Noise-attenuation apparatus for pressure regulators

摘要

Noise attenuation apparatus for pressure regulators are disclosed. An example apparatus includes a first noise attenuator disposed at a first position in a fluid passageway of a pressure regulator and a second noise attenuator disposed at a second position in the fluid passageway. The second position is spaced apart from the first position along the fluid passageway. The example apparatus also includes fasteners extending between the first noise attenuator and the second noise attenuator to position the first noise attenuator at the first position and the second noise attenuator at the second position. The fasteners are to couple to peripheral portions of the noise attenuators.

主权项

1. An apparatus comprising:
a first noise attenuator including an annular ring that couples to a wall of a fluid passageway of a pressure regulator to position the first noise attenuator at a first axial position in the fluid passageway; a second noise attenuator positioned at a second axial position in the fluid passageway, the second axial position spaced apart from the first axial position along the fluid passageway; and fasteners coupling to and extending between the annular ring of the first noise attenuator and a peripheral portion of the second noise attenuator to retain the first noise attenuator at the first axial position and the second noise attenuator at the second axial position.
