Definitions

  • the present invention relates to a device for distributing and measuring liquefied petroleum gas, and in particular a safety box including a degasser and a differential valve and performing the functions of gas separation, maintaining of differential pressure, filtration, safety check valve and relief valve.
  • the devices currently used for the distribution and measurement of liquefied petroleum gas present risks of leakage and operational failures, due in particular to their complexity and their lack of mechanical rigidity.
  • the object of the invention is to remedy these drawbacks by assembling various means in a rigid safety box and by using a turbine meter with a helical rotor, said assembly having the advantage of compactness and of 'greater ease of implementation, combined with a reduced manufacturing cost and increased operational safety.
  • the housing safety capable of being sealed by the weights and measures department, is a compact box made of a steel of high mechanical resistance and is provided with tubular holes and cavities allowing to insert therein in particular a differential valve and a degasser, suitably connected to the inlet and outlet of the liquefied gas.
  • the device according to the invention comprises a filtration assembly 1, a pump unit 2, a regulation assembly 3, two safety solenoid valves 41 and 42, two check valves feet 51 and 52, a turbine meter 6, a control solenoid valve 7, a rupture valve 8, a flexible hose 9, a distribution gun 16, a safety casing 10, a dead-man contact 11, a gun contact 12, two emergency stop switches 13, a digital recorder 14 and a pressure gauge 15, connected between by pipes and connections which are not referenced, for the purpose of clarity of the description.
  • the liquefied petroleum gas follows the path starting from the filtration assembly 1 and passing successively through the pump unit 2, the regulation assembly 3, a safety solenoid valve 41, a foot valve 51, the housing 10, the measurer turbine 6, the housing 10, the control solenoid valve 7, the rupture valve 8, the hose 9 and ending in the distribution gun 16, the filtration assembly 1 being connected to the liquid part of a reservoir d 'not shown.
  • the second safety solenoid valve 42 not connected to the regulating assembly 3, is connected to the gaseous part of the same implantation tank, not shown.
  • the safety solenoid valves 41 and 42, the foot valves 51 and 52, the rupture valves 8, the emergency stop switches 13 and the pressure gauge 15 constitute the safety members of the device according to the invention.
  • the operating members consist of the control solenoid valve 7, the dead-man contact 11 and the gun contact 12. These members control the operation of the device, in normal operation, apart from breakdowns and anomalies whose detection is ensured by security organs.
  • the digital recorder 14 has the shape of a gallows and operates electronically, indicating on two displays the volume and the price of the liquefied petroleum gas distributed. For this purpose, it is connected to the turbine meter 6, which measures the flow rate of liquefied petroleum gas passing through it.
  • the safety box 10 comprises a pressure tap 21, a differential valve constituted by a bellows spring 22 and a movable piston 23 with axial displacement, a start from liquid 24, a safety valve 25, a gas return 26, a liquid inlet 27, a meter return 28, a meter departure 29, a degassing axis 30, a float assembly 31, a secondary meter return 32 , a non-return valve 33, a screen filter 34, a gas connection 35, and a secondary flow meter 36.
  • the pressure tap 21 allows the connection of the pressure gauge 15 to the housing 10 via a pipe 15 '.
  • the liquid outlet 24 is connected to the control solenoid valve 7.
  • the gas return 26 is connected to the foot valve 52 which, via a safety solenoid valve 42, is connected to the gas part of the reservoir d 'location, not shown.
  • the liquid inlet 27 is connected, through a foot valve 51 and a safety solenoid valve 41, to the regulating assembly 3.
  • the return of the meter 28 is connected to the outlet of the turbine meter 6, while its flow is connected to the input of the turbine measurer 6.
  • the secondary return of measurer 32 and the secondary departure of measurer 36 allow the lateral connection of the turbine measurer 6.
  • the differential valve consisting of the bellows spring 22 and the movable piston 23, is adapted to allow the fluid to pass only when the pressure difference between the flow of liquid 24 and the flow of liquid 27 is greater than that imposed by the bellows spring 22, preferably a bar.
  • This valve also has the function of preventing the return of the fluid in the event of high pressure downstream of the housing 10.
  • the safety valve 25 is calibrated and adapted to eliminate any overpressure in the system, which may be caused by the obstruction of the liquid return from the pump set 2, an incorrect adjustment of this return or an incident on this return. In the embodiment shown it allows the return of liquid to the reservoir implantation, through the gas return 26, but it can also, in a different embodiment, allow the evacuation of the product under pressure in the atmosphere.
  • the assembly consisting of the float 31 and the degassing axis 30 is adapted to prevent the turbine measurer from measuring the product in gaseous form.
  • the function of the non-return valve 33 is to keep the whole of the housing 10 under pressure when the system is put to rest and to avoid liquid returns in the event of an incident on the differential valve.
  • the screen filter 34 preferably has a spacing of 170 ⁇ m. It captures any solid particles contained in the liquefied petroleum gas passing through it.
  • the gas connection 35 allows the return of the gaseous fluid to the implantation tank.
  • the housing 10 also includes the gas evacuation device, the connection orifice connected to the gas phase of the fluid and the connection flanges for the inputs and outputs of the fluid and of the turbine meter 6.
  • It also includes a gas separator part consisting of the float 31 and the degassing axis 30.
  • a gas separator part consisting of the float 31 and the degassing axis 30.
  • the differential valve part comprises the movable piston 23 along its axis.
  • This movable piston 23 is subjected on its front face, that is to say on its underside in FIGS. 2, 3 and 4, to the pressure of the liquid leaving the turbine meter 6. It is subjected on its face rear, carrying the bellows spring 22, at spring tension, calibrated at operating pressure plus one bar. Consequently, the flow of the liquid to the liquid outlet 24 is only authorized when the pressure of the liquefied petroleum gas is approximately one bar higher than the vapor pressure of the liquefied petroleum gas contained in the implantation tank. .
  • FIGS 3 and 4 provide a better understanding of the operation in liquid service and in gaseous service of the housing 10.
  • the liquefied petroleum gas is represented by close points and the gaseous by separated points.
  • the liquefied petroleum gas arrives in the housing 10 through the liquid inlet 27 and successively raises the non-return valve 33 and the float 31.
  • the float 31 closes the gas return orifice of the degassing axis 30.
  • the liquefied petroleum gas can therefore pass through the orifice of the start of measurer 29. It returns from the turbine measurer 6 by the return of measurer 28.
  • the pressure of liquefied petroleum gas being greater than that of the gaseous plus a bar, the piston 23 is raised and allows the passage of the liquefied petroleum gas towards the liquid departure 24.
  • the liquefied petroleum gas arrives in the housing 10 through the liquid inlet 27 and raises the non-return valve 33.
  • the float 31 is not fully raised because there is formation of gaseous at a pressure higher than that of the gas of liquefied petroleum.
  • the orifice of the degassing axis 30 is not closed.
  • the degassing axis 30 therefore puts the piston 23 under gas pressure.
  • the upstream pressure and the downstream pressure of this piston 23 being equal, the differential valve cannot open and the flow rate of liquefied petroleum gas cannot be measured.
  • the operation of the device is as follows: when the distribution gun 16 is lifted, the price and volume indicators of the digital recorder 14 are automatically reset to zero, and, simultaneously, the pump set 2 is put into operation. Distribution is controlled by manual action on the dead man contact 11 controlling the opening of the control solenoid valve 7.
  • the liquefied petroleum gases are sent to the inlet of the gas separator of the housing 10, after having passed through the non-return valve 51 making it possible to keep the pressure in the housing 10 in the absence of operation of the pump set 2, and after having passed through the filter 34 of the housing 10, intended to eliminate any solid particles.
  • the gas separator is provided with a float 31 which ensures the automatic return of the gas to the gas phase of the implantation tank when there is formation of gas.
  • the liquefied petroleum gases exit the separator through the upper part of the housing 10, to pass through the turbine meter 6 which emits pulses as a function of the flow rate which it measures.
  • the liquefied petroleum gases then enter the differential pressure maintenance valve whose role is to maintain the liquefied petroleum gas in the turbine meter 6 at a pressure at least one bar higher than that of the saturated vapor.
  • the control solenoid valve 7 and a safety valve 8 At the outlet of the differential pressure valve is connected the control solenoid valve 7 and a safety valve 8, then, at the end of the hose 9, the distribution gun 16.
  • the hanging up of the dispensing gun 16 causes the opening of a switch constituted by the gun contact 12.
  • the opening of this switch cuts off the self-supply circuit of the reset relay of the digital recorder 14 and the power circuit of the pump set 2.
  • the main application of the device according to the invention is the measurement of the distribution of liquefied petroleum gas intended for automotive fueling and the pricing of this distribution.
