This paper introduced control valve selection and its application based on the theory of flow characteristic, pressure drop, flashing, cavitation and noise.
针对调节阀的流量特性、压降、闪蒸、气蚀及噪音等问题介绍了调节阀在选型和应用中的要点。
Metal pressure can drop several atmospheres below the metal vapor pressure in areas of very fast flow, possibly causing cavitation and erosion.
金属制的压力能在非常快速流量的面积中在金属制的蒸汽压力下面放弃一些大气，可能地引起涡轮真空和冲蚀。
Under part-load conditions the use of a dynamic balancing valve is a more effective method to prevent a cavitation as it reduces the pressure drop across a balancing valve.
在部分负荷的条件下，利用动态平衡阀是防止气蚀的有效方法，因为它减少了通过平衡阀的压差。
