Definitions

  • the invention relates to a device for releasing a fluid flow in a line system, the line system having a resting pressure which is greater than the flow pressure.
  • the invention is described below in its application as a toilet flush.
  • a flushing cistern Two systems are known in the prior art for flushing toilets, namely a flushing cistern and a flushing system.
  • the advantage of a cistern is that the flow pressure of the pipe system may well be low and the pipe cross-sections do not have to be large, but a sufficient amount of water with sufficient flow pressure is available for flushing.
  • a certain disadvantage of cisterns is their complicated structure and in particular that complex inlet valve and the not inconsiderable space requirement. Another disadvantage is that, because of the filling time, two rinsing processes cannot be carried out in quick succession.
  • the invention is based on the object of providing a device for releasing a fluid flow in a line system, that is to say a flushing system, which / despite a flow pressure of the line system, which is significantly lower than the line system idle pressure, is always adequate with minimum space requirement Amount of rinsing liquid available.
  • the invention proposes a device for releasing a fluid flow in a line system, which has a static pressure and a flow pressure which is lower than the static pressure, the device being provided with a release valve with an inlet opening and an outlet opening, a connecting line piece which has a passage channel with an inlet opening and an outlet opening and an opening line which opens into an opening opening of the through channel, the outlet opening of the connecting line piece being connected to the inlet opening of the release valve, the opening line being connectable to the line system and the outlet line opens at an acute angle in the direction of the outlet opening of the connecting line piece into its passage, and a pressure accumulator for the fluid, which has a fluid receiving volume connected to the inlet opening of the connecting channel piece, into which fluid from the connecting line piece up to when the release valve is closed Reaches the static pressure of the line system and flows out of the fluid to the connecting piece when the release valve is open.
  • the device according to the invention is provided with a release valve which has an inlet and an outlet opening.
  • This release valve is operated manually or by motor to let the fluid flow out.
  • the inlet opening of the release valve is connected via a connecting line piece to a pressure accumulator for the fluid to be released.
  • the connecting piece has a passage with a. Inlet and an outlet opening.
  • a junction line opens into the passage channel and can be connected to the line system.
  • the connecting line piece is designed in the manner of a T or Y connecting line piece, wherein according to the invention the junction line runs at an acute angle to the essentially straight passage channel and opens into it. In this case, the confluence line extends in the direction of the outlet opening of the passage channel connected to the release valve.
  • the pressure accumulator When the release valve is shut off, the pressure accumulator is in fluid communication with the line system. In the unfilled state, the pressure accumulator is depressurized, so that fluid flows into the pressure accumulator due to the flow pressure of the line system. This process ends at the moment when the pressure in the pressure accumulator is equal to the resting pressure of the line system. Now the pressure accumulator is filled with fluid at rest pressure. If the release valve is now actuated, fluid flows both from the pressure accumulator through the passage channel of the release valve and fluid from the line system via the junction line through the passage channel and the release valve.
  • the device according to the invention thus uses the advantages of a cistern system, namely small feed cross-sections and low noise, without taking over the disadvantages of this system, namely a complicated structure, large space requirements and waiting for a sometimes not inconsiderable time to trigger the next flushing process. Because the pressure accumulator, which is quite small in volume, is refilled relatively quickly, so that a quantity of flushing fluid is almost always available.
  • junction opening of the junction line in the passage channel of the connecting line piece is to be interpreted from a fluidic point of view, so that fluid is "carried away" from the line system by the fluid flow from the pressure accumulator.
  • the Venturi effect is expediently used here.
  • the opening should expediently extend over a large distance in the axial direction of the passage, which increases the fluid entrainment effect.
  • the cross-section of the passage channel should be larger than that of the junction line (ratio of the passage channel cross-section to the junction line cross-section between 2: 1 to 5: 1).
  • the flow rate of the fluid flowing out of the pressure accumulator is also decisive for the fluid entrainment effect.
  • This flow rate is determined on the one hand by the pressure in the pressure accumulator and on the other hand by the flow cross section of the passage channel. It is expedient if the passage channel - viewed in the direction of flow - is narrowed in front of the opening, which can be achieved by using an orifice or by appropriately designing the passage channel. It is also expedient here if this constriction position is eccentric and the inner projection defining the constriction point is arranged in the passage channel, in particular in the region opposite the inlet opening. This ensures that the fluid flow runs directly along the opening or that the highest flow speeds are achieved there.
  • pressure accumulators systems such as are known from pressure compensation vessels in sanitary and heating systems are particularly suitable as pressure accumulators.
  • diaphragm pressure accumulator which has an elastic diaphragm which is arranged in a rigid container. This membrane divides the container into a fluid holding volume and into a further (counter pressure generating) volume, which can be air or

  • the membrane expands until a counter pressure equal to the static pressure of the line system is built up in the second volume.
  • the size of the fluid holding volume ie the degree of expansion of the membrane, can be adjusted by means of a filling or adjusting valve.
  • the container can also have a pressure relief valve.

  • a membrane pressure accumulator for example, a container in which a wall is arranged in a sealing and displaceable manner is suitable.
