摘　　要：为解决现有截止阀在油气生产运输过程中出现的静电累积安全隐患,设计一种静电导出装置,及时将截止阀瓣上积累的静电导出至阀盖上,从而实现静电消除的目的。通过有限元分析对阀杆盲孔尺寸进行分析优化,并对装置关键部件进行强度验证。搭建低温测试系统,对截止阀进行扭力、泄漏量测试验证,改造后的截止阀满足要求。To address the potential risks of static electricity accumulation of existing globe valves in the process of oil and gas production and transport,a static electricity export device is designed to export the static electricity accumulated on the globe valve disc to the bonnet in time,so as to realize the purpose of eliminating static electricity.Through finite element analysis,the blind hole size of the stem is analyzed and optimized,and the strength of key components of the device is verified.A low-temperature test system is built to test and verify the torque and leakage of the globe valve,and the modified globe valve meets the requirements.
