以液化石油气卧式储罐为例,对影响确定安全阀整定压力的相关压力进行了分析,认为确定安全阀整定压力不仅需要考虑容器的工作压力、设计压力以及超压限度,而且尚需考虑安全阀的整定压力允许偏差、排放压力以及密封试验压力,总体上既要满足pwpw,以保证安全阀安全排放后的密封性能。建议相关规程标准应合理完善相关压力之间的关系。
Taking LPG horizontal storage tank as an example, the relevant pressure that affects the setting pressure of safety valve is analyzed. It is considered that to determine the setting pressure of safety valve not only needs to consider the working pressure, design pressure and overpressure limit of the container, but also need to consider Safety valve setting pressure allowable deviation, discharge pressure and seal test pressure, on the whole, it is necessary to meet pw pw, to ensure safety valve safety Emissions after the sealing performance. Suggest relevant standards and procedures should be reasonable to improve the relationship between the pressure.
