I would like to ask about the names of the pipe fittings in the picture and their functions in the piping system

There are currently 4 images available. 001 refers to the valve at the outlet pipe interface directly below a horizontal storage tank on-site (the medium inside the tank is unknown). Is this valve a Y-type globe valve, and does it have good sealing performance? 002 is an MTBE floating roof tank; what is the purpose of the pipelines that run along the tank wall in the diagram? 003 represents the outlet section of the nitrogen buffer tank. What is the object located near the tank wall in 003, and what is its function? 004 is its close-up photo.
The first one is for sampling, and the second one is for pressurization
The last one should be a check valve, allowing fluid to flow only in the direction indicated by the arrow
1 Is it used for sampling or for draining liquid during maintenance? Is 2 used for purging, and is 3 a one-way valve?
Figure 1: Sampling from the bottom or draining it completely; Figure 2: The pipelines in the internal floating roof tank are used for oil filling; Figure 3: Butterfly check valve
1. Y-type valves can only be installed in one direction; they experience considerable resistance when closed, so their sealing performance is likely to be poor. 2. The yellow ones are likely nitrogen pipelines; as for those silver-gray ones, it’s not clear whether they are used for instrument air or air for pneumatic purposes. 3. Wafer-type check valve~~
It’s called a Y-type stop valve~~ What medium does the silver-gray pipeline carry?
The sealing should be good, as a manual valve has been installed for sampling purposes
