A water-saving sheet and a water-saving device having the same is provided. The water-saving sheet includes a sheet body including a central assembling base and a plurality of through holes arranged around the central assembling base. A circumference of the sheet body has an engaging flange structure for being positionably engaged with an inner wall of a tube. An elastic ring is annularly arranged on the central assembling base. The elastic ring and the central assembling base form at least one first passage therebetween, the elastic ring and each said through hole form a second passage therebetween. The water-saving device includes one said water-saving sheet and a barrel member. An inner wall of the barrel member has a shoulder portion engageable with the engaging flange structure to restrict the sheet body from moving toward and out from the inlet end.

A flow limiter component including a monocoque body having first, second, and third sections along a longitudinal axis. The first section includes a first end defining a first edge of the monocoque body and a bordering second end, and a first inner diameter defining a first chamber inside the first section. The second section includes a solid wall, with an orifice disposed therein, in fluid communication with the first chamber, the orifice defined by a second inner diameter. The third section includes a third end bordering the second section and a fourth end defining a second edge of the body, and a third inner diameter, the third inner diameter defining a second chamber in the third section. The second chamber is in fluid communication with the orifice. The first inner diameter is greater than the third inner diameter, and the third inner diameter is greater than the second inner diameter.

A multi-hole orifice plate for flow control includes an orifice plate for controlling the flow rate of a fluid, wherein the opening area of one orifice necessary for the passage of a predetermined flow rate of fluid is divided to provide a plurality of orifices having a total opening area equal to said opening area.

A water processor is provided for processing or conditioning water to be distributed downstream of the water processor. The water processor includes a housing having an inlet and an outlet opposite the inlet. The water processor includes a conditioning element disposed inside of the housing between the inlet and outlet. The conditioning element includes a plurality of plates having apertures with sharp edges to direct the flow of water and facilitate splitting of small gas bubbles into even smaller nano-bubbles. The plurality of plates include a first plate having a first configuration of apertures and a second plate having a second configuration of apertures. The first and second plates are disposed in alternating spaced arrangement along the longitudinal axis of the housing. The second configuration is different from the first configuration such that the flow path through the water processor is circuitous or substantially indirect.

A throttling component and a conditioning and flowrate measurement device including a throttling component. The throttling component comprises a central throttling element and multiple peripheral throttling elements. The multiple peripheral throttling elements are sequentially sleeved on the exterior of the central throttling element, and are coaxial to the central throttling element; annular fluid channels are respectively formed between the central throttling element and its adjacent peripheral throttling element, and between adjacent peripheral throttling elements. A sensitive and clear differential pressure signal is generated while the throttling component stabilizes the flow, so that the accuracy and reliability of flowrate measurement can be improved.

Implementations of an orifice plate configured to regulate a fluid flow are provided. An example orifice plate is configured to be positioned in a conduit and comprises a plurality of holes that extend therethrough. The plurality of holes are arranged to form one or more spiral layouts configured to regulate a fluid flow passing therethrough. Each spiral layout is a logarithmic spiral. In some implementations, each spiral layout has a growth factor of substantially 1.618 for each quarter turn. In some implementations, each hole in an orifice plate has a contoured conical shape extending between an inlet and an outlet, the inlet is larger in diameter than the outlet.

The hydraulic snubber insert can have an elongated stem and at least one segment extending transversally from the stem, each segment having a size and shape mating a cross-sectional size and shape of the liquid carrying line, and at least one aperture, the insert being configured for the at least one segment to be pushable snugly into the liquid carrying line and pullable out from the liquid carrying line via the stem.

An environmental control system for an aircraft includes a first conduit, a second conduit, and a connector assembly. The connector assembly is coupled to the first conduit and the second conduit for controlling a flow of air. The connector assembly includes a connector, a connector ring, and an orifice plate. The connector includes at least one wall including a ridge defining a receptacle and a connector slot defined within the ridge. The connector ring is attached to the connector and defines a connector ring slot and a covering portion. The connector ring slot aligns with the connector slot and the orifice plate is inserted into through the connector ring slot and the connector slot into the receptacle during installation of the orifice plate. The covering portion covers the connector slot and retains the orifice plate within the receptacle during operation of the environmental control system.

A method of retrofitting an environmental control system of an aircraft includes inserting the orifice plate through the connector slot and the connector ring slot into the receptacle. The method also includes aligning the covering portion with the connector slot.

A flow restrictor element, especially for restricting the air flow in an air duct system of a vehicle, comprises a ring-shaped restrictor element carrier (12) to be arranged on a flow guide duct as well as at least one restrictor element (28). The at least one restrictor element (28) is arranged within the restrictor element carrier (12), radially inwardly in relation to a central axis (M) of the flow restrictor element (10) and is detachable from the restrictor element carrier (12) for changing a restriction cross-sectional area, wherein a locking device (16) is provided on an outer circumferential area (14) of the restrictor element carrier (12) for locking the restrictor element carrier (12) on a flow guide duct.
