Definitions

  • the invention relates to a compressed gas source with fuel gas filling for manual handling.
  • the term "manual handling” means that the source of pressurized gas is enclosed with an attached gas burner by one hand and freehand over workpieces, e.g. be soldered or welded, can be performed. It is about a unity of container and content.
  • the fuel gases used develop in a burner under air high flame temperatures and are preferably intended for soldering or brazing.
  • Known gas sources have a multi-part metal container made of sheet steel with a joint seam, which follows a generatrix of the cylindrical bottle jacket, a likewise made of sheet steel arched bottom and a profiled upper part, in which a coaxial extraction valve is arranged. The bottom and top are connected by folds with the bottle jacket.
  • the filling of liquid gases consists for example of 40 vol .-% propane and 60 vol .-% butane.
  • Such gas sources generally do not meet the stringent requirements Test regulations of the competent authorities and also not the demand for the highest possible flame temperature.
  • cambered pressure vessel made of metal from an initially cup-shaped pot with a flange of sheets, which consist of an aluminum alloy, coated with plastic and are preferably provided for filling with a beer amount of 3 to 5 liters as beer kegs.
  • a punch of polyurethane rubber By a punch of polyurethane rubber, the pot in a two-part mold in a second operation both radially and axially further deformed and provided with profiles in the form of vertical ribs in the shell part and radial troughs in the bottom part.
  • the wall thickness should be between 0.3 and 1.0 mm before pressing and preferably 0.5 mm. nothing is disclosed about the compressive strength and the presence of official permits. At any rate, beer does not produce any pressures that could blow up such a container.
  • the EP 1 333 223 A1 calls fillings from refrigerants such as 14 kg of tetrafluoroethane and chlorodifluoromethane under an operating pressure of about 10 to 15 bar and with wall thicknesses of 4.7 to 5.2 mm. Training and production are similar to the DE 199 14 029 C2 , but with three-stage thermoforming process.
  • the temperature "T” is between 50 ° C and 55 ° C.
  • the vapor pressure of butane at 3.1 bar is given.
  • the process of tearing when exceeding the tensile stress The seam of the bottom rolls on or unrolls until the container bursts or the soil is blown off.
  • the US 3,024,936 shows for small gas bottles a way from the steel container to the aluminum container with a purity of 99%.
  • hydrocarbons such as propane, butane
  • fire-extinguishing gases such as carbon dioxide
  • aerosol sprays and carbonated soft drinks are initially called steel containers.
  • the following bursting pressures are rounded and converted into metric mass:
  • a bursting pressure of 35 bar is specified.
  • such containers are not suitable for hydrocarbons such as propane and butane because of bursting pressures between 35 and 70 bar.
  • a maximum operating pressure of 21 bar is specified, whereby a safety valve and a safety margin of 2 is specified for a pressure limit of 32 bar.
  • DE 73 40 580 U is a seamless, deep-drawn pressure vessel made of light metal, which is provided in the neck with an internal thread and should be used, for example, for hand-held fire extinguishers. Not disclosed are volume, operating and bursting pressures, fuel gas filling, bleed valves, and the ability to connect gas burners, which also precludes use for fire extinguishers.
  • the invention is therefore based on the object to provide a viable compromise between the bursting pressure of the metal container, the safety regulations, the flame temperature of the gas burner and the manufacturing costs in a manually operated and one-handed to be supplied gas source.
  • a viable compromise between the bursting pressure of the metal container, the safety regulations, the flame temperature of the gas burner and the production costs is surprisingly found in a manually operated and one-handed leading to pressurized gas source.
  • the bursting pressure is based on a function of the diameter and the wall thickness of the bottle jacket, the bottle construction and the material properties of the material.
  • the containers of such gas sources are also referred to as "monobloc containers".
  • the metal container 2 is designed for a filling volume of 1000 ml, a test pressure of 22 to 27 bar and a bursting pressure of at least 50 bar and was produced by extrusion of aluminum sheet with an aluminum content of 99.5%.
  • the outer diameter "Dz" is 80 mm and can therefore be covered by one hand.
  • a one-piece shell part was produced in a die by means of a punch (not shown here), which in the axial direction of a cylinder portion 3 with the height "hz" of 250 mm and a neck portion 4 with a height "hh” of 48 mm composed.
  • the thickness "db" of the bottom part 5 is 2.6 ⁇ 0.2 mm and its curvature “hb” upwards 12 mm.
  • the bottom part 5 is well rounded and seamless in the cylinder section 3 on.
  • the neck portion 4 was then made by deformation with a radius "R" of 65 mm, wherein the transition from the cylinder portion 3 was formed in the neck portion 4 stepless and kink-free.
  • the wall thickness "dw" of the cylinder portion 3 was 1.1 ⁇ 0.1 mm, but at least 0.6 mm.
  • a bead 6 was made with an outside diameter "Da” of 31.3 ⁇ 0.2 mm in a conventional manner by rolling to be able to put a gas burner, non-positively and / or positively.
  • a valve carrier not shown here is connected to a removal valve undetachably connected to the shell part. This valve can be opened by a plunger located on the gas burner or by an intermediate adapter with an analog plunger and automatically closes again when the gas burner and / or the adapter are removed.
  • the total height "H” at the end of the process was 250 mm.
  • the filling "F” consists of a liquid gas with a share between 60 and 95 wt .-% propene (formerly called propylene). This can be by means of an attached burner with air supply extremely high flame temperatures produce.
