| description | The invention discloses an electric control switching damping matching balance valve and a variable amplitude hydraulic system, and belongs to the technical field of hydraulic pressure. The balance valve comprises a pilot damping control channel, one end of the pilot damping control channel is connected with a reverse control port of the balance valve, the other end of the pilot damping control channel is connected with a main valve element control cavity of the balance valve, and the pilot damping control channel is used for increasing or decreasing the opening degree of the balance valve. The principle of electric control switching damping matching control is adopted, the electric control switching unit is additionally arranged, the damping matching type of a control port of the balance valve is changed, different pilot control pressure outputs of the balance valve are achieved, then the opening degree of the balance valve is controlled, and heavy-load low-speed stable falling and light-load high-speed fall |
