Description

PUR PIPE CLAMP

The invention relates to a clamp for pipelines, the parts of which are adapted in their shape to that of the pipelines and with the interposition of a seal by means of screws or the like. are attached to each other.

There are pipe break sealing clamps, tapping clamps and valve tapping saddles - also known as bridges. These serve to seal broken pipes or branches from already laid Manufacture pipelines. The known clamps all consist of an upper and a lower part. The lower part serves as an abutment for the upper part and is usually formed by a steel bracket, a half-shell, etc., which adapts to the pipe outside diameter as well as the upper part. When put together, the upper and lower part make up the actual Clamp. The upper part serves the desired function,

to

i.e. in the case of a broken pipe clamp as sealing elements Exactly like the lower part, or in the case of tapping saddles and valve tapping saddles, the mounting of the tapping or valve tapping devices.

These known clamps have the major disadvantage that they require a comparatively large amount of stock, since a different clamp size is always necessary if the pipeline is made of pipes of different materials, however same nominal size. Water pipes are for example with pipes made of cast iron, steel, asbestos cement and plastic relocated. The fittings required for this have so far been made in different sizes because they are the same Nominal sizes the outer diameters of the pipes are different and the mounting clamps are therefore only for one Size can be used.

Proceeding from this prior art, the invention is based on the object of providing a clamp for pipelines of the above-mentioned to create mentioned type, which is easy to manufacture and attach and a universal use as Sealing tapping and valve tapping saddle allows, with above In addition, the clamp can also be used for pipes made of different materials but the same nominal widths.

According to the invention, this is achieved in that the clamp consists of three parts, each with an area of about 120 Angular degrees are assigned and assigned to one another

Front sides mounting flanges or the like. exhibit. One like that trained clamp can be used in conjunction with the inserted seal as a pipe rupture sealing clamp, or but with a correspondingly adapted part of the clamp as a tapping clamp or as a valve tapping clamp Find. There is a certain amount of play between the individual parts of the clamp, so that they fit the different external can adjust the diameter of the pipes, which have the same nominal width.

The mounting flanges or the like. are of ribs or the like. held, which merge into the edges of the clamp parts, so that there is an overall very stable construction. In the Mounting flanges or the like. holes are provided, which are penetrated by screws, so that the individual parts of the Clamp can be clamped tightly together, with the inserted seal pressed against the surface of the pipes.

The seal with a stopper or the like is advantageous. equipped, which can be removed from the seal when used as a tapping or valve tapping saddle.

A part of the clamp is advantageously designed as a tapping clamp or valve tapping clamp, the other two parts of the clamp being of identical design.

An embodiment of the invention is based on the drawing

explained in more detail, namely :: -, eigt:

Fig. 1 is a view of the clamp according to the invention, Fig. 2 is a view of the clamp according to the invention,

However, with a tapping part and FIG. 3 is a view of the clamp according to the invention, but with a valve tapping part.

1 with the pipe is referred to, around which the seal 5 is placed is. The seal 5 is from the parts 2,3,4 of the clamp encompassed. The parts 2, 3, 4 are each an area of the pipe 1 assigned by about 120 degrees, so that they complement each other to a total of 360 °. Any fluctuations in the outside diameter of the tube 1, originating from different materials, can can be easily compensated, since between the parts 2, 3, 4 there is a space 6 in each case.

On the facing end faces, the parts 2,3,4 of the clamp are provided with fastening flanges 7, which are made of ribs 8 are held, which merge into the edges 9 of the parts 2,3> 4 of the clamp. This results in an extremely stiff one Construction. There are through-holes in the fastening flanges 7 10 provided for the fastening screws 11, of which only one is shown for the sake of simplicity.

As can be seen from FIG. 1, the parts 2, 3 »4 of the clamp 1 are

Dipl.-Ing. A. Spalthofi, patent attorney, 43 Essen - 5 -

identical to each other, differences in the outer diameters of the tubes 1, which depend on the material of the tubes are, without further ado, about the elasticity of the seal 5 on the one hand and the spaces 6 between the end faces of the (parts 2,3,4 can be compensated. With the same nominal widths of the pipes 1 it is therefore only necessary to have one size of clamps in stock.

The clamp according to the invention encompasses the pipe 1 like a bandage and thereby prevents pipe ruptures, for example can arise when drilling. Such breaks occur, as practice has shown, with the known ones with steel brackets provided valve tapping saddles. Furthermore, the invention offers the possibility, for example, of a house connection to provide a larger nominal diameter without, as previously necessary, a blind clamp on the existing hole in the pipe to put. As a result of the bandage-like encompassing the conduit by the clamp according to the invention, this can old hole sealed with part 2 or 3 or drilled open by the designs according to FIGS. 2 and 3. The conduit is supported with the help of the wide clamp that, contrary to the known embodiments, even a reinforcement of the pipe is reached in the tapping cross-section.

As can be seen from Fig. 2, a part of the clamp can be a modified one Have embodiment, namely - as shown, the part 2 have a projection 12 so that the clamp a Represents tapping clamp. In this version, the sealing

device 5 a. Plug 13 provided, which dea when drilling Tube is removed.

In the embodiment according to! 3, part 2 of the clamp is equipped with a housing 14, which is used as a valve tapping part serves.

Both tapping part 12 and valve tapping part 14 are per se known, so that these are not shown and described in detail to avoid repetition.
