Definitions

  • the invention relates to a flow rate limiter with a flow body, wherein the flow body is penetrated by at least one of a fluid flow-through channel with an inlet opening and an outlet opening and at least one gas channel with a gas suction and a gas outlet opening for a to be mixed with the leaving the channel fluid to be mixed gas is provided and connects to the inlet opening an inlet funnel.
  • the invention relates to a receptacle for limiting the flow rate with an inlet opening and an outlet opening for at least one fluid, wherein the inlet opening has a larger cross-section than the outlet opening.
  • the invention relates to a method for mixing at least one fluid with at least one gas, including water and air.
  • Flow rate limiter of the type mentioned are, for example, from the DE 100 08 438 A1 , of the EP 0 856 691 A or the US 5,11,994 known.
  • the DE 100 08 438 A1 relates to a ventilation device, with which the water can optionally be admixed with air, wherein the aeration device is arranged upstream between a water fitting and a connection piece of the supply line.
  • the EP 0 856 691 A discloses a water-saving valve for mixing water with air.
  • the US 5,11,994 describes a device for increasing the flow energy of water in a shower head with an air inlet for ambient air, a water channel for receiving water from a water supply source and at least one mixing chamber, which is in fluid communication with the water channel and the air inlet opening to receive water and air.
  • the DE 36 04 267 A1 relates to a recording for flow rate limitation, wherein the flow reduction via a movable nozzle piston in conjunction with a nozzle rod takes place and in addition air is sucked.
  • WO 94/20219 disclosed water jet regulator and flow limiter for sanitary fittings housed in a housing water jet splitting device, wherein a throttle plate takes a Vorordelung the amount of water and the fine adjustment is taken over by a throttle device in a cylinder hole plate and can be adjusted during operation.
  • a disadvantage of the known flow restrictors are a low mixing rate of fluid and gas and their complicated mechanical structure.
  • a flow rate limiter of the type mentioned in the present invention that connects to the inlet opening an inlet funnel.
  • the inlet funnel causes high flow rates of the fluid in the channel, in addition, the fluid is set in rotation. These high flow rates cause a negative pressure in the region of the outlet opening of the channel, so that high amounts of gas are sucked in via the gas channel and absorbed by the swirling fluid.
  • the flow rate of shower water for example, can thereby be reduced from usually 15 to 19 L / min to 3 to 5 L / min, without the showering comfort is reduced, because due to the air suction through the gas suction opening, the volume of the water jet is increased. This allows a significant cost reduction in water consumption and energy costs for hot water treatment.
  • This waveform corresponds to phenomena known in nature in which forces can act optimally (for example: tornadoes, Coriolis force, etc.).
  • Increased gas absorption and thus volume increase of the fluid is achieved when the at least one channel for the fluid and the at least one gas outlet opening in a plane, for example, open into a mixing chamber.
  • this has at least one recess for receiving magnetic, mineral or organic material on. According to various studies, magnets influence the deposition of lime in water pipes and fittings.
  • the object is achieved in that arranged a flow restrictor between the inlet opening and outlet opening of a recording.
  • This mount can be mounted in a few easy steps to hoses, pipes, fittings and other elements intended for the transport of fluids.
  • the gas suction port of the flow restrictor is in the mounted state with a gas intake passage of the receptacle in alignment, so that an unhindered gas suction is ensured.
  • the at least one channel for the fluid and the at least one gas outlet opening open into a mixing chamber which is permeable in the direction of flow.
  • the mixing chamber has a frustoconical cross-section, maximum gas absorption of the fluid takes place.
  • the flow restrictor used in the receptacle may vibrate due to the high flow rate of the fluid. This leads to unwanted noise (whistling, roaring, etc.).
  • the flow rate limiter has at least one groove on the outer jacket surface.
  • a receptacle can be realized, in which the receptacle on the inner circumferential surface has at least one groove.
  • the outer surface of the recording made smooth.
  • At least one means for regulating the flow rate is provided in the receptacle.
  • This agent can be additionally actuated from the outside, for example by an Allen key.
  • the housing has at least one recess for receiving magnetic, mineral or organic material in the region of the outlet opening or in the region of the flow rate limiter.
  • the material placed in the recess may be, for example, mineral material used for therapeutic purposes. For example, semi-precious stones are used to energize drinking water.
  • the receptacle can be used in a method for mixing at least one fluid with at least one gas, wherein the flow rate of the at least one fluid is reduced and its flow rate is increased, and the fluid is fluidized and then mixed with the at least one gas.
  • the turbulence of the fluid allows a maximum absorption of gas volume.
  • This method when water is used as a fluid and air as a gas, is suitable for increasing the oxygen content of the water, which may have been stored for a long time in, for example, pipes or tanks under pressure, and thus upgrading it as drinking water.
  • the intake AUF shown in Figure 1 for flow rate limitation is used for example in showers to reduce water consumption.
  • the heart of the recording AUF is the flow rate limiter DUR shown in FIG. It has an inlet opening IN in a flow body DUK, which has an inlet funnel ELT through which the fluid, in this case water, can enter the channel KAN.
  • the flow rate limiter DUR shown in FIG. 2 can be used without the receptacle UP shown in FIG. 3.
  • one piece of hose per hose piece can be attached to each of the two longitudinal ends of the flow rate limiter DUR associated with the inlet opening A and the outlet opening DUR.
  • the receptacle UP as shown in Fig. 3, consists of a housing GEH, each having a thread in the region of the inlet port INL and the outlet port OUT (not shown in the figures), for example, for mounting the receptacle UP in a shower hose serve.
  • the surface OBE of the housing GEH is made smooth, this allows easy cleaning of the receptacle AUF, a property that is also desirable in terms of sterility, in hospitals, for example.
  • the housing GEH has a gas intake duct GAS, which, with the flow restrictor DUR inserted, is in alignment with its gas intake opening GAF (FIG. 1).
  • the gas channel GKA is secured with a check valve RUC, thus, in the case of pressure fluctuations or the like, no water can escape at the gas suction opening GAF.
  • the outlet opening OUT of the flow restrictor DUR is in a plane with the outlet opening GUF of the gas channel GKA and opens into a mixing chamber MIS.
  • This mixing chamber MIS has a frusto-conical cross section, which ensures optimum mixing of the water with the air.
  • the flow restrictor DUR is used in this embodiment of the invention without additional fastening means in the housing GEH recording UP.
  • This has the advantage that the flow restrictor DUR can be removed in a few steps from the receptacle OP, for example, for cleaning purposes, or it can be used as a substitute equipped with, for example, different channel diameter flow rate limiter.
  • a recording AUF can be equipped with different flow rate limiters.
  • the flow restrictor DUR in the embodiment described here in the receptacle ON only used and not additionally fixed it may come to vibrate the flow restrictor DUR in the recording OPEN due to the high passage speeds of the water. This vibration is associated with undesirable noise.
  • the outer jacket AMA of the flow body DUK has a slot NUT.
  • means MIT are shown, which regulate the inflow or outflow of the water.
  • a pin which has an enlarged tip (not shown) is brought into the channel KAN or into the outlet opening OUT. This reduces the diameter of the channel or the outlet opening OUT, and the flow is reduced.
  • the positioning of the pen tip can be done for example by turning the pin in a corresponding thread.
  • the media used are water as fluid and air as sucked gas.
  • any fluids liquid or gaseous is conceivable.
  • the further embodiment of the invention shown in FIG. 5 has a recess AUN in the region of the outlet opening OUT. This is, as shown in Fig. 6a, annular.
  • the recess AUN serves to accommodate magnetic material. Investigations have shown that magnetic fields have a positive influence on limescale deposits in pipes and fittings carrying water. The use of magnets can therefore reduce possible calcification in the flow restrictor DUR or in the receptacle OP.
  • FIGS. 6b to 6d show further embodiments of the recess AUN.
  • the recess AUN can also be designed in the form of two or more bores, which are arranged symmetrically around the outlet opening OUT.
  • the position of the recesses AUN can be realized in the housing GEH or also in the flow rate limiter DUR.
  • Fig. 7 are located in the housing two recesses AUN, which are arranged in the region of the flow rate limiter DUR, while in the variants shown in FIGS. 8 and 9, the recesses AUN are formed in manufacturized DUR.
  • the latter embodiment has the advantage that it is easy to manufacture.
  • the recesses can be arranged in various ways in the device. Likewise, combinations of the embodiments described above can be realized. Likewise, the recess may be formed so that the inclusion of a plurality of magnets next to each other or inserted into each other is possible.
  • the use of the recesses is not limited to the inclusion of magnetic material.
  • the inclusion of mineral or organic material such as semi-precious stones, Schuessler salts or Bach flower essences may be provided for therapeutic purposes. Combinations of the different materials are also possible.
