A valve trim that is configured to abate noise in a control valve. These configurations may include a cage with a flow path that has interior and exterior openings. The cage may also have a bore to receive a closure member or 'plug.' This plug can travel longitudinally to change parameters of flow through the control valve. In one implementation, the exhausts of flow paths with adjacent inlets are offset or spaced from another. In one implementation, the exterior openings vertically offset. However, other designs may adopt combinations of radial, helical, or angular offsets as well. This feature can prevent mixing of flow from jets that are in the same inlet plane. This feature, in turn, can reduce jet-to-jet interactions that may abate noise. Use of additive manufacturing may be useful (or even necessary) to create these parts within certain design envelopes because these techniques can create the unique flow geometry within a unitary or monolithic body. In this way, the valve trim of the present disclosure can maintain, or even reduce, costs of the control valve, while at the same time it can simply the overall construction of the valve device.

Using diverget flow paths in valve trim to abate valve noise

A valve trim that is configured to abate noise in a control valve. These configurations may include a cage with a flow path that has a spiral design or layout. This flow path can direct flow around a central bore. A plug may reside in this bore. This plug can travel longitudinally to change parameters of flow through the control valve. In one implementation, the spiral design can split flow inside of the cage. This feature can elongate travel of flow without any increase in dimensions of the cage (or the valve trim itself).
