The principles of pressure increase valves and pressure reduction valves
Thread Content
Same topic; it would be great if you could compare them. Thank you
The pressure boost valve should actually be called a pressure boost limit valve. It is normally closed and connected to the liquid phase side; when the pressure in front of the valve rises above its set value, the valve opens to reduce the pressure. At this point, the pressure behind the valve should be lower than the pressure in front of the valve; it seems to be a process of pressure reduction. A pressure reducing valve should actually be called a pressure reducing and limiting valve. The valve is normally closed and connected to the gas phase side; when the pressure in front of the valve drops below the set value of the valve, it opens, thereby increasing the pressure. At this point, the pressure behind the valve should be higher than the pressure in front of the valve; it seems to be a process of pressurization. This is the basic principle; I’m learning it as I go. As for how valves operate when the pressure exceeds the set value, valves from different brands may be designed differently. I hope friends who know more about valves can discuss this in more depth. There is another question: What is a backpressure regulator? What’s the difference from a pressure relief valve?
Is the pressure before the valve high or the pressure after the valve? As the name implies, it should be the pressure after the valve that is low
It seems the terms for the pressure increase valve and the pressure decrease valve on the second floor are reversed.
