Definitions

  • the present invention relates to a rotary valve with full passage.
  • full-flow rotary valves have a spherical, cylindrical or conical rotation, having a round lumen.
  • the seals are mounted on the valve body and rub on the turn while it is rotating.
  • valves with parallel seats with two covers
  • a movable assembly carries two covers which come to bear on seals to ensure closure.
  • the lids undergo two successive movements, first a movement in a direction parallel to that of the pipe carrying the valve, so as to separate the lids from their seats, then a movement in a direction perpendicular to the previous one so as to completely clear the passage through the valve.
  • Such embodiments make it possible to obtain a long-lasting seal, because the cover is not subjected to any friction against its seat and its seal.
  • they require relatively complicated mechanical devices.
  • the object of the present invention is to provide a valve which combines the simplicity of a rotary valve with sealing and duration characteristics which have so far been obtained only with valves with parallel seats, with two lids.
  • US Patent 2,531,759 describes a ball valve in which the turn carries the cover and drives it in its rotation: when approaching the closed position, the edge of the cover abuts on the edge of the seal, and a cam forming part of the turn then pushes the seal against this seal.
  • Such an arrangement can lead to rapid deterioration of the seal, because the cover does not move perpendicular to its plane.
  • Patent FR 1,593,350 describes a valve of similar type, but in which the cam, which pushes the cover, is not part of the turn, but is part of an intermediate piece carried by the turn with an elastic means interposed.
  • a special stop is provided to stop the seal outside the area which constitutes the seal. Such an arrangement is likely to spare the seal and increase its duration, but this gain is limited because the movement of the cover at the time of closure is still a pivoting around a point located near the plane seal.
  • the valve according to the present invention has characteristics in common with each of the two types of valves, since it comprises both a full-flow turn and lids moving perpendicular to their seats.
  • the invention relates to a rotary valve with full passage, as defined in claim 1.
  • the zone of action of the intermediate piece on the cover is located in the vicinity of the axis of the latter. .
  • the valve according to the invention can allow rational movement of the cover at the time of closing, thanks to the fact that the cover can be guided in the desired direction, and in particular have a rectilinear movement, perpendicular to its plane, which, as we saw above, is not possible when it is in abutment at this time, because its only possible movement is then a pivoting around the abutment point, which is in its plane or close to this plane, and which is only possible in an approximate manner when it is carried by connecting rods, despite the complication of the latter system.
  • the guide of the cover can be obtained in a simple way by providing that the turn carries the cover through a housing forming part of said turn and in which a stud carried by the internal face of the cover slides freely in the direction of the axis of the cover.
  • the cover further comprises a peripheral rib which cooperates with two circular guides carried respectively by the bottom of the body and by the cap in order to limit the amplitude of the pivoting of the cover coming from the play of the stud in its housing.
  • the turn carries the cover by means of holding and driving stirrups which penetrate into a peripheral groove of the cover with sufficient play to allow its movement under the action of the intermediate piece.
  • stirrups which penetrate into a peripheral groove of the cover with sufficient play to allow its movement under the action of the intermediate piece.
  • it avoids having a part sliding in a nozzle, which can be troublesome in certain particular cases of temperature or nature of the bodies, but at the cost of a complication of the shape of the turn.
  • the cover is carried directly by the intermediate piece while being able to move relative to this piece along the axis of the cover.
  • the means for holding the cover are provided to allow the cover to rotate about its axis while rolling on the body during the rotation of the turn, and the body or the cap.
  • the valve comprises a circular guide which cooperates with the edge of the cover to drive it in rotation when the turn is itself in rotation, that is to say that if the cover has a stud penetrating a housing, this stud has a circular section and the same axis as the cover, and if the cover is held by stirrups penetrating a groove, the latter has the shape of a complete circle of the same axis as the operculum.
  • an elastic means exerts on the intermediate piece a force tending to maintain it in the rest position, this force being overcome by that exerted by the stop for the passage into the active position, and advantageously the valve comprises an additional spring intended to facilitate the recoil of the cover towards the turn when opening. This is avoided if any risk of unwanted friction of the cover against the valve body.
  • the valve body 1 comprises a cap 2, a bottom 3 and two end pieces 4, to be welded on pipes.
  • the turning 5 of generally tubular shape, carries at its upper part an operating rod 6 which crosses the cap 2 of the body, and, at its lower part, a pivot 7, coaxial with the operating rod, and which penetrates into a housing 8 of the bottom 3 of the body. It supports two lids 10 provided, towards their periphery, with a seal 11 intended to cooperate with a corresponding seal 12 secured to the body.
  • the turn comprises a housing 14 in which a stud 13 carried by the internal face of the cover slides freely in the axial direction of the cover, which ensures the drive of the cover by the turn during the rotation of that -this.
  • the cover further comprises a peripheral rib 15 which cooperates with a circular guide 16, carried by the bottom 3 of the body, and a similar guide 17, carried by the cap 2.
  • the role of the guides 16, 17 is to limit the amplitude of the upward or downward pivoting of the cover in a play of the stud 13 in its housing 14 during the rotary movement of the turn, and of preventing a defective engagement of the cover during
  • the intermediate piece 19 has the general shape of a corner, having a central recess. More specifically, it comprises a body 20 extended by two wings 21 which are connected at their opposite end to the body 20 by a cross member 22.
  • the internal face 23 of the wings 21, that is to say that which faces towards the center of the turn 5, is oblique, so that the width of the wings 21 decreases away from the body 20; this internal face 23 constitutes a cam surface which comes to bear on an oblique boss 24 integral with the turn 5.
  • the external face of the end of the wings 21 and of the cross-member 22 consists of a bearing surface 25 which comes into contact, during closing, with the internal face of the cover 10 in the central region of this cover.
  • a spring 26, working under compression, is placed between the wings 21 and bears, on the one hand, on the body 20 of the intermediate piece, and, on the other hand, on a boss 27 of the turn 5.
  • This boss is crossed by the housing 14 of the stud 13, and its upper part enters between the wings 21 and constitutes a stop for the crosspiece 22, thus limiting the stroke of the spring 26.
  • the valve body 1 carries a boss 28 on which the end 29 of the body 20 of the intermediate piece comes to bear at the end of the rotary movement of the turn 5 in the closing direction.
  • the surface of the end 29 of the body 20 which comes into contact with the stop 28 is rounded so as to allow a slight pivoting in a direction perpendicular to the axis of turning rotation.
  • the operation of the valve is as follows: in the open position, the turn 5 is aligned with the nozzles 4 so as to provide the fluid with a passage of uniform section, the lids 10 are substantially in a vertical plane parallel to the passage of the fluid, the intermediate piece 19 is in the rest position, that is to say it is pushed by the spring 26 which separates it from the boss 27, is held in position by the support of the cross-member 22 on the same boss 27 As a result, the intermediate piece 19 exerts no pressure on the cover 10. If it is desired to move to the closed position, the rotary 5 is actuated using the rod 6, so as to do so rotate on its vertical axis.
  • the lids 10 are driven in the movement by the stud 13, their relative position relative to the turn 5 being maintained, with a slight play, thanks to the guides 16, 17 and to the stops 18.
  • the intermediate piece 19 is driven with the turn 5
  • the end 29 of the intermediate piece comes into contact with the stop 28 which stops it.
  • the oblique boss 24 acts on the cam surface 23 and causes the intermediate piece to tilt which, by means of the bearing surface 25, moves the cover 10 away from the turning 5 and brings its lining 11 to cooperate with the lining 12, carried by the body, to ensure sealing.
  • the device is likely to present variants.
  • the drive and guide assembly of the cover comprising the pin 13, the guides 16, 17 and the stops 18, is replaced by another assembly, illustrated by the Figure 4, and comprises a cover 10 whose edge has a peripheral groove 32 and stirrups 30 for holding and driving, screwed onto supports 31 forming part of the turn 5 and which penetrate into this peripheral groove 32.
  • the play of the stirrups 30 in the groove 32 is calculated to allow a suitable movement of the cover 10 under the action of the intermediate piece 19 as well as the rotation of the cover on itself.
  • the groove 32 is provided over the entire periphery of the cover.
  • This variant illustrated in FIG. 4, has the essential advantage of giving the cover a better grip thanks to a greater flexibility due to the peripheral groove, the operation and the arrangement between the cover and the seat remaining similar to the embodiment described with the aid of FIGS. 1 to 3.
  • an additional spring facilitates the retraction of the cover towards the turn when opening.
  • the invention provides a direct passage at the same time as a perfect and lasting seal which is particularly appreciable in the handling of corrosive and / or dangerous gases or liquids.
