Structural characteristics of rubber joints
1. Spherical rubber body design: The core part of the flexible double ball rubber joint is a spherical rubber body, and its unique shape design makes the joint have a large bending radius and good axial expansion and contraction ability, so as to adapt to various deformations and displacements of the pipeline system.
2. High-strength metal flange: The two ends of the joint are made of high-strength metal flange, which is closely connected with the pipeline through bolt connection. The metal flange has good mechanical properties and sealing properties, which can ensure the stable operation of the joint in harsh environments such as high pressure and high temperature.
3. High-quality rubber material: The joint is made of high-quality rubber material, which has excellent corrosion resistance, aging resistance and wear resistance. This material is able to adapt to the transmission needs of a wide range of media while maintaining good elasticity and tightness.
Product application field
1. Water supply and drainage system: In the water supply and drainage system, because the pipeline may be affected by the foundation settlement, temperature change and other factors and cause deformation and displacement, the flexible double ball rubber joint can effectively absorb these deformations and displacements to ensure the stable operation of the pipeline system.
2. HVAC system: In an HVAC system, pipes need to pass through various structures of the building, such as floors, walls, etc. Flexible double ball rubber joints can flexibly accommodate the deformation and displacement of these structures while ensuring the tightness and stability of the piping system.
3. Petrochemical system: In the petrochemical system, the pipeline medium is often corrosive, high temperature, high pressure and other characteristics. Flexible double-ball rubber joints are able to withstand these harsh environments while maintaining good connection and sealing properties.
Installation and maintenance of flexible rubber joints
1. Installation precautions: When installing flexible double ball rubber joints, attention should be paid to checking whether the model and specifications of the joints match the pipeline system; Ensure that the rubber body and metal flange of the joint are free of damage, cracks and other defects; During installation, bolting should be carried out in accordance with the specified tightening torque to ensure the tightness and stability of the joint.
2. Maintenance method: During use, the flexible double ball rubber joint should be checked and maintained regularly. If abnormal conditions such as leakage and deformation of the joint are found, they should be replaced or repaired in time. At the same time, high-temperature operations such as welding and cutting near the joint should be avoided to avoid damaging the rubber body and metal flange of the joint.
