1. A simulation device for magnetic closing of flap valve, wherein the simulation device comprises:
a worktable, comprising a driving mechanism for driving the worktable to rotate;
a magnetic pressure maintaining control mechanism, comprising a valve seat, a magnetic valve cover movably connected with one end of the valve seat, and a first magnet for repelling the magnetic valve cover; wherein the valve seat and the first magnet are fixed on the worktable; and
a magnetic valve cover closing control mechanism, comprising a cylinder and a lifting equipment for driving the cylinder to rise and fall; wherein the lifting equipment is fixed on the worktable, and the lifting equipment is located on a same plane as the valve seat; when the cylinder is located in the valve seat, the magnetic valve cover is in an open state, and when the cylinder is separated from the magnetic valve cover, the magnetic valve cover is in a closed state.
