Definitions
- the invention relates to a flow limiter with a flow body, the flow body being penetrated by at least one channel through which a fluid can flow, with an inlet opening and an outlet opening, and at least one gas channel with a gas suction opening and a gas outlet opening for a fluid to be mixed with the fluid emerging from the channel Gas is provided.
- the invention relates to a receptacle for limiting the flow rate with an inlet opening and an outlet opening for at least one fluid, the inlet opening having a larger cross section than the outlet opening.
- the invention also relates to a method for mixing at least one fluid with at least one gas, including water and air.
- a recording of the type mentioned is known for example from DE 3604 267 AI. It relates to a holder for limiting the flow rate, the flow being reduced by means of a movable nozzle piston in connection with a nozzle rod, and air is additionally drawn in.
- the water jet regulator and flow limiter for sanitary fittings disclosed in WO 94/20219 contains a water jet dividing device accommodated in a housing, a throttle plate taking on a throttling of the amount of water and the fine adjustment being carried out by a throttle device in a perforated cylinder plate and being adjustable during operation is.
- a disadvantage of the known recordings is a low mixing rate of fluid and gas and their complicated mechanical structure.
- a flow limiter of the type mentioned at the outset in that an inlet funnel connects to the inlet opening.
- the inlet funnel causes high flow rates of the fluid in the channel, and the fluid is also set in rotation. These high flow rates create a negative pressure in the area of the outlet opening of the channel, so that high gas quantities 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 reducing shower comfort, because the volume of the water jet is increased due to the air intake via the gas intake opening. This allows a significant reduction in water consumption and energy costs for hot water preparation.
- This curve shape corresponds to phenomena known in nature where forces can work optimally (e.g. tornadoes, Coriolis force, etc.).
- the production of a flow rate limiter according to the invention is made considerably easier if the at least one channel is of circular cylindrical design and is arranged axially in the flow body.
- the suction of the gas can be interrupted due to pressure differences in the supply of the fluid and the fluid can get into the gas channel. This effect can be prevented if a check valve is advantageously arranged in the gas channel.
- this has at least one recess for receiving magnetic, mineral or organic material. According to various studies, magnets influence the deposit of lime in water-carrying pipes and fittings.
- a flow rate limiter is arranged between the inlet opening and outlet opening of a receptacle.
- This holder can be easily attached to hoses, pipes, fittings and other elements that are intended for the transport of fluids.
- the gas intake opening of the flow limiter is in alignment with a gas intake duct of the intake in the assembled state, so that an unobstructed gas intake 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 flow direction. This has the advantage that the mixing of the fluid with the gas takes place after the acceleration of the fluid in the channel.
- the mixing chamber has a frustoconical cross-section, the maximum absorption of gas by the fluid takes place.
- the flow rate limiter inserted in the receptacle can vibrate due to the high flow rate of the fluid. This leads to undesirable noise (whistling, roaring, etc.).
- the flow rate limiter has at least one groove on the outer lateral surface.
- Such a receptacle can also be implemented, in which the receptacle has at least one groove on the inner lateral surface.
- the outer surface of the receptacle is smooth in a further preferred embodiment of the receptacle.
- At least one means for regulating the flow rate is provided in the receptacle.
- This means can also be operated from the outside, for example, using 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 can be, for example, mineral material that is used for therapeutic purposes.
- semi-precious stones are preferably used to energize drinking water.
- the use of the flow limiter for mixing water as a fluid and air as a gas is one of the preferred applications of the invention, but the invention can also be used for swirling and mixing a wide variety of liquids or gases with an aspirated gas.
- the receptacle can be used in a method for mixing at least one fluid with at least one gas, the flow rate of the at least one fluid being reduced and its flow rate being increased, and the fluid being swirled and then mixed with the at least one gas.
- a maximum absorption of gas volume is made possible by the swirling of the fluid.
- This method water is used as the fluid and air as the gas, is suitable to increase the oxygen content of the water, which may have been stored under pressure for a long time in pipes or tanks, for example, and thus to upgrade it as drinking water.
- Fig. 1 is a receptacle for a flow limiter according to Fig. 3 with built-in. 2 in longitudinal section,
- FIG. 3 shows a receptacle for a flow rate limiter without a flow rate limiter inserted in longitudinal section
- FIG. 4 shows a receptacle for a flow rate limiter with a built-in flow rate limiter according to FIG. 3 and additional means for reducing the cross section in the channel or outlet opening,
- FIG. 5 shows a receptacle for a flow rate limiter according to FIG. 3 with a built-in flow rate limiter according to FIG. 2 with recesses in the area of the outlet opening in longitudinal section
- FIG. 6a-d view of Fig. 5 along the line A-A
- Fig. 7-9 further versions of a recording according to the invention
- the receptacle AUF shown in FIG. 1 for limiting the flow rate is used, for example, in showers to reduce water consumption.
- the centerpiece of the UP opening is the flow rate limiter DUR shown in FIG. 2. It has an inlet opening EIN in a flow body DUK, which has an inlet funnel ELT through which the fluid, in this case water, can enter the channel KAN.
- This special shape causes the water to rotate as it passes through the KAN canal and accelerates it in the KAN canal.
- Due to the high passage speed of the water a vacuum is created in the space below the outlet opening AUS, which causes gas intake, for example air, in the gas duct GKA.
- the sucked-in air mixes with the accelerated, swirling water.
- the flow rate limiter DUR shown in FIG. 2 can be used without the receptacle AUF shown in FIG. 3.
- a piece of hose can be attached to the two longitudinal ends of the flow rate limiter DUR assigned to the inlet opening IN and the outlet opening OUT by means of hose binders.
- the receptacle OPEN as shown in FIG. 3, consists of a housing GEH, each of which has a thread in the area of the inlet opening INL and the outlet opening OUT (not shown in the figures), which are used, for example, for mounting the receptacle OPEN in a shower hose ,
- the surface OBE of the housing GEH is smooth, this allows easy cleaning of the receptacle OPEN, a property that is also desirable with regard to sterility, for example in hospitals.
- the housing GEH has a gas intake duct GAS which, when the flow rate limiter DUR is used, is in alignment with its gas intake opening GAF (FIG. 1).
- the gas duct GKA is secured with a non-return valve RUC, so that no water can escape from the gas intake opening GAF in the event of pressure fluctuations or the like.
- the outlet opening AUS of the flow rate limiter DUR is located on one level with the outlet opening GUF of the gas duct GKA and opens into a mixing chamber.
- This mixing chamber MIS has a frustoconical cross-section, which ensures an optimal mixing of the water with the air.
- the flow rate limiter DUR is inserted into the housing GEH of the receptacle OPEN without additional fastening means.
- an UP adapter can be equipped with different flow rate limiters.
- the flow rate limiter DUR in the embodiment described here is only inserted into the receptacle OPEN and is not additionally fixed, the flow rate limiter DUR may vibrate in the receptacle 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 groove NUT.
- the groove is on the inside of the jacket IMA of the receptacle OPEN.
- agents MIT are shown that regulate the inflow and outflow of the water.
- a pin which has an enlarged tip is placed in the channel KAN or in the outlet opening OUT. This reduces the diameter of the channel or outlet opening OUT and the flow is reduced.
- the pen tip can be positioned, for example, by rotating the pen in a corresponding thread.
- the media used are water as the fluid and air as the 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 area of the outlet opening OUT. As shown in FIG. 6a, this is ring-shaped.
- the recess AUN is used to hold magnetic material. Studies 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 limescale deposits in the flow rate limiter DUR or in the intake AUF.
- 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 there are two recesses AUN in the housing which are arranged in the area of the flow rate limiter DUR, while in the variants shown in FIGS. 8 and 9 the recesses AUN are formed in the flow rate limiter DUR.
- the latter version has the advantage that it is easy to manufacture.
- the recesses can be arranged in the device in a wide variety of ways. Combinations of the above-described embodiments can also be implemented. Likewise, the recess can be designed in such a way that it is possible to accommodate a plurality of magnets placed side by side or one inside the other.
- the use of the recesses is also not limited to the reception of magnetic material.
