The invention discloses an adjustable damping valve. The adjustable damping valve comprises a valve body, a sliding column, a reset spring used for resetting the sliding column, a driving structure used for driving the sliding column to move; the valve body is provided with two oil ports communicated with an oil way; the sliding column is movably arranged in the valve body; a group of throttling holes which are communicated with the two oil ports and have different hole diameters are formed in the valve body and the sliding column. A hydraulic interconnection suspension system comprises a front left hydraulic cylinder, a front right hydraulic cylinder, a rear left hydraulic cylinder and a rear right hydraulic cylinder; the rod cavity of the front left hydraulic cylinder, the rodless cavityof the front right hydraulic cylinder, the rod cavity of the rear left hydraulic cylinder and the rodless cavity of the rear right hydraulic cylinder are connected to form a hydraulic loop a; the rodless cavity of the front left hydraulic cylinder, the rod cavity of the front right hydraulic cylinder, the rodless cavity of the rear left hydraulic cylinder and the rod cavity of the rear right hydraulic cylinder are connected to form a hydraulic loop b; and adjustable damping valves are arranged in the hydraulic loop a and the hydraulic loop b. Damping adjustability can be achieved, and the damping characteristic of the system adapts to the motion state of a whole vehicle.
