WATER FLOW DAMPER Russian patent published in 2024 - IPC E02B8/06 

FIELD: pipelines.

SUBSTANCE: invention relates to hydraulic engineering, hydraulics, hydromechanics for water flow damping in end devices of pipelines and tunnel culverts. Water flow energy absorber, including a supply pipe, a conically expanding water conduit, which is located in the well, wherein its upper part on the side of the discharge pipeline is made in the form of an outlet hole coinciding with the bottom of the discharge tray, wherein the well comprises a plurality of vertical walls defining the overall shape of the well in the form of a polyhedron tapering upwards, the inner walls contain fixed tubular elements, mirrored to each other on the side walls of the well, which determine the shape of the well, which is multifaceted, the output upper ends of which are plugged, and the inlet lower ends with inlets are oriented in the direction of the expanding water conduit, the side walls of the polyhedral well in its upper part are connected by a partition made in the form of a grid dividing the damping chamber into two unequal parts, wherein above the lower ends of the tubular elements with inlet holes, the tubular elements are additionally connected to each other by a transverse partition wall also in the form of a grid, above the upper partition in the form of a grid there are perforated pipes with holes, at least two, their free ends are plugged, wherein additional well damping chamber has discharge chute with its bottom communicated with discharge pipeline provided with control valve.

EFFECT: improving high degree of protection of the discharge channel of a consumer from dynamic effects of excess energy of a high-speed flow.
