Pressure relief valve

Pressure relief valve

Nov-12-20 22:07:07

Can anyone advise me on how to add a pressure relief valve for a fluid system into a model, using the Modelica Standard Library? It will pick up from the pump discharge side and return the flow to the suction side.

Thanks,

Calum

Hello,
it is a bit older post, but I have the same question. Have you found a way to do it?
Many thanks / greetings

I think you can use IncompressibleValve and use input port to set valve opening as pressure changes.

Hello!
Thank you very much for the help. There are different ways to solve it, depending on the requirements. In my case, I solved it with a valve for compressible media and a relative pressure measurement via the valve. The relative pressure measurement then passed the value to a hysteresis and a switch opened or closed the valve. In my case, however, it only worked when I set filterOpening=true for the valve.
