[0002] Rail transit is a means of transportation that is widely used by people nowadays. An existing flexible high-pressure fine water mist safety system for rail transit includes multiple carriages, each of which is equipped with a three-way solenoid valve, a branch pipe and several nozzles. Multiple carriages share two water pumps and a main water pipe. Each water pump is equipped with a three-way pipe. One passage of the three-way pipe is connected to the water pump, and the other two passages are connected to the main water pipes at both ends. The two passages of the three-way solenoid valve in each carriage are connected to the main water pipe, and the other passage is connected to the branch pipe. The branch pipe extends to the top of the carriage, and is connected to several nozzles. The carriage door is provided with an anti-poison gas water mist door device, and the carriage is also provided with an explosion-proof terror water gun. After the water is discharged into the carriage, the carriage floor is easy to slip, which can easily cause panicked passengers to fall and cause stampede accidents.
