  • Patent number: 10632413
    Abstract: An automatic high-speed rotary atomizing device, comprising a rotary spray head with an upper portion and a lower portion, the upper portion is connected to pressurized fluid, the lower portion is connected to the upper portion by means of one or more spray nozzles (1, 3) or spray orifices via a bearing (56). The upper portion is stationary. When the pressurized fluid is sprayed out from the spray nozzle, part of kinetic energy of the pressurized fluid generates a counterforce that propels the entire lower portion of the spray head to rotate at a high speed, so as to convert most of the kinetic energy of the pressurized fluid into surface energy that facilitates atomization of water flow when the pressurized fluid hits against a slanted surface or slit of the spray nozzle or passes through an aperture thereof, thereby forming a large-scale atomized, dispersed and swirling system.

  • Patent number: 10493308
    Abstract: A fire suppression system in which the water supply line is fitted with repeating arrays or groups of sprinkler heads. Each array is composed of at least two side-discharge sprinklers. The side-discharge sprinklers in each array are aimed so that their coverage areas point in opposite directions. Each side-discharge sprinkler includes a lateral heat shield. The lateral heat shield has a concave heat-concentering side that focuses radiant heat toward the sprinkler's trigger, and a convex heat-scattering side that disperses radiant heat away from the trigger. In some embodiments, the array can include one or more vertical-discharge sprinklers. The vertical-discharge sprinkler may include a heat collector to facilitate early activation of its trigger.

  • Patent number: 9821180
    Abstract: A fire suppressant system is a device that uses steam/super-heated water to suppress and put out fires rather than the traditional water method. The invention uses steam/super-heated water under high pressure to blow out and suppress the fire. The wet pressurized steam/super-heated water “blows out” the fire and the pressure removes (displaces) the oxygen and spark needed for the fire to continue burning. The wet steam/super-heated water works much like water to suppress and put out the fire but the additional benefits of the pressure help to reduce the fuel (air and spark) for the fire as well.

  • Patent number: 9677691
    Abstract: In one example embodiment, a bracket for a sprinkler fitting is provided having a first flange, a second flange connected to the first flange, and a mounting flange connected to at least one of the first and second flanges. The mounting flange may for example be substantially orthogonal to the first and second flanges. One of the first and second flanges has a preferably circular hole formed therethrough, and the other has a polygonal opening formed therethrough and aligned with the circular hole. An adapter having a polygonal end is inserted in the bracket such that the polygonal end aligns with the polygonal opening so as to limit rotation of the adapter with respect to the bracket, the adapter disposing a sprinkler coupled thereto with respect to a finished ceiling surface of a structure.

  • Patent number: 9616450
    Abstract: Coat-in-place assemblies and methods to provide an aesthetically pleasing sprinkler assembly. A coat-in-place assembly includes a sprinkler body having a proximal portion and a distal portion, a thermally responsive trigger disposed adjacent the distal portion; and an escutcheon centered about the distal portion of the sprinkler body to define a void between the sprinkler axis and the escutcheon. A coating-inhibiting-cap encloses and protects the thermally responsive trigger between the sprinkler body and the cap. The cap extends into the void and is radially spaced inward relative to the escutcheon so as expose surfaces of the escutcheon for coating.

  • Patent number: 9573007
    Abstract: A fire protection sprinkler that includes a body defining an internal passageway extending along a sprinkler axis between an inlet end and an outlet end to define a passageway length and a nominal K-factor greater than 16. A deflector is supported and spaced from the outlet end by a pair of support arms. The sprinkler includes means for allowing a flow of water from the outlet end of the body. The means includes a closure assembly having a body defining a blind bore and a thermally responsive glass bulb. The glass bulb has a first end disposed within the blind bore defining a first seat diameter and a second end defining a second seat diameter. The glass bulb has a bulb length that is greater than the length of the internal passageway and a maximum wall thickness less than the difference between the bulb length and the passageway length.
