Regarding the impact of large pressure differences on valves and how to choose them
Thread Content
Good evening. I just read the discussions on Haiyou regarding operating conditions with large pressure differences and their impact on valves; it was very informative. There are a few questions now; I hope Haiyou can give some advice. Thank you. First: Under conditions of high pressure difference, the stress on the valve is high, leading to phenomena such as flashing, cavitation, and erosion. So, when choosing valves, what type of valve should we select that has structural advantages? Second: In our entire thermal power system, where are there conditions with high pressure differences? Thank you to all the forum members who participated in the discussion; I thank you in advance!
