What is the difference between single-arch rubber joints and double-arch rubber joints
Single ball rubber expansion joint, double ball rubber expansion joint literally can also see the general difference, first of all, from the advantages of its shape characteristics, poor double ball than single ball long, so the amount of compensation and offset are relatively large angle is relatively large. Single ball rubber expansion joint, double ball rubber expansion joint what are the specific differences.
Introduction of single sphere rubber expansion joint
Single sphere rubber joint adopts single ball integrated design, the overall connection is well sealed, thus ensuring that the sealing and pressure-bearing performance of the product can reach a good height. Compared with mechanical expansion and contraction and packing damping, rubber joints occupy little space, are light in weight, easy to install and disassemble, save labor and low cost. For the same limited capacity, there is no need to increase the pump and pipe diameter. The smooth inner wall of rubber joints reduces the resistance of fluid and does not damage the body of fittings. With good water tightness, no need to add pad in installation. Wide range of application: choose different rubber formulations to make the product with various properties such as heat resistance, oil resistance, corrosion resistance, aging resistance, wear resistance, ozone resistance, etc.
The difference between single-ball rubber joint and double-ball rubber joint For double-ball rubber joint, because it is made of two rubber spheres, the middle part of the joint has the phenomenon of pressure-bearing short plate, in theory, the double sphere is less than single-ball rubber joint due to the influence of the structure. The sphere part of the single sphere rubber joint is made of single sphere, so the displacement compensation is a little bit lacking, especially the axial displacement and angular displacement compared to the more obvious double sphere rubber joint compensation range can reach one times of the former, so the double sphere rubber joint is very advantageous in terms of rubber joint displacement compensation.
Introduction of double sphere rubber expansion joint
The middle layer of double-ball rubber joint adopts good nylon cord fabric and hard steel wire welded rubber joint skeleton layer, which has good strength to ensure that the rubber joint will not be stretched and torn during use, and can also recover well after compression deformation. The high toughness of nylon cord fabric is the guarantee of rubber joint toughness, while the steel wire collar reinforcement layer is the guarantee of rubber joint strength.
The special design of reinforcing collar according to the use situation reflected by users makes it have good pressure resistance to ensure the weak part of rubber joints, especially when used in high pressure above 2.0MPa, with the addition of secondary devices. Make the whole double ball rubber joint's own combination without weak link. Because of its good elasticity and toughness, the double ball rubber joint is widely used in various pipeline compensation, especially in thermal power plants for long distance pipeline displacement compensation and noise absorption of large diameter circulating water pipeline. It is also applicable in the desulfurization tower.
