摘要
气蚀与噪声问题严重制约着高压差工况下阀门的安全与环保运行。当前,多级降压、抗空化材料等技术虽有一定效果,但普遍存在结构复杂、成本高、被动应对等局限,难以实现气蚀与噪声的协同控制。文章提出一种融合流道优化、材料强化与智能控制的协同设计方法。其创新之处在于通过优化多级降压降噪流道,从源头抑制气蚀初生与噪声产生,应用高性能涂层提升耐冲蚀性,并引入基于实时工况的自适应算法实现智能规避。仿真验证表明,该设计可显著提升气蚀指数并降低噪声20.9 dB(A),证实了其在主动安全控制方面的有效潜力。
Cavitation and noise issues severely constrain the safe and environmentally friendly operation of valves under high differential pressure conditions.Although current technologies such as multi-stage pressure reduction and anti-cavitation materials show certain effects,they generally suffer from limitations like complex structures,high costs,and passive responses,making it difficult to achieve coordinated control of cavitation and noise.To address this,the paper proposes a synergistic design method integrating flow channel optimization,material reinforcement,and intelligent control.Its innovation lies in optimizing multi-stage pressure reduction and noise suppression flow channels to inhibit cavitation inception and noise generation at the source,applying high-performance coatings to enhance erosion resistance,and introducing adaptive algorithms based on real-time operating conditions for intelligent avoidance.Simulation results demonstrate that this design can significantly improve the cavitation index and reduce noise by 20.9 dB(A),confirming its effective potential in active safety control.
