Claims (1)
- 一次側流路と二次側流路とを仕切る弁座に対して接離可能に配設された加圧流体が供給されると開放される主弁を有し、該主弁の開度を変化させて、該一次側流路から該二次側流路に流れる流体の流量を調整する制御弁において、
上記主弁に上記加圧流体として一次側流路の消火用水を供給して上記主弁を起動するモーターバルブと、
上記二次側流路に絞り口としてのオリフィスを設け、
該オリフィスの上流側の圧力が該オリフィスの下流側の圧力に対して所定値だけ大きい圧力になるように上記主弁の初期開放から全開まで上記加圧流体の供給を調整して上記主弁の開度を制御する調圧パイロット弁を備え、上記オリフィスの下流側が充水完了するまで主弁を全開させないことを特徴とする制御弁。
