Thus,theexample above demonstrates that a 4 valve with a singlestagedrilled hole cage can achieve a low noise level despite thefactthat the time exit velocity head is much great than the 480kPalimitations that some valve manufacturers advocate.

因此，上例显示了4的单级笼式套筒阀可以实现低噪音，尽管阀门内件节流出口速度头远超过480KPa。这就是一些厂家主张的这个方法的局限性。

The advantage of CFD numerical simulation especially displays in the development of the new products, it not only can replace theroutine experiment and offer various kinds of flow characteristic parameters by a large margin , It not only can replace conventional experimental substantially provide various flow parameters, and reveals through three-dimensional flow field pattern to optimize design based on detailed. CFD numerical simulation in this text applications will greatly enhance the cage control valve design and the technical level and product quality, reducing cage control valve design and processing cycle, significant cost savings, And optimizes through the flow channel, to reduce fluid flow through the valve of energy loss, improving efficiency in the use of energy have the extremely vital significance.

CFD数值模拟的优势尤其表现在新产品的研制开发中，它不但能大幅度取代常规实验提供各种流动特性参数，而且能通过揭示流场三维分布形态为优化设计提供详细依据；文中所采用CFD方法必将大大提高套筒型调节阀设计的技术含量与产品质量，可缩短调节阀的设计和加工周期，节省大量成本，并且通过流道优化，对降低流体流过调节阀的能量损失，提高能源利用率等具有十分重要的意义。
