| 摘要 |
<p>The invention relates to a rotular connection device for pipelines, especially for a pipeline located at the outlet of exhaust valves for releasing high-pressure and high-temperature vapour. Said device is especially used in atmospheric vent risers, for example in nuclear power stations. The inventive device comprises a main connection element (3) provided with an upstream part (31) and a downstream part (32) in relation to the exhaust, a first lateral connection element (4) which is arranged between the exhaust (1) valve outlet and the upstream part (31) of the main connection element (3), forming an upstream rotular assembly (5) with the upstream part (31), and a second lateral connection element (6) which is arranged between the downstream part (32) of the main connection element (3) and the pipeline (2), forming a downstream rotular assembly (7) with the downstream part (32) of the main connection element (3). Characteristically, the main connection element (3) comprises a central adapter element (33, 34, 35) between the upstream (31) and downstream (32) parts.</p> |
