Description

TECHNICAL FIELD The present invention relates to a high-pressure container device, and is used for a gas pressure impregnation device, a hot isostatic pressurizing device, a cold hydrostatic pressurizing device, and the like.

(Prior Art) In a high-pressure container device, the upper and lower openings of a cylindrical high-pressure container must be sealed with an upper lid and a lower lid, and at the same time, the axial force due to the internal pressure of the container must be carried.

Therefore, with a model that attaches the upper lid and the lower lid with a screw structure,
There is a type in which an upper lid and a lower lid are fitted with each other via an airtight seal, and a supporting frame engaging with the lid carries an axial force. From the viewpoint of productivity and safety, there is a supporting frame rather than a screw structure. The type is advantageous.

However, in the support frame type, a member protruding outward in the axial direction at the axial center portion of the container, for example, a push rod for inserting and removing the product,
It was difficult to provide a cylinder for opening and closing the lid.

In view of this, in Japanese Utility Model Publication No. 62-3676, a support frame that carries an axial force is composed of a divided body of a first support frame and a second support frame, and each of the first and second support frames has an upper and lower lid.
