Description

The invention is intended for irrigation nozzles. The device contains water distribution collectors and perforated pipes connected to them. In order to ensure uniform spattering of fluid and operational reliability under various operating conditions, as well as when the sprinkler is operating on contaminated fluid, the perforated pipes are set obliquely, the perforation holes are made ΙΟΙ 5 ° to the irrigated surface, and the blind ends of the perforated pipes are out .

The invention relates to techniques for splashing liquids and can be used in the energy, chemical, food and other industries.

The aim of the invention is to achieve a uniform spray of fluid, as well as improving the operational reliability of the sprinkler. _ten

FIG. 1 shows a sprinkler, a longitudinal section; in fig. 2 - plan; in fig. 3 - cross-section of perforated pipes. ^one

The sprinkler consists of water distribution collectors and perforated pipes 2, mounted obliquely at an angle of 6-10 ° to the irrigated surface with a rise from the water distribution collectors 1. 20

Holes of perforated pipes 3. are located at an angle (10-15 °) to the horizontal. Perhaps the mutual arrangement of holes in the corridor and checkerboard, order. The blind ends of 4 perforated 25 pipes 2 are made removable, taken out of the apparatus and are located above the water distribution collectors 1.

The sprinkler works as follows: β βθ at a time.

From water distribution collectors G, the liquid enters perforated pipes 2, from where through holes 3, the axes of which are located under

angle 10-15 to the horizontal, flows in the form of inclined jets on the end of the nozzle. The angle of inclination of the holes in the 10-15 provides a sort of gliding. The jets are on the end of the nozzle, which eliminates the direct impact of the jet, spraying and drift of moisture drops by the ascending gas flow. Reducing the angle of inclination below 10 ° creates a stream of liquid directed almost horizontally and onto adjacent perforated pipes.

On the one hand, it will contribute to their wear, on the other - to spatter formation. Tilt angle increase

axes of holes above 15 ° will reduce pro 50

tension arising from the jet hole and increase the energy of its impact on the end of the nozzle. Therefore, in addition, to create a given local irrigation plane, an increase in the number of perforated pipes and irrigation points in them, i.e. such a fill will have prototype drawbacks.

A more uniform distribution of fluid through the holes along the pipe contributes to the installation of perforated pipes with a rise from the water distribution collector.

In the proposed irrigator, the conditions for cleaning the perforated pipes are improved, for which the blind end 4 is perforated. pipe 2 is removable and displayed outside the nozzle apparatus. This allows mechanical cleaning of pipes in working condition without shutting down the apparatus and removing the pipe being cleaned. The fittings for the corresponding shutdown of pipes and their drainage in FIG. 1 not shown.

The slope of the perforated pipes also improves the conditions for cleaning them and putting the device into idle mode. In the latter case, the water flows by gravity from the pipes to the collectors, which eliminates the stagnation of water and the "overgrowing" of the openings with products of organic origin.

In addition, since the proposed device eliminates the direct impact of a jet of water on the end face of the nozzle and the water distribution is organized in the form of a water curtain, the failure of the row of holes will not lead to splashing and will not significantly change the uniformity of the nozzle irrigation.
