    • 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.
    • 在用于高压蒸笼的压力密封装置中,密封辊在安装在纤维制品上的辊密封机构中形成辊隙,进料和取出高压蒸笼容器体的开口。 当纤维制品进入或取出时,辊密封机构将容器的内部屏蔽外部空气,并且位于纤维产品通道所延伸的密封块的上平面上。 在形成密封机构时可以将不同的构件与密封辊组合,例如形成为可渗透软管的中间辊插入设置在通过密封块的纤维产品通道的相对侧上的凹部中。 在另一个实施例中,弹性密封构件被放置成与密封块和密封辊接触。 在另一个实施例中,在纤维产品通道的一端设有屏蔽阀,用于调节容器的内部压力并防止突然的压力泄漏。 作为另一替代方案,可以使用容器内部压力检测器和压力提供力调节机构,或者可以使用精密调节机构来进行密封块的上下运动,以将密封辊和中间辊的压力接触力稳定到 适当的价值。
