ACOUSTIC ELBOW FOR FLUID TRANSPORT PIPELINES |
摘要 |
Acoustic elbow for fluid transport pipelines in buildings and networks, comprising an upstream socket, a downstream socket, and an opening closed by a plug. A flexible impact piece is inserted in the opening forming the inner complementary surface of the elbow, the impact piece being adapted to abut against a stop projecting from the upstream socket and/or the downstream socket towards the opening, the impact piece comprising a radial curvature in a radial direction and a longitudinal curvature in the longitudinal direction such that an internal surface of the impact piece comes into register with an internal surface of the upstream socket and/or the downstream socket, respectively.
