Key Sealing Structure Advantages
Dual-Layer Sealing Defense:Typically employs a composite structure with inner and outer sealing rings. The inner primary seal establishes the initial seal under rated pressure, while the outer auxiliary seal acts as a redundant backup; if the primary seal fails due to impact, the auxiliary seal continues to block leakage paths, significantly enhancing sealing reliability.
Self-Adaptive Compensation: Some models utilize double-lip sealing rings capable of maintaining a stable compression of 0.5 mm to 1.5 mm across a temperature range of -20°C to 120°C. The sealing lips automatically compensate for deformation caused by fluctuations in medium pressure, preventing the formation of sealing gaps.
Design for Special Operating Conditions:Certain models intended for municipal engineering feature water-swelling sealing rings. Upon contact with water, the material expands to fill minute gaps, maintaining seal integrity even in complex geological environments such as quicksand or silt.
Measured Sealing Performance Metrics
Pressure Resistance: Standard industrial-grade double-socket connectors offer a pressure rating of up to 10 MPa and a burst pressure of up to 31.5 MPa, showing no visible leakage when subjected to 1.5 times the rated pressure for 30 minutes.
Ingress Protection (IP) Rating: Certified via third-party IP65 testing; the interior remains dry after 30 minutes of immersion at a depth of 1 meter, effectively resisting the ingress of external water and dust.
Long-Term Stability:Verified through 10,000 mating/unmating cycles. Under normal operating conditions, the sealing ring replacement interval exceeds two years, and the associated piping system boasts a service life of over 50 years, with no significant degradation in sealing performance during long-term operation.
