Abstract
Provided is a cone-shaped flange piece for boiler chimney connection. An existing face flange is changed into the cone-shaped flange piece so as to avoid the fact that service life of a chimney is shortened due to corrosion caused by accumulated rainwater on the flange piece when it rains. Owning to a slope on the face of the cone-shaped flange piece, the rainwater can flow down smoothly and not stay on the face of the flange piece. Therefore, degree of corrosion at contact points of the flange piece and the chimney can be reduced, and service life of the chimney is prolonged.
Description
Technical field the utility model relates to a kind of improvement of boiler chimney adpting flange sheet, the cone-shaped flange sheet that particularly a kind of boiler chimney connects.
Big of the present known boiler chimney of background technology is arranged on outdoor, particularly the connection of boiler chimney all be on the chimney or under be welded with the face-flange sheet, then flange plate is given fasteningly with screw rod, and be provided with backguy, in case wind-force wallowing motion when strong.But when rainy, the face-flange sheet stops rainwater easily, has strengthened the degree of rusting of chimney and flange plate pad, particularly boiler chimney, not only will take the well cabinet frame when exchanging for owing to height problem, employs crane even, causes certain difficulty for the replacing of chimney.
The purpose of utility model content the utility model provides a kind of boiler chimney that delays the chimney corrosion degree and connects the cone-shaped flange sheet.
The purpose of the utility model is achieved in that the upper flange sheet and the lower flange sheet that are welded on the chimney are tapered; The screw rod installing hole that the upper flange sheet is connected with the lower flange sheet is provided with angle.
Owing to adopt such scheme, solved existing face-flange sheet in the problem that the rainy day rainwater stops, can reduce the corrosion rate of pad, prolonged the service life of chimney.
