Definitions
- the invention relates to a system for ventilation of tankers, in particular road tankers, according to the preamble of claim 1.
- a system for ventilation of tankers, in particular road tankers, according to the preamble of claim 1.
- Such a system is known, for example, from FR-A-1379210.
- Road tanker tanks must be equipped with a ventilation system that ensures gas exchange with the filling station or the floor tank to be filled when filling or emptying the tank using the gas pendulum process. After the tank of the road tanker has been filled or emptied, the ventilation system is normally closed. However, breathing must remain possible when the tank pressure exceeds or falls below a predetermined pressure. In the event of a collision, for example after the tanker vehicle overturns, the ventilation system is usually subjected to a higher pressure than the pressure that leads to the ventilation system opening when breathing.
- the lines adjoining the tilt valve are usually led down through the tank compartments and end there at the gas collection or gas pendulum connection.
- DE-U-8630947 describes a system for ventilation on tank trucks with a controllable ventilation valve in the top of the tank truck, which is connected directly underneath the top of the tank truck to the upper end of a pipe guided from the underside of the tank truck to the outside of the tank truck is. Valve and pipe are therefore at significant risk if the car overturns due to an accident.
- the invention has for its object to provide a ventilation system for tankers, especially road tankers, which is inexpensive to manufacture with a simple structure and ensures increased security compared to known systems.
- the invention provides that the ventilation system is not, as in the prior art, attached to the top of the tank, in particular the dome cover, but is located at the upper end of a standpipe directly below the top of the tanker, which is vertical from the bottom of the tank Direction is passed through the tank.
- No ventilation opening is required in the tank top of the tank truck, since the ventilation pipes are arranged on the tank bottom of the tank truck together with the loading and unloading pipes.
- the ventilation system is secured by the top of the tank itself.
- the omission of the dome fittings increases the safety of the tank against leakage due to external influences. Neither roll bars nor dome tubs are required.
- the breathing valve can be simplified, since when the vehicle overturns, only the gas pressure in the gas space of the tank compartment has to be taken into account. There is no longer any static pressure on the ventilation system as soon as the standpipe is also filled with liquid when the tanker vehicle is overturned.
- the detonation and permanent fire safety devices that are required for each tank compartment can be combined in a compact housing on the underside of the tanker vehicle and also contain gas collection or gas pendulum connections. This fuse can also be combined with the ventilation system to form a unit at the upper end of the standpipe.
- the ventilation system is arranged at the end of an at least right-angled bend in the upper end of the standpipe.
- FIG. 1 shows a tank compartment 1 through which a standpipe 4 is passed in the vertical direction. This is passed through the tank wall at the tank bottom 5.
- the ventilation system 3 is arranged directly below the top of the tank 2 at the upper end of the standpipe 4.
- This can be constructed in a conventional manner, namely in particular have a valve function which releases a large cross-section when the tank compartment is emptied or emptied, the valve being controlled hydropneumatically.
- a second valve function is used to breathe the interior of the tank.
- This valve function contains spring-loaded pressure or vacuum valves that respond when a certain pressure is reached and release a smaller cross-section.
- the actuation line for actuating the valves is either routed parallel to the standpipe or within the standpipe.
- a detonation and permanent fire safety device constructed in the usual way is used, which either outside the tank space in the connecting piece of the standpipe, inside the tank immediately in front of the ventilation valve 3 or with the ventilation system Unit can be summarized.
- the standpipe leads outside of the tank 1 to a distributor valve 6, which can be connected either to a gas manifold connection 8 with gas manifold 9 or to a gas pendulum connection 7 with gas pendulum line 11, depending on whether the tank is being filled or emptied.
- Fig. 2 shows a detailed view of the invention.
- the standpipe 4 ends directly below the top of the tank and in an arc 12, at the end of which the ventilation valve 3 is arranged. This ensures that a surge of liquid possibly entering the standpipe 4 before the valve closes cannot get into the collecting lines, but can initially flow back out of the bend 12 into the tank.
- Fig. 3 shows a holding shoe which is used for the vertical guidance of the standpipe 4, without this having any effect on the statics of the tank compartment. This ensures that the standpipe 4 is secured against horizontal tilting.
- the holding shoe 13 can consist, for example, of a ring attached to the top of the tank 2 and loosely guided around the standpipe 4, which prevents the standpipe from escaping to the side.
- the openings of the valves are located within the expansion space of the tank compartment filled with gas phase, so that the valves have to be arranged directly below the top of the tank.
- the invention can be used not only on road tankers, but in particular also for tank wagons.

Abstract
Description
Die Erfindung betrifft ein System zur Be- und Entlüftung an Tankwagen, insbesondere Straßentankwagen, nach dem Oberbegriff des Anspruchs 1. Ein derartiges System ist z.B aus der FR-A-1379210 bekannt.The invention relates to a system for ventilation of tankers, in particular road tankers, according to the preamble of claim 1. Such a system is known, for example, from FR-A-1379210.
Tanks von Straßentankwagen müssen mit einem System zur Beund Entlüftung versehen sein, das beim Befüllen bzw. Entleeren des Tanks unter Anwendung des Gaspendelverfahrens einen Gasaustausch mit der Befüllstation bzw. dem zu befüllenden Bodentank gewährleistet. Nachdem der Tank des Straßentankwagens befüllt bzw. entleert ist, ist das System zur Be- und Entlüftung normalerweise geschlossen. Allerdings muß ein Atmen bei Über- bzw. Unterschreiten eines vorgegebenen Tankinnendruckes möglich bleiben. Im Kollisionsfalle, beispielsweise nach einem Umsturz des Tankfahrzeuges, lastet auf dem Be- und Entlüftungssystem zumeist ein höherer Druck als der Druck, der beim Atmen zum Öffnen des Lüftungssystems führt.Road tanker tanks must be equipped with a ventilation system that ensures gas exchange with the filling station or the floor tank to be filled when filling or emptying the tank using the gas pendulum process. After the tank of the road tanker has been filled or emptied, the ventilation system is normally closed. However, breathing must remain possible when the tank pressure exceeds or falls below a predetermined pressure. In the event of a collision, for example after the tanker vehicle overturns, the ventilation system is usually subjected to a higher pressure than the pressure that leads to the ventilation system opening when breathing.
Überlicherweise befindet sich auf dem Tankscheitel in einer Öffnung des Domdeckels ein Kippventil, das verschiedene Funktionen hat:
- a) Beim Befüllen bzw. Entleeren des Tanks wird das Kippventil pneumatisch in der Weise betätigt, daß ein großer Querschnitt für hohe Gasvolumenströme freigegeben wird.
- b) Zum Atmen des Tanks (thermischer Ausgleich, Entgasung) sind federbelastete Über- bzw. Unterdruckventile vorgesehen, die bei Erreichen eines vorgegebenen Drucks eine Öffnung freigeben.
- c) Für den Kollisionsfall werden die Über- bzw. Unterdruckventile durch eine zusätzliche Gewichtsbelastung auf einen erhöhten Öffnungsdruck eingestellt.
- a) When filling or emptying the tank, the tilt valve is actuated pneumatically in such a way that a large cross section is released for high gas volume flows.
- b) To breathe the tank (thermal compensation, degassing) spring-loaded pressure and vacuum valves are provided, which open an opening when a predetermined pressure is reached.
- c) In the event of a collision, the pressure and vacuum valves are set to an increased opening pressure by an additional weight load.
Üblicherweise schließt sich an das Lüftungssystem eine Detonations- und Dauerbrandsicherung an. Es folgen Verteilerventile zur Umsteuerung der Be- und Entlüftung.Detonation and continuous fire protection usually follow the ventilation system. Distributor valves for reversing the ventilation follow.
Die sich an das Kippventil anschließenden Leitungen werden üblicherweise durch die Tankabteile nach unten geführt und enden dort an Gassammel- bzw. Gaspendelstutzen. Es ist aber auch bekannt, die Leitungen zur Vermeidung einer aufwendigen Bauweise im Inneren der Tankabteile außen am Tankfahrzeug herum nach unten zu führen. In jedem Fall ist es jedoch erforderlich, Leitungen vom Be- und Entlüftungssystem, das am Tankscheitel befestigt ist, zur Unterseite des Tankfahrzeuges zu führen.The lines adjoining the tilt valve are usually led down through the tank compartments and end there at the gas collection or gas pendulum connection. However, it is also known to lead the lines downward around the outside of the tanker in order to avoid a complex construction inside the tank compartments. In any case, however, it is necessary to run lines from the ventilation system, which is attached to the top of the tank, to the underside of the tanker.
Zum mechanischen Schutz der Armaturen am Tankscheitel gegen äußere Einwirkungen bei einem Unfall sind aufwendige bauliche Schutzeinrichtungen wie Domwanne oder Überrollbügel erforderlich. Es ist auch schon vorgeschlagen worden, den Domdeckel mit aufgesetzten Domarmaturen vertieft im Tankscheitel so anzuordnen, daß der Tankmantel selbst eine Schutzfunktion übernimmt.In order to mechanically protect the fittings on the top of the tank against external influences in the event of an accident, complex structural protection devices such as a dome trough or roll bar are required. It has also already been proposed to arrange the dome cover with attached dome fittings in the tank top so that the tank jacket itself assumes a protective function.
Aus der DE-OS 29 14 738 ist ein Standrohr für eine Gaspendelleitung bekannt, die am oberen Ende mit einer Halterung am Tankscheitel verbunden ist, durch die das Standrohr axial verschiebbar, jedoch gegen seitliches Ausweichen, gesichert ist. Bei dieser Anordnung ist das Atmungsventil am Tankkopf befestigt, während das Standrohr allein zur Gaspendelung dient und die verschiebliche Verbindung zwischen Gaspendelrohr und Atmungsarmatur einen Schwallschutz bildet.From DE-OS 29 14 738 a standpipe for a gas suspension line is known, which is connected at the upper end to a holder on the top of the tank, through which the standpipe is axially displaceable, but secured against lateral evasion. In this arrangement, the breathing valve is attached to the tank head, while the standpipe is used solely for gas oscillation and the sliding connection between the gas pendulum pipe and the breathing valve forms a surge protection.
Die DE-U-8630947 beschreibt ein System zur Be- und Entlüftung an Tankwagen mit einem steuerbaren Be- und Entlüftungsventil im Tankwagenscheitel, welches unmittelbar unterhalb des Tankwagenscheitels mit dem oberen Ende eines von der Unterseite des Tankwagens an der Außenseite des Tankwagens entlang geführten Rohres verbunden ist. Armatur als auch Rohr sind daher bei einem Umsturz des Wagens durch Unfall erheblich gefährdet.DE-U-8630947 describes a system for ventilation on tank trucks with a controllable ventilation valve in the top of the tank truck, which is connected directly underneath the top of the tank truck to the upper end of a pipe guided from the underside of the tank truck to the outside of the tank truck is. Valve and pipe are therefore at significant risk if the car overturns due to an accident.
Der Erfindung liegt die Aufgabe zugrunde, ein Be- und Entlütungssystem für Tankwagen, insbesondere Straßentankwagen, anzugeben, das bei einfachem Aufbau kostengünstig herzustellen ist und gegenüber bekannten Systemen eine erhöhte Sicherheit gewährleistet.The invention has for its object to provide a ventilation system for tankers, especially road tankers, which is inexpensive to manufacture with a simple structure and ensures increased security compared to known systems.
Diese Aufgabe wird durch die im Anspruch 1 angegebene Erfindung gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in Unteransprüchen angegeben.This object is achieved by the invention specified in claim 1 solved. Advantageous developments of the invention are specified in the subclaims.
Die Erfindung sieht vor, daß das System zur Be- und Entlüftung nicht, wie beim Stand der Technik, im Tankscheitel, insbesondere Domdeckel, befestigt ist, sondern sich am oberen Ende eines Standrohres unmittelbar unterhalb des Tankwagenscheitels befindet, das von der Tanksohle aus in vertikaler Richtung durch den Tank hindurchgeführt ist. Hierdurch ergeben sich beträchtliche Vorteile gegenüber dem Stand der Technik:
Im Tankscheitel des Tankwagens ist keine Lüftungsöffnung erforderlich, da die Lüftungsleitungen zusammen mit den Be- und Entladungsleitungen an der Tanksohle des Tankwagens angeordnet sind. Das Be- und Entlüftungssystem ist durch den Tankscheitel selbst gesichert. Aufgrund des Entfalls der Domarmaturen erhöht sich die Sicherheit des Tanks gegen Leckschlagen bei äußeren Einwirkungen. Es sind weder Überrollbügel noch Domwannen erforderlich. Das Atmungsventil kann vereinfacht werden, da bei Umsturz des Fahrzeuges lediglich der sich im Gasraum des Tankabteils befindliche Gasdruck zu berücksichtigen ist. Es lastet kein statischer Druck mehr auf dem Lüftungssystem, sobald das Standrohr im umgekippten Zustand des Tankfahrzeuges auch mit Flüssigkeit gefüllt ist.The invention provides that the ventilation system is not, as in the prior art, attached to the top of the tank, in particular the dome cover, but is located at the upper end of a standpipe directly below the top of the tanker, which is vertical from the bottom of the tank Direction is passed through the tank. This results in considerable advantages over the prior art:
No ventilation opening is required in the tank top of the tank truck, since the ventilation pipes are arranged on the tank bottom of the tank truck together with the loading and unloading pipes. The ventilation system is secured by the top of the tank itself. The omission of the dome fittings increases the safety of the tank against leakage due to external influences. Neither roll bars nor dome tubs are required. The breathing valve can be simplified, since when the vehicle overturns, only the gas pressure in the gas space of the tank compartment has to be taken into account. There is no longer any static pressure on the ventilation system as soon as the standpipe is also filled with liquid when the tanker vehicle is overturned.
Die Detonations- und Dauerbrandsicherungen, die für jedes Tankabteil erforderlich sind, können in einem kompakten Gehäuse an der Unterseite des Tankfahrzeuges zusammengefaßt werden und außerdem Gassammel- bzw. Gaspendelleitungsanschlüsse enthalten. Diese Sicherung kann aber auch mit dem Be- und Entlüftungssystem zu einer Einheit am oberen Ende des Standrohres zusammengefaßt sein.The detonation and permanent fire safety devices that are required for each tank compartment can be combined in a compact housing on the underside of the tanker vehicle and also contain gas collection or gas pendulum connections. This fuse can also be combined with the ventilation system to form a unit at the upper end of the standpipe.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist das Be- und Entlüftungssystem am Ende einer wenigstens rechtwinkligen Abbiegung des oberen Endes des Standrohres angeordnet.According to a preferred embodiment of the invention, the ventilation system is arranged at the end of an at least right-angled bend in the upper end of the standpipe.
Damit wird verhindert, daß kleine Mengen an Flüssigkeit vor dem Schließen der entsprechenden Ventile in das Standrohr gelangen, sondern wieder aus dem abgebogenen Ende herausfliessen können.This prevents small amounts of liquid from getting into the standpipe before the corresponding valves are closed, but rather can flow out of the bent end again.
Vorzugsweise wird die Steuerleitung zur Betätigung der Ventile parallel zum Standrohr geführt, insbesondere innerhalb des Standrohres. Sofern das Standrohr im größeren Bogen durch ein Tankabteil geführt ist oder beispielsweise mit einer Dehnungsmanschette versehen ist, kann es auch zur Erhöhung der Standfestigkeit am Tankscheitel befestigt sein, ohne daß eine nicht erwünschte Versteifung des Tankraumes eintritt.The control line for actuating the valves is preferably routed parallel to the standpipe, in particular within the standpipe. If the standpipe is guided in a larger arc through a tank compartment or is provided, for example, with an expansion sleeve, it can also be attached to the top of the tank to increase the stability without undesirable stiffening of the tank space.

Fig. 1 zeigt ein Tankabteil 1, durch das in vertikaler Richtung ein Standrohr 4 hindurchgeführt ist. Dieses ist an der Tanksohle 5 durch die Tankwand hindurchgeführt.1 shows a tank compartment 1 through which a
Unmittelbar unterhalb des Tankscheitels 2 ist am oberen Ende des Standrohres 4 das Be- und Entlüftungssystem 3 angeordnet. Dieses kann in konventioneller Weise aufgebaut sein, nämlich insbesondere eine Ventilfunktion aufweisen, die bei Be- oder Entleeren des Tankabteils einen großen Querschnitt freigibt, wobei die Steuerung des Ventils hydropneumatisch erfolgt. Eine zweite Ventilfunktion dient zum Atmen des Tankinnenraums. Diese Ventilfunktion enthält federbelastete Überdruck- bzw. Unterdruckventile, die bei Erreichen eines bestimmten Drucks ansprechen und einen kleineren Querschnitt freigeben.The
Die Erhöhung des Atmungs-Grenzdrucks durch eine zusätzliche Gewichtsbelastung des Ventils im Fall, daß das Fahrzeug umstürzt, ist beim Gegenstand der Erfindung nicht erforderlich, da das System in diesem Fall keinem höheren statischen Druck ausgesetzt ist als im Normalbetrieb und somit nur einem erhöhten Dampfdruck Sicherheit zu bieten hat, sobald das Standrohr auch mit Flüssigkeit gefüllt ist.The increase in the respiratory limit pressure due to an additional weight load on the valve in the event that the vehicle overturns is not necessary for the subject of the invention, since in this case the system is not exposed to a higher static pressure than in normal operation and thus only an increased vapor pressure has to offer as soon as the standpipe is also filled with liquid.
Die Betätigungsleitung zur Betätigung der Ventile wird entweder parallel zum Standrohr oder innerhalb des Standrohres geführt.The actuation line for actuating the valves is either routed parallel to the standpipe or within the standpipe.
In dem Standrohr ist eine in üblicher Weise aufgebaute Detonations- und Dauerbrandsicherung eingesetzt, die entweder außerhalb des Tankraumes im Anschlußstutzen des Standrohres, innerhalb des Tanks unmittelbar vor dem Be- und Entlüftungsventil 3 oder auch mit dem Be- und Entlüftungssystem zu einer Einheit zusammengefaßt sein kann.In the standpipe, a detonation and permanent fire safety device constructed in the usual way is used, which either outside the tank space in the connecting piece of the standpipe, inside the tank immediately in front of the
Das Standrohr führt außerhalb des Tanks 1 auf ein Verteilerventil 6, das entweder an einen Gassammelanschluß 8 mit Gassammelleitung 9 oder an einen Gaspendelanschluß 7 mit Gaspendelleitung 11 anschaltbar ist, je nach dem ob der Tank befüllt oder entleert wird.The standpipe leads outside of the tank 1 to a
Fig. 2 zeigt eine Detailansicht der Erfindung. Das Standrohr 4 endet unmittelbar unterhalb des Tankscheitels und in einem Bogen 12, an dessen Ende das Be- und Entlüftungsventil 3 angeordnet ist. Hierdurch ist gewährleistet, daß ein in das Standrohr 4 vor Schließen des Ventils eventuell eintretender Flüssigkeitsschwall nicht in die Sammelleitungen gelangen kann, sondern zunächst wieder aus dem Bogen 12 in den Tank zurückfließen kann.Fig. 2 shows a detailed view of the invention. The
Fig. 3 zeigt einen Halteschuh, der zur vertikalen Führung des Standrohres 4 dient, ohne daß dies Auswirkungen auf die Statik des Tankabteils hätte. Hiermit wird erreicht, daß das Standrohr 4 gegen horizontales Kippen gesichert ist. Der Halteschuh 13 kann beispielsweise durch einen am Tankscheitel 2 befestigten und um das Standrohr 4 lose geführten Ring bestehen, der ein Ausweichen des Standrohres zur Seite verhindert.Fig. 3 shows a holding shoe which is used for the vertical guidance of the
Um die Funktionsweise des erfindungsgemäßen Be- und Entlüftungssystems zu gewährleisten, ist es erforderlich, daß die Öffnungen der Ventile sich innerhalb des mit Gasphase gefüllten Dehnungsraumes des Tankabteils befinden, so daß die Ventile unmittelbar unterhalb des Tankscheitels angeordnet sein müssen.In order to ensure the functioning of the ventilation system according to the invention, it is necessary that the openings of the valves are located within the expansion space of the tank compartment filled with gas phase, so that the valves have to be arranged directly below the top of the tank.
Die Erfindung ist nicht nur an Straßentankfahrzeugen verwendbar, sondern insbesondere auch für Kesselwagen.The invention can be used not only on road tankers, but in particular also for tank wagons.
