Luoying manufacturers to speak about the characteristics of double-arch rubber expansion joint.
Nov-22-20
Double-arch rubber expansion joint is mainly composed of rubber spheres and flanges at both ends, the rubber is soft, can significantly reduce the vibration and noise of the pipeline system, can be pressed to deal with a variety of pipeline socket offset, radial expansion type and different axis degree, and can be caused by temperature changes in thermal expansion and contraction of its compensation role, so it is destined to double-arch rubber expansion joint in the pipeline system of the important position.It has the characteristics of single-arch rubber expansion joint (reduce vibration and noise, the role of thermal expansion and contraction, the use of a variety of pipeline systems), and is used in the same area. From the advantages of its appearance characteristics, it seems that the weaker double arch is longer than the single arch, and thus the amount of compensation and displacement is large.
Double-arch rubber expansion joint sphere is composed of inner rubber layer, reinforcement layer with multiple layers of scraped nylon cord fabric, outer rubber layer composite rubber tube. Double-arch rubber expansion joint can be radial expansion in a certain area, but also at a certain angle to get rid of the deviation of different radial pipeline connections, can largely facilitate the assembly and disassembly of the gate valve pipeline, pipeline allowable expansion can be arbitrary expansion, once the expansion amount to ensure that the pipeline operation.
There are various models in the rubber expansion joint series, and the rubber materials used are different according to the medium, including natural rubber, butyl rubber, butyl rubber, nitrile rubber, EPDM rubber, chloroprene rubber, silicone rubber, fluorine rubber and so on. They have the functions of heat resistance, acid resistance, alkali resistance, corrosion resistance, wear resistance, oil resistance and so on. Therefore, it is key to raise and transport source water and wastewater, water supply and drainage and cooling circulating water of thermal power station, industry, condensate, pipeline transportation of chemical manufacturing industry's compounds, petrochemical industry's, diluent and flexible connection between long and short route pipes in other fields.
