Description

A petrochemical storage tank fire sprinkler device

technical field

The utility model relates to fire-fighting supplies, in particular to a fire-fighting spray device for petrochemical storage tanks.

Background technique

There are fire hydrants everywhere in the city to provide water for firefighters during the rescue process. The main function is to control combustibles, isolate combustion aids, and eliminate ignition sources. The fire protection system includes outdoor fire hydrant system, indoor fire hydrant system, fire extinguisher system, and some automatic sprinkler systems, water cannon systems, gas fire extinguishing systems, fire detection systems, water mist systems, etc. The fire hydrant is mainly used for fire trucks to take water from the municipal water supply pipe network or outdoor fire water supply pipe network to put out the fire, and it can also be directly connected to the water belt or the water gun to put out the fire.

At present, the fire sprinkler will break down or even break during use, making the room wet, the ground slippery, or even damage the ground. It is difficult to close it in time, resulting in losses.
