Definitions

  • the invention relates to a mechanical coupling, one coupling half A of which is arranged on a reusable container and the other coupling half B of which is part of a dispensing system for viscous fluids (e.g. lubricating oils) according to the preamble of claim 1.
  • viscous fluids e.g. lubricating oils
  • viscosity index In contrast to the liquids mentioned above, these fluids represent a different class of substances, with completely different physical and chemical properties, which in particular have considerable effects on their hydraulic capacity, which in turn depends on the operating temperature and - in the present case negligible - the operating pressure and their Expressed in the respective viscosity / temperature behavior ("viscosity index"). These viscous properties are assigned to every liquid and gaseous substance; they are undesirable per se for conveying processes with higher viscosities, but must be accepted in terms of material. Their temperature dependence for lubricants can only be influenced to a limited extent, for example by special additives for multi-grade and low-viscosity oils.
  • viscosity is a substance quantity for the internal resistance of a flow, which is caused by a velocity gradient in a plane perpendicular to Flow direction (adhesion of the fluid to the wall of a pipe or full flow velocity in the middle of the pipe) arises and results in a shear stress in the transverse direction ("shear flow”).
  • This internal resistance contains an internal friction, leads to internal warming and thus to a loss of energy (“dissipation”); technically it manifests itself in a pressure loss in the pipeline along the flow direction; this loss can be considerable, depending on the viscosity, among other things.
  • the containers on which these couplings have so far been arranged are used for the transport, storage and removal of these low-viscosity liquids.
  • the lengthwise and / or branching of such dispensing systems with which the containers are coupled and their dispensing quantities per unit of time are relatively small (for example beer dispensers).
  • the working pressure required depends, among other things, on the operating viscosity. It is therefore sufficient to put such a reusable container under the pressure of an external pressure source in order to effect a conveying process (eg carbon dioxide bottle when dispensing beer). If the pressure bottle is empty, the delivery is zero; is also a such equipment is difficult to automate and represents a certain potential hazard if used improperly.
  • the energy input is arranged behind the container and is usually automated (e.g. full hose system for calibrated fuel delivery). Due to the almost constant working pressure required for the delivery, pressure relief valves can be easily arranged on the pressure side as hydraulic safety devices; their opening pressure only has to be higher than the required working pressure. If the system is now exposed to external heat (e.g. due to solar radiation), the static pressure in the system increases and the pressure relief valve may open. This pressure-side proper function of such a pressure relief valve is not given for fluids with temperature-dependent viscosity; this hydraulic arrangement would result in a hydraulic short circuit, in which the fluid would not reach the delivery point, but would instead be returned to the container.
  • a coupling known as a KEG fitting, for low-viscosity beer in a small dispensing system is recorded in the document DE-OS 1657209.
  • the energy is introduced by pressurizing a barrel with carbon dioxide.
  • the coupling On the barrel side, the coupling has only one check valve that can be unlocked during the coupling process.
  • a "manually operated valve or tap of conventional design can be provided" in the discharge line or in the carbon dioxide inlet, if desired.
  • an exchangeable air filter of a filling device for liquid containers is mentioned; how this should work when dispensing liquid remains open, since any check valves or the like. Not are provided.
  • a hydraulic safety device is claimed as a parallel expansion vessel on the pressure side in a full hose system.
  • a safety valve whose opening pressure is higher than the working pressure; where and how this valve is hydraulically switched remains completely open. It is by no means a component of the vacuum side of the system, which, moreover, does not have a coupling, since it is usually a container in the form of a stationary collection tank (eg underground tank).
  • a dispensing device according to the full hose principle for low-viscosity fuels is detected with a safety valve which is hydraulically connected in parallel to the pump between its pressure and suction side; its opening pressure must be higher than the working pressure of the full hose system.
  • the hydraulic resistance in the full hose system can increase so much that the working pressure is higher than the opening pressure of the valve and it leads to a hydraulic short circuit.
  • a coupling of the fluid container and the delivery system is not mentioned there.
  • the task is solved in a structural unit in the form of a mechanical fluid coupling, which consists of two coupling halves A and B; this coupling is arranged on the suction side in the complete fluid system on the reusable container; it is the interface of this container, which is interchangeable, and the stationary delivery system.
  • the coupling half A is an integral part of the transportable and exchangeable reusable container; the coupling half B, on the other hand, is generally mounted once in the suction line of the delivery system. Through the coupling process, the check valve in coupling half A is opened mechanically through coupling half B.
  • the 2nd check valve (suction valve) in the Coupling half B is only opened and only during the respective dispensing process by the suction effect of the pump in the dispensing system, otherwise it is closed, in particular also when no reusable container is coupled; it prevents the suction line of the delivery system from running dry.
  • Hydraulically connected in parallel to this valve in coupling half B is the back-relief valve on the suction side, which in the static state of the delivery system may reduce hydraulic pressures (e.g. in the event of expansion of the fluid due to heat effects) via coupling half A in the reusable container, which could lead to the bursting of a delivery line .
  • a ventilation and / or a moisture filter is integrated in the coupling half B, which in the coupled state is hydraulically / pneumatically connected to the reusable container via the coupling half A; it prevents dirt and / or moisture from entering the reusable container when it is in operation.
  • two reusable containers can be arranged hydraulically in parallel with two complete couplings on the suction side in front of the feed pump. This valve can be operated manually or also, electrically controlled, automatically electrically.
  • the hydraulic operating circuit of the complete fluid system (3) is shown in its simplest version with a tap (20) as a delivery point. It consists of a hydraulic conveyor (18) with a pump (21) and a drive motor (22); behind it is the pressure side (19) of the delivery system.

It is also conceivable for the reusable container (24) to be relieved of overpressure directly into the atmosphere, ie without via the coupling half B (9), which would also mean securing the barrel, for example during transport.
