1. Overview.
RS type flexible casing expander is a kind of compact structure and excellent performance of pipeline connectors, mainly composed of casing, sealing ring, compression flange, etc., which can effectively compensate for the thermal expansion and contraction of pipelines, reduce the vibration and noise of pipelines, and improve the service life of pipelines. The retractor is suitable for a wide range of piping systems, especially those that need to withstand high pressures and high vibrations.
Second, the working principle.
The working principle of RS type flexible casing expander is mainly based on the principle of thermal expansion and cold contraction, by setting an expander in the pipeline, the pipeline can be freely expanded and contracted, so as to adapt to the change in pipe length caused by temperature change. When the temperature rises, the pipe expands and the expander lengthens accordingly, thus absorbing the expansion of the pipe;When the temperature decreases, the pipe shrinks and the expander shortens accordingly, thus releasing the shrinkage of the pipe. In this way, the retractor can effectively reduce the vibration and noise of the pipeline, and reduce the stress caused by temperature changes, and improve the service life of the pipeline.
3. Features and advantages.
1.Simple structure: RS type flexible casing type telescopic device is compact in structure, easy to install, and does not require complex auxiliary equipment.
2.Stable performance: The telescopic device is made of high-quality materials, after precision processing and testing, it has excellent corrosion resistance, wear resistance and high temperature resistance, which can ensure long-term stable performance.
3.Large compensation amount: RS type flexible casing telescopic retractor has a large compensation amount, which can meet the compensation needs of various pipeline systems.
4.Reduce vibration and noise: The retractor can effectively absorb the vibration and noise of the pipeline, and reduce the impact of vibration and noise on the pipeline system.
5.Increased service life: The service life of the pipe can be increased due to the reduction of stress caused by temperature changes in the retractor.
Fourth, the field of application.
RS type flexible casing expander is widely used in various pipeline systems, such as water supply and drainage, heating, air conditioning, fire protection and other pipeline systems in petroleum, chemical, electric power, construction and other industries. Especially in some piping systems that need to withstand high pressure and vibration, RS type flexible casing expander is an indispensable and important component.
5. Installation and maintenance.
1.Installation: When installing the RS type flexible casing type telescopic retractor, you should ensure that the position and orientation of the retractor are correct, and follow the installation instructions. During installation, care should be taken to avoid excessive compression or stretching of the retractor to avoid damaging the internal structure of the retractor.
2.Maintenance: In order to maintain the normal operation and service life of the retractor, the retractor should be inspected and maintained regularly. The inspection includes: checking whether the appearance of the retractor is damaged or deformed;Check that the seal is intact;Check whether the bolts of the compression flange are loose, etc. If an abnormal situation is found, it should be repaired or replaced in time.
VI. Conclusions. As a kind of pipe connector with compact structure and excellent performance, RS flexible casing expander has a wide range of application prospects. Its excellent performance and stability can provide reliable guarantee for various pipeline systems and improve the service life and safety of pipelines. In the future, with the continuous progress of technology and the continuous expansion of application fields, RS type flexible casing telescopic retractor will play a more important role.
