The above-mentioned not enough to prior art, the utility model provides a heavy-calibre butterfly valve is used to flue to solve above-mentioned technical problem.
The utility model provides a heavy-calibre butterfly valve is used to flue, include: valve shaft, valve body and valve plate, the sealed installation valve plate in the valve body, the vertical axial of valve plate is passed to the valve shaft, set up netted strengthening rib in the valve plate, netted strengthening rib is including crisscross fixed vertical muscle and horizontal muscle, set up the through-hole on the valve shaft, the horizontal muscle of netted strengthening rib passes the through-hole.
Further, the diameter of the valve shaft is larger than the thickness of the valve plate.
Furthermore, an annular reinforcing rib is welded on the outer periphery of the reticular reinforcing rib.
Further, the annular reinforcing rib penetrates through the valve shaft through the through hole.
Further, the valve plate surface is provided with a void for thermal expansion.
Furthermore, an elastic sealing ring is arranged between the valve plate and the inner wall of the valve body.
The utility model provides a pair of heavy-calibre butterfly valve is used to flue sets up the structural stability of strengthening rib reinforcing valve plate, avoids the valve plate because of the overheated impaired moving down of high temperature flue gas to make the strengthening rib pass the valve shaft, avoid the valve shaft because the influence of valve plate gravity is crooked, improved the life of heavy-calibre butterfly valve is used to the flue.
Furthermore, the utility model relates to a principle is reliable, and simple structure has very extensive application prospect.
