Definitions

  • the invention relates to a valve assembly for arrangement in the Water supply line of a water drain fitting, including one Water inlet, a water outlet, an electrically operated water valve as well a sensor and control device for the automatic actuation of the Water valve.
  • valve assemblies are well known in the prior art and widely used in practice. They are particularly related to Non-contact fittings such as urinal or Toilet flushing used, where the electrically controlled water valve is controlled by means of an electronic sensor and control device in order to thus switching water flows on and off as required.
  • Sensors are, for example, infrared or ultrasonic sensors.
  • non-contact valves are controlled in that germs and bacteria of one user are not passed on to another user transmitted through the use of a manually operated flushing device can be.
  • the non-contact water drain fittings allow that after using the equipment, e.g. B. of WCs, the sink or the urinal, the water valve opens automatically and thus a rinse is triggered. Closes at the end of the rinsing process the water valve automatically again and the one flowing into the equipment Water flow is switched off.
  • the use made of the toilet or urinal is detected.
  • An electronic control device evaluates the usage detected by the sensor and controls accordingly electromagnetic water valve. This opens due to the activation the control device for a certain time, for example six seconds, and thereby gives a flow of water for flushing the toilet or urinal free.
  • a certain amount of water is flushed through the toilet or during the flushing period passed the urinal, whereby according to the technical standard the amount of flushing water defined by the unit of time, d. H. the longer the rinsing time, the greater the amount of flushed water.
  • time-dependent water flushing is the fact that the Amount of water that is within a given, non-variable Time window is given, primarily as a function of water pressure represents. The result of this is that despite the constant rinsing time, they differ from one another different flush volumes due to different water pressure can adjust. In extreme cases, this can disadvantageously lead to the fact that despite a sufficiently selected rinsing time interval for a rinsing process provided amount of water is too small and residues in the toilet or in Urinal remain. On the other hand, the one released for rinsing Amount of water should also be so large that much more rinse water in it Toilet or headed into the urinal than for carrying out a proper flushing would be required.
  • the invention is therefore based on the object , while avoiding the disadvantages mentioned above, to further develop a valve assembly with an integrated water valve in such a way that, while at the same time being easy to install, a defined, consistent, faultless washing result is ensured.
  • the core idea of the teaching according to the invention is therefore a valve assembly which in addition to the generic known components also about a integrated pressure reducing valve.
  • This pressure reducing valve is in Flow direction of the water supply line electrically operable water valve upstream, whereby it is achieved that on Water valve always has the same water pressure.
  • this ensures that at a predetermined opening time of Water valve, d. H. a predetermined flushing time, always the same amount Water passes the water valve and is flushed into the toilet or urinal becomes. In this way it is achieved that regardless of possible Pressure fluctuations in different operating systems and the same Valve assembly with factory set flushing times always the same Delivers washing results.
  • the valve assembly according to the invention is advantageously compact trained and easy to use. It is also already existing by the fitter Water supply lines of a water drain fitting in a simple way integrated. Both the pressure reducing valve and the are ex works Water valve preset. Such a preset can, for example be such that the pressure reducing valve to an output pressure of 3 bar is preset. The water valve is set accordingly at the factory, see above that for a given inlet pressure of 3 bar the opening time of the valve in such a way is chosen that the amount of water dispensed within the opening time is sufficient to get a satisfactory and flawless rinse perform. One equipped with such preset valves The valve assembly can then be assembled by the installer without readjustment become. It should only be noted that the inlet pressure of the pressure reducing valve is greater than the factory-set outlet pressure.
  • valve assembly according to the invention is advantageous ensured that regardless of those in the water supply line prevailing pressure conditions always the same pressure on the electrical actuated water valve is present, so that at a factory preset The opening time of the water valve for flushing is always the same amount of rinse water flows through the water and therefore enters defines consistently good washing results.
  • the valve assembly according to the invention also has further advantages. So it occurs, for example, with conventional water valves from one Water pressure of over 7 bar to disturb disturbing flow noises. Also the The speed of the closing process at such a high pressure is disadvantageous changed. This is made more advantageous by the valve assembly according to the invention This prevents the upstream of the water valve Pressure reducing valve ensures that there is always water pressure on the water valve is present, which is below the preset pressure, for example below 7 bar.
  • the outlet pressure of the pressure reducing valve is preferably continuously adjustable. Such a setting is made at the factory, so that on-site adjustment by the installer is no longer required. So on the one hand, constant water flushing quantities can be ensured, on the other hand, a time-consuming and costly on-site adjustment by the Plumber.
  • the Pressure reducing valve has a spring working against the water pressure, the Bias to adjust the outlet pressure is adjustable. This will an easy to carry out and at the same time very precise possibility of Setting provided. This type of pressure adjustment also enables a readjustment. For example, in the event that the factory set outlet pressure of the pressure reducing valve should be greater than that on Pressure reducing valve actually present input pressure, by the installer Readjustment can be made. However, this is only in exceptional cases required.
  • the pressure reducing valve is in Pressure flow direction upstream of the supply line, a water filter. This serves to pre-filter the water flowing into the pressure reducing valve to block the pressure reducing valve due to water in the water To prevent particles.
  • the filter is advantageously accessible from the outside and can be cleaned if necessary.
  • the water valve is in Flow direction downstream of the water supply line Power generation unit provided. This is used for an actuation of the electric water valve to generate electricity and to the Deliver water valve.
  • the power generation unit preferably consists of a water turbine integrated in the water pipe and one to the Water turbine connected generator for electrical power generation.
  • a storage unit is provided. Preferably is such a storage unit a rechargeable capacitor or a rechargeable battery.
  • the pressure reducing valve and the water valve connected in series formed in one piece, so that the Overall valve assembly is compact and therefore easy to use and to be assembled.
  • the optional components of the valve assembly such as. B. Combine filter, power generation unit and storage unit integrally, see above that even when using a comprehensive all optional components Valve assembly ensures a compact structure and the whole Valve assembly advantageously as a single element assembly in as well existing water supply lines can be used. This will also achieved the advantage of being independent of possibly existing ones Pipes already integrated pressure reducers on every water drain fitting a constant washing result is achieved. To be carried out on site Attitudes, especially attitudes to the coordination of different System components on top of each other, are with the invention Valve assembly avoided in an advantageous manner.
