Indoor fire hydrant
Indoor fire hydrants are generally installed inside buildings and mainly consist of fire interfaces, water guns, hoses, fire hose reels, and other components. The fire interface is used to connect the water hose and water gun, the water gun is used to spray water for extinguishing fires, the water hose is used to transport water sources, and the fire hose reel can directly use the hose for extinguishing fires when the water gun is not in use.
Outdoor fire hydrant
Outdoor fire hydrants are located outside buildings and are usually installed in public places such as roads and squares. The outdoor fire hydrant mainly consists of the body, bend pipe, valve seat, valve stem, drainage valve, valve plate, and other parts. The main body is the main part of the fire hydrant, used to support the entire fire hydrant; Bends are used to connect the body and valve seat; The valve seat is the inlet of the fire hydrant; The valve stem is used to control the switch of the valve plate; The drainage valve is used to discharge the residual water inside the fire hydrant; The valve plate controls the direction of water flow.
