Sound treatment assembly for a fluid transmission line

摘要

A sound treatment assembly includes an outlet member having a bore extending along a longitudinal axis, and a first flange portion is adapted to be coupled to portion of a valve body of a regulator valve. The first flange portion includes a contoured mating surface adapted to mate with a corresponding contoured portion of an exterior surface of the valve body. The outlet member also includes a second flange portion disposed at the second end. A diffuser assembly includes diffuser housing extending along the longitudinal axis, and a first flange portion is disposed at the first end of the diffuser housing and is adjacent to the second flange portion of the outlet member. One or more diffuser elements are disposed within an interior of the diffuser housing to reduce noise levels in the fluid exiting the outlet member.

主权项

1. A sound treatment assembly for use in a fluid transmission line, the sound treatment assembly comprising:
an outlet member extending along a longitudinal axis from an open first end to a longitudinally opposite open second end, and an outlet bore extending from the first end to the second end, the outlet member having a first flange portion disposed at the first end, the first flange portion being adapted to be coupled to portion of a valve body of a regulator valve, wherein the first flange portion includes a contoured mating surface adapted to mate with a corresponding contoured portion of an exterior surface of the valve body, the outlet member having a second flange portion disposed at the second end; a diffuser assembly comprising: a diffuser housing coupled to and not integrally formed with the outlet member, the diffuser housing extending along a longitudinal axis from an open first end to a longitudinally opposite open second end, the diffuser housing having a bore extending from the first end to the second end, the bore including a first portion that extends from a first end to a second end, wherein the first portion diverges from the first end to the second end; a first flange portion disposed at the first end of the diffuser housing, the first flange portion disposed adjacent to the second flange portion of the outlet member; a second flange portion disposed at the second end of the diffuser housing, the second flange portion adapted to be coupled to portion of a downstream pipe; and one or more diffuser elements disposed within the bore.
