摘要： PURPOSE: To provide an inexpensive foam extinguisher which is suited to a small oil fire by mounting an ejection port of a foam ejection head to eject foam toward a wall surface. CONSTITUTION: When a fire occurs in oil accumulated in a pit 11 or 13 of an oil weir of a petroleum tank, heat generated breaks a glass valve at a sprinkler head 61 as heat sensing element of a heat sensitive actuating valve 6, which makes a latch come off an arm to open a clipper. As a result, an aqueous film foam extinguishing liquid 3 of a foam extinguishing agent container 2 is forced to flow by a pressure of a nitrogen gas 4 to a foam ejection head 8 through a valve 6 and an elbow 7 with a different diameter and starts a foaming with the suction of air. The foam thus obtained flows down onto the surface of the oil in the pit 11 or 13 along a wall surface 10 and accumulated thereon to extinguish the fire. The foam ejected from the head 8 is not uniform in size but when it hits the wall surface 10, the foam sucks surrounding air and a secondary foaming occurs to generate a smaller foam with a uniform particle size, thereby further enhancing extinguishing effect.

摘要： PURPOSE: To obtain an inexpensive foam extinguisher requiring no mounting work suited to small oil fires by a method wherein, when an automatic valve is opened, a foam solution and extinguishing water flow to a foam generator by a pressure gas to be mixed at a specified ratio and discharged from a nozzle and blown to a net to generate a highly bubbling foam. CONSTITUTION: A foam extinguisher 5 is constituted of a double-structured cylinder body 6, and a circular housing part 7 in the peripheral part is divided in two, i.e., a foam solution tank 9 and an extinguishing water tank 10 by a partition wall 8. When a fire occurs in a storage solution bit 3, a closed type sprinkler head 18 is thermally operated and extinguishing water in a pressure storage chamber 27 of an automatic valve 13 is discharged at the sprinkler head 18. A valve body 25 of an automatic value 13 is pushed up by the pressurized extinguishing water from the extinguishing water tank 10 to mix the foam solution and the extinguishing water with an orifice. The mixed solution is blown to a net 11 for generating a foam from a nozzle 15 through a constant flow valve 14 to be highly foamed and thus, flows into the solution storage bit 3 to be gradually accumulated thereby extinguishing a fire.
