Detailed description of the invention
For making the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and tool
Body embodiment is described in detail.
For solving the technical problem of engine exhaust flange switching inconvenience in prior art, the invention provides a kind of aerofluxus
Flange switching device, can realize gas extraction system Fast Installation on assembly line, and can avoid the change of engine exhaust flange,
Reduce development cost.
For realizing above-mentioned functions, as shown in Figure 1 to Figure 3, the technical scheme that the present embodiment provides is:
A kind of exhaust flange switching device 1, including centrally disposed conduit through bore 11 and around conduit through bore 11
Multiple switching installing holes 12 and multiple switching bolt 13；During installation, exhaust flange switching device 1 is positioned at engine exhaust port and row
Between trachea, engine exhaust port realizes connecting by conduit through bore 11 with exhaustor；Conduit through bore 11 two ends are respectively used to solid
Surely connecting engine exhaust flange end 2 and gas exhaust tube flange 3, one of engine exhaust flange end 2 and gas exhaust tube flange 3 pass through method
Blue bolt coordinates with switching installing hole 12 and achieves a fixed connection, and another passes through flange mounting hole and coordinates realization with bolt 13 of transferring
Fixing.
As preferred embodiment, switching installing hole and switching bolt are uniformly distributed around conduit through bore respectively, described
Switching installing hole and switching bolt may be configured as equal amount and be distributed around described conduit through bore interleaved；The present embodiment
In, as it is shown in figure 1, switching installing hole 12 and switching bolt 13 are three, in interleaved on the circle of conduit through bore 11
Arrange.
As specific embodiment, in the present embodiment, as shown in Figures 2 and 3, engine exhaust flange end 2 has
Flange bolt 21, switching installing hole 12 and flange bolt 21 cooperate setting, and the side of exhaust flange switching device 1 (is i.e. managed
Road through hole 11 one end) it is fixed on engine exhaust flange end 2 by switching installing hole 12 and flange bolt 21；Gas exhaust tube flange
Having flange mounting hole 31 on 3, switching bolt 13 and flange mounting hole 31 cooperate setting, and gas exhaust tube flange 3 passes through flange
