The indoor fire hydrant is an important part of the fire water system. It is installed in the indoor fire box. The general nominal diameter (mm) is DN50 and DN65, the nominal working pressure is 1.6MPa, the strength test pressure is 2.4MPa, and the applicable medium is clean water and foam mixture.
Indoor fire hydrants can usually be divided into ordinary type, pressure reducing and stabilizing type, rotating type, etc. Their fire extinguishing method is to manually connect a water hose to the hydrant mouth for extinguishing the fire. In addition, there is a fire hydrant button inside the hydrant box, which can be pressed to remotely start the fire pump to replenish water to the hydrant.
