VALVE TESTING SYSTEM Russian patent published in 2023 - IPC F16K37/00 G01M3/28 

FIELD: chemical plants; offshore hydrocarbon production platforms; shipboard treatment plants.

SUBSTANCE: described is a portable system (100) for testing a valve (3) in a process plant. An inlet connector (102) and/or an outlet connector (104) provide fluid contact with a respective inlet check valve (2) or outlet check valve (4). The summation method makes it possible to detect and quantify a small leak (20, 40) through each shut-off valve (2, 4) during testing or certification of the valve (3). The laptop computer (110) runs the controller for automatic testing or certification. The controller (120) supports branching into separate diagnostic procedures depending on the measurement results from the sensors (122, 124). The security system (130) ensures the reliability and confidentiality of measurement data and facilitates certification. Areas of use include chemical plants, offshore hydrocarbon production platforms and shipboard treatment plants.

EFFECT: reliability and confidentiality of measurement data and facilitates certification.
