In daily use, the role played by single ball rubber soft joints and double ball rubber joints between metal pipelines is easily overlooked, but they are also crucial.
Single ball rubber joint is a hollow rubber product used for portable connection between metal pipelines. It consists of inner and outer layers of rubber, cord layers, and steel wire rings to form a tubular rubber component. After being thinned and formed, it is loosely combined with metal flanges or parallel joints. Not only can it reduce vibration and noise, but it can also compensate for thermal expansion and contraction caused by temperature changes, and is widely used in various pipeline systems.
The structure of the double ball rubber joint is basically the same as that of the single ball rubber joint, but the installation length is larger than that of the single ball rubber joint, because the double ball connection method is used.
In terms of usage range, the single sphere rubber joint has the same usage range as the double sphere rubber joint. Due to the double sphere rubber joint being used, the connection length of this type of rubber joint is better than that of the single sphere rubber joint,
Compared to the compensation amount of a single spherical rubber joint, a double spherical rubber joint has a greater compensation amount and deflection angle.
However, the safety performance of the double ball rubber expansion joint is not as high as that of a single ball, so it is necessary to pay attention to it in general use, especially when it is prone to bursting at the transition point of the double ball rubber joint. Based on this usage method, our factory has developed a double ball rubber joint pressure increasing protection device suitable for pressure bearing, which can effectively protect the stability of the ball. Sudden pressurization during use can also provide good protection.
