The fire protection system includes outdoor hydrant system, indoor hydrant system, fire extinguisher system, some also have automatic sprinkler system, water cannon system, gas fire extinguishing system, fire detection system, water mist system and so on. Fire hydrant set is generally composed of fire box + fire hose + water gun + connection + bolt + clip, etc. Fire hydrant is mainly used for fire trucks to take water from municipal water supply network or outdoor fire supply network to carry out fire fighting. It can also be directly connected with water hose and water gun to put out fire. Therefore, the indoor and outdoor hydrant system is also one of the important fire-fighting facilities
Indoor hydrant is an indoor pipe network to supply water to the fire site, with the valve interface for factories, warehouses, high-rise buildings, public buildings and ships and other indoor fixed fire facilities, usually installed in the hydrant box, with fire hose and water gun and other equipment supporting use. Reducing pressure and stabilizing pressure type fire hydrant is one of them.
The outdoor fire hydrant is a water supply facility installed outside the building's fire water supply pipe network. It is mainly used for fire trucks to take water from the municipal water supply pipe network or outdoor fire water supply pipe network for fire extinguishment.
Therefore, the outdoor fire hydrant system is also one of the important firefighting facilities for fighting fires.
