Low-pressure rotating nozzle water sprinkler

Abstract

The invention discloses a low-pressure rotating nozzle water sprinkler. The water sprinkler takes the shape of a disc, and comprises an upper surface and a lower surface, wherein the upper surface has a center part and multiple runner sets; the center part is positioned at the center of the upper surface and protrudes out relative to the edge of the water sprinkler; the runner sets downwards extend to the edge of the water sprinkler from the center part; a water current drops down from the center part and flows along the runner sets to be sprayed out from the water sprinkler; and each of the runner sets comprises a range runner, a driving runner, a U-shaped runner and a brake runner. The range runners are used for broadening the passing range of the water current; the water current flows along the driving runners to drive the water sprinkler to rotate ; the U-shaped runners are used for concentrating the flow of the water current to form jet flows with strong impact force; and the water current flows along the brake runners to reduce the rotating speed of the water sprinkler. The low-pressure rotating nozzle water sprinkler has the advantages of simple structure, excellent damping effect, stable operation, simple operation and installation and reduction of the nozzle manufacturing difficulty and manufacturing cost.

Description

technical field [0001] The invention relates to a sprinkler tray, in particular to a low-pressure rotating sprinkler tray for agricultural irrigation. Background technique [0002] The sprinkler trays of the prior art are mainly divided into two types: fixed type and rotary type. The fixed diffuser is widely used in the industry in the early stage. Although the structure is simple, the radial water distribution is uneven when the nozzle sprays. In addition, the flow channels of the fixed diffuser are mostly straight grooves without a water-passing surface, so it is difficult to obtain better The large spraying radius causes the sprinkler irrigation unit to reduce the nozzle spacing and increase the cost. The rotating diffuser can change the water flow from the vertical direction to the horizontal direction, and use the flow channel to divide one water flow into multiple strands to realize the rotating spray. The early rotating water pans are usually caused by the vertical ...
