One invention relates to impulse injection systems, including in mountainous conditions, impulse sprinkler systems of self-oscillatory action are known, the opening of aatvs automatically increases the pressure in the pneumatic accumulator to a predetermined limit l i Disadvantage of this accessory device It is impossible to ensure their SYN7PHONE operation on the pelvis systems as the force of the self-oscillating valve body depends on the diameter of the working valve and the design pressures therefore with an increase in ms. The dimensions of the locking organ dramatically increase. Exhaustively also a pulsed heating apparatus. A fitted pipe and a irrigation pipeline and consisting of | 3 | a cordless pneumatic accumulator, up to) A nozzle with a turning mechanism and a piston locking organ of a self-oscillatory type S3, .. The geodesic pressure of water is also added to the working pressure, and in the lower polypropylene pipes, the HHorjoia exceeds by several times the allowable value for pulse sprinklers. Therefore, in the mountains, not every irrigation pipeline, the installation of pressure regulators, the borehole apparatus on the Sch1On1x unit are filled earlier, on the upper, their pressure regulators are closed, the burner of the command reduction signal is closed. At the same time, any failure of the pressure limiter regulator results in a full exit from the system of all devices connected to this line. This is the main cause of the slow implantation of pulsed-rain in mountain regions. The purpose of the invention is to increase reliability in operation and to simplify the design. The goal is achieved by connecting the air-accumulator and the irrigation pipe with successively installed reverse valves. a valve and a hydraulically controlled valve connected hydraulically to the output patch of the impulse apparatus, and the valve body is equipped with a spring and valve, and is connected to the atmosphere on the spring side. The drawing is a diagram of the pulse sprinkler pulse to schevalny apparatus consists of gvdropnemloakkumup torus I, «Jvyxodnym pipe 2, sprinkler Vasadki 3 with rotation mechanism zaporftfioroi 4 self-oscillating type, consisting of a working piston 5 and rigidly soedineinogo with it a differential valve 6 Differential valve consists of a discharge tube 7, w | 8 and springs 9, piston 5 is preloaded by spring 10 and between its cylindrical strut (there is a gap with the walls of the casing of the shut-off organ, the area of which is less than the cross-sectional area of the passable tube 7. The diameter of the waste tube 7, size 8, and also the force The springs 9 are selected depending on the upper and lower pressure limits in the pulsed aero winding device,: With the irrigation network, the hydraulic accumulator I is connected by connecting the It valve and the hydroproofing valve 12 in series. The hydro-controlled valve 12 consists of and From the housing, the valve 13 with the stem 14, the springs 15 and 16. The supercontinuous cavity connects the output pipe 2 via the hydraulic communication channel 17. In the initial position, the hydraulically controlled valve 12 is open, the working piston 5 and the plunger 8 are respectively preloaded by springs 10 and 9 to The ends of P1 pipe 2 and pipe 7, the Pulse Sprinkler, operate as follows: When water is supplied from the network, it passes through the hydraulic valve (equalizer valve 12 and return valve 11 enters the hydraulic accumulator I) and fills it up to the upper working pressure. Through the gaps of water; comes under the piston 5, tightly pressing it to the end of the outlet nozzle 2. When the water pressure in the hydro - Ш1вш оаккум} shtora reaches the upper limit of the plunger: 8, compressing the spring 9, drastically drops down, water1 from under the porig 5 through the sfrskuk) the pipe 7 is discharged into the outlet 2, the pressure under the piston decreases and under the action of pressure in the piston piston 5 drops sharply down and a shot occurs. The pressure in the outlet pipe 2 through the channel 17 is transmitted to the membrane 16 and the valve 13 closes the water supply from the network. With a decrease in pressure in the accumulator to the lower limit, the plunger 8 under the action of the spring 9 closes the waste tube 7, the pressure in

pnevmoakkumul grief and under the piston 5 is equalized and under the action of the spring 10 the piston 5 is realized and closes the exit,

 After the shot, when the pressure above the meme K1VOY abruptly decreases, the flap t3, under the action of water pressure in the network, remains in aaKpbiTOM position, since ratomajD6 is its transverse c & vm more apothecs pgtok "

The control signal for reducing the pressure of the head and head pulses valve t3 opens, of course, with the pulse ntffyzhina 15. OfatyaYkhlaaan tt (U) gagatstvuet sphosu. water in and out of the water. The sprinkler is ready for the next wind ditch.

Thus, the aapor organ of the impulse | SNOW sprinkler: resets the pressure itself, the IKS of allowing its increase is higher than the calculation. 7 - g -

Whom does the hydrowanned control unit control the arrival of the head unit in the accumulator, play command of the head pulse generator and ensure the synchronous operation of all devices in the systole. In the event of a failure of a hydraulically controlled clathis and a pulp sprinkler, Ashkharat will independently fire shots, preventing overfilling of the hydro-pneumatic accumulator. If the valve 12 "is disconnected, then the device stops operation | and the failure of the valve does not lead to the removal of the apparatus, but only the weight of Kbia o disrupts the irrigation process - there will be a slight over-wetting or under-wetting of the section.

The use of the proposed devices for mining in mining conditions makes it possible to increase the reliability of the system and its efficiency in a readable manner.
