摘要
介绍了弹簧式安全阀在工况系统中启闭、排放及回座密封的标准和要求。分析了阀门在全开时阀瓣各个断面上的提升力以及介质温度对阀门提升力的影响。给出了弹簧式安全阀的启闭压差结构特性与介质温度相关的推导与计算方法及其结果。
The paper introduces the standards and regulations for spring safety valves of open-close,re- easing and reseat sealing in working system. It analyses the lifting force for the disk on all cross-sec-tions when the valve is in full open position and the influence on the lifting force by medium tempera-ture. It gives the structure characteristic of open-close differential pressure for spring safety valve and derivations related to medium temperature, calculation methods and results.
