DEVICE FOR DETECTION OF LEAKAGES IN FLUID REGULATOR Russian patent published in 2017 - IPC F16K31/12 F16K37/00 F17D5/02 G01M3/28 G05B9/02 

FIELD: machine engineering.

SUBSTANCE: device for detection of leakages in fluid regulators is proposed. The device for detection of leakages in a fluid regulator contains: a plurality of channels, where one channel is designed to take the inject pressure, the other channel is adapted to set off the actuator, and one more channel is connected to the purge port of the cover of the fluid regulator with the possibility of interconnection; the bellows located between the through hole of the fluid regulator and the purge port, substantially preventing the process fluid from flowing into the purge port; a pressure sensor in the purge port; and a processor for comparing the indicated pressure value with the set pressure value or preliminarily measured pressure value for identifying if the pressure value overruns the specified limit.

EFFECT: possibility of improving safety of bellows leakage monitoring by identifying the changes of the pressure in the purge port.
