工业炼化管道用Q41系列球阀产品故障率数据

评估产品的失效率，判定安全等级，帮助企业改进产品；同时也向客户反馈产品的可靠性数据，增强客户订购我们产品的信心；降低阀门故障率，提升阀门使用寿命；收集产品正常安全运行时间、产品出现故障时间、产品故障次数、失效原因；按照卡方分布的反函数CHIINV(0.05,2*出现的故障总数+2)/2/该系列产品总的运行时长单位h，计算最大的失效率、最小的失效率、平均失效率；根据失效率的值依据IEC61508:2010标准，判定产品安全性等级，失效率10^-7~9.99*10^-7为SIL3；10^-8~9.99*10^-8为SIL4（最安全）

Assess product failure rates, determine safety integrity levels, and help enterprises improve their products; meanwhile, provide customers with product reliability data to enhance their confidence in ordering our products; reduce valve failure rates and extend the service life of valves; collect data including the normal and safe operating time of products, the time when product failures occur, the number of product failures, and the causes of failures; calculate the maximum, minimum, and average failure rates using the formula derived from the inverse chi-square distribution function: CHIINV(0.05, 2*total number of failures + 2) / (2 * total operating hours of the product series, unit: h); determine product safety integrity levels (SIL) based on the failure rate values in accordance with the IEC 61508:2010 standard: the range of 10^-7 to 9.99×10^-7 corresponds to SIL3, and the range of 10^-8 to 9.99×10^-8 corresponds to SIL4 (the safest).
