Definitions
- the invention relates to a device and to a method for filling of compressed gas tanks. It refers in particular to the filling of Gas cylinders with flammable gases for heating, cooking, grilling or for craft purposes can be used.
- compressed gas containers are usually reusable containers that are common in the course of their service life be refilled.
- the compressed gas tank filling valves wherein in Germany mainly angle valves with a possibility of actuation via a Spindle are in use.
- the invention also relates to others Compressed gas containers as gas cylinders and on any valve types.
- gas cylinders are after filling with an open angle valve and subsequently screwing the spindle wheel by brushing with Soapy water and observation of possible blistering tested. This The procedure is inaccurate and prone to errors and, moreover, relatively time-consuming.
- U.S. Patent 5,488,461 which is considered to represent the closest prior art, shows the preamble of claim 1, and more particularly a system for leak testing of large gas containers on tank trucks for dangerous gases, especially chlorine.
- This will be a removable hood placed on a valve of the container, which has an angle valve. It will the atmosphere in the hood pumped out and examined by sensors for chlorine residues.
- the invention is based on the technical problem, an improved device and an improved method for filling pressurized gas containers and Check their valves.
- a device for filling is provided a pressurized gas container with compressed gas by means of a filling connection of the device, which can be connected to a valve of the compressed gas tank, which device has a hood which is designed to be filled during filling demarcate closed volume, the filling connection and the Compressed gas container valve includes, and a gas detector, which is designed to Gas components in the connected volume to detect the valve Tightness to check, characterized in that the device is a filling station side first device part with the gas detector and a on the Compression gas container to be attached second device part, which the Be Glallan gleich and a gas connection for the first device part for supplying the filling connection with gas.
- the invention is directed to a method using such Device in which the filling connection for filling at the compressed gas container valve is attached and the compressed gas container valve after filling in closed state is checked for leaks.
- the basic idea of the invention is, already during the filling, So when connected to the compressed gas tank valve filling the Filling device, a closed volume around the filling port and the Define valve around, which can be checked by means of a gas detector.
- the filling of the gas cylinder and the checking of the valve so sort of done in one operation.
- a hood is provided, which is to delineate the completed volume.
- the gas detector is designed to check the volume delimited by the hood. This review can still during the actual filling or even immediately done afterwards.
- the device parts for checking the Tightness and filling to the extent unified that the hood the filling connection and already surround the valve during filling.
- the leak test be completed while the filling connection is still connected to the compressed gas container valve.
- this is not a necessary feature.
- even closer to exploring testing for inner leaks may also make sense in any case for this part of the test, however, the hood remains attached.
- An embodiment of the invention provides that the hood for contact with a Outside wall of the gas cylinder is designed in the vicinity of the valve, so does not have to cover the entire gas cylinder to the one to be checked To demarcate volume. It may rather be a bell-like hood act, which engages over the filling port and the valve during filling.
- the filling connection also between different filling processes, that is, in the state removed from the pressurized gas container, inside the hood arranged.
- the hood and the filling connection thus preferably form a structural unit, as the embodiment illustrates.
- the hood can have any other shapes that the described function enable. It is therefore in the most general sense, a cover that together with the compressed gas tank or otherwise the to be checked Can delineate volume. This volume does not have to be strict Sense to be gas-tight. It suffices to have a demarcation sufficient That escaping gas accumulates in the volume to lighter to be detectable. Alternatively, the volume can be completed in such a way be that it can be pumped out targeted. A tightness in terms of production a vacuum is not absolutely necessary.
- the filling port relative to the hood a bit mobile to keep. This can be avoided that the filling connection at applying and then exerts greater forces on the valve. This is especially true if it is a projecting component on the compressed gas container mounted valve acts. Then there are some assembly tolerances and possibly Also to take into account form tolerances of the gas cylinder itself. The production of a sufficiently final plant can then become a mechanical stress on the valve. In principle, this also applies then, if the hood is not against the pressurized gas container itself, but for example against a base surface, on which this is brought into abutment shall be.
- the described closed volume serves to check for gas components, which leaked during filling or after a leaking valve could be.
- the filling connection itself can also be used for a Leak test are used, in particular for testing on a so-called inner tightness.
- the external tightness means that the valve is tight for a given Connection of a consumer line or the filling connection no gas after leaking outside. So it relates in this example, the tightness of the threaded seat the valve in the pressurized gas container and the tightness of the spindle.
- the internal tightness means that the valve is connected when Consumer line does not leak gas into the consumer line when it is closed.
- a further embodiment has a gripping device in the hood, with the an actuating element of the valve, for example, the spindle wheel, and gripped can be operated.
- the valve can also be operated when the Hood is attached.
- the gripping device is preferably around a head with a complementary to the actuator adapted hollow shape.
- can in this mold spring-mounted pins find use that a certain automatic adjustment allows the shape of the actuator or its location.
- Movable pens are related to universal tools for hex screw heads known.
- the gripping device is preferably tiltable biaxially on the hood held, so that positional tolerances can be compensated, as with the already mentioned movable attachment of the filling connection is the case.
- Essential for the invention is also the bipartite of the device.
- a first device part is equipped with the gas detector and preferably stationary, i. not used as a loose part.
- a second device part has the filling connection, for example, for the angle valve with the spindle wheel, and furthermore has a gas connection, via which the first device part can supply the filling connection with gas.
- this includes second device part of the hood and preferably also the described Gripping device. Then that can through the hood of the second device part volume to be limited via a gas detector connection with the gas detector be connected on the part of the first device part.
- the bipartite has two main advantages. One concerns automation the filling process and is in a later part of the Description explained in more detail.
- a second significant advantage is that the second device part can be configured as an adapter, which is connected to a certain valve type is adapted, however, in turn a connection for has the first device part, which is modeled on another type of valve.
- the first device part can be equipped so that it in turn acts as a filling device when the appropriate valve type occurs.
- the invention aims at a design of the second device part, ie of the adapter, for a conventional angle valve with spindle wheel and on the other hand an interpretation of the first device part for a simpler so-called. Straight valve with simple non-return valve, which has no actuator.
- the first part of the device associated "side" of the second Device part as I said designed so that they are modeled on the straight valve is.
- compressed gas containers with a different valve type filled in a planned actually for another valve type filling and be checked are made.
- the gas line opening provided for the connection of the first device part of the straight terminal to the second device part can thereby be surrounded by a concentric groove. Additionally or alternatively, such Groove be provided on the side of the second device part. This allows one of the orientation of the connectors in the connection of the two Device parts independent connection one for the already described Check the filling connection provided test line to the first device part. So if on either side with a suitable radius opposite the gas line opening provided a conduit opening of this test line is, it hits in each angular position on the concentric groove on the opposite side. This applies even more to bilateral grooves.
- first device part facing straight terminal of the second device part at least one, preferably two, about an axis perpendicular to the filling direction axis rotatable gear before. If you think of one in general upright out standing pressurized gas container, the filling direction is in the Usually vertical, so that the gear axis is horizontal. This corresponds to the Arrangement in the embodiment.
- the gear is used for coupling to a below the straight-line connection on the side of the second device part another gear, in turn, with the already described gripping device is coupled. The gripping device can then be rotated over the gears, for example, to open or close a spindle wheel.
- the method according to the invention initially provides the valve tightness at least immediately after filling in the closed state of the valve.
- valve types where a distinction is made between internal and external tightness can only be clarified when the valve is closed, whether the inner tightness is present.
- it is already during the Filling or at least still with the valve open the closed volume examined. Gas components detected either point to leaks Connection of the filling connection or to a problem of external tightness, For example, a leaking connection between the valve and the compressed gas container or a spindle leak. If the completed volume already after connecting the filling connection, but still before Opening the valve, checked, can be leaking after the Exclude filling connection.
- valve closing Connection between valve and gas cylinder is leaking or a Sealing point outside the actual valve is leaking, for example, the spindle.
- a further embodiment of the method according to the invention is directed the use of the device described by exploiting their multipartite.
- the second device part should be present several times and already be mounted in preparation for the filling process. So there are several Compressed gas container with corresponding second parts of the device for filling prepared. This could also be done manually. Then you can do that in this way prepared compressed gas container with the respective second device part the first device part are supplied, which are arranged directly at the filling station is.
- the described filling and testing process By coupling the two parts of the device, the described filling and testing process. Thereafter, the compressed gas container with the second device part removed and elsewhere from the second device part be freed. The latter can then be reused.
- another embodiment of the method relates to an equipment the compressed gas tank with transponders.
- an at least partially automated Filling and testing system can be so easily allocations between different data and the gas cylinders.
- the transponder before filling the compressed gas containers be attached (or in principle to these are provided) with initially determined input data such as tare, bottle size, bottle owner and the like.
- a computerized control of the plant can be the then track individual gas cylinder through the entire process.
- the Transponders can continue to write the results of the leak test serve, especially in the negative case, so in case of leaks. Insofar as the device in the test in the manner already mentioned statements can make about the nature of the leak, they can be held with it and provided for a later manual check or repair become.
- the transponder can be used to save via a scale serve at the filling station determined filling quantity, so that the EDP control in total belonging to the compressed gas tank and for billing or the customer has essential data available.
- the transponder technology allows while an unobstructed handling of the gas cylinders without Consideration of certain specified processing sequences and avoids Allocation error.

- the internal thread connection 10, the angle valve 3 couples to a double line 11 containing Cylinder 14 and is held horizontally displaceable contrast.
- In order to the filling connection 9 can be manually or by motor (concrete pneumatic) be screwed onto the external thread of the angle valve 3. This connection takes place without disturbing application of force by the rest of the gas cylinder resting weight of the second device part 2, because of the filling 9 held vertically displaceable relative to the second device part is and is burdened only by its own weight.
- FIG. 1 clearly shows the spindle wheel 4 mounted on top of the angle valve 3. This is supported by a gripping device 15 with a plurality of vertically spring-mounted Pins 16 gripped.
- the gripping device 15 is otherwise substantially from a prismatic tube piece surrounding the pins 16 radially on the outside and one lying radially inside the pins 16 and on the top of the Spindle wheel 4 resting further prismatic pipe section.
- the gripping device 15 is at a in the radially inner cylinder inside engaging Ausballung 17 a drive shaft 18 is held.
- the Ausballung has in the illustrated in Figure 1 Cross-sectional view circular outer contours, but in one vertical cross-sectional direction with vertical viewing direction a polygon cross-section.
- This polygon cross section is the inner profile of the upper tube piece of Gripping device 15 adapted.
- the gripping device 15 at the balancing 17 rotationally fixed, but kept tiltable about horizontal axes.
- the Connection between the Ausballung 17 and the gripping device 15 vertically movable, wherein the gripping device 15 via a coil spring 19 at an upper side the hood 7 is supported.
- the coil spring 19 thus pushes the Gripping device 15 on the spindle wheel 4, but can when placing and when opening the spindle wheel 4 move upwards.
- FIG. 2 shows the second device part in side view, wherein the dashed lines shown lines 27 and 28 are covered by a hood.
- the wires 27 and 28 are on the not visible in Figure 2 back of the second device part 2 in a similar way a second time.
- FIG. 2 shows a manual drive wheel, which is an alternative to the represents mentioned pneumatic drive. (For pneumatic drive, for example Provide the indicated in Figure 1 coupling part.) It can be seen Furthermore, that the outer line 27 at its lower end in the already with reference to FIG 1 explained double line 11 opens into the filling port 9.
- the two outer lines 27 each to one of the two halves of the double line 11th connected.
- the two outer lines 27 open at its upper end in a non-illustrated and executed in the solid wall of the collar 20 respective line.
- One of these lines is connected to the central gas line 24 the block 25 connected; the other with the groove 26 of the block 25.
- These are the Lines by lying in Figure 1 above and below the plane solid connections of the block 25 with the collar 20 out.
- the gas line in the block 25 is connected to one half of the double line 11 and the groove 26 with the other.
- the two further outer lines 28 are at their lower end to the volume 8 connected in the bell 7 and at its upper end also in the massive wall of the collar connected 20 trained wires that each with an associated peripheral part of a on a lug 29 of the collar 20 formed upper groove 30 are connected.
- FIG. 1 shows in the upper area the first device part 1, which likewise has a Hood 31 has.

- This block 34 is one with a Ring gear 37 bottom closing and rotating driven cylinder 38 surrounded.
- the ring gear 37 is complementary to the tops of the gears 22nd educated.
- the terminals 32 come to rest on the grooves 30 and thus the lines 33 connected via the lines 28 to the volume 8 are. Further, the ring gear 37 engages the gears 22, so that over the cylinder 38, the spindle wheel 4 can be operated. This operation takes place via a not shown pneumatic drive device automatically. Furthermore, the Groove 36 connected in the lowered state with the groove 26. This can be a not shown connecting line of the groove 36 to one of the two halves of Double line 11 can be connected in the filling connection. To the other Half of the double line 11, the central gas line 35 of the block 34 is connected.
- the central gas line 35 with the respective gas cylinder valve connected, in one case directly and in the other case over the described and to the one half of the double line 11 of the filling 9 leading way.
- the area immediately rinsed the angle valve 3 and examined for gas fractions. This serves the Filling connection 9 not only for filling itself, but when using the second device part 2 also for leak testing.
- the actual use is preferably as follows: First, on a number of gas bottles mounted respective second device parts 2, wherein the internal thread connection 10 of the filling connection 9 is retracted. This can then with simultaneous pneumatic rotation of the axis 13 and thus turning the internal thread of the terminal 10 connected to the angle valve 3 become. In this case, the vertical displaceability of the filling connection 9 inaccuracies in the location of the angle valve 3 or the shape of the gas cylinder compensate.
- gripping device 15 engages with the force of Spiral spring 19 acts on the spindle wheel 4. This remains initially closed.
- the gas cylinders become one with the first device part 1 equipped filling station, where the device parts are mechanically coupled become.
- the gas line 35, 24, 27, 11 is supplied with gas.
- About the Volume 8 can now be checked via the lines 28, 30, 32, 33, whether the connection the filling connection to the angle valve 3 is tight. If this is the case, the spindle wheel 4 is turned on and thus the angle valve 3 is opened. While of filling the volume 8 is still checked. In case of detection of a Gas component must be an external leak, since the connection between Filling connection 9 and angle valve 3 has already been checked. In this case the spindle wheel 4 can be turned off again by a motor. If the gas share now disappears, so the spindle is leaking. If he stays, then the seat of the External thread 5 of the corner valve 3 in the gas cylinder leaking.
- the spindle wheel can 4 are switched off by motor when filling is complete. Now the to Filling used line relaxed and flushed. After sufficient rinsing It is possible to check whether gas shares are present in front of the closed gas line Angle valve 3 can be detected. This test corresponds to the examination on the inside Tightness.
- the first device part 1 of the second device part. 2 be removed again, whereupon the next gas cylinder with another second device part is the turn.
