摘要： A suppression unit includes a nozzle, an actuator piston, a casing, and a biasing device. The nozzle has an exterior surface, an interior bore extending along a longitudinal axis, and a plurality of discharge orifices passing from the interior bore to the exterior surface. The actuator piston includes an interior channel in fluid communication with the interior bore, the nozzle separably attached to the actuator piston. The actuator piston and the nozzle are disposed within the casing and the biasing device is compressible between the actuator piston and the casing. The discharge orifices are protected by the casing in a biased passive condition of the nozzle, and the discharge orifices are moved longitudinally out of the casing in an active condition of the nozzle.

摘要： Provides are embodiments of a sprinkler and sprinkler system. The embodiments include a sprinkler body having a fluid inlet, a seal configured to prevent fluid flow through the sprinkler body when the seal is in a first position, and a bulb configured to retain the seal in the first position, the bulb configured to break at a temperature and allow the seal to move to a second position allowing fluid flow through the sprinkler body. The bulb includes a wireless power and communication unit configured to receive a wireless activation signal, an energy storing unit configured to store energy for a heating element, a control unit operably coupled to the wireless power and communication unit and the energy storing unit, and the heating element configured to supply the energy to the fluid in the bulb responsive to a trigger.

摘要： An exemplary fire suppression sprinkler includes a housing (22) that establishes a flow path for discharging fire suppression fluid. A water seat (28) is configured to block the flow path. A polymer seal (30) is supported within the housing (22) and engages the water seat (28) for sealing an interface between the flow path and the water seat (28). A spring member (40) biases the polymer seal (30) into engagement with the water seat (28).

摘要： In one aspect, a fire suppression sprinkler assembly (10) is provided. The assembly includes a housing (20), and a sprinkler body (22) disposed at least partially within the housing and configured to supply a fluid to an area. The sprinkler body is movable between a first position where the sprinkler body is concealed within the housing and a second position where the sprinkler body extends from the housing to supply the fluid to the area heat responsive element (28) operatively associated with the sprinkler body and configured to facilitate preventing deployment of the sprinkler body from the first position to the second position until the heat responsive element senses a predetermined temperature.

摘要： A water mist fire suppression device includes a nozzle body disposed about a central axis. Also included a nozzle arrangement configured to expel water. The nozzle arrangement includes an annular groove. The nozzle arrangement also includes a micro nozzle extending from a water plenum to the annular groove, wherein the micro nozzle is angularly oriented from the central axis. The nozzle further includes a deflector lip located proximate an outlet of the nozzle, wherein the deflector lip is positioned to contact water exiting the outlet of the nozzle arrangement.
