    • A system (101) for delivering a fire retardant gel mixture. The system includes a gel tank (103), a gel pump (105) arranged to draw gel from the gel tank (103), a ring main (107) connected to an outlet of the gel pump (105) and being arranged to provide a return path for recirculating gel to the gel tank (103), and a mixing valve (113) fluidly connected within the ring main (107). The mixing valve (113) includes a first inlet port (115) arranged to receive gel from the ring main (107), a first outlet port (116) arranged to return gel to the ring main (107), a second inlet port (117) for receiving water from a water source (131), a second outlet port (123) or discharging a gel/water mixture, and a movable valve element (143) which is selectively controllable between (i) a closed position in which the gel is not mixed with the water and is instead returned to the ring main (107) via the first outlet port (115), and (ii) an open position in which the gel is not returned to the ring main (107) and is instead injected into the water and then discharged at the second outlet port (123). At least one spray nozzle (121) is connected to the second outlet port (123) of the mixing valve (113) for distributing the fire retardant gel/water mixture.
    • 一种用于输送阻燃凝胶混合物的系统(101)。 该系统包括凝胶罐(103),布置成从凝胶罐(103)抽出凝胶的凝胶泵(105),连接到凝胶泵(105)的出口的环形主体(107),并设置成提供 用于将凝胶再循环到凝胶罐(103)的返回路径,以及流体连接在环形主体(107)内的混合阀(113)。 混合阀(113)包括布置成从环形主体(107)接收凝胶的第一入口端口(115),布置成将凝胶返回到环形主体(107)的第一出口端口(116),第二入口端口 117),用于从水源(131)接收水,第二出口(123)或排出凝胶/水混合物;以及可移动阀元件(143),其可选择性地可控于(i)关闭位置,其中 凝胶不与水混合,而是经由第一出口(115)返回到环形主体(107),和(ii)凝胶不返回到环形主体(107)的打开位置,并且是 而是注入水中,然后在第二出口(123)处排出。 至少一个喷嘴(121)连接到混合阀(113)的第二出口(123),用于分配阻燃凝胶/水混合物。
