WRRM / KRLT WATER DISTRIBUTOR

The invention relates to a hot/cold water distributor for sanitary and heating installations.

In the plumbing and heating installation industry, distributors made of different materials are usually used as hot/cold water distributors. These distributors enable the flow of hot or cold water to several consumer connections.

Known designs of these distributors essentially consist of a tubular base body to which threaded connections are attached on both sides in the axial direction. There are usually several additional threaded connections arranged radially around the circumference of the base body, which are designed for one type of connection.

Preferably, the radial threaded connections of a plane are arranged in pairs.

The known solutions consist primarily of brass or gunmetal.

The distributors are usually attached to the supply line using a union nut via one of the two threaded nozzles attached to the front in the axial direction.

Distributors of this type are described, for example, in DE-GM 92 02 200.6 and PS - FR 22 59 310.

The threaded nozzles are sealed in the base body.

The disadvantage of this solution is that the external threaded nozzle must be sealed. Such sealing, for example by gluing or hemping the nozzles, is technologically complex.

A further disadvantage is that the threaded connections are only fixed to one type of connection.

The invention is based on the task of developing a hot/cold water distributor that enables connection to the supply line by means of a union nut without sealed threaded nozzles and offers variable connection options.

This object is achieved according to the invention in that a hot/cold water distributor - Fig.l - for use in sanitary and heating installations, consisting of a tubular base body (1) with several radially arranged threaded connections (4), a further threaded connection (5) attached in the axial direction and an opposite connection by means of a union nut (2), is modified in such a way that a cylindrical pin (6) with a semicircular groove is attached to the distributor inlet, the line connection is carried out by means of a union nut (2).

which is secured by a snap ring (3), the union nut (2) contains a groove as shown in -Fig.2-, the diameter (D) of which is greater than/equal to the pin diameter (dl) plus 2 times the wire diameter (d2) of the snap ring (3).

The groove in the union nut is designed as shown in Fig.3.

Furthermore, the threaded connections are provided with a cylindrical external thread as shown in Fig. 4, whereby the threaded connections can also be provided with a cylindrical internal bore.

The advantages achieved with the invention are in particular that by replacing the external thread nozzle, technological simplifications are achieved by eliminating the additional gluing, material savings by eliminating the external thread nozzle and shortening the overall length of the distributor.

The design of the threaded connections enables the connection of flat-sealing connections as well as compression fittings for PE pipes.

An embodiment of the invention is shown in the drawings - Fig. 1-5 and is described below.

The distributor shown in Fig.l is a distributor for hot and cold water made of brass or gunmetal. The movable union nut (2) is attached to the base body (1) using a snap ring (3), whereby the snap ring (3) is mounted with the union nut (2) in such a way that the snap ring (3) is no longer visible from the outside after assembly.

The groove of the union nut (2) is designed in such a way that the snap ring (3) can be installed in it and when screwed on, the snap ring (3) is pressed into the groove on the distributor socket. This means that the union nut (2) can rotate freely in the radial direction on the socket of the distributor, but cannot be removed and cannot be moved axially due to the snap ring (3).

The rotating union nut (2) ensures that the necessary tightening torque is applied to achieve a tight seal between the line and the distributor.
