Abstract

The hydrant has a tube (1) with a valve housing at its lower end, and water outlets at its upper end. It also has a rod for operating the valve. The length of the tube and the rod can be adjusted, in order to position the level of the hydrant correctly. The equipments (3,4) for adjusting these lengths may be arranged at roughly the same level, and one or both of the equipments may be positioned below the predetermined breaking point (5) of the hydrant. The tube, or a section of it, may also have two parts (7,8) of different diameters. These two parts may be arranged telescopically.

Description

Die Erfindung betrifft einen Hydranten, bestehend aus einem Rohr, das mit seinem unteren Ende mit einem Ventilgehäuse verbunden ist, das an seinem oberen Ende Wasserabgabeelemente aufweist und in dem ein Gestänge angeordnet ist zur Betätigung des Ventils im Ventilgehäuse, wobei das Rohr beziehungsweise ein Rohrstück aus zwei Teilen unterschiedlicher Durchmesser besteht, die teleskopartig ineinander geschoben sind, wobei im in Gebrauchsstellung unteren Rohrteil eine Einrichtung zur Lagerung und Führung der Ventilschraubspindel angeordnet ist, die von oben aus- und einbaubar ist. The invention relates to a hydrant consisting of a Pipe that with its lower end with a valve housing is connected, the water discharge elements at its upper end has and in which a linkage is arranged for actuation of the valve in the valve housing, the tube or a pipe section made of two parts of different diameters exists, which are telescopically pushed into each other, in in the lower tube part in use position a device for Storage and guidance of the valve screw spindle is arranged, which can be removed and installed from above.

Beim Einbau von Hydranten an neu erstellten Straßen ergibt sich das Problem, daß zu dem Zeitpunkt, zu dem der Hydrant eingebaut werden muß, die Höhenlage des Hydranten nicht genau bekannt ist. Bei der Erschließung eines Geländes werden in der Regel zunächst die Wasserleitungen gebaut und erst anschließend die Straße. Erst im weiteren Ausbau bestimmt sich die endgültige Höhenlage der Straße und damit die richtige Höhenlage für den Hydranten. Jeder Hydrant sollte aber ausreichend exakt auf die Höhenlage des Straßenniveaus abgestimmt sein. Der Hydrant besitzt nämlich eine Sollbruchstelle die knapp oberhalb des Erdbodens liegen soll. Ist der Hydrant zu tief eingebaut, befindet sich die Sollbruchstelle im Erdreich bzw. in der Straßendecke. Sie kann ihre Funktion nicht erfüllen, da sie vom umgebenden Erdreich bzw. im Straßenbelag gehalten wird.When installing hydrants on newly created roads the problem that at the time the hydrant was installed must not be known exactly the altitude of the hydrant is. When developing a site are usually first built the water pipes and only then Road. The final one is only determined in further expansion Elevation of the road and therefore the correct altitude for the Hydrants. However, each hydrant should be sufficiently precise Elevation of the street level must be coordinated. The hydrant has a predetermined breaking point just above the Earth should lie. If the hydrant is installed too deep, the predetermined breaking point is in the ground or in the Road surface. It cannot fulfill its function because it is from surrounding soil or in the road surface is kept.

Wird der Hydrant zu hoch eingestellt, ist bei der Beschädigung auch mit Schäden unterhalb der Sollbruchstelle zu rechnen.If the hydrant is set too high, it is damaged damage to be expected below the predetermined breaking point.

Da die endgültige Höhenlage der Straße erst zu einem verhältnismäßig späten Zeitpunkt festliegt, ist es häufig notwendig, den Hydranten wieder auszugraben und zwischen die Anschlußstelle an der Versorgungsleitung und den Elementen, die dem Hydranten zuzuordnen sind, Zwischenstücke ein- oder auszubauen. Dies ist aufwendig.Since the final high altitude of the road only becomes one relatively late, it is common necessary to dig out the hydrant again and between the Junction on the supply line and the elements that the hydrant can be assigned to install or remove intermediate pieces. This is expensive.

Der Erfindung liegt die Aufgabe zugrunde, eine Anordnung zu treffen, mit der es möglich ist, mit geringem Aufwand den Hydranten in die richtige Höhenlage zu bringen. Ein weiteres Ziel besteht in der Vereinfachung der Wartung des Hydranten.The invention has for its object an arrangement meet with which it is possible with little effort the hydrant to bring them to the correct altitude. Another goal is to simplify hydrant maintenance.

Zur Lösung dieser Aufgabe geht die Erfindung aus von einem Hydranten der eingangs angegebenen Gattung, bei dem sowohl das Rohr als auch das Gestänge bezüglich seiner Länge veränderlich ist und bei dem eine Einrichtung zur Lagerung und Führung der Ventilschraubspindel im unteren Rohrteil in Gebrauchsstellung gesehen angeordnet ist und wobei diese Einrichtung von oben aus- und einbaubar ist. Erfindungsgemäß wird vorgeschlagen, daß der Hydrant eine Sollbruchstelle aufweist, wobei Einrichtungen zur Veränderung der Rohrlänge und der Gestängelänge in Gebrauchsstellung unterhalb der Sollbruchstelle angeordnet sind. Sie gelangen hierdurch an eine Stelle, bei der sie mit hoher Wahrscheinlichkeit bei einer Beschädigung des Hydranten unbeschädigt bleiben, so daß lediglich der bisherige Teil des Hydranten oberhalb der Sollbruchstelle auszutauschen bzw. zu reparieren ist. Die Längenveränderlichkeit des Hydranten läßt genügend Spielraum um Niveauunterschiede der endgültigen Straße ausgleichen zu können. Beispielsweise wird der Hydrant nach Fertigstellung der Straße etwas angehoben oder abgesenkt, um die gewünschte Lage insbesondere der Sollbruchstelle zu erhalten.To achieve this object, the invention is based on one Hydrants of the type specified at the beginning, in which both The length of the tube and the linkage are variable is and in which a facility for storage and management of Valve screw spindle in the lower pipe part in use position seen arranged and with this device from above can be removed and installed. According to the invention it is proposed that the hydrant has a predetermined breaking point, facilities for Changing the pipe length and the rod length in the position of use are arranged below the predetermined breaking point. she thereby get to a place where they are very likely undamaged if the hydrant is damaged remain, so that only the previous part of the Exchange or replace hydrants above the predetermined breaking point repair is. The length variability of the hydrant leaves enough scope for differences in level of the final road to be able to compensate. For example, the hydrant is after Completion of the road slightly raised or lowered to to obtain the desired position, in particular of the predetermined breaking point.

Günstig ist es dabei, wenn die Einrichtungen zur Veränderung der Rohrlänge und der Gestängelänge im wesentlichen in gleicher Höhenlage angeordnet sind.It is beneficial if the facilities for change the tube length and the rod length are essentially the same Altitude are arranged.

Die Längenveränderbarkeit kann in verschiedener Weise vorgenommen werden. Es kann eine Veränderbarkeit in kleinen Stufen vorgesehen sein. Besser ist jedoch eine stufenlose Verstellbarkeit. Dies wird dadurch erreicht, daß das Rohr bzw. ein Rohrstück aus zwei Teilen unterschiedlichen Durchmessers besteht, die teleskopartig ineinandergeschoben sind. Je nach der gewünschen Höhenlage werden die Rohrteile mehr oder weniger weit ineinandergeschoben. Dabei ist es günstig, wenn das obere Rohrteil mit dem kleineren Durchmesser in das untere Rohrteil mit dem größeren Durchmesser eingeschoben ist. Diese Anordnung erleichtert die Unterbringung der Lagerung und Führung der Ventilschraubspindel. Für die Wartung ist der obere Rohrteil auszubauen und die Einrichtung für die Lagerung und Führung der Ventilschraubspindel ist dann gut zugänglich. The length can be changed in different ways become. There can be changeability in small stages be provided. However, an infinitely variable adjustability is better. This is achieved in that the Pipe or a pipe section made of two different parts Diameter exists, which telescoped are. Depending on the desired altitude, the pipe parts more or less pushed together. It is cheap if the upper tube part with the smaller diameter inserted into the lower tube part with the larger diameter is. This arrangement facilitates the placement of the Storage and guidance of the valve screw. For maintenance is to remove the upper pipe section and the device for the Storage and guidance of the valve screw spindle is then good accessible.

Gemäß eines weiteren Aspekts der Erfindung ist es vorgesehen, daß die Sollbruchstelle des Rohres durch die Flanschanordnung gebildet wird und der Ansatz als Sollbruchstelle für das Betätigungsgestänge dient.According to a further aspect of the invention, it is provided that that the predetermined breaking point of the pipe through the flange arrangement is formed and the approach as a predetermined breaking point for the actuating linkage serves.

Das eine Rohrteil trägt vorzugsweise eine Dichtungsanordnung, die am Umfang des anderen Rohrteils abdichtet. Dabei kann die Abdichtung an der Außenfläche des anderen Rohrteils anliegen. Es ist aber auch die Anordnung einer innenliegenden Dichtung möglich.One pipe part preferably carries a sealing arrangement, which seals on the circumference of the other pipe part. The can Apply sealing to the outer surface of the other pipe part. But it is also the arrangement of an internal seal possible.

Zur Veränderung der Gestängelänge schlägt die Erfindung eine Einrichtung vor, die aus einer Mehrkantstange besteht, die mit einer Mutter mit Innenmehrkant zusammenwirkt, wobei das eine dieser Elemente, zum Beispiel die Mehrkantmutter eine Schraubspindel zur Ventilbetätigung antreibt. Durch eine solche Anordnung wird es möglich, ähnlich wie bei der teleskopartigen Veränderbarkeit der Länge des Rohres das Gestänge zusammenzuschieben oder auch auseinanderzuziehen, ohne daß weitere Manipulationen am Hydranten notwendig sind. In jeder Stellung ist eine einwandfreie Ventilbetätigung möglich.The invention proposes to change the rod length Facility that consists of a polygonal rod that with a nut with an internal polygon cooperates, the one of these elements, for example the polygon nut a screw spindle drives for valve actuation. With such an arrangement it becomes possible, similar to the telescopic Changeability of the length of the tube to push the rod together or pull apart without further Manipulations on the hydrant are necessary. In every position proper valve actuation is possible.

Die Erfindung schlägt ferner vor, daß im unteren Rohrteil eine Einrichtung zur Lagerung und Führung der Ventilschraubspindel angeordnet ist und das obere Ende der Ventilschraubspindel mit dem unteren Ende eines Rohres verbunden ist, in das die Mehrkantstange eintaucht und das am oberen Ende die Mehrkantmutter trägt.The invention also proposes that in the lower tube part Device for storing and guiding the valve screw is arranged and the upper end of the valve screw is connected to the lower end of a tube into which the polygonal rod immersed and the polygon nut at the top wearing.

Die Erfindung ist nicht nur bei solchen Hydranten anwendbar, bei denen wesentliche Teile des Hydranten über das Straßenniveau vorstehen. Die Erfindung ist auch bei Unterflurhydranten anwendbar. Dabei ist am oberen Ende des oberen Teiles des Rohres oder Rohrstückes die Ventilstange gelagert und neben der Ventilstangenlagerung ein Kupplungselement für den Anschluß insbesondere eines Schlauches vorgesehen. Das untere Ende des oberen Teiles trägt dabei den einen Teil der Teleskopanordnung.The invention is not only applicable to such hydrants, where essential parts of the hydrant are above street level protrude. The invention is also with underground hydrants applicable. It is at the top of the top of the Pipe or piece of pipe the valve rod stored and next to the Valve rod bearing a coupling element for the connection provided in particular a hose. The lower end of the the upper part carries one part of the telescope arrangement.

Der in den Fig. 1 bis 5 gezeigte Hydrant besteht im wesentlichen aus einem Rohr bzw. mehreren Rohrstücken 16 und 6, wobei das Rohrstück 6 aus den Teilen 7 und 8 aufgebaut ist. Die Rohrstücke 6 und 16 sind durch eine Flanschanordnung 17 miteinander verbunden und der ganze Hydrant ist auf das Ventilgehäuse 18 aufgesetzt und durch eine Flanschanordnung 19 mit dem Ventilgehäuse verbunden. Das Ventilgehäuse 18 besitzt am unteren Ende einen Flansch 20 zur Verbindung des Hydranten mit der jeweiligen Wasserleitung. Im Ventilgehäuse 18 ist eine Ventilkugel 21 beweglich die unter der Wirkung des Wasserdrucks gegen den Ventilsitz 22 gedrückt wird. Bei der Ventilöffnung drückt das Betätigungsorgan 23 die Ventilkugel nach unten, während bei der Schließbewegung die Ventilkugel freigegeben wird. Das Betätigungsorgan wird von dem Rohr 24 bewegt.The hydrant shown in Figs. 1 to 5 consists essentially from a pipe or several pipe sections 16 and 6, wherein the pipe section 6 is made up of parts 7 and 8. The pipe pieces 6 and 16 are connected to one another by a flange arrangement 17 connected and the entire hydrant is on the valve housing 18th placed and through a flange assembly 19 with the valve housing connected. The valve housing 18 has at the lower end a flange 20 for connecting the hydrant to the respective Water pipe. In the valve housing 18 is a valve ball 21 movable under the action of water pressure against the Valve seat 22 is pressed. When you open the valve, it presses Actuator 23, the valve ball down, while at the Closing movement the valve ball is released. The actuator is moved by the tube 24.

Das Ventil kann vom oberen Ende des Hydranten mittels eines geeigneten Schlüssels betätigt werden. Dabei wird die Stange 25 verdreht. Die Stange 25 besitzt am unteren Ende einen mehrkantigen Ansatz 26, der an einen Innenmehrkant 27 eingreift, welcher seinerseits am oberen Ende eine Mehrkant-stange 10 befestigt ist. Es ist klar, daß bei der Drehung der Stange 25 auch die Stange 10 mitgenommen wird. Die Stange 10 umgibt eine Mutter 11, die im oberen Ende des Rohres 15 angeordnet ist und einen Innenmehrkant aufweist, der mit der Mehrkantstange 10 zusammenwirkt. Das Rohr 15 ist mit seinem unteren Ende mit dem oberen Ende der Schraubspindel 12 verbunden damit sich, wie an sich bekannt, über die Spindelmutter 28 das Rohr 24 anheben und absenken läßt, so daß das Ventil geöffnet und geschlossen und geöffnet werden kann.The valve can be opened from the top of the hydrant using a suitable key can be operated. The rod 25 twisted. The rod 25 has a polygonal at the lower end Approach 26, which engages an inner polygon 27, which in turn has a polygonal rod 10 at the upper end is attached. It is clear that when the rod 25 turns, also the rod 10 is taken. The rod 10 surrounds one Nut 11, which is arranged in the upper end of the tube 15 and has an inner polygon, which is connected to the polygonal rod 10 interacts. The tube 15 is at its lower end with the upper end of the screw 12 connected to it, as at known to lift the tube 24 via the spindle nut 28 and can be lowered so that the valve is opened and closed and can be opened.

Das obere Ende des Rohres 24 mit der Spindelmutter 28 und auch die Schraubspindel 12 sind in der Einrichtung 13 gelagert und geführt, die im Rohrteil 8 angeordnet ist.The upper end of the tube 24 with the spindle nut 28 and also the screw 12 are mounted in the device 13 and performed, which is arranged in the tubular part 8.

Der Hydrant soll in der Weise eingebaut werden, daß das Straßenniveau etwa der Linie 29 entspricht. Die Flanschanordnung 17 befindet sich damit knapp oberhalb des Niveaus und bildet die Sollbruchstelle des rohrförmigen Teils, während der Ansatz 26 als Sollbruchstelle für das Betätigungsgestänge dient.The hydrant should be installed in such a way that Street level corresponds approximately to line 29. The flange arrangement 17 is thus just above the level and forms the predetermined breaking point of the tubular part during the Approach 26 as a predetermined breaking point for the actuating linkage serves.

Am oberen Ende des Rohrteiles 8 ist eine Dichtung 9 vorgesehen, die mit dem Außenumfang des Rohrteils 7 zusammenwirkt. Diese Dichtungsanordnung 9 ist fest mit dem Rohrteil 8 verbunden. Die Dichtungsanordnung besteht im wesentlichen aus zwei ringförmigen Dichtungen 30 und 31 sowie einer Lippendichtung 32 zur Abdichtung des Spaltes zwischen den beiden Rohrteilen 7,8.At the upper end of the tube part 8, a seal 9 is provided, which cooperates with the outer circumference of the tubular part 7. This Sealing arrangement 9 is firmly connected to the pipe part 8. The Sealing arrangement consists essentially of two annular Seals 30 and 31 and a lip seal 32 for Sealing the gap between the two pipe parts 7,8.

Um den oberen Teil des Hydranten jeweils in die gewünschte Lage zu bringen, kann der obere teil des Hydranten mit dem Rohrteil 7 und den darüber angeordneten Teilen sowie mit der Mehrkantstange 10 und dem Führungsrohr 33 für das Rohr 15 nach oben gezogen werden oder auch nach unten gedrückt werden. Die Reibung insbesondere zwischen den Rohrteilen 7,8 fixiert den Hydranten in der eingestellten Stellung.Around the upper part of the hydrant in the desired position Bring the top part of the hydrant to the pipe part 7 and the parts arranged above and with the polygonal rod 10 and the guide tube 33 for the tube 15 upwards pulled or pressed down. The Friction in particular between the pipe parts 7,8 fixes the Hydrants in the set position.

In der Fig. 6 ist ein Schnitt durch einen Unterflurhydranten gezeigt. Der untere Teil des Hydranten besitzt die gleiche Ausbildung wie bei den Ausführungsbeispielen nach den Fig. 1 bis 5. Beim Unterflurhydranten nach der Fig. 6 ist am oberen Ende des oberen Teiles 7 des Rohres eine Lagerung 34 vorgesehen für das obere Ende des Gestänges 2. Neben dieser Lagerung 34 ist ein Kupplungselement 35 vorgesehen, an dem zum Beispiel ein Schlauch angeschlossen werden kann.6 is a section through an underground hydrant shown. The lower part of the hydrant has the same design as in the embodiments of FIGS. 1 to 5. The underground hydrant according to FIG. 6 is at the upper end of the upper part 7 of the tube, a bearing 34 is provided for the upper end of the linkage 2. In addition to this storage 34 is a coupling element 35 is provided on which, for example, a Hose can be connected.

Das untere Ende des Teiles 7 wirkt mit der Dichtungsanordnung 9 zusammen, und zwar derart, daß das Rohrstück 7 in das Rohrstück 6 hineingeschoben bzw. herausgezogen werden kann. Das Gestänge 2 ist ebenfalls längenveränderlich ausgebildet.The lower end of part 7 acts with the sealing arrangement 9 together, in such a way that the pipe section 7 in the pipe section 6 can be pushed in or pulled out. The linkage 2 is also variable in length.

Durch die Ausbildung gemäß Fig. 6 wird es möglich, das obere Ende eines Unterflurhydranten nachträglich in seiner Höhenlage zu verändern, um die richtige Höhenlage bezüglich des Straßenniveaus einzustellen.6 makes it possible to use the upper one Subsequent end of an underground hydrant at its altitude to change to the correct altitude with respect to the road level adjust.

Aus der Fig. 7 geht insbesondere hervor wie die Einrichtung 13 im Rohrteil 8 gelagert ist.
