The present invention relates to a cobra automatic fire extinguishing device capable of loading a fire extinguisher. The cobra automatic fire extinguishing device can automatically spray extinguishing fluid to a location of a fire by mounting a fire extinguisher inside, detecting the location of the fire, and directing the nozzle to the location of the fire. In addition, the cobra automatic fire extinguishing device can be installed economically since it does not require additional cost and time for manufacturing a separate, dedicated fire extinguisher and certification procedure. Furthermore, the cobra automatic fire extinguishing device can effectively extinguish a fire by precisely spraying the extinguishing liquid to the location of the fire, and can prevent conflagration by suppressing the initial fire.

A fire-protection system for delivering a fire-control fluid includes a valve having a body with an inlet, an outlet, and a fluid passageway connecting the inlet with the outlet. A seal member is supportable across the passageway to close the passageway. The seal member is supported across the passageway in a sealing position in a pre-activation condition of the valve. The seal member is movable from the sealing position to a fluid-flow position in an activated condition of the valve. The seal member includes a support body having a longitudinal axis, a seat, a leading surface facing in an upstream direction from the seat, and a trailing surface located in a downstream direction from the seat and contoured radially inwardly in the downstream direction. A Belleville washer is mounted on the seat of the support body.

The invention concerns a fire extinguishing device (1; 1) for installation in a room (200) and for fighting fires in a plurality of sectors of the room, comprising a housing (7) having an extinguishing fluid inlet (3), wherein the housing has a plurality of extinguishing fluid outlets (5a-f) connected fluidically to the extinguishing fluid inlet.

According to the invention it is proposed that the extinguishing fluid outlets (5a-f) are adapted to discharge an extinguishing fluid along a respective individual extinguishing fluid trajectory (101a-f), are oriented fixedly on the housing in such a way that the extinguishing fluid trajectories from the extinguishing fluid outlets cover respectively different sectors (203a-f) of the room, and associated with the extinguishing fluid outlets is a respective control member (17a-f) for selectively opening or closing the connection between the extinguishing fluid inlet and the extinguishing fluid outlet.

A system of reducing the spread of wildfires is provided. The system includes a fire retardant delivery system comprising one or more reservoirs containing a fluid under pressure and one or more distribution devices in fluidic communication with a single reservoir. One or more sensors for sensing characteristics of a fire may be configured in operable communication with the reservoirs and/or the distribution devices, such that upon direction from the sensors the fluid can be delivered to ambient surroundings. In addition, the system may include one or more conduits between the reservoir of fluid and the distribution devices, such that the conduits can elevate the distribution devices above surrounding buildings and vegetation to provide that the fluid is distributed about the reservoir without the surrounding building or vegetation interfering therewith.

A method of and apparatus for automatically suppressing a detected fire in a building, vessel or vehicle, using a cloud of microscopic droplets generated from a supply of environmentally-clean water-based free-radical chemical-reaction interrupting liquid, whereby the droplets are vaporized by heat energy from the fire, instantly cooling the fire and displacing oxygen, while the water-based chemical vapor interrupts the free-radical chemical-reactions in the combustion phase of the fire, while minimizing smoke development, water damage, and risk of fire re-ignition.
