Flange structure with pipe diameter easy to adjust and mount

Abstract

The invention relates to the technical field of flange structures, and discloses a flange structure with the pipe diameter easy to adjust and mount. The flange structure comprises a first pipeline, afirst flange is arranged on the outer surface of the first pipeline, a limiting groove is formed in the top of the first flange, the first flange is provided with a limiting rod, the other end of thelimiting rod is provided with a pull block, a connecting rod is arranged on one side of the bottom of an inner cavity of the limiting groove, a movable block is arranged in the middle of the outer surface of the connecting rod, a top block is arranged on the top of the connecting rod, and the bottom of the movable block and the inner wall of the limiting groove are in transmission connection through a spring located on the connecting rod. According to the flange structure with the pipe diameter easy to adjust and mount, through cooperation of the limiting rod, the connecting rod, the movable block and the spring, the first flange and the first pipeline can be conveniently and better fixedly connected together, the problem that in the connecting process of the first flange and the first pipeline, welding is carried out through the welding device is solved, and the portability of mounting in the first flange can be improved.

Description

Technical field [0001] The invention relates to the technical field of flange structures, in particular to a flange structure whose pipe diameter is easy to adjust and install. Background technique [0002] Flange is a part that connects between shaft and shaft. It is mainly used for connection between pipe ends. The flange structure is mostly used in pairs during use. Nowadays, flanges are installed on one end of the pipe. Welding is often used, so that the pipes on the welded flanges need to be removed with a lot of effort, and when there is a gap at the pipe connection, it is necessary to cut off one end of the pipe and use it at the same time When the flange is installed with two steel pipes, a gap is likely to remain at the connection, which will affect the normal use of the pipeline connection, and cause leakage problems during the use of the pipeline. Summary of the invention [0003] (1) Technical problems solved [0004] In view of the shortcomings proposed by the above-m...

Problems solved by technology

[0002] Flanges are parts that are connected to each other between shafts. They are mainly used for the connection between pipe ends, and the flange structure is mostly used in pairs during use. Nowadays, flanges are installed on one end of the pipe When welding is often used, it takes a lot of effort to remove the pipes on the flange after welding, and when there is a gap at the joint of the pipe, one end of the pipe needs to be cut off, and at the same time use When the flange is used to install two steel pipes, there is likely to be a gap at the joint, which will affect the normal use of the pipe connection and cause leakage problems during the use of the pipe.
