Abstract
Pressure relief valves may be tapped into high-pressure flow lines. The pressure relief valve is normally shut and is adapted to open at a threshold fluid pressure. It comprises a body, a passage, a valve seat, a ball, and a linear actuator. The passage is defined in the body and has a valve inlet and a valve outlet. The valve seat is in the passage. The ball is adapted to engage the valve seat to block flow through the passage. The linear actuator is mounted for linear movement in response to detection of the threshold pressure a from a normally extended position to a retracted position. In the extended position the ball engages the valve seat to close the passage, thereby shutting the valve. In the retracted position the ball can be flushed out of the valve by fluid flowing through the passage, thereby opening the valve.
