：Ground fire hydrant

An above-ground fire hydrant is an outdoor fire供水 facility. It is used to supply water to fire trucks or directly connect with hoses and nozzles for extinguishing fires, serving as an outdoor fire供水 facility. It protrudes above ground with clear signage and is easy to use. It is composed of components such as the body, elbow pipe, valve seat, valve disc, drain valve, valve stem, and fittings. Above-ground fire hydrants are essential urban firefighting equipment, especially in areas with fewer urban and riverfronts, to ensure firefighting flood needs. They should be installed in areas with high population density such as factories, mines, warehouses, wharfs, cargo yards, high-rise buildings, public places, etc., where conditions permit.
