Abstract

Non-returning valveIt includes a substantially tubular base part (2), which is next to the inner wall of a duct (1) and forms a peripheral seat (3) close to said wall, and a flexible sheet (4) that completely covers the hole of the base part (2) when its periphery comes into contact with said peripheral seat (3), and is equipped with coupling resources (6) to said base part (2). Said sheet (4) is articulated so that its periphery (5) can be separated and moved together with respect to said seat (3) letting the liquid pass when the pressures on both sides of the sheet (4) tend to separate the sheet (4) with respect to the seat (3) and preventing passage when said projections tend to push the sheet (4) against the seat (3), causing its periphery to form a closure with said seat (3).It is easy to build and offers a large passing section with a small movement of the closing element.
