(57) Abstract:Usage: in agriculture. The inventive sprinkler nozzle bore a hole in the lower part of the body is tapered. The nozzle is supplied is placed in the hole of the bottom part of the spring loaded cone element with an axial hole for the passage of a preset flow rate when the maximum pressure, the thrust flange with holes around the perimeter and fixed coaxial tapered bore hole stabilizing pipe. The living section of the pipe at the outlet is selected equal to the cross-section of the conical bore hole at the exit to pass a given flow rate at the specified minimum pressure. The deflector is made in the form of a flat reflector located with the possibility of removal at the cone base, the diameter of which corresponds to the diameter of the working surface of the reflector. 2 Il. The invention relates to designs of nozzles for spraying a liquid and can be used mainly in agriculture.Known kratkotrajna nozzle, which is used in dual console sprinkler unit DDA 100 MA, including a housing, a diaphragm with a hole and the bar is eskow seedling cultures and seedlings of agricultural plants under the direction of the deflector for the top up and the loss of water through evaporation and entrainment by the wind in the direction of the deflector for the top down.Closest to the invention to the technical essence and the achieved result is a sprinkler nozzle comprising upper and lower housing with connecting thread and the through holes, the legs and the deflector 
A significant drawback of this nozzle is that it requires some effort to configure it on a given mode of operation taking into account the specific conditions and, importantly, does not take into account fluctuations of pressure during operation. Fluctuations of pressure, which are inevitable in practice, lead to a change in the flow rate, the size of drops, spray radius and so on, and thus the violation of the quality of the nozzle as a whole. Therefore, the design of the nozzle should allow automatic control of the flow pressure drop in the process.The objective of the invention is to provide a specified flow rate and unstressed nozzle when the pressure within the established limits.The problem is solved in that the sprinkler nozzle, comprising upper and lower housing with connecting thread and the through holes, the legs and the deflector according to the invention the penetration hole in the bottom of vypolneniem to skip a specified flow rate when the maximum pressure, thrust flange with holes around the perimeter and fixed coaxial tapered bore hole stabilizing coupling, the living section which output is selected equal to the cross-section of the conical bore hole at the exit to pass a given flow rate at the specified minimum pressure, while the deflector is made in the form of a flat reflector located with the possibility of removal at the cone base, the diameter of which corresponds to the diameter of the working surface of the reflector.In Fig. 1 shows a schematic diagram of the sprinkler nozzle of Fig. 2 section a-a of Fig. 1.Sprinkler nozzle includes connecting part 1. the upper and lower parts 2 and 3 of the housing and the through holes 4 and 5, the legs 6 and the deflector 7.The penetration hole 4 in the bottom part is made conical, and the nozzle is equipped posted in last spring loaded by a spring 8 and a limit element 9 with an axial opening 10 for the passage of a preset flow rate when the maximum pressure, the thrust flange 11 with a hole 12 on the perimeter and fixed coaxial tapered bore hole 4 a stabilizing pipe 13, the living section on which the output is set equal to the m minimum pressure, stabilizing the pipe 13 has a cone 14 and 15 of the cylindrical part.The deflector 7 is made in the form of a flat reflector located with the possibility of removing the cone on the base 16, the diameter of which corresponds to the diameter of the working surface of the reflector.Diameter of through hole 4 more axial holes 10. In the initial position under the action of the spring 8 tapered element 9 is shown in Fig. 1 position in which its top is located at the level of the holes on the bottom part 3 of the housing, resulting in additionally formed between the casing and the walls of the tapered hole 5 a conical annular gap 17, and between the outlet and a flat reflector optimal distance H.Sprinkler nozzle operates as follows.During operation, water from the connecting portion 1 passes through the passing hole 4 of the upper 2 part of the body of the nozzle in the axial hole 10 of the conical element 9, then in stabilizing the pipe 13. At the same time the water fills the space above the conical element 9 to a height "h" (as the diameter of through hole 4 of the upper and lower parts 2 and 3 buildings more axial hole 10 of the conical element 9) is t also in stabilizing the pipe 13. In its conical part 14 is the connection threads of the axial bore 10 and the annular gap 17, and then in the cylindrical part 15 stabilization of the jet that comes out of the nozzle 13 is already concentrated. This is facilitated in addition to the smooth transition of the conical part 14 in the cylindrical 15 and the fact that the living section of the roll pipe 13 part 15 provides a specified flow rate at the specified minimum pressure. From the inlet stream enters removable flat reflector 6, the diameter of the working surface of which corresponds to the diameter of the base of the conical baffle that comes with it in the form of a film in a horizontal plane and upon further movement in the air dissolves in rain drops that fall under its own weight on the irrigated surface. Depending on specific conditions: wind or high enough temperature, you can only use the cone base as a vent.In this case, the drops will be directed or down at a certain angle (reduced demolition) or up (hydrated surface layer of air and its temperature drops).With increasing pressure in the system to set the maximum cone element 9, overcome Kriva holes 12 in the flange around the perimeter. The result works only axial hole 10, which is designed to pass a given flow rate when the maximum pressure, and held for the optimal distance between the reflector and the output hole "H".Thus, rainwater showerhead enables relatively simple and reliable automatic settings for a given flow rate and unstressed nozzle when the pressure within prescribed limits during operation, which is important for producers and distinguishes it from known structures. Sprinkler nozzle, comprising upper and lower housing with connecting thread and the through holes, the legs and the deflector, wherein the penetration hole in the lower part is made conical, and the nozzle is equipped posted in last spring cone element with an axial hole for the passage of a preset flow rate when the maximum pressure, the thrust flange with holes around the perimeter and fixed coaxial tapered bore hole, the stabilizing tube, the living section which output is selected equal to the cross-section of the conical bore holes on the output of the reflector, located with the possibility of removal at the cone base, the diameter of which corresponds to the diameter of the working surface of the reflector.
