I would like to ask: there should be no negative pressure in pressure vessels, right? Is there a valve that can eliminate negative pressure? Is a vacuum-breaking valve similar to that installed at the top of the tower? Can a breathing valve be used in this situation?

Pressure vessels should always be under positive pressure; how can there be negative pressure?
