Abstract

Various alternative embodiments of a deflector suitable for the nozzle unit of a sprinkler are shown in order to provide a uniform and easily adjustable spray pattern over a wide angular range. In a first possible embodiment of the invention, the deflection surface of the deflector is provided with grooves extending radially towards the separation edge, the flanks of which are rounded at the transition to the surface of the deflection surface. In a second alternative embodiment of the invention, the grooves in the deflection surface of the deflector extending radially towards the separation edge end at a distance A from the separation edge. In the third alternative embodiment of the invention, in the deflector, the transition region between its deflection surface and the stop portion formed thereon is designed with a radius. Although each of the individual embodiments already leads in itself to an optimized spray pattern, the deflector can be further improved by combining two or all of the alternative embodiments, as these alternatives complement one another synergistically without the individual aspects having to be adapted to one another.

Description of the invention: [Technical field to which the invention belongs] The syllabus of the syllabus and the stalking of the bamboo stalks, 11 Rotary spray to adjust the spray area [Prior Art] The sprayer is usually used to automatically wash the park and lawn. This is called the rotary sprinkler 2 enough to wash; the Liqi display area covers up to 36G. The fineness of the limbs is known. Rotary turn usually has a «collar H base, and the nozzle configuration with a secret water connection shutoff includes a nozzle with at least a spray nozzle that directs the flow deflector. This nozzle configuration is usually placed upstream of the liquid outlet. . The liquid ejected from the injection nozzle is diverted by the diverting diverter so that it is ejected to the area immediately adjacent to the water sprinkler, as described in U.S. Patent No. 4,579,285, A. The nozzle unit is typically designed in such a way that the angular extent of the spray zone can be defined in a variable manner. Rotating light hour nozzle units with variable defined spray areas are known, for example, from German new type DE2G2GG7G144G7U1 or German patent DE6GGG3600T2. Some of the deflectors have a deflector diverter mounted on the body and disposed on the surface thereof as a line or an arch. Hybrid surface ±. The guide filament surface is defined by a high or low bend age such that rotation at the junction of $30G causes the differential surface to form a substantially radially extending stop. The surface of the body opposite the deflector turning surface of the flow diverting deflector has a surface adapted to the shape of the diversion steering surface and is also provided with a radially extending stop. The turns _ and the fields can be phased with each other with the help of a rotating machine, so that the stops can be adjusted to the desired angular position relative to each other. The position of the stern portion thereby defines an angular extension of the surrounding area sprayed by the rotary sprinkler and the stop defines a flow of water on the diversion steering surface of the diverting diverter. The liquid distributed by the sprinkler due to the flow of liquid against the stop has a direct spray of a spray pattern in these areas. It can be seen that the direct injection Chenglin sign varies according to the relative positions of the two stop parts, so it is difficult to predict. In order to be able to guide the liquids ejected by the rotary sprayer to the respective angular extents of the sprayed overall angular extent, as suggested in U.S. Patent Nos. 4,739,934 and 4, 2010, 433, , a baffle extending at the stomach edge (four) of the surface of the diverting diverter. Thus (4) the degree of precision to be distributed: even if the jet flows at an angle to the diverting diverter, for example: or t, due to the geometry of the surface of the diverting diverter, the liquid is deflected by the angle - Usually in the case of a spiral table. As an alternative to forming a target-oriented jet guide steering plate structure, the basin is known from the US Patent No. US41_A and No. 259η or by the patent application No. DE19634332A1. The diversion of the gorge is Ο ❹. Both the baffle and the trough structure substantially prevent the liquid flowing on the diverting diverter from having a desired uniform angle independent spray pattern [invention]. SUMMARY OF THE INVENTION The object of the present invention is to provide a flow diverter of a nozzle unit of an inspector that provides a spray pattern that is uniform and uniform at a wide range of different angles. The blue of the present invention is solved by a flow guiding diverter having a nozzle single 7L of the vine sprayer of the patent application. In this case, the patents describe three alternative implementations, each of which has solved the problem separately, but combined to produce the best solution. Advantageous embodiments of the invention and evolutionary extensions of the invention are described in the context of the patent. The flow guide turns to a nozzle unit that is suitable for spraying n, the nozzle unit having a water supply connection, a liquid outlet, and a guide, nozzle arrangement connected by a water supply to the liquid outlet, the nozzle arrangement having at least a Confucian nozzle disposed upstream of the miscellaneous outlet The bedding is placed on the guide. The guide is provided with a linear or arched diversion steering surface with low and high curved mosquitoes toward the side of the spray nozzle, such that rotation at the joint 36 causes the differential surface to form a substantially radial direction. Extended stop. An isolation edge ' is formed on the low bending line of the flow diverter's direction to be substantially perpendicular to the discharge direction of the injection nozzle. In a first possible embodiment of the invention, the diversion steering surface of the flow diverter is arranged to extend radially toward the slot of the isolating edge, which is curved on one side of the surface that transitions to the diverting steering surface. Thereby the liquid distribution is only guided in moderation. The advantage is that, although it is turned to (n) by n 201043340 - angle n or by the steering angle of its position _ guide ship, the offset of the whole angle of the uniform injection of the minimum state of the shirt ring. In a second alternative embodiment of the invention, the slot in the diverting steering surface of the diverting diverter extends radially away from the isolating edge by a distance. Thus, although the guide slots direct the liquid to be diverted, it is directed by the guide to the uniform edge region of the surface before being dispersed into the spray area. The main individual jets that will result are thus again heavily loaded by the ship. Because of the fact that only the self-mixing zone forms a whole-flow-to-surface--small area, the micro-Jewishness of the student is a neglect. In a third alternative embodiment of the invention, the deflector diverter t is designed to have a radius in its transition surface and stop portion. This prevents a direct transition from the diversion steering surface to the stop formed thereon, thereby reducing the force of the flowing liquid acting perpendicularly at the stop. This allows the direct jet caused by the reverse force to be considerably reduced by the spray pattern that flows from the sprinkler. From the point of view of providing an easy-to-adjust and uniform spray pattern, if combined with two or all alternative embodiments according to the invention, the diversion deflector according to the present invention is thus optimally designed in the best way. This means that the real financial styles complement each other and do not need to adjust each other individually. For the side of the groove, it is designed in such a way as to increase its separation distance along the radial direction thereof toward the direction in which the separation edge extends, thereby further reducing the undesired liquid dispersion caused by the guidance and becoming an individual (four) button. Advantage. If the slot extends less than the isolated edge of the diverting diverter, the slot expansion towards the uniform edge surface of the diversion steering region produces a more rounded transition, further improving the expansion of the jet. For grooves and §, it is also visibly designed to reduce its depth along its radial direction toward the direction of the isolation edge. In addition to the expansion of the trough or as an alternative to the expansion of the trough, this embodiment also results in the advantage of each of the different streams, and thus has a uniform jet flow pattern. If the groove is designed such that the depth profile becomes smaller towards the isolated edge of the flow diverter, it is possible in a particularly advantageous manner to divide the depth of the wheel toward the depth of the wheel by at least two different portions of the 201043340 inclination. Distance from the edge - a small tilt. It thus has a shovel, and the portion should exhibit no inclination or a reduction in depth compared to other portions, without the need to be too deep and to create a relatively sharp diversion steering deflector wall thickness from the edge. The end of the groove away from the edge 'this can result in a larger profile with a sharp turn to the surface of the secret portion of the liquid that is directed to the flow control === the linear portion of the inflow into the edge, thereby offsetting the There is a transitional radius of the radius of the entire jet of ice that is not expected to deflect the steering.线性 Linear orientation can be advanced—fourth, in an advantageous manner, the radius of the connecting diversion steering surface forms an angle less than %. In (iv) the transfer of the sub-commission flow to better confuse other less-guided partial flows. [Embodiment] Figure 1 shows a scale squama (4) 1 which is advantageous in accordance with the present invention, including a diversion steering surface 2 located in the flow direction s of the liquid discharged by the nozzle arrangement of the sprinkler. In the preferred embodiment, the deflection surface 2 is formed at an angle to the longitudinal axis of the diversion steering. The diversion steering surface 2 is provided with a radially extending slot 3 which terminates at a distance from the isolated edge 4 AB of the deflecting diversion steering surface 2. It will be apparent that due to the groove 3 located at the diversion steering surface 2, the greater the distance of the AB, the greater the offset of the concentration of the liquid. In the preferred embodiment, the 'groove 3 is shown in such a way that its depth decreases as it extends radially toward the isolation edge and edge. In particular, in the advantageous embodiment shown, the depth profile of the groove 3 is chosen in such a way that it is divided into two regions 53 and 5b which are inclined differently. The area 5b$ that is furthest from the edge 4 is inclined. In order to optimize the transfer of liquid from the diversion steering surface 2 to the surrounding area of the sprinkler, the formation of the diversion steering surface 2 _ away from the edge 4 should be as sharp as possible. 2 is a top plan view of a diversion steering surface of the flow diverter of FIG. 1. A plurality of protrusions 6 that provide a lifting grip when the diverting steering gear is manually rotated are disposed around the circumference 201043340 of the diversion diverter i. The diversion deflecting surface defined by the isolating edge 4 is provided with a plurality of radially disposed slots 3. The sides 10 and 11 of the trough 3 are designed in such a way that their spacing increases as they extend towards the isolating edge 4. Furthermore, the transition from the sides 10 and 11 to the diversion steering surface is circular, which is particularly clear from the cross-sectional view of Figure 3. Figure 3 is a section through the area of the flow guiding surface 2 of the flow diverter 1 provided with the groove 3 and the stop portion 20 along the line AA. The arcs of the sides 1〇 and n of the groove 3 are particularly clear from the cross-sectional view. The transition between the diversion steering surface 2 and the stop 20 provided with the radius 21 will also be clearly visible. As can be clearly seen from FIG. 4, in the illustrated flow diverter, which synergistically combines all three alternative embodiments according to the invention in an advantageous manner, the stop 2 is divided into two angular offsets and Radially spaced linear portions 22 and 23. Only the transition from the diversion steering surface 2 to the linear portion 22 closest to the isolation edge 4 is provided with a radius. The two linear portions 22 and 23 are connected together by a connecting portion 24 having a relative to the diversion steering surface 2 The radius AR is less than an angle of 90 degrees. The invention is particularly applicable to the application of the patent specification No. DE 20 2007 014 407 U1 to the patent specification Fan Lin _ Confucian nozzle towel, which has a tree-like guide surface which is replaced by the flow guiding diverter of the present invention. The spray nozzle described in this novel type has a main portion in which a hollow linear portion is formed. The lower end of the linear portion is provided with an axially extending annular slot. According to the cover body described herein, the flow deflector 1 according to the invention can also be provided with a ring connector 10 at its lower end, which is designed as a linear body 11 and can be rotated into Hollow linear body of the main part. The lower portion of the ring connector 10 preferably has radial slots 13 which result in two halves of the symmetrical arrangement. In particular, the annular rib 12 is additionally provided at the lower end of the diversion steering 1, and it is clear from Fig. i that it has a larger diameter. Once the deflector diverter i is introduced into the main portion of the spray nozzle, the ring connector 10 is radially extended through the linear thread to extend to the extent of the annular rib 12, such that The ring ribs are movable in a ring slot forming a line. It is known from the test that the liquid flowing along the stop portion 20 is not directly and radially into the region around the sprinkler by the diversion steering surface 2 in an ideal manner, but partially deflected in the a direction, and the diversion steering surface 2 The radius AR forms an angle. This is indicated in the diversion steering gear! Already with respect to the spray nozzle part of the paving section, the full-duty (four) spray pattern 8 201043340 has been produced. The spray pattern that completely surrounds the sprinkler is typically produced when the deflector diverter has rotated an angle of about 355-358 degrees. Therefore, if the flow diverter 1 is used in a conventional spray nozzle, for example, German Patent No. DE 20 2007 014 407 U1, the annular rib 12 formed on the flow deflector can be arranged on the ring connector 10, whereby One way such that the annular rib 12 interferes with the annular insertion formed on the linear portion of the body before the flow diverter 1 has rotated a full 360 degree angle, preferably after a rotation of about 355-358 degrees. Stop at the top of the slot. This prevents a full 360 degree rotation of the diverting diverter 1 and thus ensures that the spray pattern has no overlapping areas, providing excess liquid in an undesirable manner.
