Definitions

  • ABSTRACT A valve arrangement wherein the electromagnetically controlled core carries yieldingly a valve member rigid with a control rod. Said core is urged elastically in a direction opposed to its electromagnetic control so that the valve member releases the opening controlled by it. Said rod projects outwardly to provide both a visual indication and a positive control of said valve member when required.
  • a push button surrounding the rod is urged elastically against an abutment on the latter in order to prevent the valve member from releasing its seat under the action of its electromagnetic control. unless the push button is held in a depressed position away from the abutment.
  • Electromagnetically controlled valve arrangements for fluids which include a movable magnetic core subjected to a returning force and adapted to be shifted under the action of a magnetic field produced by a winding fed by an electric current, said core carrying at least one valve member cooperating with a seat so as to open and close a fluid channel as required and according to the position assumed by the core, the core being manually controllable from the outside of the valve arrangement by a rod the axis of which is parallel with the direction of movement of the core and which extends through the seat so as to act on the core.
  • said rod may be shifted so as to engage the valve member on the core or the actual core thereby to shift the latter and lock the valve arrangement in a predetermined position.
  • the present invention has for its object to check whether the movable core is freely operative and to allow a handoperated shifting of said core without it being necessary to dismantle the valve arrangement, for instance in the case of a failure of electric current or for adjustments outside the operative cycles.
  • the manual control means may include two parts of which one is connected with the core through the agency of the valve member, while the other is free and may be readily held fast in either of two extreme positions.
  • FIG. 1 is a cross section of a first embodiment provided with a return pipe for the fluid conveyed.
  • P16. 2 is a similar cross section of a second embodiment comprising no return pipe for the fluid conveyed.
  • FIG. 3 is a cross section through line ill-Ill of FIG. 2.
  • the valve arrangement includes a body 1 provided with threaded bores 2 and 3 which allow connecting said body with input and output pipes for the fluid to be controlled by said valve, said fluid being gasiform or liquid.
  • the body .1 is also provided with a further threaded bore 4 inside which is screwed a support 5 carrying a tube 6 made of a non-magnetic material such as brass. Said tube is slidingly engaged by a movable ferromagnetic core 7. Said core 7 is subjected to the pressure of a spring 8 urging it towards the seat 9 adapted to be closed by a valve member 10 floatingly carried by the core 7 with the interposition of the spring Ill. The core 7 can rotate freely inside the tube 6, friction, chiefly that exerted by the spring 8, being negligible.
  • the core 7 is provided with at least one longitudinal slot 112 and carries at its upper end another valve member 1.3 constituted by a small disc of a yielding material, such as an elastomer, resting on a metal plate 14.
  • Said plate M which is urged upwards by a spring is provided along its periphery with a stud 16 engaging the slot 12 in the core 7, so as to prevent the valve member 13 from rotating with reference to the core and to allow thus a screwing of the upper end of the rod 21 rigid with said plate 14 inside the control knob 25.
  • the upper end of the tube 6 encloses a stationary cylindrical ferromagnetic member 18.
  • the tube 6 surrounded by a casing enclosing a winding 19 fed by an electric current and acting on the ferromagnetic core 7.
  • the metal plate 14 carrying the valve member 13 is rigid with a rod 21 extending in the direction of movement of the core 7.
  • Said rod passes through a push button 22 slidingly fitted inside a hollow cylindrical extension 23 of the ferromagnetic member 18.
  • Said push button 22 is subjected to the action of a spring 24 urging it against the cylindrical knob 25 screwed over the upper end of the rod 211, said knob 25 being adapted to rest through its lower end on the inner shoulder 26 of the push button 22.
  • a packing 27 is inserted between the rod 21 and the knob 22 so as to ensure fluidtightness.
  • the outer surface of the push button 22 is provided with a longitudinal groove 28 cooperating with a lug 29 cut out of the ferromagnetic member 18 and projecting inwardly of the latter.
  • Said groove 28 opens into an arcuate peripheral groove 35]! forming with it a bayonet system locking the push button 22 in its lower position when the lug 29 is. caused to enter said groove Ell.
  • a port 17 provides a connection between said groove 30 and the axial passage formed in the push button 22.
  • the cylindrical extension 23 of the ferromagnetic member i8 is furthermore surrounded by a sleeve 31 locked in position over the casing 20 by a nut 32.
  • the sleeve is provided with an inner peripheral groove 33, into which there opens an outer pipe 34', collecting the recovered fluid which flows towards the exhaust after opening of the valve member 13.
  • the seat 9 When the core 7 is in its upper position as illustrated, the seat 9 is left open by the valve member ltl so that the threaded bores 2 and 3 and consequently the input and output pipes communicate, while the upper valve member l3 closes the axial passage formed in the ferromagnetic member l8 by engaging the seat 35 on the latter.
  • valve member lli closes the seat Q while the threaded bore 3 opening into the output pipe communicates with the collecting pipe 34 through the slot H2 in the core 7, the axial passage in the ferromagnetic member t8, the port 17 and the annular groove 33.
  • the spring 24 can no longer urge the core 7 upwardly and consequently said core is urged downwardly by the spring 8 and closes the opening in the seat 9.
  • the rod 21 is free to slide upwardly in said button for allowing a shifting of the core 7 under the control of the current feeding the winding 119.
  • the ferromagnetic member 18 is magnetized and attracts the core 7, so as to shift it upwardly in antagonism with the spring 8.
  • the producer can-have in stock a number of valve, arrangements carrying no winding so that each valve can be provided with the desired winding at the moment of its handing over to the buyer who has merely to state the voltage available to him for the energization of the reference to the core 7, it is possible to manually control the latter through depression of the rod 21 or of the push button 22. This may be of considerable advantage whenever the latter is jammed by impure particles carried by the fluid. It should also be remarked that it is impossible to remove the push button 22 without completely dismantling the valve arrangement since it is necessary to first release the cylindrical knob 25, this being possible only by holding fast the core 7 against rotation. so as to lock the rod 21 in position during the unscrewing of the knob 25.
  • the fluid controlled by the valve arrangement according to FIG. 1 is valueless and constituted by air, it is not necessary to provide the packing at 27 nor the sleeve 31 with its collecting pipe 34 adapted to recover fluid.
  • said sleeve may be replaced in the case of such a valueless fluid by a mere spacing block allowing a clamping in position of the casing 20 enclosing the winding 19 by the nut 32, the fluid escaping then freely through the port 17 opening into the groove 30.
  • FIG. 2 The embodiment illustrated in FIG. 2 is practically identical with that illustrated in FIG. 1, except for the design of the upper end of the rod 21 and of the push button 22 and for the omission of the sleeve 31.
  • this second embodiment adapted for operation with an electric energy reduced to a minimum.
  • the packing 27 between the push button 22 and the rod 21 has been omitted so as to reduce friction during the shifting of the rod 21.
  • the central opening of the push button 22 is closed by a threaded plug 36 clamping in position a packing 37 In such an embodiment.
  • the cylindrical knob 25 capping said rod includes a section 38 formed by a permanent magnet while a ring 39 of ferromagnetic material is slidingly fitted over a nonmagnetic sleeve 40 surrounding the push button 22.
  • the ring 39 is constrained to follow the movements of the magnetic section 38 and provides a visual indication of the position of the core 7.
  • the part of the sleeve 40 over which the ring 39 is adapted to slide carries two spaced annular strips which are covered and uncovered in alternation by the ring 39, so as to further the reading of the location of said ring, for instance by colour.
  • FIG. 2 An advantageous modification of the embodiment illustrated in FIG. 2 allows a locking of the valve in a desired position.
  • it is sufficient to provide an arrangement locking button 22 as required in any one of three predetermined positions.
  • the valve arrangement electrically.
  • the valve member 13 is closed as in the case illustrated in FIG. I.
  • the threaded plug 36 engages the rod 2.1, so as to urge the core 7 downwardly thereby to hold the valve member on its seat 9.
