为满足鱼雷热动力系统对比例控制器的可变比例调节要求，研究孔板对三转子比例控制器配比比例的影响规律，提出比例控制器耦合孔板与自适应阀的变比例技术，分析孔板与自适应阀的工作原理，对比例控制器加装孔板与自适应阀前后的比例特性进行实验测试。结果表明，比例控制器的氧燃比与冷燃比随流量增大而有所减小且易受入口压力波动影响，但加装孔板后氧燃比与冷燃比变化幅值显著减小。比例控制器耦合自适应阀后冷燃比随流量增大而呈线性增大，同时氧燃比能保持稳定，实现海水比例随运行工况自适应调节。研究成果为鱼雷热动力系统海水变比例调节提供了新的技术方案，也为其工程应用奠定了理论基础。
To address the variable proportional regulation requirements of the proportion controller in torpedo thermal power systems, the influence of orifice plates on the proportional ratio of the tri-rotors proportion controller is investigated. A variable-ratio technology integrating orifice plates with adaptive valves in the proportion controller is proposed. The working principles of the orifice plate and adaptive valve are analyzed, and experimental tests are conducted to evaluate the proportional characteristics before and after their installation. The results demonstrate that the oxygen-fuel ratio and coolant-fuel ratio of the proportion controller decrease slightly with increasing flow rate and are susceptible to inlet pressure fluctuations. However, after installing the orifice plate, the fluctuation amplitudes of these ratios are significantly reduced. When coupled with the adaptive valve, the coolant-fuel ratio increases linearly with flow rate while the oxygen-fuel ratio remains stable, enabling adaptive seawater proportion regulation under varying operational conditions. This research provides a novel technical solution for seawater variable-ratio regulation in torpedo thermal power systems and establishes a theoretical foundation for engineering applications.
