Definitions

  • the present invention relates to the field of devices for introducing air into a tank or hydropneumatic network equipping a hydraulic pipe, in particular, in a sewage or chemical liquids disposal network.
  • a hydropneumatic tank can be used as a surge tank of a pipeline or hydraulic network to compensate for the effects of depression and overpressure caused for example by a pump stop or closing a valve.
  • the operation of such a reservoir is known in particular from the document FR 2 416 417 .
  • the water or the pressurized liquid located in the lower part is surmounted by air or gas also under pressure and whose quantity must remain substantially constant for the correct operation of the apparatus is ensured. Indeed, if there is lack of air, the protection of the pipe is insufficient and, if there is too much air, there is risk of air escape in this pipe, what it must be avoided.
  • the document EP 0 617 227 discloses an air regulating system for hydropneumatic tank comprising an air introduction chamber which can be emptied by an evacuation solenoid valve. An air inlet solenoid valve in the chamber is open. Then we close the first two solenoid valves and opens a filling solenoid valve to drive air to the tank.
  • the solenoid valves are controlled by a control means connected to a detector which emits a signal in case of level higher water level at the detector.
  • This system requires a power supply, which can be expensive in remote areas of the power grid and causes the loss of a certain amount of liquid, which is not desirable in case of drinking water and should be avoided obviously in the case of other liquids.
  • the document EP 0 895 020 discloses an air introduction device for a hydropneumatic reservoir into which the air is introduced into a low pressure zone, such as upstream of a pump, by the opening of a solenoid valve.
  • a low pressure zone such as upstream of a pump
  • a solenoid valve a low pressure zone
  • the liquid losses are suppressed but a power supply is necessary and the control of the introduction of air is done by liquid level sensors in contact with the latter so that the operation can be disturbed by deposits in case of pumping charged water.
  • the present invention aims to overcome these disadvantages.
  • the present invention aims to improve the introduction of air into a hydropneumatic reservoir.
  • the present invention aims to introduce a suitable amount of air when the need arises.
  • the device for introducing air into a hydropneumatic reservoir then comprises a sensor of the pressure in the hydropneumatic reservoir, a valve controlled by a signal coming from the sensor and opening in the open air on one side, a tube connected by a end to the valve and the end opposite to a pipe connected to the tank.
  • a first valve is disposed in the tube to prevent the passage of liquid in the tube to the valve and a second valve is disposed in the pipe between the reservoir and the tube. The second valve is closed when a pump mounted on the line is stopped and opened when the pump starts and runs. In this way, a mechanical air intake is triggered when the air pressure in the tank becomes too low. The presence of a power supply is no longer necessary.
  • the pipe may be a large diameter pipe, for example between 100 and 2500 mm, the hydropneumatic reservoir provides the anti-ram protection.
  • the tube may have a small diameter, of the order of a few tens of millimeters, for example from 5 to 40 mm.
  • the pipe opens into the tank at an altitude greater than that at which the tube opens into the pipe. This promotes the migration of the air introduced by the tube into the pipe to the tank.
  • the device comprises an air trap.
  • the air trap directs the air introduced into the pipe to the tank.
  • the senor comprises adjusting masses. It is thus possible, during commissioning, to make a fine adjustment adapted to the actual characteristics of the liquid network which always differ somewhat from the nominal characteristics.
  • the senor comprises at least one elastic adjustment element, for example, a spring.
  • the senor comprises a piston and a cylinder, one being fixed and the other mobile.
  • a control part of the valve can be connected to the moving part.
  • the connection can be provided directly, by means of a lever, for example an articulated lever arm.
  • the senor is connected to the valve by a lever arm.
  • the lever arm can be graduated. Adjustment masses can be arranged on the arm. It is thus possible to adjust in a manner similar to the use of a Roman scale.
  • valve is electrically operable.
  • the device comprises an electrical connection with the sensor.
  • the device may include an adjustment of the opening time of the valve.
  • the adjustment can be made on the pressure sensor or connected to the pressure sensor.
  • the device comprises a timed control member between the opening and closing of the valve.
  • the senor comprises a bellows disposed between a solid plate and a perforated plate.
  • the perforated plate can open into the tank.
  • a chamber can be defined between the bellows, the solid plate and the perforated plate.
  • the solid plate may be disposed in the upper position and the perforated plate in the lower position, the valve being in the form of a shutter disposed on an upper surface of the solid plate.
  • the closure may come into contact with an orifice of the tube.
  • the shutter seals the end of the tube.
  • this pressure becomes lower than a chosen pressure threshold, which can be modified by adjustment, the solid plate collapses, dragging with it the shutter, which then releases the orifice of the tube through which the air can circulate.
  • the first valve disposed on the tube remains closed. If the pressure in the pipe decreases, then the valve opens, the air from the atmosphere flows through the tube through the valve. A certain volume of air then enters the pipeline. Then when the pressure in the pipe increases again, for example when starting a pump, the first valve closes. The air is driven by the liquid in the pipeline to the tank and is introduced into the hydropneumatic reservoir, and is then compressed to the pressure prevailing in the gaseous part of the hydropneumatic reservoir, that is to say, the upper part.
  • the valve remains closed, regardless of the position of the first valve.
  • the second valve maintains a service pressure on the side of the hydropneumatic reservoir. The second valve closes during a pump stop and opens during a pump start or more generally when a recovery of the liquid flow in the pipe. Air introduced into the pipe upstream of the second valve then passes through the second valve and is moved by the movement of the liquid to the hydropneumatic reservoir.
  • the reservoir comprises an inner tube extending downwardly from an end of the reservoir.
  • the sensor is disposed in the tube.
  • the invention also relates to a hydropneumatic air refueling system comprising a hydropneumatic reservoir, a pipe connected to the reservoir and an air introduction device as described above.
  • the system may include a liquid circulation pump in the pipeline.
  • the second valve is closed when the pump is stopped and opened as soon as it starts and as long as it is running.
  • the pipe from the pump to the tank, is constantly rising.
  • the method for introducing air into a hydropneumatic reservoir connected to a pipe provided with a pump comprises steps for detecting the pressure in the tank by a sensor, opening a valve controlled by the sensor in the event of insufficient pressure in the tank, the pump being stopped, a valve of the pipe being closed; the valve being open, the atmospheric pressure begins in the tube causing the draining of the pipe; when the pump restarts, a valve disposed in the tube closes under pressure and prevents the rise of liquid in the tube, the air introduced into the pipe being discharged into the tank, the valve of the pipe opening.
  • the air introduction device is intended for a hydropneumatic tank 1 in the form of a balloon, a lower part 1b of which is connected to a hydraulic pipe 2.
  • the lower part 1b of the hydropneumatic tank 1 is generally filled with liquid, in particular water and an upper part 1a of the hydropneumatic reservoir 1 is generally filled with gas, especially air.
  • the amount of gas present in the upper part 1a of the hydropneumatic reservoir 1, must be between a lower limit and an upper limit depending on the dimensions of the hydropneumatic reservoir 1, the pipe and the expected operating pressures.
  • the hydropneumatic tank 1 does not adequately ensure the protection of the hydraulic system against water hammer.
  • the emptying of the hydropneumatic tank 1 may not be effected imperfectly, which prevents it from fulfilling its function. If an excessive quantity of gas is present, when the hydropneumatic tank 1 is emptied, gas may be sent to the pipe.
  • an air introduction device is installed upstream of the tank 1 in the pipe 2 and downstream of a feed pump 4 immersed in a water reservoir which may be a well, a borehole or a tarpaulin .
  • a check valve 5 is associated with the feed pump.
  • the valve 5 is installed on the pipe 2 between the pump 4 and the tank 1.
  • the valve 5 prevents a return of water from the tank 1 to the pump.
  • the air introduction device 3 comprises a pressure sensor 6 mounted on the tank 1 for detecting the pressure inside said tank 1.
  • the pressure sensor 6 is mounted on the upper part 1a of the tank 1, preferably at the top.
  • the pressure sensor 6 may be in the form of a pressure switch.
  • the pressure sensor 6 can be connected to the upper part 1a of the tank 1 by a pipe portion 7 in order to dispose the pressure sensor 6 above the tank 1, thus limiting the risk of liquid rising in the sensor of pressure 6.
  • the air introduction device 3 comprises a tube 8 of small diameter relative to the diameter of the hydraulic pipe 2.
  • the tube 8 is connected at one end to the hydraulic pipe 2 upstream of the valve 5, for example at a small distance of said valve 5.
  • the opposite end of the tube 8 is connected to a valve 9 for communicating the tube 8 with the outside atmosphere.
  • the valve 9 may be of mechanical or electromechanical type.
  • the valve 9 is controlled by a signal from the pressure sensor 6 via a control member 10 of the mechanical type. In other words, the pressure sensor 6 generates a mechanical signal transmitted by the mechanical control member 10 to the valve 9 controlled mechanically.
  • the air introduction device 3 also comprises a valve 11 disposed in the tube 8, for example near the junction between the tube 8 and the hydraulic pipe 2.
  • the valve 11 is provided to allow an air inlet from the valve 9 into the hydraulic pipe 2 via the tube 8.
  • the valve 11 prevents leakage of liquid and gas when the pressure in the part of the pipe Hydraulic 2 upstream of the valve 5 is greater than the atmospheric pressure.
  • valve 9 if the valve 9 is closed, the introduction of air into the hydraulic pipe 2 is prohibited.
  • the valve 9 being open, the introduction of air takes place if the pressure in the hydraulic pipe 2 upstream of the valve 5 is less than atmospheric pressure.
  • valve 5 is open during a flow of fluid to the tank 1, in particular during pumping.
  • the valve 5 closes and remains closed when the upstream pressure becomes lower and remains lower than the pressure downstream of the valve 5 which is substantially equal to the pressure drops near the pressure in the tank 1.
  • valve 11 closes when the pressure upstream of the valve 5 becomes greater than the atmospheric pressure and the valve 9 closes to order of the control member 10 depending on the pressure in the tank 1 detected by the pressure sensor 6.
  • the pressure upstream of the valve 5 becomes greater than the pressure in the hydropneumatic reservoir 1, said valve 5 opens and the air present upstream of said valve 5 passes downstream and reaches the tank 1 by being stored in the upper part 1a. This increases the amount of air present in the tank 1.
  • valve 5 is disposed at an altitude lower than that of the lower part 1b of the tank 1, so that the introduction of air can not be done directly when the upstream and downstream pressures relative to the valve 5 in the pipe 2 are below atmospheric pressure.
  • the pressure sensor 6 may be in the form of a pressure switch located at the top of the tank. In this variant, the sensor is remote from the liquid, unlike other detection means such as electric tilt floats, electrodes, etc ... unreliable because of fouling or deposits.
  • the sensor 6 opens the valve 9 if the pressure during the emptying of the tank reaches a minimum pressure P set, corresponding to an air deficit. Stopping the pump 4 causes the emptying of the reservoir, the liquid it contains flowing downstream of the pipe 2 and the valve 5 being closed by the pressure exerted by the reservoir liquid. At the next start of the pump, the valve 5 opens under the pressure of the pumped water (and any air), allowing the flow to proceed towards the downstream, that is to say, in the reservoir and the pipe 2.
  • the pipe 2 going from the pump 4 to the tank 1 is preferably constantly rising.
  • the tube 8 is of short length, for example, a few tens of centimeters and can be a substantially vertical portion directed upwards from the hydraulic pipe 2.
  • the valve 9 can be of the solenoid valve type and is controlled by the organ electrical type control unit 10 forming a control interface between the pressure sensor 6 and the solenoid valve 9.
  • the pressure sensor 6 is then configured to generate an electrical signal which is transmitted to the solenoid valve 9, if appropriate after a treatment performed by the control member 10.
  • This embodiment requires an electrical connection and therefore a power supply that can sometimes be provided by a solar panel and a storage battery. This embodiment is particularly suitable in cases where the distance between the reservoir 1 and the valve 5 is relatively large.
  • the distance between the sensor 6 and the tube 8 can be quite long since the connection between them is only electrical. If it was necessary a timer could be provided to adjust at will the duration of opening of the solenoid valve or extend beyond the maximum pressure of first filling of the tank after its first emptying.
  • the pressure sensor 6 or pressure switch controls the opening of the valve to the pressure Pmini and closing it to a higher pressure. We can thus control the opening time and increase the accuracy of operation. Finally, if it is not desired to obtain a closing moment of the solenoid valve beyond the peak of maximum pressure, the closure of said solenoid valve by the pressure switch at a pressure less than or equal to the maximum pressure is possible.
  • the control member 10 may comprise a timer engaged at the opening of the solenoid valve 9 and causing the closure of said solenoid valve at a chosen instant according to the time elapsed since the instant of closure. Thus, after a calibration, it achieves excellent accuracy on the amount of air introduced.
  • a pre-inflation step may be provided by placing temporary water level sensors, for example in the form of a transparent vertical tube fixed on two valves provided in the wall of the reservoir, one in the air zone and the other in the water zone.
  • the two valves are open and compressed air is injected by one of them until the level of the air / water surface corresponds to the desired value, ie a static regime with line 2 full and pump to shutdown, in steady state of pumping.
  • the tube can then be removed in the end operation after closing the valves.
  • the commissioning of the hydropneumatic reservoir is therefore particularly simple.
  • the operation of the air introduction device can be fine-tuned in the field during the commissioning of the installation.
  • the air introduction device can be installed on hydraulic systems of wastewater or clear water.
  • the tube element 8 In the case of pumping clear water, with pumps without foot valve, the tube element 8 is provided with its valve 11 but without the solenoid valve 9. A solenoid valve is then connected directly to the pipe 2 near the pump. It opens and closes as would the solenoid valve 9 mentioned above in the text.
  • This embodiment is very suitable for frequent stop / start installations, especially for the discharge of wastewater.
  • the embodiment with closing delay of the valve is particularly suitable for installations with a large volume of pipe 2 between the valve and the water in the pumping tank and where the intervals between stopping and starting are such that they allow the total emptying, if necessary, of this upstream part of the pipe 2.
  • a pressure sensor 6 (which may be in the form of a pressure switch) located at the top of the tank.
  • Stopping the pump 4 causes the tank to drain, the liquid it contains flowing downstream of the pipe 2 and the valve 5 being closed by the pressure exerted by the liquid draining the tank.
  • the pumps are immersed in a tarpaulin and do not include a foot valve, so that when the pumping stops and if the valve 9 is open, the tube 8 allows at atmospheric pressure to be exerted throughout this tube, the small valve 11 then opening.
  • the pipe portion 2 located upstream of the valve 5 can begin to empty into the pump cover, through the pump 4.
  • the pump start causes, on the one hand, the closing of the valve 11, which prevents a rise of liquid in the tube 8 and, on the other hand, allows the introduction of air having taken the place of the drained liquid in the pipe 2 located upstream of the valve 5 which is now open.
  • This air is repelled and enters the tank equipped at its base with an air trap 12 (other forms of trap are possible), which partially or completely fill the deficit found. If this air supply is insufficient the operation will be repeated at the next pump stop.
  • the introduction of air is thus without requiring the installation of a compressor.
  • the sensor system detecting a minimum pressure, set at the end of emptying the tank is reliable, compared to a detection of lack of air steady state pumping by electrical level: pear, electrodes or probes not in contact with the water. Indeed, if the pressure in the tank at the end of the first filling after emptying is greater than the steady-state pumping pressure, this electrical detection will interpret it wrongly as an air deficit.
