Definitions

  • the invention relates to a liquid supply system with a storage tank, a discharge line for dispensing liquid from the storage tank to at least one dispensing device, an emptying tank connected to the storage tank via a residual emptying pump and a residual emptying line, at least one arranged in the dispensing line and connected to the emptying tank by means of a separating line Liquid separator, at least one first pressure relief valve connected to the discharge line and the emptying tank by means of an overpressure line and a return line from the emptying tank to the storage tank provided with the pump.
  • Liquid supply systems of the type described at the outset are used, for example, for refueling aircraft, a storage tank being provided at the central point of an airfield, in which fuel is stored, pre-filtered by a filter.
  • the fuel is pumped from the storage tank by means of a pump into one or more delivery lines, which in turn are connected to delivery devices, for example in the form of hydrants.
  • a liquid separator in the case of an aircraft fuel in the form of a water separator, and at least one pressure relief valve for relieving the pressure of the discharge line are usually provided in the discharge line or lines.
  • a liquid separator is necessary because the liquid to be distributed is mixed with another Liquid, for example water is undesirable and can severely restrict the use of the liquid to be distributed.
  • a relief or safety valve is required to ensure that the entire fluid supply system is protected from damage from excessive pressure rise.
  • Such an increase in pressure can take place, for example, by heating the liquid, for example by intense solar radiation.
  • This problem occurs in particular in the case of liquid supply systems in the area of airfields, since some of the refueling systems are not arranged very deep in the ground and because the flooring of the airfield is heated up strongly in the event of strong solar radiation.
  • a residual emptying option is required for the storage tank, on the one hand to empty the storage tank, to carry out repair or maintenance work and, on the other hand, to pump off other liquids, for example water, that have accumulated in the base region of the storage tank.
  • Both the residual emptying line of the storage tank and the overpressure line connected to the pressure relief valve and the line emanating from the liquid separator open into an emptying tank, which in turn is connected to the storage tank by means of a return line.
  • the emptying tank usually has only a relatively small volume compared to the volume of the storage tank and the pipe system of the liquid supply system, so that the contents of the emptying tank have to be pumped back into the storage tank after a maximum fill level has been reached.
  • the problem often arises that the emptying tank overflows because too much liquid flows through the lines described above. This can be the case, for example, if the pump of the return line has a defect, so that the contents of the emptying tank cannot be pumped back into the storage tank.
  • the pressure relief valve is defective, an excessively large amount of liquid can be conducted into the emptying tank, which cannot be pumped back into the storage tank in sufficient quantity due to the comparatively small emptying pump.
  • the problem is further exacerbated by the fact that the residual emptying pump of the storage tank is started up in order to pump liquid, for example water, from the bottom area of the storage tank into the emptying tank. Since the sediment or sump of the storage tank is usually pumped out at regular intervals, it can happen that such overfilling of the emptying tank is not noticed by the operating personnel over a long period of time and thus large amounts of liquid run out of the emptying tank into the surrounding soil. This is undesirable for environmental reasons.
  • the invention has for its object to provide a liquid supply system of the type mentioned, in which an undesirable leakage of liquid is prevented with reliable construction and in which incorrect operation is excluded.
  • the object is achieved in that the residual drain line, the separating line and the pressure line open into a common inlet line of the emptying tank, that a first shut-off valve that closes with increasing filling of the emptying tank is arranged in the inlet line and that a second shut-off valve is provided in the discharge line downstream of the storage tank, which valve is actuated in the sense depending on the pressure in the inlet line that it closes with increasing pressure.
  • the liquid supply system according to the invention is characterized by a number of considerable advantages. Since the emptying tank only has one inlet line, it is possible to prevent overflow of the emptying tank by regulating the liquid flow through this inlet line.
  • the first shut-off valve arranged in the inlet line can ensure that a further liquid supply to the emptying tank is prevented. In this way it is ensured that an overflow of the emptying tank and thus an escape of liquid is prevented.
  • the second shut-off valve which is provided in the discharge line downstream of the storage tank, prevents liquid from being pumped out of the storage tank into the discharge line, which leads to the hydrant or dispensers. It is therefore impossible for the liquid supply system to be operated without first pumping out the emptying tank.
  • a particularly favorable embodiment of the liquid supply system according to the invention is provided in that the first shut-off valve by means of a second pressure relief valve comprehensive bypass line is bypassable.
  • This bypass line which is provided with a pressure relief valve, makes it possible to compensate for an increase in volume of the liquid located in the pipe system of the liquid supply system in order to prevent bursting or leakage.
  • the relatively small amounts of liquid that flow into the bypass line into the emptying tank with such a pressure equalization can be easily absorbed by the latter without the emptying tank overflowing and liquid escaping from it. It proves to be particularly advantageous if the second pressure relief valve has a trigger pressure that is greater than the pressure that can be applied by the residual drain pump.
  • the residual drain pump in the storage tank is put into operation by means of a time control, for example in order to pump out the water accumulated in the bottom area of the tank, the actuation of the residual drain pump is beyond the attention of the operating personnel, so that it must be ensured that the drain tank is already completely full that further pumping in of liquid is prevented by the residual drain pump.
  • Appropriate coordination of the triggering or response pressure of the second pressure relief valve thus ensures that the residual drain pump no longer has a delivery effect when the first shut-off valve is closed. This measure, which does not require any external energy, achieves a high degree of operational safety, so that accidental pumping out of liquid from the bottom area of the storage tank is avoided.
  • the first shut-off valve can be actuated by a float arranged in the emptying tank. This configuration ensures that the first shut-off valve is actuated automatically at a certain liquid level in the emptying tank, without additional manipulations by an operator being required and without additional external energy having to be used.
  • the closing of the first shut-off valve takes place exclusively in that the float assumes a predetermined position corresponding to a maximum filling.
  • the first shut-off valve has an actuating device which comprises an actuating element connected to a shut-off element of the shut-off valve, which limits at least one working chamber which can be pressurized and that the pressurizing of the working chamber is determined by the float position.
  • actuating device which comprises an actuating element connected to a shut-off element of the shut-off valve, which limits at least one working chamber which can be pressurized and that the pressurizing of the working chamber is determined by the float position.
  • the pressure accumulator which can be pressurized by the pump arranged in the return line connecting the emptying tank to the storage tank, it is also possible to dispense with the use of external energy. This not only increases the operational reliability of the system itself, it also prevents electrical installations, for example in the case of flammable or potentially explosive liquids, which often cannot be designed to be explosion-proof or can only be carried out with considerable effort.
  • the second shut-off valve has an actuating device which comprises an actuating element connected to a shut-off element of the shut-off valve, which delimits at least one working chamber which can be pressurized, and in that the working chamber with the pressure in the inlet line upstream of the first Shut-off valve is acted upon, the second shut-off valve being open when the working chamber is not pressurized.
  • An operational connection is thus created directly between the pressure upstream of the first shut-off valve and the actuating device for the second shut-off valve, so that it can be prevented that liquid is still pumped from the storage tank into the pipe system of the liquid supply system by the dispensing pump arranged in the dispensing line.
  • a device for closing the first shut-off valve is advantageously provided in the area of the emptying tank for functional testing. This makes it possible to check the response of the second shut-off valve as a function of an increase in pressure in the inlet line.
  • the first shut-off valve is provided with an alarm device.
  • an alarm device This can be done in a simple manner acoustic warning device or in the form of an optical warning device which includes, for example, an electrical switch which is also operated when the first shut-off valve is closed.
  • a further advantageous embodiment is provided in that the discharge line is connected to the inlet line of the emptying tank via a manual emptying line provided with a manually operable valve.
  • a manual drain line is necessary, for example, to empty the pipe system before carrying out work.
  • the connection of the inlet line to the manual drain line ensures that even if the manual drain valve is operated incorrectly, an overflow of the drain tank is avoided in a safe manner.
  • the liquid supply system shown in FIG. 1 has a storage tank 1, which is provided with a dispensing device 3 via a dispensing line 2.
  • the dispensing device 3 can be designed in the form of a hydrant arranged in a shaft, as in the region of Airfields is common.
  • the liquid supply system also has an emptying tank 4, which is used to receive and temporarily store certain quantities of liquid which are derived from the pipe system of the liquid supply system, in particular the discharge line, before they are pumped back into the storage tank 1 via a return line 11 by means of a pump 12 becomes.
  • the emptying tank 4 has an inlet line 13 in which a first shut-off valve 14 is arranged.
  • a normally closed drain line 46 is switched into the return line and can be used to remove water from the system.
  • the liquid in the storage tank 1 is pumped into the discharge line 2 by means of a discharge pump 30.
  • the dispensing pump 30 can be actuated by means of a motor 31.
  • a check valve 32 is provided downstream of the delivery pump 30. Downstream of the check valve 32, a liquid separator 8 is arranged in the discharge line 2, which in the present example is a liquid supply system for refueling aircraft in the form of a water separator.
  • the separated water is fed to the emptying tank 4 by means of a separating line 7, in which separating valves 33a, 33b are interposed.
  • a first pressure relief valve 10 is provided in the discharge line 2, which is opened at a predetermined pressure in the discharge line 2 and supplies liquid through the pressure line 9 to the emptying tank 4. Furthermore, the liquid supply system has a manually operable valve 28, when opened, the valve in the discharge line 2 liquid is also supplied to the emptying tank 4 through a manual emptying line 29.
  • the first pressure relief valve 10 is required to prevent destruction of the discharge line or other components of the liquid supply system when the liquid is heated.
  • the manually operated valves 28, 33a are required in order to empty the discharge line 2 in the event of repairs or maintenance work.
  • the pressure line 9, the separating line 7, the manual drain line 29 and the residual drain line 6 all open into the inlet line 13, so that when the first shut-off valve 14 is closed it is ensured that no liquid can get into the emptying tank.
  • a residual drainage pump 5 is provided which can be actuated by means of a motor 34.
  • the residual emptying pump 5 conveys the liquid through a residual emptying line 6, which also opens into the inlet line 13, to the emptying tank 4.
  • the residual emptying pump is usually actuated periodically after certain time intervals to ensure that as little water as possible is in the area of the storage tank 1.
  • a second shut-off valve 15 is provided, which is opened or closed depending on the pressure in the inlet line 13. The function of the second shut-off valve 15 will be described in detail below.
  • a bypass line 16 is provided, which is connected to the inlet line 13 and can be closed by means of a second pressure relief valve 17.
  • the response pressure of the second pressure relief valve 17 is selected so that it is greater than the pressure that can be generated by the residual drain pump 5, so that the second pressure relief valve can remain closed even when the residual drain pump 5 is in operation.
  • the second pressure relief valve serves to prevent excessive pressure in the discharge line 2 or in one of the lines connected to it, in order to prevent leakage or bursting, for example when the liquid is heated.
  • a float 18 Arranged in the emptying tank 4 is a float 18 which, as will be described below, serves to actuate the first shut-off valve 14.
  • the second shut-off valve 15 can either be provided as a separate shut-off valve, but it is also possible to use a shut-off valve which is usually already provided in the discharge line 2 in the manner according to the invention.
  • the actuating device for the first shut-off valve 14 is shown in a schematic manner.
  • the shut-off valve 14 has an actuating device 19 which comprises a shut-off element 20 for the first shut-off valve 14.
  • the peripheral region of the actuating element 21 is connected to a housing of the actuating device 19 via an elastic membrane 35.
  • the membrane 35 and the actuating element 21 delimit a working chamber 22 which can be acted upon by fluid pressure via a pressure line 36.
  • a biasing device in the form of a spring is arranged in a second working chamber 38, which biases the actuating element 21 and the shut-off element 20 into a closed position of the shut-off element 20.
  • the actuating device 19 thus closes the first shut-off valve 14 when no pressure is supplied to the working chamber 22 through the pressure line 36.
  • An alarm device 27 is arranged on the upper area of the actuating device 19, which, for example is designed in the form of an electrical switch and serves to activate an electrical or acoustic warning signal when the first shut-off valve 14 is closed.
  • the float 18 is operatively connected to a control valve 23 which is connected to the pressure line 36 and to a line 37 which supplies pressure fluid from a pressure accumulator 24.
  • a control valve 23 which is connected to the pressure line 36 and to a line 37 which supplies pressure fluid from a pressure accumulator 24.
  • a working chamber 38 is provided in the actuating device 19, which is connected by means of a line 39 in the position of the float shown in solid lines to an inlet line 40 which opens into the interior of the emptying tank 4. If the float 18 is brought into the position shown in dashed lines when the liquid level in the emptying tank 4 rises, this causes the control valve 23 to be actuated, as a result of which the lines 37 and 39 are operationally connected, so that a pressure increase in the working chamber 38 takes place, through which , additionally by the force of the biasing device 25, the first shut-off valve 14 is closed.
  • the pressure line 36 is via the inlet line 40 relieved of pressure to the interior of the emptying tank 4.
  • a screen filter 41 is also arranged, which is used to clean the liquid used to actuate the control valve 23.
  • This arrangement described has proven to be particularly reliable, since the first shut-off valve can be opened and closed without the aid of external energy. If, despite pressure monitoring by the pressure switch in the pressure accumulator 24, there is not sufficient operating pressure, the force of the pretensioning device 25 is sufficient to nevertheless close the first shut-off valve 14.
  • the control valve 23 is designed such that there can be no overlaps in the control times, ie no intermediate positions are possible in which the lines 36, 37, 39 and 40 would be connected to one another in an undesired manner.
  • a device 45 with which the float 18 can be manually operated is used to test the function of the control valve 23 and thus of the first shut-off valve 14.
  • the second shut-off valve 15 shown in FIG. 1 is designed in an analogous manner to the first shut-off valve 14. A detailed description can therefore be dispensed with.
  • the working chamber of the second shut-off valve 15, which corresponds to the working chamber 38 of the first shut-off valve 14, is pressurized via a shut-off line 42, which supplies the pressure upstream of the first shut-off valve 14 to the working chamber. If the first shut-off valve 14 is closed, this leads to an increase in pressure in the inlet line 13 and thus to a closing of the second shut-off valve 15.
  • shut-off valves 14 and 15 are actuated exclusively hydraulically, it is not necessary to use external energy. This results in a high degree of operational safety, since malfunctions can be ruled out due to a lack of third party energy.
  • the invention is not restricted to the exemplary embodiments shown; rather, it is possible within the scope of the invention to change, in particular, the configuration of the discharge line and the number and configuration of the various lines leading from the discharge line into the emptying tank.
  • shut-off element was generally referred to with the term valve. It is therefore equally possible according to the invention to use the most varied types of shut-off elements.
