Definitions

  • the invention relates to a water supply system, in particular for catering wagons of passenger trains, consisting essentially of at least one water tank, a circulation circuit formed by pipes and / or hoses, which contains a circulation pump and a UV disinfection device, and one to the points of use - such as a tap, dishwasher - leading pressure line.
  • a water supply system with the aforementioned generic features belongs to the state of the art due to the obvious prior use of so-called bistro service cars from InterRegio passenger trains of the Deutsche Bundesbahn.
  • the non-self-priming circulation pump conveys the entire water content of the system through the UV disinfection device.
  • a second pressure booster pump which does not run continuously, taps the circulation circuit behind the UV disinfection device and generates pressurized water for feeding the consumption points.
  • the booster pump is controlled by a pressure switch, i. that is, it starts pumping as soon as the pressure in the pressure line drops below a certain value.
  • the invention has for its object to design a water supply system of the generic type so that the simplest possible structure can be realized with a smaller number of components.
  • a circulation pump designed as a self-priming centrifugal pump is used in addition to its circulating function as a pressure booster and feed pump for the pressure line.
  • one embodiment of the invention is that the water pressure within the pressure line can be adjusted by means of a throttle or a regulating valve, the throttle or the regulating valve being assigned to the circulation circuit.
  • the invention advantageously provides a water supply system which works with only a single centrifugal pump, air possibly flowing into this system being reliably displaced due to the self-priming pump.
  • a water tank 1 which can optionally be communicatively coupled to a further one or more water tanks, is connected to a filling pipe 7, which has a filler neck 7a accessible from the outside of the car 8.
  • the water tank 1 contains a heating insert 9 and a switch 10, which protects a self-priming centrifugal pump 3 with an electric motor from running dry.
  • a shut-off valve 11, a non-return valve 12, a UV disinfection device 4, a fixed or adjustable throttle 6 and a solenoid valve 13 are arranged.
  • the pipeline 2a with its hose pieces 2a ' is at the same time part of the pressure line 5, which branches off in front of the throttle 6 and leads to the consumption points of the catering vehicle.
  • the pressure line 5, which is also provided with a non-return valve 12, has a membrane pressure vessel 14, a pipe vent 15 and a pressure switch 16.
  • the centrifugal pump 3 which in this case works as a pure circulation pump, conveys the water continuously from the container 1 through the UV disinfection device 4 back into the container 1. This occurs in the circulation circuit 2 pressure P defined by throttle 6, to which a delivery quantity Q corresponding to the pump characteristic belongs.
  • the pressure P also prevailing in the pressure line 5 is available at the consumption points as the required water form.
  • An overpressure switch 17 which interacts with the pump 3 serves to protect the system.
  • the removal of a smaller amount of water is compensated for by the diaphragm pressure container 14 or taken from the circulation circuit 2 with a simultaneously falling pressure P and an increasing delivery rate Q in accordance with the pump characteristic. With greater water withdrawal, the pressure P drops to a certain lower line pressure. Then the solenoid valve 13 of the circulation circuit 2 controlled by the pressure switch 16 is closed, so that the centrifugal pump 3 can convey the entire amount of water into the pressure line 5 to the consumption points.
