DICHTUNGSVENTIL FUER BEHAELTEROEFFNUNGEN

摘要

The invention concerns a sealing valve for apertures in containers, the valve comprising a cover element and, running round the edge of the cover element and integral with it, a wall element. In one application of the valve as a gas-release valve for accumulators, the valve (20) is shaped like a cap and has a beading (24) with a sharply projecting sealing edge running round the inside of the cap wall. On the inside of the cap are control channels (25, 25', 25'') which extend from the top of the cap to the beading (24) and allow the pressure at which gas is released from the accumulator to be set within a given range.
