Claims

[Scope of utility model registration request]

A cylindrical tube 4 curved at 45 to 90 degrees is connected to the downstream side of a form maker 3 formed with an orifice 1 and an air suction hole 2 on the side, and a thin wall is woven inside the cylindrical tube 4. A case 12 with a concave cross section of appropriate length holds a holding contact material 5 formed of a wire mesh or a perforated plate, has a fixing plate 10 on one side of the upper plate 8, and a foam reflecting plate 11 on the other side. A bubble guiding opening 13 is formed in the upper part of the fixing plate 10 to communicate with the outlet opening 7, and a foam reflecting plate is formed in the lower part of the fixing plate 10 at an angle of 4 to 9 degrees with respect to the vertical line. A foam guiding inclined plate 14 is provided by bending the foam guiding inclined plate 14 at an angle to the 11 side, and a mounting piece 16 is provided by bending the lower part of the bubble guiding inclined plate 14 so as to be on the same perpendicular line as the foam reflecting plate 11. An embedding point 17, which is a slit with an elongated rectangular cross section, is provided between the lower end of the reflecting plate 11 and the bubble guiding inclined plate 14, and the bubble reflecting plate 1
A square foam outlet 18 is provided at the lower part of the 1 to form a deflector 19, and the deflector 19 is fixed to the cylindrical tube 4, and a mounting piece 16 is fixed to the tank side wall plate 15 to prevent bubble reflection. A foam fire extinguishing system for a liquid combustible storage tank, in which a plate 11 and a tank side wall plate 15 are located on the same vertical line.
