The role of the reinforcement ring of double spherical rubber joints and its installation
Double spherical rubber joints because of the application of rubber joints and their own structural limitations, so in the application of double spherical rubber joints will see a metal ring between the two expansion joints, set on top of the rubber expansion joint, many users do not know much about the function of the parts, often due to the set of metal rings, worry about causing double spherical rubber joints compensation function decline, we are today targeted first Today, we will focus on the double sphere rubber joint.
Double spherical flexural rubber joint rubber expansion joint parts with metal reinforcement ring can effectively avoid the rupture of the rubber expansion joint in a high-pressure environment, but also to solve the defects of the double spherical rubber joint low pressure-bearing capacity, double spherical rubber joint connection generally has a fillet connection, flange connection and clamp connection and other ways. Its sphere is composed of inner rubber layer, reinforcement layer with multiple layers of scraped nylon cord fabric, and outer rubber layer compound rubber tube. According to the different media used in the rubber material is also different, including natural rubber, butyl rubber, butyl rubber, nitrile rubber, EPDM rubber, neoprene, silicone rubber, fluorine rubber and so on a variety of materials. They are heat-resistant, acid-resistant, alkali-resistant, corrosion-resistant, wear-resistant, oil-resistant and so on.
Mainly by lengthening the rubber joint support mold, to do the lengthening of the rubber joint, but in the manufacturing process, due to the impact of the structure of the rubber expansion joint, will cause the double sphere bendable rubber joint in the manufacturing process, the amount of rubber between the two adjacent rubber expansion joints is not enough to cause the rubber expansion joint direct wall thickness is thin, resulting in a decrease in pressure-bearing capacity, so our company specifically for this situation, in the double sphere bendable Therefore, our company specially for this situation, in the rubber expansion joint part of the double sphere bendable rubber joint, add metal reinforcement ring, effectively avoid the rupture of the rubber expansion joint in the high pressure environment.
The rubber is soft, which can reduce vibration and noise, and can compensate for the heat and cold shrinkage caused by temperature change, so it is the key influence of double sphere rubber joints in pipeline system software. Double sphere rubber soft joints in the case of installation prohibit super offset limit installation. The installation of the foot bolt should be symmetrical, gradually filled with pressure and tightened to prevent partial leakage. 1.6MPa above the pressure, the installation of the foot bolt should have a ductile pressure pad to prevent the foot bolt from loosening during work. When installed vertically, there should be vertical bearing support on both sides of the connection head pipeline, and anti-pull-off equipment can be used to avoid pulling off during work.
