Definitions

  • the present invention relates to a fluid circulation and distribution apparatus, and in particular a three-way pump.
  • Three-way pumps are known in which the opening and / or closing of the channels depends on the operating conditions of the pump.
  • pumps which have an inlet and two outlets, each of which is supplied as a function of the direction of rotation of the turbine.
  • Swiss Patent No. 499018 proposed a three-way pump with a single outlet and two inlets.
  • a diaphragm or membrane system is used defining two sealed chambers, one of which is in relation to the pump outlet and therefore at high pressure, and the other of which is in relation to the inlet of the volute and therefore at low pressure.
  • the difference in pressures which results therefrom on either side of the diaphragm ensures, together with a calibrated spring, the closing and / or opening of the liquid inlet orifices.
  • This system has the double disadvantage of requiring an absolute seal between the two chambers. on the other side of the membrane, and a meticulous tare adjustment mechanism, which must also be adjustable from the outside, since there is no direct access.
  • the object of the present invention is to remedy these drawbacks by proposing a fluid circulation device with at least two inlets and one outlet, of simple construction, usable both in open circuit and in closed circuit and allowing closing and / or l 'selective opening of each of the entrances under very simple conditions.
  • It relates to a fluid circulation device with two inlets and an outlet, with a partition defining a suction chamber in which the two inlets are located as well as their closing devices, and a discharge chamber constituting a volute in which turns a turbine with two directions of rotation, characterized in that it comprises, in the discharge chamber, mobile means capable of ensuring, as a function of the flow of fluid, the control of the closing devices of the two inlets.
  • the movable means arranged in the delivery chamber are constituted by a pallet which can oscillate around an axis diametrically opposite to said pallet relative to the axis of the turbine and parallel to it , the closing devices of the two inlets being integral with said pallet and oscillating around the same axis.
  • the lever arm thus obtained increases the pressure ensuring the closure of one or the other of the inlets.
  • the device comprises a symmetrical volute, the movable pallet reconstituting, in its extreme positions, an asymmetrical geometry of the volute, so as to promote the flow of the fluid in the direction of turbine rotation.
  • the invention also provides for improving the efficiency of the turbine by equipping it with radial blades of various lengths, the alternation of such blades of different lengths ensuring better flow of the liquid through the turbine.
  • the pump illustrated in FIGS. 1 to 5 consists of a motor 1 and a pump body 2.
  • a partition 3 divides this pump body into two parts: a suction chamber 6 and a discharge chamber 4. This constitutes a volute in which a turbine 5 rotates and the two chambers are connected by a passage 7 through which passes the suction nozzle 8 of the turbine 5.
  • discharge chamber 4 does not have the asymmetrical profile which participates, in normal volutes, in the movement towards the outlet of the current of centrifugal fluid created by the rotation of the turbine.
  • a part 10 in the form of a circular crown, as it appears in FIG. 4, carries, on the one hand, a pallet 11 which is placed immediately upstream of the outlet 9 of the delivery chamber, and on the other hand, a axis 12, diametrically opposite to the pallet 11 relative to the axis of the turbine 5, and passing through the partition 3 to open into the suction chamber 6.
  • the end of the axis 12 carries an arm 13 to which it is secured by a screw 25 and this arm carries, in turn, a valve body 14 with two faces 15 and 16.
  • the suction chamber 6 has three orifices: an orifice 17, closed by a plug 18, which allows access to said suction chamber, and two other orifices located face to face and arranged on the same axis.
  • One of these orifices carries a nozzle 21, one end of which 19 constitutes an inlet to the pump and the other end of which opens into a pipe (not shown) connected to a source of water.
  • the other orifice carries a nozzle 22, one end of which constitutes the second inlet of the pump and the other end of which opens into a pipe (not shown) connected to another source of water.
  • the motor 1 has a control, not shown, with two operating positions, one ensuring the rotation of the turbine in the direction of the arrow in solid line 23 in FIG. 4, and the other in the direction of the arrow in dotted lines 24 of the same figure.
  • the turbine illustrated in FIG. 6 is different from that appearing in FIG. 4 in particular in that it is equipped with blades of different lengths.
  • a blade 43 has been placed, the length of which is substantially half of a large blade and, halfway between the large blades 42 and the half-length blades 43, the blades 44 are available, the length of which is substantially half of the half-length blades 43.
  • the pallet 11 modifies the internal geometry of the delivery chamber and thus participates in guiding towards the outlet of the centrifugal current created by the turbine.
  • the centrifugal current then created in the discharge chamber 4 is established in the same direction and exerts, on the pallet 11, a pressure which will cause the angular displacement of the circular part 10 until said pallet 11 comes position on the other side of the outlet 9, in a position symmetrical to that illustrated in Figure 3.
  • the vane 11 has several different functions: it detects the direction of rotation of the turbine via the liquid ring created, it transmits the information to the valve body 14 via the circular part 10 and the axis 12, and it participates in the good flow of the liquid ring towards the outlet 9.
  • the pump illustrated in FIGS. 7 and 8 comprises a closed body 26, the separation between the suction chamber 27 and the discharge chamber 28 being obtained by a removable partition 29 comprising a central orifice 30 which connects the two chambers and in which is located locates the suction nozzle of the turbine not shown.
  • a pallet 31 is carried by a circular arm 32 having an axis 33 journalled in a boss 34 of the removable partition 29.
  • An arm 35 carrying a valve 36 with two faces 37 and 38 is integral with the axis 33.
  • the valve 36 made of elastic material, is articulated on a ball joint 39 at the end of the arm 35 by virtue of a housing 45 giving it sufficient angular freedom relative to the arm 35 to close one or the other of the two end pieces. 40 and 41 constituting the two inputs of the pump.
  • a first advantage of the embodiments described is that the entire multi-way valve function does not require any system for sealing the fluid with respect to the outside, no moving part being in contact with the latter.
  • a second advantage is the significant improvement in the efficiency of the pump obtained by the transformation of a symmetrical delivery chamber into an asymmetrical chamber ensuring the good flow of the centrifugal fluid current, whatever the direction of rotation of the turbine.
  • a third advantage is the fact of ensuring, at will, either the sealing between two circuits, or on the contrary their automatic junction under certain conditions. For this, it suffices to play on the dimensions, the shape or the like of the pallet, or on the sections of the entries so as to vary the opposing pressure to the closing pressure.
  • valves 11 or 31 It would be possible, for example, to control the valves by an electromagnetic system which would ensure their placement in order to close one or the other of the inputs as a function of information transmitted by the pallets 11 or 31.
  • the described pump has two inlets placed face to face. It is obvious that it could count more and that would be otherwise arranged, for example, shifted as necessary.
  • the example described relates to an apparatus for circulation and distribution of a liquid
  • the invention also applies to apparatus for circulation and distribution of gaseous fluids.
