Analysis of Ball Valve Sealing Pressure Ratio Based on UG Nastran

Rong Song, Zheng Fang

Abstract

According to the calculation of sealing pressure ratio in the ball valves seat sealing surface, Companies generally adopt the experience and the correction formula. The above methods can not reflect the real distribution of sealing pressure ratio in the ball valves seat sealing surface. Through the UG Nastran finite element analysis environment, This study simulates the actual working environment, precise Calculated the real distribution of Sealing pressure ratio, In order to improve the development speed and quality of enterprise's new product.
