Definitions

  • the invention relates to a device for protecting the gas bottle valve of steel bottles, which have a threaded neck ring for screwing on the protective device.
  • the protective caps are no longer offer reliable protection if the neck thread is corroded and can even be a source of danger. If the neck thread is corroded, it often happens, especially when transporting the steel bottles by hand, that the protective caps slip off and accidents are caused.
  • Another disadvantage of the protective caps is that they have to be removed for gas extraction. As a result, the gas sampling valve is not protected during removal. In addition, the removed protective caps are easily lost, especially on construction sites. Your replacement is then expensive. Especially on construction sites, the protective caps also pose a danger in that they are often unscrewed with unsuitable tools.
  • the invention has for its object to provide a device for protecting the gas bottle valve of gas bottles, which is safe even with a corroded neck thread and overall allows a simpler and easier handling of the bottle during transport and gas extraction.
  • the clamping ring contains a slot in a manner known per se which can be bridged and narrowed by a screw connection.
  • the clamping ring screwed onto the neck ring is thus both form-fitting through the screw connection and non-positive due to the clamping connection firmly connected to the steel bottle. If the neck thread is intact, each of these connections already represents a secure connection. If the positive connection fails if the neck thread is corroded, the clamp connection still provides a secure connection between the steel bottle and the protective device. Slipping of the protective device, for example when the bottles are transported by hand, is definitely not possible. Steel bottles with a corroded neck thread can thus also be handled safely when using the protective device according to the invention.
  • Another advantage of the device according to the invention can be seen in the fact that the gas cylinder valve remains protected even during gas extraction, since the protective device for gas extraction does not have to be removed. Since the protective device remains screwed on even during gas extraction, there is hardly any possibility that the neck thread will corrode. On the other hand, corroded neck threads can be used without any worries, so there is no longer any need to replace neck rings. A loss of the protective device, for example on construction sites, and the associated transportation of steel bottles with unprotected valves is no longer possible.
  • Another advantage of the protective device according to the invention can be seen in the fact that safe crane transport is possible for the first time in gas practice by hanging the protective bracket in the crane hook. The highest region of the protective bracket is advantageously designed as a spherical section. This allows the steel bottle to be easily guided when rolling and gives the user a firm grip.
  • the protective device shown in Figures 1 to 3 consists essentially of the clamping ring 1 and the protective bracket 2, which are designed as a one-piece casting.
  • the clamping ring 1 is provided with the usual neck thread 3 so that it can be screwed onto the neck ring of the steel bottles.
  • the clamping ring 1 is divided by a slot 4.
  • the two ends of the clamping ring 1 formed by the slot 4 have openings 5 for receiving a screw which compresses the ends of the clamping ring 1 and thereby narrows the slot 4. This creates such a firm, non-positive connection between the clamping ring 1 and the neck ring of the steel bottle that the protective device sits securely on the neck ring, regardless of the condition of the thread of the neck ring.
  • the highest area of the protective bracket 2 is designed as a spherical section 6. This is advantageous for the bottle transport by hand, because the steel bottle can be easily guided when rolling with the help of the ball section 6. At the same time, the ball section 6 and the protective bar 2 give the user a firm grip.
  • the protective bracket 2 is designed so large that there is still enough space above the gas bottle valve to hang the gas bottle with the protective device in a crane hook.
  • the protective device according to the invention does not necessarily have to be designed as a cast construction, even if this is usually the most advantageous, for example made of malleable cast iron, cast steel and cast iron. Welded constructions or composite constructions, in which, for example, the protective bracket is screwed to the clamping ring, are also possible.
