| 摘要 |
The present invention relates to a fitting arrangement (1) for a cask (13), comprising a fitting sleeve (2) having a resiliently relatively moveable riser pipe (6) arranged therein, wherein the fitting sleeve (2) comprises an inner, conically-extending sealing surface (17) tapering towards an upper end (5), and a seal (4) is incorporated between the inner sealing surface (17) and the upper end (5) of the riser pipe (6), and due to a spring force the riser pipe (6) is pressed with the seal (4) against the sealing surface (17), and the seal (4) is arranged internally in the upper end (5) of the riser pipe (6), wherein a sealing body (7) is resiliently relatively moveably arranged in the upper end (5) of the riser pipe (6), which sealing body comes into contact in an interlocking manner with an inner sealing surface (16) of the seal (4) due to a spring force, and the seal (4) has an inner reinforcement ring (19) which is surrounded by an elastic sealing material (20), which is characterised in that the reinforcement ring (19) has a material recess (21) on the outer sleeve surface (31) thereof, such that the distance (22) from reinforcement ring (19) to the inner sealing surface (17) of the fitting sleeve (2) is increased, so that in the event of a defined overpressure, same can be detached from the gas side (14) in a controlled manner via the elastically deforming sealing material (20). |
