What is the function of an excess flow valve connected to the burst disc and leading to the atmosphere?

I would appreciate some guidance from those who know more O(∩_∩)O Thank you
Reduce pressure to ensure that the flow rate downstream of the main relief valve does not change significantly depending on pressure levels； Second, it is to ensure that the predetermined flow rate of the vent pipe remains basically unchanged, or to limit any excessive flow rates within the predetermined range. Personal opinion
With the line for this small Excess Flow Valve being only 0.25 inches, how can it be ensured?
1. The atmosphere to which gas is discharged should be ATM; a safe location is not necessarily the atmosphere, and it’s uncertain whether a receiving container is needed. If such a container is present, it is necessary to protect the container at the back. 2. It is important to prevent sudden pressure release, as this could cause materials, especially liquids or semi-solid materials, to flow into the discharge pipe and cause blockages. 3. Providing time for the system’s instrumentation and control systems to respond and make adjustments can help reduce material waste
The rupture disc and the pipe are also joined together by flanges, right? Why is there pressure between the rupture disc and the safety valve? Isn’t it just the normal pressure during installation?
Thanks, bro. I think the PDF provided by the guy on floor 5 is also quite good
These are the manufacturer’s data, provided here for your reference; additionally, an explanation (such as a texture) can be found.
I get it roughly. Thanks, man
Should the valve for NO be NC?
It’s supposed to be normally open anyway
