Definitions

  • the invention relates to a method and a device to secure a gas powered device and in particular a gas heater to which a gas pipe leads, in the one main shut-off device, a counter and in between a gas pressure regulator and preferably an in this integrated safety shut-off valve arranged could be.
  • facilities of the above can also be used Type without main shut-off device and / without gas pressure regulator exist or be built. This too Cases are the subject of the invention.
  • the invention is therefore based on the object of measures provide with the help of simple and unproblematic Way and at the lowest possible cost an interruption in the gas supply in the gas line is achieved can be.
  • the invention provides the features of claim 1 before that the gas line in the flow direction in front of the gas powered facility Closed with the help of a remote control device.
  • the remote control device can be used in more or less arranged at a great distance from the gas line and its consumer be and allowed in a straightforward and safe manner Way the interruption of gas supply. This will preferably using a pressure in a flow medium the remote control device generated and expedient for closing a safety shut-off valve arranged in the gas line used.
  • the remote control device includes a permanent, independent Energy source and one to the gas line or the safety shut-off valve leading management as well as an integrated trigger element that can be operated by hand.
  • the trigger element is conveniently located outside the building, where the gas powered facility and its Auxiliary units and the gas line are located. It is therefore possible, if there is a danger, the gas supply from a safe place to interrupt.
  • a gas-operated device 1, in particular according to Exemplary embodiment of a gas heater is according to 1 in a building 2 and is via a gas line 3 connected to a gas network 4.
  • a main shut-off device in the gas line 3 6 for example in the form of a manually operable Shut-off valves and further are according to the embodiment a gas pressure regulator 7 with a preferably integrated Safety shut-off valve 8 and a counter 9 available.
  • the remote control device 10 comprises an energy source 11 and one to the housing 12 of the gas pressure regulator 7 respectively to a housing part 13 of the safety shut-off valve 8 leading line 14 and one of these lines 14 assigned trigger element 15 which can be actuated by hand (Figs. 2 and 3).
  • An auxiliary pressure or inert gas which is at a pressure which is significantly higher than the gas pressure prevailing in the gas line 3 is preferably used as the energy source.
  • carbon dioxide (CO 2 ) is expediently used as the inert gas and can be located, for example, in a bottle 16 which can be connected to the working chamber 18 of the safety shut-off valve 8 via a capillary tube 17 serving as a line 14.
  • a pipe connection piece 18 ' which also expediently has a check valve 19, the capillary tube 17 is connected on the working chamber side to the housing part 13 of the actuator 8' (FIG. 2).
  • FIGS. 2 and 3 is the bottle 16 containing the inert gas in one Bottle holder 20 arranged. Furthermore, a closure element 21 assigned to the bottle holder 20 and has the trigger element 15, with the help of a flow path if necessary from the bottle 16 via a with the closure element 21 connected tube piece 22 to the capillary tube 17th can be manufactured. 3 is a needle-like Part 23 moved with the aid of the trigger element 15, if an increased pressure in the working chamber for safety purposes 18 of the safety shut-off valve 8 is generated shall be.
  • Bottle holder 20 with the bottle containing the inert gas 16 expediently in a safety box 26 outside of building 2 is / can be accommodated.
  • the Capillary tube 17 immediately adjoins tube section 22 in the safety box 25 and thus connects if necessary the bottle 16 with the actuator 8 'of the safety shut-off valve 8.
  • the trigger element 15 can be behind a glass pane 27 are located, which are struck if necessary must be, as is also known from fire alarms.
  • FIGS. 4 and 5 A modified embodiment is shown in FIGS. 4 and 5 shown, here only one safety shut-off valve in the gas line 3 is provided.
  • the main shut-off device is missing 6 and the gas pressure regulator 7. Also in in this case there is an interruption in the gas supply in the Gas line 3 at any time using the remote control device 10 possible. It is on the safety shut-off valve 8 connected so that the function and mode of operation are the same are as in the first embodiment described. This is also made clear by the identical ones Reference numbers for basically identical parts.
  • the safety shut-off valve 8 is also a conventional shut-off valve 6 replace according to FIG. 1, in addition the positive Side effect occurs that also hedging the downstream fittings against an impermissible pressure takes place, as is usually done by the safety shut-off valve happens.
