Structural characteristics of double spherical rubber expansion joint.
The rubber joint's inner rubber layer is made of high quality rubber with good surface smoothness, and the resistance rate of the medium is not large, so the liquid, slurry and its granular material and gas pipeline are available. The outer rubber layer is made of high quality aging resistant rubber, which can generally resist various environmental corrosion, especially with aging resistance to ensure the service life of rubber joints, and the surface will not show cracks or fracture layer degumming under certain light conditions.
The inner layer of the double sphere rubber expansion joint is made of high quality polyester 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 in the process of use, and can be restored to its original state after shrinking deformation. In the neck part of the double spherical rubber expansion joint, our company uniquely designs the patented strengthening collar according to the user's embodied use condition, which has good pressure resistance and ensures the weaker part of the rubber joint, especially when it is used in more than 2.0MPa Kor pressure, it is necessary to modify the equipment. All the double spherical rubber expansion joints have no weak points.
The double spherical rubber expansion joints are produced with good elasticity and toughness, and are commonly used in various pipeline compensation, especially in power plants for the compensation of displacement settlement and noise absorption of long distance pipelines of large diameter circulating water pipelines. In the desulfurization tower as available in our plant rubber joints because of strong corrosion resistance and high wear resistance, so for the lime slurry pipeline compensation has a very significant role in the desulfurization tower commonly used. Our double spherical rubber expansion joint has a significant shock absorption and noise reduction effect in the centrifugal water pump mouth modification to ensure the sealing of the pipeline, because the rubber joint absorbs pipeline vibration and therefore prevents the pipeline bolts from falling down by vibration. Therefore, rubber joints are a very good choice for pipeline vibration and noise damping and compensation for displacement and settlement.
