To accurately and effectively perform switching of flow channels in inspection work.SOLUTION: A fire hydrant for a road includes a switch valve for switching flow channels of fire-fighting water from an inflow port to a first flow channel used in fire-fighting activity or to a second flow channel connected to an inspection device. The switch valve includes a valve lid that moves between a first position for passing the fire-fighting water through the first flow channel and a second position for passing the fire-fighting water through the second flow channel, a pressing member for pressing the valve lid to the first position, a valve box for storing the valve lid, and a valve moving member composed integrally with the valve lid, which is disposed protruding from the valve box in a direction of the second flow channel from the valve lid. When the inspection device is connected, a pin provided in the center of the flow channel of the inspection device presses the valve moving member so that the valve lid is pressed to the second position.SELECTED DRAWING: Figure 5
【課題】点検作業時における流路の切り替えを高精度かつ効果的に行う。【解決手段】消火用水の流路を流入口から消火活動時に使用する第１の流路または点検装置に接続する第２の流路へ切り替える切替弁を有し、前記切替弁は、前記第１の流路に前記消火用水を通水する第１の位置と、前記第２の流路に前記消火用水を通水する第２の位置と、の間を移動する弁蓋と、前記弁蓋を前記第１の位置に押圧する押圧部材と、前記弁蓋を収納する弁箱と、前記弁蓋と一体に構成され、前記弁蓋より前記第２の流路の方向へ前記弁箱から突出して配置される弁移動部材と、を有し、前記点検装置が接続された場合、前記点検装置の流路の中心に設けられたピンが前記弁移動部材を押圧することにより、前記弁蓋を前記第２の位置へ押圧するようにしたこと、を特徴とする、道路用消火栓が提供される。【選択図】図５
