摘要：AbstractThis paper introduces a simplified mechanical model of pressure relief valves extended by a downstream pipe. The distributed parameter model of the system is presented and transformed into a system of neutral delay differential equations. It is shown that the time delay is proportional to the length of the downstream pipe. The analytical investigation of the system proves the stabilizing effect of the pipe length, which is relevant in the safe operation of these valves.
