摘要： A valve comprises: a housing defining a chamber; a fluid outlet defined by a fluid outlet wall; and a first fluid outlet orifice and a second fluid outlet orifice comprising a rigid seat. The valve comprises a movable gate, that is flexible and/or compressible and impermeable. The moveable gate is more flexible than the rigid seat, has a planar surface, and is configured to slidably move in a first axis. The movable gate is configured to be positioned so that it is located between a fluid inlet orifice and the second fluid outlet orifice when the valve is in a closed position, wherein fluid pressure within the chamber causes the movable gate to seal the second fluid outlet orifice via the rigid seat, and not the fluid inlet orifice. The valve may employ gate shapes that generate and/or exploit Bernoulli effect forces when fluid passes though the valve.

摘要： A target opening degree estimator estimates a target opening degree estimation value as an opening degree of a valve element of a pressure adjustment vacuum valve when a pressure of a vacuum chamber connected to the pressure adjustment vacuum valve reaches a pressure adjustment target pressure based on a correlation between the opening degree of the valve element and the pressure of the vacuum chamber, a current opening degree, and a current pressure.

摘要： A valve comprising a valve spindle housing located in the side of the chamber and including a first fluid inlet and a first fluid outlet, and a cylinder open along a portion of a longitudinal axis of the cylinder and rotatably mounted in the valve spindle housing. The cylinder is positioned in one position so that the cylinder completely obstructs the valve spindle housing outlet, not allowing any fluid to pass around the cylinder. The cylinder walls are solid except for having openings through a portion of the cylinder, so that when rotated to a closed position, the solid portion of the cylinder fully obstructs the valve spindle housing outlet, and when rotated to an open position, the first fluid can pass into the inside of the cylinder and then through the openings and out of the valve spindle housing.

摘要： A method of controlling an operation of a toilet system on-board an aircraft is disclosed. The toilet system includes a toilet bowl, a fluid valve controlling input of fluid into the toilet bowl, a flush switch configured to be activated by a user, and a controller configured to operate the fluid valve. The method includes detecting an activation of the flush switch, monitoring a flush switch activation time period, and determining whether the flush switch activation time period exceeds a preset threshold time period. In response to determining that flush switch activation time period does not exceed the preset threshold time period, a standard flush cycle is initiated. In response to determining that the flush switch activation time period exceeds the preset threshold time period, a maintenance mode is initiated allowing a larger volume of fluid to fill the toilet bowl for maintenance.

摘要： A device for forming at least part of a head part of a liquid treatment apparatus is arranged to receive a connecting head of a replaceable liquid treatment cartridge and includes at least one ratio-setting valve. The ratio-setting valve is provided with at least two first ports, each placeable in essentially sealed liquid communication with respective cartridge ports of a connecting head of a replaceable liquid treatment cartridge inserted into the device, and with at least one second port. The ratio-setting valve includes at least one movable regulating part for setting a volumetric flow rate ratio between a first flow of liquid between a first of the first ports and the at least one second port and a second flow of liquid between a second of the first ports and the at least one second port at any of a plurality of values.

摘要： A valve (1), in particular a vacuum valve, having at least one valve housing (2), at least one closure element (3), and at least one valve seat (4). The valve seat (4) surrounds at least one valve opening (5) of the valve (1), and the closure element (3) can be moved back and forth between at least one open position, in which the closure element (3) at least partly releases the valve opening (5), and a closed position, in which a sealing surface (8) of the closure element (3) is pressed against the valve seat (4) in order to close the valve opening (5), by at least one closure element drive (6, 7). At least one surface (9) of the valve (1) has an average surface roughness RZ less than or equal to 0.4 um, preferably less than or equal to 0.25 um.

摘要： A bleed valve for a gas turbine engine compressor has a valve body and a flapper. The valve body defines a flow path and includes a flapper seat. The flow path extends through the valve body. The flapper is pivotally connected to the valve body and is movable between a closed position and an open position. In the closed position the flapper seats against the flapper seat and blocks the flow path. In the open position the flapper is angled towards the valve body inlet such that fluid moving through the valve body exerts force on the flapper, urging the flapper towards the closed position.

摘要： An air discharge valve comprises a pipe connection base, a rotary member, at least one seal member and a buffer member. The pipe connection base comprises at least one pipe member which comprises an orifice; the rotary member and the buffer member are both axially connected with the pipe connection base to rotate about a rotation axis relative to the pipe connection base; the rotary member comprises at least one operational part, and the at least one seal member is connected with the rotary member and corresponded to the orifice; the buffer member comprises at least one corresponding operational part, and a rotation buffering space is reserved between each corresponding operational part and each operational part. When the rotary member is at a first orientation relative to the pipe connection base, each seal member correspondingly seals and closes each orifice; when the rotary member is driven by the buffer member and rotated to a second orientation relative to the pipe connection base, each seal member is removed from each orifice so that air in each pipe member can be discharged from the corresponding orifice.
