ABSTRACT:
In a pressure seal apparatus for a high pressure steamer, seal rolls form a nip in a roll seal mechanism mounted on the fiber products feed in and take out openings of a high pressure steamer vessel body. The roll seal mechanisms shield the inside of the vessel from external air when fiber products are fed in or taken out and are positioned on the upper planes of a seal block through which a fiber products passage extends. Different members can be combined with the seal rolls in forming the seal mechanism, such as intermediate rolls formed as water permeable hoses are inserted into concave parts provided on opposite sides of the fiber products passage through the seal block. In another embodiment an elastic sealing member is placed in contact with the seal block and the seal rolls. In still another embodiment a shielding valve is provided at one end of the fiber products passage for regulating vessel internal pressure and preventing sudden pressure leakage. As another alternative a vessel internal pressure detector and a pressure affording force regulating mechanism can be used or a fine adjustment mechanism can be employed for up and down movement of the seal block for stabilizing the pressure contacting force of the seal rolls and intermediate rolls to an appropriate value.
