Corn silo cell gas-tight slide valve plate - has pressure ring and sealing ring pressing against valve and throughflow connection in closed position

摘要

The gastight slide valve is partic. for firm material, such as for corn silo cell to be fumigated. In its housing, a controllable valve plate is locked outwards in the closed position by a movable sealing frame. On the periphery of a through flow connection (1) is a chamber (3), in which a cylindrical pressure ring (4) is controllable in a vertical direction via a fork-shaped two-armed lever. In the closed position, the ring (4) to other with its sealing ring (9) with two seal surfaces (10, 10') is pressable against the through flow connection (1) and the valve plate (6).
