Document Type and Number:

WIPO Patent Application WO/2005/071299

Kind Code:

A1

Abstract:

A vacuum heat insulation valve that can be used in high-temperature conditions in a gas supply system and gas discharge system and that can be drastically reduced in size and made compact because of excellent heat insulating performance of the valve. A vacuum heat insulation valve constructed from a valve that has a valve body and an actuator and from a vacuum insulation box that receives the valve. The vacuum heat insulation box (S) is constructed from a rectangular lower vacuum jacket (S₅) that has on its side face a tubular vacuum insulation piping receiving section (J) and whose upper face is opened, and from a rectangular upper vacuum jacket (S₄) that is air-tightly fitted to the lower vacuum jacket (S₅) from the above and whose lower face is opened.
