    The invention relates to agriculture and can be used in closed irrigation systems with control based on pressure change signals in the system.
    A valve is known for controlling a sprinkler system (see auth. St. USSR no. 1212381, cl. L 01 G 25/16, 1981) which includes a casing installed on the discharge and distribution pipelines with a stop valve.
    The disadvantage of this valve is design complexity.
    Also known is a valve for a sprinkler system (see ed. St. DPR No. 36054, cl. A 01 G 25/00 1980), which includes a housing mounted on the pressure and distribution pipelines with equal diameter seats, a stop valve with a vertical mounted hydraulic cylinder, under the piston cavity of which communicated with the control pipeline.
    The disadvantage of this valve is the low reliability of operation with long-term control signals.
    The purpose of the invention is to increase the reliability of operation with long-lasting pressure change signals.
    The goal is achieved by the fact that the body is located vertically and is made in the form of a tee installed in the line of the discharge pipeline by means of a knee and an intermediate pipe, the seats are fixed inside the tee, and the locking member is located between them with the possibility of vertical movement and contact

    With a piston rod, the hydraulic cylinder of which is attached to the tee under the valve, and its supra-cavity cavity is in communication with the aperture of one of the seats and with the distribution pipeline, the valve in the form of an end valve with. a central hole and vertical legs with internal projections and a plunger with a central cone and two annular grooves, with an end bolt mounted over the plunger to form an intermediate cavity, the internal projections are placed with the possibility of movement in the first annular groove of the plunger, the cavity of the second groove of which is communicated by longitudinal axial holes with an intermediate cavity, the diameter of the central hole of the end gate is smaller than the diameter of the base of the central cone plunger a, and the outer diameters of the face gate and the second annular undercut are equal to each other and larger than the diameter of the bore holes of the seats, the distance from the saddle to the edges of the tee intermediate pipe is equal to the total height of the face gate and plunger, the stroke of the piston rod is greater than the stroke value of the plunger relative to the end gate.
    The drawing shows a valve for controlling the sprinkler system, a slit.
    The valve for controlling the sprinkler system consists of a body made in the form of a vertically facing tee 1, a locking member 6 made in the form of an end bolt 4 and a plunger 5 located between the gables and 3 with the possibility of vertical movement between them. Saddles 2 and 3 are fixed inside groynik-h 1 and have holes 27 and 28 of equal diameter. The end gate 4 has a central hole 7 and vertical legs 8 with internal projections 9. The plunger 5 is made with a central cone 12 and two annular recesses 10 and 14. The front gate 4 is installed above the plunger 5 to form an intermediate cavity 11, the internal projections 9 are placed with the possibility The displacement in the co-axial recess 10 of the plunger 5. The cavity of the annular recess 14 is communicated through longitudinal axial holes 15 with the intermediate cavity 11. The tee 1 is installed in the line of the discharge pipe

    With the cone 12, the holes 7 and the end gate 4, the holes 27 of the sedp 2. When the next signal decreases the water pressure in the control pipe 26 and the pressure in the pressure pipe 18 increases, the piston rod 22 under the action of the pressure of water in the over piston cavity 19 of the hydraulic cylinder 23 lowers to the lower position . The end gate 4 and plunger 5 remain in the extreme upper position, supported by the pressure of water that flows from the discharge pipe J5 to water 18 through the over piston cavity 19 and the spindle current 20 to the distribution pipeline 21. After the end of the water supply to the distribution pipeline 21 in the pressure pipeline, a pressure lowering signal at which the plunger 5 opens the hole 7 of the face gate 4, lowering down to the inner lugs 9 of the gate 4. The pressure from both

    water 18 by means of knee 17 and 25 sides of the face gate 4 of the intermediary pipe 16. The hydraulic cylinder 23 is fixed on the tee 1 under the plunger 5 of the valve body 6, its over piston cavity 19 is connected to the hole 28 of the saddle 3 and through the pipe 20 with the distribution pipe 21. Podporshneva the cavity 24 through the opening 25 communicates with the control pipeline 26. The plunger 5 is installed in the tee 1 with the possibility of contact with its end
    13 with a piston rod 22; The diameter of the central hole 7
    face bolt 4 is smaller than the diameter of the base of the central cone 12 of the plunger 5. External diameters of the face bolt 4 and the annular recess
    14 are equal to each other and larger than the diameters of the holes 27 and 28 of the saddles 2 and 3. The distance from the saddles 2 and 3 to the edges of the intermediate pipe 16 is equal to the total height of the end gate 4 and the plunger 5. The piston rod has a stroke greater than the stroke of the plunger 5 relative to the end gate 4.
    The valve for controlling the sprinkler system works as follows.
    With a pressure decrease signal in the pressure pipe 18 from the side of the nozzle 16 and an increase in pressure in the control pipe, the piston rod 22 pushes the plunger 5 and with it the end valve 4 to close 5
    It also sinks down along with the plunger 5 until it closes the orifice 28 of the seat 3. With the subsequent signals of pressure increase and decrease in the flow pipe 18, the distribution pipe 21 remains closed and water passes through tee 1, knee 17 to the following valves, turning on and off them consistently. All valves are simultaneously returned to the initial position after the formation of the pressure signal in the control line 26 in combination with the pressure signal
    The pressure in the discharge pipe 1 of the sprinkler system.
