Abstract
The invention relates to an irrigation and drainage control valve of an irrigation and drainage double-purpose underground water-saving irrigation system. During irrigation, a screw rod handle is rotated to drive a flashboard to move downwards to block a lower gate hole; water for irrigating from high water level passes through an irrigation water inlet, an upper gate hole and a water inlet and a water outlet of a water seepage pipe network to flow into an irrigation and drainage water seepage pipe network; and under the action of soil capillary tubes, the irrigation water seeped from a porous water seepage pipe is lifted to a crop root system layer to be utilized by crops. During drainage, the screw rod handle is rotated to drive the flashboard to move upwards to block an upper gate hole; and high-water-level soil gravity water capable of forming flood seeps into the porous water seepage pipe through the porous water seepage pipe and then flows to a drainage ditch and a drainage channel at low water level through the water inlet and the water outlet of the seepage pipe network, the lower gate hole and a drainage water outlet. The control valve has the characteristics of simple structure, practicability and reliability. The irrigation and drainage double-purpose system has the functions of absorbing water during drought and draining water during flood, ensures stable yields despite drought or excessive rain, can effectively reduce invalid evaporation from the soil surface by the underground irrigation method, and saves water obviously.
