Problems solved by technology
The mouth of the furnace tube needs to have a sealing device to ensure that the protective gas does not leak. The existing technology uses a grooved axial rubber ring sealing structure. The furnace tube will be deformed after heating, and the original sealing fit size will change. The sealing structure cannot effectively complete the sealing function after several uses
[0003] Existing sealing structures such as figure 1 As shown, a grooved axial rubber ring sealing structure is adopted. After multiple heat treatments, the thin-walled furnace tube will change, which will reduce the sealing effect.

Embodiment Construction
[0017] Below in conjunction with accompanying drawing, the present invention is further described:
[0018] Such as figure 2 As shown, when working, put the pipe 1 to be processed into the furnace tube 2, and install 5 sealing rubber rings 3 and 4 rubber ring spacers 4 alternately on the sealing mounting seat 7, where multiple sealants are provided. ring, which improves the sealing effect and sealing reliability; install the sealing mounting seat 7 equipped with the sealing rubber ring 3 and the rubber ring spacer 4 into the furnace tube 2 filled with protective gas, and then press the rubber ring 5 and The compression nuts 6 are installed on the sealing mounting seat 7 in sequence, and the sealing rubber ring 3 can be in a compressed state by tightening the compression nuts 6; after the protective gas is passed into the furnace duct through the intake pipe 8, heat treatment is carried out, according to the deformation of the furnace duct According to the situation, the tigh...

The invention belongs to a rubber ring sealing technology, and relates to a rubber ring sealing device capable of adjusting the compression amount. The device comprises a to-be-treated pipe (1), a furnace pipe (2), a sealing rubber ring (3), a rubber ring spacer sleeve (4), a rubber ring pressing ring (5), a compression nut (6), a sealing mounting base (7) and a protective gas inlet pipe (8). Thesealing device is provided with a plurality of seals, so that the sealing reliability is effectively improved. A sealing ring groove structure is omitted, and the processing difficulty is reduced. Even if the furnace pipe has local deformation, the compression amount of the rubber ring can be adjusted through the nut, and the bonding degree of a sealed part is ensured. The sealing structure can effectively improve the sealing effect.
Description
technical field [0001] The invention belongs to rubber ring sealing technology and relates to a rubber ring sealing device with adjustable compression. Background technique [0002] The technical problem to be solved: precision pipes need to be heat treated in a protective atmosphere during the processing process. The specific process of the treatment is to put a certain amount of pipes to be treated into the furnace tube. The furnace tube is a thin tube with one end closed and the other open. Wall pipe, after injecting a certain amount of protective gas into the furnace pipe, put the furnace pipe containing the pipe to be processed into the furnace for heat treatment. The mouth of the furnace tube needs to have a sealing device to ensure that the protective gas does not leak. The existing technology uses a grooved axial rubber ring sealing structure. The furnace tube will be deformed after heating, and the original sealing fit size will change. After several times of use, ...
