The pressure reducing and stabilizing valve is connected to the end of the nitrogen delivery pipe, and a spray pipe is arranged on the side of the container valve. The container valve controls the fire extinguishing gas in the fire extinguishing agent bottle 12 to be output from the spray pipe.

[0021] The manifold 2 is composed of a plurality of first pipelines 21 and a plurality of first solenoid valves 22. The number of the first pipelines 21 and the first solenoid valves 22 is set according to the actual length of the manifold 2. The first pipelines 21 and the first solenoid valves 22 are arranged at intervals. The first pipeline 21 is provided with a convex pipe 31. A second solenoid valve 23 is arranged between the convex pipe 31 and the first pipeline 21. A chamber is formed in the convex pipe 31. A right exhaust valve is arranged on the side wall of the convex pipe 31. The valve is opened only after the detection is completed and the second solenoid valve 23 is closed. The leak detection component 3 is used to detect the air pressure in the chamber. Specifically, the leak detection component 3 is an air pressure sensor 32. The air pressure sensor 32 is located above the convex pipe 31 and the detection end extends into the chamber. A light alarm 33 is arranged on the convex pipe 31. The light alarm 33 is electrically connected to the air pressure sensor 32. The other end of the first solenoid valve 22 located at the end of the manifold 2 is connected to the intake pump. Specifically, the intake pump inflates the manifold 2.

[0022] Working principle: the bottle head valve is closed, and then the air intake pump is restarted into the collecting pipe 2. The first solenoid valve 22 and the second solenoid valve 23 in the collecting pipe 2 are opened from right to left in sequence. Air is taken into the convex pipe 31 on the first pipeline 21. The air pressure sensor 32 senses the entry of gas, and the air pressure value continues to rise to reach the set value, indicating that there is no leakage in this section of the first pipeline 21. If the air pressure sensor 32 in the corresponding area of ​​this section of the first pipeline 21 and the subsequent air pressure sensors will show abnormal air pressure values, then the light alarm 33 starts to alarm, so that the maintenance personnel can determine the specific location.

[0023] Example 2

[0025] Working principle: the bottle head valve is closed, and then the air intake pump is restarted into the collecting pipe 2, the first solenoid valve 22 and the second solenoid valve 23 in the collecting pipe 2 are opened in sequence from right to left, and air is taken into the convex pipe 31 on the first pipeline 21, and the movable plate 34 is pushed by the gas to touch the push-type contact switch 35, indicating that there is no leakage in this section of the first pipeline 21, and the light alarm 33 stops the alarm. If the movable plate 34 in this section of the first pipeline 21 does not hit the push-type contact switch 35, the light alarm 33 will continue to alarm, so that the maintenance personnel can determine the specific location.
