Definitions

  • the invention relates to a pressure equalization device for heating systems or the like, with a compensating tank which absorbs the heating medium and is sealed off from the outside air and is connected to the heating system via lines, a chamber with a variable volume being sealed off from the compensating tank being provided within the expansion tank , which is connected to the outside air, and the expansion tank is connected to the heating system via a pump regulating the pressure of the heating system and an overflow valve, with an electronic control device for the pump connected to a pressure sensor.
  • such a pressure compensation device can be used in any system in which a medium changes in volume, that is to say also in cooling systems.
  • the disadvantage here is that the heating liquid comes into contact with the outside air in the open storage tank, which significantly increases the risk of corrosion within the system
  • a pressure compensation device is now known in which the heating medium water remains sealed off from the outside air
  • This pressure compensation device essentially consists of a pressure tank and an automatic compressor group, which is mounted directly on the tank in smaller units. In larger systems, the parts of the automatic system are placed separately
  • the structure of the container is such that there is an air space between the rubber hose and the container wall, which is kept under pressure by its own compressor, namely under the pressure of the system.
  • An adjustable piston manometer with end shadow controls the compressor and opens a solenoid valve in the event of overpressure so that the pressure can be kept constant at around ⁇ 0.2 bar.
  • the chamber is connected to the outside air, and the expansion tank is connected to the heating system via pump and valve devices regulating the pressure of the heating system, the volume change of the chamber depending on the prevailing within the expansion tank, vacuum generated by the pump
  • This pressure compensation device has the advantage that the container only has to absorb a small fraction of the pressure of the heating system. It is therefore possible to work with an expansion tank that is not subject to inspection.
  • this principle has the problem that the buffer vessel provided for damping the pressure fluctuations is not always sufficient in the event of extreme fluctuations, or is a component that requires a certain amount of maintenance.
  • the object of the invention is to improve a pressure compensation device of the generic type in such a way that rattling of the pump triggered by small pressure fluctuations in the system is avoided.
  • the electronic control device switches the pump on as a function of pressure but switches it off after a predetermined period of time regardless of the pressure
  • the period of time for the pump to run is preferably 2 minutes.
  • FIG. 1 schematically shows a pressure compensation device according to the invention in construction
  • FIG. 2 shows schematically a pressure compensation device in plan view
  • the actual heating system is not shown in the drawings, since it is not the subject of the invention and belongs to the self-evident knowledge of any person skilled in the art.
  • the pressure compensation device according to the invention can also be used in a wide variety of heating systems.
  • the actual compensation tank is designated by 14 and an electronic control device arranged in front of it is designated by 5.
  • the pressure compensation device is connected via a line 15 to the actual heating system.
  • the overflow valve 2 opens and allows the additional water volume to flow via the line 16 into the bladder 11 of the expansion tank 14.
  • the bladder 11 forms the variable volume chamber. The pressure in the system is kept constant by overflowing the water.
  • a time pulse is triggered in the electronic control 5, which causes the pump 4 to be switched off no longer in a pressure-dependent manner but in a time-dependent manner.
  • the overflow valve 2 opens in a pressure-dependent manner and directs the excess conveyed heating medium back into the expansion tank 14. After the set time has elapsed (e.g. 2 min.) - Pump 4 switches off. The minimum overpressure built up in the system is released via the overflow valve 2 and closes at 2.2 bar without generating pressure surges in the system.
  • a probe 7 is used in the vessel, which prevents the pump 4 from being switched on or running if the water content is too low.
  • a safety valve with a blow-off pressure of 0.5 bar is provided as a safeguard against excess pressure when the expansion tank 14 is overfilled. This safety valve serves to discharge excess water, which is isolated from the atmosphere, in the bladder 11
  • the pressure compensation vessel 14 is open to the atmosphere.
  • the vent opening 9 is connected to the overflow of the safety valve 8, so that an overflow funnel 10 must be installed.
  • the bladder 11 is held above and below by a flange 1 2. It is particularly important that the air does not come into contact with the heating medium water.
  • the overflow valve 2, the pressure switch 3, the pump 4 and the electronic control 5 are accommodated in a maintenance-friendly control box 13, which is drawn separately in the figures of the drawings for the sake of a better overview.
