Description

Technical Field

[0001] The utility model relates to a soft connection suitable for a gas turbine auxiliary machine system. Background Art

[0002] The soft connection structures of existing gas turbine auxiliary systems are similar, and the structures can meet basic needs, but the adjustment amount that can be achieved in a limited space is limited, resulting in the performance of the soft connection being constrained by the space and unable to achieve a better working state. The utility model adopts a soft connection with a new structure, which can further increase the adjustment amount of the soft connection of the gas turbine auxiliary system in a limited space. Summary of the invention

[0003] The utility model aims to provide a soft connection for a gas turbine auxiliary system.

[0004] The above-mentioned purpose is achieved by the following technical solution: The utility model provides a novel gas turbine auxiliary system flexible connection, which comprises: an upper flange (1), a lower flange (2), a sound insulation board (3), a blocking plate (4), a cotton stopper (5), an L-shaped cotton stopper (6), a skin (7), a screw fixing assembly (8), sound absorbing cotton (9) and a bolt group (10), and has the advantages of large adjustment range and good sound insulation performance.

[0005] A novel gas turbine auxiliary system flexible connection is disclosed, wherein a blocking plate (4) is welded to an upper flange (1) and a lower flange (2), a sound insulation plate (3) and a cotton stopper (5) are welded to the upper flange (1), an L-shaped cotton stopper (6) is placed at the cotton stopper (5) when the upper flange (1) and the lower flange (2) are installed, and sound-absorbing cotton is filled between the skin (7) and the cotton stopper (5) and the L-shaped cotton stopper (6), so as to absorb part of the noise.

[0006] In the novel gas turbine auxiliary system flexible connection, the upper flange (1) and the lower flange (2) are connected and fixed using a screw fixing assembly (8) when they are assembled and installed, thereby ensuring that the flexible connection remains fixed when not in use.

[0007] In the novel gas turbine auxiliary system flexible connection, when the upper flange (1) and the lower flange (2) are assembled and installed, the cotton stopper (5) and the L-shaped cotton stopper (6) are in contact and pressed against each other, thereby preventing the sound-absorbing cotton from moving out in the working state.
