Abstract

The invention discloses a threaded flange in the technical field of flanges. The threaded flange comprises a protective cover and a protective box, wherein one side of the protective cover and one side of the protective box are each provided with a through opening; the inner wall of each through opening is in threaded connection with a locking mechanism; the inner wall of each protective cover is fixedly connected with a clamping mechanism; the inner wall of the protective box is provided with a disc body; the inner wall of the disc body is fixedly connected with a guide pipe; a thread is arranged on the inner wall of the guide pipe; one end of the guide pipe penetrates through the left side of the protective cover; and the other end of the guide pipe penetrates through the right side of the disc body. According to the threaded flange provided by the invention, through arranging the protective cover and the protective box, the disc body and the guide pipe can be prevented from being damaged; through arranging the locking mechanism, the protective box and the protective cover can be conveniently disassembled; through arranging the clamping mechanism, the disc body can be prevented from moving in the protective box; and through arranging the guide pipe, a pipeline needing to be connected can be guided, so that the threaded flange has the functions of protecting the flange against being abraded and deformed and prolonging the service life.

Description

technical field

[0001] The invention relates to the technical field of flanges, in particular to a threaded flange. Background technique

[0002] Threaded flange refers to a kind of flange that uses threads to connect with pipes. When designing, it can be treated as a loose flange. The advantage is that no welding is required. The thickness of the flange is large and the cost is high, which is suitable for the connection of high-pressure pipelines.

[0003] At present, most of the threaded flanges widely used in the market are integral flanges, and almost no treatment is carried out on the surface of the flange. The service life is shortened. If the flange is deformed during use, the object being connected to the flange may be damaged; when the pipeline is connected to convey materials, the vibration of the pipeline will easily lead to the loosening of the bolts and nuts connected to the flange, resulting in leakage accidents, and For a long time, the nut is easy to rust, ...
