Definitions

  • the invention relates to a fitting for liquid gas cylinders and a method for refilling with liquid gas.
  • a gas cylinder is a pressure vessel, usually made of metal, usually steel, for the transport and storage of pressurized gases.
  • a pressure vessel usually made of metal, usually steel, for the transport and storage of pressurized gases.
  • Such a bottle can have a volume of more than 100 liters.
  • the nominal pressure can be several hundred bar.
  • Liquefied gas bottles contain gases such as LPG in liquefied form. Common gases are ethane, propane, butane and mixtures thereof. These gases can be liquefied at room temperature by means of a 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.
  • Liquid gas bottles are closed with a fitting to which a suitable hose line can be screwed on, usually in connection with a pressure reducer, for the controlled extraction of their contents. Furthermore, there is a safety valve in the fitting of liquid gas bottles, which limits the permissible overpressure in the bottle to, for example, approx. 30 bar in order 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 withdrawal. Lines are manually screwed onto this gas tap both in the case of removal and in the case of refilling.
  • the side connection piece When the gas tap is open, the side connection piece is connected to an opening on the underside of the fitting to conduct gas. This underside with the opening is located above the liquid level in the erected state of a liquid gas bottle. At therefore, when gas is withdrawn, the gas which is in the gaseous state above the liquid level is withdrawn.
  • Liquid gas bottles are used to operate gas consumers such as gas stoves, gas stoves, gas grills, gas stoves or gas heaters. If the contents of a liquid gas bottle are used up, the consumer returns the liquid gas bottles to the point of sale of liquid gas bottles for the purpose of refilling them again. After such a return of a liquefied gas bottle, it is transported from the point of sale to a central filling plant or filling station.
  • a fitting 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 if the fitting is connected to such a gas bottle. This ensures that the line can reach into the liquefied part of the gas, which above all enables very rapid emptying by pumping out.
  • a valve includes the features of the first claim.
  • Advantageous refinements result from the dependent claims.
  • the fitting according to the invention for a liquid gas cylinder comprises a gas consumer connection piece.
  • a gas consumer can be connected to the gas consumer connection piece in order to supply the gas consumer with gas.
  • the gas consumer connection piece in particular has a thread through which a gas consumer can be connected using a screw connection.
  • the gas consumer connection piece protrudes laterally from 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 cylinder connected to the fitting can reach the gas consumer connection piece via the gas inlet opening in order to be able to supply gas to a gas consumer in this way.
  • the fitting comprises a rotary handle that can be turned into an open position and into a closed position. In an open position, gas can flow from the gas inlet opening to the gas consumer connection piece. In the closed position, no gas can flow from the gas inlet opening to the gas consumer connection piece.
  • the fitting has a closable opening for refilling on its upper side.
  • Closable opening means that there is an opening and also a closing device which, in the closed state, 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 can be that the valve opens. In particular, the valve can be opened by pressure.
  • the rotary handle has the closable opening through which a gas cylinder can be refilled.
  • the edge of the closable opening also called the opening edge, is therefore part of the rotary handle.
  • the opening enables automated refilling by means of a filling station, such as the one in the publication EP 3 021 033 A1 is described.
  • the number of parts required is small, especially in comparison to that from the publication DE 43 34 182 A1 and the pamphlet EP 3 021 034 A1 known prior art, according to which an independent component is provided for providing an opening on the top.
  • the installation space can be kept small.
  • the closable opening provided for this purpose is located on the upper side of the fitting for refilling. In particular, this keeps the effort for positioning a gas cylinder in the filling station low. If the rotary handle is now also on the top, then 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 rotary handle from above without additional effort for positioning of a gas cylinder is required.
  • Such a fitting can also be technically less complex than that from the EP 3 021 034 A1 known valve are built. Still, technically easy way the twist grip can be closed automatically if necessary when a gas bottle is to be refilled.
  • the rotary handle advantageously comprises an inner cylinder which forms an upper section of the gas-conducting connection which connects the closable opening on the upper side with the opening on the lower side. This helps to be able to manufacture the valve with a small number of components and with little installation space.
  • the rotary handle comprises a cap which is integrally connected to the cylinder.
  • the rotary handle can be made of metal, the cap and cylinder having been manufactured in one piece by machining a metal block.
  • the rotary handle 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 closing device with which the closable opening can be closed.
  • the closing device is in particular formed by a valve which can be moved from the outside by pressure against the force of a spring, whereby the opening opens. This makes automated refilling easier.
  • the lower end of the valve is supported in particular against the housing of the fitting.
  • the upper end of the valve is, for example, clampingly connected to the closing device or the valve of the closing device.
  • a part of the closing device extends, for example, into a then spiral-shaped spring which is held in a form-fitting and / or clamping manner by the upper region of the spring, for example.
  • 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 flow along from the gas inlet opening on the underside of a gas supply channel flow into the inner channel. Gas can also flow from the external duct to the gas consumer connection piece. This configuration contributes to the fact that the valve can be manufactured with a small number of components with little 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 upper side with the opening on the lower side.
  • the available installation space is used particularly well in order to be able to bring gas from a connected cylinder to a consumer.
  • the outer channel and inner channel are in particular in the same plane.
  • the inner channel is preferably located within the outer channel.
  • Stroke movements of the inner cylinder are preferably made by a rod, a bolt or a locking ring that extends into a recess.
  • the recess is so wider than the rod, bolt or locking ring 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 locking ring can be a sealing ring, as a result of which desired gas-tight connections which can prevent an unplanned escape of gas are advantageously ensured in an improved manner.
  • the gas supply channel is preferably provided with a pressure relief valve, through which gas can escape from the fitting in the event of an excessively high gas pressure. A connected gas cylinder is thus protected from excessive overpressure.
  • the pressure relief valve is preferably arranged on one side of the fitting which is opposite the gas consumer connection piece. These The arrangement contributes to the fact that the valve can be manufactured compactly with little installation space.
  • a riser connection piece advantageously protrudes from the underside. Gas can flow through the riser pipe connector to the closable opening.
  • a riser pipe or a hose can be attached to the riser pipe connection piece 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 cylinder. This makes it easier and faster to empty a gas cylinder during an automatic refilling process.
  • An interior space in which an external filling safeguard is present preferably adjoins the underside.
  • the external filling protection preferably runs at least partially obliquely within the interior.
  • the external filling protection prevents the gas cylinder from being filled by the gas consumer - the connection piece works like a non-return valve. Gas can flow from the interior to the gas consumer connection piece when the twist grip is open.
  • sealing rings which, for example, are held 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 fitting housing is preferably made of metal. A sufficiently stable fitting housing can be manufactured with little technical effort.
  • the fitting housing is preferably in one piece.
  • the number of components can thus be kept low. Also, the effort for production is low because it it is not necessary to first manufacture several parts individually and then assemble them to form the valve body.
  • the fitting housing can instead be machined from a block, for example by milling and / or drilling. Such a one-piece production also avoids sealing problems.
  • the rotary handle is rotatably connected to the fitting housing in particular by 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 fact that the fitting can be manufactured from a few parts.
  • the fitting housing preferably comprises the underside in order 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 makes it easier to automatically refill a gas cylinder.
  • 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 reach. This facilitates automated actuation of the rotary handle.
  • the webs are also advantageously connected in one piece to the cap. The cap was then machined from one piece in order to further reduce the number of parts.
  • the Figure 1 shows a sectional view of a fitting 1 for a gas cylinder.
  • the fitting 1 has a gas consumer connection piece 2 of conventional design.
  • the gas consumer connection 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 connection piece 2.
  • gas can be fed to the gas consumer from a gas cylinder connected to the fitting 1 via the gas consumer connection piece 2.
  • a rotary handle in the form of a rotatable handwheel 4 is located on the top of the fitting 1.
  • the fitting 1 can be opened or closed by opening or closing the handwheel 4 around the axis 5. If the fitting 1 is open, gas can flow from a gas cylinder connected to the fitting 1 through one or more gas inlet openings 6 on the underside 7 to a gas consumer connected to the gas consumer connector 2. If the fitting 1 is closed, then no gas can flow from a gas cylinder connected to the fitting 1 through the fitting 1 to a gas consumer connected to the gas consumer connector 2.
  • the component 8 is a circumferential sealing body, which preferably consists of an elastomer.
  • the circumferential sealing body 8 is held in a form-fitting manner by a mandrel of the component 9, which is made for example of metal.
  • the circumferential sealing body 8 is also with its underside on the Component 9 on.
  • the component 9 also extends into the spiral spring 10 and is thereby held in a clamping manner by the spring 10.
  • the opening is opened as a result.
  • This opening is connected in a gas-conducting manner through a filling channel 13, 14 to a riser connection piece 12 present on the underside.
  • the filling channel comprises an upper section 13 which is wider than a lower section 14.
  • the pretensioned 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 a widening of the component 9.
  • Gas can flow through the opening edge 11, specifically in the direction of the riser connection stub 12 and out of the riser connection stub 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 cylinder connected to the fitting 1 through the riser connection stub 12 when the closure 8, 9 is open. In the open state of the closure 8, 9, gas can therefore be pumped out 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 intended and set up to be able to connect a riser pipe or a hose that extends to the bottom of a connected gas cylinder. Opposite the gas inlet - underside 7, the riser connection piece 12 protrudes downwards. So that a riser pipe or a hose can be reliably connected to the riser pipe connector 12, the outer circumference of the riser connector connector 12 has a bulge 15 that runs around the riser connector connector 12 and is partially circular in section.

  • the ring-shaped outer channel 19 is connected to the gas consumer connection piece 2 in a gas-conducting manner, so that gas from the ring-shaped outer channel 19 through the gas consumer - Connection piece 2 can flow through and then on to a gas consumer connected to the gas consumer - connection piece 2.
  • a sealing ring 21 with a flat bottom is located in a recess on the underside of the handwheel 4. If the handwheel 4 is as in the Figure 1 shown in its closed position, the flat underside of the sealing ring 21 rests gas-tight on the upper side 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 bottom and the top of the annular wall 20 is rounded, the thickness of the annular wall 20 can advantageously be small. Installation space advantages can be achieved in this way.
  • the handwheel 4 is sealed gas-tight by one or preferably more external sealing rings 22 with a preferably round cross-section so that gas cannot escape from the annular outer channel 19 upwards out of the fitting.

  • the recess 29 is provided circumferentially on the outer circumference of the inner cylinder 24.
  • the recess 29 is wider than the width of the securing ring 28, so that the securing ring 28 is along the width of the recess 29 can be moved in the form of a relative movement. This limits a 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 screwing apart. The way to open the valve is limited.
  • the fitting housing 27 is made in one piece from metal and worked out of a metal block, for example by drilling and milling.
