Valve for steel hollow body telescoped by being filled with building material

摘要

The closure component (9) has several limitedly radially movable, triangular sealing lips (12) which form a sealing cone (11) with its conical point (13) directed towards the inner space (6) of the hollow body (GST). The sealing lips, on account of their inherent elasticity and tension can be set back into the closure position forming the sealing cone. The basic edges (14) of the lips are at least indirectly position-orientated to the housing in the form of a casing (3) and their side edges running to the cone point are in contact. The basic edges of the sealing lips are fixed to a pipe piece (10) fixed in the casing. The cone point is located inside the casing.
