Structural advantages of single flange limited expansion joint

Single flange limit Expansion joint It is composed of loose sleeve expansion joint and limit short pipe. In addition, self-protection measures and limit device are added to prevent leakage or damage of expansion joint caused by excessive displacement of pipeline. It is usually used in the position where one side is connected with flange and the other side is welded with pipeline. During installation, the gland bolts should be tightened diagonally in turn, and then the limit nut should be adjusted to achieve the installation effect of force balance.

The single flange limited expansion joint provides great convenience for the installation and replacement of various water supply and drainage pipelines, water towers, pumps, water meters and valves, and plays a good role in regulating the expansion and contraction of long-distance pipelines due to temperature difference. It is widely used because of its good comprehensive performance, so what good effect is there in the structure of the product itself?

Due to the safety of the expansion joint, the use of single flange should be considered Telescopic device The diameter of ¢ 2700 is larger, the design common pressure is 1.7mpa, and the test pressure is 2.55mpa. It is necessary to study the safety performance comprehensively, analyze the various forces on the expansion joint, and calculate its influence on the expansion device.

2. The design of single flange limited expansion joint should consider its technical performance and fully analyze the influence of various working conditions on its performance to meet the design requirements.

3. The design of single flange limit expansion joint should consider its economy, simple structure and easy machining. It can be processed by ordinary equipment, and the production cost can be reduced.

4. The design of single flange limited expansion joint should consider its material selection, small weight, convenient transportation, convenient lifting and installation on site, and multi-party research on structural design to adapt to future maintenance.

5. New technology and new invention patent should be considered in the design of single flange limited expansion joint, so as to improve the product quality.
