Systems and methods are disclosed for fire suppression. One method of fire suppression may include sensing initial environmental parameters in an area of interest, and determining whether or not to enable the fire suppression system, based at least in part on the sensed initial parameters. Then subsequently sensing subsequent environmental parameters, and determining whether to enable or disable the fire suppression system, based at least in part on the sensed subsequent environmental parameters.

A fire suppression system according to an embodiment of the present invention comprises: a detection unit for detecting a particular change due to a fire and transmitting a particular change value as a measurement value; a fire extinguishing unit for spraying a fire extinguishing substance; a control unit for receiving the measurement signal and transmitting an execution signal to the fire extinguishing unit; and a management unit enabling a user or a manager to confirm whether or not there is a fire, and for remotely operating the fire extinguishing unit, wherein the control unit transmits a notification signal to the management unit only when a measured measurement data value exceeds a threshold value, and transmits the execution signal only when an operation command is received from the management unit, thereby enhancing convenience and safety and reducing the initial cost.

A fire extinguishing system for a lithium battery energy storage unit based on stagewise warning and multiple spraying includes a power management system, a warning control system connected to the power management system and a fire extinguishing device connected to the warning control system. The fire extinguishing device is externally connected to a temperature-sensing fire detection tube, a large-flow release pipeline and a local release pipeline. The warning control system is externally connected to a local data collection module and a lithium battery energy storage pack. The fire extinguishing system of this application is designed to perform cyclical detection according to fire signals, in which a starting signal can be repeatedly sent to achieve multiple starting, so as to suppress a lithium battery fire for a long time and solve the problem of re-ignition.

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.

A fire suppression system for stoves is shown and described. The fire suppression system for stoves includes a first pressurized tank filled with a fire suppression material. The first pressurized tank is fluidly connected to a first side of a piping system. A second pressurized tank filled with a fire suppression material. The second pressurized tank is fluidly connected to a second side of a piping system. The piping system has a plurality of nozzles pointing at burners of a stove. A first temperature gauge is connected to a first release device. The first release device will dispense the fire suppression material from the first pressurized tank. A second temperature gauge is connected to a second release device. The second release device will dispense the fire suppression material from the second pressurized tank.
