A rotary joint is a connecting device used in a piping system to connect two sections of pipeline and realize the function of rotation and rotation. It can be applied in various fields, such as petroleum, chemical, paper, food, pharmaceutical, etc.
1.The principle of the rotary joint
The principle of the swivel joint is to use floating bearings and sealing devices to provide a rotary connection between two pipes, so that the pipes at both ends can rotate freely within a certain angle range. Its main components include fixed flanges, rotating flanges, guide bearings and sealing devices. The fixed flange and the rotating flange are fixed on the two sections of the pipeline by bolts and other connections, and the guide bearing is installed between the rotating flange and the fixed flange to play the role of support and guidance. The sealing device includes a type 0 sealing ring, a sealing gasket, etc., which is used to ensure the sealing performance of the joint.
2.The role of the rotary joint
1). Alleviate pipeline stress: In the pipeline system, due to temperature changes, pipeline expansion, settlement, etc., it will lead to stress concentration in the pipeline, and if there is no rotary joint, these stresses may cause pipeline deformation, cracking and even rupture. The swivel joint can make the pipeline rotate freely within a certain range through its rotation function, thereby relieving the stress of the pipeline and protecting the integrity of the pipeline.
2). Compensate for pipeline displacement: In the pipeline system, due to the influence of temperature changes, pressure changes and other factors, the pipeline may have a certain displacement. The rotary joint can make the pipeline rotate and rotate freely within a certain range through its rotation function, so as to compensate and adjust the displacement of the pipeline and maintain the normal operation of the pipeline system.
3). Provide flexibility and reliability: The rotary joint can provide a certain degree of flexibility and reliability, so that the pipeline system can better adapt to various complex working conditions and environmental changes during operation. It can reduce the maintenance cost of the pipeline system and prolong the service life of the pipeline.
4). Reduce vibration and noise: In the piping system, due to the shock and vibration of the fluid, a certain amount of vibration and noise may be generated. Swivel joints can reduce the transmission of pipeline vibration and noise through their rotation and cushioning functions, and improve the safety and comfort of the working environment.
It is worth noting that the design and selection of rotary joints should take into account the working conditions, medium characteristics, pressure, temperature and other factors of the pipeline to ensure the safe and reliable operation of the joints. In addition, for some special environments, special treatments such as anti-corrosion and high temperature resistance are also required to meet the corresponding work requirements beg.
3.Summary
In summary, as an important pipeline connection device, the rotary joint can effectively alleviate pipeline stress, compensate for displacement, provide flexibility and reliability, reduce vibration and noise, and protect the safe operation of pipeline through its rotation and cushioning functions. In various pipeline systems, rotary joints play an important role, providing an important technical guarantee for the normal operation and maintenance of pipeline systems.
