Description
Technical Field
The utility model relates to a flange field especially relates to an angularly adjustable reducing flange.
Background
The flange is widely applied and mainly has the function of connecting and fixing two parts together. When the flange is used, the two flanges are fixedly connected through bolts. Therefore, it is required that the concentricity of the bolt holes of the two flanges to be connected with each other is high, otherwise the connection and fixation of the two parts cannot be smoothly performed. The flange has very wide application in the fluid industry and can bear larger pressure. Sometimes, under special working conditions, pipelines with different sizes are needed to be used at two ends of the flange, and the angle of an outlet pipeline needs to be changed, so that the special space of supporting facilities is reduced; therefore, it is desirable to provide a reducing flange with an adjustable outlet pipeline angle and convenient installation.
