Double-cover sealed transferring device with safety interlocking

Abstract

The invention relates to a double-cover sealed transferring device with safety interlocking. The double-cover sealed transferring device comprises a hot chamber sealing door and a transferring bucketwhich comprises a bucket cover and a bucket flange, the hot chamber sealing door comprises a door body, a hot chamber flange and a locking ring, and the door body is matched with the hot chamber flange; in the process when the bucket flange is connected with the hot chamber flange, the hot chamber flange is connected with the bucket cover, and the bucket flange is separated from the bucket cover;in the process when the bucket flange is separated from the hot chamber flange, the hot chamber flange is separated from the bucket cover, and the bucket flange is connected with the bucket cover; after the locking ring rotates to open the door body, an anti-rotating component locks the locking ring. The device has the advantages that transfer of a material between the inside and the outside of box chamber equipment is completed without fouling exposed surface; components like a power element, a sealing ring and the door component can be changed quickly; by adopting the sealing ring which is in a special shape, sealing effect can be ensured, friction force with a metal member is reduced, and the whole device is light and flexible to operate; through a door lock device and a locking device,misoperations in any forms are prevented logically while manual resetting is not needed.

Description

technical field [0001] The invention belongs to the field of nuclear engineering industry, and in particular relates to a double-cover sealed transfer device with safety interlock. Background technique [0002] In the field of nuclear chemical industry, the double-cover sealed transfer device is widely used in the transfer of radioactive and toxic materials between sealed chambers (such as hot chambers, work boxes and glove boxes, etc., hereinafter referred to as chambers) and between radioactive and non-radioactive environments. of transshipment. When the material transfer container is docked with the chamber interface, the double-cover sealed transfer device can ensure that the radioactive atmosphere will not leak to the outside during the material transfer process, and at the same time ensure that the sealing device will not contaminate the chamber and the chamber during the opening and closing process. Any surface other than the inner surface of the transfer container t...

Problems solved by technology

However, in the prior art, in order to ensure sufficient sealing and pressing force, the surface friction between the sealing member and the metal part is relatively large, resulting in a relatively large opening and closing resistance of the airtight door, which is not flexible enough.
