摘要
闸阀在管道输送系统中具有重要作用,但工作中存在断裂、腐蚀、泄漏、磨损等失效情况,严重影响闸阀的使用寿命。为了分析闸阀的失效原理,并提高闸阀的使用寿命,文中以某种闸阀为例,从闸阀的材料、结构、载荷、环境等方面,介绍了主要失效机理和影响因素,并提出相应的改进措施,延长闸阀的使用寿命。结果表明,基于指数分布计算方法对闸阀的使用寿命具有良好的预测能力,通过对闸阀的设计、材料、加工工艺等方面的优化能有效降低闸阀23.68%的故障率,提高闸阀30.85%的寿命,具有良好的优化效果。研究成果可为相关行业技术人员设计制造新的闸阀元件和产品,探索闸阀运维与更换策略提供参考。
Gate valves play an important role in pipeline transportation systems,but there are failure situations such as fracture,corrosion,leakage,wear and tear in the work,which seriously affect the service life of gate valves.In order to analyze the failure principle of gate valves and to improve the service life of gate valves,a certain gate valve is taken as an example,introduces the main failure mechanisms and influencing factors from the aspects of gate valve material,structure,load,environment,etc.,and puts forward the corresponding improvement measures to prolong the service life of gate valves.The results show that the service life of the gate valve based on the exponential distribution calculation method has a good prediction ability,and the optimization of the gate valve design,material and processing technology can effectively reduce the failure rate of the gate valve by 23.68%and improve the service life of the gate valve by 30.85%,which has a good optimization effect.The research results can provide reference for related industry technicians to design and manufacture new gate valve components and products,and explore gate valve operation and maintenance and replacement strategies.
