"when the velocity is increased so, the pressure is decreased"
This conclusion is only valid in steady flows, with constant density and negligible mass and viscous forces. I do not think that your case is well-suited to these assumptions.
In order to help you, it would be interesting to see a general picture of the problem with the boundary conditions, as well as screenshots of the mesh and contours of some variables.
