摘要： Fire protection sprinkler assemblies and methods of use in corrosive environments. The sprinkler assemblies include a corrosion resistant sprinkler frame made of a gradient material. The gradient material includes a polymeric layer interlocked about a corrosion-prone core in order to protect the frame structure from a corrosive environment. The interlock between the core and the protective polymer layers are defined by ionic bonding between the core and the outer polymer layer.

摘要： A fire protection nozzle includes a body having two frame arms having proximal ends connected to an outlet of the body, and distal ends, the two frame arms defining a frame arm plane, and a junction formed by the distal ends of the frame arms, the junction including a central bore and an outer wall. A deflector is mounted to the body, and includes a planar member having a mounting hole in a center of the planar member to receive the outer wall of the junction, and a plurality of slots on a periphery of the planar member. The plurality of slots includes first slots, second slots, third slots, and fourth slots.

摘要： A tire protection sprinkler including a frame body having an inlet, an outlet, defining an internal passageway extending between the inlet and the outlet along a sprinkler axis. A dome shaped deflector member is centered, axially aligned with the sprinkler axis, and spaced from the outlet. The deflector member has an outer surface and an inner surface that preferably includes: a peripheral region, a central region and an intermediate region. The intermediate region includes a primary deflecting surface, and a secondary deflecting surface that is surrounded by the primary deflecting surface The deflector member provides for generation of a non-circular spray pattern defined by four zones of fluid density concentrically formed about the sprinkler axis.

摘要： A concealed sprinkler includes a body that defines an outlet, a seal that seals the outlet, an activation element coupled with the seal, a housing that defines a chamber around the activation element, a cover plate removably coupled with the housing, and a wall coupled with or extending from the cover plate to direct air flow to the activation element. The activation element changes from a first state to a second state responsive to a fire condition to allow the seal to be displaced from the outlet. The cover plate is removably coupled with the housing such that a duration of time between decoupling of the cover plate from the housing responsive to the fire condition and changing of the activation element from the first state to the second state responsive to the fire condition is less than a threshold duration of time.

摘要： A nozzle for atomizing and dispersing a discharge flow of a fluid, and a spacing plate for use in the nozzle is disclosed. The nozzle includes a bonnet, including an inlet port for receiving the fluid in the nozzle, and a first surface extending outward from the inlet port. The nozzle includes at least one deflector base, including a second surface arranged opposite to the first surface. At least one spacing plate is arranged between the first surface of the bonnet and the second surface of the deflector base. The spacing plate includes at least one gap extending through the spacing plate in its perpendicular direction (P) and extending from the outer periphery of the spacing plate to a distance (D) towards the inner section of the spacing plate. A discharge port is fluidly connected to the inlet port allowing the fluid to flow from the inlet port to surroundings of the nozzle. The discharge port is created between the first and the second surface and defined by the at least one gap of the spacing plate.

摘要： A fire extinguishing system for an energy storage device having a battery rack for a battery module, the fire extinguishing system including a sensing unit configured to detect when a value of one or more of a temperature of the battery module, a voltage of the battery module, or smoke from the battery module is higher than a preset threshold value; and a fire extinguishing unit configured to provide a fire extinguishing agent to the battery module when the sensing unit detects that the value is higher than the preset threshold value, the fire extinguishing unit including a heat-sensitive member. The heat-sensitive member is positioned at a battery cell vent hole for a battery cell in the battery module. The heat-sensitive member is configured to allow the fire extinguishing agent into the vent hole by being melted when a temperature of the heat-sensitive member is higher than a predetermined temperature.
