Abstract (en)
[origin: EP2685016A1] The invention relates to a shut-off device (100) especially for sewage drains, characterised in that the device has an inlet fitting piece (4, 167) and a dual valve system (200), the inlet fitting piece (4, 167) comprises a valve seat (10, 178), the first valve of the dual valve system (200) is a clack valve (9, 168) that is rotateably mounted on the inlet fitting piece (4, 167) above the valve seat (10, 178) such that the clack valve (9, 16) rests in an inclined or vertical position against the valve seat (10, 178) in the rest position, the dual valve system (200) further comprises a flexible shut-off valve (11, 169) comprising a flexible material (11 a) having a larger surface than an upper surface (9a) of the clack valve (9), a lower side (11d) of the flexible material (11a) is provided with auxiliary weight (18) and the upper side (11 b) of the flexible material (11 a) is affixed to the inlet fitting piece (4, 167) above the clack valve (9, 168) whereby the lower side (11 d) of the flexible material (11 a) provided with the auxiliary weight (18) hangs down from the clack valve (9, 168) and biases the clack valve (9, 168) towards the rest position. The invention further relates to a drain shaft assembly (300) comprising a drain shaft (302) being in communication with a sewage drain (304) and an upper drain shaft opening (306) being in communication with the outside (308), characterised by comprising a shut-off device (100) according to the invention.
