Abstract

The utility model relates to a special welding neck flange for wind power nuclear power, which is annular, wherein the back middle of the flange is shaped as a boss (1), the front middle of the flange is shaped as an end cutting cone (2), the head of the end cutting cone (2) is in a short cylinder form (2.1) whose head is shaped as a chamfer (2.2), the flange plate at the periphery of the flange is axially provided with a plurality of bolt holes (3). The pressing surfaces of the utility model adopt a boss and an end cutting cone, therefore, when is deformed in cold, only the flange plate is deformed and the pressing surfaces are not affected, the seal is not easy to age and deform, thereby prolonging service life, to satisfy the strength, welding ability and weathering resistance demands of the special flange in the wind power nuclear power technical field.

Description

The special-purpose welding neckflange of wind nuclear power
Technical field
The utility model relates to a kind of flange, is specifically related to the special-purpose welding neckflange of a kind of wind nuclear power.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-purpose welding neckflange.
The purpose of this utility model is achieved in that the special-purpose welding neckflange of a kind of wind nuclear power, described flange is circular, is the boss shape in the middle of the described flange back side, is frusto-conical in the middle of the front, described frustum of a cone head is the short cylindrical shape, and the short cylindrical head is arranged to the chamfering shape; Axially be provided with some bolts hole on the described flange peripheral flange.
The utility model is because seal face adopts boss and frustum of a cone structure, when being subjected to cold deformation, have only flange plate to be subjected to certain 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: boss 1, frustum of a cone 2, short cylindrical 2.1, chamfering 2.2, bolt hole 3.
Embodiment
Referring to Fig. 1, the special-purpose welding neckflange of the wind nuclear power that the utility model relates to, this flange is circular, in the middle of the flange back side is boss 1 shape, in the middle of positive is frustum of a cone 2 shapes, and described frustum of a cone 2 heads are short cylindrical 2.1 shapes, and short cylindrical 2.1 heads are arranged to chamfering 2.2 shapes; Axially be provided with some bolts hole 3 on the described flange peripheral flange.

Claims (1)
