If you need a safety shut-off valve, feel free to message me privately.
The discharge volume of the safety valve must be calculated. On page 20 of GB150, there are the corresponding formulas; you can simply calculate them based on your own situation.
Consider the medium’s viscosity and corrosivity, and calculate the leakage rate first. Under normal conditions, the spring is fully open; slightly more steam is used when it is partially open
