改善弹簧直接作用式安全阀密封特性的实验研究

Experiment on Improving Seal Propertives of Spring Loaded Safety Valve

利用力的平衡关系设计的平衡机构，可使弹簧直接作用式安全阀的密封比压力变成系统工作压力的阶跃函数，为克服弹簧直接作用武安全阀的超前泄漏提供了有利条件．本文所介绍的实验验证了平衡关系对改善弹簧直接作用式安全阀密封特性的作用．

The mechanism designed based on balance relationship between force can make the sealing pressure of spring loaded safety valve becomes bound funtion of the system pressure.This is profitable for soluting the leakage of safety valve.The experiment discussed in this paper proved balance relationship to be an efficient method to improve the sealed propertives of the safety valve.
