Abstract
The utility model relates to a weldbonding flange specialized for wind nuclear power, which is characterized in that the flange takes a shape of a ring, the middle of the back of the flange takes a shape of a straight lug boss (1), the middle of the front of the flange takes a shape of a transition arc lug boss (2), and the center hole of the flange is a counterbore (3); and a plurality of bolt holes (4) are axially arranged on a flange plate surrounding the flange. As the seal face of the utility model adopts a lug boss structure, when being deformed with cold, only the flange plate is deformed to a certain extent, whereas the seal face is not influenced, sealing is not easy to be aged and deformed, and using time becomes much longer, thus particularly satisfying the demands of strength, weldability and weatherability required by a special flange for wind nuclear power.
Description
Technical field
The utility model relates to a kind of flange, is specifically related to a kind of wind nuclear power special use and accepts the weldering flange.Belong to the metal connecting piece technical field.
Background technique
Flange is requisite parts during pipeline connects, applied range.The pipeline adpting flange adopts two Flange Plane to add a mat mostly at present, tightens the screw then, by crush seal.The defective of its existence is fastening yielding, and it is tightly flat to be difficult for centering.Therefore, adopt present flange connection, because cold and hot distortion, wriggle in the flange plate contact position, and therefore very easy leakage after sealing gasket is aging can not satisfy the needs of special flange for wind nuclear power to intensity, weldability and weatherability.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of fastening on-deformable wind nuclear power special use to accept the weldering flange.
The purpose of this utility model is achieved in that a kind of wind nuclear power special use accepts the weldering flange, it is characterized in that:
Described flange is circular,
In the middle of the described flange back side is straight boss shape, the positive middle band transition arc boss shape that is, and the flange center hole is a counterbore;
Axially be provided with some bolts hole on the described flange peripheral flange.
The utility model is because seal face adopts boss structure, have only flange plate to be subjected to certain deformation when being subjected to cold deformation, and seal face is unaffected, sealing is difficult for aging distortion, service time is more permanent, therefore can satisfy the needs of special flange for wind nuclear power to intensity, weldability and weatherability especially.
Description of drawings
Fig. 1 is the vertical section structure schematic representation of the special-purpose welding neckflange of the utility model wind nuclear power.
Among the figure: straight boss 1, band transition arc boss 2, counterbore 3, bolt hole 4.
Embodiment
Referring to Fig. 1, the weldering flange is accepted in the wind nuclear power special use that the utility model relates to, and this flange is circular, is straight boss 1 shape in the middle of the flange back side, positive middle band transition arc boss 2 shapes that are, and the flange center hole is a counterbore 3; Axially be provided with some bolts hole 4 on the described flange peripheral flange.
