摘要： A drain system for controlling a water level in a bathtub includes a drain exit assembly coupled to an exit drain of the bathtub and configured to receive water exiting the bathtub, a valve fluidly coupled to the drain exit assembly and operably coupled to a motor, and a pressure sensor communicatively coupled to the valve and in fluid communication with the drain exit assembly. The motor is configured to change the operational state of the valve based on a pressure sensed by the pressure sensor to control a water level within the bathtub.

摘要： A drain arrangement that comprises a housing which has a first channel section with an inlet opening, a second channel section with an outlet opening, and a valve seat situated between the inlet opening and the outlet opening. It also has a valve body which is movable from the valve seat, an actuating unit to move the valve body, and an outflow pipe into which the second channel section opens. A first central axis extends centrally through the first channel section, and an outflow pipe central axis extends centrally through the outflow pipe. The outflow pipe central axis intersects the first central axis or alternatively the outflow pipe central axis is at a distance from the first central axis. The actuating unit has an actuating lever acting on the valve body, and an actuator element for actuating the actuating lever, wherein the actuator element extends laterally alongside the outflow pipe.

摘要： An intelligent drainage device includes a power supply unit, a water discharge key, drain assemblies, a motor drive unit and a control unit. The drain assembly, installed to a bathtub drain hole, includes a waterstop member, a stepping motor and a receiving tube. The receiving tube engages fixedly and oppositely the waterstop member and a power transmission shaft of the stepping motor. The control unit receives a start/stop signal from the water discharge key, then transmits the signal to the motor drive unit for controlling the power transmission shaft to drive the corresponding waterstop member to move upward or downward. In this device, with a simple touch at the water discharge key, the control unit would control the motor drive unit to activate the stepping motors so as to have all the drain assemblies at the respective drain holes to discharge simultaneously and rapidly the water inside a bathtub.

摘要： Embodiments of the present invention relate generally to a flow control unit for controlling liquid flow in a vacuum waste system. In one embodiment, the flow control unit provides a series of valves that direct liquid flow. The unit may also have an intermediate transfer tube that holds a portion of the liquid to be directed, prior to delivery of the liquid to left and right transfer tubes. In one embodiment, the unit may be installed on board a passenger transport vehicle. A particularly beneficial use of the flow control unit is on a private aircraft for use as a shower control unit.

摘要： A liquid level control system for automatically stopping the flow of water in a bathtub. The system includes an adjustable level control mechanism and a flow control device. The control mechanism comprises a float suspended from a flexible chain and slidingly mounted in a vertical chamber hydraulically linked to the bathtub. When the float is buoyantly actuated by the level of the water reaching a predeterminedly set height, the flow control device obturates the inlet of water coming from the water supply conduit.

摘要： A method and apparatus for monitoring a water level in a basin are disclosed. An automatic refill system includes a level sensor coupled to a refill valve system. The refill valve system has a valve driven by an actuator. The actuator receives a signal from a controller in response to a measured water level. The refill valve system flows water into a basin from a water source until a desired level is reached.

摘要： A system comprising: a drain fitting securable to a container for containing a liquid and an evacuation drain; and a closure member comprising: a casing; a motion device for moving the casing relative between an open position in which the casing is away from the drain fitting to allow the liquid from flowing from the container into the evacuation drain and a closed position in which the casing abuts against the drain fitting to prevent the liquid from flowing from the container into the evacuation drain; an electrical motor received in the casing for activating the motion device; a communication unit received in the casing for at least receiving a command indicative of one of an opening of the electronic drain closure system and a closure of the electronic drain closure system; and a controller for activating the electrical motor in accordance with the command received by the communication unit.
