Abstract
A cooling system for the hot isostatic pressurizing equipment which is provided with valves and actuators at the lower part of the equipment so that they are not subject to thermal deformation. The valves and actuators are installed independently from each other so as to eliminate a need for increasing the diameter of the vessel. The valve is attached to a lower vent hole formed in the radial direction in the supporting cylinder installed on the inner bottom closure. The valve is energized in its closing direction by a spring and is operated by the actuator installed on the outer bottom closure detachable from the inner bottom closure.
