安全阀密封比压计算问题的探讨与安全阀设计计算项目建议

摘要

The sealed speciif c pressure is one of the important design calculation items for safety valves. Now most domestic manufacture’s standards are according to the “Utility valves design manual”. It is found with calculate and verification test that the calculation manner of the sealed specific pressure in the “Utility valves design manual” is wrong. At last some suggestions about the design calculation items are given.%安全阀密封比压是安全阀设计计算中一个重要计算项目，目前国内安全阀生产厂家进行设计计算时主要参考《实用阀门设计手册》，经计算与验证试验，发现《实用阀门设计手册》推荐的安全阀密封比压计算方法有误，本文最后对安全阀设计计算项目提出建议。
