The invention relates to agriculture and can be used in land reclamation for irrigating agricultural crops from closed pressure pipelines.

The aim of the invention is to increase the reliability of operation.

The drawing shows a retractable hydrant, a general view.

Retractable hydrant has a telescopic body, including a fixed lower section 1, rigidly mounted on the pipeline, and three movable coaxially mounted sections 2-.

The stationary section 1 is equipped with a ring magnet 5 on the lower inner side.

The movable sections 2-4 are inserted into each other and are also equipped with ring magnets 6-8 on the lower inner side.

J The movable upper section A has a water outlet 9, equipped with a valve 10, to which the rod 11 is rigidly attached to the locking element. The upper part 12 of the locking element of the valve 10 has a pointed shape that allows free hydration through the soil.

The lower part of the closure element 13, valve 10, provides for the overlap in the upper part 4 in the initial position, as well as the uniform distribution of the irrigation flow from under the valve in the working state of the hydrant,

The piston 14 is rigidly attached to the lower part of the rod 11, which overlaps the inlet open 15 of the upper section 4. The piston 14 has the ability to move inside the upper section 4, the latter

for him guides.

The piston 14 has through-holes 16 displaced relative to its central axis for the passage of water into the cavity of section 4, which are located opposite the end of the ring magnet 8, the upper section. The lower part of the piston 14 rests on an annular magnet 8 of section 4. A compression spring 17 is loosely attached to the piston rod, which with its lower part rests on the piston 14, and there is a gap between its upper end and the body of section 4 to ensure the free movement of the rod 11 inside the upper section 4.

In the initial position of the hydrant, the spring 17 is not stressed, under the influence of magnetic forces of the weight of the rod 11 of the kllpan 10 and the piston 14 are blocked by the outlet 9 and the outlet 15 holes. Ring magnets 5–8, when exposed to each other, ensure that sections 1–4 are pushed into the lower position.

When a hydrant enters the cavity due to the free movement of the rod 11, the piston 14 moves upward within the upper section 4, opening the inlet. 15. At the same time, water through the holes 16 enters the cavity of the upper section 4 and the water outlet opening 9 is opened to allow a certain amount of water to pass, which, wetting the soil, ensures that the hydrant reaches the surface of the soil easier.

With an increase in pressure in the cavity of the hydrant to a degree that ensures the separation of the magnetic stops 5-8, its final extension to the soil surface occurs. A further increase in pressure in the hydrant cavity leads to compression of the spring 17 to failure and the opening of the outlet port 9 to the working state.

When the water supply is cut off and the pressure inside the hydrant decreases, the valve 10 under the influence of the spring 17 and when interacting 14 with the magnetic stop 8 lowers and closes the water outlet 9, and when the magnetic stops of the sections 1-4 interact, they return to their original position. one

With an increase in reliability, irrigation water is magnetized, leading to an acceleration and increase in the growth of irrigated agricultural crops, i.e. for higher yields.
