摘要： The application relates to a method for producing compressed air foam for fire-fighting, wherein the method comprises the following steps: supplying a mixture of water and foaming agent via a supply line (12; 22) in a mixing chamber (11; 21) of a foaming line (10; 20), wherein a regulating device (14; 24) is disposed in the supply line (12; 22), by means of which a volume flow of the mixture can be regulated, suppling compressed air via a compressed air line (13; 23) in the mixing chamber (11; 21), wherein a further regulating device (15; 25) is disposed in the compressed air line (13; 23) by means of which a volume flow of the compressed air can be regulated, producing compressed air foam in the mixing chamber (11; 21) by foaming the mixture of water and foaming agent in the mixing chamber (11; 21) by means of the compressed air and discharging the compressed air foam from the foaming line (10; 20) via a mixing pressure regulator (17; 27) which regulates a mixing pressure in the mixing chamber (11; 21) into a delivery line (30; 40), wherein a pressure measuring device (31; 41) is disposed in the delivery line (30; 40), which records a pressure in the delivery line (30; 40) and which, like the regulating device (14; 24) and the further regulating device (15; 25), couples to the control device (26), and wherein the volume flow of the mixture of water and foaming agent and/or the volume flow of the compressed air is regulated by means of the control device (26) depending on the recorded pressure in the delivery line (30; 40). The application further relates to an apparatus for producing compressed air foam for fire-fighting.

摘要： A device for generating compressed air foam for use in fire suppression, the device may be attached to standard pressurized sources of water used for fighting fires. The device comprises a water chamber adjacent to an air chamber with a partition there between. A water impeller resides at least partially within the water chamber and an air impeller resides at least partially within the air chamber. The pressurized source of water drives the water impeller, which in turn is connected to drive the air impeller. The air impeller sucks air into the air chamber and compresses the air. The air then passes through a nozzle in the partition to aerate the source of water containing foam solutes to form compressed air foam. The compressed air foam exits the device with a velocity to coat a fire to be extinguished.

摘要： A mobile fire extinguishing device includes a motorbike having a base connected to a rear end thereof, and a foam-type fire extinguishing device is connected to the base. Two support units extend from two sides of the base respectively and each support unit has a retractable support rod. A support stand is pivotably connected to the rear end of the base and is positioned either at a retracted first position or an extended second position. When the two support rods are extended, the motorbike is lifted upward and the rear wheel of the motorbike is lifted from the ground. When the support stand is pivoted to the second position, the two support units are retracted, the support stand contacts against the ground so that the motorbike is stable on the ground to bear the reaction force due to the action of the foam-type fire extinguishing device.

摘要： A fire suppression apparatus and method of generating foam are provided in which a foam-forming liquid is introduced under high velocity and pressure into a mixing manifold through a plurality of jets, and a non-combustible gas is introduced under high velocity and pressure into the center of the mixing manifold, downstream of the jets and in the direction of flow of the foam-forming liquid. The foam generated in the mixing manifold is discharged through a hose and nozzle connected to the mixing manifold. The apparatus may be a self-contained unit, supported on a frame, with its own supply of foam-forming liquid and non-combustible gas.

摘要： A pilot valve assembly for regulating the output of a first pressure source relative to a second pressure source, a fluid system equipped with the valve assembly, and a method of operating the valve assembly. The valve assembly includes a valve body with inlet and outlet ports and first and second sensing ports. The first and second sensing ports are adapted to sense, respectively, the fluid pressures of the first and second pressure sources. The inlet port is adapted for fluidically connecting to the first pressure source. The valve assembly defines a flow path between the inlet and outlet ports, and has components for allowing fluid flow from the inlet port, through the flow path, and to the outlet port only if the fluid pressure of the first pressure source exceeds the fluid pressure of the second pressure source by a differential by the flow-allowing components.
