Anti-odour sleeve for the end of a liquid discharge pipe and associated installation

摘要

The sleeve has a deformable membrane (1) provided with a valve (2) and a suction eye (3), where the valve and the suction eye are arranged such that the pressure of the liquid is exerted on a face (4a) of the membrane that allows opening of the suction eye while keeping the valve in a closed position. The valve is opened under the action of the liquid pressure exerted on another face of the membrane, where the faces are arranged opposite to each other. The membrane defines two regions arranged on two sides of the membrane. The membrane comprises an S-shape or reversed S projection (9). An independent claim is also included for a liquid discharge installation.
