Definitions
- the invention relates to a central water supply in a main water supply line, from which several tapping points or consumers can be supplied with water, such as the main water supply line of a single or multi-family house, the main water supply line of an individual apartment or a single commercial enterprise or a
- Construction site water supply line Regular water withdrawal must be guaranteed for all withdrawal volumes and, at the same time, the unwanted water leakage at the withdrawal points and in the entire pipe system must be prevented.
- time unit of the maximum possible water leakage from a broken pipe or from an open tapping point is an unsuitable quantity, since depending on the pipe cross-section, degree of opening at the tapping point and water pressure, a different amount of water may have entered the affected building causing damage.
- a water flow sensor is arranged in the main water supply line.
- a water flow sensor is therefore installed at each tapping point and this is additionally coupled with a central water safety device in such a way that the central water safety device only opens when it is opened at a tapping point.
- This increases the cost factor mentioned above for the large number of decentralized water safety devices by the cost of coupling and controlling the individual water flow sensors, which, however, cannot act as decentralized water safety devices.
- An unintentional removal from one The tapping point for example by a hanging float valve in the cistern, is not prevented, however, because the respective flow sensor just causes the central water safety device to open, so that large quantities of water can escape from the tapping point causing damage. This means that the effect of the central water safety device is only restricted to leaks in the pipe system.
- the invention specified in the main claim is based on the problem of creating a central water safety device which, after the conscious or unconscious removal or leakage of a water volume limit set for the respective application, which from the insurer's point of view is still below the limit for causing damage for the respective application , blocks the main water supply and thus prevents further withdrawal.
- the advantages achieved by the invention are, in particular, that preventive water damage, both from device defects and from leaks in the piping system on buildings, can be avoided or severely limited by the maximum possible escape of a water volume that does not yet cause any or only minimal and limited damage, that large consumers, such as construction sites, can be protected against unwanted water leakage of any kind, leaks, external withdrawal, misconduct, etc.
- Device that can be operated by the consumer group is offered without complicated programming processes to be carried out by the user. Furthermore, natural resources are conserved.
- a further advantageous embodiment of the invention is specified in claim 3.
- This further development of the volume determination as a manually adjustable device with a forced reset to the originally defined volume limit makes it possible to implement a switchover for a one-time or temporary, larger consumption.
- a battery part is arranged for removal points that cannot be connected to the public power supply, in particular construction sites. The field of application of the invention is thus easily expanded.
- a similar further advantageous embodiment of the invention is specified in claim 4.
- This training enables a time-limited unlimited water withdrawal with a forced reset according to the above time limit or a water withdrawal to the originally defined volume limit.
- a battery part is provided for locations remote from the public power supply.
- a further advantageous embodiment of the invention is specified in claim 5. This further development enables a cost-effective solution for new installations, since the combination of water meter and water safety device lowers the installation costs and the manufacturing costs of the combination device are reduced compared to the two individual devices.
- a further advantageous embodiment of the invention is specified in claim 6. This further training enables the setting of volume limits for the various applications, their lowering during night operation and the total blockage of the main water supply in times of no need.
- a further advantageous embodiment of the invention is specified in claim 7.
- This development enables the use of other control variables already present in the respective domestic water system for the invention. It simplifies and expands the application options for water systems that are not fed by the public network, in particular rainwater harvesting systems or wells.
- a volume limit is selected that corresponds to both natural use and significantly minimizes or avoids the event of damage in the event of an unwanted exit.
- care must be taken for deliberate removal of larger volumes so that they cannot lead to uncontrolled water leakage after removal.
- a central water safety device is installed immediately after the water meter on the consumer side in a main water supply line of a family house. This installation can be carried out by any specialist company at low cost.
- the house network supplies the necessary electrical energy.
- the volume meter is preferably set to 45 liters by the installation company for a family home with a central water supply and cannot be adjusted by the operator.
- the volume counter compares each withdrawn water quantity with the set volume limit and reacts when the volume limit is reached by blocking the main water supply via the existing shut-off device. Unlocking is only possible manually at the central water safety device, which is intended to ensure that the operator researches the cause beforehand. If, on the other hand, the set volume limit is not reached by the amount of water withdrawn, the volume counter resets as if no water had been withdrawn and is available for another withdrawal without a residual value.
- Time unit such as for bath filling 0.5
- this reset time can also be designed depending on the "excess” amount. On the other hand, it is also possible to only allow one withdrawal when switching to "Uber” quantity extraction and then to reset it regardless of the time.
- Period of time for concrete work larger amounts of water than usual are required.
- the forced reset over time is particularly advantageous here. Furthermore, is for use in places not connected to the public power grid
- the specified volume limit can be reduced to 5 liters.
- ON / OFF switching is expected in times of non-use, such as
- Drinking water feed 100 liters for construction sites and similar commercial operations, 5 liters as night reduction for all applications.
- a special case is the use of wells or rainwater storage tanks.
- a pressure vessel In a domestic water system, a pressure vessel is fed up to a regulated pressure level via an electrically operated pump. For this reason, the power consumption of the pump motor is compared with the specified volume limit as a control variable. All other variants, such as "overflow”, day / night switching and ON / OFF switching are possible with the same effect.
