The invention relates to the field of fire fighting equipment, and discloses an outdoor fire hydrant facilitating water drainage. The outdoor fire hydrant comprises a lower hydrant pipe buried underground, wherein a water passing bent pipe is connected to the bottom of the lower hydrant pipe through a flange; one end of the water passing bent pipe communicates with a water conveying pipeline; a water drainage pipe positioned underground is arranged at the bottom of the lower hydrant pipe; an upper hydrant pipe is connected to the top of the lower hydrant pipe through a flange; the middle of the top end of the upper hydrant pipe is sleeved with a threaded valve rod in a threaded mode; and a rotating wheel is arranged at the top end of the threaded valve rod. According to the outdoor fire hydrant facilitating water drainage, through the structural design of an adjusting oil pipe in linkage with the threaded valve rod, in the using process of the fire hydrant, when the threaded valve rodcontrols a valve element and a center valve seat to be opened for water pumping, a sealing ring and a water drainage valve seat are attached to block the water drainage pipe, and therefore the problemthat negative pressure formed by high-speed water flow in an inner cavity of the lower hydrant pipe causes suction of soil at a water drainage pipe opening, and consequently the water drainage pipe is blocked is solved.
本发明涉及消防设备领域，且公开了一种便于泄水的室外消火栓，包括埋于地下的下位栓管，下位栓管的底部法兰连接有通水弯管，通水弯管的一端接通有输水管道，下位栓管的底部设有位于地下的排水管，所述下位栓管的顶部法兰连接有上位栓管，所述上位栓管顶端的中部螺纹套接有螺纹阀杆，所述螺纹阀杆的顶端设有转轮。该便于泄水的室外消火栓，通过与螺纹阀杆联动的调节油管的结构设计，在消火栓使用过程中，由螺纹阀杆控制阀芯与中心阀座打开抽水时，使得密封环与排水阀座贴合封堵排水管，使得下位栓管内腔的高速水流形成的负压不会导致排水管口处泥土的吸入，堵塞排水管的问题。
