Definitions

  • the present invention relates to valves with electromechanical transducer type control, in which a electromagnet transforms an electrical control signal into a displacement or force applied to a sliding core.
  • the electromagnet comprises a fixed armature, integral with the frame of the device in which the electromagnet is inserted.
  • the frame in material sensitive to magnetic field, includes an axial channel in which slides axially a generally cylindrical core made of field-sensitive material magnetic.
  • the core slides in a first magnetic pole with a radial air gap, the second pole closing the axial channel and defining with the core a variable axial air gap.
  • An electric winding connectable to an external source of electrical energy, generates in the armature, and in particular in the axial channel between the two poles of the armature, a magnetic field tending to entrain the core in axial sliding in the axial channel along the longitudinal axis.
  • the core In its sliding, the core is guided by two elements to flexible radial blades comprising a peripheral part mounted fixedly on the fixed armature and connected by said flexible radial blades to a central part integral with the sliding core, to maintain the core at the distance from the walls of the axial channel while allowing its axial displacement according to an appropriate stroke between a first and a second position extreme axial.
  • the two elements with flexible radial blades are arranged on the same side of the axial channel, or inside the channel axial. This results in a relatively complex construction, as well as a relatively small sliding core travel between positions extreme axial, which does not allow good progressiveness of control.
  • Document US 4,954,799 A describes a continuously-controlled valve by sliding core electromagnet according to the preamble of the claim 1, with in particular a return spring, and with for objective of achieving a proportional linear movement of the nucleus sliding in the electromagnet according to the control current.
  • the document combines several complex means: pole pieces of particular shapes, a compression spring with an adjusting screw closing the axial channel, flat flexible blades placed very inside the coil, a magnetic flux adjustment socket.
  • the problem proposed by the present invention is to design a new electromagnet and sliding core valve structure, which either of simpler construction, and which ensures good progressiveness of the control device according to the electric current flowing through the electric winding.
  • a gate valve continuous control by electromagnet with sliding core includes the features of claim 1.
  • the flexible blades of at least one of the blade elements hoses are noticeably flat. This provision ensures a better radial rigidity, to guarantee a more effective maintenance of the nucleus in the position in which the magnetic field is maximum, preventing the magnetic forces from pressing the core radially against one of the magnetic poles.
  • a control device with electromagnet and sliding core comprises a fixed frame 1, provided with an electric coil 7 and an axial channel 3 which runs right through the electric winding 7.
  • the fixed frame 1 is integral with the frame 2 of the device in which she is willing.
  • a core 4 is slidably mounted in the axial channel 3.
  • the frame 1 made of a material sensitive to the field magnetic, is formed by a peripheral stirrup 9 whose ends are folded radially inward to form flanges of ends 10 and 11 each connecting to a first respectively coaxial tubular element 5 and a second coaxial tubular element 6, respectively forming a first pole 5 and a second pole 6 of the armature 1.
  • the frame 1 may consist of one or more assembled parts, comprising for example two opposite side members forming a double stirrup 9 being connected by the end plates 10 and 11. Poles 5 and 6 are shaped so that their respective inner faces 12 and 13 are opposite the core 4 and separated from it by an air gap generally thin radial.
  • the winding 7 is adapted so that when a current electric traverses it, it produces a magnetic field in the axial channel 3 between poles 5 and 6. Under the action of the magnetic field, the core 4 tends to move axially sliding in the axial channel 3 in the direction producing the reduction of the air gaps.
  • the nucleus 4 is made of a material sensitive to the magnetic field, and it is guided in sliding in the axial channel 3 by guide means capable of allow its sliding without introducing friction opposing this sliding.
  • the guide means according to the invention comprise a first element 14 with flexible radial blades, and a second element 15 with blades flexible radials, arranged respectively on either side of the ends of the axial channel 3, at a sufficient distance from the armature 1 for allow free flexion of the flexible radial blades during axial sliding of the core 4.
  • Each element with flexible radial blades such as element 14 comprises a peripheral part 16 mounted fixed relative to the frame fixed 1, that is to say integral with either the fixed frame 1 or directly of frame 2 of the device.
  • the element 14 with flexible radial blades comprises a central part 17 secured to the sliding core 4.
  • the part peripheral 16 is connected to the central part 17 by radial blades flexible 18.
  • the flexible radial blades 18 are arranged to present a great flexibility in the direction of axial sliding of the core such that represented by arrow 19, and to simultaneously present a large rigidity in the direction of the radial displacements of the core 4, so that keep the core 4 away from the walls of the axial channel 3, and in particular poles 5 and 6, while allowing its axial displacement along the I-I axis according to an appropriate stroke.
  • the flexibility of the blades 18 is chosen so that the appropriate stroke can be suitable for a possible displacement of the core 4 between two extreme axial positions of control illustrated respectively in Figures 1 or 7 and 2 or 8.
  • the core 4 is held by the two elements 14 and 15 with flexible blades axially offset on the core 4, excluding any sliding guidance in the axial channel 3.
  • At least three blades are provided hoses regularly distributed around the periphery of the central part 17 of element 14.
  • the flexible blades 18 are flat blades, enlarged in the transverse plane, and of reduced thickness in the axial direction of the nucleus 4.
  • the flexible blades include three blades, respectively 180, 181 and 182, having a general spiral shape around the longitudinal axis of the core.
  • the flexible blades have three blades 180, 181 and 182 each comprising at least one portion 184 substantially in an arc centered on the longitudinal axis of the core, and one or more generally radial connecting portions : in the example shown, the blade 180 comprises two portions in circular arc 184 and 185, respectively connecting to the crown peripheral 16 by a generally radial connection portion 186, and to the central crown 17 by a generally radial portion 187 of connection, and connecting to each other by a third portion generally radial 188 of connection.
  • each three flexible blades such as blade 180 also has two portions in arc of circle respectively 184 and 185, connecting one to the other by the generally radial portion 188, and connecting respectively to the peripheral crown 16 by the portion generally radial 186 and to the central crown 17 by the portion generally radial 187.
  • the respective flexible blades 18 of the elements 14 and 15 with flexible blades wind in the same direction around the axis longitudinal I-I of the device.
  • the flexible blades of the elements 14 and 15 print to the core 4, simultaneously with its axial translation, a slight rotation around the axis longitudinal I-I, promoting a harmonious deformation of the blades flexible 18.
  • elements with flexible blades such as element 14 can be formed from a flat steel disc or other material, in which lights are cut to form the flexible blades as shown.
  • the elements 14 and 15 with flexible radial blades 18 can advantageously have a diameter significantly greater than that of the axial channel 3.
  • the peripheral crown 16 of elements 14 and 15 can be fixed directly to the frame 2, thus having a diameter at least equal to the outside diameter of the frame 1. We favor thus the flexion possibilities of the flexible blades, to increase the admissible axial travel of the core 4.
  • Figures 1 and 7 illustrate a device according to the invention in a first extreme axial position.
  • the flexible blades 18 in the absence of magnetic field produced by the fixed armature 1, the flexible blades 18 have a permanent deformation in bending in the direction I-I of axial displacement of the core 4 in a first direction 20.
  • the core 4 is relatively far from the second pole 6 of frame 1.
  • the permanent bending deformation of flexible blades 18 in first extreme axial position may result from preforming the flexible blades 18.
  • the permanent bending deformation of the flexible blades 18 in first extreme axial position may result from the thrust of an axial spring 31 urging the core 4 towards its first extreme axial position.
  • the core 4 moves axially in the direction 19 opposite to said first direction 20 until within a second extreme axial position as illustrated in FIGS. 2 and 8, position in which the core 4 has approached the second pole 6 of the frame 1.
  • the elements 14 and 15 with blades flexible are deformed as illustrated in figure 2, by bending flexible blades 18 of each element.
  • the core 4 can move while remaining permanently away from poles 5 and 6 of armature 1, so that no friction disturbs the axial displacement of the core 4.
  • the flexible blades 18 of at least one of the elements 14 and 15 with flexible blades are substantially flat, that is to say in a plane generally perpendicular to the axis I-I of the device.
  • the two elements 14 and 15 are substantially flat. We thus improves the radial rigidity of the blades in this second position extreme axial where the core undergoes the maximum mechanical stress under the effect of the maximum magnetic field generated by the coil 7.
  • the first end of the core 4 is cylindrical, and slides in the first pole 5 whose respective inner surface 12 is cylindrical. So the first pole 5 defines with core 4 a first radial air gap constant, independent of the axial position of the core 4 in the axial channel 3.
  • the second end of the core 4 is shaped like a cone 22, to cooperate with a part conical corresponding 23 of the second pole 6 in which it comes to commit.
  • the second pole 6 thus defines with the core 4 a second radial air gap which decreases as a function of the axial displacement of the core 4 of the first to the second extreme axial position.
  • Axial displacement of the core 4 gradually modifies the air gap 21 between the cone 22 of the core 4 and the conical part 23 of the pole 6. It is thus possible to produce a progressive displacement of the nucleus in the presence of the magnetic field generated by the winding 7.
  • the first pole 5 also has a cylindrical inner surface defining a first constant air gap, as in the previous embodiments.
  • the second pole 6 has a cylindrical interior surface, and cooperates with a portion of core 4 of variable diameter, defining a second variable radial air gap.
  • Another alternative may be the presence of two poles 5 and 6 with cylindrical internal surfaces opposite parts cylindrical of core 4, defining two constant radial air gaps independent of the axial position of the core 4.
  • the control device can be associated with shutter means, to constitute an electrically controlled valve continuously.
  • the core 4 carries or constitutes by itself a obturation element allowing to modify the open section of a channel of fluid conduction as a function of the axial position of the core 4 in the frame 1.
  • Figure 3 shows an embodiment of such continuously electrically controlled valve, comprising a device for solenoid control identical to that of FIGS. 1 and 2, in which the same elements have been identified by the same reference numerals. he the same is true of FIGS. 7 and 8, which represent another mode of realization of such a continuously electrically controlled valve.
  • Core 4 carries a shutter element 24 coaxial of revolution coming to be housed in the opening 25 of a seat 26 coaxial with a conduction conduit fluid.
  • the closure element 24 advantageously has a form of revolution gradually tapering towards its end 27, so that the closure element 24 produces a continuous variation of the section open the fluid conduction pipe depending on the position axial of the core 4 and of the closure element 24 in the seat 26.
  • An elastomer seal 28 can be interposed between a facet 29 front of the seat 26 and a front 30 of the element shutter 24, to ensure a tight shutter when the device is in the first extreme axial position illustrated in FIGS. 1, 3 and 7.
  • the core 4 is stressed in axial translation by means elastic such as a compression spring 31, pushing it towards its first extreme axial position shown in FIGS. 1, 3 and 7, with against the stress exerted by the magnetic field generated by the winding 7.
  • the spring 31 must have a return force greater than the axial force possibly exerted by the elements 14 and 15 with blades flexible, and less than the axial stress produced on the core by the magnetic field generated by the coil 7.
  • the core 4 made of magnetic material occupies only part of the length of the channel axial 3. Its first end, fixed to the first element 14 with blades flexible, has an axial extension 40 force-fitted into a corresponding axial bore of the part forming the closure element 24.
  • the second end of the axial core 4 has a reduced diameter slightly, and has a threaded axial bore 41 into which is screwed a tie rod 42 for connection with the second element 15 with flexible blades.
  • a barrel 43 is engaged on the tie rod 42 between the second end of the core axial 4 and a first face of the central part of the second element 15 to flexible blades.
  • a nut 44 is screwed onto the end of the tie rod 42 and comes to bear on the other face of the central part of the second element 15 to elastic blades.
  • the spring 31 is a compression spring engaged between the nut 44 and an end flange 45 of the frame 2.
  • the invention finds particular applications in the gas flow control.
