The invention relates to agriculture and can be used for drip irrigation method.

Known dropper comprising a housing with inlet and outlet nozzles and installed a float valve element included in the input pipe, in which the purpose of self-cleaning drip and simplify its design case and the float is made in the form of a concentric set of cones, while the float is provided with a second locking element within the outlet, and has on the surface a spiral ledge to regulate flow second shut-off element is made removable (SU inventor's certificate No. 704540, CL 01 And G 25/02, 1979).

The disadvantages described droppers include low operational reliability and a high degree of purification of irrigation water from suspended solids and microorganisms.

Also known dropper, including mounted in the hole of the humidifier housing and mounted therein regulatory element in which to improve the reliability of the stabilization of the flow regulating element is designed in the form attached at one end to the wall of the housing of the hard walls not reaching the opposite wall, and a flexible combs, the teeth of which are placed between the rigid walls and also do not reach the wall of the body (SU inventor's certificate No. 908284, CL And 0 G 25/02, 1982).

Described the drip is operable with a high degree of constancy of the water pressure in the power network droppers and are prone to clogging by sediment.

The closest analogue to the claimed object is the drip containing lid with inlet fitting installed on the irrigation pipeline, and the outlet in the lower part of the body in which to improve the reliability and efficiency it has installed in the housing coaxially with the inlet fitting compensation chamber in the upper part of which is fixed a hollow corrugated flexible element having the shape of a truncated cone, with the cavity of the compensation chamber is in communication with the irrigation pipeline through the channel and fitting, and the upper base is made rigid and provided with a sealing element in contact with the bore of the inlet fitting, the edges of which are made with an internal chamfer (The SU inventor's certificate No. 1648289, CL 01 And G 25/02, 1991).

Described dropper has a low reliability.

The essence of the claimed invention.

Task to be solved by the claimed invention is directed, - improving the reliability of drip irrigation systems.

The technical result - the simplification of the structure.

This technical result is achieved by the fact that in isostatically, including the cover from the inlet fitting installed on the irrigation pipeline, building and fixed dosing element, the discharge from the outlet fitting at the bottom of the housing cover according to the invention with the inlet fitting and outlet with the outlet fitting provided with a socket set are arranged in the housing, the regulatory element is designed as a flexible elastic membrane with a metering hole and freely mounted between the float, when this membrane is fixed in the housing by a threaded cap and a discharge outlet, the diameter of the metering holes of the membrane under a cover larger than the diameter of the metering holes of the membrane above the culvert.

The invention is illustrated in the drawing, which schematically on an enlarged scale shows a diametrical section of the dropper.

The dropper includes a cover 1, case 2, the regulating element 3 and the outlet 4. Cover 1 with the inlet fitting 5 is installed on the irrigation pipeline. Outlet 4 outlet truboprovoda 6 is mounted in the lower part of the housing 2. Cover 1 with the inlet fitting 5 and the outlet 4 outlet truboprovoda 6 provided with sockets 7 and 8. The sockets 7 and 8 in the housing 2 is installed opposite. The regulating element 3 is designed in the form of a flexible elastic membrane 9 and 10 with dosing orifices 11 and 12 and is freely mounted between the float 13 of the Membrane 9 and 10 are fixed in the housing 2 screw cover 1 and a discharge outlet 4. The diameter of the metering holes 11 of the membrane 9 with the lid 1 is larger than the diameter of the metering orifices 12 of the diaphragm 10 above the outlet 4. The number of holes 11 on the membrane 9-6, and their diameter is equal to 2...3 mm Number of holes 12 on the membrane 10-6, and their diameter is equal to 1...1.5 mm Float 13 is made of tube density is 0.22 t/m3. The angle at the vertex of the cones of the sockets 7 and 8 are more than 120°.

The dropper works as follows.

Water from the irrigation pipe under pressure through the inlet fitting 5 in the cover 1 is fed into the cavity between the membrane 9 and the cover 1. Due to socket 7 sharply decreases the water pressure, but the hydraulic impact of the jet of water, the membrane 9 is unbent down and through the float 13 regulatory element 3 acts on the membrane 10. The membrane 10 covers the socket 8 and prevents the ingress of water in the discharge pipe 6.

When filling namebrands cavity cover 1 and the membrane 9 water through the holes at a lower pressure enters the cavity of the housing 2, limited membranes 9 and 10. When completing this cavities in the water floats the float 13, which presses on the diaphragm 9 from the bottom aligned with the water pressure above and below the membrane 9. Moving membrane 9 up leads to overlapping of the socket 7, limiting the access of water into the cavity between the cover 1 and the membrane 9. Then the water through the holes 12 in the membrane 10 fills p is membranous the cavity between the outlet 4 and the membrane 10. When the alignment of the water pressure above and below the membrane 10 it through the funnel 8 flows into the discharge pipe 6. Next irrigation water comes to the surface of irrigated land to the roots of S. agricultural crops.

Changes in water pressure in the irrigation pipeline through the membranes 9 and 10 and the float 13 in the housing 2 droppers leveled and evenly given to the surface of irrigated land. Design dropper ensures high operational reliability.
