全启式安全阀排放能力理论研究

Theoretical Study on the Flowing Capacity of the Full lift Safety Valve

针对可压缩理想流体系统用全启式安全阀的排放能力进行了理论研究。应用理想流体的柏努利方程和质量连续性方程对流量方程进行了推导,进而又对《容规》中对于安全阀排放能力公式进行了验证。针对影响安全阀排放能力的因素进行分析,从而对安全阀的设计提出指导性意见和建议。

The text studied on the flowing capacity of the full lift safety valve which is used to the condensable ideal liquid＇s Bernoulli equation and Mass successional equation,and validated the equation on the flowing capacity of the safety valve in the ＇Supervision Regulation on Safety Technology＇.The factor which worked on the flowing capacity of the safety valve is analyzed at here,so putted forward the directive idea and advice.
