Abstract
The utility model discloses a large-flange sealing device, and relates to the large-flange sealing of gasification furnace shells for the petrochemical industry, the coal chemical industry and the like. According to the large-flange sealing device, a lip seal ring is welded on each of the two sides of a large flange, and is a stainless steel forged piece. The large-flange sealing device has a simple structure, is easy to popularize, and can be used for sealing in a field welding way when leak happens.
Description
Technical field
The utility model relates to the sealing of the big flanges of gasification oven housing such as petrochemical industry, Coal Chemical Industry, is specifically related to big flange sealer.
Background technique
Along with the development of coal gasifying process, the especially development of water cooled furnace wall gasification technology generally uses conventional flange seal that the water cooled furnace wall internals are installed in the gasification oven, the back is installed if leak, and just must repair sealing surface.So how effective seal becomes a big difficult point to the big flange of gasification oven, selects for use a kind of safe and reliable sealing to have very important realistic meaning.
Summary of the invention
The utility model is in order to solve conventional flange seal, if leak, and the problem that just must repair sealing surface, and a kind of big flange sealer is provided.
The utility model is realized through following technological scheme:
A kind of big flange sealer, at the big bilateral welding ring lip seal of flange, described ring lip seal is a stainless steel forgings.
The structural type of ring lip seal is welded on the big flange of gasification oven, and effectively reliable for what guarantee to seal, the ring lip has adopted independently stainless steel forgings, processes after through bilateral welding with big flange, plays effective seal.
The utility model is simple in structure, is easy to promote, and when occurring leaking, can realize sealing through field welding.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: the big flange of 1-, 2-encircle lip seal.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
A kind of big flange sealer as shown in Figure 1, at big flange 1 bilateral welding ring lip seal 2, described ring lip seal is a stainless steel forgings.
Claims (1)
1. a big flange sealer is characterized in that described ring lip seal is a stainless steel forgings at the big bilateral welding ring lip seal of flange (1) (2).
