Description
Die Erfindung bezieht sich auf Rohrleitungen für ein unter wechselndem Druck stehendes flüssiges oder gasförmiges Medium, insbesondere bei beweglichen Schnellkupplungsrohrleitungen und Schlauchleitungen in der Beregnungs- und Feuerlöschtechnik. Durch Betriebspausen und Störungen treten sogenannte Wasserschläge auf, die oft ein Vierfaches des normalen Betriebsdruckes betragen und wertvolles Schlauchmaterial und dünnwandige Schnellkupplungsrohre zum Platzen bringen. Die Aufgabe, ein einkuppelbares Sicherheitsventil im Leitungssystem anzubringen, wird durch die vorliegende Erfindung in vorteilhafter Weise gelöst.The invention relates to pipelines for an under changing Pressurized liquid or gaseous medium, especially in the case of moving ones Quick coupling pipelines and hose lines in irrigation and fire extinguishing technology. Due to breaks in operation and malfunctions, so-called water hammer occurs, which is often four times the normal operating pressure and valuable hose material and bursting thin-walled quick coupling pipes. The task of a disengageable Attaching a safety valve in the line system is made possible by the present invention solved in an advantageous manner.
Die Erfindung besteht darin, daß der Kupplungsabzweig eines in die Leitung eingekuppelten T -Stücks eine leicht ankuppelbare Verschlußkappe besitzt, die als Sicherheitsventil ausgebildet ist. Die Leitung ist dadurch geschützt, außerdem kann das Sicherheitsventil je nach Bedarf an Stelle von normalen, ankuppelbaren Verschlußkappen treten. Da die Verschlußkappe mit dem Ventil eine organische Einheit mit der Kupplung bildet, kann diese ebensogut auch am Ende einer Rohrleitung eingekuppelt werden.The invention consists in that the coupling branch one into the The line of the coupled T-piece has an easy-to-connect cap, which is designed as a safety valve. The line is protected by it, as well the safety valve can be used instead of normal, attachable ones as required Stepping on the caps. Because the cap and the valve form an organic unit forms with the coupling, this can just as well be coupled at the end of a pipeline will.
In der Zeichnung ist mit den Abb. i bis 4 der Gegenstand der Erfindung zum Teil im Schnitt, in Ansicht und Draufsicht dargestellt. Es bezeichnet a den Kupplungsabzweig eines T-Stückes mit Kupplungsmutterteil, in dem ein Kupplungsvaterteil b mit rohrförmigem Aufsatzstück eingekuppelt ist. Hierin ist der Ventilsitz c, cl abgestützt. Das Widerlager für die Schließfeder besteht aus einem Bügel g, der mit einem Klemmring g1, der mit dem rohrförmigen Aufsatzstück verbunden ist, gleichzeitig die Verschlußteile a1, a, für die Kupplung trägt und eine Stellschraube h. Hiermit kann der Abstand der beiden f Widerlager f und f1 verändert werden, was einer mehr oder weniger großen Vorspannung der Ventilfeder und damit einer Einstellung für einen bestimmten Abströmungsdruck gleich kommt.In the drawing, Figs. I to 4, the subject of the invention partly shown in section, in elevation and plan view. It denotes a den Coupling branch of a T-piece with coupling nut part, in which a coupling father part b is coupled with a tubular attachment piece. Here the valve seat is c, cl supported. The abutment for the closing spring consists of a bracket g, which is with a clamping ring g1, which is connected to the tubular attachment piece, at the same time the locking parts a1, a, carries for the coupling and an adjusting screw h. Herewith the distance between the two f abutments f and f1 can be changed, which is one more or less large bias of the valve spring and thus an adjustment for equals a certain discharge pressure.
Durch die Erfindung können die durch Wasser-oder Luftschläge in Schlauch- und Rohrleitungen verursachten Unglücksfälle zuverlässig und einfach vermieden werden.With the invention, the water or air hammer in hose and pipelines caused accidents can be reliably and easily avoided.
