摘要
【目的】阀门是水下生产系统的重要组成部分。为了提高阀门的可靠性,需从可靠性设计着手,优化阀门内部流场,来有效降低气蚀对阀门的损坏,即降低振动、减小噪声。【方法】对阀门现有结构进行优化设计,采用计算流体动力学(Computational Fluid Dynamics,CFD)数值模拟对结构优化前后的阀门内部流场进行分析。【结果】经过结构优化后的阀门,其内部流场得到改善,抗气蚀性能得到提高,其稳定性、可靠性、操作性及使用寿命均有所增加。【结论】阀门可靠性的提高应从优化设计开始,必须将可靠性设计理念融入阀门设计过程中,将先进设计手段和技术应用于阀门的数值模拟中,可获得比较理想和精准的优化结果。
[Purposes]Valve is an important part of underwater production system.In order to improve the reliability of the valve,it is necessary to optimize the flow field inside the value from the reliability design to effectively reduce the cavitation damage to the valve,and to reduce vibration and the noise impact.[Methods]The existing structure of the valve was optimized and the internal flow field of the valve was analyzed by using Computational Fluid Dynamics(CFD)numerical simulation.[Findings]After the structure optimization,the internal flow field of the valve was improved,the anti-cavitation performance was improved,and the stability,reliability,operability and service life were enhanced.[Conclusions]The improvement of valve reliability should start from the optimization design.The concept of reliability design must be integrated into the valve design process,and the application of advanced design means and technology to the numerical simulation of the valve can obtain ideal and accurate optimization results.
