Definitions

  • the invention relates to a method and system for water pressure regulation or control in a pressure zone as well as apparatus for carrying out and operating the same.
  • a supply pressure for a firefighting hydrant in the 40th floor is provided at a height of 120 m
  • the maximum flow pressure in the underground car park - eg for reasons of safety at work eg for the fire fighters
  • the pressure of 80 MPa (8 bar) was set as the maximum acceptable limit for the firefighter.
  • pressure reducers were often used in the past, although they had been relegated for years normatively (DIN 1988) from extinguishing water systems
  • the first type of the prior art requires - due to the provision of multiple risers and booster pumps - a high material and technical effort, if predetermined maximum pressures are not to be exceeded, which makes such versions very expensive.
  • the second type is that the pressure regulator and / or pressure reducing valves are very sensitive and therefore can jeopardize the water supply. Their use in extinguishing water is therefore very controversial and should be avoided (see also DIN 1988).
  • the pump must generate a supply pressure of eg 15 bar in order to achieve the required 4.5 bar on the 30th floor. If, on the other hand, a hydrant is actuated in the underground car park, the pump merely has to produce a supply pressure of, for example, 5 bar in order to achieve the same flow pressure there.
  • the corresponding values are stored and in case of a trip on a certain floor, they only have to be requested for this floor. Practically, this is realized, for example, by means of variable-speed pumps, for example pumps with a frequency-controlled three-phase drive.
  • the new supply pressure is set to the value which is most permissible for this further removal station.
  • the setting of the new supply pressure is thus carried out in this case, approximately at the lowest for the removal station at which an error is detected, the maximum allowable supply pressure setpoint. So if a fault in the 50th floor, then in the 4th floor and then in the 3rd-th floor - each without prior detection of any water withdrawal in any floor - detected, and is the desired flow pressure in each floor 4.5 bar, the supply pressure according to the invention is adjusted so that it on the 3rd-th floor a flow pressure of 4.5 bar - and on the floors above correspondingly less - results.
  • a predictive water pressure setting due to fault detection ensures the method of the present invention by the water pressure for the water sampling is set here, which corresponds to the first detected error, since it is assumed that there - or at least close to it - a possible source of fire and here most likely with a subsequent firefighting, ie Water withdrawal is expected.
  • the speed specification for the pump drive can be carried out so that the characteristic of the pump - stored for example in the memory of a computer system used for carrying out the method according to the invention - and thus the associated speed is determined for each supply nominal pressure.
  • the supply pressure ie the pressure generated by the pump in the pressure zone
  • the supply pressure can also be measured by means of a pressure sensor and approximately the speed setpoint of the pump drive can be used as a control variable for the water pressure to be set.
  • the adjustment of the supply pressure is not only based on the geodetic height, but also in dependence on pipe friction losses, which can be done for example by appropriate calibration of the water distribution system and taking into account the values found in the stored for each floor supply pressure values.
  • the detection of water removal at one of the water removal stations can be done in different ways, such as by means of a measuring element that triggers a manual tapping a water tap or by a measuring element that triggers when reaching and / or exceeding a certain water volume flow. Also, the detection of a fault at the water removal station, ie from the water sampling station associated respective measuring element, so as one of a short circuit or cable break can be done so, such as through the use of openers, instead of closer.
  • the speed control or speed control of the pump (more precisely, the pump drive), as conventionally, by means of a regulated - preferably brushless - DC drive drive as a pump drive.
  • a frequency-controlled three-phase drive as a pump drive.
  • the adjustment of the supply pressure in the event that this should be a pressure reduction (at least) done by an actuator or control element, preferably a water drain valve opened as long or a pressure reduction pump is operated for pressure reduction until the new supply pressure is reached or fallen below.
  • the supply pressure is set to the desired value which corresponds to the maximum permissible supply pressure of all sampling stations in the pressure zone (FIG. thus usually the highest permissible supply pressure for the highest located sampling station).
  • the supply pressure in the pressure zone will be 20.5 bar after the detection of all detections on all floors - fault detections as well as water withdrawal detections Ready pressure set so that in the worst case, so as a fire in the 20th-th floor there is immediately sufficient flow pressure at the sampling point available.
  • the method according to the invention described here can become problematic in cases in which a particularly long riser pipe is used, for example in large skyscrapers, since the pressure then prevailing in the riser becomes quite high as a result of the water column for the parts of the pipe lying further down. In this case, it is then difficult to quickly provide by means of a drain valve for the required to achieve the highest permissible flow pressure pressure reduction of the supply pressure in the pipe, since the degradation of the water column in any case, when using drain valves that are reasonably cost-effective - may take a while, which may be too long for the lower sections. In conventional systems, which work with multiple pressure zones, this problem does not occur in principle, since here a division of the building into different pressure zones takes place, the individual risers are limited in each case from the height.
  • a pressure reducing device for carrying out the method according to the invention, which is designed so that a water supply pipe, so as the riser at least one check valve which opens in upward flow direction of the water from the water pressure source to the water outlet point and in Turning direction thereby almost only closes because it has an opening which is designed so that the water can thereby pass through in the opposite direction to the aforementioned flow direction due to gravity, so as to - seen in the upflow direction - behind the check valve region of the water supply pipe when closing the check valve free from the pressure that goes beyond the pressure caused by gravity pressure.
  • a small, preferably round hole in the valve of preferably not more than 10 mm, more preferably not more than 5 mm diameter, that serves for a gravity caused by the return flow of water for the purpose of very rapid pressure reduction.
  • the opening is not configured as a round hole, that is to say as a bore, instead of the opening size in the form of a diameter specification, a (approximately) corresponding surface area of the opening cross section of another geometry corresponding to the round hole occurs.
  • a plurality of spaced non-return valves of this type according to the invention may be provided which limit the pressure caused by the liquid column standing in the pipe pressure in their respective section, since they each only a small opening in the direction of the Gravity generated (return) flow.
  • the pressure reducing device according to the invention described here is not only for use with the invention described here Method and its devices can be carried out, but also independently thereof is an independent invention for pressure reduction in pipes carrying liquids, in particular risers, as it alone or in the tube in series successively spaced a rapid pressure reduction even without a high outflow volume of the liquid, preferably of water, in the pipe.
  • the above-described inventive method for water pressure regulation or control in a pressure zone can be operated in all embodiments on a suitably equipped computer system, the computer preferably interfaces for controlling the actuators - here about speed setpoint for the pump drive - and / or to read the measured values or Stati of sensors - here measuring elements such as pressure sensor (s), water flow meter or exhaust valve sensor (s) - has.
  • the method according to the invention can also be present as a computer program, for example on a data carrier or an electronic carrier signal, for example for download.
  • a water pressure regulation or control system for water pressure regulation or control of a pressure zone can be constructed, namely such that a computer system has that as described above is arranged and also provides detectors for detecting a respective water extraction or a fault at a removal station, which are connected via the interface to the terminal for one or more detectors to the computer system.
  • a pump which supplies the extraction stations with water and having a pump drive whose speed can be specified via the interface for outputting the speed setpoint, wherein the computer system is connected via the interface for outputting the speed setpoint with the pump drive ,
  • the system according to the invention preferably also has a pressure sensor which measures the respective supply pressure (also called pump pressure), that is to say the operating pressure produced by the pump in the pressure zone.
  • the water pressure regulation or control system according to the invention is preferably used for water pressure regulation or control of the service and / or drinking water supply in a high-rise, ie preferably in a house, where the floor of at least one lounge over 22 m above the surrounding (the skyscraper surrounding) terrain surface.
  • the skyscraper particularly preferably only a single pressure zone for the respective supply, so only a single riser for the service water supply and / or a single riser for the drinking water supply.
  • the system according to the invention (as well as the inventive method) can also be used in (very large) buildings having multiple pressure zones, for example, if the building is too large for a single pressure zone, ie the distance between two floors, which must be supplied in parallel to each other, without the pressure at the removal point in the lower floor is too high, is too large.
  • the present invention allows namely a reduction in the number of pressure zones, since it allows them to be sized so large that two different floors can be just in parallel supplied to each other without the pressure on the lower floor at the sampling point high or the pressure on the higher floor becomes too low.
  • the use of the present invention as a water pressure regulation or control system for the extinguishing water supply, preferably in a high-rise building.
  • the fire water network of the skyscraper can have only a single pressure zone. If it is still too large, the present invention can also be used in this case of use at least to reduce the number of pressure zones, as has already been explained above to the case of use for the service and / or drinking water supply.
