The Strength and Sealing Analysis of High Pressure Ball Valve for Natural Gas
Ball valve with large-diameter, high-pressure, corrosion-resistant and high-reliability has been used for West-East Pipeline. In order to improve the product reliability and safety, reduce the product consumption and costs, and shorten the product design cycles, finite element analysis(FEA) has been used to simulate the strength and sealing analysis process which can’t be proceed on site or in the real environment. The results illustrate the stress and loading distributions as well as pre-identify the potential problems, which show that the strength and sealing of the valve in three different conditions is very safe.
