Definitions

the invention relates to a device for expansion in liquid circulation systems, in particular heating or cooling systems, with at least one expansion vessel, preferably in gas exchange with the atmosphere, into which liquid is taken up from the liquid circulation system via an inlet line and from the liquid via an outlet line and a Pressure pump is fed back to the liquid circulation system and an overflow valve that can be adjusted to the operating pressure of the system is provided in the supply line to the expansion vessel, and wherein a lower pressure prevails in the expansion vessel than in the liquid circulation system, the inlet and outlet lines connecting the expansion vessel to the liquid circulation system, open into a prechamber, which is arranged at a lower level than the expansion vessel.
a device is known for example from EP-A1-0 292 814.
the prechamber is under system pressure during normal operation. The pressure only drops during the degassing phases, when the prechamber is connected to the expansion tank via a three-way valve.
EP-B1-0 313 599 describes a device in which water from the heating system is fed to the expansion vessel via an inlet line and is returned to the heating system via a separate outlet line. The water can be circulated in a cycle.
the object of the invention is to improve a device of the type mentioned in such a way that the oxygen uptake of the water is reduced and that the prechamber does not have to be brought to the system pressure.
the prechamber is constantly depressurized and is connected without pressure via a line to the expansion vessel, the overflow valve being located in the inlet line and the pressure pump in the outlet line.
the pressure and circulating pump continuously pumps liquid from the prechamber into the circulatory system and, with appropriate dimensions, ensures that the operating pressure in the circulatory system is maintained, to which the overflow valve in the feed line to the prechamber is set.
at least part of the circulating liquid flows continuously through the overflow valve into the prechamber.
the circulating liquid temporarily more liquid passes through the overflow valve into the prechamber and thus into the expansion vessel than is conveyed from it by the pressure and circulation pump. This increases the liquid level in the expansion tank.
more liquid is conveyed from the expansion vessel via the prechamber into the circulatory system than flows into the expansion vessel via the overflow valve.
the liquid level in the expansion vessel drops again. All of this happens practically without fluctuations in the operating pressure in the circulatory system.
the amount of water delivered by the pump determines the flow through the valve.
the pressure circuit does not have to be monitored.
a variant of the invention provides that the prechamber is essentially prismatic or cylindrical and is aligned vertically and that the inlet line opens into the prechamber above the outlet line.
An advantageous embodiment of the invention provides that a lock is arranged between the prechamber and the expansion vessel, the lock being formed by a diaphragm valve.
the lock prevents or hinders the creation of an undesirable circuit between the prechamber and the expansion vessel, in which the warm water flows from the prechamber into the expansion vessel and at the same time cold water from the expansion vessel into the prechamber.
Another embodiment of the invention provides that the feed line ends with a vertically upwardly directed nozzle, which is located within the prechamber.
Fig. 1 shows the diagram of a device according to the invention for a heating system
Fig. 2 shows a plan view of a lock
Fig. 3 shows a variant of the prechamber.
the circulation system of the heating system consists of: the boiler 1, the liquid line 2 (flow) or 2 '(return) and radiators (e.g. radiators) 3.
the liquid circuit is maintained (or supported) by a system circulation pump 25 ).
Filtered and softened tap water is preferably used as the heating or circulating liquid.
the inlet pipe connections 5 and the discharge line 6 in the flow line 2 can be arranged relatively close behind the boiler 1 in order to use the thermal degassing.
connection is particularly suitable for water temperatures up to approx. 90 ° C. At higher operating temperatures, the inlet line 5 and the outlet line 6 are better connected in the return line 2 '.
the overflow valve 7 is located in the feed line 5 and can be adjusted to the system pressure.
the actual pressure of the heating system can be read from a manometer 8. In heating systems, there is usually an excess pressure of at least 1.5 bar (depending on the height of the building) in the liquid circulation system.
a continuously operating pressure and circulation pump 9 is located in the discharge line 6.
a check 11 is also provided in the discharge line 6.
the expansion vessel 4 there is a lower level regulator 12 for the fresh water make-up and an upper level regulator 13 for securing the outlet of the expansion vessel 4.
Line 19 is an inlet line for fresh water. Fresh water is let into the expansion vessel 4 when the water level 14 falls below the level of the lower level regulator 12.
the fresh water supply line 19 is provided with a solenoid valve 22.
a prechamber 10 is arranged between the expansion valve 4 and the inlet and outlet lines 5, 6. The pre-chamber 10 is located below the expansion vessel 4 and is connected to it via a single line 15.
the prechamber 10 is a vertically arranged cylinder, the inlet line 5 opening into the prechamber above the outlet line 6.
a lock 17 which is formed by a membrane valve.
the lock 17 is provided with a cross-shaped slot 18, so that tabs 20 are formed.
the tap water from the heating circuit passes through the feed line 5 and the nozzle 16 into the prechamber 10, where it releases gas due to the lower pressure.
the barrier 17 prevents the warm water from rising immediately upwards into the expansion vessel 4 and cold water from flowing back. A large part of the water is thus sucked in by the pump 9 and conveyed directly back into the drain line 6 without getting into the expansion vessel 4.
the inlet line 5 ends with a vertical nozzle 16 which is arranged inside the prechamber 10 and is directed upwards.
An air collecting pot 23 is also provided in the feed line 5.
the reference 21 denotes the electrical control.
the degassing of the tap water can take place both continuously and cyclically.
