Seeking advice on the installation of a pressure relief valve
Thread Content
As shown in the diagram, the main pipe supplies pressure at 0.6 MPa to the distribution cylinder; from there, the flow moves upward, passing through a steam flow meter and a filter before reaching the pressure reducing valve. This distance is 1.3 meters. May I ask whether, for this 1.3-meter horizontal distance, it is necessary to add a steam-water separator or a drain valve in the water collection well in front of the pressure reducing valve? The current operating condition is to run the machine for 12 hours per day, after which the steam boiler is shut down for 12 hours. Turn it on and off daily for half a year, then stop using it for half a year. Another issue is the volumetric flow rate. The steam pressure is reduced from 0.6 MPa (DN32 pipe) to 0.2 MPa; what diameter should the downstream pipe have? Is DN50 enough? Thank you for the answer
This is a mechanical drawing; it’s a piping elevation view, so it should be drawn according to the process methodology, and the people in it should be removed
The filter should be installed at an angle to prevent water accumulation from causing blockages
