Abstract

Tapping clamp tapping piece (1) with a tubular body (2) and with a sealed tapping end (6), characterized in that the tapping piece (1) is formed as a separate part, and that the tapping piece or its tubular body (2) has a clip-side end (5) for connection to a departure of a tapping collar.

Description

The The present invention relates to a tapping tee for connections between a tapping clamp and a Domestic connection line and a service line tapping connection system.

An Anbohrsystem for house connection lines is for example from the DE 102 13 803 A1 known. In this writing, as well as in the DE 101 24 239 C1 , A tapping sleeve shown, which has a very short lateral outlet, which is formed integrally with the tapping clamp and at the same time serves as a locked in the initial state tapping piece for the tapping clamp.

House connection systems with such tapping clamps serve the supply of houses with fluids, ie with gases or liquids (eg water). In the finished state of construction, they usually include an underground installation Main pipe from which a pipe into the basement of a house to there Distribution device leads. On the Anbohrabgang the at the main pipe attached tapping clamp follows according to the state the technology usually a house connection, in which also a shut-off can be introduced. To supply the house connection line for the first time, becomes through it a drill head up to a shutter disc at the tapping-branch outlet led to this shutter disc then drill and so the inflow of the fluid in to allow the house connection line.

It It is the object of the present invention to provide such service line systems to make it more flexible. This object is achieved by a tapping tee according to the Claim 1 and by a service line tapping connection system with such a tapping piece according to the Claim 9 solved. Advantageous embodiments The invention are defined in the subclaims.

The Tapping sleeve tapping piece according to the invention has a tubular body and a sealed tapping end on, wherein the tapping piece formed as a separate part is and the tapping piece or its tubular body a having clip-side end for connection to a departure of a tapping clamp.

With In other words, according to the invention, the tapping piece as a separate component or as an individual part independent of the tapping clamp, but provided for connection with this provided. This inventive separation of tapping clamp outlet and tapping piece makes house wiring systems very much much more flexible because, for example, different tapping clamps Can be used without the arrangement or connection changed from tapping piece and house connection line must become. Of course, can also be advantageously by different tapping pieces according to the invention, which can be configured in the manner of adapters, previously not connectable tapping clamps and service lines connect. The handling of the entire connection system is so more flexible and offers a larger Scope of application.

at an embodiment of the present invention are the Tubular body and its end closure made of a full polyethylene material basically, it should be noted that the invention in its widest version also on tapping pieces or connecting elements is applicable, the other materials, for example have metallic materials.

Of the End closure can be formed integrally with the tubular body be or as a separate connected to the tubular body, in particular welded, or connectable lid can be provided. It advantageously has at its end a substantially central drill centering recess on which the right, center Attachment of the drill head supported when opening the pipe.

at an embodiment of the invention Tapping piece is the jaw-end an open one Pipe end, and it may be as smooth or unprocessed or suitable for welding Pipe end are provided. But it is also possible the clip end with a pipe connector for connection to be provided with the tapping collar outlet, in particular with a sealed threaded connection or a sealed bayonet connection. Here are basically all pipe connection techniques in question, but they are not listed here individually have to.

The house connection line tapping connection system according to the invention has a tapping piece according to the present invention and therefore also has the advantages already described above. In such a system, the tapping piece may be connected at its tapping end via a welded connection to the service line, and it is also possible to connect the tapping piece at its clip end also via a welded connection with the tapping clamp. As already described above, all other threaded connections come into consideration, for example sealed threaded or bayonet connections, on the clip-side end (but also in principle on the plug-in end of the house connection). The welded connections or each of the welded connections can be used from the outside Ends of welding elements to be welded enclosing welding connectors, in particular a welding clamp include.

The The invention will be further described by means of embodiments and with reference to the accompanying figures closer explained. It can have all the features described herein individually and in any meaningful combination. In the drawings demonstrate:

1 to 3 a tapping tee according to the present invention in different views;

4 a connection system according to the invention with two welded joints on each side of the tapping piece; and

5 a connection system according to the invention with a welded connection at the house connection-side end of the tapping piece and another connection at the clip-side end.

An embodiment of a tapping tee according to the invention is in the 1 to 3 shown, the 1 an oblique view of the tapping piece 1 from the building connection end, the 2 an oblique longitudinal section view and the 3 shows an oblique view from the clip end.

The tapping piece 1 , which is constructed entirely of a polyethylene material in the present embodiment, comprises the tubular body 2 on, at his clip-end 5 simply forms an open pipe end. At the end of his house 6 is at the pipe twill 2 the lid 3 attached, in the present case fixed to the tubular body 2 is welded. Again, other connections can be selected such. B. connectors, especially rotatably configured connectors or threaded connections. Center is on the outside of the lid 3 a centering recess 4 trained, which can center the drill of a drill head, with which the lid 3 is pierced to make the flow connection.

The 4 and 5 Now show how the tapping piece according to the invention is embedded in a, in turn according to the invention, connection system between tapping clamp and house connection line. Here, all components are shown purely schematically.

Is common in the 4 and 5 the pipe 10 to see in cross-section, which is laid as a service pipe underground in the area of the road. It can be, for example, a fresh water pipe. On the pipe sits a tapping clamp 12 through whose body water from the pipe 10 in the finish 14 arrives.

By the nature of the connection of the on the departure 14 following tapping piece 1 with the finish 14 The embodiments of the differ 4 and 5 according to the 4 is the pipe body 2 of the tapping piece 1 with the help of a welding fitting or welding connector 16 at the departure 14 tension- and rotation-proof and fluid-tight. For this purpose, the clamp-side end of the tubular body 2 In particular, learn no changes in shape, it can be configured as an open pipe end and simply welded.

In the 5 is a more general connection case for the tubular body 2 and the finish 14 shown, wherein as a compound simply schematically a connection point 17 between this component is displayed. This connection 17 may be any known in the art pipe joint, in particular a sealed threaded or bayonet (closure) connection.

The one on the right side of the tapping piece 1 shown elements of the connection system are again in both versions of the 4 and 5 the same. At its house connection-side end has the tapping piece 1 the lid 3 on and it will with the help of the welding fitting 18 with the illustrated left-side end of the service line 20 again tensile and non-rotatable and fluid-tight connected. In addition, the connection point with the welding fitting or the welding connector 18 still by alignment elements (not shown) designed so that the service line 20 and the tubular body 2 after the weld joint are aligned axially, so that a drill head 30 at the end of a linkage or flexible shaft 32 sits, through the house connection 20 to the lid 3 can be performed. There he drives with the front end of the drill into the centering recess 4 ( 2 ), so that then the lid 3 can be drilled for the preparation of the flow connection. Thereafter, the drill head 30 removed again and the water supply can be provided via the service line.
