PROBLEM TO BE SOLVED: To provide a high-pressure treating device for expandables packed with soft packages. SOLUTION: A device equipped with a tubular vessel 1 has a sealing unit 2 equipped with assemblies 8 at respective distal ends. The assemblies can be moved vertically to an axis Δ of the vessel. The movable assembly 8 has a plug 11 equipped with a packing 17, a spacer 12 with a pulling bar 13, a sliding valve 14 and main body 15 of a sealing unit. The movable assembly 8 is mounted in such a way to slide with a stress recovering mechanism 9. By movement of the sliding valve in the lateral direction together with cooperation of an inclined slope 20 supported on the plug 11 and an assisting channel of the sliding valve 14, the plug in the axial direction can be moved. |
