Definitions
- the invention relates to a device for determining the pressure difference between two spaced locations of a hot water heating system, namely between the inlet and the outlet of a radiator, each with a connection for a pressure gauge.
- a comparable apparatus showing the features of the preamble of claim 1 is known from DE 102 11 533 known and designed as a tap block, wherein the inlet and the outlet of a radiator are connected to a common valve.
- the tap block according to the DE 102 11 533 B4 is connectable to adjacent pipes, one of which form the flow and the other the drain of the heating water of a radiator.
- This tap block has two respective lines associated connection points for pressure gauges, which are designed as pierceable membranes, so that the meter must be designed in a customized form.
- the device comprises two separate or separate pipe fittings, which are used in the course of pipes of the heating system immediately at the entrance to the radiator that the pipe connections are connected to the radiator and that each of these pipe fittings a branch with a self-sealing Quick coupling for a pressure gauge connection has.
- the device has separate or separate pipe fittings that are used or fit in the course of pipelines of heating systems, and that each of these pipe fittings has a branch with a self-sealing self-coupling for a pressure gauge device connection.
- each of the two pipe connecting pieces has two spaced, coaxial threaded connections which fit counter threads in the pipes and / or on a radiator. This makes a very simple installation of the pipe fittings possible by their screwing to the pipes or radiators.
- the respective pipe connection piece is divided between its threads and the two sections are rotatable and sealed relative to each other attached to each other. This makes it possible to turn the branch for a pressure gauge connection after assembly in any direction relative to the pipe and the pipe fitting and bring them into a favorable position. If two rotatable relative to each other parts form the pipe fitting, for example, one of the two threads fixed, then rotates the relatively rotatable part with the pressure gauge connection in the desired position and then the attachment to the second port with a union nut are performed.
- the meter port could be located on the pipe fitting in any direction transverse to the central axis of the pipe fitting. But it is particularly favorable when this measuring device connection is arranged on the pipe connection piece radially to the flow direction of the heating medium and to the Länksstoffachse of the pipe connection piece.
- the measuring device connection can be easily reached in each case with different arrangements of the pipe connection piece. Said arrangement gives the best possible accessibility of the pressure gauge connection from all sides.
- a spring-loaded closure element can cooperate with a seal or sealing point, and this closure element can be movable with the pressure measuring device connection from its sealing point or its sealing seat into the open position. It can thereby be achieved that, when the pressure gauge is connected to the meter connection, the pressure in the piping system immediately becomes active on this pressure gauge, without the need for additional, possibly even possible, closure elements to be opened separately. If the pressure gauge is released from the meter connection, this is also automatically closed again in an advantageous manner. This results in a particularly simple handling.
- a device designated as a whole by 1 serves to determine the pressure difference between two spaced locations 2 and 3 of a hot water heating system, in the illustrated embodiments between the inlet and the outlet of a radiator 4 and each has a port 5 for a pressure gauge 6, which with the terminals 5 according to FIG. 1 and 4 can be connected via hoses or flexible cables 7.
- the device 1 has two separate, ie separate, generally designated 8 pipe fittings, in the course of pipes of the heating system, in the embodiment directly at the entrance to the radiator 4, are used.
- Each of these pipe fittings 8 has a branch 9 with an internally arranged self-sealing quick coupling as a connection 5 for a pressure gauge connection, as shown in the FIGS. 1 and 4 is shown.
- Each of the two pipe connecting pieces 8 of the device 1 has two axially spaced, coaxial threaded connections 10 and 10 a, which fit into counter-threads in the pipes not shown in detail and / or on the radiator 4. In all figures, the connection of the pipe connections 8 by means of threads on the radiator 4 is shown.
- the threaded connection 10 for connecting to the radiator 4 has an external thread that fits into a corresponding counter-threaded connector, while in the embodiments according to FIGS. 4 to 6 4 external thread are arranged on these neck of the radiator, which fit with a union connected to the pipe connections 8 union nut and are connectable to this.
- not only differently shaped threads namely on the one hand an external thread and on the other hand a union nut or an internal thread
- differently sized threads for adaptation to the mating thread of the respective pipe and / or the radiator 4 may be provided at the inlet and the outlet of the respective pipe fitting 8 in order to be able to connect the pressure gauge 6 at a suitable point of the heating system.
- the measuring device connection 5 is arranged on the pipe connecting piece 8 radially to the direction of passage of the heating medium.
- the free end of the connection 5 is correspondingly well accessible to the measuring device line 7.
- the multi-part device 1 which can also be referred to or regarded as a kit serves to determine the pressure difference between two spaced locations 2 and 3 of a Hot water heating system, preferably between the inlet and the outlet of a radiator 4 directly to corresponding, belonging to the radiator 4 connecting piece, and each has a connection 5 for a pressure gauge 6, which can be connected by means of a line 7 and a clutch 12. It is essential in the device 1, that two separate or separate, ie independently mountable pipe fittings 8 are provided, which are connectable to the course of pipes or to the points 2 and 3 of a radiator 4 and each have a branch 9 with a self-sealing quick coupling Have port 5 for the pressure gauge 6.

Description
Die Erfindung betrifft eine Vorrichtung zur Ermittlung der Druckdifferenz zwischen zwei beabstandeten Stellen eine Warmwasser-Heizanlage, nämlich zwischen dem Zulauf und dem Ablauf eines Heizkörpers, jeweils mit einem Anschluss für ein Druckmessgerät.The invention relates to a device for determining the pressure difference between two spaced locations of a hot water heating system, namely between the inlet and the outlet of a radiator, each with a connection for a pressure gauge.
Eine vergleichbare Vorrichtung, die die Merkmale des Oberbegriffs von Anspruch 1 zeigt, ist aus der
Nicht selten erlauben jedoch die Platzverhältnisse an Heizkörpern keine Anwendung eines Hahnblocks und außerdem macht es ein Hahnblock erforderlich, dass die beiden Rohrleitungen in einem ganz bestimmten, genau festliegenden Abstand zueinander angeordnet sein müssen.Not infrequently, however, the space available on radiators does not allow the use of a faucet block and, moreover, a faucet block requires that the two pipelines be in a particular, must be arranged exactly fixed distance to each other.
Aus der
Es besteht die Aufgabe, eine Vorrichtung der eingangs definierten Art zu schaffen, die praktisch unabhängig von dem Verlauf der jeweiligen Rohre und Leitungen und Heizkörperanschlüssen ist und bei welcher durchstechbare Membranen für den Anschluss des Druckmessgeräts vermieden werden könne.It is the object to provide a device of the type defined, which is practically independent of the course of the respective pipes and lines and radiator connections and in which pierceable membranes for the connection of the pressure gauge could be avoided.
Diese Aufgabe wird mit den Merkmalen und Mitteln des Patentanspruchs 1 gelöst. Demgemäß ist vorgesehen, dass die Vorrichtung zwei getrennte oder separate Rohranschlussstücke aufweist, die in den Verlauf von Rohrleitungen der Heizanlage unmittelbar an deren Eintritt in den Heizkörper einsetzbar sind, dass die Rohranschlüsse mit dem Heizkörper verbunden sind und dass jedes dieser Rohranschlussstücke eine Abzweigung mit einer selbstdichtenden Schnellkupplung für einen Druckmessgeräteanschluss aufweist.This object is achieved with the features and means of
Zur Lösung dieser Aufgabe ist vorgesehen, dass die Vorrichtung getrennte oder separate Rohranschlussstücke aufweist, die in den Verlauf von Rohrleitungen von Heizanlagen einsetzbar sind oder passen, und das jedes dieser Rohranschlussstücke eine Abzweigung mit einer selbst dichtenden Selbstkupplung für einen Druckmessegeräteanschluss aufweist.To achieve this object, it is provided that the device has separate or separate pipe fittings that are used or fit in the course of pipelines of heating systems, and that each of these pipe fittings has a branch with a self-sealing self-coupling for a pressure gauge device connection.
Dadurch ist es möglich, Differenzdrücke auch an beabstandeten Stellen von zu Heizanlagen gehörenden und/oder Heizkörpern führenden Rohrleitungen, sei es innerhalb eines Rohrsystems, sei es vor allem am Zulauf und am Ablauf eines Heizkörpers, zu messen. Es genügt, an den gewünschten Messstellen die zu der Vorrichtung gehörenden oder sie bildenden Rohranschlussstücke zu installieren und dann das entsprechende Messgerät anzuschließen. Da dazu selbstdichtende Schnellkupplungen zur Verfügung stehen, sind keine durchstechbaren Membranen erforderlich, die durch derartige Messvorgänge beschädigt werden könnten.This makes it possible differential pressures also at spaced locations belonging to heating systems and / or radiators leading pipelines, be it within a piping system, be it primarily at the inlet and at the outlet of a radiator to measure. It is sufficient to install at the desired measuring points belonging to the device or forming pipe fittings and then connect the appropriate meter. Since self-sealing quick couplings are available, no pierceable membranes are required, which could be damaged by such measuring operations.
Zweckmäßig ist es, wenn jedes der beiden Rohranschlussstücke zwei beabstandete, koaxiale Gewindeanschlüsse aufweist, die zu Gegengewinden in den Rohrleitungen und/oder an einem Heizkörper passen. Dadurch ist eine sehr einfache Montage der Rohranschlussstücke durch ihre Verschraubung mit den Rohrleitungen oder Heizkörpern möglich.It is expedient if each of the two pipe connecting pieces has two spaced, coaxial threaded connections which fit counter threads in the pipes and / or on a radiator. This makes a very simple installation of the pipe fittings possible by their screwing to the pipes or radiators.
Zweckmäßig kann es dabei sein, dass beim Eintritt und am Austritt des jeweiligen Rohranschlussstücks unterschiedlich bemessene oder geformte Gewinde zur Anpassung an die Gegengewinde der jeweiligen Rohrleitung und/oder des Heizkörpers vorgesehen sind. Somit ist es möglich, dass unterschiedliche Gewinde am Eintritt und am Austritt des jeweiligen Rohrstücks oder Rohrleitungsstücks vorgesehen sind, so dass beispielsweise die Rohranschlussstücke auch an Heizkörper mit Zollgewinde angeschlossen und dann mit einer Rohleitung mit metrischem Gewinde verbunden werden können oder umgekehrt. Auch differierende Abmessungen der jeweiligen Gewinde können auf diese Weise berücksichtigt werden.Appropriately, it may be the case that differently sized or shaped threads are provided for adaptation to the mating threads of the respective pipe and / or the radiator at the inlet and at the outlet of the respective pipe connection piece. Thus, it is possible that different threads are provided at the inlet and at the outlet of the respective pipe piece or pipe piece, so that for example the pipe fittings can also be connected to radiators with an inch thread and then connected to a pipe with metric thread or vice versa. Even different dimensions of the respective thread can be taken into account in this way.
Besonders günstig ist es dabei, wenn das jeweilige Rohranschlussstück zwischen seinen Gewinden unterteilt ist und die beiden Teilstücke relativ zueinander drehbar und abgedichtet aneinander befestigt sind. Dies erlaubt es, die Abzweigung für einen Durckmessgeräteanschluss nach der Montage in eine beliebige Richtung relativ zu der Rohrleitung und dem Rohranschlussstück zu verdrehen und in eine günstige Position zu bringen. Wenn dabei zwei relativ zueinander verdrehbare Teile das Rohranschlussstück bilden, kann beispielsweise eines der beiden Gewinde fixiert, dann das relativ dazu drehbare Teil mit dem Druckmessgeräteanschluss in die gewünschte Position verdreht und danach die Befestigung an dem zweiten Anschluss mit einer Überwurfmutter durchgeführt werden.It is particularly advantageous if the respective pipe connection piece is divided between its threads and the two sections are rotatable and sealed relative to each other attached to each other. This makes it possible to turn the branch for a pressure gauge connection after assembly in any direction relative to the pipe and the pipe fitting and bring them into a favorable position. If two rotatable relative to each other parts form the pipe fitting, for example, one of the two threads fixed, then rotates the relatively rotatable part with the pressure gauge connection in the desired position and then the attachment to the second port with a union nut are performed.
Der Messgeräteanschluss könnte an dem Rohranschlussstück in einer beliebigen Richtung quer zur Mittelachse des Rohranschlussstückes angeordnet sein. Besonders günstig es aber, wenn dieser Messgeräteanschluss an dem Rohranschlussstück radial zu der Durchflussrichtung des Heizmediums und zu der Länksmittelachse des Rohranschlussstücks angeordnet ist.The meter port could be located on the pipe fitting in any direction transverse to the central axis of the pipe fitting. But it is particularly favorable when this measuring device connection is arranged on the pipe connection piece radially to the flow direction of the heating medium and to the Länksmittelachse of the pipe connection piece.
Dadurch ist bei unterschiedlichen Anordnungen des Rohranschlussstücks der Messgeräteanschluss jeweils gut erreichbar. Die genannte Anordnung ergibt eine möglichst gute Zugänglichkeit des Druckmessgeräteanschlusses von allen Seiten her.As a result, the measuring device connection can be easily reached in each case with different arrangements of the pipe connection piece. Said arrangement gives the best possible accessibility of the pressure gauge connection from all sides.
Im Inneren des Messgeräteanschlusses kann ein federbelastetes Verschlusselement mit einer Dichtung oder Dichtstelle zusammen wirken und dieses Verschlusselement kann mit dem Druckmessgeräteanschluss von seiner Dichtungsstelle oder seinem Dichtsitz in Öffnungsstellung bewegbar sein. Dadurch kann erreicht werden, dass beim Anschließen des Druckmessgerätes an den Messgeräteanschluss auch gleich der in dem Rohrleitungssystem befindliche Druck auf dieses Druckmessgerät wirksam wird, ohne dass zusätzliche, gegebenenfalls auch noch mögliche Verschlusselemente separat geöffnet werden müssen. Wird das Druckmessgerät von dem Messgeräteanschluss gelöst, ist dieser auch in vorteilhafter Weise wieder automatisch verschlossen. Somit ergibt sich eine besonders einfache Handhabung.Inside the meter connection, a spring-loaded closure element can cooperate with a seal or sealing point, and this closure element can be movable with the pressure measuring device connection from its sealing point or its sealing seat into the open position. It can thereby be achieved that, when the pressure gauge is connected to the meter connection, the pressure in the piping system immediately becomes active on this pressure gauge, without the need for additional, possibly even possible, closure elements to be opened separately. If the pressure gauge is released from the meter connection, this is also automatically closed again in an advantageous manner. This results in a particularly simple handling.
