Embodiment Construction

[0024] Certain examples are shown in the above-identified figures and described in detail below. In describing these examples, like or identical reference numbers are used to identify identical or similar elements. The drawings are not necessarily to scale and certain features and certain views in the drawings may be shown exaggerated in scale or schematically for clarity and / or conciseness. Additionally, several examples are described throughout this specification. Any feature from any example may be included with, substituted for, or otherwise combined with other features of other examples.

[0025] Examples described herein relate to a fluid valve having a trim assembly including an array of side branch resonators. Such side branch resonator arrays allow the trim assembly to absorb or attenuate noise generated by the pressure relief elements of the trim assembly. Examples described herein substantially reduce the amount of noise generated by the pressure relief member of...

Abstract

A fluid valve includes a valve body having a fluid inlet and a fluid outlet. A fluid passageway connects the fluid inlet and the fluid outlet. A trim assembly is located within the fluid passageway and the trim assembly cooperates with a control member to control fluid flow through the fluid passageway. The trim assembly includes a cage and a cage retainer. The cage retainer is located downstreamof the cage and the cage retainer and the cage are aligned longitudinally within the fluid passageway. The cage retainer includes a side branch resonator array.

Description

technical field [0001] The present disclosure relates generally to fluid valves and, more particularly, to trim assemblies including side branch resonator arrays for fluid control valves. Background technique [0002] Control valves are commonly used in process plants to control the flow of fluids (eg, gases, liquids, etc.) or any other substance through pipes and / or vessels to which they are connected. Control valves generally consist of one or more inlets and outlets, and include a fluid control element or member (e.g., valve, piston, plug, control member, etc.) ground to the outlet. The control member is typically coupled to a bonnet that is mechanically coupled (eg, bolted, clamped, threaded, etc.) to the valve body. Typically, the control member is configured to engage a sealing structure (eg, a valve seat) surrounding a flow path through the valve. [0003] Generally, the control element, including the fluid control member, seat and cage (if present) is referred to ...
