Definitions

  • the invention relates to a system for dispensing liquid from a tanker truck having a plurality of chambers, each with at least one bottom valve, the bottom valves each being connected to a collector via a connecting line and a collector valve each, the collector being connected to at least one discharge valve via at least one discharge line is, and wherein the collector further comprises a degassing device.
  • the invention also relates to a corresponding method.
  • a collector which connects the bottom valves of the chambers of the tanker to a common discharge line or collection line, which leads to a discharge valve.
  • the collector usually has several collector valves assigned to the connecting lines to the bottom valves.
  • the collector is equipped with a venting device in order to discharge the air displaced as part of the inflow of the liquid.
  • a system with such a collector is known, for example, from EP 2 301 800 A2 .
  • the systems and methods mentioned at the outset are also known from WO 2004/106 218 A1 and DE 10 2010 050 576 A1 .
  • the liquid-carrying lines in particular the connecting lines between the collector valves of the collector and the bottom valves as well as the discharge line, have a gradient.
  • the center of gravity should be as low as possible. This and other design limitations limit the slope of the lines.
  • so-called flat bottom valves are installed. Due to the design, these form air bags in the connected lines, since the Bottom valves themselves are lower than the top edge of the connecting lines. As a result, air that enters the connecting lines between the collector valves and the bottom valves can only be vented to a limited extent into the respective tank chamber. It is not possible to lower the collector any further, as there is usually a measuring system for measuring the liquid discharged underneath the collector and, of course, sufficient ground clearance for the tanker must still be ensured.
  • the object of the invention is to provide a system and a method of the type mentioned at the outset with which the dispensing of liquid can be accelerated in a simple and reliable manner, especially at the beginning of the liquid dispensing, with high measurement accuracy.
  • the invention solves the problem in that at least two flow cross sections of different sizes can be released through the collector valves, and that a control device is provided which, for dispensing liquid from a chamber, uses the collector valve connected to the bottom valve of this chamber first opens with a smaller flow cross section, and then opens the collector valve with a larger flow cross section.
  • the invention solves the problem in that, in order to dispense liquid from a chamber, the collector valve assigned to the bottom valve of this chamber is first opened with a smaller flow cross section, and that the collector valve is then opened with a larger flow cross section.
  • the limited degassing performance of the degassing device of the collector can be taken into account.
  • the occurrence of an overpressure in the collector and the associated penetration of gas, in particular air, into the connecting line between the collector valve and the bottom valve can be avoided.
  • the collector valve is moved from the throttle position to a fully open position in particular, in which there is a larger, in particular the maximum flow cross-section to the delivery line.
  • the accuracy of a measuring device for measuring the volume of liquid dispensed is increased according to the invention, since each interruption in measurement that occurs in the prior art and is avoided according to the invention in the course of the beginning of liquid delivery leads to a start-up error due to the necessary acceleration of the moving parts and a lag of the measuring device, for example a turbine meter, and an associated inaccuracy.
  • the collector valves can each be designed in at least two stages. Of course, the collector valves can also be designed to release more than two flow cross sections of different sizes. A stepless adjustment of the flow cross sections is also conceivable.
  • the control device can in particular be an electronic control device.
  • the invention is particularly suitable for systems such as EP 0 895 960 B1 , EP 2 159 553 A2 or EP 2 301 800 A2 known. This applies in particular to the use of measuring systems that do not provide for any integrated venting, except in the supply line to the measuring system.
  • the invention can also be advantageously used in other systems for dispensing liquid. For reasons of contamination alone, operators of such systems often require the collector to be completely emptied when changing products, which inevitably results in the problem explained above. Even a conventional gas extractor system designed to separate air is regularly interrupted several times, resulting in the measurement inaccuracies and loss of time explained.
  • the control device opens the collector valve when the collector has been completely degassed via the degassing device with the larger flow cross section.
  • the degassing device can in particular be a venting device for venting the collector.
  • the Degassing device can have a degassing detector that indicates that the degassing of the Collector detected via the degassing device, wherein the degassing detector is connected to the control device.
  • the control device can open the collector valve after receiving a signal from the degassing detector that the collector with the larger flow cross-section has been completely degassed.
  • the control of the collector valve in particular the throttle position, can thus take place in a particularly simple manner parallel to the degassing device.
  • the degassing detector can, for example, detect that the collector is completely filled with liquid and cause the collector valve to open completely.
  • the control device opens the collector valve with the larger flow cross section after a predetermined opening time has elapsed after the collector valve with the smaller flow cross section was opened.
  • a period of time is thus defined during which the collector valve remains in the throttle position releasing the smaller flow cross section. After this time has elapsed, the collector valve is actuated to open the larger flow cross section. Due to the known dimensions of the system, in particular the volumes of the lines and the collector, the filling times with liquid at the beginning of a liquid delivery can be reliably determined in advance. It is thus possible to determine a time that elapses before the collector is sufficiently or completely filled, that is to say until there is sufficient or complete degassing. This period of time can then be specified for the opening of the collector valve with the smaller flow cross section.
  • the collector valves each have a valve piston that can be moved in an axial direction, the valve pistons being able to move between a closed position that closes access to the collector and in which the valve pistons each lie tightly against a valve seat and at least two opening positions that are lifted off the valve seat by different distances can be adjusted, in which the collector valve releases flow cross sections of different sizes to the collector.
  • Multi-stage valves are known per se in various configurations. In principle, any valve suitable in this respect can be used according to the invention. The configuration explained above is a practical variant.
  • the first open position which corresponds to a throttle position of the collector valve, is in particular closer to the valve seat or less far from the valve seat than the second open position, which is in particular the fully open position of the collector valve.
  • the piston of the respective collector valve can, for example, be activated pneumatically, hydraulically or in some other suitable manner. This is known per se.
  • the valve pistons can each be held at one end of a piston rod, at the other end of which a control piston guided in a control chamber is arranged.
  • the piston rods can each be guided in an axially movable manner in a ring seal, for example an O-ring seal arranged in a receptacle in a bore.
  • a control slot that bridges the ring seal at least in the closed position can be formed in each of the piston rods, with the control slots being connected to a first control line in the closed position and until the first open position lifted from the valve seat is reached, via which, controlled by the control device, a Pressure fluid, for example compressed air, can be introduced through the control slots into the respective control chamber in order to adjust the respective control piston and the respective valve piston via the respective piston rod into the first open position lifted off the valve seat.
  • the control slots can each be formed on the end of the piston rod facing the control piston and can each extend as far as the control piston.
  • the first control line opens out on the side facing away from the control room the ring seal into a guide bore that guides the piston rod.
  • the control pistons can each be seated on a control valve seat.
  • the control slots are each in a position in which they bridge the ring seal.
  • the first control line is connected to the respective control slot. Pressure fluid introduced via the first control line can therefore flow past the annular seal into the control chamber via the control slots and thus lift the control piston from a control valve seat.
  • the control slot In the first open position lifted from the valve seat, the control slot has moved past the ring seal, ie it no longer bridges it. The ring seal now separates the first control line from the control slot. A further opening of the valve via the first control line is therefore no longer possible.
  • the first opening position is precisely defined in a particularly simple manner without a position measurement or position control being required. Rather, the collector valves regulate themselves to the first open position. Any drop in pressure in the control chamber is also corrected automatically, since when the control piston and the piston rod are moved back, the control slot bridges the ring seal again, so that pressure is again exerted on the control piston via the first control line until the first open position is reached (again).
  • a pressurized fluid for example compressed air
  • the collector valves can only be actuated to reach the fully open position if the collector valves, actuated via the first control line, are on the way to their or preferably already in the first open position. This in turn further simplifies the structure of the system according to the invention. In this way, pressure can be applied to all second control lines of the collector valves via the control device. However, only the one or more collector valves that have previously been moved to the first open position are moved to the fully open position.
  • each of the second pressure lines can be assigned a pneumatic control valve, which is preloaded into a closed position in which it does not permit pressurized fluid to be introduced via the second control line into the control chamber of the collector valves, and which is brought into an open position by pressure fluid introduced via the first pressure lines, in particular an associated pressure build-up, in which it allows pressure fluid to be introduced via the second control line into the control chamber of the collector valves.
  • a pneumatic control valve which is preloaded into a closed position in which it does not permit pressurized fluid to be introduced via the second control line into the control chamber of the collector valves, and which is brought into an open position by pressure fluid introduced via the first pressure lines, in particular an associated pressure build-up, in which it allows pressure fluid to be introduced via the second control line into the control chamber of the collector valves.
  • the degassing device can comprise at least one degassing line connected to the collector.
  • the degassing line can in particular be open to the atmosphere or connected to a gas recycling system.
  • At least one gas bubble sensor can also be arranged in the at least one delivery line.
  • at least one volume meter can be arranged in the at least one delivery line to measure the quantity of liquid delivered, preferably a turbine meter.
  • the system according to the invention can basically be designed as in EP 0 895 960 B1 , EP 2 159 553 A2 or EP 2 301 800 A2 described.
  • the system can be designed, for example, for dispensing liquid under the force of gravity.
  • the invention is not only suitable for systems with gravity discharge, but also for systems with liquid discharge taking place by pumps.
  • the gas bubble sensor detects gas bubbles, in particular air bubbles, in the delivery line and switches off the liquid delivery to avoid gas bubbles being incorrectly measured in the volume counter. It is precisely with such a system, which is advantageous in many respects, that the advantages according to the invention come into their own, since switching off the system at the beginning of the liquid delivery is largely avoided, in contrast to the prior art.
  • the collector valves can also be connected via at least one filling line to at least one filling coupling for filling the chambers via the bottom valves.
  • the chambers are then suitable for filling using the so-called bottom loading method.
  • the invention also relates to a tanker comprising a plurality of chambers, each with at least one bottom valve and a system according to the invention.
  • a tank 10 of a tank truck is shown.
  • the tank 10 has three chambers 12, 14, 16 in the example shown. Of course, more or fewer than three chambers can also be provided.
  • Each chamber 12, 14, 16 is assigned a bottom valve 18, 20, 22 on the underside.
  • the bottom valves 18, 20, 22 are each connected to a collector 36 via a connecting line 24, 26, 28 and a collector valve 30, 32, 34.
  • a common output line 38 is connected to one end of the collector 36 .
  • the collector 36 supplies liquid from the connecting lines 24, 26, 28 to the common delivery line 38 in a manner known per se.
  • the delivery line 38 is in the figure 1 located on one side of the collector 36. Of course, it could also be connected to the collector 36 at other positions.
  • the collector 36 could also consist of several segments with different inclinations.
  • a volume meter 42 for example a turbine meter, is also arranged in the common delivery line.
  • a delivery valve 44 is provided on the outflow side of the volume meter 42 .
  • a discharge hose can be connected to this, for example.
  • the liquid can be discharged from the chambers 12, 14, 16 and via the connecting lines 24, 26, 28 and the discharge line 38 and the discharge valve 44, for example, due to the force of gravity.
  • the liquid could also be dispensed by pumping.
  • a pump can be located between the collector 36 and the volume meter 42, for example.
  • Reference number 40 also shows a degassing valve of a degassing device of collector 36 , which opens into a degassing line 41 .
  • Gas for example air
  • the degassing valve 40 and the degassing line 41 are discharged from the collector 36 via the degassing valve 40 and the degassing line 41, for example into a gas recirculation system.
  • a degassing valve 40 with a degassing line 41 could also be arranged at the other end of the collector 38 in order, for example, to ensure proper degassing even when the vehicle is tilted.
  • An empty signaling sensor is also arranged on the delivery line 38 at the reference number 46 .
  • An electronic control device 48 controls the system and its individual components via suitable control lines, as will be explained below. It also receives signals from the sensors and measuring devices of the system via suitable lines, in particular from the volume counter 42 and the empty signaling sensor 46.
  • the volume counter 42 can also be preceded by a gas bubble sensor (not shown). Signals from the gas bubble sensor can also be made available to the control device 48 via a suitable line, so that it can be prevented that gas bubbles are also measured by the volume counter 42

  • the collector valve and its function are explained below with reference to the collector valve 30 .
  • the other collector valves 32, 34 can be identical in terms of structure and function.
  • a piston 52 is shown, which can be actuated by a piston actuating device 54, for example a pneumatic actuating device, via a piston rod 56, in particular can be moved in the axial direction of the piston rod 56.
  • the closed position of collector valve 30 is shown. In this, the piston 52 lies tightly against a valve seat 58 on the inside of the housing of the collector valve 30 .

  • the bottom valve 12 is opened under the control of the control device 48 and the piston 52 of the collector valve 30 moves into the in 2 axial position (throttle position) shown at reference numeral 60. Liquid then flows out of the chamber 10 via the connecting line 24 in the collector 36, as far as permitted by the throttle position of the piston 52. In particular, due to the small flow cross section released in the throttle position, there is no harmful excess pressure in the collector 36, which could lead to air penetrating into the connecting line 24.
  • the air displaced from the collector 36 by the incoming liquid is safely discharged via the open degassing valve 40 and the degassing line 41, for example into a gas recirculation system.
  • the liquid flowing into the collector 36 then continues to flow through the common discharge line 38 to the discharge valve 44. It should be understood, however, that the state of complete emptying is not a prerequisite for the use of the invention. When a chamber is emptied, air inevitably enters the collector 38 . If then, during the same delivery process, a switch is made to another chamber that is not empty, the same process begins to take place according to the invention.

  • the length of time can be chosen so that the collector 36 is already essentially completely filled with liquid, so that there is no longer a risk of air inclusions.
  • the dispensing valve 44 can be opened and full-rate liquid dispensing can occur.
  • the dispensing valve 44 can be opened, for example, when the gas bubble sensor detects that the dispensing line 38 is completely full.
