PURPOSE:To so constitute the title equipment that a heat deformation of a pressure chamber can be controlled, a favorable sealing effect is obtained and high-pressure processing can be performed continuously at high pressure, by forming a heat insulation layer on the inside of a housing forming the pressure chamber. CONSTITUTION:A heat insulation layer 11 is formed on the inside of a housing 8 forming a pressure chamber 4. The heat insulation layer 11 is composed of a heat insulation material such as polytetraethylene fluoride or polyimide or lumber. With this construction, the pressure chamber 4 and housing 8 are isolated from each other thermally and mutual heat conduction is controlled. Therefore, even if a high-temperature pressurizing fluid 6 is supplied to the pressure chamber 4 and the pressure chamber 4 turns high-temperature, the housing 8 is kept at a comparatively low temperature. Then a temperature difference between a temperature of a stationary frame 10 and that of the housing 8 is kept at a low value. With this construction, a heat deformation based on the temperature difference can be controlled. Consequently, a sealing effect of a sealing part 5 can be kept favorable and a useless outflow of the sealing fluid 7 can be prevented. |
