What are the advantages of double spherical rubber expansion joints?

Double sphere rubber expansion joint is actually distinguished from single sphere rubber joint in terms of appearance and shape, its installation length is longer than that of single sphere rubber joint, this solves the shortage of rubber joint installation length, when you need to install a longer length of rubber joint, you can use double sphere rubber joint, but double sphere rubber joint is strictly prohibited to install super displacement during installation. When installing double spherical rubber joints on flat ground, overhead or vertically, the actual working axial displacement pressure of the rubber joint is less than the support force of the pipeline, otherwise an anti-pull-off device should be installed to prevent the pressure from pulling off during work. The pipe has fixed support or fixed bracket, and the force of fixed bracket is greater than the axial force. For vertical installation and overhead installation, corresponding fixed brackets and force brackets need to be installed at both ends of the product to prevent pulling off after working under pressure. The installation bolts of double sphere rubber joint should be tightened symmetrically and gradually to prevent local leakage, and the installation should be far away from heat source, and it is strictly forbidden to use media that do not meet the requirements of this product.
 
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. Its double-ball rubber soft joint is mainly wear-resistant and shock-resistant to protect its equipment and related pipeline equipment, which can extend the service life of its equipment and so on. With the innovative development of social science and technology, double-ball rubber joints as an emerging technology synthetic material has been chosen by more and more industries, and the scope of use and application is very wide. This material plays a special role in industrial and mining enterprises, transportation sector and construction industry housing ground, etc.
