Abstract
Hochdruckverschraubung für die Übertragung von gasförmigen und/oder flüssigen Fluiden, insbesondere zum Betanken von Fahrzeugen, umfassend ein rohrförmiges Gehäuse mit einer zentralen Fluidpassage und darin eingesetzten Klemmringen zur Fixierung von darin eingesteckten Rohren, dadurch gekennzeichnet, dass an dem Gehäuse (1) stirnseitig je eine Schutzhülse (2) mit Endstutzen (2a) angeordnet ist, zwischen denen ein Durchlass (7) zur Durchleitung von Leckagefluid vorgesehen ist.High-pressure for the transmission of gaseous and / or liquid Fluids, in particular for refueling of vehicles, comprising tubular casing with a central fluid passage and clamping rings inserted therein for fixing tubes inserted therein, characterized in that on the housing (1) each end a protective sleeve (2) with end fitting (2a) is arranged, between which a passage (7) is provided for the passage of leakage fluid.
Description
Die Erfindung betrifft eine Hochdruckverschraubung für die Übertragung von gasförmigen und/oder flüssigen Fluiden, mit den oberbegrifflichen Merkmalen des Anspruches 1.The The invention relates to a high pressure fitting for the transmission of gaseous and / or liquid Fluids, with the preamble features of claim 1.
Mit derartigen Hochdruckverschraubungen soll eine sichere Übertragung eines Fluids von einer Druckquelle, beispielsweise von einer Hydraulikpumpe oder Betankungsanlage aus, erreicht werden. Wichtig ist hierbei die leckagefreie Ausführung, um einen Fluidaustritt in die Umgebung zu vermeiden.With Such high-pressure fittings should be a safe transmission a fluid from a pressure source, for example from a hydraulic pump or refueling system. It is important here the leak-free execution, to prevent fluid leakage into the environment.
Eine derartige Hochdruckverschraubung ist beispielsweise in der EP-A-O 753 698 für Druckmittelleitungen oder in der WO 02/01105 für Rohrverschraubungen beschrieben. Derartige Hochdruckverschraubung mit Klemmringen sind Gegenstand der US-Patente 3,584,900 oder 3,103,373, wobei insbesondere die Ausführung der Klemmringe betont wird, um eine sichere Fixierung der angeschlossenen Rohre und deren leckagefreie Abdichtung zu gewährleisten. Bei steigenden Druck von mehr als 400 oder 700 bar werden diese Rohranschlüsse jedoch zunehmend empfindlicher auf Leckagen, so dass im allgemeinen ein Austritt von Fluid, z.B. Hydrauliköl zu erwarten ist. Hierbei könnte es zu Unfällen kommen, insbesondere könnte durch Lecks bei unter Druck stehenden Leitungen erheblicher Schaden entstehen. Zudem können trotz entsprechender Sicherheitsventile erhebliche Fluidmengen austreten.A Such high pressure fitting is for example in EP-A-O 753 698 for Pressure medium lines or described in WO 02/01105 for pipe fittings. Such high-pressure fitting with clamping rings are the subject of US patents 3,584,900 or 3,103,373, wherein in particular the execution of the Clamping rings is emphasized to secure fixation of the connected pipes and to ensure their leak-free sealing. With increasing pressure of more than 400 or 700 bar, however, these pipe connections are increasing more sensitive to leaks, so generally a leakage of fluid, e.g. hydraulic oil is to be expected. This could be it leads to accidents could come, in particular Significant damage from leaks in pressurized pipes arise. In addition, you can despite corresponding safety valves leak considerable amounts of fluid.
Demzufolge liegt der Erfindung die Aufgabe zugrunde, eine Hochdruckverschraubung der eingangs genannten Art bei einfacher Bauweise sicherheitstechnisch zu verbessern, so dass Gefahren bzw. Schäden vermieden werden.As a result, The invention is based on the object, a high-pressure fitting of the type mentioned in a simple design safety improve, so that dangers or damage can be avoided.
Diese Aufgabe wird gelöst durch eine Hochdruckverschraubung gemäss den Merkmalen des Anspruches 1. Bevorzugte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.These Task is solved by a high pressure fitting according to the features of the claim 1. Preferred developments of the invention are the subject of Dependent claims.
Die vorgeschlagene Hochdruckverschraubung zeichnet sich durch eine besonders hohe Sicherheit und einfache Bauweise aus, da durch die vorgeschlagenen Schutzhülsen ein einfacher Anschluss erreicht wird, so dass Gefährdungen bzw. Beschädigungen ausgeschlossen werden können. Insbesondere wird mit der vorgeschlagenen Hochdruckverschraubung sicher vermieden, dass Gas oder Flüssigkeit austreten kann.The proposed high-pressure fitting is characterized by a particularly high security and simple construction, as suggested by the protective sleeves a simple connection is achieved, so that hazards or damage can be excluded. Especially is safely avoided with the proposed high pressure fitting, that gas or liquid can escape.
Dies ist insbesondere aus Unfallschutzgründen wichtig, aber auch zum Umweltschutz, so dass kein erhebliches Fluidvolumen verloren gehen kann.This is particularly important for accident protection reasons, but also for Environmental protection so that no significant fluid volume is lost can.
Es sei darauf hingewiesen, dass sich die vorgeschlagene Hochdruckverschraubung für verschiedene Anschlüsse eignet, insbesondere für Hydraulikanschlüsse im Fahrzeugbau, aber auch bei Industrieanlagen oder zur Kfz-Betankung. Diese Hochdruckverschraubung kann dabei an beliebiger Stelle der Verrohrung in kompakter Weise eingebaut sein und auch Ventile oder Filter innerhalb des Gehäuses der Hochdruckverschraubung in sich aufnehmen.It It should be noted that the proposed high-pressure fitting for different connections is suitable, in particular for hydraulic connections in vehicle construction, but also in industrial plants or for vehicle refueling. This high-pressure fitting can be at any point of the piping be installed in a compact way and also valves or filters within of the housing take the high-pressure fitting in itself.
Nachfolgend wird ein Ausführungsbeispiel anhand der beiliegenden Zeichnungen näher erläutert und beschrieben. Hierin zeigen:following An embodiment is based on the accompanying drawings closer explained and described. Herein show:
