室外消火栓主要用于向消防车提供消防用水，或在室外消火栓上直接与消防水带、水枪连接进行灭火，是城市基础建设的必备消防供水设施。
Outdoor fire hydrants are mainly used to provide fire water to fire trucks, or directly connect to fire hoses and water guns on outdoor fire hydrants for extinguishing fires. They are essential fire water supply facilities for urban infrastructure construction.
（一）系统组成室外消火栓主要组成：本体、弯管、阀座、阀瓣、排水阀、阀杆和消防接口组成，它分为地上式和地下式两种，地上式上部露出地面，标志明显，使用方便，地下式安装于地下，不影响市容。
（1） The outdoor fire hydrant system mainly consists of the main body, bend pipe, valve seat, valve disc, drainage valve, valve stem, and fire interface. It is divided into two types: above ground and underground. The above ground type has an exposed upper part, obvious signs, and is easy to use. The underground type is installed underground without affecting the city's appearance.
（二）布置要求室外消火栓应沿道路铺设，道路宽度超过60m时，宜两侧均设置，并宜靠近十字路口。布置间隔不应大于120m，距离道路边缘不应超过2m，距离建筑外墙不宜小于5m、不宜大于150m，距离高层建筑外墙不宜大于40m，室外消火栓数量应按其保护半径，流量和室外消防用水量综合确定，每只室外消火栓流量按10--15L/升计算。地上消火栓设置安装明显、容易发现，方便出水操作，地下消火栓应当在地面附近设有明显固定的标志。
（2） The layout requires that outdoor fire hydrants should be laid along the road. When the width of the road exceeds 60m, they should be installed on both sides and close to the intersection. The layout interval should not exceed 120m, the distance from the edge of the road should not exceed 2m, the distance from the exterior wall of the building should not be less than 5m or more than 150m, and the distance from the exterior wall of high-rise buildings should not be more than 40m. The number of outdoor fire hydrants should be determined based on their protection radius, flow rate, and outdoor fire water consumption. The flow rate of each outdoor fire hydrant should be calculated at 10-15L/L. The installation of above ground fire hydrants is obvious, easy to detect, and convenient for water outlet operation. Underground fire hydrants should have clear and fixed signs near the ground.
（三）使用方法消火栓平时关闭，阀瓣将进水口密封，使用时先将消防车吸水管连接口径100㎜（150㎜）的接口，或将水带连接口径65㎜的接口，然而，用专用扳手打开阀门，地下管网的市政供水便流入消火栓，消防车就可直接吸水供水，水带也能直接出水灭火。使用完毕后，关闭阀门，阀体内的余水可由排水阀自动排尽。
（3） Method of use: The fire hydrant should be closed normally, and the valve disc should seal the inlet. When using, first connect the fire truck's suction pipe to a 100mm (150mm) diameter interface, or connect the water hose to a 65mm diameter interface. However, by using a special wrench to open the valve, the municipal water supply from the underground pipeline network will flow into the fire hydrant, and the fire truck can directly suck water and supply water, and the water hose can also directly discharge water to extinguish the fire. After use, close the valve and the residual water in the valve body can be automatically drained by the drainage valve.
