in use, a starting bottle box 5 is installed on the outside of the dry powder tank assembly 7, and a high-pressure nitrogen storage bottle 4 is installed inside the starting bottle box 5. A bottle head valve 3 is installed at the upper air outlet of the high-pressure nitrogen storage bottle 4. The bottle head valve 3 is sealed and connected to the pressure reducing valve 2 through the collecting pipe 14. The pressure reducing valve 2 is sealed and connected to the inlet ball valve 6 through a pipeline. One end of the inlet ball valve 6 is sealed and connected to the inside of the dry powder tank assembly 7 through a pipeline. The high-pressure nitrogen in the high-pressure nitrogen storage bottle 4 is reduced in pressure by the pressure reducing valve 2, so that the nitrogen quickly enters the inside of the dry powder tank assembly 7, and a part of it is sent to the bottom of the dry powder tank assembly 7, which plays the role of loosening the dry powder fire extinguishing agent.

When the pressure at the dry powder cannon, the dry powder reel 15 or the powder discharge valve 10 of the dry powder fixed nozzle reaches a certain value, the valve is opened, and the pressure energy is quickly converted into velocity energy. In this way, a high-speed gas-powder flow is ejected from the nozzle of the dry powder cannon, shot towards the fire source, cutting the flame, destroying the combustion chain, and quickly extinguishing or suppressing the fire, with the advantage of good fire extinguishing effect.
