Abstract

The effect of back pressure on opening and closing pressure, capacity and tightness of safety valve is analyzed in this paper. According to the analysis and computing, the effect is slight when the back pressure fluctuates. The reasonable design of pilot valve disk and bellow’s sealing areas can reduce the effect of back pressure on the safety valve.
