Description

A flange for easy connection

technical field

The utility model relates to the technical field of flanges, in particular to a flange that is convenient for connection.

Background technique

Flanges, also known as flange flanges or 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. Flanges are widely used. Used in various industries, such as construction, light and heavy industry, plumbing, electricity and so on.

In order to improve the tightness and stability of the connection between the pipes, most of them use flanges to connect the two pipes together. For example, the existing patent is a matching flange that is easy to connect and has good sealing performance. The patent number is CN2020213735276. The flange is clamped by using the groove and the protrusion provided on the second flange, and there is a cuboid-shaped gap after the groove and the protrusion are clamped, and it is fixed by using a fixing pin into the gap. Thereby the effect of accurate butt joint is achieved. At the same time, threaded holes are opened on the first flange and the second flange, and the screw is tightened and fixed again, thereby achieving the effect of double fixing and improving the first flange. The firmness of the connection with the second flange.

However, in actual use, when the flanges are installed, the pipes are firstly fixed on one flange and welded, and then the two flanges are fixed by many bolts, the two pipes are prone to shake during the butt joint, resulting in grooves and The clamping of the bumps is extremely inconvenient and cannot be installed quickly. It is time-consuming and labor-intensive to install, requiring a lot of manpower and time, and the long-term use of the bolts will cause the problem of loosening and falling off due to the vibration of the pipeline itself.
