  • Patent number: 11773996
    Abstract: A relief valve device having a spring, a valve bonnet, a valve stem, a disc holder, a valve disc, a huddling chamber, a blowdown ring, and a nozzle. In the valve device, the valve disc is positioned above the nozzle; the spring is disposed in the valve bonnet; the spring surrounds the valve stem such that a longitudinal axis of the spring and a longitudinal axis of the valve stem are coaxial; the disc holder surrounds an outer periphery of the valve disc and is adjacent and in direct contact with a surface of the valve disc around an entire perimeter of the valve disc; the blowdown ring is disposed at a top section of the nozzle; a bottom section of the nozzle is connected to a bottom surface of a valve body and the top section of the nozzle is connected to the valve disc; and the disc holder is filled with oil.

  • Patent number: 11773995
    Abstract: A relief valve device having a valve disc positioned above a nozzle, a disc holder surrounding an outer periphery of the valve disc, and a spring surrounding a valve stem. A bottom section of the nozzle is connected to a valve body and a top section of the nozzle is connected to the valve disc. An interior surface of the nozzle contains at least one groove having a circular cross-sectional profile. The relief valve device prevents flow through the nozzle when a pressure at an inlet of the nozzle is below a predetermined force of the spring. When the pressure exceeds the predetermined force of the spring the valve stem is moved linearly through the longitudinal axis of the spring to displace the valve disc from sitting atop the nozzle and permit flow through the nozzle.

  • Patent number: 11162694
    Abstract: A system and method to dehumidify atmospheric air includes a convergent conduit, a separation unit, and a divergent conduit. A volume of humid atmospheric air enters the convergent conduit through an entry point of a convergent nozzle of the convergent conduit. A swirling process, which generates a centrifugal force, pushes a volume of water droplets towards an internal wall of the separation unit. In particular, the volume of water droplets is produced from the volume of humid atmospheric air. An annular channel of the separation unit is used to extract the volume of water droplets pushed to the internal wall of the separation unit. In particular, a drainage system which is in fluid communication with a transfer channel is used to extract the volume of water droplets from the system. A volume of dehumidified air, which is produced by removing water vapor, exits the system at the divergent conduit.
