Definitions
- the invention relates to a fitting for liquefied gas bottles and a method for refilling with liquefied gas.
- a gas cylinder is usually an existing pressure vessel for the transport and storage of pressurized gases, usually made of metal, usually steel.
- Such a bottle can have a volume of more than 100 liters.
- the nominal pressure can be several hundred bar.
- Gases such as LPG are in liquefied form in liquefied gas cylinders. Common gases are ethane, propane, butane and mixtures thereof. These gases can be liquefied at room temperature using comparatively low pressure.
- the liquid gas content of such bottles is usually between 3 and 33 kg.
- the height of such liquid gas bottles is usually between 420 mm and 1290 mm.
- the bottle diameter is typically between 200 mm and 318 mm.
- LPG bottles are sealed with a fitting, to which a suitable hose line can be screwed, usually in conjunction with a pressure reducer, for the controlled removal of their contents. Furthermore, there is a safety valve in the valve for LPG bottles, which limits the permissible overpressure in the bottle to, for example, approx. 30 bar to prevent bursting.
- a fitting of such a liquid gas bottle has a lateral connection piece as a gas tap, which is used on the one hand for filling and on the other hand for removal. Lines are manually screwed onto this gas tap both when it is removed and when it is refilled.
- the side connection piece When the gas tap is open, the side connection piece is connected in a gas-conducting manner to an opening on the underside of the fitting. This underside with the opening is located above the liquid level when a liquid gas bottle is set up. at when gas is withdrawn, the gas which is above the liquid level in the gaseous state is therefore removed
- Liquid gas bottles are used for the operation of gas consumers such as gas stoves, gas cookers, gas grills, gas heating ovens or gas radiant heaters. If the content of a liquefied gas bottle is used up, liquefied gas bottles are returned by the consumer to the point of sale of liquefied gas bottles for refilling. After such a return of a liquid gas bottle, it is transported from the point of sale to a central filling system or filling station.
- a fitting is known from the publication EP 3021034 A1, which has a gas tap for gas extraction and an opening for refilling a liquid gas bottle.
- the opening for refilling a liquid gas bottle can be connected in a gas-conducting manner by opening a valve with a hose-shaped or tubular line of the fitting, which should extend at least 300 mm, preferably at least 400 mm, into a liquid gas bottle when the fitting is connected to such a gas bottle.
- the result of this is that the line can extend into the liquefied part of the gas, which above all enables very rapid emptying by pumping out
- the fitting according to the invention for a liquefied gas bottle comprises a gas consumer connecting piece.
- a gas consumer can be connected to the gas consumer connecting piece in order to supply the gas consumer with gas.
- the gas consumer connection piece has in particular a thread through which a gas consumer can be connected using a screw connection.
- the gas consumer connection piece protrudes in particular from the side of the fitting.
- gas inlet opening on the underside of the fitting and a gas-conducting connection between the gas inlet opening and the gas consumer connection piece.
- Gas from a gas bottle connected to the fitting can reach the gas consumer connection port via the gas inlet opening in order to be able to supply gas to a gas consumer in this way.
- the fitting includes a turning handle that can be turned into an open position and a closed position. In an open position, gas can flow from the gas inlet opening to the gas consumer connecting piece. In the closed position, no gas can flow from the gas inlet opening to the gas consumer connecting piece.
- the top of the fitting has a closable opening for refilling.
- a closable opening means that there is an opening and also a closing device which, when closed, prevents gas from flowing through this opening into a gas bottle connected to the fitting.
- the closable opening is closed in particular by a valve which is actuated from the outside in this way that the valve opens. In particular, the valve can be opened by pressure.
- the rotary handle has the closable opening through which a gas bottle can be refilled.
- the edge of the closable opening also called the opening edge, is therefore part of the rotary handle.
- the opening in particular enables automated refilling by means of a filling station, as is described in the document EP 3 021 033 A1.
- the number of parts required is small, especially in comparison to the prior art known from the document DE 43 34 182 A1 and the document EP 3 021 034 A1, according to which an independent component for providing an opening on the top is provided.
- the construction space can be kept small.
- the lockable opening provided for refilling is located on the top of the fitting.
- the effort for positioning a gas bottle in the filling station is thereby kept low.
- a filling station can not only refill a gas bottle connected to the fitting from above with little centering effort, but also automatically open and close the twist grip from above, without additional effort for it positioning of a gas bottle is required.
- Such a valve can also be built with less technical effort compared to the valve known from EP 3 021 034 A1. Nevertheless, on technical if necessary, the rotary handle can be closed automatically when a gas bottle is to be refilled.
- the twist grip advantageously comprises an inner cylinder which forms an upper section of the gas-conducting connection which connects the closable opening on the top with the opening on the bottom. This helps to be able to manufacture the valve with a small number of components and with a small installation space.
- the rotary handle in particular comprises a cap which is connected in one piece to the cylinder.
- the twist grip can be made of metal, with the cap and cylinder being made in one piece by machining a metal block.
- the twist grip is then not composed of several parts that were initially manufactured individually. This also advantageously reduces the number of parts that are required for production.
- a locking device with which the closable opening can be closed.
- the closing device is formed in particular by a valve which can be moved from the outside by pressure against the force of a spring, as a result of which the opening opens. This makes automated refilling easier.
- the lower end of the valve is supported in particular against the housing of the valve.
- the upper end of the valve is connected, for example, in a clamped manner to the closing device or the valve of the closing device.
- Part of the locking device extends, for example, into a then spiral spring, which is held, for example, in a form-fitting and / or clamping manner by the upper region of the spring.
- the inner cylinder separates an inner channel from an outer channel in a gas-tight manner when the rotary handle is in its closed position. Gas can flow from the inner channel into the outer channel when the twist grip is in its open position. Gas can then pass along the gas inlet opening on the underside of a gas supply channel flowing into the inner channel. Gas can also flow from the outer channel to the gas consumer connecting piece. This configuration contributes to the fact that the valve can be manufactured with a small number of components with a small installation space.
- the inner channel and the outer channel preferably run in a ring around the gas-conducting connection which connects the closable opening on the top with the opening on the bottom.
- the available space is used particularly well to bring gas from a connected bottle to a consumer.
- the outer channel and inner channel are in particular on the same level.
- the inner channel is preferably located within the outer channel.
- Stroke movements of the inner cylinder are preferred by a rod, a bolt or a locking ring that extends into a recess.
- the recess is wider than the rod, bolt or locking ring, so that the rod, bolt or locking ring can be moved along the recess.
- the rod, bolt or locking ring can be made of metal or plastic.
- the retaining ring can be a sealing ring, which advantageously ensures improved gas-tight connections which can prevent an unscheduled escape of gas.
- the gas supply channel is preferably provided with a pressure relief valve, through which gas can escape from the fitting when the gas pressure is excessively high. A connected gas bottle is protected against excessive pressure.
- the pressure relief valve is preferably arranged on one side of the fitting, which is opposite the gas consumer connecting piece. This Arrangement helps that the valve can be made compact with little space.
- a riser pipe connection protrudes advantageously from the bottom. Gas can flow to the closable opening through the riser pipe connection.
- a riser pipe or a hose can be attached to the riser pipe connection in a simple manner. It is thus possible to select a riser pipe or a hose that extends to the bottom of a connected gas bottle. This makes it easier and faster to empty a gas bottle as part of an automatic refill.
- An interior, in which an external filling safety device is present, preferably borders on the underside.
- the external filling safeguard preferably runs at least partially obliquely within the interior.
- the external filling protection prevents the gas bottle from being filled by the gas consumer - connecting piece It works like a check valve. Gas can flow from the interior to the gas consumer connector when the twist grip is open.
- One or more sealing rings are advantageously present between the inner cylinder and the housing of the fitting adjoining the inner cylinder on the inside and / or outside and are held, for example, in recesses.
- the one or more sealing rings are pressed gas-tight against the inner cylinder.
- the sealing rings consist in particular of an elastomer or another flexible plastic.
- the valve body is preferably made of metal. A sufficiently stable valve body can be manufactured with little technical effort.
- the valve body is preferably in one piece.
- the number of components can be kept as low as possible. Also, the manufacturing effort is small because of it it is not necessary to first manufacture several parts individually and then to assemble them into the valve body.
- the valve body can instead be machined from a block, for example by milling and / or drilling. Such a one-piece production also avoids tightness problems.
- the twist grip is rotatably connected to the fitting housing in particular by means of a threaded connection.
- a lower section of the gas-conducting connection which connects the closable opening at the top with the opening at the bottom, is formed by the fitting housing. This also contributes to the valve being able to be made from a few parts.
- the fitting housing preferably includes the underside so as to further reduce the number of parts required.
- the gas consumer connection piece, the overpressure valve connection piece and / or the riser pipe connection piece are preferably also part of the fitting housing in order to keep the number of parts low.
- the rotary handle preferably comprises a cap with a funnel-like depression.
- the closable opening is in the bottom of the trough. This facilitates automatic refilling of a gas bottle.
- the trough is formed in particular by webs which extend from an edge of the cap in the direction of the closable opening. A distance remains between the webs into which a tool can extend. This facilitates automated actuation of the rotary handle.
- the webs are also advantageously integrally connected to the cap. The cap was then carved out of one piece in order to further reduce the number of parts.

- FIG. 1 Side view of the valve
- Figure 4 Sectional view through a further embodiment of a
- Figure 5 Section through a gas supply channel.
- FIG. 1 shows a sectional illustration of a fitting 1 for a gas bottle.
- the fitting 1 has a gas consumer connecting piece 2 of a conventional type.
- the gas consumer connecting piece 2 is provided with a thread 3.
- a gas consumer such as a gas burner or a gas heater can be connected to the gas consumer connecting piece 2.
- gas can be routed to the gas consumer from a gas bottle connected to the fitting 1 via the gas consumer connecting piece 2.
- the fitting 1 On the top of the fitting 1 there is a turning handle in the form of a rotatable handwheel 4.
- the fitting 1 can be opened or closed by turning the handwheel 4 on or off about the axis 5. If the fitting 1 is open, gas can flow from a gas bottle connected to the fitting 1 through one or more gas inlet openings 6 on the bottom 7 to a gas consumer connected to the gas consumer connection piece 2. If the fitting 1 is closed, then no gas can flow from a gas bottle connected to the fitting 1 through the fitting 1 to a gas consumer connected to the gas consumer connecting piece 2.
- the component 8 is a circumferential sealing body, which preferably consists of a There is elastomer.
- the circumferential sealing body 8 is held in a form-fitting manner by a mandrel of the component 9, for example made of metal.
- the component 9 is part of the closure and is therefore also called the closure body 9.
- the circumferential sealing body 8 also lies with its underside on the component 9.
- the component 9 also extends into the spiral spring 10 and is thereby held by the spring 10 in a clamping manner.
- the opening is thereby opened.
- This opening is connected to a riser pipe connector 12 on the underside in a gas-conducting manner through a filling channel 13, 14.
- the filling channel comprises an upper section 13, which is widened compared to a lower section 14.
- the prestressed spring 10 is located in the widened section 13 of the filling channel.
- the lower end of the spring 10 is supported by the bottom of the section 13.
- the upper end of the spring 10 is supported against widening of the component 9.
- Gas can flow through the opening edge 11 in the direction of the ascending pipe connection piece 12 and out of the ascending pipe connection piece 12 when the closure 8, 9 has been pressed down into an open position. Conversely, gas can then also be pumped out of a gas bottle connected to the fitting 1 through the riser pipe connection 12 when the closure 8, 9 is open. Gas can therefore be pumped out in the open state of the closure 8, 9 via the opening located on the top of the fitting 1 in order to empty a gas bottle connected to the fitting 1.
- the riser pipe connection piece 12 is designed and set up to be able to connect a riser pipe or a hose that extends to the bottom of a connected gas bottle. Opposite the gas inlet - bottom 7, the riser pipe connector 12 protrudes downward. So that a riser pipe or a hose can be reliably connected to the riser pipe connection piece 12, the outer circumference of the Riser pipe connection piece 12 has a bulge 15 which surrounds the riser pipe connection piece 12 in an annular manner and which is partially circular in section.
- the fitting 1 has an annular inner channel 17, through which gas can flow from a gas supply channel 18 on the right-hand side to the gas consumer connector on the left when the handwheel 4 is turned is in an open position.
- gas supply channel 18 leads from the one or more gas inlet openings 6 to the area of the ring-shaped inner channel 17 on the right.
- An ring-shaped outer channel 19 runs parallel to the ring-shaped inner channel 17, specifically around the ring-shaped inner channel 17.
- the annular outer channel 19 is separated from the annular inner channel 17 by an annular wall 20.
- the annular wall 20 therefore forms the outer wall of the annular inner channel 17 and also the inner wall of the annular outer channel 19.
- the annular outer channel 19 is connected in a gas-conducting manner to the gas consumer connecting piece 2, so that gas from the annular outer channel 19 is passed through the gas consumer - Connection piece 2 can flow through and then on to a gas consumer connected to gas connection piece 2.
- a sealing ring 21 with a flat underside is located in a recess on the underside of the handwheel 4. If the handwheel 4 is in its closed position, as shown in FIG. 1, the flat underside of the sealing ring 21 lies gas-tight on the top of the annular wall 20.
- the top of the annular wall 20 is rounded in order to reliably enable a gas-tight connection. Because the sealing ring 21 has a flat underside and the top of the annular wall 20 is rounded, the thickness of the annular wall 20 can advantageously be small. Advantages of installation space can be achieved in this way. Gas cannot pass from the annular inner channel 17 into the annular outer channel 19 if the underside of the sealing ring 21 lies gas-tight on the top of the annular wall 20. It is thereby prevented that, when the handwheel 4 is closed, gas can flow from a gas bottle connected to the fitting 1 to the gas consumer connecting piece 2.
- the sealing ring 21 is thereby lifted off the annular wall 20, that is to say it is moved upward. Gas can then flow from the annular inner channel 17 into the annular outer channel 19 and from here further into the gas consumer connecting piece 2.
- the handwheel 4 is sealed in a gas-tight manner by one or preferably a plurality of additional sealing rings 22, preferably with a round cross section, such that gas cannot emerge from the ring-shaped outer channel 19 upward out of the fitting.
- additional sealing rings 22 are preferred since no gas should escape unplanned in order to avoid unplanned emptying of a gas bottle.
- the handwheel 4 is sealed gas-tight by an inner sealing ring 23, preferably with a round cross-section, in such a way that gas cannot flow upward from the annular inner channel 17 into the upper section 13 of the filling channel.
- a sealing ring 23 is sufficient, since it is undesirable that gas can flow into the filling channel because of a leaking sealing ring 23, but this means that a gas bottle cannot be emptied unscheduled.
- the handwheel 4 comprises an inner cylinder 24, which has an external thread 25 in an upper region.
- the aforementioned sealing rings 22 and 23 adjoin this inner cylinder 24 in a gas-tight manner on the inside and outside.
- the inner cylinder 24 has, for example, one or more circumferential recesses on its outside, in which one or more sealing rings 22 are held.
- the external thread 25 of the inner cylinder 24 is screwed into an internal thread 26 of a fitting housing 27.
- a retaining ring 28 is held, which extends inwards into a recess 29.
- the recess 29 is provided all around on the outer circumference of the inner cylinder 24.
- the recess 29 is wider than the width of the locking ring 28, so that the locking ring 28 can be moved along the width of the recess 29 in the form of a relative movement. This limits movement of the handwheel 4 both in the direction of the closed position and in the direction of the open position. The locking ring thus prevents the valve 1 from being screwed apart. The way to open the valve is limited.
- the fitting housing 27 is made in one piece from metal and is worked out from a metal block, for example by drilling and milling.
- the valve body consists of one piece. Thus, several parts were not first manufactured, which were then joined together in such a way that they form the valve housing 27.
- the lower section 14 of the gas-conducting connection 13, 14, which connects the closable opening at the top with the opening at the bottom 7, is formed by the fitting housing 27.
- the fitting housing 27 thus comprises a tube which forms the lower section 14.
- the fitting housing 27 includes the bottom 7 of the fitting.
- the gas consumer connector 2, the upper pressure valve connector 16 and the riser connector 12 are also part of the valve body 27.
- the valve which opens at an excessively high overpressure.
- the valve comprises a circular valve seal 30, which is held by a valve cover 31.
- the circular valve seal 30 can be made of an elastomer in order to achieve a good sealing effect.
- the valve cover 31 is pressed by a preloaded valve spring 32 in the direction of an annular opening edge 33.
- the opening with the annular opening edge 33 is through the valve seal 30 is closed gas-tight if there is no excessive pressure. If the top pressure is excessively high, the valve cover 31 is lifted together with the valve seal 30 from the opening edge 32 in such a way that gas can escape to the outside.
- the outer end of the valve spring 32 is held by a cover 35 provided with recesses 34.
- the cover 35 is attached to the overpressure valve stub 18, for example by a screw connection.
- the cover 35 has cutouts 34 so that gas can escape through the cover 35 in the event of an excessively high excess pressure.
- the inner cylinder 24 of the handwheel 4 opens into a cap 38 at the top.
- the cap 36 has on its upper side a trough formed by webs 37 in order to make it easier for a tool to be able to automatically open or close the handwheel 4.
- automated refilling is facilitated, since a filling head of a filling station can be more easily connected to the valve.
- An inner space 38 borders on the underside 7 and is guided around the lower section 18 of the filling channel.
- the external filling protection 39 prevents the gas bottle from being filled by the gas consumer - connecting piece 2.
- the external filling protection 39 functions like a check valve.
- FIG. 2 shows a section through the fitting 1, which is rotated by 90 ° about the axis 5 in comparison to FIG.

- the cap-like end piece 52 preferably has a cylindrical jacket surface, at least in sections, in order to be able to be guided particularly reliably.
- the cap-like end piece 52 preferably has an opening 54 on the upper end face. As shown in FIG. 4, the diameter of the opening 54 is preferably smaller than the inside diameter of the lateral surface. A wall section against which the spring 10 can be supported is then available on the end face at the edge region. The opposite end face of the cap-like end piece 52 preferably has no such wall section, so that the spring 10 can be inserted into the cap-like end piece 52 unhindered. The outer diameter of the spring 10 then preferably corresponds to the inner diameter of the cap-like end piece 52, as shown in FIG. 4.
- the upper end face of the cap-like end piece 52 can also comprise, for example, a grid, against which the spring 10 can be supported.
- the upper and lower end faces of the cap-like end piece 52 are preferably gas-permeable so that gas can flow through the cap-like end piece 52. In the case of pumping, gas then flows through the cap-like end piece 52 and subsequently, for example through the openings between the webs 53 when the handwheel is open.
- the outer circumference of the cap-like end piece 52 preferably adjoins the inner wall of the filling channel 13, 14 in the region of its upper section 13, as a result of which the closure body 9 can be guided alternatively or additionally.

- the riser pipe connection piece 12 is in particular made in one piece and is preferably made of metal.
- the lower edge of the cap-like end piece 52 preferably rests on an upper edge of the riser pipe connection piece 12.
- the riser pipe connection piece 12 thus serves as a stop in order to limit the movement of the closure 8, 9 into the fitting 1.
- the length of the cap-like end piece 52 is then selected in this embodiment such that the spring 10 can be accommodated completely in the interior of the cap-like end piece 52. The spring 10 is thus particularly reliably protected against mechanical damage.
- the riser pipe connection piece 12 is preferably connected to the inner cylinder 24 of the handwheel 4 by a threaded connection 55.
- the riser pipe connection piece 12 then has, for example, an external thread which is screwed into an internal thread of the inner cylinder 24.
- the riser pipe connection piece 12 can, however, also be connected in a different manner to the inner cylinder 24 in a positive, non-positive and / or integral manner.

Gas can flow from the outer duct 19 to the gas consumer connecting piece 2 and into the duct 41. The gas consumer connecting piece 2 therefore preferably adjoins the outer channel 19 in order to be able to keep the installation space and the material expenditure small.
- FIG. 4 shows the closed position of the handwheel 4. No gas can then flow from the gas supply channel 18 into the outer channel 19. This is prevented by a sealing ring 21 which is pressed gas-tight from above against an annular wall 20 by the inner cylinder 24. The annular wall 20 separates the outer channel 19 from the gas supply channel 18.
- the sealing ring 21 is preferably located in an annular, step-shaped recess 58 on the underside of the inner cylinder 24.
- the annular seal 58 is held captively by the riser pipe connection piece 12.
- the riser pipe connection has, for example, a circumferential flange 59 which bears against the annular seal 21.
- the riser pipe connection 12 preferably has a recess 60 in which a further sealing ring 61 is held.
- This further sealing ring 61 improves the fact that the inner cylinder 24 is connected in a gas-tight manner to the riser pipe connection piece 12 with little technical effort in order to obtain a gas-tight filling channel 13, 14.
- the two sealing rings 21 and 61 lie against each other in a gas-tight manner.
- the sealing rings 21 61 can advantageously have different cross sections.
- one sealing ring 21 expediently has a rectangular cross section and the other further sealing ring 61 has a round cross section. Both sealing rings 21, 61 are held captively by the inner cylinder 24 and the riser pipe connection piece 12.
- a one-piece sealing ring can also be provided, which can also be made in one piece. For manufacturing and geometry reasons, however, it can be advantageous to provide two sealing rings 20, 61.
- the one or more sealing rings 20, 61 are preferably first inserted into recesses 58, 60 provided for this purpose, before the handwheel 4 is connected to the riser pipe connection piece 12. If the handwheel 4 has been connected to the riser pipe connection piece 12, the handwheel 4 can be screwed into the fitting housing 27 if further sealing rings 22 may be necessary beforehand for operation have been attached to the inner cylinder 24 of the handwheel 4 as intended.
- the annular wall 20 of the outer channel 19 is preferably part of the housing 27 of the fitting 1.
- the housing 27 of the fitting 1 is in particular in one piece. In this case, the annular wall 20 is then also connected in one piece to the remaining part of the valve housing 27.
- the gas feed channel 18 is preferably ring-shaped in section in order to keep installation space, material expenditure and the flow resistance for gas low.
- the gas supply channel 18 is located between an inner wall 88 which is annular in section and an outer wall 89 which is annular in section.
- The, for example, cylindrical inner wall of the gas supply duct 18 is then preferably formed by the riser pipe connection piece 12.
- the outer wall of the gas supply duct 18 is then preferably part of the fitting housing 27.
- the gas supply duct 18 can thus be formed by the fitting housing 27 and the riser pipe connection piece 12 with little installation space and little material expenditure.
- a valve body 81 which comprises an elastic membrane 62, is screwed into the pressure relief valve connector 18.
- the membrane 62 closes an opening 83 leading into the pressure relief valve connector 16.
- the membrane 82 is lifted off the opening 63 and gas can escape to the outside.
- the interior of the pressure relief valve connector 16 is protected against contamination by the membrane 62.
- the valve spring 32 of the valve with the circular valve seal 30 is held by the valve body 81 so that the spring 32 presses the valve cover together with the circular valve seal 30 against the opening edge 33 in a gas-tight manner.
- the pressure relief valve connector 16 thus comprises two valves that open when the internal pressure is too high. The attachment of the valves in the pressure relief valve connector 16 can take place regardless of whether the handwheel has already been installed or not
- the fitting 1 is screwed to the opening of a gas bottle with the aid of an external thread 64.
- the end face of the gas consumer connecting piece 2 can have an annular recess in which an annular seal 65 is inserted.
- the ring seal 65 enables a gas consumer to be connected in a particularly reliable gas-tight manner.
- a fuse can be provided which prevents the handwheel from being completely unscrewed unscheduled.
- the inner cylinder 24 can have, for example, a circumferential recess 66 on its outside, which can be part of the fuse.
- a bolt 67 can extend into this recess 66 in such a way that an unscheduled complete unscrewing of the handwheel 4 is prevented.
- the bolt 67 can be part of a screw which is passed through the fitting housing 27 and which can be reached from the outside for the purpose of assembly and disassembly.
- the embodiment shown in FIG. 4 can be manufactured and assembled with particularly little effort. The space required can still be kept small.
