摘要： A floor nozzle assembly and systems and methods thereof for delivering a fire suppressant foam to a protected area. The nozzle assembly has a body and deflector in contact with one another to form a plurality of passageways through which a fire suppressant flows. The deflector has a deflector flange and a plurality of projecting members in contact with the body to form the passageways. The nozzle assembly has one or more of the following: i) a radial outer portion at each projecting member having a plurality of curved edges with at least two different curvatures; ii) each passageway is formed by parallel planar sidewalls; iii) the projecting members extend radially over a majority radial length of the deflector flange; and/or iv) the deflector flange has, with respect to a horizontal, a surface at an angle that is less than a support surface of the nozzle body.

摘要： The present invention discloses a device for testing control of polymorphic foam on flowing fire, comprising a test bench, a combustible liquid injecting mechanism and a polymorphic foam spraying mechanism. The combustible liquid injecting mechanism and the polymorphic foam spraying mechanism are relatively arranged on the test bench. The combustible liquid injecting mechanism can spray combustible liquid to the test bench. The polymorphic foam spraying mechanism can spray polymorphic foam to the test bench, and the spraying direction of the polymorphic foam is relative to the spraying direction of the combustible liquid. The present invention can be used for testing and observing cut-off and control effects of polymorphic foam on combustible liquid flowing fire.

摘要： An apparatus and method directed to aspirated-type high-expansion foam generation having a nozzle manifold configured to receive a foam solution and at least one nozzle assembly. The generator includes a foam generator assembly disposed adjacent the nozzle manifold. The foam generator has a body portion having a first foam generating portion and a second foam generating portion that is connected to the first foam generating portion. The generator is configured with a main header of the nozzle manifold disposed orthogonal to at least one sub-header; less than six nozzle assemblies; a ratio of a diameter of an inlet of a respective nozzle to a distance from an inner wall surface of the header to the inlet of the respective nozzle is 0.8 or less; and a nozzle with a nozzle insert with a crossover path defined by a non-sharp transition member and a cone shaped tip.

摘要： The invention relates to an optimized foam former (1) for foaming a foam-water concentrate, which foam former consists of a curved grate having diamond-shaped openings (13) and sharp edges (12). The structure of the foam former increases the foam formation and ensures uniform distribution of the foam over a large area. Existing water sprinklers having a nozzle (3) and a spray disk (2) can be provided with the foam former (1) and thus converted into foam sprinklers in a simple manner. The foam former (1) is arranged in such a way that the foam former (1) protrudes beyond the spray disk (2) toward the nozzle (3).

摘要： An autonomous grid storage system (1) with a foam based fire prevention system. The autonomous grid storage system is in the form of a grid storage structure (104) dived into sub grids (10A, 10B, 10C) separated by firebreak or firebreaks (12). A foam dispensing system (20) dispenses a fire-retardant foam into the firebreak or firebreaks in the event of fire.

摘要： A helipad fire suppression system includes a helipad having an outer boundary that defines an impervious deck area for at least one of landing or storing one or more helicopters, with at least a portion of the impervious deck area being designated a fire suppression target area. The system includes a nozzle assembly having a spray-type nozzle for spraying a fire suppression fluid in a radial pattern. The nozzle assembly can include a nozzle enclosure for enclosing the spray-type nozzle and can be configured for installation in a surface made of an impervious material. The nozzle assembly is disposed in an interior portion of the impervious deck area so as to provide the fire suppression fluid to the fire suppression target area.

摘要： This invention relates to any field where crafts (such as avionics) where inhabitants of volumes like passage compartments can be found where the area is subject to extreme conditions such as explosion, fire or other traumatic activity linked with a crash, and more specifically a pressurized dual-compartment canister or anti-trauma apparatus for the storage, mixing, and blast-release of a neutralizing chemical compound within the environment of the volume in a craft placed adjacent to the volume for the blast release of a quickly expanding and quickly retracting product.

摘要： A stillwell/siphon system may be attached or integrated into a foam delivery bucket. When pouring foam additive into the bucket, foam/bubbles may form in the foam additive. The stillwell may fill from the bottom to prevent the foam/bubbles from getting inside the stillwell tube so one can easily ascertain the level of foam in the container. The stillwell also blocks air pockets, formed from pouring foam into the container, from entering the outlet tube, which is positioned inside the stillwell.
