Hollywell control valve noise calculation table. There are a few parameters that I don’t understand
Thread Content
As shown, sound power efficiency and Cf (FL)
FL is the recovery coefficient of the valve; generally, valves with a high recovery coefficient have stronger resistance to cavitation
I don’t understand what this is; let someone more professional answer it. I’ve studied it
There are some, but it also has something to do with the manufacturer’s own products. This is a very large data table; the values vary depending on different models of direct-acting valves, different models of rotary valves, and various angles. In fact, this noise isn’t that significant; unless one is a professional who needs to make special selections to address flash vapor erosion, there’s no need to understand it in great detail.
Original poster, could you send me the table you used for calculating noise levels? *yuanzhuxucheng@126.com* Thank you very much; I’d like to learn about it.
Could you send me the attachment? huangweiminle@163.com I’m a valve designer :(
What sources did the original poster’s company use as references to arrive at those results? I have also been researching this noise issue; there are too many domestic studies, and even after compiling the relevant formulas, it still doesn’t seem right
Could the poster please send me their email address? 769142359@qq.com Let’s compare it with our factory’s
