<p>The shut-off valve has a valve housing (1) with two connection openings (2, 3) arranged opposite one another and with two seating surfaces (14), associated with these connection openings (2, 3), in the interior of the valve housing. In the valve housing (1) there is a slide (18), which can be moved transversely with respect to the axes of the connection openings (2, 3) and interacts with both seating surfaces (14), which slide (18) is connected to a valve stem (16). The slide (18) is of conical design in its region (22) which counteracts with the seating surfaces (14), as are the seating surfaces (14) in the valve housing (1), so that the latter - with the valve closed - cover the conical region (22) of the slide (18). The conical shaping of the slide and of the seating surfaces simplifies the manufacture of the valve and at the same time achieves good sealing. <IMAGE></p> |
