The device in order to ensure, by allowing the hydraulic circuit, the cleaning of a pipe for transporting the effluent

摘要

The device has a float (7) movably mounted on an upstream part of a closure plate, of an effluent transport pipeline, with respect to an effluent flow direction to float and sink during the respective ascending and descending movements of the float. A connection system, arranged between the float and a valve (19), allows the ascending and descending movements for closing and opening a drainage passage arranged in the plate, by the valve. Stop units (16) stops the float at a high level at the end of the ascending movement.
