How does PVC combo chk valve/ball valve work?

Hello all,

The PVC Combo CHK Valve/Ball Valve seeps water from the thread.
After I unthread the bottom part pointed by the red arrow, I found a round shape object in the middle of the coupling.

It seems to me when I rotate the handle on the top part, it will rotate the bottom rounded object to open/close the pipe.

Does anyone know how this kind of valve works?

Thank you

The ball valve will be a manually turned ball that closes the valve.
There ball is directly inside the valve attached to the handle.

A check valve is a ball that floats or a gate that is hinged.
It can float on top of water to seal or back pressure will force it to seal.
