Definitions

  • the invention relates to a pressurized gas cylinder with a cylinder valve for filling and withdrawing gas and with a valve protection device to protect the cylinder valve from damage, the valve protection device comprising a housing mounted on a neck of the pressurized gas cylinder which is equipped with an access opening allowing access to the cylinder valve .
  • valve protection device is to be understood as a safety element mounted on a pressurized gas cylinder, which basically remains on the pressurized gas cylinder during the intended use of the pressurized gas cylinder, ie in particular also when gas is withdrawn.
  • valve protection devices are designed in such a way that, on the one hand, they ensure reliable protection of the cylinder valve from damage due to impact, fall or improper handling, etc., and, on the other hand, allow access to the cylinder valve and thus the removal of gas from the compressed gas cylinder without having to be removed beforehand .
  • valve protection devices are known; Conventional devices of this type have, for example, the shape of a half or full shell, a bracket or a cage and are usually made of metal, e.g.
  • Valve protection devices in the sense of this invention are therefore in particular not referred to as “protective cap” in the following, and are generally made of steel Safety elements that are only intended to protect the cylinder valve from damage during the transport of pressurized gas cylinders and that must be removed from the cylinder before it is used as intended, i.e. for the removal of gas or before the cylinder is filled.
  • cylinder valve (or “extraction valve”) is understood here to mean the cylinder valve used to extract gas and to fill the pressurized gas container, including any fittings integrated therein, such as pressure reducers, metering and needle valves, or the like;
  • pressurized gas cylinders is intended to subsume all types of containers intended for the storage of gas under pressure, in particular pressurized gas cylinders, gas cartridges or pressurized cans.
  • valve protection device for gas cylinders is in EP 0 629 812 A1 described.
  • This object is a plastic element with a lower part for fastening to the gas cylinder and an upper part for protecting the valve, the lower part comprising a lateral projection with a curvature as a suspension device.
  • the valve protection device can be adapted to compressed gas containers of different sizes and types, for example to compressed gas cylinders with a volume of 2, 5, 10 or 20 liters.
  • Further valve protection devices are, for example, in the publications EP 2 101 103 B1 , EP 0 939 875 A1 , DE 103 08 676 A1 , DE 101 46 261 A1 , DE 100 57 469 A1 or DE 199 26 961 A1 described.
  • the object of the present invention is therefore to develop a pressurized gas cylinder with a valve protection device which is equipped with a reliable and inexpensive tamper-evident mechanism.
  • the present invention therefore provides for a tamper-evident device adapted to the respective valve protection device to be integrated into the valve protection device, i.e. to provide means that allow the tamper-evident device to be attached to the valve protection device without great effort after the pressurized gas cylinder has been filled, and at the same time to reliably identify the tamper-evident status of the compressed gas cylinder enables.
  • the means required for this include, in particular, a securing element which, when installed, extends wholly or partially over the connecting piece and / or the handwheel in such a way that the connection of a gas line or a fitting to the connecting piece or the actuation of the handwheel is impossible or significant is made more difficult, and coordinated fastening elements on the securing element of the tamper-evident on the one hand and the housing of the Valve protection device, on the other hand, which ensure that the tamper-evident device is easy to attach and cannot be removed under normal conditions without the securing element and / or the fastening elements being irreversibly damaged or changed in such a way that the tamper-evident device cannot easily be restarted the valve protection device can be installed.
  • this is done by means of one or more predetermined breaking points on the securing element and / or the fastening elements, which break or break when the tamper-evident mechanism is removed.
  • the invention thus enables in particular the manufacture of valve protection devices with tamper-evident security in series production, which have a constant and thus previously determinable reliability with regard to the tamper-evident identification.
  • a preferred embodiment of the invention provides that the tamper-evident mechanism extends transversely or longitudinally over at least part of the access opening for the purpose of securing the cylinder valve with a securing element in such a way that the tamper-evident mechanism blocks access to the connecting piece and / or the handwheel of the cylinder valve and so that the removal of gas is prevented until the tamper-evident security is removed.
  • a securing element is thus conceivable which is fastened on one side to the access opening and protrudes into the access opening or extends over it.
  • a particularly advantageous embodiment provides that the securing element is connected to the housing of the valve protection device on at least two opposite sides of the access opening by means of connecting elements, with a predetermined breaking point being arranged on at least one connecting element. In the installed state, the securing element extends over the access opening in such a way that access to the connecting piece and / or the handwheel of the cylinder valve is blocked.
  • the securing element In order to rule out misuse as much as possible, the securing element should lead as close as possible to the connecting piece and / or the handwheel in the installed state, so that access is not easily achieved by bending the Securing element is possible, or at least such that bending away requires a force that exceeds the tensile strength of the predetermined breaking points.
  • the securing element is preferably made of a flexible material, in particular plastic, which enables the securing element to arch between the connecting elements via a handwheel and / or connecting piece in the installed state.
  • the securing element preferably comprises at least one connecting element with a holding section, the shape of which is adapted to a corresponding recess in the valve protection device.
  • the securing element preferably comprises at least one connecting element which, in the installed state, extends through a bore in the housing of the valve protection device and is equipped with a barb-like holding section.

  • the head section is pushed through the bore and is then connected to the securing section in the manner of a barbed hook via the neck section extending through the bore.
  • the neck section tears and the head section falls off; a reattachment of the securing element is then no longer easily possible.
  • the securing element is preferably at least partially elastic and is under tension when installed, i.e. it is held firmly on the housing of the valve protection element under the action of a force counteracting its deformation and at the same time in its position preventing access to the cylinder valve stabilized.
  • a particularly useful, easy to assemble and inexpensive securing element is a wire, a cord or a band, in particular a band made of plastic, rubber or a fabric material, which extends across the access opening in the installed state.
  • a molded part made of plastic that is at least partially adapted to the opening cross-section of the access opening of the valve protection device can be used.
  • Such a molded part can also be designed in such a way that it extends into the access opening with individual sections and in this way makes access to the cylinder valve difficult or impossible.
  • Such a comparatively large-area securing element also offers the advantage that a user can determine the originality of the pressurized gas cylinder even from a great distance. By coloring the securing element or applying a clearly visible marking to the securing element, this advantage can also be expressed even more strongly.
  • Another advantageous embodiment of the invention provides for double protection.
