Why do double ball rubber joints have a good seal?
The double ball rubber joint has good sealing, mainly due to its unique double-layer ball structure and reinforced skeleton layer design This design not only improves the overall pressure performance of the seal, but also has significant advantages in terms of resistance to fatigue, wear and aging. Specifically, the sealing performance of the double-ball rubber joint is good for the following reasons:
1. Double-layer ball structure: The double-sphere rubber joint adopts the inner and outer layers of glue, which is made of high-quality synthetic rubber materials, which has good oil resistance, water resistance, corrosion resistance and other characteristics, which ensures the long-term performance of the joint in a variety of media. This structure significantly increases the tensile strength and tear resistance of the joint, allowing it to remain structurally intact in the face of pressure fluctuations and mechanical vibrations.
2. Reinforced skeleton layer: The middle layer is made of high-strength nylon cord fabric and hard steel wire welded skeleton layer, which gives the double ball rubber joint excellent strength and toughness. With its excellent tensile resistance and tear resistance, nylon cord fabric provides a good foundation for toughness for rubber joints; The wire ring reinforcement layer is like a strong armor, effectively resisting external pressure, ensuring that the joint can still maintain a stable shape under extreme working conditions, and can quickly return to its original shape even after compression deformation, prolonging the service life.
3. Technical advantages: Double ball rubber joints are widely used in many fields, including the chemical and petroleum industries, because of their excellent performance. In chemical plants and oil pipelines, it can effectively resist the erosion of various chemical media, and at the same time reduce the stress caused by thermal expansion and contraction, vibration and other factors in the pipeline, so as to ensure the stable operation of the system.
