Definitions

  • the present invention relates to a solenoid valve of the type comprising a valve body provided with a conduit inlet, outlet conduit and means adapted to selectively activate communication these two conduits. It applies in specific to nitrogen inerting / pressurization of bottles containing a flat liquid, for example juice fruits.
  • the technique of inerting / pressurizing containers using nitrogen is to deliver to each container scrolling on a conveyor, after filling, a dose liquid nitrogen.
  • the response time of the solenoid valve should be on the order of a few milliseconds.
  • the solenoid valve coil must not not cause liquid nitrogen to enter the substantial heat, to prevent the formation of gas plugs disrupting the exit of nitrogen doses liquid.
  • the invention aims to provide a solenoid valve to very low response time especially suitable for cryogenic applications, for example for those mentioned above.
  • the invention relates to a solenoid valve of the aforementioned type, characterized in that the valve body includes at least two separate passages that connect the inlet duct to the outlet duct, and in that the actuation means comprise several actuators each of which is adapted to selectively seal one of said passages.
  • the packaging installation shown on Figure 1 comprises a conveyor 1 on which bottles 2 scroll in a single file, in the direction of arrow F.
  • the bottles pass successively under a filling station 3 with liquid 4, under a device 5 to supply each bottle with a dose of nitrogen liquid, then under a station 6 for closing the bottles by means of a capsule 7.
  • the apparatus 5 includes a tank of liquid nitrogen 8, suitably thermally insulated and equipped with all the classic accessories for his supply of liquid nitrogen and its venting, a dispensing head 9, and a transfer line 10 vacuum insulated which connects the tank to this head.
  • the pipe 10 is vertical, and the tank 8 is raised and possibly under pressure, so that driving is in charge.
  • Head 9 ( Figures 2 to 5) includes a solenoid valve 11 housed in a case 12. The space remaining free in this the latter is filled with a thermal insulation material, of which a part has been illustrated at 13 in FIG. 2.
  • the solenoid valve 11 essentially comprises a body valve 14, four actuators 15, an inlet nozzle 16 and a blowing tube 17.
  • the body 14 ( Figures 4 and 5) has the general shape a parallelepiped block extended upwards by a inlet manifold 18.
  • the bore of this manifold is ends approximately halfway up the block, which is provided four bores 19 with coplanar and horizontal axes arranged at 90 ° to each other.
  • the entrance to each bore 19 is counterbored at 20, and an annular seat 21 is defined at the bottom of each counterbore.
  • Tubing 18 ends above the bores and communicates with the chambers 22 defined at the bottom of the counter bores, by four openings 23.
  • a conduit exit 24 goes down from the intersection point of bores 19 and is defined, in its downstream part, by a outlet pipe 25, projecting from the body 14.
  • the pipes 18 and 25 have a common vertical axis X-X, the inner diameter of tubing 25 is much less than that of tubing 19.
  • the body 14 also has, between two bores 19 and in the same horizontal plane, an end leads 26 to counterbored entry.
  • Each actuator 15 is a coil whose core carries at its end a shutter 27 adapted to cooperate with the corresponding seat 21.
  • the actuator is provided with a threaded end piece 28 for fixing in the counterbore 20.
  • the four coils are connected via wires 29 to a connection 30 of the housing 12.
  • the inlet nozzle 16 is a material tube thermally insulating, namely Teflon, which slides in tubing 18. Its upper, flared end is elastically biased upwards by a bellows metallic 31 and internally has a shape funnel 32.
  • valve body is wedged in the housing 12 at by means of insulating shims 33 which line the walls inside of the case.
  • the lower wedges and peripheral are provided with heating elements 34 to incorporated electrical resistance.
  • the tube 17, which forms an expansion loop at the inside of the case, is fixed by its downstream end in the inlet of bore 26 and through its upstream end in a gas inlet fitting 35 provided on the housing.
  • the housing 12 has a cylindrical shape around the body 14, then converges upwards around the nozzle 16, then is extended upwards by a tube 36. This last connects to the outside pipe of line 10 by a flange and hose clamp connection 37, with interposition of a centering ring 38 and a seal sealing 39.
  • the inner pipe 40 of the pipe 10 extends beyond the downstream obturation device 41 of the pipe, crosses the tubing 36, and carries at its end a nozzle spherical 42 in stainless steel. Under the effect of the bellows 31, when the connection of the dispensing head 9 to the pipe 10 is made, the end piece 42 is applied with a reliable linear contact in the input funnel 32 of the nozzle 16.
  • control means 43 Figure 1 put sequentially and cyclically the actuators in open position, synchronization being performed at from signals supplied by sensors 44 which detect the passage of successive bottles 4.
  • pressurized gas is sent via tube 17 and the bore 26 at the inlet of the outlet conduit 24, which isolates a precise dose of liquid nitrogen equal to the volume of this outlet duct and expels it down.
  • This gas propellant can in particular be nitrogen gas at ambient temperature.
  • the distribution head is fully assembled, all along the liquid nitrogen circuit, of compatible materials with liquid nitrogen and with cleaning products from the installation.
  • the valve body 14 is made of stainless steel
  • nozzle 16 is in Teflon
  • the shutters are in "Buna".
  • the actuators 15 can be constituted by commercial components of low power (at most 10 W) to limit heat gain.
  • the presence of the elements 34 in the housing 12 prevents any formation of condensation or frost, especially in the region of liquid nitrogen outlet.
  • the variant of solenoid valve can be used three actuators whose bodies 14 are shown in the Figures 6 and 7.
  • the axes of the three actuators are new coplanar and horizontal, and they're arranged in star at 120 ° from each other ( Figure 7).
  • the areas of the openings 33 have been increased, in order to provide more free passage permanent with liquid nitrogen from inlet pipe 18 to chambers 22.
  • These openings 23 thus have a bean, as seen in Figure 6.
  • outlet pipe 24 is internally threaded to fixing an interchangeable outlet nozzle (not represented).
