Connection element for connecting a heating element ■ to a heating pipeline

The present invention "relates to a connector for connecting a heater to a heater · ^ pipeline, you "particularly refers to a prefabricated one Connection element which can be installed in • a heating pipe with forced heating fluid flow and a quick and easy connection of the heating element allowed as bypassing the main heating line, and zv / ar especially in a single-line heating system.

Such central heating systems are widely used today for heating apartments and ariderenüebäuden. . Building is generally done in two stages, namely:

a) Kinbau the main pipeline through all rooms in which one or more radiators can be connected after. Completion of the shell. Ü-lei early to this In the main pipeline, provide for the branches leading to the connection of radiators airman.

b) Connection of the radiators to these branches after finishing the fine work, such as laying the electrical cables, laying parquet floors, kacherboards, etc. ^r .

The branches mentioned above consist in that the main pipeline is drilled and that in this opening A pipe with a smaller diameter is welded in perpendicular to the main line. Depending on the care with which this Work 'are carried out, these branch pipes project more or less into the main line and thereby interfere the heating fluid flow is considerable. As a result, we '"question the proper functioning of the heating system posed.

The distance between two branch pipes is also determined by the length of the heating element. Hence os Later no longer possible, another heater Length to be connected without ugly connecting elbows.

The object of the present invention is to overcome these disadvantages to clear out.

To solve this problem, the invention brings a connection element of the type mentioned in the proposal, which is characterized in that it has two mechanically interconnected Comprises pipe bends, each of which a first jinde is intended for connection to the heating pipeline and a second end for connection to the heater body and that the pipe elbows with each other through a connecting line which are connected to such ofcolle to the pipe elbow assumes that with free flow through the igen Heating body the flowing! Liquid at least to the l'eil barking past the port.

In an embodiment of the invention it is provided that the connecting line has at least one throttle point. It is advantageous.,. if ever a throttle point to the Connection points of the connecting line to the elbow are provided. Then it is also useful that the Connection line establishes the mechanical connection between 'the pipe elbows. For a prefabricated production It is advantageous according to the invention if the first ends of the pipe bends are straight with each other and with the the connecting line. It is useful here that S the pipe elbows in a common plane and that the elbows are 90 elbows.

Further details and advantages of the invention emerge from the following description in connection with the accompanying drawings. The drawings show:

Fig. 1 shows a connection element according to the invention in Side view.

Fig. 2 shows a connection element according to the invention in a side front view.

Pig. 3 is a schematic sectional view taken along line 3-3 of Pig. 2.

Pig. 4 similarly shows Pig. 3 shows another embodiment of the invention.

Fig. 1 shows a prefabricated connection element according to the invention 2, comprising on the one hand a straight pipe section 2a and on the other hand two bends 2b and 2c.

The bends 2b and 2c are each welded to the ends of the pipe section 2a serving as a connecting line in such a way that that the ends of the pipe bends are aligned with each other and with the straight pipe section 2a and are in the in Pig. 1 type shown extend.

Each bend 2b and 2c has in the intersection area with the pipe section 2a a breakthrough 3, through which each Elbow is connected to the straight pipe section 2a. The openings 3 are calibrated in their cross-section and allow the heating fluid to flow into the pipe section 2a. With this you form a bypass line with a given charge loss, and this bypass always exists regardless of whether the radiator is in operation or not.

The installation of the connection element according to the invention is very simple. Do cut out or when laying the main line 4, the connection element 2 is welded in the plane of the radiator 5.

The connection of the radiator 5 after the fine work, such as laying the floor 6, is also very easy.

Because the connection elements according to the invention can be prefabricated in a workshop, the distance can between the free ends of the bends 2b and 2c and their height can be precisely determined.

The curvature of the bends 2b and 2c shown in the drawings results in a more favorable flow and passage the heating fluid is achieved perpendicular to the main line than with conventional connecting pipes.

For the same reason it is no longer necessary with a connection element according to the invention in heating systems, to lay the heating pipes inclined to facilitate the drainage of the heating fluid * · -

The connection element 2 according to the invention enables central heating in a rational and economical manner relocated, eliminating the need for central heating also becomes easier and no longer by highly qualified Must be carried out by skilled workers.

By prefabricating the connection element according to the invention, great dimensional accuracy is also ensured. The inventive The connection element can also be installed vertically, horizontally or at an angle in the floor, ceiling or masonry. Dimensions and shapes can be adapted to the special requirements.
