また、 この発明は、加圧充水された一次側配管と二次側配管とが接続され、二次側配管内の圧力が低下すると、一次側配管から二次側配管に消火薬剤水溶液が流入するチャッキ弁機構を有する流水検知装置を備え、一次側配管には消火水を供給する水槽と、消火薬剤を供給する消火薬剤槽と、消火水と消火薬剤とを混合して消火薬剤水溶液を生成する混合器が接続され、二次側配管には消火薬剤水溶液を噴霧する閉鎖型ヘッドが接続される消火システムにおいて、一次側配管と二次側配管との間に、二次側配管内の圧力が一次側配管内の圧力より一定値以上高いときに、二次側配管内の圧力を一次側配管に逃がすチャッキ弁機構を有する昇圧防止弁が接続され、混合器の一次側に、一次側配管内の圧力が一定値以上になったときに一次側配管から排水する排水弁が設けられることを特徴とするものである。
In the present invention, when the pressurized and charged primary side pipe and the secondary side pipe are connected and the pressure in the secondary side pipe decreases, the fire extinguishing water supplied from the primary side pipe flows into the secondary side pipe. In a fire extinguishing system that includes a water flow detection device having a check valve mechanism, a water tank that supplies fire water is connected to the primary side pipe, and a closed head is connected to the secondary side pipe, the primary side pipe and the secondary side A pressure increase prevention valve that has a check valve mechanism that releases the pressure in the secondary side pipe to the primary side pipe when the pressure in the secondary side pipe is higher than the pressure in the primary side pipe by a certain value or more. A drain valve is connected to the primary side pipe and drains from the primary side pipe when the pressure in the primary side pipe becomes a predetermined value or more.
Further, according to the present invention, when the pressurized and charged primary side pipe and the secondary side pipe are connected, and the pressure in the secondary side pipe decreases, the fire-extinguishing agent aqueous solution flows into the secondary side pipe from the primary side pipe. A water detection device with a check valve mechanism is provided, and a water tank for supplying fire-extinguishing water, a fire-extinguishing chemical tank for supplying fire-extinguishing chemical, and a fire-extinguishing water and fire-extinguishing chemical are mixed to produce a fire-extinguishing chemical solution In a fire extinguishing system in which a closed-type head that sprays a fire-extinguishing chemical aqueous solution is connected to the secondary side pipe, the pressure in the secondary side pipe is between the primary side pipe and the secondary side pipe.
