    Apparatus for impulse spraying. A float valve is disposed at the lowest end of a liquid/gas accumulator which is connected via a connecting pipe having the float valve interposed therein to a hollow member having a vertically divided space to the upper end of which an outflow pipe leading to a sprinkler is connected. A water distribution pipe leading from a water supplying conduit is attached to the lower end of the divided space. A selectively operated shut-off valve in the hollow member is interposed between the outflow pipe and the connecting pipe, the shut-off valve functioning to shut off the outflow pipe when the water pressure in the upper end of the divided space in the hollow member is lower than that in the lower end of such divided space, and to open the outflow pipe when the pressure in the upper end of the divided space exceeds the pressure in the lower end of the divided space.

    The invention relates to hydropneumatic batteries for pulsed irrigation used in agriculture for irrigating agricultural crops. A device for pulsed sprinkling is known, consisting of a water tank with a float check valve, an inlet pipe connected to a distribution pipe, an outlet pipe connected to a rain device, a connecting pipe between the water tank and an intermediate chamber with a shut-off organ (USSR Author's Certificate No. 882482 , 1sl. And 01 G 25/00 1978) The drawbacks of the device are the outflow of water from the water-air tank through the control valve back to the distribution pipeline at the initial moment of the low-pressure signal, which reduces the reliability of the valve and causes the distribution pipe having a diameter larger than the minimum possible to be used; as well as the possibility of air penetration from the distribution network into the water-air tank, thus disturbing the value of the previously created excess air pressure in it. The object of the invention is to create a hydropneumoaccumulator dp of pulsed sprinkling, in which the possibility of water flowing out of the water-air tank back into the distribution pipeline when signals of reduced pressure are eliminated, and ensuring maximum reliability of control pulses and decreasing pressure in the supply water

    the piping system with the minimum diameter of the distribution piping, and the possibility of air entering the air reservoir (air that moves with the water through the piping of the system) would also be eliminated.
    The task is solved by means of a hydro-pneumatic accumulator for pulsed sprinkling, in which the shut-off element is made in the form of a membrane, and the connecting pipe is connected to the distribution pipe through an inlet pipe having a horizontal section equipped with a reverse valve, while the water-air tank is tilted and the float valve is placed at the lowest point of it.
    The end of the output pipeline is normally closed by the membrane of the intermediate chamber, the connecting pipeline is mounted with a slope, with its end on the side of the intermediate chamber located above its end on the side of the air-flow reservoir float valve.
    In another version of the hydropneumoaccumulator, the connecting pipe is mounted along the axis of the water-air tank and is isolated from it, and at its upper end it ends with a chamber. Inside, along the axis of the latter, a cylinder is fixedly fixed, communicating through an inlet orifice in the lower base with a passage of 1m through the chamber walls, perpendicular to its axis, with a water distribution pipe. The upper base of the cypinder is terminated with a guide cone, which is coaxial with the outlet pipe a floating float with an o-ring seal and an axis, on the lower end of which there is a blind axial bore with two lateral slots in which the pin is fixedly fixed, connecting with the piston axis. The diameter of the piston is larger than the diameter of the inlet of the cylinder, which has holes in the walls, which communicate the water distribution pipe with the chamber cavity. The outer diameter of the cylinder is smaller than the inner diameter of the chamber, and the diameter of the float is smaller than the diameter of the piston. Vertical piston stroke a little more vertical474
    of the float plus the vertical stroke of the pin in the side slots of the float axis.
    The advantages of hydro-pneumatic accumulator dp pulsed sprinkling are as follows: water is not allowed to flow out of the water-air reservoir back into the water distribution pipeline when signals of reduced
    pressure, which ensures maximum reliability when triggering increasing and decreasing control pulses with the minimum diameter of the water distribution pipe; Air can not get into the air tank together with the water entering through the distribution pipes of the sprinkling system.
    Figure 1 shows a hydropneumoaccumulator for pulsed sprinkling, a general view, with a signal of increased pressure of water in the water distribution pipe; in Fig.2 the camera, the section along the axis, with a signal about the reduced pressure of water in the water distribution pipe; on fig.Z - hydro-pneumatic accumulator, (option) section along the axis.
    I
    The hydro-pneumatic accumulator for pulse irrigation consists of a water-air tank 1, in which there is a float valve 2 located vertically in the lowermost part of the tank 1. The tank 1 is connected to the supermembrane space 4 of the intermediate chamber through a connecting pipe 3. five.
    Vertically along the axis of the latter, the output pipe 6 is mounted, leading to the sprinkler 7. And the submembrane space 8 by means of pipeline deviation
    9 is connected to the water distribution pipe 10. The water distribution pipe 10 is connected to the connecting pipe 3 via the inlet pipe 11c.
    a check valve 12 in the place between the float valve 2 and the chamber 5. The lower end of the outlet pipe 6, which is located in the supramembrane space of the membrane chamber 5, is normally closed by the diaphragm member 13. The water distribution pipe 10 is located above the connecting pipe 3, and the inlet pipe 11 connecting the water distribution pipe 1 to the connecting pipe 3 has a vertical 14 and a horizontal 15 sections, and on the horizon. Talc section 15 is equipped with a valve 12. The connecting pipe wire 3 is mounted at an angle, and its end on the camera side is located at its end on the side of the float valve 2 of the water supply reservoir 1. In the example of the hydropneumatic accumulator for impulse sprinkling, it is shown that the bottom of the air reservoir 16 and parallel to its axis is located the guiding chamber 17 of the float gate 18, the opening under which is connected by means of smoothly bent bend 19 with the vertical position But the axes of the tank 16 and are isolated from the latter by the connecting pipe 20, terminating above the tank 16 by the chamber 21. The chamber 21 is connected at its upper end to the outlet pipe 22, and inside it, along its axis, is fixedly mounted a cylinder 23 connected to its lower end by the inlet from the 24, with the water distribution pipe 25 perpendicular to its axis passing through the walls of the chamber 21. The cylinder 23 ends with a guide cone 26 at its upper end, coaxially with respect to the output pipe 22 The results of which are mounted floating float 21 with. an annular seal 28. At the lower end of the axis 29 of the float 27 there is a blind axial bore 30 with two lateral slots 31 through which the float 27 is connected by a floating fixed pin 32 with the axle 33 of the piston 34 placed in the blind axial bore 30. The diameter of the piston 34 is larger than the diameter the inlet 24, at a certain distance above which, in the walls of the cylinder 23 are drilled holes 35 and 36 connecting the distribution pipe 25 with the cavity of the chamber 21. The external diameter of the cylinder 23 is less than the internal diameter measures 21 and the diameter of the float 27 is larger than the diameter of the output pipe 22 and smaller than the diameter of the piston 34. The vertical stroke 0476 of the piston 34 is slightly larger than the vertical stroke of the float 27 plus the vertical stroke of the pin 32 in the lateral slots x 31 of the axis 29 of the float 27. The hydraulic reservoir operates as follows. Pre-pressurized tank 1, which is made in the form of a pipe and mounted at a small angle relative to the horizontal plane, is pressurized to equal the lower permissible pressure limit for normal operation of the sprinkler 7. At an overpressure signal, water from the distribution pipe 10 the deviation of 9 into the submembrane space 8, and through the inlet pipe I1, the check valve 12 and the connecting pipe 3 - into the above-membrane space 4 and one temporarily with this into the air reservoir 1. Since the pressure force acting on the membrane 13 in the submembrane space 8 is greater than the force acting on the membrane 13 in the supramembrane space 4, the membrane 13 closes the outlet pipe 6 and the water does not flow to the sprinkler 7. At a signal of reduced water pressure in the water distribution pipe 10, the check valve 12 closes the inlet pipe 11J and the membrane 13 opens the outlet pipe 6. This begins the process of sprinkling with water accumulated in the tank 1 th is stopped after the decline of water level in the tank 1 to the float valve 2. Work gidropnevmoakkumul torus taken along predpozhennomu embodiment. Beforehand, insignificant quantities are poured into the air reservoir 16 through fitting 37 and faucet 38 and air is injected to a certain pressure that corresponds to the lower permissible pressure limit for normal operation of the sprinkler 7 connected to the outlet pipe 22. When the pressure in the distribution pipe 25 is signaled, water from it through the inlet 24 enters the cylinder 23. The piston 34 is lifted upwards, and by means of the pin 32 it raises the pop 27 K closes the exit Pipe 22, at the same time, water through holes 35 in the walls of cylinder 23 enters chamber 21. Pipe 20 and elbow 19. When the pressure in pipe 20 is equal to and begins to exceed the pressure of pre-forced air, float valve 18 rises and water through The slot 39 of the guide chamber 17 enters the water-air tank 16, where it begins to accumulate due to air compressing in the upper part of the tank 16. After equalizing the pressure in the water distribution pipe 25 with the pressure in the tank 16, the process of water accumulation stops and under the action of its own weight the piston 34 is lowered down until the pin 32 stops against the lower end of the side slots 31. With this movement, the piston 34 covers the holes 35. After the signal about the reduced pressure in the pipeline 25, due to the created difference between the pressure in the piston and the piston and the piston spaces of the cylinder 23, the piston 34 is lowered down and through the pin 32 pulls the float to 27, opening the outlet pipe 22. The water accumulated in the water-air tank under the action of the expanding air is pushed out impulsively to the outlet pipe 22. When the water level approaches the bottom of the tank 16, the float valve 18 is lowered down into the guide chamber 17 and hermetically covers the outflow from the tank 16 hole. This completes one cycle of the operation of the hydropneumoaccula tooo. If air enters the distribution pipe 25 along with the water, it is separated in the upper part of chamber 21 and, after a low pressure signal, is released into the atmosphere through the sprinkler 7. and this way it is prevented from entering the tank 16.
