Self-pressurizing control method of water conveying and diverting engineering

The present invention is self-pressurizing control technology of water conveying and diverting engineering. By means of the horizontal sections and the upwards bending positive water seal section to form closing down effect naturally, the system is always filled with water; and through the matching between the steep slope section formed by the falling-water enclosed water passage and the water inlet controlling gate valve, the intermittent empty in the steep slope section is used to dissipate energy and to provide different various inner water head. The greater than conveying and diverting flow rate, the greater the dispersed water pressure inside the system and vice versa.
