Abstract
Provided is a flue baffle. The flue baffle comprises a shell body, a valve plate, a shaft and a transmission device. An inner cavity of the shell body is in a cylindrical shape, coupled holes are formed in the shell body, and the coupled holes are symmetrical about a diameter in a cylindrical shape. The shaft penetrates inside the coupled holes. The valve plate is in a circular shape and the part of the shaft in an inner chamber is connected with the valve plate which is provided with a reinforcing rib. The reinforcing rib is perpendicular to the surface of the valve plate and the shaft penetrates through a plane on which the reinforcing rib is placed. Any end of the shaft is connected with the transmission device. The valve plate becomes thinner because of corrosion; particularly a connecting position between the valve plate and the shaft bears large force. After the reinforcing rib is used, the valve plate bears even force and the service life is prolonged, and meanwhile, the deformation of the valve plate is reduced.
Description
Technical field
The technical program belongs to boiler technology field, specifically a kind of damper of anti-flue gas corrosion.
Background technology
Damper is the valve that is applied to the adjust flux on the flue of the industries such as petrochemical industry, metallurgy, chemical industry, the most sulfur-bearing of industrial furnace flue gas has corrosivity, and this just needs valve and have under corrosion condition with the frequent contact component of flue gas that can be arranged service life better.
The valve plate of traditional damper is all metal (for example carbon steel or stainless steel) sheet material processing welding production, during work temperature distortion large, poor reliability, service life is not long.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the technical program proposes a kind of damper of anti-flue gas corrosion, and concrete technical scheme is as follows:
A kind of damper comprises housing, valve plate, axle and transmission device.The inner chamber of described housing is cylindrical shape, is split into right hole on housing, and paired hole is about columnar diameter symmetry, and described axle is through this in the hole; Valve plate is circular, and axle is at housing inner chamber part connection valve plate; Valve plate is provided with reinforcement, and reinforcement is perpendicular to the valve plate surface, and axle passes plane, reinforcement place; Arbitrary end connection for transmission device of described axle.Due to corrosion, the junction of valve plate meeting attenuation, especially valve plate and axle is stressed larger, after using reinforcement, can make the stressed even of valve plate, increases the service life.Simultaneously, also reduced the deformation of valve plate.
Be connected with Sealing shield ring on the wall of the chamber of housing inner chamber, the position the when axis of the position of Sealing shield ring and described valve plate plane and housing inner chamber is vertical is corresponding, and the height of Sealing shield ring is poor greater than the diameter of housing inner chamber and valve plate.The chamber wall of described housing inner chamber is provided with the insulating lining layer.
Described transmission device is flange or shaft coupling.
Described paired hole has a pair of, and described axle is to there being one, and valve plate is overall structure, and axle is connected on the diameter of valve plate.
Described paired hole is comprised of polylith independence sheet material many, valve plate, axle many; The quantity of described axle is identical with the logarithm in hole, and the quantity of the sheet material of composition valve plate is identical with the quantity of axle; Described each root axle is parallel.The quantity of axle is determined by the diameter in cigarette air channel.
Described valve plate is the spheroidal graphite cast-iron plate.The spheroidal graphite cast-iron plate has excellent decay resistance.
Described reinforcement has a plurality of, and each reinforcement is parallel to each other, and is evenly distributed along the axis of axle.
The technical program has extended service life greatly, has a cost lower, easy to make, simple in structure, the advantage of long service life.
Description of drawings
Fig. 1 is the structural representation of the present embodiment;
Fig. 2 is the cross-sectional schematic of shell structure;
In figure, baffle plate housing (containing flange) 1, bearing 2, axle 3, valve plate 4, Sealing shield ring 5, sleeve pipe 6, reinforcement 7, insulating lining 8, flange 9, rotating shaft driving mechanism 10.
The specific embodiment
The technical program is further illustrated as follows below in conjunction with accompanying drawing and the specific embodiment:
A kind of damper comprises housing, valve plate, axle and transmission device.The inner chamber of described housing is cylindrical shape, is split into right hole on housing, and paired hole is about columnar diameter symmetry, and described axle is through this in the hole; Valve plate is circular, and axle is at housing inner chamber part connection valve plate; Valve plate is provided with reinforcement, and reinforcement is perpendicular to the valve plate surface, and axle passes plane, reinforcement place; Arbitrary end connection for transmission device of described axle.
In this example, because the solderability of cast iron is poor, hole on cast iron valve plate, be connected on axle by overlapping effective bolt.
Be connected with Sealing shield ring on the wall of the chamber of housing inner chamber, the position the when axis of the position of Sealing shield ring and described valve plate plane and housing inner chamber is vertical is corresponding, and the height of Sealing shield ring is poor greater than the diameter of housing inner chamber and valve plate.The chamber wall of described housing inner chamber is provided with the insulating lining layer.
In this example, described transmission device is flange; Described paired hole has a pair of, and described axle is to there being one, and valve plate is overall structure, and axle is connected on the diameter of valve plate.Described valve plate is the spheroidal graphite cast-iron plate.Described reinforcement has 3, and each reinforcement is parallel to each other, and is evenly distributed along the axis of axle.
