Abstract

The invention relates to a flange, which includes a neck platform and a disk body, a rotating assembly is arranged between the disk body and the neck platform, and the rotating assembly includes an outer wall connected with the outer side wall of the neck platform facing the disk body in the circumferential direction. A connecting ring, the outer edge of the connecting ring facing the side of the neck platform is connected with a rotating ring in the circumferential direction, the disc body includes a first ring body and a second ring body with the same structure, and the first ring body faces the second ring body. One side of the second ring is circumferentially provided with a rotating groove for the rotating ring to snap into, and the inner side wall of the first ring is circumferentially provided with a connecting groove for the connecting ring to snap into, and the first ring and The second ring bodies are connected by a fixing piece. First, snap the rotating ring into the rotating groove, and then install the second ring body on the first ring body through the fixing piece, and the rotating ring rotates in the rotating groove, so that the disc body can rotate relative to the neck platform, and it is convenient to connect with another Flange connection improves installation efficiency.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to a flange. Background technique [0002] Flange is otherwise known as flange flange or flange. Flanges are parts that are connected to each other between shafts and are used for connection between pipe ends; they are also useful for flanges on equipment inlets and outlets, and can be used for connection between two equipments. Flanges include integral flanges, threaded flanges, plate type flat welding flanges, neck butt welding flanges, neck flat welding flanges, socket welding flanges, butt welding ring loose flanges, flat welding ring loose sleeves Frank et al. [0003] At present, the patent with the publication number CN106439309A discloses a butt welding flange, which includes a disc-shaped flange body, a butt welding portion is arranged on one end surface of the flange body, and the butt welding portion includes a flange body and a flange body. The first hollow truncat...
