I have never seen anything like that. I have to agree with Edwin
though and guess at a pressure regulator.
Whatever it is, it is not needed in a simple well system.
Check valve? Being a submersible pump, it has a check valve included
in it to keep the tank from draining back. Thus there is no need for
one up top. Also applies to a top mount pump as the check valve is
normally the foot valve (the entire 'down' pipe and pump has to be
kept full of water)
Pressure regulator? Why? The pressure switch that turns the pump on
and off regulates the system pressure between cut-in/cut-off.
Some sort of 'snifter valve'? Top of the well pumps needed some
method to keep adding air into the tank (pre bladder tank technology).
I also would only touch that mess with a well planned fall back
position, that being the need to pull up enough pipe going down well
to replace the entire thing up top. What the picture shows is a 'non-
repairable mess' without replacing pipe. It also looks like it is on
the verge ot total disintegration.
