Abstract
The utility model provides a wear-resistant slag butterfly valve, including a valve, a valve base, a valve axle, a butterfly plate and other parts. The valve base is integrated with the valve. The utility model is characterized in that: the sealed face between the valve base and the butterfly plate is a conical scarf and the cone angle is Beta; the angle between the centerline of the cone and the center of the pipeline is Gamma; and the angle between the plane of the butterfly plate in closed position and the centerline of the valve is Alpha. The beneficial effects of the utility model are large combined surface between the valve base and the valve, good elasticity, good wear resistance of the valve, long service life and reliable two-way sealing.
Description
Affiliated technical field
The utility model relates to the butterfly valve of a kind of metallurgy industry blast furnace granulated slag system, belongs to a kind of valving.
Background technique
Use at present the butterfly valve in metallurgy industry blast furnace granulated slag system, line type structure in adopting mostly is owing to contain impurity such as grain slag in the medium, washing away butterfly plate and valve seat during its flow at high speed, cause the butterfly plate serious wear, easily leak, generally have only about a week its working life.
Summary of the invention
Not wear-resistant in order to overcome the butterfly valve that has the grain slag system now, the deficiency that working life is short, the utility model provides a kind of wear-resisting grain slag butterfly valve, sealing surface adopts the cone scarf, butterfly plate is an ellipsoidal structure, and surperficial spraying plating one deck cemented carbide, more can adapt in the grain slag system and use.
The technological scheme that its technical problem that solves the utility model adopts is a kind of wear-resisting grain slag butterfly valve, is made up of parts such as valve body, valve seat, valve shaft, butterfly plates, and valve seat and valve body are bonded as one, valve seat adopts abrasive rubber, in the middle of the outside of valve seat bulge loop is arranged, big with the adhesive surface of valve body, good springiness.The sealing surface of valve seat and butterfly plate is a cone scarf, cone angle is β, the center line of cone and pipeline center biasing γ angle, butterfly plate is oval, and surperficial spraying plating one deck cemented carbide, butterfly plate is its plane and valve body centerline offset α angle when closed position, has both had eccentric-butterfly-valve one moving advantage of promptly throwing off, and has the advantage of center line formula butterfly valve two way sealed again.
The beneficial effects of the utility model are that valve seat and valve body junction plane are big, good springiness, and the valve overall wear resistance can be good, long service life, and can realize reliable two way sealed.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is embodiment's a tectonic maps;
Among the figure: 1. valve body; 2. valve seat; 3. butterfly plate; 4. valve shaft.
As shown in Figure 1, valve seat (2) is bonded as one with valve body (1), there is bulge loop the centre of valve seat (2), has increased the junction plane with valve body, and valve seat (2) is the cone scarf with the sealing surface of butterfly plate (3), cone angle is β, the center line of cone and pipeline center biasing γ angle, butterfly plate (3) is oval, and surperficial spraying plating one deck cemented carbide, butterfly plate (3) is its plane and valve body centerline offset α angle when closed position, has eccentric-butterfly-valve one moving advantage of promptly throwing off.During action, valve shaft (4) drives butterfly plate (3) rotation, counterclockwise for opening, clockwise for closing.
Claims (3)
1, a kind of wear-resisting grain slag butterfly valve, form by parts such as valve body, valve seat, valve shaft, butterfly plates, valve seat and valve body are bonded as one, it is characterized in that: the sealing surface of valve seat and butterfly plate is a cone scarf, cone angle is β, the center line of cone and pipeline center biasing γ angle, butterfly plate is its plane and valve body centerline offset α angle when closed position.
2, wear-resisting grain slag butterfly valve according to claim 1 is characterized in that: valve seat is a bulge loop in the middle of the outside;
3, wear-resisting grain slag butterfly valve according to claim 1 and 2 is characterized in that: butterfly plate is ellipse, its surperficial spraying plating one deck cemented carbide.
