Title:
GAS COLLECTING DEVICE FOR ISOTROPIC PRESSURE PRESSURIZING DEVICE AS WELL AS GAS FILLING AND RECOVERING METHOD
Document Type and Number:
Japanese Patent JPH10227573
Kind Code:
A
Abstract:

To enable a further shortening of cycle time of isotropic pressure pressurizing treatment by a method wherein a plurality of gas cylinders are divided into cylinders for supplying gas for filling a pressure difference and cylinders for pressure difference recovering while a compressor for the cylinders for transferring compressed gas forcibly from the recovering cylinder into the supplying cylinder is provided.

A gas collecting device 5 is provided with a supplying gas cylinder 19, supplying pressurized medium gas upon pressurizing a differential pressure, a recovering gas cylinder 20, recovering gas upon differential pressure recovering, and a compressor 21 for cylinders, which transferrs the pressurized medium gas in the gas cylinder 20 for receiving into the gas cylinder 19 for supplying the pressurized medium gas. The supplying gas cylinder 19 and the recovering gas cylinder 20 are constituted of the groups of cylinders consisting of cylinder main bodies 19a-19d and the cylinder main bodies 20a-20d. The suction side of the compressor 21 for cylinders is connected to the cylinder main bodies 20a-20d side of an opening and closing valve 27 for a recovering pipeline 25 while the exhaust side of the same is connected to the cylinder main bodies 20a-20d side of another opening and closing valve 24 for a supplying pipe 22. In this case, the pressurized medium gas is transferred from the recovering gas cylinder 20 into the supplying gas cylinder 19 and, therefore, pressurizing capacity is lower than that of the high-pressure compressor 8.
