FIELD: test technology.
SUBSTANCE: invention relates to the field of leak testing of devices and can be used for leakage control of valves of safety valves of pipeline valves. Essence: system of test bench with installed safety valve is filled with air to setting pressure. Air supply is stopped. Measurement process is started and the initial and final pressures are recorded during the measurement time. Prior to measurement, volume of testing stand pipeline and volume of safety valve cavity under the gate are determined. Taking into account the measured values, non-tightness of the gate of the safety valve is calculated.
EFFECT: technical result is increased accuracy and reduced time of leakage measurement of safety valve gate.
