微启弹簧载荷式安全阀试验介质研究

Research on the low-lift spring safety valve to different testing medium

介绍了微启弹簧载荷式安全阀用于气体或液体介质的工作特性和选用原则,分析了微启弹簧载荷式安全阀结构及气体或液体介质对阀门动作性能和排量系数的影响,给出了以不同试验介质得出的测试数据和针对阀门型式合理选用试验介质的理论依据。

The working characteristics and selection principles of the spring-loaded low-lift safety valve for gas or liquid medium are introduced,the influence of the structure of the spring-loaded low-lift safety valve and the gas or liquid medium on the operating performance and displacement coefficient of the valve is analyzed,the test data obtained from different test media and the theoretical basis of selecting test media reasonably for valve type are given.
