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

Known dropper comprising a housing with off, in which, with the goal of self-cleaning drip and simplify its design, the casing 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 authorship 704540, M CL2A 01 G 25/02. Dropper /Year I. Carpi (USSR). - 2630295/30-15; claimed 19.06.1978; publ. 25.12.1979, bull. 47 // Opening. Of the invention. - 1979. 47).

Described dropper for normal operation requires strict vertical orientation of the axis of symmetry of the float shut-off elements. Any slight misalignment leads to poor quality irrigation and negates the clearance holes in the inlet and outlet pipes.

Known dropper containing a body of conical shape with the inlet and outlet nozzles and a fixed float, in which, to improve the reliability and efficiency, it is provided with a mesh filter, which is installed in the lower part of the housing, the float is made in the form of a sphere with slots-conduits, arranged on its surface in mutually perpendicular planes (SU, the author is 88; publ. 07.01.1991, bull. 1 //Open. Of the invention. - 1991. - 1). This dropper is accepted by us as naiblizhajshee equivalent.

The disadvantages of this dropper include breaks the supply of irrigation water, regardless of the degree of its purification. This is because the float is in the form of a ball overlaps the hole of the outlet pipe, because the slot-conduits relate to the casing wall, and the hole tightly blocked by the surface of the ball (it is enough float 10 to rotate around a horizontal axis at an angle of 45o, see Fig.2). This is caused by the low reliability of the dropper.

The invention consists in the following.

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

The technical result - improving the reliability and simplifying the design.

This technical result is achieved by the fact that in the known drip, comprising a housing with inlet and outlet nozzles and set it to float in the shape of a ball, according to the invention, it is provided with an additional float in the form of a hollow sphere, the primary and secondary floats are placed in the cavity of the housing, the surface of which is made in the form of compressed triaxial allipuram, while the body cavity is additionally hydraulically connected to the inlet and outlet nozzles through bypass channels and locking cavities oriented in the direction of the main float in the shape of a ball, placed in the hole of the torus; the body is made detachable, and the plane of the pair of housing parts are oriented to the long axis of the cavity at an angle of 30-60o.

The invention is illustrated in the drawing, which shows a diametrical section of the dropper (primary and secondary floats are placed in the housing cavity in average position).

Information confirming the possibility of implementing the claimed invention are as follows.

The dropper includes a housing 1 with an inlet and outlet nozzles 2, 3 and installed the float 4 in the form of a sphere. The dropper provided with an additional float 5 in the form of a hollow sphere. The material of the float 5 - technical rubber with the given parameters. The main float 4 and the additional float 5 is placed in the cavity 6 of the housing 1. The surface of the cavity 6 is made in the form of compressed triaxial ellipsoid of rotation (damn). The long axis I-I of the ellipsoid of rotation aligned with the geometric axes of the openings of the inlet and outlet pipes 2 and 3. The cavity 6 of the housing 1 the l and 8 and the locking cavities 9 and 10. Locking cavity 9 and 10 in the cavity 6 of the housing 1 is made in the mirror on the axis II-II and oriented concave surfaces toward the float 4 in the form of a sphere. The float 4 is placed in the hole for more float 5 in the form of a hollow sphere. All items droppers have perfect forms and manufacturability of the available Arsenal of plastics. This contributes to the fact that the housing 1 is made detachable. The plane interface III-III of the casing 1 is oriented to the long axis I-I of the cavity 6 (inner surface) at an angle of 30-60o. Lock connection 11 prevents leakage of water from the housing 1.

The dropper works as follows.

Let's consider a dropper under the following provisions: axis I-I posted in the horizontal plane; the axis II-II is oriented in the horizontal plane; the plane of the connector III-III placed in the vertical plane.

Example 1. The symmetry axes of the openings of the inlet and outlet pipes 2 and 3 are oriented in the horizontal plane. With the dramatic opening of the valve in the supply line water under high pressure and at high speed enters the hole in the input pipe 2. Under the pressure of the jet on the path of least resistance on the tube 3. The second stream of water from the inlet pipe 2 on Obvodny channel 7 enters the shut-off cavity 9. Both water flow to fill the cavity 6 of the housing 1. When filling the cavity 6 water hollow floats 4 and 5 emerge above the shut-off cavity 9. The float 4 in the form of a sphere its upper part is approaching the concave surface of the locking cavity 10 and overlaps the opening of the bypass channel 8. The float 5 is also coming to the concave surface of the cavity 6 in the direction of the shut-off cavity 10, opening a hole in the outlet port 3. After the water from the cavity 6 of the housing 1, the main float 4 with water in case 1 goes down and reduces the living section locking cavity 9 and increases the flow area of the bypass channel 8. Moving more of the float 5 and the main float 4 in the cavity 6 of the housing 1 is differentiated from pressure values direct the flow of irrigation water in the outlet pipe 3, providing a preset flow rate (1.5-2.0 l/h), regardless of the pressure drop in water conveyance pipeline.

Example 2. When installing the housing 1 dropper axis I-I straight up additional float 5 in the form of a hollow torus lower part overlaps the opening in the outlet port 2. The main float is 4, she shut planes 9 and 10. Both bypass channel 7 and 8 are open. When the supply of irrigation water under the working pressure of the jet at the exit hits on additional float 5 and even with great effort it presses to the outlet fitting 3. Part of the water inlet pipe 2 enters on Obvodny channel 7 into the closed chamber 9 and flows freely into the cavity 6, filling it. With the increase in water level due to the lifting force of the float 4 in the shape of a ball POPs up to lock the upper sections of the locking cavities 9 and 10. Water from the cavity 6 is freely flowing through the channel 8 to output the outlet fitting 3, and via a supply tube falls either on the surface or by means of the injector in the root layer of soil. With the increase of water level in the cavity 6 of the hollow float 5 in the form of a torus emerges above the outlet pipe 3, and simultaneously closes the opening in the receiving socket 2. Thus the movement of the floats 4 and 5 regulate and evenly serves irrigation water from the cavity 6 in the outlet 3 regardless of the pressure in the communication network system of drip irrigation.

Example 3. Let's consider a drip in an inclined, in the most unfavorable position, i.e. when the vertical position of plosko which overlaps the outlet fitting 3. The main float 4 entirely by the force of its own weight is placed on the surface of the shut-off cavity 9. When water in the cavity 6 of the body energy of the compressed water is extinguished on the surface of the float 5. The water in the space between the housing 1 and the float 5 flows into the lower part of the cavity 6 and merges into a strictly dosed quantities, and then fed into the output nozzle. If you increase the amount of water in the cavity 6, the float 4 in the form of a sphere, surfacing, releases the locking chamber 9. In this case, the water flow increases, because it comes and Obvodny channel 7. Increased volume of water from the housing 1 when filling the cavity 10 is discharged into the bypass channel 8 and is conveyed to the outlet fitting.

Examples of irrigation water from the dropper 3 indicate its stable operation regardless of the position in space.
