Description

The invention relates to agriculture, in particular, to irrigation technology, and can be used to automate water distribution on the intra-irrigation network.

The purpose of the invention is to increase reliability and efficiency by expanding the operational capabilities of the device.

The drawing shows the proposed device.

The device comprises a tubular water outlet 1, rigidly attached thereto with a collar 2 and locking screws 3 of a membrane drive, divided by a membrane 4 into a working chamber 5 and a driving chamber 6, a pulse tube 7. Working chamber 5 is connected with a tubular water outlet 1, with irrigator 8 and holes 9.

The drive chamber 6 communicates with the tubular outflow 1 of the impulse tube 7 and is equipped with a drain channel 10. The device includes a float actuator 11 connected to a two-way valve 12 via a rod 13 placed inside the drain channel 10. The float actuator 11 is connected by a hinged link 14 with a double-sided valve 12. The double-sided valve 12 is installed with the possibility of blocking the impulse tube 7 or the drain channel 10. The drain channel 10 is threadedly connected to the casing of the drive chamber 6 and fixed by the adjustment nut 15.

The device works as follows.

In the initial period, when there is no water in the fill 8, the valve 12 closes the opening of the pulse tube 7 under the action of the mass of the float actuator. Hydrodynamic forces move the membrane 4 and the flow of water fills the working chamber 5 and through the openings 9 flows into the sprayer 8. But as far as filling the fill B the float actuator 11 pops up and by means of an articulated linkage 14, the valve 12 moves away from the orifice of the impulse pipe 7. At this time, the water through the impulse pipe 7 enters the - drive chamber 6, and

but this results in its outflow from the tubular outlet 1 into the working chamber 5 and through the windows 9 into the irrigator B. The float actuator 11 continues

floating up and through a hinged link 14, the valve 12 approaches the edge of the drain channel 10. When the valve 12 closes the holes in the drain channel 10, the pressure in the drive chamber 6 and the water outlet 1 is equalized. The hydrostatic force arising due to the difference of the areas of the membrane 4 and the outlet 1, presses the elastic membrane 4 against the edge of the outlet 1, closing it tightly. The outflow of water from the outlet 1 stops.

When the water level in the sprinkler 8 is lowered due to the operation of the sprinkler machines, the float actuator 11 is lowered and the valve 12 moves away from the edge of the drain channel 10 by means of an articulated linkage system 14 and the pressure from the drive chamber 6 flows through the drain channel 10. Pressure in the drive chamber 6, the water outlets are lowered and open.

The flow of water passing through the device smoothly changes from the maximum — with the lowest position of the float actuator 11 and the valve 12 closed by the impulse tube 7, to medium with the average position of the float actuator 11 and; valve 12 and until fully closed with the extreme upper position of the float actuator 11 and the drain channel 10 closed by valve 12. Similarly, the process goes from complete closing to maximum opening of the regulator.

Without changing the flow range, the level range decreases when the drain channel 10 is screwed into the KopiTvc drive chamber 6, and when the drain channel 10 is screwed in, the level control range increases.
