Abstract

1. Shut-off wedge (1), which can be inserted into a shut-off slide valve, has in plan view an elongated, in particular oval external contour, is arranged transverse to the direction of flow in the slide valve casing, can be displaced by an actuating spindle of the shut-off slide valve in the longitudinal direction of the spindle from the open position into the closed position, and is formed by a rough cast-iron body (3) and a rubber-elastic covering (4) applied thereto, the sealing portions (5, 7) of which, in the closed position of the slide valve, lie elastically against the seating surfaces of the slide valve casing, and which, in the region of its narrow sides, has in each case two guide portions (8) which are provided on the shut-off wedge on opposite sides of the shut-off wedge (1) running in the longitudinal direction of the spindle and are supported against reversed guide portions in the slide valve casing, characterized in that sliding plates (10) prefabricated from a plastic with good sliding properties, high wear resistance and sufficient heat resistance, preferably from polyamide, are seated in the region of the guide portions (8) of the shut-off wedge (1) before the rubber-elastic covering (4) is injection-moulded onto the shut-off wedge (1), the sliding plates being anchored securely to the shut-off wedge (1) during the injection moulding process by rear injection moulding with the injection-moulding compound of the rubber-elastic covering (4).
