Generally we use more single sphere rubber expansion joints, but the pipeline will also be used in the design of double sphere rubber joints, double sphere rubber soft joints are much stronger than the general rubber soft joints, double sphere rubber soft joints key to use the distinctive characteristics of rubber, such as high elasticity, high sealing, material resistance and radiation resistance, the choice of high strength, cold and heat stability of polyester fabric curtain and rubber surface, by The product structure is designed with high inner hole arc and long curve, and has a great variety of offset effects. It is especially used in sites where the geological environment is complicated, and the hot and cold transformation in the operation of the pipeline at the diamond level often leads to pipeline damage, and the elastic sliding displacement of rubber and the heat conduction and dissipation of the mechanical force of deformation are used reasonably. The removal of the pump, valve and pipeline itself deflection physical damage. This is the advantage of double sphere rubber joint, but also its disadvantage, because it is a double sphere, so the length of the sphere is twice as long as the general sphere, so that the pipeline use, excessive pressure plus the vibration of the pipeline will lead to rubber joint sphere tear, which is also the disadvantage of double sphere rubber joint in the process of use. The size of the product is added to the product with iron ring, and then the middle of the ball belly, which can avoid the ball rupture caused by the excessive pressure. It can make the double-ball rubber joint both play its strong elasticity and good shock absorption effect, and can be used in high pressure environment.
