Beschreibungdescription
Gasdruckregelgerät mit zwei membrangesteuerten Ventileinrichtungen Die Erfindung betrifft ein Gasdruckregelgerät mit zwei membrangesteuerten Ventileinrichtungen, deren Regelmembranen am gemeinsamen Gehäuse befestigt diametral gegenüberliegen, vorgesehen insbesondere zum Einbau in Fahrzeuge.Gas pressure regulator with two diaphragm-controlled valve devices The invention relates to a gas pressure regulator with two membrane-controlled valve devices, whose regulating diaphragms are attached to the common housing and are diametrically opposed, intended especially for installation in vehicles.
Bei bestimmten Gasversorgungsanlagen in Fahrzeugen, die aus nur einer Flüssiggasflasche gespeist werden, wird der Flaschendruck in diesem Druckregelgerät in der ersten Regelstufe auf etwa 1,5 bar vorgeregelt, während die zweite Ventileinrichtung,auf einen Druck von ca. 1,75 bar eingestellt, eine Sicherheitsregelstufe darstellt, die erst in Funktion tritt, wenn die erste Regelstufe versagt. In einem weiteren nachgeschalteten Druckregelgerät wird dieser vorgeregelte Druck dann auf den Gebrauchsdruck für die Gasgeräte entspannt. Dieses Gasdruckregelgerät mit zwei Ventileinrichtungen wird an der Fahrzeugwand befestigt, eingangsseitig durch eine Schlauchleitung mit der Flüssiggasflasche und ausgangsseitig durch eine weiterführende Rohrleitung mit dem zweiten Druckregelgerät verbunden.With certain gas supply systems in vehicles that consist of only one LPG cylinder are fed, the cylinder pressure in this pressure regulator pre-regulated to around 1.5 bar in the first control stage, while the second valve device opens a pressure of approx. 1.75 bar is set, represents a safety control stage, which only comes into operation when the first control stage fails. In another downstream pressure regulator, this pre-regulated pressure is then adjusted to the working pressure relaxed for the gas appliances. This gas pressure regulator with two valve devices is attached to the vehicle wall, with a hose on the inlet side the liquefied gas cylinder and on the outlet side through a further pipeline connected to the second pressure regulator.
Durch die DE-PS 19 20 430 ist eine Druckminder- und Umschaltvorrichtung mit einem Druckbegrenzer, untergebracht in einer kleineren Druckkapsel gegenüber der Druckregelmembran, bekannt, die sich für den Anschluß von zwei Flüssiggasflaschen eignet. Für den Anschluß nur einer Flüssiggasflasche muß dabei eine Anschluß seite blind verschlossen werden.Die vorhandene Umschalteinrichtung wird dann nicht benötigt.DE-PS 19 20 430 is a pressure reducing and switching device with a pressure limiter, housed in a smaller pressure capsule opposite the pressure regulating diaphragm, known for the connection of two liquid gas bottles suitable. For the connection of only one liquefied gas bottle, one connection side must be required The existing switching device is then not required.
Nachteilig ist weiter, daß der Ausgangsanschluß immer nur zwischen den beiden Eingangsanschlüssen liegt, obwohl bei manchen Fahrzeugen ein Gasabgang gegenüber dem Gaseingang gewünscht wird. Eine fehlende Befestigungseinrichtung erschwert weiter die Befestigung dieses Druckregelgerätes an der Fahrzeugwand. Von der Sicherheitsfunktion her gesehen ist es nachteilig, daß die Membran der Druckbegrenzungseinrichtung einen kleineren Durchmesser aufweist als die Druckmindermembran der ersten Regelstufe.Another disadvantage is that the output connection is always only between the two inlet connections, although some vehicles have a gas outlet opposite the gas inlet is desired. A missing fastening device makes it difficult further the attachment of this pressure regulator to the vehicle wall. From the safety function Seen here it is disadvantageous that the membrane of the pressure limiting device one Has a smaller diameter than the pressure reducing diaphragm of the first control stage.
Der Erfindung liegt die Ãufgâbe zugrunde, ein den praktischen Anforderungen gerecht werdendes Gasdruckregelgerät zu gestalten, welches die unterschiedlichen Befestigungsmöglichkeiten im Flaschenkasten des Fahrzeuges und die damit auch verbundene unterschiedliche Leitungsführung für den Gaseingangs- und Gasausgangsanschluß ermöglicht. Eine weitere Forderung ist, das aus Metall bestehende Gasdruckreglergehäuse wegen der Fahrzeugerschütterungen in seiner Masse möglichst leicht zu halten, andererseits aber eine sehr stabile Befestigung zwischen der Gehäusewandung und den Anschlußstutzen zu schaffen, damit die Erschütterungen während des Fahrens zu keinem Bruch an der dünnen Gehäusewandung führen. An das mit zwei membrangesteuerten Ventileinrichtungen ausgerüstete Gasdruckregelgerät wird weiterhin die Aufgabe gestellt, daß beim Versagen der ersten Regelstufe die nachgeschaltete zweite Ventileinrichtung die Sicherheitsregelfunktion mit der bestmöglichen Regelgenauigkeit übernimmt.The invention is based on the task, on the practical requirements to design a gas pressure regulator that meets the needs of the different Fastening options in the bottle crate of the vehicle and the associated ones different line routing for the gas inlet and gas outlet connection allows. Another requirement is that the gas pressure regulator housing is made of metal to keep the vehicle vibrations as light as possible in its mass, on the other hand but a very stable attachment between the housing wall and the connection piece to create so that the shocks while driving do not break at the lead thin housing wall. The one with two diaphragm-controlled valve devices equipped gas pressure regulator is still given the task that if it fails of the first control stage, the downstream second valve device performs the safety control function takes over with the best possible control accuracy.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst, mit einer weiteren Ausbildung nach den Unteransprüchen.According to the invention, this object is achieved by the characterizing features of claim 1 solved, with a further training according to the subclaims.
Der mit der Erfindung erzielbare Vorteil in der Gestaltung des Gasdruckregelgerätes liegt darin, daß die doppelwandige Ausführung des Gehäusemantels eine sehr stabile Verbindung zu den drei Gehäuseanschlüssen schafft, insbesondere eine feste Verwurzelung zu den für die Variierung des Gasausgangs- und Befestigungsanschlusses erforderlichen Wechselstutzen. Die Trennstege zwischen den beiden Gehäusewandungen bieten gleichzeitig die Möglichkeit zur Aufnahme der Schraubenlochbohrungen für die Deckelbefestigungsschrauben, damit verbunden können die sich diametral gegenüberliegenden Membranen für beide Ventileinrichtungen den gleichen wirksamen Durchmesser und eine gleich gute Regelgenauigkeit aufweisen.The advantage that can be achieved with the invention in the design of the gas pressure regulator is that the double-walled design of the housing shell is very stable Connection to the three housing connections creates, in particular, a firm root to those required for varying the gas outlet and mounting connection Interchangeable connector. The dividers between the two housing walls offer at the same time the possibility of receiving the screw holes for the cover fastening screws, connected to this can be the diametrically opposed membranes for both Valve devices have the same effective diameter and an equally good control accuracy exhibit.
Die Erfindung wird nach den Ausführungsbeispielen in den beigefügten Zeichnungen wie folgt beschrieben: Fig. 1 zeigt einen Funktionsquerschnitt des Druckregelgerätes mit den beiden membrangesteuerten Ventileinrichtungen, mit dem Gaseingangs- und dem Gasausgangsstutzen.The invention is illustrated by the embodiments in the attached Drawings described as follows: Fig. 1 shows a functional cross-section of the pressure regulator with the two membrane-controlled valve devices, with the gas inlet and the gas outlet nozzle.
Fig.2 zeigt eine Dr sicSt ruf des Druckregelgerät mit der doppelten Gehäusewandung, mit der Anordnung des Gasausgangsstutzens in gerader Verlängerung zum Gaseingangsstutzen, und 90 Grad dazu versetzt den Befestigungsstutzen, wobei der Gasausgangsstutzen 7 einen wechselbaren Einschraubstutzen 7a und der Befestigungsstutzen 8 einen Einschraubstutzen 8a zeigen, die an Ort und Stelle den verlangten Einbauverhältnissen angeglichen werden können.Fig.2 shows a Dr sicSt call of the pressure regulator with the double Housing wall with the arrangement of the gas outlet nozzle in a straight extension to the gas inlet nozzle, and the fastening nozzle offset by 90 degrees, whereby the gas outlet nozzle 7 has an exchangeable screw-in nozzle 7a and the fastening nozzle 8 show a screw-in socket 8a that meets the required installation conditions in place can be adjusted.
Fig.3 zeigt die gleiche Anordnung, jedoch sind hier für eine Serienfertigung gleicher Stutzenanordnung der Ausgangsstutzen 7b und der Befestigungsstutzen 8b als feste Wechseleinsätze in der Spritzgußform ausgeführt.Fig. 3 shows the same arrangement, but here are for series production the same nozzle arrangement of the outlet nozzle 7b and the fastening nozzle 8b designed as fixed interchangeable inserts in the injection mold.
Fig.4 zeigt den Ausgangsanschluß gegen den Befestigungsanschluß in seiner Anordnung vertauscht.Fig.4 shows the output connector versus the mounting connector in its arrangement reversed.
Der Gaseingangsstutzen 5 des Gasdruckregelgerätes ist durch eine bewegliche Schlauchleitung mit der Flüssiggasflasche verbunden und hat eine feste Stellung zur Regeldüse 6. Der zu regelnde Ausgangsdruck, z. B. 1,5 bar, wird an der Regelventilfeder 16 mit der Madenschraube 17 eingestellt und durch die Regelventilmembran 13 in Verbindung mit dem Regelventilstellglied 18 in einen konstanten Ausgangsdruck umgesetzt.The gas inlet connection 5 of the gas pressure regulator is movable by a Hose line connected to the liquid gas bottle and has a fixed position to the regulating nozzle 6. The outlet pressure to be regulated, e.g. B. 1.5 bar, is attached to the control valve spring 16 set with the grub screw 17 and connected by the control valve membrane 13 implemented with the control valve actuator 18 in a constant output pressure.
Dieser vorgeregelte Zwischendruck gelangt durch die geöffnete Druckbegrenzungsdüse 15 zum Gasausgangsstutzen 7, der an eine feste Rohrleitung angeschlossen ist, die zu dem nicht dargestellten, außerhalb des Flaschenkastens angeordneten Versorgungsdruckregelgerät führt. Die Druckbegrenzungsmembran 14 wird durch Einstellung eines höheren Gegendruckes an der Druckbegrenzungsfeder 19,entsprechend z. B.This pre-regulated intermediate pressure passes through the open pressure relief nozzle 15 to the gas outlet nozzle 7, which is connected to a fixed pipeline, the to the supply pressure regulator, not shown, arranged outside the bottle crate leads. The pressure relief membrane 14 is adjusted by setting a higher counter pressure on the pressure relief spring 19, corresponding to z. B.
1,75 bar, das Druckbegrenzungsventilstellglied 20 in geöffneter Stellung halten, solange auf der Regelventilseite 21 keine Störung auftritt. Erhöht sich durch irgendeinen Störfall der Druck im Regelventilraum 21, so gelangt dieser durch die geöffnete Druckbegrenzungsdüse 15 in den Druckbegrenzungsventilraum 22, wirkt auf die Druckbegrenzungsventilmembran 14 und bringt diese gegen den auf z. B. 1,75 bar eingestellten Begrenzungsdruck in eine Schließstellung oder im Falle einer Gasabnahme in eine Regelstellung auf den etwas erhöht eingestellten Ausgangsdruck von 1,75 bar. Hier wirkt sich nun die auf den gleichen Durchmesser wie die Regelventilmembran 13 gebrachte Druckbegrenzungsventilmembran 14 günstig auf das weitere gestörte Regelverhalten aus. Die Anordnung des Gasflaschenkastens ist bei verschiedenen Fahrzeugtypen unterschiedlich. Wohnwagenanhänger haben meist außenliegende Flaschenkästen, Wohnmobile dagegen eingebaute Flaschenkästen; daneben gibt es noch weitere Ausführungen, die eine unterschiedliche Placierung des Druckregelgerätes erfordern und damit auch den Gaseingangsanschluß zum Gasausgangsanschluß im geradlinigen - oder Winkelverlauf verlangen. Um dieser Forderung nachzukommen, sind an diesem Druckregelgerät der Gasausgangsstutzen 7 und der Befestigungsstutzen 8 so angeordnet und ausgebildet, daß diese in ihrer 90-Grad-Stellung gegeneinander vertauscht werden können. Für eine jederzeit wechselbare Ausführung ist ein Einschraubstutzen 7a für den Gasausgang und ein Einschraubstutzen 8a für den Befestigungsstutzen 8 vorgesehen, deren Lage und Gewindeverbindungen genau aufeinander abgestimmt sind. Bei größeren Serien gleichartig gelagerter Anschlußstutzen werden diese Anschlüsse bereits in der Spritzgußform dem Kundenwunsch entsprechend angeordnet. Die doppelwandige Ausführung des Gehäuses wurde aus Stabilitätsgründen und zur Gewichtseinsparung gewählt. Durch die Erschütterungen beim Fahren werden die Gasanschlußstutzen durch die angeschlossenen Leitungen und der Befestigungsanschluß durch die Masse des Gasdruckregelgerätes belastet. Durch die doppelwendige Ausführung des Gehäuses in eine innere, den Gasdruck aufnehmende Wandung 2 und eine äußere, die Anschlußstutzen stützende Mantelfläche 4 werden die Anschlußstutzen an zwei getrennt voneinander liegenden Verbindungen gefaßt und gegen Ausbrechen aus der Gehäusewandung doppelt gesichert. Ein weiterer Vorteil dieser doppelwandigen Gehäuseausführung liegt in der Gewichtseinsparung, da diese beiden Wandungen dünn gehalten werden können. Die zwischen den beiden dünnen Wandungen liegenden Trennungsstege 3 sind mit Gewindebohrungen versehen und dienen der Befestigung des Regelventildeckels 10 und des Druckbegrenzungsventildeckels 11 mittels Deckelschrauben 12. Das Reglergehäuse bekommt dadurch ein glattes äußeres Aussehen.1.75 bar, the pressure relief valve actuator 20 in the open position hold as long as no malfunction occurs on control valve side 21. Increases if the pressure in the control valve chamber 21 is caused by any incident, it will pass through the open pressure-limiting nozzle 15 acts in the pressure-limiting valve chamber 22 on the pressure relief valve membrane 14 and brings it against the z. B. 1.75 bar set limiting pressure in a closed position or in the In the event of a gas consumption in a control position to the slightly higher set Outlet pressure of 1.75 bar. Here the affects the same diameter like the control valve membrane 13 brought pressure relief valve membrane 14 favorable on the further disturbed control behavior. The arrangement of the gas bottle case is different for different vehicle types. Caravan trailers usually have external bottle crates, mobile homes, on the other hand, built-in bottle crates; Besides there are other versions that require different placement of the pressure regulator require and thus also the gas inlet connection to the gas outlet connection in a straight line - or request an angle course. In order to meet this requirement, are on this Pressure regulator, the gas outlet nozzle 7 and the fastening nozzle 8 are arranged and designed that these are interchanged in their 90-degree position can. A screw-in socket 7a for the gas outlet and a screw-in socket 8a for the fastening socket 8 are provided, whose position and thread connections are precisely matched to one another. With larger ones These connections are already made in series of similarly mounted connection pieces the injection mold arranged according to customer requirements. The double-walled version of the housing was chosen for reasons of stability and to save weight. By the vibrations when driving are connected to the gas connection nozzle Lines and the fastening connection through the mass of the gas pressure regulator burdened. Due to the double-turn design of the housing in an inner one, the gas pressure receiving wall 2 and an outer jacket surface supporting the connecting pieces 4, the connecting pieces are connected to two separate connections captured and doubly secured against breaking out of the housing wall. Another The advantage of this double-walled housing design is the weight saving, since these two walls can be kept thin. The thin one between the two Separating webs 3 lying on the walls are provided with threaded holes and are used the fastening of the control valve cover 10 and the pressure relief valve cover 11 by means of cover screws 12. This gives the controller housing a smooth exterior Appearance.
