摘要： A suppression unit includes a nozzle, a casing, and a biasing device. The nozzle includes 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 casing includes an interior surface and an exterior surface. The nozzle is disposed within the casing. The discharge orifices are covered 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. The biasing device is disposed in a spring chamber between the nozzle and the casing. The spring chamber is fluidically isolated from the nozzle in the active and passive conditions.

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： A water seat is provided for use in a fire suppression sprinkler. The water seat is movable between an inactive position and an active position. The water seat includes a generally polygonal guiding surface in limited contact with the sprinkler. The water seat is slidable relative to the sprinkler when corrosion residue is present within the sprinkler. A sealing surface is positioned adjacent the polygonal guiding surface and forms a line contact seal at an interface with the sprinkler when the water seat is in an active position. The water seat also includes a guiding portion adjacent the sealing surface and opposite the polygonal guiding surface. The combination of the guiding surface and the guiding portion maintain a generally parallel orientation of the water seat relative to the sprinkler when the water seat moves from an inactive position to an active position.
