Definitions
- the present invention relates to a mixing valve according to the preamble of the independent claims
- Mixing valves and in particular three-way mixing valves are used in heating systems to control the heating flow with the boiler flow or the heating return to connect e.g. by adding water to the
- a circulating pump that usually moves the heating medium through the system is then usually arranged.
- FIG. 1 shows the fitting according to the invention in a position in which the heating return is connected to the heating flow
- FIG. 2 shows the fitting according to the invention in a position in which the
- Boiler flow is connected to the heating flow
- 3 shows the valve according to the invention according to FIG. 1 in an intermediate position, in which the boiler flow and the heating return are connected to the heating flow 4, in which the boiler flow is connected to the heating flow
- FIG. 6 the fitting according to the invention according to FIG. 4, in which the boiler flow and heating return are connected to the heating flow
- a mixing valve housing 10 has an inlet connection 12 for the boiler flow, an outlet connection 14 for the heating flow and an inlet connection for the heating return not visible in this illustration.
- the inlet connection 12 is connected to a lower chamber 16, the heating flow is connected to a middle chamber 18 connected and the heating return is connected to an upper chamber 20 All chambers 16, 18 and 20 are connected to one another via aligned holes A hollow and axially displaceable shaft 22 passes through these holes and carries a pump wheel 24 in the area of the middle chamber 18.
- the upper chamber 20 is formed on a housing cover 26 which, when removed, permits the use of the pump wheel 24 with the hollow shaft 22 in the middle chamber 18. In the position shown in FIG.
- the hollow shaft 22 lies with its open lower end at the bottom of the lower chamber 16 and thus blocks access to the Boiler flow into the pump wheel 24 and the middle chamber 18, on the other hand, perforations 28 in the hollow shaft 22 in the region of the upper chamber 20 establish a connection between the heating return flow and the pump wheel 24 or the middle chamber 18
- the hollow shaft 22 protrudes upward out of the upper chamber 20 and is connected to the rotor 30 of a motor, the stator winding 32 of which is arranged in a pot-shaped housing 34 which is flanged onto the housing cover 26
- Stator winding 32 is axially divided into two windings 32 'and 32 "in order to achieve different positions of the rotor 30 and thus of the hollow shaft 22 by separate or simultaneous excitation of the windings 32', 32".
- the lower winding 32 is energized to drive the impeller 24 via the rotor 30 and the hollow shaft 22, but the excitation is sufficient to achieve the required pump performance
- An insert 36 mounted concentrically on the inside of the pot-shaped housing 34 in the cover area serves to guide the hollow shaft 22.
- Fig. 2 shows a position of the mixing valve with an integrated circulation pump, in which the boiler flow is connected to the heating flow and the admixture of the heating return is separated the lower end of the hollow shaft 22 enables unimpeded access of the boiler flow to the pump wheel 24 and the perforations 28 are at a height where no connection is made with the heating return
- Fig. 3 shows the position of the mixing valve with integrated pump, in which both the boiler flow and the heating return are connected to the heating flow. This position is achieved by energizing both stator windings 32 'and 32 ", whereby the rotor 30 assumes a central position, so that lower end of the hollow shaft 22 allows partial access to the boiler flow and the perforations 28 are at a height at which a connection to the heating return is made at least partially
- the stator 132 of the motor comprises three stator windings 132, 132 ′′ and 132 ′ ′′ arranged one above the other, the rotor 30 being able to assume different positions through separate or joint excitation of the stator windings 3, as is also the case in the exemplary embodiment according to FIGS. 1 to 3 was the case
- the rotor 30 is connected via a sleeve-shaped intermediate element 50, which is not made of iron, to a motor shaft 122 by means of a nut 52.
- the motor shaft 122 is mounted in a lower housing attachment 54 and an impeller 124 is attached to the motor shaft 122 and with it as a pump wheel rotatable together
- the impeller 124 sits in a receiving housing 56, which works as a displaceable control body and consists of two symmetrical parts, between which the impeller 124 is located.
- the receiving housing 56 has two cylindrical lugs 58, 58 ', which are provided with bushings 60, 60' are provided which can be predetermined, for example, by axially parallel bores distributed over the circumference.
- the lugs 58, 58 ' can also be predetermined by two concentric sleeves which are connected to one another via radial webs KV, the heating flow HV and the heating return HR forth, the impeller 124 causes the transport of the medium
- the vanes of the impeller 124 extend radially over an area that lies outside the medium flowing through the passages 60, 60 '.
- Two shield plates 62, 62' which extend radially outward from the cylindrical projections 58, 58 'enclose the impeller 124 between them the shielding plates 62, 62 'can be locked over the circumference at various points at a distance from one another.
- the shielding plates 62, 62' have here not recognizable, aligned U-shaped recesses in the edge, which one into the Grip over the inserted pin 64 housing 10 so that they are axially movable but held in the direction of rotation circlips 66, 66 'secure the receiving housing 56 on the motor shaft 122, so that it is axially movable with the motor shaft 122 when the stator windings 132', 132 " and 132 '”are excited accordingly to move the rotor 30 and thus the control body
