The outlet of the safety valve is flowing back to the inlet of the safety valve! The safety valve on the equipment has no issues~~~? ?

No problem – why can it leak from the outlet to the inlet?
I don’t understand what the original poster means; please provide more details.
Is it possible to go from the outlet to the inlet? Is there a problem with the pipeline...
Under normal conditions, the pressure at the outlet of a safety valve is much lower than the pressure at its inlet; in addition, the outlet piping for safety valves connected to common media is mostly directly vented. Where did the original poster get the idea that the outlet of the safety valve could flow back to its inlet?
The outlet pressure of a safety valve is lower than the inlet pressure – how is that possible?
The pressure at the outlet of the safety valve is much lower than the pressure at its inlet; it is generally vented directly or connected to a vent line. Please describe it in more detail
Is it related to temperature? Just like a steam safety valve, liquid reflux occurs after condensation.
There is a safety valve on the bottom outlet pipeline for liquid ethylene; a burst disc is located before the inlet of this safety valve. At present, the outlet of the safety valve is covered with ice, and there is material inside the outlet pipeline – but how could it flow back to the inlet of the safety valve? Is it a leak in the sealing surface of the safety valve?
I can’t understand it; it seems like the original poster didn’t organize their words properly and didn’t explain things clearly. Maybe they should upload a picture instead?
