摘要/Abstract

摘要： 针对1 200 MPa高压条件下60°锥密封结构的密封性能,使用ANSYS Workbench软件进行仿真分析,得到其密封面的接触压强,并使用不同的材料组合进行1 200 MPa介质载荷条件下的密封性能实验验证。实验使用316L和Cr12MoV材料的“软–硬”组合,以不同的拧紧力矩测试密封效果。结果表明：此材料组合在超高压下能保持良好密封性且无泄漏;拧紧力矩控制在180 N·m以上能实现稳定密封,材料硬度差异在提升密封可靠性和使用寿命上具有重要作用。该结构在高压环境中具有良好应用潜力,适用于超高压密封关键设备。

Abstract: To investigate the sealing performance of a 60° cone seal structure under 1 200 MPa high-pressure condition, simulation analysis was conducted using ANSYS Workbench software to obtain the contact pressure distribution on the sealing surface. Sealing performance experiments were then carried out under a 1 200 MPa oil medium load using different material combinations. The experiment employed a “soft-hard” material combination of 316L and Cr12MoV, with varying tightening torques to test the sealing effect. The results show that this material combination maintains excellent sealing performance and no leakage under ultra-high pressure. A tightening torque greater than 180 N·m is required for stable sealing, and the difference in material hardness plays a significant role in enhancing sealing reliability and service life. This structure demonstrates good application potential in high-pressure environments and is suitable for critical equipment requiring ultra-high pressure sealing.

Key words: ultra-high pressure, 60 degree cone seal, sealing performance, quantitative evaluation
