发明名称 METHOD FOR INCREASING PRESSURE OF HIGH PRESSURE CONTAINER
摘要 PURPOSE:To safely increase the pressure in a high pressure container, by a method wherein the high pressure container having an up-and-down movable lid of which the upper part has a pressure receiving area larger than that of the lower part is submerged in a liquid and liquid pressure changing corresponding to the depth of the liquid is acted on the lid to utilize pressure due to the difference between the pressure receiving areas of the upper and lower parts of the lid. CONSTITUTION:A high pressure treating body 10 is received in a container 21 and a pressure medium 50 is allowed to fill the container 21 and the space between the upper part of a container main body 20 and the under surface of a lid 40 is filled with a pressure medium 51. Then, the lid 40 of which the upper part has a pressure receiving area larger than that of the lower part is engaged with the opening part of the container 10. Subsequently, the high pressure container 1 is fallen into sea water by a lifting and falling apparatus 60 to start pressurization. The lid 40 moves to the side of the interior of the container by this pressurization to raise the pressure in the container 21 and stops at a position where the axial tension of the upper surface of the lid and that of the upper surface are well-balanced. At this time, the pressure P2 in the under surface side of the lid comes to formula [wherein D1 and P1 are respectively the diameter and pressure of the upper surface of the lid 40, D2 and P2 are respectively the diameter and pressure of the under surface of the lid 40 and H is the depth (m) of water] and is obtained in the container 21.
