Further, the height of the bump is equal to the height of the split flange pressing block.
Furthermore, a rubber layer is arranged on the side surface of the lug towards the notch, so that the problem of serious abrasion caused by rigid connection between the two lugs is prevented.
When the device is in specific work,
1. connecting a vacuum flange joint on a vacuum system, wherein the vacuum flange joint is a standard CF50 flange joint;
2. installing two split flange pressing blocks on a vacuum flange joint, wherein the reverse surface of a first block is in contact with the vacuum flange joint, the other split flange pressing block is reversely buckled on the first split flange pressing block, and when the split flange pressing blocks are placed, the threaded holes between the first and second split flange pressing blocks are aligned;
3. the vacuum flange joint and the split flange pressing block are arranged between each other through the fastening screws, and the fastening and sealing effects can be achieved by arranging the vacuum flange joint and the split flange pressing block according to a certain correct sequence.
The utility model discloses following beneficial effect has:
the split flange pressing block of the utility model does not need to install the mounting flange on a vacuum pipeline or a vacuum product in advance, and can be replaced by the flange especially when the existing flange joint is forgotten to be preassembled; meanwhile, the volume of the vacuum product is reduced by the split flange pressing block, so that the vacuum product is more convenient to carry or transport.
