The double flange electric ball valve has simple structure, easy assembly and disassembly. What are the advantages of using the double flange electric ball valve in large diameter pipelines? The double flange electric ball valve is a valve that is connected to both pipelines by flanges. When installing pipelines and valves, it can be connected to pipelines. It is limited by a loose combination of short sleeve and flange pipe, which can prevent the pipeline from leakage and damage due to excessive compensation of joint displacement. It is mainly to use loose connection settings of pressure pipeline thrust in the range of allowable absorption of axial displacement and axial displacement. The flange connection, installation, product adjustment and flange connection have expansion joints at both ends of the right angle length. Both sides compress the nuts and bolts uniformly, and then adjust the nut limit so that we can let the stretch amount of the inner pipe be free and flexible, lock the expansion amount, and ensure the safe operation of the pipe.
The double flange electric ball valve has the advantages of simple structure, simple assembly and disassembly, and can compensate the displacement, deflection and dislocation of the pipeline caused by thermal expansion and cold contraction. It is widely used for the connection of pipelines transporting water, oil, gas and granular powder media on ships and land. Its types are limited expansion joints, electric ball valves, split expansion joints, spherical joints, etc. The use of electric ball valve has indeed brought great convenience to the installation and use of pipeline engineering. As far as the medium transmission mode is concerned, the electric ball valve is often used on the pressure bearing pipeline, so there is a high requirement for the sealing performance of its materials. At present, the products often use high-quality sealing rings to solve this problem. However, for the electric ball valve, because it needs to ensure the displacement adjustment caused by the thermal expansion and cold contraction of the pipeline, it is often designed with free expansion and contraction, and the sealing performance of the electric ball valve can still be maintained within its effective expansion and contraction range, but it also brings the strictness of the pipeline and installation requirements connected with it.
The electric ball valve for large-diameter pipeline does not show obvious performance in some small displacement of thermal expansion and cold contraction during normal use. However, when the pipeline is used under special circumstances, the installation position of the electric ball valve for the pipeline is different, and the effect is often different. The service life of the double flange electric ball valve produced by Hengchang Pipeline is relatively long in the same industry. Generally, when the product leaves the factory, our company will spray a layer of high-quality corrosion and wear resistant coating on the outside of the product to protect the pipeline from loss as a surface protective layer. Because of its good wear resistance and corrosion resistance, the double flange electric ball valve product has been repeatedly installed and used by mine pipelines, sewage treatment pipelines, desulfurization and dust removal pipelines, and powder and slurry transportation pipelines.
