What happens to a backpressure-type steam trap when there is no backpressure?

What happens to a backpressure-type steam trap when there is no backpressure? For example, a sudden large-scale leak in the condensate line can result in an extremely low back pressure. At this point, will the trap close, preventing both air and water from escaping, or will a large amount of steam flow into the condensate line? Please let me know, thank you!
Backpressure steam trap, with outlet drainage pressure lower than inlet pressure； There is a significant leak in the condensate line downstream of the desuperheater; the pressure is below the required design backpressure, and as a result steam leaks out or some steam is generated due to depressurization flashing in that section ； There is a leak on the inlet side of the trap, preventing it from reaching the required drainage pressure; as a result, the trap stops discharging steam and water. :)
Thank you to this friend for the reply. But according to my theory, when there is no back pressure or the back pressure is extremely low, steam will leak towards the condensate line. So what is the steam leakage rate? Or is it still the back pressure that determines the amount of steam leakage? The higher the back pressure, the less steam leaks, and vice versa (provided that the back pressure is lower than the normal operating pressure of the trap)? Is that how it should be understood?
No problem. . . . . . . . .
