Description

CONNECTION SYSTEM FOR A PRESSURE GAS BOTTLE FIELD OF THE INVENTION The present invention relates to the field of pressurized gas technology. It refers to a pressurized gas bottle, which comprises a check valve included in the neck of a pressurized gas bottle, which is equipped with a connection opening for the gas discharge and which can be operated from the The outer part by means of a rod lifts the valve displaceable along a central axis, as well as a connection device, which can be connected in a detachable and gas-tight manner and which contains the means for actuating the lifting rod. valve A connection system of this type is known, for example, from EP-A2-0 108 972.

BACKGROUND OF THE INVENTION At present, the most exhausting gases are used in many fields, however manual trained personnel are not always available for the exchange of empty bottles. An example is presented here. preparation of beverages in gastronomy and the administration of patients in the field of medicine with vital gases or other important gases (oxygen, nitrous oxide, etc.). Especially in medicine can depend the saluiji and indeed the life of connecting in a short time the bottle of the correct gas. The connection system used today consists of; in these fields a key with a connection thread for a pressure reducing valve or a gas conduit. The key works through a spindle and a valve bell with a seal against the pressure in the bottle. The connection threads are regulated. However, its multiplicity is limited so that only sufficient possibilities are presented to provide a coding of the connection system according to the different types of gases. In addition, a nut cap must normally be removed, which in most cases requires a larger wrench. An additional complexity is that there are left and right threads that when connecting the bottle must first be identified with an implicit loss of time. It is also necessary to use considerable force for the opening of the tap in the case of spindles that no longer have an easy transit.

In the document mentioned in the introduction a connection system is already proposed, which is especially suitable for incinerable fluid gases. With this known system the pressurized gas bottle is equipped with a valve of the gas bottle configured as a check valve, in which a control valve can be included in a waterproof and lockable manner. A rod seated in the control valve operates when the check valve is inserted, so that a faster connection is achieved in conjunction. The known connection system, however, has several disadvantages: - No special coding is provided. of the connection and can not be extended further. The connection procedure itself must be performed between the insert valve and the gas bottle valve carefully due to the lack of a guide so that the control valve sits correctly on the valve of the gas bottle. The insertion of the control valve requires equal to a great use of force. - The system is suitable above all for fixed pressure gas bottles in which the con- trol valve is inserted. A safe support of the bottles is not required with this what in the case of small pressure gas bottles used in medicine and gastronomy can lead to problems. - The check valve firmly installed in the bottle is seated on the screw thread. For example, if in the case of a bottle fall the gas bottle valve is cut, the contents of the bottle are unprotected, which can lead to significant safety risks.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a connection system for pressurized gas cylinders, which makes possible a rapid exchange and connection respectively of the bottles, guarantees a greater security against faults and damages, which makes possible a handling and safe care of bottles and provide multiple coding possibilities. The object of the present invention is solved by a connection system of the type mentioned above, so that the pressurized gas bottle together with the check valve and the connection device can be mechanically coupled transversely to the central axis and outside the The axis of oscillation included to the central axis and in the coupled condition can be joined through an oscillation relatively to each other around the axis of oscillation. Through the mechanical coupling of the connection device and the check valve on an oscillation axis, a fixed positioning between the two parts of the system is first achieved, so that with a consecutive oscillation the folded part is guided in a safe manner. Due to the fixed oscillation axis, a rotation of both parts against each other around the central axis is not possible, whereby a plurality of coding possibilities is achieved. In the event that an oscillating movement of the pressurized gas bottle is specifically carried out with a fixed connection device, the oscillation of the (heavy) bottle can be exploited, to cause a gas-proof correction with a force application reduced. A first preferred embodiment of the connection system according to the present invention in which the check valve comprises a screw cone concentric to the central axis and through a conical rope included in the screwing cone can be screwed into the neck of a pressurized gas bottle, at the outer end of the screwing cone is formed an essentially rectangular connection plate that rests in a direction transverse to the central axis, in whose upper part the connection opening is housed, the oscillation axis is determined by a pair of pins, which are formed at two opposite ends of the connection plate and two pairs of pins are molded on the connection plate, which determine two selectable useful oscillation axes, which are placed symmetrically in relation to a central avenue that runs through the central axis? .. With the help of one of the pairs of spikes can be to easily hang the pressurized gas bottle provided with the check valve with a fixed support and it can be turned in this hanging condition. The other pair of pins is especially suitable in the rotated condition to drive and lock the connection. The symmetrical arrangement of the pairs of pins ensures that the bottle even with a 180 ° rotation around the central axis can be connected without problems since both pairs of pins in that case simply change their function. A second preferred embodiment of the connection system according to the present invention in which the connection opening is configured as a cone that opens outwards and is concentric toward the central axis, in the wall of the opening cone there is a surrounding concentric sealing ring, and the connecting device comprises a gas intake head, which in its anterior zone is configured as a seated insertion cone adapted to the opening cone and when connecting it to the check valve and the The connection is sealed in the opening cone. By this, it is achieved that when oscillating both installation parts (connecting device and check valve) relative to each other an outward sealing is possible, before the final position of the oscillation is reached. In this way, an outward gas management during the connection process is avoided, also when the check valve opens automatically when connecting through the means to activate the valve lift rod. A further preferred embodiment of the invention in which a coding means is included in the check valve and in the connection device, which allows a command connection of the pressurized gas bottle and the connection device only for the pressurized gas bottles adapted to the connection device, and the coding means comprises a concave toothed internal shape arranged concentrically in relation to the central axis in the area of the connection opening and a convex toothed external shape which adapts to the first in the area of the gas intake head. Due to the rotation-proof arrangement between the check valve and the connection device after the mechanical coupling, a wide plurality of coding possibilities is achieved by means of this type of coding. A particularly preferred additional embodiment according to which the connection device comprises a reducing valve with a spring loaded membrane, the means for actuating the valve lifter rod comprises a push rod driven by the membrane, which when connecting the check valve and the connection device has effect on the riser valve, the connection device comprises a fixed wall support for the reception of the pressurized gas bottle conditioned with the check valve, to which it is fixed the reduction valve with return spring, the check valve comprises a screw cone concentric to the central axis and can be screwed by means of a conical rope arranged in the screw cone on the neck of the bottle of the pressurized gas bottle , an essentially rectangular connection plate is formed at the outer end of the screwing cone , which rests transversal to the central axis, in whose upper part the connection opening is housed, the oscillation axis is determined by a pair of pins, which are formed at two opposite ends of the connection plate, the support of the wall It comprises two parallel loading arms, which have at their free end suspension openings in which the connection plate can be hung with its pins,, r in such suspension openings the connection plate can oscillate in the determined axis of oscillation by the spikes. In this mode the bottle is hung where the suspension openings are held there before the final connection. By means of a slight oscillation, which is conveniently achieved by the weight of the bottle, the connection can be achieved safely and without difficulties, so that the opening of the check valve is automatically carried out through the driven driving rod. by the reducing valve. Likewise, in the exchange of bottles, the union can be loosened first by means of a return oscillation without the bottle (still hanging on the loading arms) having to support itself. Additional modalities are presented from the dependent claims.

DETAILED DESCRIPTION OF THE FIGURES The connection system according to the present invention can be used basically in the most different functions and respective variants in an advantageous manner, where the same connection parts can always be used on the side of the bottle. In Figures 1 to 4, four possible variants are represented. In Figures 1 and 2 there is illustrated a connection system 1 and 21 respectively with the previously regulated pressure connection, which is especially suitable for fluid gases, in which the pressure of the bottle declares very little or nothing about the content residual or for highly compressed gases in which no indication of residual pressure is required. The pressurized gas bottle 5 comprises a check valve 4 screwed into the neck 15 of a bottle, which when connected is connected to a reducing valve 2. A spring that is in the reducing valve 2 (46 in Figure 6) ) opens when connected through a discharge rod (51 in Figure 6) to check valve 4.

When the set pressure is reached, it is compressed through the membrane (48 in Figure 6) to the spring 46, whereby the drive rod 51 moves back and the check valve is closed again. In addition, a pressure gauge 8 and an overpressure valve 7 can be additionally provided in the reducing valve 2. The connection is made in a central axis 6. For pressurized gas cylinders 5 max. small is provided according to Figure 1 a wall support 3, which can be screwed firmly by means of fixing plate 9 to the wall or directly to an appliance. In the fixing plate 9, two parallel plate-shaped loading arms 12 are provided (in FIG. 1 only the front loading arm can be seen), which are connected to each other through a loading plate 11 that rests among them. In the loading plate 11, the reducing valve 2 is fixed by recoil springs with its gas administration head (52 in FIG. 6) lower than here illustrated in more detail. The loading arms 12 have suspension openings (58 in Figure 9 (a)) and locking openings (57 in Figure 9 (a)), in the - which The pressurized gas bottle 5 can be hung on the formed pins Ola, b; 32a, b in Figure 5 (b)) in the pins formed above in the check valve 4 and can be connected and locked respectively by light pressure against the wall. In the locked position, the bottle is secured by means of the connection lever 14, which is mounted on the support arms 12 in an oscillating manner about an oscillation axis 10 and is tensioned by means of a spring 13. The bottle Empty pressure gas 5 is released by light pressure against the connection lever 14. Here it remains in its suspended condition and thus is secured against a fall. In the connected and locked condition respectively, the bottle does not require any additional assurance (through chains or similar), as is essential in common connection systems. The mobile connection according to Figure 2 is predominantly provided for large bottles of pressurized gas. This comprises a mobile support 20 with two parallel forks 19, between which a loading plate 16 is arranged in the same way to fix the reduction valve 2. The support 20 is suspended with the forks 19 inclined on both straight pins (32a, b in Figure! 5 (b)) to check valve 4 and connected downwards. Interlocking is also performed here on both additional pins (31a, b in Figure 5 (b)) and in fact by means of a cranked lever system, which comprises an operating lever 17 and a locking lever 18.

Figures 3 and 4 illustrate a connection system according to the present invention with a direct pressure connection, which can be used above all for highly compressed gases with a residual pressure indication and for conduit connections with no pressure. decreased respectively. Instead of a reducing valve there is provided here a manually operated device 23, by means of which the check valve 4 can be opened via a spindle 25 or a drive rod. In the manually operated device 23 a connection 24 for gas administration is provided, in which a conventional pressure reducing valve can also be provided. As in the examples of the embodiments of Figures 1 and 2, the wall support 3 (Figure 3) or the mobile support 20 (Figure 4) can also be optionally used here. The outer configuration and the internal structure of the check valve 4 screwed to the pressurized gas bottle 5 are illustrated in Figure 5, where the partial figures (a) and (b) present the side view and the top view, respectively , and the partial figure (c) illustrates the longitudinal cut in exploded representation. The check valve 4 consists of a screw cone 28 with a conical chord 29 placed outwards, which is adapted to the corresponding inner chord in the neck of the bottle 15 of the pressurized gas bottle 5. In the upper end of the screwing cone 28 is molded! an essentially rectangular connecting plate 27, which rests transversely to the central axis 6. In the upper part of the connection plate 27 is alloyed; to a connection opening 30, which is configured as a cone that opens outwards and concentric to the central axis 6. In the wall of the opening cone there is housed a concentric surrounding sealing nut 36, which resides an O-ring (56 in Figure 7). As the coding means, an inner concave indentation 35 is provided, arranged concentrically to the central axis 6 in the area of the connection opening 30, which when connecting the pressurized gas bottle 5 is adjusted with an indented convex outer shape (FIG. 6, 8) which is adapted to the first, in the area of the gas administration head 52. The indentation of the inner form 35 and the outer form 53 extends in three avenues, which are at different heights. Since the indentation in each avenue can be configured in each avenue independently of the others, a • plurality of coding possibilities is achieved combinatorially.

In the connection plate 27 two pairs of pins 31, 32 and 31a, b; 32a, b, respectively, which are molded as turn pins and optionally determined two usable oscillation axes 33, 34, which are arranged symmetrically to an average avenue running through the central axis 6. Each of the axes of oscillation 33, 34 can be used in the same way to hang the pressurized gas bottle 5 in the support according to Figure 1 and 3 respectively and to balance it during the connection process around this axis, since the check valve 4 including the coding means 35 is invariable against a rotation of 180 °. This essentially facilitates the connection of the pressurized gas bottle 5. The valve itself inside the check valve 4 is formed by a valve seat 37, which can be closed by a valve seal 39 (Figure 5). (c)). The valve seal 39 is housed in the upper part of the valve body 40, which preferably has a rectangular cross section, so that during a simultaneous lateral conduction the gas transit is guaranteed without difficulties. The body of the valve 40 is transformed upwards into a pop-up valve rod 38, which makes it possible to actuate the valve from the connection opening 30. The pop-up valve rod 38 is hardened and is introduced from above reaching the area of the rope 29 conical With this, it is achieved that during a cut by accident of the check valve 4, the valve lifter rod 38 of the neck of the bottle is started, without losing the sealing function of the valve 37, 39, 40. The valve body is driven through an adapter piece 41: on the pressure of a spring 42, which rests on the blind hole of a filter housing 43 screwed from below. A sintered metal filter pattern 44 is preferably placed in the filter housing 43 and is secured by means of a locking screw 45. The check valve 4 has the structure shown in FIG. 7 in the assembled condition. opposite the check valve 4 in the connection system of Figure 1 and 2 forms the reducing valve 2 illustrated in greater detail in Figure 6 with the gas management head 52 screwed down. In the upper part of the reducing valve 2 a membrane 48 is housed, which separates the pressure chamber 50 from the environment; The diaphragm 48 is half-fitted on both sides with support rollers 47, 49. The upper support sheave 47 is compressed with the pressure of a spring 46, which can be adjusted by means of a hidden adjusting screw (no illustrated in Figure 6) under a lid cover 55. With the lower support sheave 49 the membrane is supported on the push rod 51, which runs down the central axis through the redoubt valve :: a 2 and the gas management head 52 screwed in and there it projects so that when connecting the check valve 4 it can operate on the lift-valve rod 38 in the manner described in the foregoing. The fit? The gas administration 52 is formed as an insertion cone 54 that sits in the opening cone, adapting in its upper area to the opening cone (30) and sealing when connecting the check valve 4 and the reducing valve :: a 2. The outer shapes 53 (Figure 6, 8), which surround the insertion cone 54, adapt to the interior shapes 35 and together form the coding means. Opposite the pressure gauge 8 of the reducing valve 2 is a gas administration connection 60 (which, for simplicity, only half is shown in the additional representation), which contains a line check valve 62 tensioned by means of a spring 61. Through the resistance of the valve of retention of the conduit 62 remains when emptying the bottle of gas under pressure a small residual pressure in the bottle, which is required by the manufacturer in many bottles. The check valve of the conduit 62 prevents backflow of gas, air or water to the bottle, so as to avoid impurities and corrosion (in the case of water) of the bottle respectively in a safe manner. The various phases of the connection process itself in a connection system according to the embodiment illustrated in Figure 1 are reproduced in Figure 9. First, the pressurized gas bottle 5 and the connection device 2, 3 are free of charge. mechanical coupling (Figure 9 (a)). The connection process starts, when the bottle 5 is suspended with a pair of pins 32 in the suspension openings 58 in the loading arms 12 of the wall support 3 (Figure 9 (b)). The bottle acquires in the suspended state a position of safe rest, in which the center of gravity of the bottle is leaded through the axis of rotation 34 in the pair of pins 32. The pressure gas bottle 5 and the The wall supports are mechanically coupled to each other in this manner and form an oscillation system with an oscillating axis 34. The pressurized gas bottle 5 can then be balanced by means of light pressure in the direction of the wall around the axis. of oscillation 34 so that the other pair of pins 31 achieves an interlocking fit with the connecting lever 14 (Figure 9 (c)). This is only possible, when the inner shape 35 and the outer shape 53 of the coding means match. The reducing valve 2 is mounted by means of a spring 59, preferably in the form of a set of disk springs, by pulling back on the support plate between the support arms 12. With the bottle finally suspended it is easily compressed this spring 59 against its previous tension (approximately 0.4 mm). This ensures that the gas management head 52 is compressed on the connection plate 27 instead of on the retaining surface. In case a wrongly coded bottle is hung, none of the connecting parts is damaged: since the outer shape 53 and the inner shape 35 do not fit, the spring 59 is compressed mainly more strongly (approximately 1.5 mm). The length of the push rod 51 no longer reaches there to operate the poppet valve 38 of the check valve. If the pressure of the bottle of a pressurized gas bottle 5 connected at the level of the pressure chamber 50 is reduced, the membrane 48 is compressed downwards by the spring 46. With this the push rod 51 is moved downwards. and completely open the check valve. As previously mentioned, a small residual pressure remains due to the check valve of the conduit 62 in the bottle. The bottle can now be unlocked to exchange it by means of a pressure in the '} twenty-one button ejn the connection lever 14. After unlocking it, it still hangs from the pair of straight pins 32 in the hook-shaped suspension opening 58 of the loading arms 12. It can then be removed without using force and exchanged for a full bottle. The assembly of the interior parts of the check valve and the gas management head 52 during the connection is reproduced for various phases of constriction in Figure 10. In Figure 10 (a) the bottle is hung (not shown). ) with the check valve in the holder that is balanced around the oscillation axis 34 to the left. Both the coding means 35, 53 as well as the connection opening 30 and the insertion cone 54 as well as the drive rod 51 and the valve lifter rod 38 are not yet in the grip. If the bottle is swung further to the left (Figure 10 (b)), the insertion cone 54 moves in the area of the O-ring 56 and seals the connection outwards, without the drive rod 51 pushing on the rod lift valve 38 and open the check valve. Only when the roll is made to the stop (Figure 10 (c)), the valve lever 38 is pushed down by means of the drive rod 51 and the valve in the bottle is opened.

Comparable connection processes are presented when the mobile support 20 is used instead of the wall support 3. When using the manual operating device 23, the non-return valve 4 is not automatically opened, but after the drive by the spindle 25 after the connection. In conjunction with the invention, a connection system is provided, which is highlighted by a plurality of settings: the system makes possible a rapid exchange of bottles without the use of tools, with the wall support a direct construction is possible in a device and a fastening of the pressurized gas cylinders respectively of up to approximately 15 kg directly to a wall, with the mobile support can be connected optionally free standing bottles, you can optionally operate wall brackets or movable supports with an integrated reduction valve as pre-regulated connections or without integrated reducing valve with existing pressure reducing valves, a duct check valve integrated in the gas management connection prevents the backflow of gas or liquids (for example of beverages in the preparation of drinks) and thus protects the bottle from impurities or corrosion, - the check valve of the duct prevents complete emptying of the bottle, the integrated coding means allow the use of a multiplicity (more than 126) codes, with the help of which different gaps can be filled and consumed interchangeably, - by means of coding connections can be made exclusive and avoid unauthorized gas administration and filling, - pressurized gas cylinders can be filled automatically by means of the integrated check valve, - a rupture safe prevents the gas from escaping, when the upper part of the valve Retention (the part that projects outside the neck of the bottle) is broken or torn off by falling.
