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.

因此免费观看国产黄网站在线，上例顯示了4的單級籠式套筒閥可以實(shí)現(xiàn)低噪音91精品国产高潮露脸，盡管閥門內(nèi)件節(jié)流出口速度頭遠(yuǎn)超過480KPa国产一级黄色无码。這就是一些廠家主張的這個(gè)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.
