Description

The Invention relates to a distributor fitting for domestic water installations, in which two or more branch tee valves are arranged side by side are.

distribution valves of the type mentioned are, for example, from the product range of Company Bender Armaturen GmbH & Co. KG (57368 Lennestadt-Grevenbrück) known. They serve different supply circuits of a domestic water installation to connect to a central domestic water intake while keeping it at the same time to be separable with a valve separately from the termination.

at The known distributor valves, a connecting pipe is solid Length with an external thread and a flat-sealing end with union nut to an internal thread or external thread of screwed two adjacent branch T-valves, if this is the Row after connected to the water supply. adversely It is because of the distance between the branch T-valves the length the connection tube is fixed. Therefore, there are also distribution valves, where the connecting pipe is a continuous external thread has, so that it can be cut to a suitable length if necessary. In addition to the effort for the Shorten is at this solution continue the workload for a new deburring and sealing the sawn end in each port of the branch tee valve disadvantageous. Furthermore, the connecting pipe unusable if accidentally cut short.

In front this background, it was an object of the invention, one with low Effort-mountable distributor fitting for domestic water installations providing a variable positioning of the branch tee valves allows.

These The object is achieved by a distributor fitting with the features of the claim 1 solved. advantageous Embodiments are included in the subclaims.

• a) Ein erstes Abzweig-T-Ventil mit einer Verbindungsverschraubung in Form eines Auslassstutzens, welcher typischerweise als ein zylindrisches Rohrstück ausgebildet ist. Die Fließrichtung des Durchflussmediums ist variabel.
• b) Ein Verbindungsrohr mit einem ersten Ende, welches im Folgenden "Steckende" genannt wird und welches mit variabler Tiefe in oder auf den vorstehend genannten Auslassstutzen des ersten Abzweig-T-Ventiles gesteckt werden kann. Typischerweise ist das Steckende des Verbindungsrohres außen zylindrisch mit einem Durchmesser, welcher dem Innendurchmesser des Auslassstutzens entspricht. Das Verbindungsrohr ist vorzugsweise gerade, kann jedoch optional auch Krümmungen enthalten.
• c) Eine Klemmeinrichtung zur (axialen) Fixierung des Verbindungsrohres am Auslassstutzen.
• d) Ein zweites Abzweig-T-Ventil mit einem Einlassstutzen, welcher mit einem zweiten Ende des Verbindungsrohres verbunden ist oder verbunden werden kann. Auch beim "Einlassstutzen" ist die Bezeichnung entsprechend einer möglichen bzw. typischen Wasserdurchflussrichtung gewählt, ohne dass hiermit jedoch irgendeine Einschränkung technischer Art verbunden sein soll. Das Verbindungsrohr kann optional auch fest mit dem Einlassstutzen des zweiten Abzweig-T-Ventils verbunden sein, beispielsweise als dessen einstückige Verlängerung.

The distributor fitting according to the invention for domestic water installations comprises the following components:

• a) A first branch T-valve with a connection fitting in the form of an outlet, which is typically formed as a cylindrical tube piece. The flow direction of the flow medium is variable.
• b) A connecting tube having a first end, which is hereinafter referred to as "plug-in end" and which can be inserted with variable depth in or on the above-mentioned outlet of the first branch T-valve. Typically, the male end of the connecting tube is externally cylindrical with a diameter corresponding to the inner diameter of the outlet nozzle. The connecting tube is preferably straight but may optionally also include bends.
• c) A clamping device for (axial) fixation of the connecting tube at the outlet.
• d) A second branch tee valve having an inlet port which is connected or connectable to a second end of the connection tube. Even with the "inlet nozzle" the name is chosen according to a possible or typical water flow direction, without this, however, should be associated with any restriction of a technical nature. The connecting tube may optionally also be fixedly connected to the inlet connection of the second branch T-valve, for example as its one-piece extension.

The described distributor fitting has the advantage that the distance between the first and second branch tee valves in certain Limits can be varied by connecting the connecting pipe accordingly far into or on the first branch T-valve plugged and then with the clamping device is fixed. A time-consuming sawing off and new sealing of connections is thus eliminated.

Preferably the first and the second branch tee valve have the same design, so they both in particular each have an inlet nozzle and a Include outlet with the described properties. Out such branch tee valves then with the help of a corresponding number of connecting pipes produce a quasi arbitrarily long series of branch T-valves.

optional The second end of the connecting tube can also be used as a plug-in end be formed, which with variable width in or on a corresponding trained inlet socket and with an associated clamping device can be fixed there. To the distance between two branch T-valves however, it is not necessary Provide variable insertion depths at both ends of the connecting pipe. Preferably, therefore, the second end of the connecting pipe with provided an external thread, which in a complementary Internal thread of the inlet port of the second branch T-valve can be screwed. In this case, a simple, conventional screw connection a firm connection between the connecting tube and the second Branch T-valve getting produced. Advantageously, this connection is included sealed by a sealing ring or the like against leakage of water.

The Connecting tube preferably has key surfaces to the neck of a wrench to allow. This is especially useful if its second End screwed as described above in an inlet socket can be.

For the insertion depth there is typically one of the mating end of the connecting tube permissible Area, which must not be left, so that the connecting pipe not too deep in the first branch T-valve plugged or closed is pulled out of this far. To ensure compliance with the permissible insertion depth to be able to control better, the connecting pipe preferably has corresponding ones on its outer surface Markings on.

According to one another variant of the invention, the connecting pipe at its Outer surface at least a thickening, which as Einschubbegrenzung or Ausziehbegrenzung serves. In this way it can be prevented that the connecting pipe accidentally too deep into the outlet port of the first branch tee valve is pushed in or pulled out too far.

For the design There are various possibilities of the clamping device. Preferably she a union nut on which on an external thread the outlet can be screwed on.

• – eine elastische Dichtung, z. B. ein Gummiring;
• – ein Pressring, welcher für eine gleichmäßige Druckbelastung einer Dichtung sorgen kann und diese vor Beschädigung schützt;
• – ein offener Klemmring mit einer radial außen liegenden konischen Stirnfläche, wobei die Öffnung bzw. Schlitzung des Klemmringes erlaubt, dass dieser zusammengedrückt und damit im Radius verkleinert werden kann;
• – ein Konusring mit einer radial innen liegenden konischen Stirnfläche.

In the above case, at least one of the following elements is further arranged between the union nut and the end face of the associated outlet nozzle:

• - An elastic seal, z. B. a rubber ring;
• - A press ring, which can provide a uniform pressure load on a seal and protects it from damage;
• - An open clamping ring with a radially outer conical end face, wherein the opening or slit of the clamping ring allows it to be compressed and thus reduced in radius;
• - A cone ring with a radially inner conical face.

In Cooperation with the radially outer conical face of the open clamping ring causes an axial compression of clamping ring and conical ring, that the clamping ring is pressed radially inward and therefore on the outer circumference biting the connecting pipe.

in the Below, the invention with the aid of the accompanying figure exemplified.

The figure shows in a cross section a distributor fitting according to the invention with three similar branch T-valves 10 . 10 ' and 10 '' , which each have two connecting pipes 20 . 20 ' connected to each other. It is between the left two branch T-valves 10 and 10 ' set a minimum distance of, for example, 129 mm, while between the two right branch T-valves 10 ' and 10 '' a maximum distance of, for example, 154 mm is set. The distance between two branch T-valves can thus be infinitely varied over a range of 25 mm.

The branch tee valves each have an inlet port 13 . 13 ' with an internal thread over which enters water from a domestic water supply in use. The water in the branch T-valve on the one hand straight to an opposite outlet 14 passed to the other in an upward branch 12 to which a circuit of the domestic water installation is connected (for example, a building floor). This circuit can be via a shut-off valve 11 if necessary be disconnected from the house water supply.

In many cases, especially when retrofitting distribution fittings, the axial (horizontal in the figure) distances between the terminals of the individual supply circuits are already fixed. The positions of the branch T-valves 10 . 10 ' . 10 '' then have to adapt to these requirements, which is particularly easy with the illustrated system. The distributor fitting contains connecting pipes for this purpose 20 . 20 ' with a first end, the so-called plug-in end 21 , with variable depth in the outlet 14 the branch T-valves can be inserted. The opposite second end of the connecting pipes 20 has an external thread 24 on, with which it in a korrospondierendes internal thread of the inlet nozzle 13 . 13 ' can be screwed. A sealing ring 25 ensures a suitable seal. Furthermore, the connecting tubes preferably have key surfaces 23 on, on which a wrench can be attached.

• – eine Überwurfmutter 15, durch welche das Verbindungsrohr 20 hindurchpasst und welche auf ein Außengewinde des Auslassstutzens 14 aufgeschraubt werden kann;
• – einen elastischen Dichtungsring 16, welcher vor dem Stirnende des Auslassstutzens 14 liegt und bei Anziehen der Überwurfmutter 15 zusammengequetscht wird, so dass er für eine entsprechende Dichtung sorgt;

• – einen Klemmring 18, welcher entlang seines Umfangs einmal geschlitzt ist, um im radialen Durchmesser veränderlich zu sein; des Weiteren weist der Klemmring an seiner in der Figur rechten Seite eine radial außen liegende Konusfläche auf;
• – einen Konusring 19 mit einer an seiner in der Figur linken Seite radial innen liegenden Konusfläche; beim Festziehen der Überwurfmutter 15 werden die Konusflächen von Konusring 19 und Klemmring 18 in axialer Richtung aufeinander zu gedrückt, so dass der Klemmring sich radial einwärts bewegt und dabei auf der Außenfläche des Verbindungsrohres 20 festbeißt.

For axial fixation and sealing of the plug-in end 21 in a desired insertion depth serves a clamping device, which comprises the following components:

• - a union nut 15 through which the connecting pipe 20 passes through and which on an external thread of the outlet 14 can be screwed;
• - An elastic sealing ring 16 , which in front of the front end of the outlet 14 lies and when tightening the nut 15 squeezed together so that it provides for a corresponding seal;
• - a press ring 17 , which the pressing pressure on the rubber ring 16 transfers;
• - a clamping ring 18 which is slotted once along its circumference to be variable in radial diameter; Furthermore, the clamping ring on its right side in the figure on a radially outer cone surface;
• - a cone ring 19 with a conical surface lying radially inwardly on its left side in the figure; when tightening the union nut 15 become the conical surfaces of cone ring 19 and clamping ring 18 pressed in the axial direction toward each other, so that the clamping ring moves radially inwardly, while on the outer surface of the connecting pipe 20 firmly bites.
