expansion valve
Dear guys,
Suppose that we have two containers, One of them empty and the other one has for example 500 PSI pressure.
We link them via a thermostatic expansion valve or via capillary tube or orifice.
I have a simple question, After couple of hours pressure of both of containers should be same or not ?
1 – If after a while pressure of these two containers would be same :
If this is true, How a regulator of capsule of nitrogen works that drop pressure 120 bar to for example 200 PSI ?
My friend told me structure of that is such as expansion valve contains a cone needle.
2 – If after a while pressure of these containers would not be same :
If it is true, When we turn a system off, How pressure of two side of low and high pressure reach to each other after a couple of hours ?
Thanks for participating to this material.
