Valves are widely used in various working conditions for their flow control functions, and the cavitation inside valves has been investigated owing to its harm to the valve itself and the connecting downstream parts. This paper presents a comprehensive review of the progress that has been achieved in the past years about cavitation in valves including both mechanical heart valves and control valves. The review is divided in the following parts, namely the location where there is a high possibility of the occurrence of cavitation, the parameters that affect cavitation intensity, and the methods to minimize cavitation intensity. It should be noticed that although simulation has been widely used, advanced experiments are still needed in order to obtain accurate analysis of cavitation in valves and the cavitation model still needs to be improved.

阀门气蚀的综合综述：机械心脏瓣膜和控制阀

阀门因其流量控制功能而在各种工作条件下得到广泛使用，并且由于其对阀门本身和下游连接部件的危害，已经对阀门内部的气穴现象进行了研究。本文全面回顾了近年来在包括机械心脏瓣膜和控制瓣膜在内的瓣膜中的气穴现象所取得的进展。综述分为以下几部分，即极有可能发生空化的位置，影响空化强度的参数以及使空化强度最小化的方法。应当注意，尽管模拟已被广泛使用，但仍需要进行高级实验才能获得对阀门中气穴现象的准确分析，并且仍然需要改进气穴模型。
