In lower groove, the inner end of lower lug is connect by lower adjusting screw with lower groove inner wall.
Further, the lower surface of upper lug outer end is equipped with upper counterbore, and screwing is inserted into counterbore；Lower lug outer end
Upper surface be equipped with lower counterbore, lower screw is inserted into lower counterbore.
Further, upper lug and lower lug are L shape blocks.
Further, there are upper gaps between the medial surface of upper lug and the lateral surface of superior hemiseptum；The inside of lower lug
There are lower gaps between face and the lateral surface of lower semi-diaphragm.
The beneficial effects of the present invention are: the present invention is kept away instead of the conventional baffle supporting structure using gasket or cushion block
Exempt from the work such as repeated measurement and match grinding when installation, improves operability when installation.It is traditional that the present invention realizes substitution
The partition supporting structure of gasket or cushion block, the work such as repeated measurement and match grinding, improve steam turbine general-assembling when avoiding installation
When operability.
