Flange, also called flange or flange. The flange is the connecting part between the shafts and is used to connect the pipe endsFlanges are important connectors and are used in a large number of practical projects.. Can also be used as equipment inlet and outlet flange, for the connection between two pieces of equipment, such as reducer flange. Flange connection or flange joint refers to the detachable connection with flange, gasket and bolt as a set of combined sealing structure. Pipeline flange refers to the flange used for pipeline distribution in pipeline equipment. When used in equipment, it refers to the inlet and outlet flanges of the equipment. The existing flange structure includes an outer circle, an inner circle and a guard plate, which connects the outer circle and the inner circle,The current flange manufacturing process for the square billet or round billet directly cutting, drilling, processing time is long;The flange is heavy, the structure is complex, and the disassembly and assembly are inconvenient; and the number of threaded connection holes on the existing flange is usually fixed, so it must be used in conjunction with the assembly, and the adaptability is poor. To this end,NecessaryA flange that can be more easily disassembled and assembled by adjusting the number of threaded connection holes is studied.
In order to overcome the defects of the prior art, technicians provide a new type of flange that can adjust the number of threaded connection holes and has strong assembly adaptability. In order to achieve the above objectives,It uses the followingTechnical schemeImplementation: the paragraphThe flange includes a flange body, the flange body is provided with a central hole, the outer edge of one side of the flange body is provided with a first annular convex ring, the same side end face of the central hole is provided with a second annular convex ring, and the first annular convex ring and the second annular convex ring have the same thickness. A plurality of connecting blocks are arranged in the receiving groove formed by the first annular convex ring and the second annular convex ring, and the two end surfaces of the connecting blocks are matched with the inner surface of the first annular convex ring and the outer surface of the second annular convex ring. The connecting block is provided with a threaded connection hole, and a positioning structure is provided between the connecting block and the first annular convex ring.
In the production of the flange need to pay attention:The positioning structure includes a plurality of damping positioning grooves arranged on the first annular convex ring, an elastic damping layer is arranged in the damping positioning grooves, a card rod matched with the damping positioning groove is arranged on the connecting block, and the end of the card rod is provided with Limit part. The surfaces of the first annular convex ring and the second annular convex ring are both provided with wear-resistant meshes.
Thenew typeFlangeThe advantages and beneficial effects are:One isA first annular convex ring and a second annular convex ring are arranged on the two end faces of the flange body, a connecting block is arranged between the first annular convex ring and the second annular convex ring, and a threaded connection hole is arranged on the connecting block, By changing the number of connecting blocks,To achieve the purpose of adjusting the number of threaded connection holes, more adaptable;Second, by optimizing the structure,When removing, loosen the bolt and move the connection piece outward along the waist hole, that is, away from the center of the upper flange until the upper cross plate is separated from the upper flange,makeFlangeThe disassembly and assembly are more convenient and practical.
