    A riser tube rigid with a piston head is vertically reciprocable in a cylindrical housing to which water under pressure may be admitted from the bottom to raise the tube into an elevated position, in which its tip extends above the ground, or through a lateral port near the top of the housing to lower the tube into a retracted position below ground. The piston head has a peripheral groove which communicates with the bore of the tube and, in the extended position, registers with an upper set of holes in the housing wall which are connected through a stationary external sleeve with a lower set of holes, lying then beneath the piston head, whereby water from a distributing pipe of an irrigation system can enter the riser tube after having elevated same into that position.

       1-, - The invention relates to extendable hydrants for irrigating agricultural crops and can be used in stationary sprinkler systems. A retractable hydrant is known, which includes a cylindrical body, and which has a movable stand with a central longitudinal hole ending with a dense piston, on the side surface of which a circular groove connected with radial holes with a central hole of the stand is provided, and at the upper end the cylindrical case is connected to an additional the network for immersing the hydrant, and at the lower end with the distribution network for sprinkling. The disadvantage of such a hydrant is that the locking mechanism to the pipe ode for irrigation distribution network is designed as a movable sleeve, which seal is difficult CMAA povyshenno water contaminated with mechanical impurities or irrigation is carried out with application of mineral fertilizers. . The aim of the invention is to provide a hydrant for operation on contaminated water with a shut-off mechanism to the supply pipeline of a water distribution network for sprinkling, implemented in the stationary version, without moving control parts and seals. This goal is achieved by the fact that at the upper end of the cylindrical body, below the point where an additional network is connected to it, radial holes are formed at different levels, externally insulated with a stationary annular sleeve that forms an annular chamber connecting said radial holes coaxially with the annular the piston groove, wherein the distance from the upper edge of the annular groove to the upper surface of the piston is greater than
    between the outer edges of the radial holes in the cylindrical body.
    In Fig.1 shows a retractable hydrant with a retracted stand, a section along the axis; in fig „2 - the same, with the counter raised to the surface.
    The extendable hydrant includes a cylindrical case 1 with an opening 2 for connecting an additional network 3 serving for immersion of the rack (. As well as the openings 2 in the housing 1, the radial holes 5 and b are insulated at different levels by forming an annular ring with the housing wall 1 a chamber 8 connecting the holes 5 and which are made coaxial with the ring groove 9 in the piston 10 mounted on the rack. For the hydrant to function properly it is necessary that the distance from the upper edge of the ring groove 9 d The upper surface 11 of the piston 10 would be greater than the distance between the outer edges of the openings 5 and 6. ..
    The piston 1.0 has radial holes 12, and in the rack 4 there is a through longitudinal hole 13, terminated by a nozzle for sprinkling. The hydrant is connected to the distribution network 1 for sprinkling through the pipeline 15.
    The hydrant works as follows. som, v
    When water is supplied to the distribution network 14, its pressure through pipe 15 is transmitted to the piston 10, which begins to move upward along with the pillar 4. At the same time, the water in the piston space is pushed through the opening 2 into the additional network 3 which moment is connected to the atmosphere “When the piston 10 reaches the upper stop, the axis of the holes 5 co-falls with the axis of the ring groove 9 and the water passes through the hole b, the annular chamber 8, the hole 5, the ring groove 9 and the radial holes 12 to the hole 13 of the rack 4 and beginning sprinkling process
    After sprinkling is completed, the distribution network 14 is connected to the atmosphere, and water is supplied to the additional network 3, the hole 2 enters the piston space, pushes the piston 10, which, together with the stand, begins to move
    down o There is a dive rack. Since Hole 5 opens with the top surface 11 of the piston 10 After the annular groove 9 has dispersed with the holes 6, water does not flow through the opening of the TOR of the rack 4. Water is pushed out of the piston space through the pipeline 15 into the distribution network 14, the plunging of the rack stops when piston 10 reaches bottom stop
    The advantage of the invention is that the retractable hydrant can be used for water with mechanical impurities or when sprinkling is accompanied by mineral fertilizers, the locking mechanism to the distribution network for sprinkling being implemented in a stationary version without moving parts and seals.

    Invention Formula
    A retractable hydrant, comprising a cylindrical body in which a movable stand with a central bore is installed, terminating with a dense piston, on the side surface of which an annular groove is made, communicated by radial openings with the central aperture of the stand, and the cylindrical body is connected to an additional a net for immersing the stand, and at the lower end with a distribution net for sprinkling, characterized in that, in the upper end of the cylindrical body, below the connection point e, to it, an additional network is made at different levels of radial holes, insulated from the outside with a fixed ring sleeve, forming with the housing wall an annular chamber connecting said radial holes coaxially with the piston ring groove.
    2о The extendable hydrant according to claim 1, which is distinguished by the fact that the distance from the upper edge of the piston ring groove to the upper surface of the piston is greater than the distance between the outer edges of the radial holes in the cylindrical body.
    The invention was recognized on the basis of the results of expert examination carried out by the department for the invention of the People’s Republic of Bulgaria.
