Abstract
The utility model provides a sealing structure of furnace top diffuse valve used for blast furnace arch system in the metallurgy industry, comprising a valve body, a valve cover and a rubber sealing ring; the rubber sealing ring is arranged at the end surface of the inner side of the valve body; the inner part of the valve cover is also equipped with a seal plate; the seal plate is assembled and welded with valve cover. The beneficial effect of the utility model is that the contact between the valve cover and the rubber sealing ring is the plane contact; the rubber sealing ring has a long service life and the valve has a reliable sealing.
Description
Affiliated technical field
The utility model relates to the valve that uses on a kind of metallurgy industry blast furnace furnace roof, especially a kind of sealed structure of bleeding valve.
Background technology
The bleeding valve of metallurgy industry blast furnace system use at present, general employing metal hard-sealing and rubber sealing double seal, rubber seal is positioned on the plane in the outside of metal o-ring, the part that valve gap contacts with it is pointed projection, when closing, make rubber seal distortion and seal by pointed projection, fragile rubber seal in frequent opening-closing process causes leaking, and influences the sealing of valve.
Summary of the invention
Fragile in order to overcome existing bleeding valve rubber seal, influence the deficiency of valve seal, the utility model provides a kind of sealed structure of bleeding valve.
The technical scheme that its technical problem that solves the utility model adopts is, a kind of sealed structure of bleeding valve, comprise valve gap, valve body, rubber seal, rubber seal is positioned on the end face of inboard valve body of metal o-ring, also have a sealing plate in valve gap, sealing plate is welded as a whole after assembling with valve gap.
The beneficial effects of the utility model are that valve gap is a plane contact with contacting of rubber seal, the long service life of rubber seal, and valve seal is reliable.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural map of embodiment.
Among the figure: 1. valve gap; 2. sealing plate; 3. rubber seal; 4. metal o-ring; 5 valve bodies.
Embodiment
As shown in Figure 1, rubber seal 3 is positioned on inboard valve body 5 end faces of the close circle 4 of metallic hard, on the inclined-plane of valve body 5 and valve gap 1 cooperation, respectively have groove, pile-up welding hard alloy, form metal hard-sealing 4, also have a sealing plate 2 in valve gap 1, sealing plate 2 is welded as a whole after assembling with valve gap 1, forms flat seals with rubber seal 3.
Claims (1)
