    摘要： A system including a valve trim having a plurality of flow paths, wherein each flow path of the plurality of flow paths includes a series of stages, and a plurality of expansion zones disposed in series with the series or stages, wherein each expansion zone of the plurality of expansion zones is disposed between a sequential set of adjacent upstream and downstream stages of the series of stages, wherein each expansion zone of the plurality of expansion zones is configured to flow a fluid in a direction that is generally transverse to directions of flow in both the adjacent-upstream stage and the adjacent-downstream stage, and wherein each expansion zone of the plurality of expansion zones is in line with one of the adjacent-upstream stage or the adjacent-downstream stage and offset from a different one of the corresponding adjacent-upstream stage or the adjacent-downstream stage.

    摘要： A fluid-connecting element with a first receiving space with a first connecting element and a first displaceable valve element, and a second receiving space with a second connecting element and a second displaceable valve element. A fluid connection between the first receiving space and the first connecting element being interrupted by the first valve element in the first position, and a fluid connection between the first receiving space and the first connecting element being opened by the first valve element in the second position. The second valve element is displaceable between two positions, wherein a fluid connection between the second receiving space and the second connecting element is interrupted by the second valve element in the first position, and a fluid connection between the second receiving space and the second connecting element is opened by the second valve element in the second position.

    摘要： A valve includes an inlet unit including an inlet hole into which a fluid is introduced, a pressure adjusting unit which adjusts a pressure of the fluid introduced through the inlet unit, and a discharging unit having an opening and closing member which selectively discharges the fluid which had its pressure adjusted, and a water outlet hole which discharges the fluid passing through the opening and closing member to the outside, wherein a cross-sectional area of the inlet hole is greater than a cross-sectional area of the water outlet hole and a flow direction of a fluid from the pressure adjusting unit to the opening and closing member and a flow direction of a fluid from the opening and closing member to the water outlet hole are perpendicular to each other.
