The invention discloses a water dropper for drip irrigation, which is characterized in that the water dropper is provided with an outer cylindrical cavity (1) and an inner cylindrical cavity (2) which are coaxially arranged, wherein a water pipe (5) is arranged on an end plate (1-1) of the outer cavity (1); a buffer head (6) is sheathed at the lower end of the water pipe (5); a supporting plate (2-1) is radically extended on the outer wall of the lower part of the inner cavity (2); a sewage collection cover (7) is arranged at the lower end of the inner cavity (2); inner rectangular teeth (4) are arranged on the inner wall of the outer cavity (1); outer rectangular teeth (3) are arranged on the outer wall of the inner cavity (2); the upper end and the lower end of at least one from the outer rectangular teeth (3) or the inner rectangular teeth (4) are respectively and tightly contacted with the end plate (1-1) and the supporting plate (2-1); for the two neighboring teeth in the rest outer rectangular teeth (3) and rectangle inner teeth (4), the upper part of one tooth is provided with a gap and the lower part of another tooth is provided with a gap; and a labyrinth runner (11) is formed by the gap and the clearances between the side surfaces of the outer rectangular teeth (3) and inner rectangular teeth (4).
Description
technical field [0001] The invention relates to an irrigation appliance, in particular to a dripper for drip irrigation. Background technique [0002] The reuse of sewage is of great significance to solving the problems of water resources and sewage pollution, and has been widely promoted around the world. Because drip irrigation has the advantage of saving water, it is an important irrigation method and a key development direction in the field of sewage irrigation. Dripper is an important part of drip irrigation technology, and its energy dissipation and anti-clogging performance are key technical indicators. Especially for sewage containing a large amount of impurities, the anti-clogging performance of dripper is more important. [0003] For a long time, most of the flow channels of dripper products adopt a labyrinth structure, which has a good energy dissipation effect. However, due to the small cross-section of the flow channel and impurities in the water, the labyrinth...
