Definitions

  • the invention relates to a protective device for pressurized gas bottles, with a protective device body which encloses an inner cavity for receiving a withdrawal valve and can be connected to a fastening section with the neck of a pressurized gas bottle and has at least one recess for operating the withdrawal valve.
  • pressurized gas cylinders which in the following is to be understood in particular to mean pressurized gas cylinders, gas cartridges or pressurized cans, is the extraction valve, which is used to remove gas and to fill the pressurized gas cylinder.
  • extraction valve here refers to the extraction valve including all fittings that may be integrated therein, such as pressure reducers, dosing and needle valves, or the like. Understood.
  • valve protection devices in the form of protective hoods, brackets or caps are used, which are attached to an existing thread on the neck of the compressed gas cylinder or to a corresponding fastening section of the extraction valve.
  • These protective devices have a high degree of rigidity, so that in the event of an external force acting against the protective device, for example when the cylinder falls over, the energy to be absorbed is diverted to the body of the pressurized gas cylinder and the extraction valve is thus protected from damage.
  • Protective devices that are made of metal and / or plastic are for example in the publications DE 44 40 298 A1 , U.S. 3,776,412 A , WO 91/04197 A1 , WO 98/23895 A1 , EP 0 725 247 B1 , EP 0 629 812 A1 , EP 0 939 875 A1 or the U.S. 4,332,331 A1 described.
  • Valve protection devices are also required by law for pressurized gas cylinders during transport and their design requirements are standardized in ISO 11117.
  • the execution requirements include, among other things, the performance of a drop test, the passing of which is a prerequisite for a use permit.
  • the protective devices are made of plastic at low cost.
  • pressurized gas cylinders whose volume is greater than 20 l and which can weigh from 40 kg to over 100 kg
  • the mechanical load on the protective device when the cylinder falls over can become so high that the stability of a plastic version is not sufficient to absorb the energy derive.
  • the protective device breaks and the extraction valve is damaged in an impermissible manner.
  • a metallic construction has predominantly been chosen for the protective device of heavy pressurized gas cylinders, which for example consist of aluminum or steel, with welded models as well as cast versions being available in the latter case.
  • the disadvantage here is that the metal versions are comparatively expensive compared to the plastic caps and also have a considerable weight of several kilograms, which makes the gas bottles difficult to handle.
  • FIG EP 1 041 339 B2 proposes to manufacture a protective device from two different materials, namely from an inner metal skeleton with high rigidity, around which an outer cap construction made of polymer material is injected.
  • this construction is very complex and expensive to manufacture.
  • the object of the present invention is therefore to develop an inexpensive protective device for pressurized gas cylinders which, particularly in the case of heavy containers, offers reliable protection of the extraction valve against impact when the pressurized gas cylinder falls over.
  • the protective device body is made of plastic and is equipped with at least one plastically or elastically deformable deformation zone for absorbing the impact energy in the event of an impact or if the pressurized gas container.
  • the protective device In contrast to the prior art, in which a protective device had to be as rigid as possible in order to direct the energy to be absorbed in the event of a fall or impact to less sensitive parts of the pressurized gas cylinder, the protective device according to the invention absorbs this energy to a large extent itself.
  • the protective device is equipped with deformation zones which are plastically or elastically deformable and which convert the kinetic energy supplied in the event of impact, fall or impact into potential energy (deformation energy).
  • the deformation zones are designed so that the fraction of the energy supplied to the protective device in a drop test in accordance with ISO 11117 that does not cause deformation of the deformation zones is so small that the stability of a plastic construction is sufficient to transfer this energy to the bottle body without the withdrawal valve is exposed to excessive impact or shock.
  • a protective device that is also suitable for heavy bottles with a total weight of 40 kg to over 100 kg exclusively from plastic. After deformation, e.g. if you fall, the protective device is replaced by a new one. Such falls only occur very rarely, so that the economy of the invention is not impaired.
  • the deformation zone of the protective device can be designed as a separate deformation body firmly connected to the protective device body, or it can be embodied in one piece with the protective device body.
  • the deformation zone and the protective device body can be manufactured independently of one another and in particular consist of different plastic materials.
  • the protective device body is designed to be deformable as a whole, in which case it must be ensured that it is in the Deformation of the protective device body does not result in an excessive force acting on the extraction valve.
  • deformation zones can be provided on a protective device, all of which are elastic, all plastic or partially elastic and partially plastic deformable.
  • the deformation can go as far as the destruction of the deformation zones at predetermined breaking points, which are of course designed or arranged in such a way that when they break the extraction valve - at least when a force is applied in accordance with the drop tests required in ISO 11117 - is not impermissibly damaged.
  • the deformation zone In the case of plastically deformable deformation zones in particular, it is advantageous to form the deformation zone from a material with a foam-like or honeycomb-like structure.
  • a honeycomb-like structure made of polymers is used, for example, in the WO 2013/117838 A1 described. Due to the foam or honeycomb-like structure, a great deal of energy can be absorbed and converted into internal energy, and the forces acting are at least to a large extent deflected in a direction within the protective device pointing away from the extraction valve.
  • the deformation zone is formed by cavities which are arranged inside the protective device body or on the protective device body and in which there is a plastically deformable mass, for example construction foam, which absorbs the energy absorbed in the event of its deformation.
  • a plastically deformable mass for example construction foam
  • the deformation zone comprises a deformation body in which an outer casing is filled with a foam-like or pourable or honeycomb-like material.
  • the cover ensures the external shape of the deformation body and protects the filling during normal operation.
  • the elastic deformation zone comprises spring elements which extend around the protective device body.
  • a particularly advantageous elastic deformation zone is constructed in the manner of a corrugated hose or pipe. Such a deformation zone has a high elasticity and a high resistance to impact by impact or impact.
  • a corrugated hose-like deformation zone is designed, for example, in such a way that it completely or partially encompasses the extraction valve.
  • Another advantageous embodiment provides several spring elements or corrugated hose-like deformation bodies which are arranged in the circumferential direction around the extraction valve and thereby form a cage-like structure by which it is protected from inadmissible impact.
  • the deformation zone comprises one or more buckling bars.
  • a significant part of the energy absorbed is used to bend the buckling bar or bars and ultimately to break them.
  • the pressurized gas cylinders in which the protective device according to the invention is used are preferably containers with a filling volume of at least 20 l, preferably 50 l.
  • these are pressurized gas cylinders in which technical or medical gases, in particular oxygen, nitrogen, carbon dioxide, noble gases or welding gas mixtures or food gas mixtures, are stored at a pressure of 150 bar, 200 bar or 300 bar.

  • the outer wall 15 of the protective device body 10 is designed in the manner of a spring, the protective device body 10 thus has an outer diameter which alternates in the axial direction. Due to the spring-like configuration of the outer wall 14, the protective device body 10 is elastic, that is to say it can react to an external impact by means of elastic deformation.
  • the protective device body 10 thus acts overall as a deformation zone in that it absorbs part of the impact energy and converts it into deformation energy and thereby protects the extraction valve.
