摘要

Abstract

A numerical method was applied to characterize the cause of leakage of high-pressure double disc check valve. It was found that the leakage of high-pressure double disc check valve was caused by the plastic deformation of valve disc and valve seat. This was consistent with the fact that the valve did not leak after the first-round pressure test but leaked after the second-round pressure test.
