Abstract
Example noise attenuators for use with process control devices are described herein. An example apparatus includes a first plate and a second plate disposed in a fluid passageway of a noise attenuator. The second plate is spaced apart from the first plate. The example apparatus also includes a first support rod extending along a central axis of the fluid passageway. The first support rod is coupled to the first plate and to the second plate. The example apparatus further includes a second support rod extending along an axis parallel to and offset from the central axis. The second support rod is coupled to the first plate and the second plate.
Claims20
An apparatus comprising:
- a first plate, a second plate, and a third plate disposed in a fluid passageway of a noise attenuator, the second plate spaced apart from and between the first plate and the third plate;
- a first support rod coaxial to a central axis of the fluid passageway, the first support rod coupled to the first plate and to the second plate;
- a second support rod extending along an axis parallel to and offset from the central axis, the second support rod coupled to the first plate and the second plate;
- and
- a third support rod extending along an axis parallel to and offset from the central axis, the third support rod coupled to the second plate and the third plate and not the first plate.
An apparatus comprising:
- a first plate, a second plate and a third plate spaced apart from each other in a fluid passageway of a noise attenuator;
- a first set of support rods coupled between the first plate and the second plate;
- and
- a second set of support rods coupled between the second plate and the third plate and not the first plate, the support rods of the second set aligned along respective axes offset from the support rods of the first set.
An apparatus comprising:
- a first plate, a second plate, and a third plate disposed in a fluid passageway of a noise attenuator, the second plate spaced apart from and between the first plate and the third plate;
- a first support rod extending through centers of the first and second plates, the first and second plates coupled to the first support rod;
- a second support rod coupled to peripheral portions of the first and second plates, the second support rod parallel to and spaced apart from the first support rod;
- and
- a third support rod coupled to peripheral portions of the second and third plates and not the first plate, the third support rod parallel to and spaced apart from the first support rod.
