Description

The invention relates to pumping and can be used in systems for the automatic delivery of liquids, especially to irrigated areas of mountain slopes.

The purpose of the invention is to increase productivity by reducing the duration of injection cycles.

Figure 1 is a diagram of the device issuing liquid to the consumer; in fig. 2 - the same, with an additional float; .on FIG. 3 - a clamp with a bar, a section.

The device for dispensing a liquid to the consumer contains a working chamber 1 with suction and discharge nozzles 2 and 3 with check valves 4 and 5 placed in the chamber 1 a hollow float 6 with an inlet 7 and a piston 8 connected to the float 6 by means of a rod 9, and a capacity 10, reported from the cavity of the float 6 che30

a cut inlet 7, device 5 received from level sensor 13, the source 11 also includes a compressed gas source 11 with a gas distributor 12 and a gas distributor control system including level sensors 13; installed in the working chamber 1, and the remote control 14, communicating with the sensors 13, while the float 6 is made tightly and equipped with a gas supply nozzle 15 connected to the gas distributor 12, which is equipped with a rotary lever 16, and the remote control 14 with electromagnets 17 and 18, the rotary lever 16 is installed between the electromagnets 17 and 18. The container 10 is equipped with an additional float 19 with a rod 20 and two limiters 21 and 22, the lever being placed between the limiters 21 and 22, and one of the electromagnets is provided with a lock 23. Float 6 s packed with a reflective screen 24 placed between the inlet 7 and the gas supply nozzle 15.

The device works as follows.

Upon receipt of the liquid from the working chamber 1 through the discharge pipe 3 to the consumer air from the float 6 through the pipe 15 and the gas distributor 12 will be released into the atmosphere, because the rotary lever 16 interrupts the connection of the gas distributor with the source 11 of compressed gas and opens to the atmosphere In this moment

energize the electromagnet 18, which interacts with the lever 16, i.e. turns it, and from the source 11 the compressed gas flows through the pipe 15 into the float 6, which floats, and the liquid is displaced from it through the inlet 7 into the container 10, When the float 6 floats, at the same time the piston 8 rises through the rod 9, and work is done to displace the fluid. The pumping stroke is over.

During the cycle of displacing water from the float 6, the stream escaping from the nozzle 15 splits against the screen 24, which prevents the direct influence of gas energy on the surface of the liquid, which contributes to the speed of the liquid flowing into the container 10. Conversely, when water flows through the hole 7 under a large pressure drop from the container 10 flow, breaking on the screen 24, allows the use of a uniform increase in gas pressure in the float 6. An additional float 19 with the rod 20 can be used as a switch. 19 simultaneously with the control panel 14, the voltage is applied to the electromagnet 17 or 18, the latch 23 secures the rod 20 for a predetermined cycle of the gas distributor 12, corresponding to the 1ZII interaction of the rotary lever 300196

the suction inlet 2 is closed by a check valve 4 under the action of the hydrostatic pressure of the fluid in

In this case, the free end of the pivoting lever 16 is fixed by an electromagnet 17. At the same time, liquid 10 enters the tank 10 through the inlet 7 into the float 6, and the water is expelled. no air remains through the gas distributor 12. into the atmosphere. As soon as the water reaches a certain (predetermined) filling of the float 6, the latter starts to descend under its own weight downwards and through the rod 9 acts on the piston 8, which also goes down, valve 5 closes the pressure pipe 3, and valve 4 opens and the water rushes into the working chamber I through the pipe 2 to the specified level 13 sensors. At this time, the fluid suction stroke is over.

At the command of the remote control 14.

Upon reaching full flow of fluid from the tank 10 into the float 6, the voltage is applied to the electromagnet 17, and the rod 20 with the float 19 under its own weight sinks to the bottom of the tank 10, Limiter 22, interacting with the lever 16, rotates it to the appropriate distance. The distance between the limiters 21 and 22 can vary as the flow rate in chamber 1 changes, and the operation of all elements of the clamp 23 is repeated in the sequence described.
