摘要:
An example vacuum-assisted toilet includes a toilet bowl including an outlet. The outlet of the toilet bowl is fluidly coupled to a first flush valve, for example, using a first pipe. The first flush valve is fluidly coupled to a second flush valve that is positioned downstream from the first flush valve. For example, the first flush valve may be fluidly coupled to the second flush valve using a second pipe. The second flush valve is fluidly coupled to a vacuum source. The vacuum source may include, for example, a holding tank having a vacuum pressure therein, a vacuum pump, or any other suitable vacuum source.

Embodiments described herein relate to quick release toilet concepts, which can be useful particularly on-board aircraft and other passenger transport vehicles. Further specific embodiments relate to a quick release rinse valve, a quick release flush valve, an integrated rinse ring, a replaceable toilet bowl, an integrated anti-siphon/rinse valve, and improved flush valve performance.
摘要:
A side-opening sleeve valve having an inner cylindrical barrel with a shaped opening through the wall, an outer cylindrical barrel having shaped opening through the wall, where the barrels are co-annular and rotatable, and a means for rotating the inner barrel relative to the outer barrel between a first open position where the shaped openings overlap to form a side opening into the sleeve valve, and a second closed position where the shaped openings do not overlap. A side-opening valve is used in pigging fluid flush system for a water-less toilet, where a toilet bowl empties into the side opening of the side-opening valve when opened. When the side-opening valve is closed, a pig cleaning system pushes the waste in the side-opening valve to a sewage system.

Various embodiments of a device for regulating a fluid flow are described that can include first and second downwardly-sloping valves that are biased in a closed position to prevent odors from escaping the device. The device can also include first and second downwardly-sloping valve seats, and configured such that an end portion of the first valve can be seated beneath the first valve seat and an end portion of the second valve can be seated beneath the second valve seat when the first and second valves are in a closed position, respectively.

摘要:
A water saving toilet system having a toilet including a toilet bowl having an upper portion and a lower portion, at least one valve interposed between a first water source and a second water source and the toilet bowl for controlling at least one volume of water flowing from the first water source and/or the second water source to the toilet bowl and a timing mechanism connected to the at least one valve for controlling an amount of time that the valve allows water to flow from the first water source and/or the second water source to the toilet bowl, wherein the at least one valve and the timing mechanism cooperate to adjust the flush volume.
摘要:
A toilet has an electronic flush assembly operable in either a short or long flush sequence selectable by a user. The long flush sequence includes a pre-rinse cycle and a rinse cycle in which the a supply valve and a flush valve are both opened and closed twice, once each first during the pre-rinse cycle and again during a subsequent rinse cycle. The rim supply valve and the flush valve are opened during the pre-rinse and rinse cycles but are closed at the start and end of each cycle. An electronic control controls operation of the valves as well as water supply control components. Level sensors can also be included to provide feedback to the controller, for example, to prevent overflow conditions.
摘要:
Plumbing fixtures with a valve actuator for automatically controlling pivoting of a flush valve, and methods of calibrating movement of the flush valve, are disclosed. The motor of the valve actuator may be positioned between the bowl of the fixture and a leg of a trapway to provide compact assembly. A belt drive laterally extending along the trapway links the motor to the flush valve. The method of calibrating includes establishing stop points which are at positions of less resistance than hard stop positions.
