摘要
分析了内装弹簧平行式闸阀的设计过程,推导出计算弹簧预紧力的方程式,给出了弹簧的选择方法和经过简化的设计计算过程。
A formula of calculation of the spring pretightened force has been deduced from the design of the parallel slide gate valve（DN150,Class2500）With inner spring,which has greatly simplified the complicated calculation and made it easy for the design calculation process.
