LIQUID PRESSURIZATION PROCESSING TREATMENT APPARATUS AND LIQUID PRESSURIZATION PROCESSING TREATMENT METHOD

To provide a liquid pressurization processing treatment apparatus capable of integration, downsizing and enhancement in safety of the apparatus, and suppressing pressure liquid from remaining around a work-piece when the work-piece is taken out, so as to reduce a risk of leakage of the pressure liquid by limiting an area where high pressure is applied during pressurization to a pressurizing processing section as much as possible.SOLUTION: A liquid pressurization processing treatment apparatus comprises: a first flow path 07 provided above a mounting base 03 and having an opening at an uppermost part of an inner side face, and a second flow path 06 having an opening at a lowermost part of the inner side face; a pressure vessel 02 having a shape with an inner upper face inclined with respect to a vertical direction with an opening side of the first flow path 07 as the uppermost part; an on-off valve 20 connected to the second flow path 06 and an on-off valve 30 connected to the first flow path 07 mounted on an outer side face of the pressure vessel 02; and a pressurizing mechanism 10 disposed passing through the inner upper face of the pressure vessel 02 and fitted with the pressure vessel 02 and the mounting base 03, and reducing a volume of a closed space formed when the on-off valves 20 and 30 are closed so as to pressurize the inside of the closed space.SELECTED DRAWING: Figure 1 【課題】 加圧時に高圧となる領域を加圧加工処理部に極力限定して、装置の一体化、小型化と安全性向上を可能とし、被加工物を取出す際に被加工物の周囲に加圧液が残留することを抑制し、加圧液の漏洩リスクを低減できる液体加圧加工処理装置を提供する。【解決手段】 載置ベース０３の上方に設けられ内部側面の最上部に開口部を有する第一の流路０７と内部側面の最下部に開口部を有する第二の流路０６とを備え内部上面が第一の流路０７の開口部側を最上部として鉛直方向に対して傾斜した形状の圧力容器０２と、圧力容器０２の外部側面に装着され第二の流路０６に接続された開閉弁２０及び第一の流路０７に接続された開閉弁３０と、圧力容器０２の内部上面を貫通して設けられ圧力容器０２と載置ベース０３とが嵌合され開閉弁２０，３０が閉じられたときに形成される閉鎖空間の容積を減少させて閉鎖空間内を加圧する加圧機構１０と、を有するものとする。【選択図】図１
