Abstract

The invention relates to the mechanization of irrigation and can be used on impulse irrigation systems for supplying water or nutrient solution to plants, and can also be used for irrigation of orchards and vineyards. The aim of the invention is to simplify the design. The pulse water outlet consists of a pneumohydroaccumulator 1, an elastic valve 2 having a seal in the lower part, made in the form of a collar 3, and a valve bypass body 4. On the valve body 4 there are a hole 5 and side fittings 6. Longitudinal ribs 7, made on the nipple 8, prevent the elastic valve 2 from moving and serve to increase the flow areas of the water outlet when draining the accumulated volume of water. Hole 9 communicates the cavity between the nipple 8 and the elastic valve 2 with a pressure pipe. The nasal part of the valve 2 is mounted on the nipple 8 with a tension, the size of which is larger than the gap between the valve and the throat of the pneumohydroaccumulator. The implementation of the mechanical seal on the inner surface of the skirt portion of the elastic valve in the form of a collar cuff makes it possible to make the nipple monolithic along with the body. 1 il.

On 4, on the valve body 4 there are a hole 5 and side fittings 6. The longitudinal ribs 7, made on the nipple 8, prevent the elastic valve 2 from moving and serve to increase the outlet sections when draining the accumulated volume of water. Hole 9 communicates the cavity between the nipple 8 and the elastic valve 2 with a pressure pipe. Recycling refers to agriculture and can be used for cyclically supplying water or nutrient solution to plants in greenhouses, as well as for irrigating orchards and vineyards,

The purpose of the invention is to simplify the design.

The drawing shows a pulse outlet.

The impulse outlet consists of a pneumo-idler accumulator 1, an elastic valve 2 having a mechanical seal in the lower part, made in the form of a collar cuff 3, and a valve 4 body 4. The valve body 4 has an opening 5 and side fittings 6. The longitudinal ribs 7, which are made outside on the nipple 8, prevent the elastic valve 2 from moving and serve to increase the water outlet flow sections when draining the accumulated volume of water. Hole 9 communicates the cavity between the nipple 8 and the elastic valve 2 with the discharge pipe. The nosal part of the valve 2 is mounted on the nipple 8 with a tension greater than the gap between the valve and the throat of the pneumohydroaccumulator. In the initial position, the internal cavity of the pneumohydroaccumula 1 torus is in communication with the atmosphere through an annular gap between the elastic valve 2 and the throat.

Pulse outlets works as follows.

The water from the pipeline through the holes 5 and 9 under pressure enters the cavity between the nipple 8 and the elastic valve 2, while the collar 3 seals the elastic valve 2, preventing water flow

The owl part of the valve 2 is mounted on the nipple 8 with a tension, the magnitude of which is larger than the gap between the valve and the mouthpiece. pneumohydro-accumulator. The implementation of the mechanical seal on the inner surface of the skirt portion of the elastic valve in the form of a collar cuff makes it possible to make the nipple monolithic along with the body. 1 il.

From the cavity between the nipple 8 and the valve 2 into the atmosphere, and the latter is inflated, closing the neck of the pneumatic accumulator 1. After the neck has been closed, water is not allowed to drain into the atmosphere, a gap is formed between the bow of the elastic valve 2 and the nipple 8 ), and water along the walls of the nipple enters the pneumohydroaccumulator, compressing air in it.

After filling the pulse outlets in the pipeline network with a special automatic device (command pulse generator), a short-term decrease in pressure is created. At the same time, the pressure in the cavity between the nipple and the elastic valve is reduced. As a consequence, the latter is pressed against the nipple. Now a gap is formed between it, and the neck of the pneumo-accumulator of the torus, and the water accumulated in the pneumohydroaccumulator, under the action of compressed air through the passage channels between the ribs 7 and the side fittings 6 of the housing 4 is drained into the atmosphere. To evenly distribute the water between the plants, perforated tubes or spray nozzles can be connected to the side fittings 6 of the overflow valve body 4.

After splashing the accumulated volume, the elastic valve 2 returns to its original position, together with the cavity of the pneumo-accumulator 1 with the atmosphere. This contributes to the stabilization of splash parameters by maintaining a constant volume of air in the pneumohydroaccumulator.

The implementation of the mechanical seal on the inner surface of the skirt portion of the elastic valve in the form of a collar cuff makes it possible to make the nipple monolithic along with the body.
