FIELD: construction. ^ SUBSTANCE: invention relates to hydraulic engineering and can be used primarily in automatic rice irrigation systems. The siphon type hydraulic automatic device consists of a mounting attachment 1 made from a base 2 and pipes rigidly and strictly vertically mounted on it. In pipes 3 there is a crest on which a rod 5, fitted with floats 6, is rigidly attached. The rod is made composite so that, when the submersion layer in the level basin rises, the float does not lead to forced launch of the automatic hydraulic device. Its parts are joined by a threaded sleeve which allows for fast change (within necessary limits) of the length of the rod 5. Rigidity of the entire connection is retained and coaxiality of the rod 5 is observed. In the top part of the crest there is an air admission valve 7. The automatic hydraulic device is connected to level basin water outlet through a sleeve 8, and the water level in the level basin is set by a guide plate 9. ^ EFFECT: use of the automatic hydraulic device increases reliability of operation, rapidness and accuracy of regulation, improves regulation of the submersion layer of the level basin. ^ 3 dwg |
