- the sensor 7 detects cold water, the water is diverted from the line 1 into the line 2 and thus flows back to the heating system.
- the flow process from the hot water pipe 1 via the valve 32 into the cold water pipe 2 is stopped and warm water can be removed at the removal point 12.
- FIG. 8 corresponds to the line content of the hot water pipe 1 substantially, preferably exactly the contents of the container 5, when it is filled only with warm water.
- the valve 9, which may be designed, for example, as an electric valve, is used only as described below to supplement the amount of cold water that may be necessary. Flows namely water from the sampling point 12 before the hot water column from the hot water reservoir W arrives at the sampling point 12, so this cold amount is missing to fill the cold water reservoir K and the hot water column shoots over, ie it flows at least partially into the line 2, which is undesirable.
- the valve 9 the shortage of hot water can be supplemented, ie the valve 9 is open only during the first supporting pumping operation. If no more warm water in the container 5, due to the design, no cold water flows from the cold water reservoir K from the container 5 in the hot water pipe and vice versa.
- FIG. 9 shows a further variant of the system according to the invention.
- no sensor for example a thermosensor, needs to be arranged in front of the valve 32, since the line content of the hot water line 1 to the valve 32 corresponds to the content of the hot water reservoir in the container 5.
- the pump 4 pumps the cold water from the cold water reservoir K of the container 5 via the cold water line 2 the other valve 32 in the hot water pipe and the warm water from the hot water pipe 1 is pumped into the hot water reservoir W of the container 5 until the container 5 is completely filled with warm water.
- this system is particularly suitable for a spatial proximity of the two removal points 12.
- the container 5 near the extraction point and a container 5 near the Have heating system combine with a pump so that through the faster inflow of warm water to the withdrawal point 12 the container 5 in near the sampling point can be significantly smaller than the container in the Near the heating system and that the volume of the container 5 near the Withdrawals so that it can be much smaller than the line content 1 of their Feeder.
- FIG. 12 shows a schematic representation of a first valve 32 according to the invention. Shown is a valve 32, which opens only at positive pressure from line 1, but not by a negative pressure in line 2.
- the valve 32 is particularly for an arrangement behind the last container 5 in the 3, 5, 6, 7, 9 , 10 and 11 illustrated embodiment, in which the cold water line is used as a return line suitable.
- the power of the circulation pump 4 and the execution and adjustment of the valve 32 by the adjusting screw 31 are preferably coordinated.
- the active surface 40 for the liquid from line section 1 on the closure plate 29 is comparatively large, that of the liquid from line section 2 comparatively small. Thus, even a relatively small relative overpressure in line section 1, the closure plate 29 lower against the force of the spring 30, which then allows the flow of liquid from line section 1 in line section 2.
- the skilled person understands that not necessarily springs are used, but that the necessary forces can be applied with suitable design of the valve as well by the weight forces generated by the masses of the individual components.
- the shape of the piston housing 38 shown here allows also a non-vertical installation of the valve 32, wherein in addition to a Membrane can be dispensed with.
- the piston housing 38 and the spring housing 33 are located in front of the Assembly preferably under atmospheric pressure filled with air before. In this case forms after entering the water in the valve 32 of the above-described Air / water level, which allows adjustment of the valve 32.
- FIG. 13 shows a schematic illustration of a second valve 37 according to the invention.
- the valve 37 opens already at a low relative negative pressure in line 1, but not at an overpressure on the opposite side of the valve 37. This overpressure, for example, by inflow from a hot water reservoir (not shown), as shown for example in Figure 5, respectively.
- the closure plate 29 has on the line section 1 side facing a large effective area 40 for the water, whereas the active surface on the side facing away from the line 1 a relatively small attack surface for the water. If the piston cover 29 is raised, the water in line 1 can flow in, since the spring housing 33 and the piston housing 38 are not sealed against each other. There is thus an adjustment of the valve 37 by the influence of the air / water level 35 instead.
- the air trapped in the valve 37 also ensures by its compressibility that the piston cover 29 can detach from the seals 28.
- the pressure, which occurs during the flow of water within the piston housing 38 and the spring housing 33, is preferably slightly below the static pressure and above the release vacuum in line 1 to open the valve 37.
- the spring 34 in this case still provides up to one with the adjustment screw 31 adjustable limit value of the negative pressure for the concern of the closure plate 29 to the seals 28.
- the shape of the piston housing 38 shown here also allows a non-vertical installation of the valve 32, which also can be dispensed with a membrane.
- the adjustment of the valve 37 by running the water into the piston housing 38 and / or the spring housing 33 is preferably carried out only after assembly after the valve 37 has reached its final position.
- the piston housing 38 and the spring housing 33 are preferably filled with air under atmospheric pressure prior to assembly. In this case forms after entering the water in the valve 37, the above-described air / water level, which allows adjustment of the valve 37.
- Figure 14 shows an embodiment of the valve according to Figure 12, wherein the spring housing and the valve housing are made in one piece.
- Figure 15 shows an embodiment of the valve according to Figure 13, wherein the spring housing and the valve housing are made in one piece.
- FIG. 16 shows a combination of the valves 32 and 37.
- the pressure in the valve relaxes. Even a slight overpressure in the hot water pipe 1 pushes the piston down because it has a large attack surface due to its depression.
- Cold water flows past the thermocouple / valve until incoming warm water closes the cold water outlet 46 and cold water inlet 47 opens. Due to the still existing pressure of the pump, the entire valve 45 is pressurized again. Since the thermocouple is down, the cold water inlet 47 is opened from the cold water line 2 via a valve 32 so that reflux of cold water from the line section 2 into the line section 1 is now possible. This displaces the warm water from the line section 1.
- a cooling rate at 7 in 45 which corresponds to the cooling rate of the warm water in the line 1, is advantageous.
- FIG. 17 shows a schematic illustration of a second valve 22 according to the invention.
- the clamping bolt 25 In the initial position of the clamping bolt 25 is provided with lever arm 23 in the middle position with balanced voltage of both valves 22.
- the right clamping bolt 25 Upon removal of water from the line 26, the right clamping bolt 25 is pushed up the right valve 22, whereby the left clamping pin 25 is pressed down on the valve 22 of line 27 via the lever arm 23.
- the clamping bolt 25 and the lever arm 23 remain first, even in the case of removal of water from line 27.
- the left valve 22 can be opened solely by the water pressure, however, the operation of the left valve 22 is due to the design of the valves 22 with lever arms 23 heavier than the right valve 22. After completion of each removal starts the circulation.
- the higher pressure in the line is measured, or it can be an acoustic or electrical, but preferably not audible signal can be used.
- the lever arm 23 controlled by the control and support member 24 to.
- the right valve 22 is now stretched more than the left valve 22, whereby the circulation of water from now on via line 27 takes place.
- the control / influence of the lever arm 23 ends by the control and support member 24.
- the current status of the system can preferably by three temperature sensors, which at Inlet, line 26 and arranged on line 27 are registered.
- the clamping bolt 25 and the lever arm 23 then go back to the starting position.
- an electrically controlled opening and closing of the valves 22 can also take place.
- FIG. 18 shows a schematic representation of the operating principle of a flow valve 10 according to the invention for a water pipe 1, 2.
- the flow valve has a lock plate mounted on a bearing 44, which is arranged above the connection point between line 2 and line 1 and reversibly closes line 1 with respect to line 2.
- the flow valve 10 serves to close the connection between line 1 and line 2 when a predefined mass flow in line 2 is exceeded. If there is a certain water pressure both in line 1 and in line 2, then the ratio of the two water pressures is decisive for whether the flow valve 10 closes the two lines against each other or connects the lines together.
- the water stored in line 1 presses from below against the flow valve and against the water pressure present in line 2.
- the water flowing in line 2 flows over a slope arranged inside the line 2 in front of the connection point and impinges on the inclined plane arranged on the flow valve 10. If the water also flows over the inclined plane, then the closure plate 29 of the flow valve 10 is additionally pressed onto the connection point between line 1 and line 2 and thus closes line 1 with respect to line 2.
- a circumferential seal arranged to seal the line 1 is at the edge of the connection point between line 1 and 2, a circumferential seal arranged.
