ABSTRACT:
Disclosed is a safety valve system to maintain the flow of fluid through a flow line when the line pressure is less than a predetermined maximum and greater than a predetermined minimum which includes a hydraulically actuated safety valve inserted in the flow line. A control system is adapted to supply control pressure from a pump to the actuator. A pair of sensors are included to sense line pressure and vent the control system to close the safety valve when the line pressure is greater than the predetermined maximum or less than the predetermined minimum. A ratio accumulator is included to maintain the control pressure at a level proportional to the line pressure and to accommodate changes in the volume of control fluid in the control system due to changes in ambient temperature and leakage.
