Definitions

  • the present invention relates to a holding valve according to the preamble of claim 1 and known from document FR-A-1 080 677.
  • This known valve has in particular the disadvantage of not allowing the level of water to be maintained in the downstream basin when the water demand downstream from this basin varies and when maintaining the water level in this downstream basin is more useful than maintaining the water level in the upstream basin.
  • the object of the invention is to provide an automatic level maintenance valve making it possible to easily switch from the adjustment of the upstream level to the adjustment of the downstream level and of adjusting the set value, all either manually or by remote control, by transmission of a low power signal by means, for example, of a telephone line.
  • Each of said boxes has a substantially constant horizontal section over its entire useful height and the center of gravity of the assembly fixed to the frame is placed substantially at the altitude of said axis of rotation so that the torque applied to the frame is controlled. only by the difference between the water levels in the regulating tank and in the basin at predetermined level.
  • the adjustment means comprise a source of compressed gas with a limited flow rate provided with a pipe whose open end is immersed in the upstream basin at an altitude controlled by said adjustment means, a switching valve for connecting this source to the upper opening of the regulating box, and a switchable member for connecting the low opening of the downstream box to the upstream basin or to the downstream basin depending on whether this box is regulating or not, the low opening of the upstream box opening into the upstream basin even when it is non-regulatory.
  • Said adjustment means comprise a water weir at an adjustable altitude, means for filling this weir with limited flow, and means for connecting the bottom opening of the regulator box to these filling means, the top opening of this box being open to the atmosphere.
  • the filling means of the spillway comprise a pipe opening into the upstream basin, this weir spilling into the downstream basin.
  • the means for filling the spillway comprise an auxiliary basin supplied with clean water.
  • the lower opening of the non-regulating box communicates with the tank, the level of which is not regulated by an equivalent circuit, as for pressure losses, to an area opening between 2 and 0.02% of that of the surface free of water in this box, the upper opening of this box leaving a practically free passage to the air between the inside of this box and the air, so as to achieve a temporary and partial control of the level of the basin non-regulator in particular during communications between upstream and downstream adjustment.
  • the reference 1 represents the level of an upstream basin and the reference 2 the level of a downstream basin constituting for example two successive reaches of an irrigation channel.
  • the automatic valve shown is intended to maintain a constant upstream or downstream level. It comprises an apron 3 movable around an axis of rotation 4. The apron is secured to the axis of rotation by means of a frame 5 and controls the section for passage of the water above a concrete threshold 27.
  • An upstream box 7A secured to the deck is partially immersed in the upstream basin and a downstream box 7B secured to the frame is partially immersed in the downstream basin.
  • the bottom wall 8A of the box 7A carries a "bottom" opening 9 allowing partial filling of the box.
  • Reference 10 designates a grid to avoid the introduction of waste into the box.
  • Partial filling of the downstream box 7B is obtained by a switching valve 15 which connects said box either to the upstream tank via the pipe 13, or to the downstream tank.
  • the two boxes are connected to a source of compressed air with limited flow 20 by pipes 22, 23A and 23B and by switching valves 28A and 28B which connect either the upstream box or the downstream box to the pipe 22, l 'other box then being connected to the atmosphere.
  • the valves 28A, 28B and 15 are controlled simultaneously.
  • the gas escapes bubble by bubble through a pipe 24, communicating with the pipe 22, and the end 25 of which is immersed in the upstream basin, at a distance d from the level 1 of this basin.
  • the box 7A which becomes the regulating box, in communication with the gas source; the other box 7B is passive and acts as a shock absorber, it is brought to atmospheric pressure and the switching valve 15 connects it to the downstream basin.
  • the box 7B which becomes a regulating box, in connection with the gas source and, via the member 15, in connection with the upstream tank.
  • the box 7A is vented and becomes a damping box.
  • the upstream and downstream walls of the boxes, as well as the deck, are parts of surfaces of revolution around the axis of rotation, so that the hydrostatic thrusts on the walls do not induce a torque. Only the lower walls 8A and 8B of the boxes apply to the mobile frame a thrust proportional to the difference between the heights of water inside and outside the box considered.
  • the frame of the valve is studied so that the center of gravity 12 of the movable assembly is, for an average position of the valve, on the upstream side with respect to the axis of rotation 4 and in the vicinity of the horizontal plane passing through the axis of rotation.
  • This flow limitation improves the stability of the functioning of the upstream basin-valve-downstream basin system in the case where these basins are channel reaches, and therefore the quality of the regulation. It is appropriate for this, in the case where this flow passes through a simple opening through a sheet, that the area of this opening has a suitable value relative to that of the free surface of the water in the box. This value depends on the nature of the diversion bays upstream and downstream of the irrigation canal. It is generally between the limits previously indicated. In the case where water flows through a circuit, it is necessary to consider the area of an opening which would be equivalent to this circuit with regard to pressure losses.
  • the constancy of the level position in the box chosen as the regulating box leads to the maintenance of the corresponding basin at a constant level: in fact by taking the example of adjusting the upstream level, if the level of the upstream basin tends to rise , the level 11A of the water in the box 7A remains fixed, the hydrostatic thrust on the box increases and the valve completely opens the passage between the deck and the threshold 27 resting on the bottom because, due to the position of the center of gravity of the valve, the mechanical torque applied to it by its weight and the hydrostatic thrust is substantially constant whatever the angular position.
  • the level can be adjusted in the chosen basin by simply moving the pipe 24 vertically. Lifting the pipe will increase the level setpoint; pressing it will decrease the value of this setpoint.
  • the vertical movement of the pipe 24 can be carried out manually, or remotely by means of a remote-controlled motor.
  • the pipe 24 can be held by a chain 50, fixed by a link or by another depending on the distance chosen, to a fixed hook (manual adjustment).
  • the pipe 24 may be fixed by a cable 42 wound on a winch 40 driven by a motor 41 remotely controlled and powered by an autonomous power source such as a solar PIIE ( remote control setting).
  • the gas pressure can be supplied by a compressed air cylinder which is changed from time to time, or by a compressor activated by an independent energy source, such as a solar cell, or by the pressure difference of l between upstream and downstream basins.
  • the switching valves 15, 28A, 28B can be controlled remotely, allowing the choice of the basin for which it is desired to keep the level constant.
  • the air flows controlled by these valves being very low, they are small and can be controlled by a very low power which will generally be less than 10W.
  • Figure 2 is an alternative embodiment of the device of Figure 1, having simplified piping and valves.
  • the taps 28A, 28B have been replaced by a single tap 80, which is operated at the same time as the switching tap 15.
  • a simultaneous rotation of a quarter turn of the taps 80 and 15 makes it possible to pass to the constant maintenance of the level of the upstream basin (case of the figure) to the constant maintenance of the level of the downstream basin.
  • FIG. 3 represents an alternative embodiment of an automatic valve, for keeping the upstream or downstream basin at a constant level.
  • the elements common to Figures 1 and 3 have been given the same reference numbers.
  • the boxes 7A and 7B have openings 29A and 29B at their upper part, but the bottoms 8A, 8B are closed.
  • the levels 11A, 11B in the caissons are kept constant this time thanks to a weir 30 fed from the upstream basin by a pipe 31, discharging into the downstream basin, and connected to the low orifices 32A and 32B of the boxes by pipes 33A and 33B.
  • a circulation of water therefore takes place between the upstream basin and the downstream basin via the pipe 31 and the weir 30.
  • a pressure drop diaphragm 35 is placed on the pipe 31, the level 11A is then substantially equal to the level 36 of the weir 30.
  • Switching valves 34A and 34B put either the upstream box or the downstream box in communication with the pipe 31 and the weir 30, the other box then being connected directly to the basin in which it is partially immersed.
  • level 1 in the corresponding basin will also be constant.
  • the level of the basin is adjusted by vertically moving the weir 30, for example as indicated above for the displacement of the pipe 24 of FIG. 1.
  • valves 34A, 34B can be controlled remotely for the choice of the basin for which the level is to be kept constant.
  • FIG. 4 represents a valve according to the invention, for maintaining a constant level in a basin, which differs from that shown in FIG. 3 in that the boxes are no longer supplied by the upstream basin, but by a pipe 53 from an external basin shown diagrammatically at 52. The rest of the device is unchanged; there is shown the remote control of the setpoint, by winch and motor.
  • the advantage of this variant is that it can partially supply the system with water different from that of the upstream basin, this different water being able to be cleaner, which avoids or reduces the risks of clogging of pipes or valves with solid materials.
