WATER MIST FIRE SUPPRESSION SPRINKLER

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.

主权项

1. A water seat for use in a fire suppression sprinkler movable between an inactive position and an active position comprising:
a generally polygonal guiding surface, wherein the polygonal guiding surface is in limited contact with the sprinkler, such that the water seat slides relative to the sprinkler when a corrosion residue is present within the sprinkler; a sealing surface adjacent the polygonal guiding surface, wherein the sealing surface forms a line contact seal with the sprinkler when the water seat is in an active position; and a guiding portion adjacent the sealing surface and opposite the polygonal guiding surface, such that the guiding portion and the guiding surface retain the water seat in an orientation generally parallel to the sprinkler when the water seat moves from an inactive to an active position.
