Definitions

  • the invention relates to a method for automatic disconnection of fuel supply, in particular of gas supply to a consumer at the moment of stopping the consumer, said supply being controlled by at least one cylinder valve being influenced by the pressure in a pilot line. Furthermore, the invention also relates to a system for automatic disconnection of fuel supply, in particular of gas supply, to a consumer at the moment of stopping the consumer, which system comprises one or more fuel cylinders in fuel connection with the consumer by a supply line having at least one cylinder valve, said cylinder valve or valves being activated by a pilot line.
  • the pressure of the pilot line activating the valves in the system has to be lowered but the fuel or gas supply line must not be emptied due to the fact that a restart of the consumer is to be done in a smooth way, i.e. pressure shocks have to be eliminated in the system. If a restart is made with an empty supply line the risks are very high for having a pressure shock in the system resulting in more or less damages of the system.
  • Fig. 1 a general arrangement of a multipel cylinder system is shown involving the method of automatic disconnection of the fuel supply to a consumer M according to the present invention.
  • the system comprises a number of fuel tanks, in the present case in form of gas cylinders 1.
  • the gas cylinders 1 are arranged in blocks B of two or more cylinders each.
  • a charging unit 2 is in communication with the gas cylinders 1 through an inlet line 3 having a branch line 3' for each gas cylinder 1.
  • the cylinder valve 4 may be either a manually activated or a solenoid activated valve with respect to starting up the system, but for closing the gas supply it is controlled by a pilot line 11.
  • Each one of the gas cylinders 1 is in communication with thermal relief outputs 5.
  • a section of the inlet line 3 is used also as a feed line 6 to the consumer M.
  • Said feed line 6 involves a supply unit 7 having a manual stop valve 8, a fine filter 9, and a solenoid valve 10.
  • pilot line 11 is branched off downstream the valve 10.
  • the gas pressure in the pilot line 11 is used for automatic control of the cylinder valves 4 in such a way that the cylinder valves 4 close the gas supply when the pressure of the pilot line 11 drops beyond a predetermined low threshold level.
  • the system arrangement involves manual valves 12 and 13.
  • the manual valve 12 being used for evacuation of the fuel tanks or gas cylinders 1, and the manual valve 13 being used for interruption of the automatic control of the cylinder valves 4.
  • Fig. 2 The preferred embodiment of the system according to the present invention has a method of working as is shown in Fig. 2, which is self-explanatory.
  • the left hand side of Fig. 2 refers to the starting procedure of the consumer M and the right hand side thereof is the time schedule for automatic disconnection procedure of the gas (fuel) supply to the consumer M.
  • a stop activation is started, e.g. by pressing of an electric switch 14 (Fig. 3) in a control circuit for the gas (fuel) supply to the consumer M.
  • the supply valve 10 is managed to its closed position by a solenoid 10' belonging thereto.
  • a timer (I) is started for a delayed activation of a switch 15 controlling, e.g. the electric feeding of the consumer M.
  • timer (I) imply a delayed action of the consumer control switch 15
  • the consumer M is still activated for a time enough to consume the rest of the gas (fuel) in the pilot line 11 after the cylinder valves 4 are closed.
  • the timer (I) has run out the consumer M is shut down and is ready for a new start.
  • the pilot valve 16 has taken the form of a by-pass pipe and a needle valve inside the cylinder valve 4 (being described in more detail in the US document mentioned above, e.g. with reference to Fig. 4 thereof).
  • the pilot valve 16 is only working for a few seconds during the start up of the system to put the pilot line 11 under pressure for opening of the cylinder valve 4.
  • the further timer (II) returns to its off position after a predetermined time resulting in closing of the pilot valve 16.
  • the pressure in the feed line 6 by now has obtained working level the consumer M is operating and the cylinder valve 4 remains open.
  • the description given above refers to a consumer M in form of a combustion engine driven by natural or bio gas.
  • the very same method and system according to the invention may be applied also to other fuel or liquid or gas handling devices.
  • the consumer M can be in form of a fuel cell, a plant for unloading or discharging of fuel tanks or gas cylinders transported by trucks or trains or being of an unmovable construction.
  • the feed or supply valve mentioned as a solenoid one may also take the shape of another type, such as e.g. a hydraulic or pneumatic valve function of two or three way type.
  • the different solenoids and timers described in connection with Fig. 3 above may be driven by one or more voltages U1 - U4.
