Background

Fire hydrant, formally called fire hydrant, is a fixed fire-fighting equipment, and is mainly used for controlling combustible materials, isolating combustion-supporting materials and eliminating ignition sources. The indoor fire hydrant and the outdoor fire hydrant are separated. The fire hydrant set is generally formed by combining a fire hydrant, a fire hose, a water gun, a connecting buckle, a bolt, a clip and the like, and the fire hydrant is mainly used for a fire truck to take water from a municipal water supply pipe network or an outdoor fire water supply pipe network to extinguish fire, and can also be directly connected with a water hose and the water gun to extinguish fire; therefore, the indoor and outdoor hydrant system is also one of important fire fighting facilities for extinguishing fire.

It is widely considered that the fire can be extinguished by discharging water immediately as long as the fire engine reaches the fire scene. In fact, a substantial portion of fire engines equipped in fire brigade facilities are water-free, such as elevating fire engines, rescue vehicles, fire scene lighting vehicles, etc., which must be used with fire extinguishing engines. Some fire-fighting vehicles have limited water carrying capacity, and a water source needs to be searched for rapidly during fire extinguishment. At this time, the hydrant plays a great role in supplying water.
