Abstract

The correct spacing of the screw connections (4',4'') and the plane-parallelism of the sealing surfaces of their annular flanges are verified visually by means of lighting units (10). Three simple electric feelers (5-7) are spaced around each bore (2,3) through the checking device (1) which also carries two spirit-levels (11,12). Two cones (17,18) are adjustable on a thread (21) to check the orientation of the connectors (19) w.r.t. the pipes (4), and a rotatable angle (22) checks the distance (L) of the device from the wall. A pressure measuring device (25) may be integrated in the appts. to allow setting of a test pressure. ADVANTAGE - Allows checking of a number of functions using single appts.

Description

Vorrichtungen für die Kontrolle des Abstandes der Anschlußverschrau­ bungen/Stutzen (4′, 4′′) von Haushalts-Gaszähleranschlußarmaturen (z. B. mit DIN-Zweistutzen-Anschluß) sind in vielfältiger Ausführung bekannt und sogar handelsüblich.Devices for checking the distance of the connection screw connections / sockets ( 4 ', 4 '') of household gas meter connection fittings (e.g. with DIN two-socket connection) are known in a variety of designs and are even commercially available.

Die erfindungsgemäße Konstruktion ermöglicht jedoch darüber hinaus die Überprüfung einer Vielzahl von Funktionen mit einem einzigen, mit diesem Gerät. So ist die Überprüfung der Bauteile bezüglich ihrer serienmäßigen Gestaltung, der vorschriftsmäßigen Montage und Axialität der Stutzen (4′, 4′′) einfach möglich.However, the construction according to the invention also enables a multitude of functions to be checked using a single device. So the checking of the components with regard to their standard design, the correct assembly and axiality of the nozzle ( 4 ', 4 '') is easily possible.

Sie erfolgt mittels Kontrolle des richtigen Abstandes der Gaszählerverschraubungen, bzw. der Stutzen (4′, 4′′), und der Planparallelität der Dichtflächen der beiden flächendich­ tenden Ringflanschen dieser Stutzen (4′, 4′′), die zudem optisch über Leuchteinheiten (10) sichtbar gemacht wird. Einfache elektrische Taster (5, 6, 7) sind mit ihren Betätigungselementen um die Auflage der entspr. Dichtflächen der Stutzen (4′, 4′′) herum angebracht, i.B. drei Taster (5, 6, 7) pro Stutzen (i.B. 4′). Diese Taster (5, 6, 7) sollten zweckmäßigerweise noch zusätzlich zu dem eigentlichen Einschalt-Weg (w) auch noch etwas Spiel über den eigentlichen Einschalt-Punkt (p) hinaus haben sollten, woraus sich die zulässige Toleranz (t) ergibt. Diese Taster (5, 6, 7) schließen (je) einen Stromkreis, der die paßgenaue Montage, z. B. mit Leuchteinheiten (10) sichtbar macht. Zusätzlich ist die Dichtheitsprüfung der Anlage, bei der sogar angezeigt wird, auf welcher Seite der Vorrichtung sich die Leckstelle befindet, möglich. Mittels Verschraubung der als Prüfstutzen gedachten Anschlußstutzen (22, 23) mit den Stutzen (4′, 4′′) wird eine druckdichte Verbindung zwischen der, in der Vorrichtung integrierten Verbindungs­ leitung (24), die sich zwischen den beiden Anschlußstutzen (22, 23) befindet, und der restlichen Anlage (Gaszähleranschluß-Einrichtung) hergestellt. Beidseitig der Verbindungsleitung (24) kann nun aus einem Druckmittelbehälter (28) über eine Druckminderer-Absperrein­ richtung (27) und eine Y-förmige Leitung (29) ein Fluid in dieses Leitungssystem strömen. Eine ebenfalls in die Vorrichtung integrierte Druckmeßvorrichtung (25) gestattet die Erhöhung des Druckes bis zum Prüfdruck. In der Mitte, zwischen den beiden Anschlußstutzen (22, 23), ist die Verbindungsleitung (24) transparent. Ein Strömungs­ körper (30) macht die Strömungsrichtung an dieser Stelle sichtbar. Aus der Strömungsrichtung des Fluides ergibt sich die Richtung, in der (Haupt-) Schadensstelle (Leck), von der Vorrichtung aus­ gehend zu suchen ist. Speziell bei umfangreichen Leitungssystemen eine große Erleichterung der Fehlersuche. Zudem erleichtert die Vorrichtung durch die Vorgabe der richtigen Anschlußweite und Höhe die Montage, zumal sie "Libellen" (11, 12) für die räumliche Ausrichtung und Bohrungen (13, 14) als Bohrschablone für die Boh­ rungen (z. B. 15, 16) der Wandhalterung (20) der Gaszähleranschluß- Einrichtung (19) besitzt. Beidseitig bat die Vorrichtung je einen Konus (17, 18), der, einstellbar auf einem Gewinde (21) gehaltert, die Ausrichtung der Einrichtung (19) relativ zu deren Anschluß­ rohren (z. B. 4), oder umgekehrt, erleichtert. Ein drehbarer Winkel (22) sorgt für die Überprüfbarkeit der Einhaltung des richtigen Wandabstandes (L) der Einrichtung.It is carried out by checking the correct distance between the gas meter screw connections, or the connecting pieces ( 4 ', 4 ''), and the plane-parallelism of the sealing surfaces of the two surface-sealing ring flanges of these connecting pieces ( 4 ', 4 ''), which are also optically controlled by light units ( 10 ) is made visible. Simple electrical buttons ( 5 , 6 , 7 ) are attached with their actuating elements around the support of the corresponding sealing surfaces of the connecting piece ( 4 ′, 4 ′ ′), generally three buttons ( 5 , 6 , 7 ) per connecting piece (iB 4 ′ ). These push buttons ( 5 , 6 , 7 ) should expediently have some play beyond the actual switch-on point (p) in addition to the actual switch-on path (w), which results in the permissible tolerance (t). These buttons ( 5 , 6 , 7 ) close (each) a circuit, which is the perfect fit, z. B. with lighting units ( 10 ). In addition, the leak test of the system, which even shows which side of the device the leak is located on, is possible. By screwing the connection piece ( 22 , 23 ) intended as a test piece with the piece ( 4 ', 4 '') is a pressure-tight connection between the integrated in the device connecting line ( 24 ), which is between the two connecting pieces ( 22 , 23rd ), and the rest of the system (gas meter connection device). Both sides of the connecting line ( 24 ) can now flow from a pressure medium container ( 28 ) via a pressure reducer shut-off device ( 27 ) and a Y-shaped line ( 29 ) into this line system. A pressure measuring device ( 25 ) also integrated in the device allows the pressure to be increased up to the test pressure. In the middle, between the two connecting pieces ( 22 , 23 ), the connecting line ( 24 ) is transparent. A flow body ( 30 ) makes the flow direction visible at this point. From the direction of flow of the fluid, the direction in which the (main) damage point (leak) is to be sought, starting from the device, results. This makes troubleshooting much easier, especially with extensive piping systems. In addition, the device facilitates the installation by specifying the correct connection width and height, especially since it "dragonflies" ( 11 , 12 ) for spatial alignment and holes ( 13 , 14 ) as drilling template for the bores (z. B. 15, 16th ) the wall bracket ( 20 ) of the gas meter connection device ( 19 ). On both sides the device asked for a cone ( 17 , 18 ) which, adjustable on a thread ( 21 ), made it easier to align the device ( 19 ) relative to its connection (e.g. 4 ), or vice versa. A rotatable angle ( 22 ) ensures that the correct distance from the wall (L) of the device can be checked.
