Shut-off valve, composed of a container ( 3 ) provided with valve seat ( 4 ), and also a valve body ( 2, 22, 42 ) that can be moved through the opening bounded by the valve seat ( 4 ), in order to provide a seal. The valve body ( 2, 22, 42 ) is provided with a conical or spherical shut-off edge and is connected to the container ( 3 ) by way of a flexible connecting part ( 5 ). This makes it possible to move the valve body ( 2, 22, 42 ) laterally, in other words perpendicular to the direction of closing, and in this way achieve an opening of the shut-off valve. The container ( 3 ) can comprise any construction known in the prior art. |
