How to calculate the force exerted by the medium on the valve disc in an axial flow check valve?
Thread Content
Question: How is the force exerted by the medium on the valve disc calculated for axial flow check valves? Has anyone done similar analysis or calculations? I’d appreciate some advice, thank you.
Thanks for sharing; I’m a newcomer, so I’ll take the chance to learn a bit*
I don’t know when, but the word “calculate,” which often appears on forums, has become extremely frequent. The calculation I understand is actually not difficult; what’s hard is finding the conditions needed for the calculation, which is probably the most important aspect. For example, take this axial flow check valve; let’s analyze it to see if it makes sense. The relationship between the force acting on the internal diameter cross-sectional area of the pipe and the pressure in the pipe. That is equivalent to the force exerted on the check valve. The above is an interpretation of the counterfeit version; calculations won’t be possible. See if this is what is meant, for reference only: lol
I also work on axial flow check valves. Are you calculating this for designing springs or for some other purpose? If it is in a fully closed state, then the force is, as mentioned on the first floor, equal to pressure multiplied by the axial projection area. But once it is opened, there is backpressure, so the force should be the pressure difference multiplied by the area; the difficulty lies in the fact that this pressure difference is unknown!
Are you a student at Lanzhou University of Technology? A professor Zhang’s student? It is mainly used for designing springs, and Fluent is used for analysis, but I’m not very good at it. Do you have any materials I can refer to?
