Regulating valve pressure drop
Thread Content
The plant’s pipeline system has steam at 2.5 MPa, while the design specifications call for steam at 1.3 MPa. How can the steam at 2.5 MPa be reduced to 1.3 MPa? Can the pressure be reduced through a flow control valve?
It’s not a flow control valve; a pressure reducing valve will suffice.
The pressure can be reduced using a flow control valve, but in this case the variable being controlled is pressure rather than flow.
Reducing pressure causes a drop in temperature, and the issue of condensate must be taken into account
I think it’s better to use the previous mixer – by injecting demineralized water into the steam, more steam can be produced. All that’s needed is an additional control valve; how great is that?
Personally, I suggest using a self-acting pressure relief valve
Either a pressure relief valve or a control valve will work. But if high stability of pressure is required, it is best to use a control valve
Agree with XD on the 4th floor – pressure reduction causes a temperature drop. For other gases, it may not necessarily be the biggest problem, but that’s not necessarily the case for steam
