Furthermore, the invention must be a Easy handling when replacing the sealing insert possible with new as well as with existing water fittings lichen. It is desirable to attach a fuse that the inflow of sand, stones and other hard counter stands avoided. Last but not least, the invention must be one represent simple construction of a sealing insert, whose lifespan complies with the applicable standards in the field of Water sanitary fittings corresponds.

State of the art

The technical problem described is solved by known solutions in different directions. The basic problem which is to be solved by water for saving measures is the Reduction of water drainage with the maximum open ven til the water tap. Water fittings of the well-known Kon Structures are too economical for the basic versions not determined. The amount of water flowing out is depending on the opening level of the valves of such Armatu Ren. Especially with large consumers, it is very difficult to to achieve a rational consumption. These are constructive Known solutions that even with the valve open to the maximum Avoid maximum discharge. Such are e.g. Legs Solution in which an attachment is screwed to the tap which prevents the maximum outflow and equal allow the water to be mixed with air (aerator) at an early stage light so that a wide, even beam is reached becomes. This version does not solve the technical problem, because the approach in terms of reducing the runoff Water tap claims damage is exposed. With this there is still the possibility unscrew the approach.

Constructions described in DL 1 20 694, BE 8 51 162 and SU 4 64 752 are described, only solve be is the technical problem of reduction of water drainage. They also have several shortcomings.

So z. B. for the design solution described in the patent document SU 4 64 752 is described, entangled sensors elements necessary. Because of this, the well-known Execution can not be easily installed and is for general use at the individual acceptance not suitable.  

Other types of solutions that reduce water runoff are in the patents DE 25 10 973, BE 8 54 884 and US 40 44 991 described. They work on the principle sliding bar with which the flow is reduced or can be enlarged, so at individual parts of the What pipeline network or at different tapping points.

These solutions are also for a perfect satisfaction application of the technical problem applicable with the application elements lying in the tolerance field, which are light can be damaged and the easy replacement complicate. Such an application must already be in the project be provided as the subsequent installation is not always is possible.

All solutions described can be in the sense of technical Protection of water fittings problem do not satisfy against contamination.

Description of the solution

A sealing insert for controlled water drainage according to this invention solves the technical problem in one Way that in the pressure part of the connection between the tube and the water fitting the sealing insert is inserted, the seal part of the dimensions of normal seals corresponds, with the middle part with the conical network element and flow element is connected. This is with one or more through holes with one-sided Provide lowering.

The invention is described below with reference to the attached drawing for example described in more detail; it shows  

Figure 1 is an illustration of an embodiment of the application of the sealing insert for a CONTROL profiled water drain according to the invention in section;

Figure 2 shows a sealing insert for a controlled water drainage according to the invention in section and in a side view, and

Figure 3 shows a seal insert for a controlled water drainage according to the invention in the view AA.

Figure 1 shows schematically an embodiment of the application of the sealing insert for a controlled What water drain according to the invention in the pressure part of an existing or newly built water supply network. The sealing insert is fastened on the tube 4 of the water pipe with the aid of a threaded nut 5 . At the outlet side of the Ge nut 5 , the water fitting is connected. From Figure 1, the position of the sealing part 1 with the through flow element 2 and the network element 3 can be seen.

Such an application of the sealing insert is only described by way of example and in no way limits the invention. It is conceivable to use the seal insert wherever normal seals have hitherto been used, since the seal part 1 according to the invention corresponds to a normal seal in terms of material and dimensions.

In pictures 2 and 3 the construction of the sealing insert for a controlled water drainage is shown according to the invention.

In Figure 2, a sealing insert for a controlled water drainage according to the invention is shown in section and in a side view. It can be seen the sealing part 1 , which includes the flow element 2 with the inner part, which can preferably be designed in disc form. The connection of the sealing part 1 with the flow part 2 must be carried out exactly, preferably by vulcanization. At the same time, part 3 of the vulcanization is connected, where it is firmly connected to part 2 by the flange-shaped end.

The flow element 2 has in the example centrally located bores 2 a with a depression 2 b. Such Ausfüh tion serves the controlled flow of water. At the same time, however, the lowering 2 b enables a low-noise flow of water. The dimensioning of the holes 2 a depends on the desired flow rate.

In the complex solution of the effluent, as at higher buil the (hotels, skyscrapers, ..), the flow elements 2 must be provided with different sized holes 2 a, systematically. Due to the flow requirements, several bores 2 a with different diameters can be made in several places.

The shape and installation of the network element 3 enable the fittings connected to the water network to be protected against dirt, which moves simultaneously with the water and causes damage to the fittings seats.

With the installation of the sealing insert for a controlled The water drain becomes the technical problem as a whole solved, whereby it is determined:

• - By eliminating the water consumption peaks, new ones Consumers are connected
• - The adaptation to a desired low Wasserver need regardless of the water pressure in the what supply line to the fittings is made possible light the same amount of water at all drainage points,
• - With the change of a built-in seal and adaptation of the cross-sections of the bores 2 a to the flow element 2 , in a short time and in a simple manner, a low water consumption, a higher stability and an impeccable maintenance of the water fittings are achieved,
• - With the sealing insert of the invention in use with a shower ensures that the nozzles do not become blocked,
• - At drainage points, the water flows through without foreign parts.

The invention relates to a sealing insert for a controlled water drainage, acting as a combined seal with a conical protective net and a flow element to reduce the water drainage in a pressure part new and existing water fittings are installed.

The sealing insert for controlled water drainage according to the invention reliably solves the posed techni cal problem in such a way that in the printing part of the An a seal between the tube and the water fitting insert is used, which regards the sealing part dimension and material compared to standardized Seals look alike, the middle part with a net and flow element is provided, the reduction takes over.  

In Figures 2 and 3, the construction of the sealing insert for a controlled water drainage according to the invention is shown, while in Figure 1 a possible embodiment is shown schematically with an attachment of the sealing insert in the pressure part of existing or new water pipes.
