I mean, think of it like a pressure valve.

我的意思是，把它想象成一个压力阀。

Sea vents are like pressure valves releasing growing tension from chambers of molten rock beneath the crust.

从地壳下面的熔岩室不断释放能量但是 如果压力过大 岩浆就会到达喷发点。

Furthermore, they can serve as societal pressure valves, giving voice to anxieties that may not find expression in mainstream discourse.

此外，它们还可以充当社会压力阀，表达主流话语中可能无法表达的焦虑。
