Abstract
A Testing System for Safety Relief Valves includes method and apparatus for (1) detecting the 'set point' of a safety relief valve, which set point is defined as an 'equilibrium point' at which a selectively applied pulling force pulling on the closure element plus the force on the closure element due to internal chamber pressure equals the springloaded biasing force, and (2) determining the approximate pulling force at the set point, and (3) determining the set pressure within an acceptable degree of accuracy; wherein the Apparatus of the Testing System is, briefly, comprised of an assembly for generating and monitoring a pulling force on the valve closure element, a pressure transducer for monitoring line pressure in the chamber, and a controller/data acquisition/data processing device for detecting the set point, determining the set point pulling force, and calculating the set pressure, and mechanism for 'tripping' the force generating assembly to stop the generation of pulling force upon detection of the set point and to, alternately, remove or reverse the pulling force.
