Pipeline distributors, in particular for hot water heating

The invention relates to a pipeline distributor for supply and return lines, in particular for Hot water heaters, with one in the longitudinal direction through a wall in a lead room and one Return chamber divided elongated distributor housing and with from the flow chamber and the return chamber outward pipeline connections.

Pipeline distributors of the type mentioned above have already been proposed and by the DE-PS 21 16 982 known. With this well-known pipeline distributor, which is excellently suited the pipe connections have the same diameter as the distribution line to be connected dependent length adapted to standardized system parts and are preferably used as reducing attachments designed in which the line cross-section gradually increases to different standard cross-sections in specified and adapted to other standard dimensions distances from the pipe section is reduced.

The invention is now based on the object of a pipeline distributor, especially for smaller ones To create heating systems, in which the production of the pipe connections is simplified and the Conversion to different diameters of the connecting pipes are simplified.

The object set is according to the invention with a pipeline distributor of the type mentioned at the beginning solved in that the pipe connections have a uniform length and uniform diameter and for the releasable anchoring of pre-fabricated different reducers specified

Length are formed. Advantageously, the pipe connections can be internally threaded sleeves welded to the distributor housing and the reducers on both sides have external thread sections with different diameters and have in between a conical reduction area and an attachment area for a tool. Further Advantageous features of the subject matter of the invention are listed in the subclaims.

Due to the tense energy situation, even with smaller heating systems, for example through the additional use of heat pumps and solar systems, additional pipe connections or Changes to the pipe connection distribution on pipe distribution systems required. These hatreds are facilitated by a pipeline distributor designed according to the invention. In the uniform formed pipe connections of the pipe distributor can optionally be different Use reducers that connect to a flow or return pipe of any diameter allow. By designing the parts as screw connection parts, rapid assembly is guaranteed and the connections can also be easily loosened again if necessary. When combining existing Heating systems with additional heat generators, which have to be connected together, occurs more frequently than also expects a redistribution of the pipeline connections

which can easily be carried out on a pipeline distributor designed according to the invention leaves.

An exemplary embodiment of the subject matter of the invention is described below with reference to the enclosed Drawing explained in more detail, with a partial longitudinal section through a pipeline distributor shows some pipe connections and various reducers.

The drawing shows a distributor housing 10 with a rectangular or square cross-section, which by an inner wall running in the longitudinal direction into a flow space 12 and a return space 13 is divided. The housing 10 can have a structure as described in patent specification 21 16 982 is described. On the top of the distributor housing 10 are openings at regular intervals formed, into which pipe connections 14, 15 and 16 formed as internally threaded sleeves are welded are all of the same diameter. Every second internally threaded socket is through the flow space 12 passed through to an opening 17 in the inner wall 11, thus forming a pipe connection to the return space 13, while the adjacent pipe connections 14, 16 connections to the flow chamber of the distributor housing 10 form. In the drawing are

another lateral flow pipe connection 18, a smaller pipe connection 19 for a drain line and a lower return pipe connection 20 drawn.

In the Rohrleltungsanschlüs se various reducers can be used, three of which are shown in the drawing. A first reducer 21 is arranged above the pipe connection 14, a second reducer 22 above the pipe connection 15 and a third reducer 23 above the pipe connection 16. All reducers 21-23 have at their lower end an external thread section 24 which fits into the uniform internal thread of the pipe connections 14-16 and which has an annular groove into which a sealing ring 25 is inserted. At the ending in an A _u ß _ _en flange 26 externally threaded portion 25, a tool extension region joins 27, which is polygonal in the illustrated reducers for the attachment of a wrench. The tool attachment area could, however, also be designed to be cylindrical and with a longitudinal fluting for the attachment of pipe wrenches.

Each of the three reducers 21, 22, 23 has an externally threaded section 28, 29 or 30 at its upper end which is found under the individual reducers

differs in diameter and allows the connection of different standard pipes. Corresponding the different diameters of the upper external thread sections 28,29 and 30 also has the conical connection area 31 »32 or 33 of the individual Reducers 21-23 between the tool attachment area 27 and the upper external thread sections 28, 29 and 30, different taper. Also the upper external thread section 28, 29 or 30 can be fitted with a sealing ring in a manner not shown.

The length of the reducers 21,22,23 can be the same or as a function of the connecting pipe diameter be different that when using commercially available or standardized Muffenabsperrorgane the spindle height of these organs in all parallel connecting pipes which is the same.
