  • Publication number: 20250010114
    Abstract: A helipad fire suppression system includes a helipad having an outer boundary that defines an impervious deck area for at least one of landing or storing one or more helicopters, with at least a portion of the impervious deck area being designated a fire suppression target area. The system includes a nozzle assembly having a spray-type nozzle for spraying a fire suppression fluid in a radial pattern. The nozzle assembly can include a nozzle enclosure for enclosing the spray-type nozzle and can be configured for installation in a surface made of an impervious material. The nozzle assembly is disposed in an interior portion of the impervious deck area so as to provide the fire suppression fluid to the fire suppression target area.

  • Publication number: 20240288091
    Abstract: Differential-type dry pipe valves for fire protection systems are provided. The valve includes a body with a clapper assembly disposed in an internal passage of the valve body between an inlet and an outlet. The clapper assembly is movable between a closed position and an open position to respectively prevent and permit fluid flow through the passage from the inlet to the outlet. With the clapper assembly in the open position, an internal mechanism is positioned to stop the clapper moving to the closed position. The valve includes a resetting assembly having a knob exterior to the body. Translation of the knob toward the outlet moves the internal mechanism which permits the clapper assembly to move to the closed position.

  • Patent number: 11980786
    Abstract: A proportioner having a body portion that defines a foam passage and a fluid passage. The proportioner also includes a restrictor assembly having a restrictor disk and an orifice plate having an opening for receiving the restrictor disk. The proportioner can further include a rod member connected to the restrictor disk and a clapper assembly connected to the rod member via a sliding interface. The clapper assembly can be configured to control a flow of the foam concentrate through the foam passage in proportion to a flow of the fire protection fluid through the fluid passage by moving the rod member to vary the distance between the restrictor disk and the orifice plate. The sliding interface can be disposed between a first guide and a second guide, and at least a portion of the restrictor disk is disposed in the opening.

  • Publication number: 20240009495
    Abstract: A floor nozzle assembly and systems and methods thereof for delivering a fire suppressant foam to a protected area. The nozzle assembly has a body and deflector in contact with one another to form a plurality of passageways through which a fire suppressant flows. The deflector has a deflector flange and a plurality of projecting members in contact with the body to form the passageways. The nozzle assembly has one or more of the following: i) a radial outer portion at each projecting member having a plurality of curved edges with at least two different curvatures; ii) each passageway is formed by parallel planar sidewalls; iii) the projecting members extend radially over a majority radial length of the deflector flange; and/or iv) the deflector flange has, with respect to a horizontal, a surface at an angle that is less than a support surface of the nozzle body.

  • Publication number: 20230405380
    Abstract: Fluid control valve assemblies for use in fire protection sprinkler systems to control the flow of firefighting fluid to the system sprinklers. The assemblies include a pressure-operated fluid control valve having an internal fluid chamber in which fluid contained therein acts on an internal diaphragm to control the flow of fluid from an inlet to an outlet of the valve. An environment-responsive control device in fluid communication with the internal fluid chamber along a first fluid communication line controls the flow of fluid out of the fluid chamber to initiate actuation of the valve. A fluid-flow latch in fluid communication with the outlet of the valve along a second fluid communication line subsequently controls the simultaneous flow of fluid out of the fluid chamber and the actuation of the valve.

  • Patent number: 11771936
    Abstract: A proportioner having a body portion that defines a fluid passage for transporting a fire protection fluid and a foam passage for transporting a foam concentrate. The foam concentrate mixes with the fire protection fluid to form a fire protection solution. The proportioner also includes a restrictor assembly having a restrictor disk and an orifice plate. The orifice plate has an opening for receiving the restrictor disk. The restrictor disk and opening are configured to form an annulus between an outer surface of the restrictor disk and an inner surface of the opening when at least a portion of the restrictor disk is disposed within the opening and the restrictor disk is spaced from the orifice plate. The restrictor assembly is configured to maintain the annulus for a full travel range of the restrictor disk.
