AI Technical Summary
Traditional flanges have unstable sealing performance under high pressure and high frequency vibration conditions, are prone to leakage, have low installation efficiency, and are difficult to adapt to the thermal expansion and contraction of pipelines and the deformation caused by vibration, resulting in loose connections and media leakage.
The mechanical elastic structure is adopted, and dynamic sealing is achieved by the cooperation of the sealing ring and the reserved insertion groove, combined with the elastic compensation mechanism of the compression spring; the thread self-locking characteristics of the screw cap and the geometric engagement of the limit block are used to prevent the connection from loosening.
Under high pressure and high frequency vibration conditions, ensure that the sealing ring and the pressure plate are tightly fitted to prevent media leakage, improve sealing reliability, reduce leakage risk, improve installation efficiency and extend maintenance cycle.
