Definitions
- the invention relates to pressure compensation Direction for heating systems or the like, with the heating medium absorbing, sealed off from the outside air NEN expansion tank, which is connected via lines to the heating plant is connected, being within the compensation area holder closed off from the expansion tank ne chamber with variable volume is provided, the communicates with the outside air, and the compensation container via a pressure regulating the heating system Pump and an overflow valve with the heating system in Ver binding is established, with one attached to a pressure sensor closed electronic control device for the pump.
- such a pressure compensation device can be used in any system where there is a Medium volume changed, so also with cooling systems.
- the disadvantage here is that in the open storage container the heating fluid comes into contact with the outside air, which is the main risk of corrosion within the system enlarged.
- a pressure compensation device is now known at the ask the heating medium water against the outside air remains closed.
- This pressure compensation device essentially consists from a pressure vessel and an automatic compressor group, for smaller units directly on the container is mounted. For larger systems, the parts of the Automatic placed separately.
- the structure of the container is such that between the Rubber hose and the container wall there is an air space, which is under pressure by its own compressor, namely under the pressure of the system.
- An adjustable bares piston manometer with limit switches controls the Compressor and opens a solenoid valve in the event of overpressure, so that the pressure is kept constant at approximately ⁇ 0.2 bar can be.
- the function of the pressure compensation device is as follows: If more water is fed into the hose from the system, air is let out from the space between the tank wall and the hose to keep the pressure constant. When the heating medium flows out of the hose, the resulting additional space in the ring gap is filled up with air pumped in by the compressor.
- This pressure compensation device has the advantage that the Containers only a small fraction of the pressure of the Heating system must record. So it can't with one reservoirs subject to inspection must be worked.
- the object of the invention is a pressure compensation device to improve the generic type in such a way that due to slight pressure fluctuations in the system loosened rattling of the pump is avoided.
- the time period for the pump run is preferably 2 minutes.
- FIG. 1 schematically shows a pressure according to the invention Compensating device under construction
- Fig. 2 shows schematically a pressure compensation device in plan view.
- the actual compensation is at 14 container and with 5 an electronics arranged in front of it Designated control device.
- the pressure equalization Direction is via a line 15 with the actual Heating system in connection.
- the additional water created by the expansion of volume is via line 15 through a pressure valve 2 the line 16 is fed to the expansion tank 14.
- a pump 4 When the pressure or volume in the heating system is reduced, a pump 4 is automatically activated via a pressure switch 3 and pumps water back into the heating system via lines 15, 17, 18.
- the function of the pressure compensation device according to the invention is as follows: The heating system is filled up to its static pressure, taking into account any evaporation pressure in systems with over 100 ° C. In the expansion tank 14, water in the order of 20% of the vessel volume is filled via a fill and drain tap. Reaching the 20% can be seen on the water level indicator 6
- the pressure switch 3 is set to the setpoint, ie static height plus 5 m. In systems for over 100 ° C, the evaporation pressure must also be added. ie the setpoint would then be static height plus 5 m plus evaporation pressure.
- the system pressure would exceed the selected maximum system pressure (e.g. 2.5 bar) would increase.
- the selected maximum system pressure e.g. 2.5 bar
- the pump 4 After the set time has elapsed (e.g. 2 min.) the pump 4. The minimal excess built up in the system pressure is released via the overflow valve 2 and closes without generating pressure surges in the system 2.2 bar.
- a probe 7 is used, which is too low Water content when the pump is switched on or continued to run 4 prevented.
- a safety valve 8 with a Blow-off pressure of 0.5 bar is provided as a protection against overpressure when the overfill is overfilled equal container 14 .
- This security valve is used to drain excess water, which is closed off from the atmosphere in which Bubble 11 is located.
- the pressure compensation vessel 14 is open to the atmosphere.
- the vent 9 is with the overflow of the safe safety valve 8 connected so that an overflow funnel 10th must be installed.
- the bladder 11 is at the top and held down by a flange 12. It is there of particular importance that the air with the heating medium Water does not come into contact.
- overflow valve 2, the pressure switch 3, the pump 4 and the electronics control 5 are in a maintenance friendly control box 13 housed in the Figures of the drawings for clarity is drawn separately.

Abstract
Description
Wird in den Schlauch mehr Wasser von der Anlage zugeführt, wird Luft aus dem Zwischenraum zwischen Behälterwand und Schlauch nach außen gelassen, um den Druck konstant zu halten. Ebneso wird bei abströmendem Heizmedium aus dem Schlauch der dadurch bedingte zusätzliche Raum im Ring spalt mit durch den Kompressor hereingepumpter Luft auf gefüllt.
Die Heizanlage wird auf ihren statischen Druck aufgefüllt, wobei ein eventueller Verdampfungsdruck bei Anlagen mit über 100°C berücksichtigt werden muß. In den Ausgleichs behälter 14 wird über einen Füll- und Entleerhahn Wasser in der Größenordnung von 20% des Gefäßvolumens eingefüllt Das Erreichen der 20 % kann dabei an der Wasserstandsan zeige 6 abgelesen werden. Der Druckschalter 3 wird auf den Sollwert, d.i. statische Höhe plus 5 m eingestellt. Bei Anlagen für über 100°C muß der Verdampfungsdruck ebenfalls zugerechnet werden. d.h. der Sollwert wäre dann statische Höhe plus 5 m plus Verdampfungsdruck.
