Abstract
The utility model discloses a flange structure, in particular to a large-scale ultrahigh-pressure connecting flange structure in a megawatt level fan. The large-scale ultrahigh-pressure connecting flange structure comprises a flange plate and a joint body, and is characterized in that a sealed cutting edge of the joint body, which is near to the flange, is compressed with a metal conical gasket, and a connecting screw is mounted on the flange plate. The flange structure can realize strict sealing under the action of great pulling force of a high-strength bolt by relying on metal deformation between the metal conical gasket and the flange plate, and the using effect of the structure on a large-diameter pipeline is very good. The flange structure can ensure good sealing effect under the ultrahigh pressure state; and the flange structure is reliable for use and long in service life. The flange structure can be used in a connecting structure in a megawatt level wind turbine generator.
Description
Technical field
The utility model relates to a kind of flange arrangement, particularly a kind of adpting flange structure that is used for MW class wind turbine.
Background technique
At present, the adpting flange sealing configuration that uses on conventional wind power generator all adopts rubber seal, but on MW class wind turbine, use common flange, because the big pressure height of adpting flange diameter, under the ultrahigh pressure effect, the adpting flange distortion is big, flange connects amount of deformation and exceeds the compressive strain scope of rubber seal, it is unstable to cause connection pipe fitting to connect, and swing is serious, can't normally use.
The model utility content
The purpose of this utility model is to overcome the defective that exists in the prior art, and the large-sized ultra-high pressure connecting flange structure of a kind of good sealing effect, reliable performance is provided.
The utility model is achieved by the following technical solution:
A kind of large-sized ultra-high pressure connecting flange structure comprises flange plate and fittings body, it is characterized in that: described fittings body sealing cutting edge place has compressed metal awl pad by flange plate, and attachment screw is installed on the flange plate.
Large-sized ultra-high pressure connecting flange structure of the present utility model, it further improves and is: described metal awl pad is the two-way conical surface.
The utility model has solved super large latus rectum hydraulic tubing and has connected the sealing leakage of oil at ultrahigh pressure state lower flange, can't normally use problem.
The utility model fills up sealing configuration with big latus rectum ultra-high pressure connecting flange model utility for adopting the metal awl, rely on the flow of metal between metal awl pad and the flange plate, strict seal under the big tension of high-strength bolt, the sealing surface distortion may appear after a period of time of working under the ultrahigh pressure state, only need this moment get final product tightening screw, this structure using effect on latus rectum pipeline greatly is very good.The utility model guarantees to have good sealing effect at the ultrahigh pressure state; Use reliably, the life-span is long.This practical large-sized ultra-high pressure connecting flange can use on MW class wind turbine.
Description of drawings
Fig. 1 looks generalized section for master of the present utility model;
Fig. 2 looks schematic representation for a left side of the present utility model.
Among the figure: 1, flange plate; 2, fittings body; 3, metal awl pad; 4, attachment screw.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, 2: metal awl pad 3 is designed to the two-way conical surface, and this conical surface and fittings body 2 sealing cutting edges compress by flange plate 1, tighten attachment screw 4 continuously and can realize metallic seal.When occurring becoming flexible, tighten attachment screw 4 once more and can eliminate loosening phenomenon.This product is by attachment screw 4 mounting flanges 1, and pressed joint body 2 and metal awl pad 3 get final product, and what particularly point out is that metal awl pad 3 must be strict with the coaxality of fittings body 2, guarantees that the connecting body cutting edge is axially vertical with metal awl pad 3.After this structure was used, ultrahigh pressure state lower seal is effective, and was easy to maintenance, and the life-span is long.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
