Known drip irrigation system for greenhouse containing a pump for supplying water under operating pressure from a source (pond, water tank), podgornik plants, mineral fertilizers, filter gauges, trunk, distribution and irrigation pipes, connecting fittings, valves and remote control valves, drippers "Vodpolimer-3 and guide tubes (brochure VDNH USSR. Drip irrigation system for greenhouse /Editors: R. T. Balode, J. A. Karklis, A. B. maltster, H. P. SEPs. Jelgava (Latvian SSR), 1987, S. 4).

The disadvantages of this system include low operational reliability droppers "Vodpolimer-3 and the high cost of the whole system compared to equivalents in foreign countries.

Known dropper, including humidifiers, the injectors with hydraulic resistances and holes underneath them (SU authorship 545305, CL 01 And G 25/02, 1977).

A disadvantage of the known drip is the complexity Konstruktsiya collapsible chamber with injector and fitting (SU, copyright certificate 1109901, class A 01 G 25/02, 1984).

The disadvantage of this dropper is the impossibility of its installation in the soil near the stem, vine or stem of the plants or plants and, as a consequence, the spreading of water over the soil surface irrigated area, scum formation, preventing access of atmospheric air to the plant roots.

The closest object to the requested dropper in its essence, and the number of essential features is the drip, including a detachable cover with inlet membrane housing with the nozzle and the injector, and the injector is made in the form of a pin with ribs converging to the tip of the pin, and the camera is formed by a detachable cover and a case fitted with a calibrated hole (see patent FR 267159, M CL5A 01 G 25/02. Declared 10.05.1991; Application 9105978; publ. 13.11.1992). This drip adopted for the nearest equivalent.

The disadvantages of this dropper include low operational reliability, limited performance, high demands on the quality of irrigation water and to the working pressure range in irrigation pipelines.

The problem to which the invention is directed, enhanced operational reliability.0.5 l/h

This technical result is achieved by the fact that in the known drip, including split housing with a nozzle in the upper part and the lower part with the injector in the form of a pin with ribs converging to the tip of the pin in the plane of the connector body between its basic parts posted membrane, forming namebrand cavity, podobrannyy cavity and around the ring cavity, while podobrannaya cavity connected to a storage capacity of the injector of the orifice according to the invention the membrane is made of a multilayer, the upper and lower layers formed in the form of different-sized flat rings, and between them is placed an elastic porous permeable material, when connecting podobrannyy cavity with a cumulative capacity of the calibrated hole is made in the form of a cone widening towards the lower flat ring membrane, and slice the supporting part of the body is above the upper edge of the cone with the orifice plug of the hull is equipped with speed clips in the form of a mating annular dies, and the supporting part of the housing, between which is placed a membrane channels.

The invention is illustrated in the drawing, where sobti and in the lower part with the injector 3 in the form of a pin 4 with the ribs 5. Ribs go to the tip of the pin 4. In the plane of the connector housing 1 between the supporting parts 6 and 7 posted by the membrane 8. The membrane 8 is made of a multilayer. The upper layer 9 and the bottom layer 10 is formed in the form of different-sized flat rings. The material of flat rings of the upper layer 9 and the lower layer 10 is a polyvinylchloride resin composite fillings, are made according to a recipe P4. The thickness of each layer 9 (10) does not exceed 0,6...0,7 mm Material of the middle layer of the membrane 8 is foam rubber with oriented cells.

As the middle layer of the membrane 8 can be used any elastic porous permeable material.

The membrane 8 in the cavity of the housing 1 forms namebrand cavity 11, the limited space of the fitting 2 in the upper part of the body 1, the ring supporting part 6 and the upper layer 9 of the membrane 8, podobrannyy cavity 12, limited space in the bottom of the housing 1, the ring supporting part 7 and the lower layer 10 of the membrane 8, and the annular cavity 13 formed by the rings of bearing parts 6 and 7, the outer cylindrical surface of the membrane 8 and the inner surface of the separable parts of the housing 1. Podobrannaya cavity 12 is connected with a storage capacity of 14 injector 3 the orifice 15.

Seedier 16, extending in the direction of the ring of the lower layer 10 of the membrane 8. Circular slice of the support part 7 of the housing 1 is made higher than the upper edge 17 of the cone 16 with a calibrated orifice 15.

Detachable part of the housing 1 is equipped with manual clamps 18 and 19 on the outer and inner surfaces of the housing parts 1, made in the form of mating annular die with bumps and hollows.

The supporting parts 6 and 7 of the housing 1, between which is placed the different-sized rings of layers 9 and 10 of the membrane 8, have power channels 20 and 21. The channels 20 and 21 are made floating in the diametrical planes of the rings of bearing parts 6 and 7 of the housing 1. Channels 21 communicated constantly with the annular cavity 13 and podobrannoj cavity 12. The channels 20 are combined namebrand cavity 11 with the annular cavity 13 only when pressure or hydraulic shock.

A calibrated orifice 15 is symmetrical axis of the storage tank 14. The channel of the injector 3 is connected to the peripheral part of the storage tank 14.

The dropper works as follows.

During operation under steady state after irrigation water supplied from main or distribution pipes in irrigation pipeline through the charge port of the fitting 2 and the cavity 12 in adminpanel cavity 11 pressure drop according to the equation Q=V, where Q is the water flow rate, l/h;- flow cross section, m2; V is the average velocity of flow in m/s

Water from namebrands cavity 11 through the hole in the ring layer 9 and the pores in the membrane 8 enters the deflector 16 and the wall flows into the reserve tank 14 through the calibration hole 15. Water from the reserve tank 14 through the channel of the injector 3 is fed into the soil only by gravitational forces. Because then, the injector 3, the water is evenly distributed in the soil, capturing around irrigated plants of considerable size. As the injector 3 in the form of a pin 4 with the ribs 5 buried in the soil, the evaporation of water is almost absent, and this reduces overall water consumption and improving the quality of application.

When the hydraulic shock extension of water flow in adminpanel cavity 11 does not repay all the energy and for this reason, the flow of water presses on the ring of the upper layer 9 of the membrane 8. The membrane 8 and the ring 9 by the pressure shifted to the side rings of the lower layer 10. Water under pressure through the channels 22 and the annular gap is extruded into the annular cavity 13.

When filling the cavity 13 of the water out of it by constantly open channels 21 first enters podnimavshaya water flows in a calibrated orifice 15, filling cumulative capacity of 14.

When the pressure fluctuation 0.03 MPa in a calibrated hole 15 water flows in a strictly dosed quantities through the capillaries of the diaphragm 8 and through the annular gap between the top slice 17 of the diffuser 16 and the lower layer 10 of the membrane 8.

When the dropper 8 with a large flow of water through the pores of the injector 3, the tabs 18 and 19 are mutually fixed on the housing 1 on one lip and one depression. To reduce the flow of water enough upper part of the housing 1 with the fitting 2 to pull the lower part of the body.

Multilayer membrane 8 provides differentiated water supply to the injector 3, cleanses it from small impurities and provides the required operational reliability.
