Abstract

The disconnector has upstream and downstream backflow preventers (30,44) combined with a relief valve (18) to form a structural unit. The relief valve has a slide valve with an upstream end face exposed to water pressure from inlet port unit. A downstream end face is exposed to pressure in space between the preventers. The slide valve covers a lateral outlet opening/drain passage of disconnector casing, in its closed position. The slide valve body is moving in a flow passage between open and closed positions under the action of a pressure difference between the inlet and a space. The body covers a drain passage in its closed position.

Description

Die Erfindung betrifft eine Ventilanordnung für einen Rohrtrenner zum Trennen eines aus einem Trinkwassersystem auf- oder nachfüllbaren Brauchwassersystem von diesem Trinkwassersystem, mit einem stromaufwärtigen und einem stromabwärtigen Rückflußverhinderer, die beide in Richtung von dem Brauchwassersystem zu dem Trinkwassersystem schließen, und einem Entlastungsventil, das von dem Druck des Trinkwassersystems in Schließrichtung beaufschlagt ist und über das der Raum zwischen den Rückflußverhinderern bei Wegfall dieses Druckes mit einem Ablauf verbindbar ist.The invention relates to a valve arrangement for a pipe separator for separating a from a drinking water system refillable or refillable domestic water system from this Drinking water system, with one upstream and one downstream Backflow preventer, both in the direction from the domestic water system to the Close the drinking water system, and a relief valve that depends on the pressure of the Drinking water system is acted upon in the closing direction and through which the space between the backflow preventer can be connected to a drain when this pressure is removed.

Das Brauchwassersystem kann beispielsweise ein Heizungssystem sein. Ein solches Heizungssystem wird aus einem Trinkwassersystem, der Trinkwasserleitung, gefüllt oder nachgefüllt. Es muß unter allen Umständen verhindert werden, daß etwa bei einem Druckabfall im Trinkwassersystem Wasser aus dem Brauchwassersystem in das Trinkwassersystem zurückfließt. Zu diesem Zweck sind "Rückflußverhinderer" vorgesehen. Das sind federbelastete Rückschlagventile, die unter dem Einfluß des Trinkwasserdrucks nur in Richtung vom Trinkwassersystem zum Brauchwassersystem hin öffnen. Für den Dauerbetrieb wird jedoch auch dies nicht als ausreichend angesehen. Vielmehr ist nach Abschluß des Füll- oder Nachfüllvorganges eine physische Trennung zwischen Trinkwassersystem und Brauchwassersystem vorgeschrieben, beispielsweise durch Füllen oder Nachfüllen über einen Schlauch, der nach Abschluß des Füll- oder Nachfüllvorganges entfernt wird. Dadurch wird sichergestellt, daß auch über undichte Absperrventile oder Rückflußverhinderer kein Brauchwasser in das Trinkwassersystem gelangen kann. The domestic water system can be a heating system, for example. Such one Heating system is filled from a drinking water system, the drinking water pipe, or refilled. It must be prevented under all circumstances that one Pressure drop in the drinking water system Water from the domestic water system into the Drinking water system flows back. For this purpose, "non-return valves" intended. These are spring-loaded check valves that are under the influence of the Drinking water pressure only in the direction from the drinking water system to the domestic water system open up. However, this is also not considered sufficient for continuous operation. Rather, after the filling or refilling process is complete, there is a physical separation between drinking water system and process water system, for example by filling or refilling via a hose which after the completion of the filling or Refilling process is removed. This ensures that even leaks Shut-off valves or backflow preventer no hot water in the drinking water system can reach.

Da das Entfernen des Schlauchs nach dem Füll- oder Nachfüllvorgang lästig ist und auch nicht kontrolliert werden kann sind feste Installationen von "Rohrtrennern" bekannt (beispielsweise EP 0 972 995 A1). Diese bekannten Rohrtrenner enthalten einen stromaufwärtigen, d.h. auf der Seite des Trinkwassersystems angeordneten, und einen stromabwärtigen, d.h. auf der Seite des Brauchwassersystems angeordneten Rückflußverhinderer. Beide Rückflußverhinderer öffnen in Richtung auf das Brauchwassersystem hin. Zwischen den Rückflußverhinderern ist ein druckgesteuertes Entlastungsventil angeordnet. Dieses Entlastungsventil ist von dem Trinkwasserdruck gesteuert und öffnet automatisch, wenn der Trinkwasserdruck wegfällt oder absinkt. Wenn somit das Brauchwassersystem aus dem Trinkwassersystem gefüllt oder nachgefüllt wird und ein dafür ausreichender Trinkwasserdruck vorhanden ist, dann wird das Entlastungsventil von diesem Druck geschlossen. Es fließt Trinkwasser über die von dem Trinkwasserdruck aufgedrückten Rückflußverhinderer in das Brauchwassersystem. Wenn aber der Trinkwasserdruck unter ein vorgegebenes Maß absinkt, sei es weil ein Absperrventil das Trinkwassersystem absperrt, sei es weil der Trinkwasserdruck aus irgendeinem Grund zusammenbricht, öffnet das Entlastungsventil. Selbst wenn dann über einen lecken Rückflußverhinderer Brauchwasser aus dem Brauchwassersystem zurückfließt, fließt dieses zurückfließende Brauchwasser über den Ablaufab und kann auf keinen Fall in das Trinkwassersystem gelangen.Because the removal of the hose after the filling or refilling process is annoying and also Fixed installations of "pipe separators" cannot be checked (for example EP 0 972 995 A1). These known pipe separators contain one upstream, i.e. arranged on the side of the drinking water system, and one downstream, i.e. arranged on the side of the domestic water system Backflow preventer. Both check valves open towards that Domestic water system. There is a pressure-controlled one between the non-return valves Relief valve arranged. This relief valve is from the drinking water pressure controlled and opens automatically when the drinking water pressure drops or drops. So when the domestic water system is filled from the drinking water system or is refilled and there is sufficient drinking water pressure, then the relief valve closed from this pressure. Drinking water flows over the of the backflow preventer pressed into the drinking water system. But if the drinking water pressure drops below a predetermined level, be it because of a Shut-off valve shuts off the drinking water system, be it because the drinking water pressure is off breaks down for any reason, the relief valve opens. Even if then a leaked backflow preventer service water from the service water system flows back, this backflowing used water flows over the drain and can open never get into the drinking water system.

Durch die Firmendruckschrift "SYR Füllgruppe Typ 2128" der Hans Sasserath & Co. KG ist eine Füllgruppe bekannt, die an dem Brauchwassersystem, z.B. einer geschlossenen Heizungsanlage, fest installiert ist und einen Anschluß für einen Schlauch aufweist. Über den so anzuschließenden Schlauch wird die Füllgruppe mit einem Trinkwassersystem verbunden. Die Füllgruppe enthält ein Absperrventil und einen Druckminderer.By the company publication "SYR Füllgruppe Typ 2128" from Hans Sasserath & Co. KG a filling group is known which is connected to the domestic water system, e.g. one closed Heating system, is permanently installed and has a connection for a hose. about the hose to be connected in this way becomes the filling group with a drinking water system connected. The filling group contains a shut-off valve and a pressure reducer.

Der Erfindung liegt die Aufgabe zugrunde, den Füllvorgang mit einer Rohrtrenneranordnung der eingangs genannten Art zu vereinfachen und zu erleichtern.The invention has for its object the filling process with a To simplify and facilitate pipe separator arrangement of the type mentioned.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß ein mit einem Einlaßanschluß und einem Auslaßanschluß fest zwischen ein Trinkwassersystem und ein Brauchwassersystem installierbares, die Rückflußverhinderer und das Entlastungsventil enthaltendes Rohrtrennergehäuse stromauf von dem stromaufwärtigen Rückflußverhinderer im Strömungsweg integriert ein Absperrventil und einen Druckminderer aufweist.According to the invention, this object is achieved in that one with an inlet connection and an outlet connection between a drinking water system and a Service water system installable, the backflow preventer and the relief valve containing pipe separator housing upstream of the upstream Backflow preventer in the flow path integrates a shut-off valve and one Has pressure reducer.

Eine solche Rohrtrenneranordnung ist fest zwischen Trinkwassersystem und Brauchwassersystem, z.B. eine Warmwasser-Zentralheizungsanlage, installiert. Zum Füllen oder Nachfüllen braucht keine Schlauchverbindung hergestellt zu werden. Das erleichtert die Handhabung. Durch das automatische Öffnen des Entlastungsventils bei Wegfall einer Druckdifferenz zwischen Trinkwassersystem und Brauchwassersystem ist in diesem Fall eine mechanische Trennung der Systeme gewährleistet. Durch einen eingebauten Druckminderer wird sichergestellt, daß der Druck im Brauchwassersystem einen vorgegebenen Wert nicht überschreiten kann. Wenn der Druck im Brauchwassersystem den am Druckminderer eingestellten Druck erreicht, schließt das Ventil des Druckminderers und unterbricht damit den Füllvorgang, auch wenn der Druck im Trinkwassersystem höher sein sollte. Der Druckminderer bietet eine zusätzliche Sicherheit gegen einen Rückfluß von Brauchwasser in das Trinkwassersystem. Durch das Absperrventil kann der Füllvorgang unterbrochen und das Trinkwassersystem im Normalbetrieb sicher von dem Brauchwassersystem getrennt werden, unabhängig z.B. von den Rückflußverhinderern. Die ganze Rohrtrenneranordnung ist eine kompakte und leicht zu installierende Baugruppe.Such a pipe separator arrangement is fixed between the drinking water system and Domestic water system, e.g. a hot water central heating system installed. To the No hose connection needs to be made to fill or refill. The makes handling easier. By automatically opening the relief valve at There is no pressure difference between the drinking water system and the domestic water system in this case a mechanical separation of the systems is guaranteed. Through a built-in pressure reducer ensures that the pressure in the domestic water system cannot exceed a predetermined value. If the pressure in the The domestic water system reaches the pressure set on the pressure reducer, this closes Valve of the pressure reducer and thus interrupts the filling process, even if the pressure should be higher in the drinking water system. The pressure reducer offers an additional one Security against the backflow of process water into the drinking water system. By the Shut-off valve can interrupt the filling process and the drinking water system in the Normal operation can be safely separated from the hot water system, independently e.g. from the backflow preventer. The whole pipe separator arrangement is compact and easy to install assembly.
