Definitions

  • the invention relates to the field of retail distribution of hydrocarbons such as petrol and diesel. More precisely, it relates to controlling the distribution of the hydrocarbon as a function of the gas content of the latter.
  • a valve device is used, upstream of the oil dispensing lance, to possibly stop the flow of the hydrocarbon towards the end of the lance. This valve is calibrated so that it closes when the delivery pressure drops due to the presence of an excess of gas in the hydrocarbon.
  • This type of device comprises the following elements downstream of the hydrocarbon storage tank.
  • a pump extracts the hydrocarbon from the storage tank to send it to a degassing device.
  • the latter is generally of the vortex type.
  • the degassed hydrocarbon is taken from the periphery of the degassing device, tangentially to it and is sent in the direction of the valve device.
  • This type of device using a control valve is not always effective in the event of excess gas. This excess is due to the fact that if the gas content at the inlet of the degassing device is too large, the latter is saturated. In addition, its operation can be random.
  • the object of the present invention is to remedy these drawbacks and to propose a control system for the valve device, making it possible to very significantly increase the reliability of the operation thereof and to precisely regulate the level of closure of the control valve. , depending on the gas content.
  • the main object of the invention is a hydrocarbon distributor comprising: A pump to extract the hydrocarbon from a storage tank; A vortex type degassing device comprising an inlet pipe connected to said pump, an outlet pipe and an axial auxiliary outlet for withdrawing a fraction of the hydrocarbon enriched in gas, a lance for distributing the hydrocarbon ; A control valve mounted between said lance and the outlet of said degassing device; and A device for controlling said control valve as a function of the gas content in the hydrocarbon, comprising, a venturi system mounted on said auxiliary outlet and means for controlling the closing of said control valve as a function of pressure in said venturi system.
  • the means for controlling the control valve comprise: A control valve which is closed when the pressure at the neck of the venturi system is greater than a predetermined value and means for causing the closure of the control valve when said control valve is closed.
  • the device according to the invention mainly comprises a pump 11, a degassing device 13, a control valve 21 of a lance 50 and control means 19 of the control valve 21 as a function of the gas content of the hydrocarbon delivered by the degassing device 13.
  • a pump 11 brings the hydrocarbon, via an inlet pipe 12, to a degassing device 13.
  • This mainly consists of a body cylindrical 14, at a first end 15 from which the inlet pipe 12 tangentially terminates.
  • the discharged hydrocarbon arrives tangentially in the cylindrical body 14 in a vortex-type vortex movement.
  • an outlet pipe 16 is placed, in an identical manner to the inlet pipe 12, that is to say tangentially to the cylindrical body 14. In this way, by the movement of vortex, the hydrocarbon containing the least gas and being the heaviest, evolves at the periphery of the interior of the cylindrical body 14.
  • the outlet pipe 16 therefore withdraws, at the periphery of the main body, the practically degassed hydrocarbon.
  • An auxiliary outlet 24 of the degassing device 13 is placed at the second end 9 of the latter and in the center of the cylindrical body 14. In this way, the excessively gaseous hydrocarbon exits through this auxiliary outlet 24, which ends up inside a recovery tank 9 for recycling the hydrocarbon.
  • control means 19 are installed between the degassing device 13 and the control valve 21 to better take into account the pressure of the hydrocarbon, therefore the gas content in this one. These control means 19 will be described later in the description.
  • the outlet pipe 16 leads to the control valve 21 mainly comprising a control body 20, inside which is placed a control valve 22 which comprises a first and a second face.
  • the latter is slidably mounted inside the body 20 which can thus take at least two longitudinal positions, the first closing off by its first face the connection between the inlet 17 of the outlet pipe 16 and the pipe 18 of the lance 50.
  • the second position of the control valve 22 leaves open the connection between the inlet 17 of the outlet pipe 16 and the pipe 18 of the lance 50.
  • a first spring 44 bearing on the bottom of the control body 20, maintains the control valve 22 in the first position.
  • the control means of the control device mainly comprise a venturi 25 and means for controlling the closing of the control valve 22 as a function of the pressure in the neck of the venturi 25.
  • the latter comprise a servo or exhaust pipe 36 and a servo valve consisting of a servo body 33, inside which is a valve servo 32.
  • the venturi 25 is placed at the auxiliary outlet 24 of the degassing device 13, its outlet 26 discharging into the recovery tank 9.
  • a pipe 28 is formed in the venturi 25, perpendicular thereto and opening into the neck of the venturi 25.
  • the control body 33 is placed opposite the outlet of this pipe 28 of the venturi 25, an internal chamber 30 of the control body 33 being in communication with the neck of the venturi 25.
  • a orifice 42 connects the internal chamber 30 with the outside.
  • the control line 36 connects the control volume or control chamber 38 of the control valve 21 with the control body 33.
  • the control valve 32 is slidably placed inside the control body 33, so as to be able to obstruct, in a first position, the control line 36 opening into the chamber 30 of the control body 33. In a second position, this valve 32 leaves the control line 36 and the chamber 30 in communication
  • This servo valve 32 is slidably mounted inside the servo body 33 in a sealed manner.
  • a second spring 35 is placed behind the control valve 32 to allow the latter to ensure complete closure of the control line 36 by pressing against a seat 34 of the control body 33.
  • a counting device can be placed on this outlet lance 18.
  • the operation of the control device according to the invention is as follows.
  • the density of the fluid withdrawn by the auxiliary outlet 24 and the venturi 25 is high.
  • the vacuum at the neck of the venturi 25 and the pipe 28 of the servo body 33 is therefore significant.
  • the consequence of this depression is to keep the servo valve 32 in the open position, that is to say in a position leaving the servo line 36 and the orifice 42 of the servo body 33 in communication.
  • the fluid penetrating through the outlet pipe 16 into the control valve 21 also partially penetrates into the control volume 38. It can therefore also flow through the control pipe 36 towards the chamber 30 of the control body 33 , from which it leaves through the orifice 42 communicating with the outside.
  • the pressure in the control volume 38 of the control valve 21 is therefore reduced and practically equal to atmospheric pressure. Consequently, the control valve 22 remains in the open position, and allows the flow of hydrocarbon in the direction of the lance 50.
  • the gas content in the hydrocarbon is high, there is a large difference between the densities of the fluid evolving at the periphery of the cylindrical body 14 of the degassing device 13 and the fluid evolving at the center of the cylindrical body 14, the latter being the lowest.
  • the fluid flowing in the venturi 25 therefore has a lower density, the vacuum generated by this venturi 25 is reduced.
  • the pressure in the pipe 28 of the venturi 25 therefore increases.
  • the second spring 35 of the servo valve 32 being calculated to react above a determined vacuum value, corresponding to a rate of gas in the hydrocarbon, the servo valve 32 is forced against the seat 34 of the body servo 33. It therefore blocks the passage of the fluid from the servo line 36 to the orifice 42 communicating with the outside.
  • control valve 32 being closed, the pressure in the control volume 38 gradually becomes equal to the pressure in the line 16, due to the leaks from the control valve 22 and from the conduit 40 in the control valve 22.
  • the pressure therefore becomes substantially equal on either side of the control valve 22 which closes under the effect of the first spring 44.
  • the lance 50 is no longer supplied.
  • the reopening of the control valve 22 can only occur if the servo valve 32 opens, that is to say if the gas content falls below the determined gas rate.
  • the control valve 32 opens, the control volume 38, placed in communication with the orifice 42, is gradually brought to atmospheric pressure.
  • the pressure in the outlet pipe 16, which is much higher than atmospheric pressure acts on the periphery 22a of the first active face of the control valve 22, which is sufficient to compress the first spring 44 and cause the opening of the control valve 22.
  • the gas content is measured in line 16. In fact, the presence of the excess gas lowers the pressure of the hydrocarbon-gas mixture, which causes the control valve to close. 22.
  • the gas content is determined at the auxiliary outlet 24 of the degassing device 13. This gas content of the fluid at the auxiliary outlet 24 is therefore representative of the gas content in the outlet pipe 16, but with a very significant amplification of this content.
  • the auxiliary output 24 being axial, it takes fluid from the area of the vortex degassing device where it is most enriched in gas.
  • the springs 44 and 35 can be calculated in advance, so that the control valve 21 and the servo means can react to determined pressure values corresponding to a determined rate of gas in the hydrocarbon, the device according to the invention can be applied to different hydrocarbon distribution installations, and under different conditions of use.
