Abstract

spraying unit characterized in that a frame (1) in the Way is done by putting in its upper area Ring (2) for centrally receiving a nozzle (3) arranged is, with an internal thread (16) for receiving the adapter (9) integrated is.

Description

The The invention relates to a spray unit, which with a Adapter is equipped, and for spraying or sprinkling large areas with liquid medium use place. Be useful for Flächenbesprühung by means of the spray units according to the invention several devices are used simultaneously, with the spray units are constructed by an adapter for connection with each other is mounted between them, or on the spray unit is screwed on. The adapters are used in areas where which pipes with existing recesses in the form of holes Branches for distribution and spraying of liquid Media needed.

So far Various sprayers are known which essentially characterized by having a Create spray cone, but the spray radius less fails and thus increases the number of spray units increased, or not the entire wetting surface is sprayed. In addition, in the area to be sprinkled no uniform spraying achieved. In addition to the spray units themselves are so far different adapters known, which are mainly by the locking on the pipe and differentiate the installation effort. Therefore, there is outside mounted adapter, which by means of arranged in the pipe additional Fastening holes are equipped and by means of screws and nuts are attached to the pipe itself.

Farther Adapters are known which are simply welded to the pipes which, however, is the case with existing fittings made of plastic materials prohibited for safety reasons.

Furthermore Other adapters are known in which by a in the hole the thread to be introduced is screwed onto the spray unit.

With the DE 33 34 749 Furthermore, the solution of a spray nozzle is known in which a conical spray is generated in a small, or small spray cone.

Finally, with the DE 694 15 482 Yet another solution of a spray unit known whose operation is in a pressureless water system and the spraying is done by means of a water distributor.

The previously known spray units together with adapters adheres thus the disadvantage that on the one hand a small spray cone arises with a low spray radius, and further the Spray cone no uniform wetting cause the sprinkler surface. This will be a one higher number of spray units needed and on the other hand, the individual spray units work ineffectively. Furthermore, the adapters are disadvantageous, a very to require complicated assembly as well as work preparation which is negative on the installation time and thus on the costs knock down.

The Invention is therefore the task of a spray unit with adapter that is simply constructed, reliable works and is inexpensive to produce and by can be mounted low mounting costs. With the invention Spray unit should also be a finer and more accurate nationwide Sprinkling of the surfaces to be sprayed possible be. The problem is solved by the characterizing Part of claim 1 indicated technical features.

The Nature of the spray unit according to the invention consists in a unit of several individual parts, in the upper Area a ring arranged to centrally receive the nozzle is. Furthermore, an internal thread for receiving the adapter and provided for locking the nozzle. The spray unit is constructed in the way by using a four-stage spray unit represents, which by differently dimensioned, down in the Diameter tapered spray plate distinguishes. Take the three arms combined at the bottom in coordinated intervals, the individual spray plates on. By the rejuvenation of the individual spray plates a multistage cone of fluid is created, which produces a uniform, holistic wetting of the sprinkling surface allows. The three upper spray plates are centered with an opening provide the water distribution in the lower area guaranteed. In the lower part forms the connected with the arms spray plate the mean drop formation of the liquid to be sprayed Medium.

By different partial diameter and their coordinated arrangement is produces a cone of liquid medium, its irrigation evenly is divided to the entire sprinkler fish.

The adapter is first inserted at its partly flattened side in a receiving tube and hooked by means of two-sided tabs. With the approach of the molding adapted to the respective pipe diameter, the adapter is locked and screwed by means of preferably a knurled nut. The peculiarity of the adapter is finally in the vote between the outer diameter of the adapter and the opening in the receiving tube, the difference is only a minimum difference and in terms of size only about one milli meter, or amounts to, and thus designed almost form-fitting.

The Invention will hereinafter be an embodiment be explained in more detail. In the associated Drawings show:

1 : a spray unit

2 : an adapter

3 : a molding

4 : Cut knurled nut

5 : first spray dish

6 : second spray dish

7 : third spray dish

8th : Pickup tube

9 : Adapter

The essence of the adapter according to the invention 9 consists in the vote between the outer diameter of the adapter 9 and the opening of an outer tube 19 , wherein there is only a minimum difference of about one millimeter, and thus almost a positive engagement of both parts is achieved. A spray unit faces the adapter 9 the second module of the whole unit. It consists of a frame 1 , in the upper part of a ring 2 is arranged, which with an internal thread 16 is equipped to the nozzle holder. A nozzle 3 is designed as a change nozzle with different diameters. Furthermore, the spray unit has arms 4 for holding the spray plate 5 ; 6 ; 7 and 8th , Finally, the spray unit is in different levels just with a first spray plate 5 , a second spray dish 6 , a third spray dish 7 and a fourth spray dish 8th connected in the form of a rake. The spray dishes 5 ; 6 and 7 are here with distribution openings 15 fitted. The adapter 9 has at its periphery an external thread 10 on, with which he is bolted to the spray unit. The adapter 9 is also with a molding 17 equipped and a knurled nut 18 has an internal thread, which matches the external thread 10 of the adapter 9 is trained. The adapter 9 gets into a pickup tube 19 on tabs 14 mounted, which by means of a flattened side 11 and an upper chamfer 12 and a lower chamfer 13 on the adapter 9 is arranged.
