The phase-separating element has a basic body comprising a receiving part (1), a head part (2) and a perforated core pipe (3) arranged between and connecting these two parts. A fibre packing (5) is wound around the core pipe (3) and projects on either side above the perforated region of the core pipe (3). The front face of the packing is in contact with stopping surfaces (8, 9) of the receiving part (1) and the head part (2), and the packing is surrounded by a supporting bandage (6). To prevent the phase mixture from flowing around the fibre packing (5) in the region of its ends, the end regions of the fibrous layer are sealed. This sealing is effected by arranging a conical beaded ring (10, 11) at each end region of the fibre packing (5) between the core pipe (3) and the fibre packing (5). The apexes of the conical sealed rings are located at a distance from the neighbouring stopping surfaces (8, 9). Sealing rings (19, 20) surrounding the fibre packing are also arranged at the ends of the fibre packing and extend axially from the stopping surfaces to approximately the apexes of the beaded rings (10, 11). The sealing rings (19, 20) and beaded rings (10, 11) are dimensioned in relation to the thickness and type of the fibre packing (5) so as to prevent through flow in the event of a maximum permissible pressure difference. |
