#CMT# #/CMT# The device has a main connection element (3) having upstream and downstream parts (31, 32) with respect to an exhaust valve outlet (1), and a lateral connection element (4) arranged between the outlet and the part (31) and forming an upstream rotular assembly (5) with the part (31). Another lateral connection element (6) is arranged between the part (32) and a pipeline (2) and forms a downstream rotular assembly (7) with the part (32). Central adapter elements have a central element (33) and two intermediary connection elements (34, 35) connecting the element (33) to the parts, respectively. #CMT#USE : #/CMT# Used for connecting an exhaust valve outlet to a pipeline (claimed) that is utilized in atmospheric vent riser e.g. nuclear power station, for releasing high-pressure and high-temperature vapor. #CMT#ADVANTAGE : #/CMT# The upstream and downstream rotular assemblies allow a sufficient angular displacement of the pipeline with respect to the valve outlet, thus providing a flexible connection between the exhaust valve outlet and the pipeline, and hence deadening the force exerted by the pipeline on the valve outlet, and decreasing the moment generated by the pipeline on the valve outlet in order to reduce sealing problems at the level of the exhaust valve outlet after a time of its use and permits to reduce the wear. The central adapter elements permit the device to be adapted to different configurations independent of the distance between the output of the valve outlet and the pipeline and permit to dismount the connection for cleaning the device in an easier manner without dismounting the upstream and downstream assemblies, thus facilitating the maintenance of the device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional schematic view of a rotular connection device. 1 : Exhaust valve outlet 2 : Pipeline 3 : Main connection element 4, 6 : Lateral connection elements 5 : Upstream rotular assembly 7 : Downstream rotular assembly 31 : Upstream part 32 : Downstream part 33 : Central element 34, 35 : Intermediary connection elements. |
