A hydraulic control valve, a dual-cylinder extension system and an aerial work engineering machine. The control valve comprises a flow distributing and collecting valve, and control valve body is provided with a first oil opening, a second oil opening and a third oil opening. A first oil opening, a second oil opening and a third oil opening of said flow distributing and collecting valve are respectively communicated with the first oil opening, the second oil opening and the third oil opening of the valve body. The control valve has two working states, wherein, in the first working state, the oil path between the second oil opening and the third oil opening of the valve body is blocked; and in the second working state, the oil path between the second oil opening and the third oil opening of the valve body is opened.
