    摘要: A tube extends through an attachment section and defines a vapor passageway. A housing is supported to the attachment section for movement between several positions relative to the attachment section. The housing defines a float chamber below the tube. A valve seat portion is located within the float chamber and has an engagement part, a sleeve part and a seat surface. The engagement part is connected to the housing. The sleeve part telescopically engages the tube and is movable along the tube with the housing. The valve seat portion defines a central bore open to the vapor passageway and the seat surface. The float moves within the float chamber. When to fluid enters the float chamber the float floats up against the seat surface closing off the central bore and the vapor passageway. In the absence of fluid the float moves downward exposing the seat surface.

    摘要: A system for and method to control and improve throughput of liquid in a sewer system utilizes a generally gas free column of sewer pipes. A single manhole has a separate section to handle waste water and a separate section to handle surface water, with pipes operatively connected to them. Valves connected to the manhole and pipes are opened and closed to prevent outlet as well as to prevent gas from entering the outlet to keep the sewer pipes filled with liquid, and fluid travels pipe-in-pipe and forms a gravity flow high capacity (full current) column.

    摘要: Disclosed herein is a trap assembly for draining waste water toward sewer pipes while blocking back flow of odors. In a preferred embodiment the trap assembly comprises of a housing having a hollow interior, open, upper and lower ends. The housing is connected to a drain pipe at the lower end and extending outwardly therefrom into a substantially vertical orientation, a valve member formed of buoyant material; a retainer assembly connected to said housing in an at least partially supporting relation to a valve member. Further the valve member disposable into and out of sealing engagement with the valve seat dependent on direction of liquid flow along a flow path.

    摘要: A backflow prevention apparatus is provided with a check valve and a float-type backflow prevention valve, these being installed in this order as one proceeds from upstream to downstream. The check valve comprises a valve seat; a valve member that closes the valve at the valve seat due to an upwardly directed restoring force; and a restoring force exerting member that exerts an upwardly directed restoring force on the valve member. The float-type backflow prevention valve comprises an annular valve seat; a float that rises in accompaniment to a rise in a water level of wastewater to close the valve at the annular valve seat; a guide member that guides movement of the float in a vertical direction; and a constraining member that constrains a lowermost position to which the float can move.

    摘要: A valve for draining off gas from a centrifugal separator includes a valve body having a central axis around which the valve may be rotated; a cavity arranged at a radial distance from the central axis and including a valve ball and a valve seat; at least one drain channel extending from the valve seat of the cavity to the outside of the valve body; and at least one gas intake extending from the outside of the valve body to the cavity. The valve ball is in a relaxed state within the cavity and thereby arranged to float on a liquid surface present within the cavity, and thereby being movable in the cavity in the radial direction from rotational axis from a closed position, in which the ball rests against the valve seat and thereby blocking gas in the cavity from entering the at least one drain channel, to an open position, in which the valve ball is at a longer radial distance from the axis compared to the closed position, and in which open position the valve ball does not block the valve seat and thereby allowing gas in the cavity to drain from the valve via the drain channel A centrifugal separator and a method for draining gas from the inlet of a centrifugal use the valve.

    摘要: A shut-off valve includes a float and a negative G control component. The float is configured to occlude a tank outlet at a first fluid level and 1 G and unocclude the tank outlet at a second fluid level and 1 G. The negative G control component is operatively connected to the float to limit fluid, e.g. liquid or gas, communication between a tank outlet and an ejector pump during negative G events. An ecology fuel return system includes a tank, an ejector pump, a float, and a negative G control component, as described above. The tank has an inlet and an outlet. The inlet is configured to be in fluid communication with components of an engine. The ejector pump is in fluid communication with the tank outlet and is configured to pump fuel from the tank to a fuel pump inlet of an engine.
