FIELD: agriculture.
SUBSTANCE: water outlet includes the gate which opens inside the pipeline. The gate is a traveling valve, which consists of cone shut-off head located in the body. The cone shut-off head is connected to the cylindrical body with an elastic perforated diaphragm which is set inside of the pipeline above the water outlet port and blocks its lead-in edge. The calibrated orifices are made full-circle of the bug diameter of the valve cylindrical body in the diaphragm, the total flow area of the calibrated orifices corresponds to preset flow through the water outlet. The cone shut-off head is fixed with the orbicular retainer outside of the body. The water outlet port in the pipeline has the cone shape.
EFFECT: providing preset flow along the whole pipeline.
