Definitions

  • the invention relates to a system for feeding water into a container for supplying an extinguishing water consumer from a drinking water pipeline via a free outlet.
  • the plant is everywhere applicable where a water, especially a fire water consumer is present, the water in a container such as an intermediate container is available and the intermediate container with water from the public water supply or the domestic water supply of a building, especially from a Drinking water pipeline to be fed and refilled.
  • connection lines to the make-up valve In order to prevent stagnant water, connection lines to the make-up valve must be flushed regularly in accordance with the generally accepted rules of technology. Usually, self-acting purging devices are installed for this purpose, which ensure the required regular water exchange in the connection lines.
  • Containers such as reservoirs or lines for extinguishing water, for example for extinguishing nozzles of extinguishing systems in a building must have sufficient extinguishing agents such as extinguishing water available.
  • extinguishing agent container is always filled with extinguishing agent and, in the event of fire, is fed with further extinguishing agent, such as water.
  • the extinguishing water is derived from a domestic water supply or a public water supply network, no water from tap water or containers with stagnant water in the public water network or the domestic water network, especially in drinking water pipelines must flow back so that the quality of the drinking water is not affected.
  • DE600 20 519T2 describes a parallel-fed integrated non-stagnant water supply network for domestic water and sprinkler systems, in which a storage tank is arranged, the stagnation of water being prevented by supplying both the individual consumers of the house and the sprinkler system directly from the drinking water line, including are provided on the drinking water pipe multiport connections, so that a backflow of the domestic water in the drinking water pipe is not possible.
  • DE27 47 941A1 describes a drinking water pipe from which a hot water circuit is diverted and prevent a piston separation pipe and pressure control valve that hot water flows back from the hot water circuit in the drinking water pipe, with a three-way valve is arranged.
  • This electromagnetic three-way valve partially connects the drinking water line with a pressure and discharge line. A reservoir for extinguishing water was not described in this document.
  • DE10 2006 028 151A1 describes a method for drinking, operating and / or extinguishing water supply and drinking, operating and / or extinguishing water pipes with a reservoir containing a baffle plate.
  • the solution provides that drinking water is introduced into a storage tank and removed as needed via a water pressure line and that a pressure drop in the pipe network is inevitably generated by opening an actuator.
  • the document specifies a possibility to meet the respective requirements with regard to the operation of a domestic water supply.
  • DE100 35 889A1 describes a device for fresh water supply, in which a container for fresh water and a container for service water are arranged, each container having a float and a valve and a three-way valve is arranged in the inlet of the process water tank in front of a conveyor.
  • the proposed solution meets the legal requirements, however, requires a considerable costly equipment expenditure.
  • this device allows no priority filling of the container in case of need by throttling or blocking the water supply to other consumers.
  • DE39 11 747C2 describes a device for regulating the water supply from a reservoir of a fire extinguishing system in which the level of the water level in the container is determined by means of floats, wherein a rod between the float and valve is arranged, which allows a uniform control of the valve and thus the water outlet.
  • GB2 280 369A discloses a sprinkler system with a system for supplying a fire water consumer.
  • This system for supplying an extinguishing water consumer comprises a feed tank and a water supply line, which is provided exclusively for supplying water to the sprinkler system and has a float-controlled valve for filling the feed tank.
  • the document DE 10 2009 056 452 A discloses an extinguishing water system with a reservoir (water reservoir), which is filled via a free outlet from a drinking water pipe.
  • a disadvantage of the existing state of the art is that the existing systems for supplying a consumer such as an extinguishing water consumer from a drinking water pipeline of a building or the public water supply require considerable effort to meet the normative requirements. This concerns the technically complex barrier and the devices for flushing. Furthermore, the systems are not always suitable, nachzuspeisen from the pipeline network of the building or from the public pipeline network for water supply demand-controlled water in sufficient quantity in the container. In particular, these systems and devices do not allow priority or exclusive supply of fire water consumers through a container which is filled by blocking or throttling the water supply to all other consumers on the pipeline or the pipe network primarily via a valve which simultaneously performs this shut-off or throttling.
  • a system for feeding water into a container according to the features of the first claim.
  • the system can also be designed as a device.
  • the solution according to the invention provides for a cost-effective and reliable system for the demand-controlled supply of water into a container for supplying an extinguishing water consumer from a drinking water pipeline via a free outlet.
  • This container serves as a buffer and supplies a fire water consumer.
  • the container does not have an immediate fluid connection to the drinking water pipeline, i. no direct connection, so that no water from the container, which is stagnant after a long time, contaminated water, can not get into the drinking water pipeline either by sucking back or by opening valves.
  • the only connection of the container to the supplying pipeline network or drinking water pipeline is the air gap, the free fall distance of the free outlet for filling the container.
  • the term domestic water is also used for drinking water.
  • Household water consumers are thus drinking water consumers, if the pipeline network for domestic water leads drinking water.
  • the drinking water pipeline is part of the drinking water pipeline network, which may also be pronounced as a pipeline network for domestic water.
  • the term drinking water pipeline can be used as a synonym for the pipeline network for domestic water.
  • a valve preferably a multi-way valve is arranged in the drinking water pipeline, preferably the domestic water supply, which completely or partially releases the path of the water via a free outlet into the container in the one switching position or in a circuit area and thereby the flow of water in the Drinking water pipeline in the direction of domestic water consumers in the flow direction after the valve blocks or partially blocks and locks in the other switching position or the other switch position range the way of water in the container or throttles the inflowing amount of water and thereby the way of the water in the drinking water pipeline towards domestic water consumers completely or partially releases.
  • the feed into the container takes place depending on the level of the water level in the container.
  • the container has a float for determining the level of the water level in the container, wherein the multi-way valve and the float are designed so that the float directly actuates the multi-way valve, and thus the switching position of the multi-way valve from the level of the water level in the container depends.
  • valve is placed directly after the connection to the public water supply in the piping network as the first consumer, so that the container and the fire water consumer in case of need, the first and only water consumer.
  • a suitable level measuring device e.g. a sensor, float switch or float arranged, which determines the level of the liquid in the container and the valve, preferably the multi-way valve in a suitable manner.
  • the valve is then adjusted as long and to the extent required by the level in the tank. This ensures that the intermediate container always has a predetermined water level.
  • the valve control can be mechanical, electrical, pneumatic and hydraulic, wherein the valve can be controlled directly or indirectly.
  • the free outlet may be located between the outlet of the valve and the water surface.
  • a pipe, a gutter or another suitable means for discharging the water can also be arranged between the valve and the free outlet.
  • the reservoir for the extinguishing water can be made of metal, plastic or other suitable material and is designed so that it contains a fire-extinguishing volume, which is sufficient for a part of the extinguishing process. It may be a closed container in a frost protected location. If no frost-protected place is available, the container should be insulated or heated accordingly. At the lowest point of the container, a drain valve for discharging the extinguishing agent is arranged. At the highest point, as far as it is a closed container, a device for ventilation and be provided.
  • a multi-way valve as a valve in the drinking water pipeline.
  • Particularly suitable is a 3/2-way valve with overlap, so that a continuous control with intermediate positions is possible.
  • switch positions or switch position ranges can be set so that a completely blocked or partially throttled flow of water into the drinking water pipeline from the public water supply is possible, with simultaneous exclusive feed or partially throttled feeding of the water into the container. But it is also possible to block this feed completely or only partially.
  • shut-off valves may be, for example, butterfly valves, which are connected in opposition, so that they can be opened or closed continuously.
  • a float is suitable.
  • This float can actuate the valve directly.
  • Another possibility is to transmit a signal electronically to the valve control.
  • a mechanical transmission for example by means of linkage.
  • a transmission such as a reduction gear can be arranged between the linkage and the valve.
  • Conceivable are other suitable gear or linkage.
  • Another way to measure the level of the water level in the container can be done by means of pilot valve, in which case a hydraulically acting valve is present, which adjusts the above-mentioned switching positions or switching ranges.
  • valve in this context of the design of the valve, it is possible to form the valve as a motor slide or as a solenoid valve. Also conceivable are pneumatically actuated butterfly valves with pneumatic actuators or self-medium-controlled valves, which are controlled by pilot valves.
  • Another object of the invention is a device for demand-controlled water supply for extinguishing water consumers with feeding water into a container for supplying a fire water consumer from a drinking water pipeline via a free outlet, wherein the container has no immediate fluid connection to the drinking water pipeline.
  • the device is characterized in that a multi-way valve is arranged in the drinking water pipeline, which completely or partially releases the path of the water into the container in the one switching position or in a switching position range and thereby the flow of water in the drinking water pipeline in the direction of domestic water consumers (12). locks or partially blocks and locks in the other switching position or the other switch position range the way of water in the container or throttles the inflowing amount of water and thereby completely or partially releases the path of the water in the drinking water pipeline towards domestic water consumers.
  • the container has a float for determining the level of the water level.
  • the multi-way valve and the float are designed so that the float directly actuates the multi-way valve, and thus the switching position of the multi-way valve depends on the level of the water level in the container.

  • the solution according to the invention has the advantage that with little technical effort, reliable and inexpensive water from the domestic water supply, if necessary and in required quantities via a container for supplying a fire water consumer is provided without water loss caused by forced flushing.
  • the proposed solution also makes it impossible for stagnant water to pass from the extinguishing agent container into the public water supply or into the drinking water pipeline of the building. Furthermore, the system ensures that when needed first or even exclusively the container is fed with the water, and that only when reached the predetermined level of water level in the container, the water flow in the drinking water pipeline towards home water consumers is fully released. This is necessary in particular for extinguishing water consumers.
  • the FIG. 1 shows the system for supplying an extinguishing water consumer 7 from a drinking water pipeline 6 for a domestic water supply between the inlet of the public Water supply 3 and the home water consumers 12 of the building or house, in which line 6, the multi-way valve 1 is arranged.

  • the container 5 Since the container 5 is filled only via the free outlet 2 and has no pipe connection to the drinking water pipe 6, the container 5 has no direct fluid connection with the drinking water pipe 6. Thus, a secure separation between the fresh water, usually drinking water, in the drinking water pipe 6 and the service water in the container 5 is guaranteed.
  • the water in the container 5 is after filling by prolonged standing in this container to stagnant water, to process water which is contaminated.
  • the level 11 of the water level in the container 5 is controlled by a sensor which is a float 8 with the linkage 9 to the transmission 10.
  • the float 8 actuates the multi-way valve (1) directly to the linkage 9 and the transmission 10, so that the switching position of the multi-way valve 1 from level 11 of the water level in the container 5 depends.
  • the measured level height can be mechanically converted into actuation paths for controlling the multi-way valve and the required switching positions or switching position ranges of the multi-way valve 1 can be realized.
  • a switching position or in a switching position range of the multi-way valve 1 is achieved, which is the path of the water from the drinking water pipe 6 via the pipe 15 to the free outlet and the free outlet 2 in the container. 5 completely or partially releases and thereby blocks or partially blocks the flow of water in the drinking water pipeline 6 of the domestic water supply in the direction of the domestic water consumers. This happens until the float 8 has reached a predetermined height and the multi-way valve 1 blocks the path of the water to the outlet 2 and no more water flows into the container 5. In this switching position, the multi-way valve 1 is the path of the water between the inlet from the public water supply 3 to the house water consumers 12 in the pipeline network 6 completely free.
