摘　　要：为了研究蒸汽加热系统疏水阀的流量特性,采用CFD方法对疏水阀内不同相对开度的流场进行了模拟计算,得到了不同相对开度条件下流场中的速度和压力分布,计算得到相对流量并得到流量特性。研究结果表明该疏水调节阀符合等百分比流量特性,符合预期目标。In order to study the flow rate characteristics of steam trap valve in the steam system, CFD method was used to simulate the flow field with different relative opening degrees for the valve. The velocity and pressure distribution in the flow field with different relative opening degrees of the valve were obtained. The relative flow rates were calculated and the flow characteristics were then obtained. The results showed that the steam trap valve conforms to the flow characteristics with constant percentage, from which the expected target was met.
