RU2275010C2 - Water outlet for irrigation pipeline of drop irrigation system - Google Patents

Abstract

FIELD: agricultural engineering, in particular, equipment used in surface irrigation systems.

SUBSTANCE: water outlet has casing with discharge opening and fastening member for connecting casing to pipeline. Casing is formed as part of hollow spherical device and is joined to irrigation pipeline opening so as to be partly offset toward discharge opening. Discharge opening is equipped with injector for dripping of droplets onto surface of land plot to be irrigated. Irrigation pipeline, casing and injector are made integral as single part.

EFFECT: uniform dispensing of liquid from irrigation pipeline through water outlet in case irrigation water pressure differences occur within cavity of irrigation pipeline.

Description

The invention relates to agriculture, in particular to drip irrigation systems.

A water outlet to flexible pipelines is known, including an elastic casing installed in the wall of the pipeline and attached to the edges of the water outlet, one of which is bent into the pipeline from the outside, and to quench the energy of the irrigation jet, the elastic casing is made in the shape of a tube (SU, copyright certificate No. 378592. M. cl. E 02 B 13/02, A 01 D 25/02, 1973).

The disadvantages of the known water outlet include limited functionality, complexity of operation, low uniformity of irrigation water delivery.

Known water outlet irrigation pipeline, comprising a housing with a drain hole and a fastener connecting the housing to the pipeline (SU, copyright certificate No. 1501981, M. class. A 01 G 25/02, 1989).

The disadvantages of the known water outlet include limited functionality, significant difficulties in assembling the water outlet and jet water supply, which leads to the formation of a crust on the surface of the soil and increased water consumption.

This water outlet was adopted by us as the closest analogue.

The problem to which the claimed invention is directed is to expand the functionality and increase the operational reliability of drip irrigation systems.

EFFECT: simplified design, economical consumption of irrigation water.

The specified technical result is achieved by the fact that in the known water outlet of the irrigation pipeline, comprising a housing with a drain hole and a fastening element connecting the housing to the pipeline, according to the invention, the housing is made in the form of a part of a hollow ball mating with the hole of the irrigation pipeline and provided with the possibility of partial displacement towards the drain holes, injectors; Irrigation piping, housing and injector are made as a single part.

The invention is illustrated by drawings.

Figure 1 schematically shows a water outlet, a diametrical section of an irrigation pipeline.

In Fig.2 is a section aa in Fig.1, a horizontal diametrical section of the pipeline with a view in plan of water outlets.

Figure 3 is a view A in figure 1.

Figure 4 is a view In figure 1.

Information confirming the possibility of implementing the claimed invention are as follows.

The water outlet of the irrigation pipe of the drip irrigation system includes an elastic flexible pipe 1, a housing 2 made in the form of a part of a hollow ball, an injector 3, a water outlet 4, a water channel 5 and a drain hole 6 (see Fig. 1). The housing 2 is connected to the pipeline 1 by a flexible element 7. The irrigation pipeline 1, the housing 2, the injector 3, the water outlet 4 and the channel of the watercourse 5 are made as a single part.

The water outlet of the irrigation pipeline works as follows.

When the water flow moves through the pipeline 1, the capacity of the hollow ball of the casing 2 is filled with irrigation water and partially increases the gap between the casing 2 and the pipeline 1, forming a drain hole 6. In the formed gap, water enters the channel of the watercourse 5 and enters the soil under the action of gravity. After draining the water from the casing 2, the elastic flexible element 7 closes the drain hole 6 and the flow of water stops until the casing 2 is refilled. Thus, the casing 2 is periodically opened and provides a portioned water supply to the soil. The injector 3 and the channel of the watercourse 5 provide moisture to the root layer of the soil. This prevents the formation of soil crust, reduces the consumption of irrigation water and increases crop yields. The design of the water outlet will provide high operational reliability.
