FIELD: gas distribution.
SUBSTANCE: invention relates to the field of gas distribution, namely to safety valves intended for protection of gas equipment and networks against overpressure exceeding the permissible limit. Device comprises a valve, an actuation control sensor with a movable element and a load of displacement of the centre of gravity, inlet and outlet pressure gauges, converters, units of comparison, detecting pressure difference, selecting pressure modulation by harmonics, rectifiers, weight adjustment units, adders, setting device of the magnitude of operation when detecting pressure difference, integral counter of operation duration of safety relief valve and transmitter of communication with dispatcher station of gas distribution company.
EFFECT: device provides fixation of valve actuation, determination of total duration of actuation, evaluation of volume of gases released through the valve and check of valve operability at its closing, which increases reliability of equipment operation.
