Performance characteristics of double ball rubber joints
1. Flexibility: The double-sphere design greatly enhances the flexibility of the joint, so that the pipeline system can flexibly cope with the small displacement caused by natural factors such as earthquakes, temperature changes or land subsidence, effectively absorb and disperse these stresses, protect the pipeline from damage, and ensure the long-term stable operation of the system.
2. Weather resistance and aging resistance: The rubber material of the double ball rubber joint is specially formulated, which not only has good weather resistance and aging resistance, but also maintains stable physical and chemical properties in a wide range of temperatures. This means that it retains excellent sealing and elasticity in both the extremely cold northern regions and the scorching tropical environment, preventing media leakage and ensuring production safety.
3. Sealing: It adopts a specially designed sealing structure inside, which can effectively prevent the leakage of the medium and ensure the safe and stable operation of the pipeline system. At the same time, its sealing performance is also reflected in the isolation of the external environment, which can effectively prevent the intrusion of external impurities and moisture, and prolong the service life of the pipeline.
4. Low resistance: The inner wall is smooth and the fluid resistance is small, which is conducive to the smooth flow of the medium and reduces energy consumption and noise pollution.
5. Shock absorption and noise reduction ability: In the process of fluid transportation, the double ball rubber joint can effectively absorb the vibration of the pipeline, reduce the impact of mechanical vibration on the surrounding environment and equipment, and create a more quiet and comfortable working environment for the staff.
Scope of use
Double ball rubber joints are widely used, mainly used in various piping systems, especially in the need for shock absorption, noise reduction, and compensation for thermal expansion and contraction caused by temperature changes. This kind of joint is favored because of its high elasticity, high air tightness, medium resistance and weather resistance, and is widely used in basic engineering fields such as chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electric power and so on.
