Abstract
Description
Technical Field
[0001] The utility model relates to a pipeline connector, in particular to a fiberglass reinforced plastic flange. Background Art
[0002] For the existing conductive fiberglass reinforced plastic flange, its main design principle is to add 10-20% of conductive graphite powder into the formed resin matrix material, and disperse and stir it to achieve the conductivity of the flange.
[0003] Technical disadvantages of the flange that conducts electricity by adding graphite powder:
[0004] First, the dispersion is uneven and it is easy to precipitate, seriously affecting the conductivity;
[0005] Second, after adding the conductive powder, the glue liquid is viscous and the winding forming process is poor;
[0006] Third, the conductive powder needs to be ground separately, and the process is complex;
[0007] Fourth, the comprehensive cost is high and the efficiency is low;
[0008] Fifth, the strength and brittleness of the product increase. Content of the Utility Model
[0009] The technical problems solved by the utility model: For the existing conductive fiberglass reinforced plastic flange, the conductivity is not good and the strength and brittleness of the product are large.
[0010] To solve the above technical problems, the utility model provides the following technical solution: A conductive fiberglass reinforced plastic flange includes a socket opened at the center position of the flange, a connection part arranged at one end of the flange, and a plurality of bolt connection holes circumferentially distributed on the connection part. A first conductive layer and a second conductive layer are arranged on the inner wall of the socket, the first conductive layer is located on the periphery of the second conductive layer, a third conductive layer is arranged on the end face of the connection part, and one end of the first conductive layer is bent and closely attached to the third conductive layer.
[0011] The end of the bent end of the first conductive layer is bent, the end of the bent end of the first conductive layer is perpendicular to the third conductive layer, and the end of the bent end of the first conductive layer is embedded in the flange.
[0012] The end of the bent end of the first conductive layer is located on the periphery of the bolt connection hole and close to the outer edge of the connection part.
[0013] The utility model converts the conductive flange formed by dispersing and stirring conductive graphite powder in the resin matrix in the traditional process into the conduction between the inner wall of the flange socket and the back of the flange. The flange connection uses a steel bolt connection. Therefore, the pipeline connected by the flange is a conductive whole body, and the conductivity of the product is excellent.
