节流式减压阀具有结构简单、操作维护方便等优点，在高压换热器中有很大的应用潜力。通过CFD模拟和实验验证，研究了不同进出口压差、进口面积和节流面积下的排气能力。通过理论分析和模拟计算，得到了放电容量的理论计算公式，并通过实验得到了验证。结果表明，流量的平方与压差成正比，阻力系数与节流面积和法兰面积的倒数成线性关系。该研究为节流减压阀的设计和工程应用奠定了理论基础。
The throttle pressure reducing valve has potential for the high pressure heat exchanger with the advantage of simple structure, easy operation and maintenance. We investigated the discharge capacity under different pressure difference between inlet and outlet, the area of inlet and throttle though CFD simulation and validating experiments. A theoretical formula of the discharge capacity was developed through the theoretical analysis and simulated results and was well proved by the experiments. The results revealed that the square of discharge capacity is positively proportional to the pressure difference, and the drag coefficient has a linear relationship with the throttle area and the reciprocal of flange area. This research establishes the theoretical basis for the designing and engineering application of throttle pressure reducing valve.
