Are there any standard regulations? When multiple safety valves are installed on a device, the opening pressure of one of these valves shall not be greater than the device’s design pressure; the opening pressure of the other safety valves shall not be greater than 1.05 times the device’s design pressure

There are standards; you can take a look at HG 20570

It is also mentioned in GB50160, and it is in bold font, indicating that it is a mandatory standard; for other safety valves, the overpressure shall not exceed 5%. GB150 should also have relevant descriptions.
