FIRE HYDRANT EQUIPMENT IN TUNNEL

PROBLEM TO BE SOLVED: To remotely open a separately-disposed hydrant valve by an operation of a hydrant valve opening/closing lever in a hose storage part side without any necessity of mechanical connection such as a wire link.SOLUTION: A hydrant valve 72 separately disposed from a hose storage part, includes a valve opening/closing mechanism that is opened by application of a pilot pressure by a supply of a fire-fighting water to a cylinder chamber 80, and that is closed by reduction in the pilot pressure by discharge of the fire-fighting water from the cylinder chamber 80. A manual pilot valve 90 is disposed at a hose storage part side and, by opening operation of the manual pilot valve 90, the fire-fighting water is supplied via pilot pipes 86a and 86b to the hydrant valve 72. This configuration can remotely open the hydrant valve by application of the pilot pressure.SELECTED DRAWING: Figure 4 【課題】ワイヤーリンク等の機械的な連結を必要とすることなく、ホース収納部側の消火栓弁開閉レバーの操作により、分離配置された消火栓弁を遠隔的に開放可能とする。【解決手段】ホース収納部に対し分離配置された消火栓弁７２は、シリンダ室８０に対する消火用水の供給によるパイロット圧の加圧で開放され、シリンダ室８０からの消火用水の排出によるパイロット圧の減圧で閉鎖される弁開閉機構を備える。手動パイロット弁９０はホース収納部側に配置され、手動パイロット弁９０の開操作によりパイロット配管８６ａ，８６ｂを介して消火用水を消火栓弁７２に供給してパイロット圧の加圧で遠隔的に開放させる。【選択図】図４
