摘要/Abstract

摘要： 阀门的流阻系数和开启力是评价阀门性能的最重要参数，针对先导式通海阀内流道降噪优化前后对于这两个参数的影响，运用计算流体力学CFX软件对不同外部工作压力及开度下的两种流阻系数进行仿真与试验分析。分析结果表明：在阀门具有较小开度及完全开启时，优化后流道流阻系数小于原流道。同时，对有先导孔和无先导孔的通海阀用CFX软件在不同开度下进行静分析，并依据实际阀杆轴向力影响面确定了轴向力提取面组，提取两种情况下、不同位置阀杆轴向力。分析结果表明：先导孔有助于减小阀门的开阀力，且有先导孔时，阀门的最大开阀力仅为无先导孔时的1/2.通过试验对仿真得到的开启力进行了验证，仿真与试验结果具有非常好的相符性。

Abstract: The flow resistance coefficient and opening force are the most important parameters for the evaluation of valve performance. In consideration of the influence of noise reduction optimization on the internal flow passage of pilot operated valve, the CFX software is used to simulate and analyze the flow resistance coefficients under different external working pressures and openings. The analysis results show that the flow resistance coefficient of optimized flow passage is less than that of the original flow passage for the valve under low and full openings. The valves with and without pilot hole are also statically analyzed by CFX software under different openings. the surface groups for extracting are determined according to the influence surface of actual valve rod axial force, and the axial forces of valve rod in different positions are obtained. The analysis results indicate that the pilot hole can reduce the opening force, and the maximum opening force of value with pilot hole is an half of that of value without pilot hole. The simulated opening force is validated by experiment, and the experimental result is consistent with the simulation result.
