摘要
分析了稳压器先导式安全阀系统背压波动情况是否会对安全阀启闭精度、排量以及密封性等性能产生影响。通过分析计算结果显示,系统背压在规定范围内波动时,对安全阀的性能影响较小。但是应注意合理控制先导阀瓣有效密封面积和波纹管有效密封面积的比值,有利于进一步减小系统背压对安全阀性能的影响。
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.
