Description

The invention relates to agriculture, in particular to land reclamation,. and is intended for irrigation of agricultural crops by the drip method.

The purpose of the invention is to increase the washing efficiency.

On fis, 1 the dropper is presented, a general view; FIG. 2 is a section A-A in FIG. 1,

The dropper includes a lid I (see Fig. 1) with an inlet nozzle 2. The lid 1 is attached to the case 3, the inside of which is placed an elastic, elongated membrane 4. The base 5 of the case 3 is also domed and has a shaft 6 at the top. The rod 6 is placed in run-. On the periphery, the MeM6paiia 4 is provided with a corrugated rim 7 fixed to the housing 3. Water-based ribs 8 are formed along the forming base of the bases 5, dividers 9 are made between the ribs of the watersheds 8 Fig. 2) of the flow, which are also made in the form of fins, their length is 0.5-0.75 of the length of the fins 8. The dividing flow of the ribs 8 is 8 separate from the separators 9 Additionally, in the base 5 there is an annular rim 10 (cm, fig. 1) for placing therein ofrirovannogo rim holes 7 and outlet fittings 11,

The dropper works in a similar way.

Water from the discharge pipe through the inlet fitting 2 enters the cavity between the cap and the membrane 4. After filling it, water through the opening at the top of the dome-shaped membrane 4 flows to the surface of the dome-shaped base 5, the surface of the base, washing it. With an increase in pressure, the membrane 4 presses

5 to the fins 8, forming the water conducting channel. From this moment on, the operating mode of the flow of water is choked. In this case, the channels formed by the flow dividers 9,

0 muffled because their length is smaller. the length of the edge-conduits 8, With further pressure head outside the operating range, the water consumption drops sharply.

When the pressure drops in the network, the membrane 4 under the action of the elastic forces of the corrugated rim 7 begins to lift. When the pressure drops to. insufficient values for pressing the membrane 4 to the dome-shaped base 5, between them a gap is formed, with & which is intensively supplied by water, washing the surface of the dome-shaped base 5. At the same time moving the membrane 4 relative to the rod 6 ensures the cleaning of the hole.
