ABSTRACT:
A vacuum-tight coat of the cryostat encloses a thermally insulated vessel, intended to keep cryogenic products, so that between the surfaces of said elements there is a heat-insulating cavity from which air is evacuated. In order to build up vacuum in the cavity a vacuum valve on the vacuum-tight coat is provided. Between the inlet opening of the vacuum valve and the thermally insulated vessel, there is disposed a cup which is fixed rigidly in the heat insulating cavity. The cup has perforations evenly distributed on its lateral surfaces.
The heat-insulating cavity of the proposed cryostat, having the capacity of 47 liters, should be evacuated for 7 days at the capacity of the evacuating system of 200 liters (at STP) per hour. In other words, owing to the special design of the vacuum valve, the evacuation of the heat-insulating cavity of the cryostat is effected in accordance with the capacity of the evacuation system, and the vacuum-multilayer insulation remains intact during this process.
