Definitions

  • the invention relates to a gas pressure control system.
  • Gas pressure control systems can be found e.g. B. in the supply of a consumer in a caravan or caravan using fuel gas.
  • the gas pressure control system on the bottle valve of a supply bottle that holds liquid gas screwed on or coupled by means of a high pressure hose.
  • the operating pressure regulator provided in the gas pressure control system regulates the high one Bottle pressure (e.g. 16 bar) to one for the downstream consumer suitable operating pressure (e.g. 30 mbar).
  • each of the bottles with its own pressure regulator to be provided the operating pressure regulator belonging to the operating bottle is set to a somewhat higher value (e.g. 33 mbar) than one to Reserve pressure regulator belonging to the reserve bottle (e.g. 27 mbar).
  • the controller outputs are brought together via a T-piece and connected to the consumer. This means that the pressures emitted by the regulators stand against each other, so that in the event of a gas request from the consumer initially exclusively Pressure is supplied by the company bottle.
  • Similar gas pressure control systems are also from DE 298 02 433 U1, the DE-GM 722 91 47 and DE-GM 169 04 91 are known. It is also possible here to switch between a first and a second gas storage bottle, wherein The operating principles of these systems are based on the fact that for every gas storage bottle a separate pressure reducing valve is available, the pressure chambers of the two Pressure reducing valves are interconnected and the pressure reducing valves are set to different high control pressures. The pressure drops in one of the gas cylinders under the pressure on the pressure reducing valve for the lower pressure is set, an automatic switchover to other gas storage bottle.
  • the medium pressure regulator of the operating bottle is set to a higher value (e.g. 600 mbar) than the medium pressure regulator the reserve bottle (e.g. 300 mbar).
  • the outputs of the medium pressure regulator are in turn merged and sent to an operating pressure regulator directed to the operating pressure required by the consumer (e.g. 30 mbar).
  • the invention has for its object to provide a gas pressure control system, that while maintaining the functional advantages of the already known systems is simpler in construction, requires fewer parts and can be easily retrofitted is.
  • three connections are to Connection of two gas storage bottles and one consumer provided whereby - as already known - before the third connection for the consumer Operating pressure regulator is attached.
  • the operating pressure regulator is connected to the first connection, which is used to connect the operating bottle, via a three-way element coupled, at the then still free end a valve, preferably a check valve is provided, which in turn with one on the second connection and thus the medium pressure regulator provided on the reserve bottle is coupled.
  • the valve is designed so that there is a gas flow allows only in one direction, from the medium pressure regulator to the three-way element. But this only if there is a pressure drop in the flow over the valve, d. i.e. when the pressure is on the three-way element side is lower than the pressure on the side of the medium pressure regulator.
  • the gas pressure control system according to the invention can also be carried out in a simple manner in existing gas supply systems, in which e.g. B. a supply bottle with operating pressure regulator, retrofit by the three-way element between the bottle valve belonging to the flat and the existing one Operating controller is installed together with the other components.
  • B. a supply bottle with operating pressure regulator
  • This has the advantage that the already existing components function Retain and therefore no component is superfluous even after the expansion becomes what enables an economical use of all components.
  • a pressure display provided to display a pressure upstream of the operating pressure regulator.
  • a signaling device that can be pressurized, which falls below a predetermined pressure in the system emits a signal that the Users - e.g. B. in the interior of his caravan - can be displayed.
  • the Signal generator can also be designed such that it has a valve position of the Check valve detected.
  • FIG. 1 In the first embodiment of the gas pressure control system according to the invention shown in FIG. 1 is a company bottle 1 filled with liquid gas Bottle valve 2 at a first connection 3 at one end 4a of a three-way element serving T-piece 4 coupled.
  • Another end 4b of the T-piece 4 communicates with an operating pressure regulator 5, which has a third connection 6 for a consumer, not shown, e.g. a heater in a caravan, with pressure-reduced gas from z. B. 30 mbar feeds.
  • a consumer not shown, e.g. a heater in a caravan, with pressure-reduced gas from z. B. 30 mbar feeds.
  • a pressure switch 8 At a still free third end 4c of the T-piece 4 are one after the other Pressure gauge serving pressure gauge 7, a pressure switch 8, a check valve 9 and a medium pressure regulator 10 are arranged.
  • the medium pressure regulator 10 will via a second connection 11 from a liquid gas also filled Reserve bottle 12 fed with a bottle valve 13.
  • the check valve 9 is installed such that there is only a gas flow of allows the medium pressure regulator 10 to the T-piece 4, but not vice versa.
  • the operating pressure regulator 5 When requested by the consumer, the operating pressure regulator 5 generates one Gas flow at the third connection 6 with a gas pressure of 30, for example mbar. Due to the bottle pressure at the check valve 9 (16 bar) the check valve 9 is kept closed. On the other side of the Check valve 9 is a regulated by the medium pressure regulator 10 and the reserve bottle 12 fed gas pressure of, for example, 600 mbar, the is not sufficient to open the check valve 9. This will on the one hand ensures that the high bottle pressure from the operating bottle 1 is not in existing between the check valve 9 and the medium pressure regulator 10 Penetrate pipes or hoses 14 and possibly cause interference can. On the other hand, it is prevented that already in regular operation, i. H. at Removal from the operating bottle 1, also gas from the reserve bottle 12 can be, so that an unnoticed emptying of the reserve bottle 12th is prevented.
  • the operator can use the manometer 7 Read the status of the system. If the manometer 7 has a pressure in the Order of magnitude of the pressure from the medium pressure regulator 10 means that that the operating bottle 1 is at least largely emptied.
  • This state can also be caused by the pressure switch 8 serving as a signal transmitter be recognized, the signal when the pressure falls below the predetermined generated that is displayed, for example, inside the vehicle to be heated can be.
  • the pressure switch 8 can also be coupled directly to the check valve 9 be and a position or a switching state of the check valve 9 detect and display.
  • the second embodiment of the invention shown in FIG. 2 basically has the same functionality.
  • the T-piece is 4, the operating pressure regulator 5 and the check valve 9 combined in one unit 20.
  • the assembly 20 can, for. B. be formed by a cast housing, whereby the separation and thus still required in the first embodiment Have sealing points between the individual components avoided. A reduced one The result is assembly and maintenance effort.
  • the manometer 7 and / or the Pressure switch 8 are integrated, thereby avoiding further sealing points to let. If necessary, it is also possible to use the manometer 7 or the Pressure switch 8 between the bottle valve 2 and the assembly 20 still also to be installed in the system.
