Method and system for fluid valve leak detection

摘要

A method detection of leakage through at least one first valve includes admitting an amount of fluid into a first control volume in operable communication with the at least one first valve, thereby pressurizing the first control volume. The first control volume is isolated and a rate of change of pressure in a second control volume in operable communication with the at least one first valve is measured. A system for detecting leakage across at least one first valve includes a first control volume receptive of an amount of fluid and a second control volume in flow communication with the first control volume. At least one first valve is located between the first control volume and the second control volume, and a rate of change in pressure in the second control volume indicates a rate of leakage through the at least one first valve.
