Flange shape is consistent and the cover plate that is bolted on the airduct spacer flanger, is provided with central axis on the primary air piping
The import being vertically arranged, the airduct suction flange are connected in the import, are provided with central axis on the primary air piping
Horizontally disposed outlet, the wind tube outlet flange are connected in the outlet, are provided with central axis on the primary air piping
Horizontally disposed and with the primary air piping on export center dead in line interior conduit, one end of the interior conduit and the wind
Pipe spacer flanger and cover plate connection, the other end of the interior conduit are flushed with the outlet of the primary air piping, and its innovative point exists
In：The shoulder hole of central axis and the airduct spacer flanger centerline axis parallel, the rank is provided with the airduct spacer flanger
Terraced hole is divided into macropore and aperture, and the macropore is contacted with the cover plate, and the aperture is away from the cover plate；Arrange in the macropore
Have gap between the macropore of the wear strip being close on the cover plate, the wear strip and the shoulder hole, the inwall of aperture, one
On the inwall of secondary airduct, the outer wall of interior conduit, welding is provided with ceramic paster.
Preferably, the shoulder hole central axis on the airduct spacer flanger and the airduct spacer flanger central shaft
Line overlaps.
Preferably, the angle between the export center axis in the plane and the primary air piping at the cover plate place is
30-40 degree.
Preferably, the angle between the export center axis in plane and the primary air piping that the cover plate is located is 35
Degree.
It is an advantage of the current invention that：By on airduct spacer flanger arrange shoulder hole, and shoulder hole in diameter compared with
Inside of the little hole closer to primary air piping, and wear strip is set in the macropore in shoulder hole, by wear strip and rank
Terraced hole macropore and primary air piping inwall post ceramic paster, by using said structure primary air piping inwall and and airduct
There is no gap in spacer flanger junction, so as to substantially improve its sealing effectiveness.
Description of the drawings
