Claims (1)
圧力に応じて開閉するパイロツト弁の開閉により
主弁体の開度を調節する減圧弁を備えた減圧弁装
置において、前記送液管路に大口径の減圧弁と、
小口径の減圧弁とを並列に配設するとともに、前
記大口径の減圧弁のパイロツト弁の設定圧力が、
前記小口径の減圧弁のパイロツト弁の設定圧力よ
りも小であることを特徴とする減圧弁装置。 In the pressure reducing valve device, the pressure reducing valve is provided in the middle of the liquid sending pipe and is equipped with a pressure reducing valve that adjusts the opening degree of the main valve element by opening and closing a pilot valve that opens and closes depending on the pressure on the secondary side of the pipe. A large diameter pressure reducing valve in the liquid pipe line,
A small diameter pressure reducing valve is arranged in parallel, and the set pressure of the pilot valve of the large diameter pressure reducing valve is
A pressure reducing valve device characterized in that the pressure is lower than a set pressure of a pilot valve of the small diameter pressure reducing valve.
