摘要：
FIELD: agriculture.SUBSTANCE: drainage-humidification system comprises a supply 1 and a discharge 2 closed irrigation pipelines interconnected with water distribution executive unit. The water distribution executive unit consists of a vertical pipe 3 mounted on the supply pipeline 1 and the working chamber 4 of pressure with separation from it by the membrane 5 with the rod 6. The water distribution executive unit, the valve gear 19, the container 24 with the float 23, and the rotary valve 44 with the control pipeline are located in series. The cavity 11 of the chamber 4 is connected via the hydraulic pipeline 64 provided with a valve 65, with the switch 27, the shank of which is fixed pivotally with one end of the lever 50 to the rod 22. Movement of the upper lever 50 is limited by the upper stop 58, and the lower lever 51 - by the lower stop 59 above and below the threshold level in the storage container 24. The valve gear 19 is made in the form of a cylinder and has a double piston 20 which is pivotally coupled to the rod 22 of the float actuator. The valve gear 19 is connected to the supply irrigation pipeline 1 through the control pipeline 34 to the valve 35 and is respectively connected to the manifold 42 with drains-humidifiers 43. The storage container 24 with a siphon 28 communicates through the rotary valve 44 to the control pipelines 31, 34, respectively, with valves 32, 35 and with the supply pipeline 1.EFFECT: system enables to create closed automated systems in land reclamation, to save water resources, to obtain the necessary productivity of agricultural products with the effective use of land.6 cl, 3 dwgИзобретение относится к сельскому хозяйству, а именно к устройствам для водно-воздушной мелиорации почв, и может найти применение на осушительно-увлажнительных системах.
