摘要
分析了控制阀的理想流量特性到工作流量特性的畸变原因及其畸变过程 ,介绍了流量特性的选择步骤及方法 ,并就如何提高控制阀的适应性和控制阀选用中应注意的问题进行了探讨。
The reasons and process of that the ideal flow characteristic evolves to the practical flow characteristic of control valve are analyzed.The selection procedure of the flow catachrestic is introduced.The improving adaptability of control valve and some idea for valve selection is discussed.
