摘　　要：安全阀整定压力是安全阀重要的技术指标之一,整定压力与弹簧松紧的调节有关,排放压力、开启高度及回座压力与调节圈位置有关。但在实际工作中,整定压力也与调节圈位置有关,我们通过一起检验案例,具体分析其产生的原因,并提出相应的防范措施及注意事项。As one of the critical technical indicators of safety valve, set pressure has to do with the tension of the spring. Relieving pressure, lift and reseating pressure are associated with the position of the adjusting ring. However, it is found that the set pressure is also concerned with the position of the adjusting ring. This paper is going to analyzing its causes through some cases and proposing some corresponding preventive measures and precautions.
