  • Patent number: 11821583
    Abstract: A monitoring system is disclosed. The monitoring system comprises: a nozzle steam trap (3) including a supply portion (10) into which water vapor is supplied, and a discharge portion (11) which discharges liquid water contained in the water vapor; a temperature measurer (20) that measures a temperature of the discharge portion; a transmitter (24) that transmits temperature information containing the temperature measured by the temperature measurer; a receiver (7) that receives the temperature information; a determiner (8) that determines whether an abnormality is present in the nozzle steam trap based on the temperature information; and a notifier (9) that issues a notice when the determiner determines that the abnormality is present. A first discharge-side reference temperature lower than the boiling point of the water and a second discharge-side reference temperature higher than the boiling point of the water are set for the discharge portion.

  • Patent number: 11396206
    Abstract: A bicycle wheel contains a rim, multiple spokes, and multiple abutting faces. The rim includes multiple through orifices, a hub, and multiple threaded orifices. Two intersected spokes are connected with two adjacent through orifices and two threaded orifices corresponding to the two adjacent through orifices respectively. Each spokes includes a first screwing section and a second screwing section. The second screwing section is screwed with each of multiple nuts and each of multiple second screw bushings. The multiple abutting faces are connected with the multiple spokes respectively. Each spoke includes an axial line defined along a center thereof. An angle is defined between each abutting face of the rim and the axial line of each spoke and is 90 degrees. Two connection sections are formed on two ends of each abutting face.

  • Patent number: 11242954
    Abstract: A nozzle-type steam trap including a venturi nozzle, an orifice nozzle, or a tunnel structure resistance nozzle minimizes the outflow of steam even when a pressure difference between a drain-water inlet and a drain-water outlet of each nozzle fluctuates, the steam trap being compatible with any usage environments and enabling maintenance and inspection to be easily performed. The nozzle-type steam trap including the venturi nozzle, the orifice nozzle, or the tunnel structure resistance nozzle includes a means for sealing the nozzle by using a drain water. The nozzle-type steam trap further includes a plurality of steam inflow ports and drain-water outflow ports and includes a closure means for determining, for a selected one of the steam inflow ports and a selected one of the drain-water outflow ports, passages of steam and drain water. More preferably, the steam trap includes a swirl flow formation means in the vicinity of the nozzle.

  • Patent number: 9981303
    Abstract: A tube expander for heat exchanger coil units according to which a tubular expansion process is conducted. In one aspect, the tube expander includes a fixture, which includes a back unit and first and second door assemblies movably connected thereto. One or more heat exchanger coil units are adapted to be connected to each of the first and second door assemblies. In another aspect, the fixture is adjustable to accommodate different heat exchanger coil units. In yet another aspect, the tubular expansion process is not permitted when the first or second door assembly is closed and a sensor does not sense the presence of a latch bar.

  • Publication number: 20160146399
    Abstract: An orifice nozzle-type steam trap, a Venturi nozzle-type steam trap, and/or a tunnel-structured resistance tube-type steam trap are provided capable of coping with a change in the discharged amount of a drain due to, for example, a variation in the amount of steam used resulting from the operating condition of steam-based equipment, seasonal external factors and/or a variation in the working pressure difference between the inlet and outlet of a steam trap. A strainer filter can be provided that eliminates strength insufficiency due to the miniaturization of strainer screens of these nozzle-type steam traps, retains the forms of the screens, allows the screens to be easily attached to and detached from the strainers, and/or makes maintenance, such as screen cleaning, easy.
