基于阀门填料散逸性试验的API标准研究

摘要

In view of the common reasons of valves leakage, China valves testing standards are introduced. The main problem is lack of specific performance testing standards for valve seal packing, with the relative low requirement for valve seal packing in the existing valves testing standards. API Std 622-2011《Type Testing of Process Valve Packing for Fugitive Emissions》is introduced. The contents are fugitive emissions testing device and procedure, and corrosion testing procedure, and material performance testing procedure, as well as the performance assessing rules for valves seal packing. With the reference of API Std 622-2011,it is useful to perfect valves testing standards and decrease the possibility of valves leakage. Finally, the adopting suggestion for API Std 622-2011 is made.%基于常见的阀门泄漏原因，介绍了阀门试验国内标准，指出存在的主要问题是缺少专门针对阀门密封填料性能试验标准，现有阀门试验标准中对密封填料要求较低。介绍了API Std 622-2011《工艺阀门密封填料逸散性试验规程》，该标准阐述了阀门填料散逸性试验装置和试验程序、腐蚀性试验程序、材料性能试验程序，建立了阀门密封填料性能指标评价准则。借鉴该标准建立阀门填料产品规范，可补充完善阀门试验标准，减少阀门泄漏的可能性。最后提出了API Std 622-2011采标建议。
