Claim 0:
1. A pressure safety valve system for in-line testing and calibration of pressure safety valves (PSV), the system including a first pressure safety valve (PSV) with an inlet, outlet and valve seat working against an adjustable spring which is controlling when said first PSV opens, a first isolation valve at the inlet of the first PSV, a second isolation valve at the outlet of the first PSV, a first bleed valve at the inlet of the first PSV between the first isolation valve and said first PSV, a second bleed valve at the outlet of the first PSV between said first PSV and the second isolation valve, the pressure safety valve system further comprising:
a first Safety Controller (SC) with a processor or controller, data storage unit, and communication means for sending and receiving signals from/to the first SC and an external safety system, the first SC further including a calibration medium input connected to a source of a calibration fluid and a ventilation port,
a first fluid line connecting the first SC to the first bleed valve,
a second fluid line connecting the first SC to the second bleed valve,
wherein the first SC is adapted to connect any of the first and second fluid lines to any of the calibration medium input and the ventilation port or close off any of the fluid lines,
the first SC further including means for regulating and measuring pressure and fluid flow in each fluid line
a first Abnormal Condition Detector (ACD) unit connected to the first PSV for detecting leak sounds,
second and third ACD units connected to each isolation valve, for detecting sound and valve position,
fourth and fifth ACD units connected to each bleed valve, for detecting sound, valve position and flow, and
wherein the ACD units are connected to the first SC for transferring leak and position data to the first SC.
