For high-temperature and high-pressure valves, self-sealing is achieved through the combination of a wedge ring and a four-ring design. Could experts explain the principle behind this?

I also need to ask about the material of the bent ring; I only know it’s soft iron, but I’m not aware of the specific grade
Soft iron doughnut rings have now been widely replaced by graphite rings, as soft iron has a relatively high leakage rate.
