Definitions
- the invention relates to a closure device for the vacuum-tight closure of an opening in a wall, with a valve plate which can be adjusted between a closed position in which the valve plate seals the opening and an open position in which the valve plate opens the opening and which is connected via a connecting device to a valve rod of the closure device having a longitudinal axis, the connecting device having a joint head, of which at least sections of the outer surface are spherical in shape and which is arranged in a receiving space of a joint body.
- US 2011/0108750 A1 discloses a connecting device between a valve rod and a valve plate, which has a twistable cross member. A certain pivoting of the valve plate relative to the valve rod is made possible by torsion of the cross member.
- a closure device of the type mentioned is known from prior use.
- a shaft (which can be viewed as a "valve rod") which can be rotated by a drive motor is connected to the valve plate via a pendulum arm which extends at right angles to the longitudinal axis of the shaft and forms a ball joint at the end remote from the shaft, to which the valve plate is attached
- the pendulum arm has a pot-shaped recess in which a joint head is arranged, of which a section of the outer surface is spherical in shape.
- joint socket parts placed on the joint head from opposite sides, each of which has a concave joint surface in the form of a section of a spherical inner surface and which are also arranged in the cup-shaped recess of the pendulum arm.
- the joint socket parts are attached to the Joint head pressed.
- a through-hole through the joint head has a screw passing through it, which also passes through an opening in the spring plate and with which the valve plate is screwed to the joint head in the area of the opening in the spring plate.
- this valve plate holder is only suitable for valve plates with a circular outer diameter.
- Ball joints are used in different fields of technology, for example also for the articulated connection between the wheel carrier and the wishbone in axle arrangements of motor vehicles.
- a special ball joint of this type is disclosed in DE 10 2015 213 298 A1.
- the articulated head has pins protruding on both sides, which protrude into a respectively assigned groove, the grooves being arranged in side walls of a receiving space of a housing-like joint body. With this design, steering torques can be supported on the ball joint.
- the object of the invention is to provide an advantageous closure device of the type mentioned at the outset, which has a wide range of uses. According to the invention, this is achieved by a closure device having the features of claim 1 .
- At least one protruding pin is provided to block a rotation of the joint head relative to the joint body about the longitudinal axis of the valve rod, which is arranged on the joint head or on the joint body and protrudes into an associated groove which is arranged on the other of these two parts . That groove extends in a central position of the connecting device, in which the valve plate is aligned at right angles to the longitudinal axis of the valve rod, in a plane parallel to the longitudinal axis of the valve rod. It is preferred here that a protruding pin is arranged on opposite sides of the joint head or joint body and engages in a respectively assigned groove in the other of these two parts, which extends in the middle position of the connecting device in the said plane.
- the closure device according to the invention is also suitable for designing the valve plate with a shape that deviates from the circular shape, in particular an at least essentially rectangular shape (i.e., for example, a rectangular shape with rounded corners ) suitable .
- the rotational position of the valve plate relative to the longitudinal axis of the valve rod and thus also relative to the axis of the opening that can be closed by the valve plate is thus fixed, while an adjustment of the plane in which the valve plate lies to the plane in which the opening lies is possible is in order to achieve a uniform pressure on the valve seat in the closed position of the valve plate and thus a circumferentially uniform compression of the sealing ring.
- the closure device according to the invention can be a vacuum valve which has a valve housing, one wall of which has the opening which can be closed by the valve plate. Such a valve housing then has a further opening in order to have a through-channel through the valve housing when the valve plate is in the open position to train .
- the closure device according to the invention can also be used to seal an opening in a wall of a vacuum chamber. In this embodiment, the wall with the opening that can be closed by the valve plate does not form part of the closure device according to the invention.
- valve plate is connected to the articulated body and the valve rod is connected to the articulated head, preferably by means of a connecting screw passing through a central through bore through the articulated head and screwed into a threaded bore at the front end of the valve rod.
- a threaded bolt molded onto the joint head would also be conceivable and possible.
- the joint body is preferably designed as a housing, with a cup part that has a cup-shaped depression that accommodates the joint head, and a cover part that covers the depression and is sealed off from the cup part by an intermediate seal.
- the valve rod advantageously passes through an opening in the cover part of the joint body, with an annular gap being present between the valve rod and the edge of the opening in the cover part in the middle position of the connecting device. Particles that are formed during the movement of the joint head relative to the joint body can thus advantageously be retained at least largely in the housing-shaped joint body. It is particularly preferred here if a sealing ring is arranged on the joint head, which rests against the inside of the cover part in a region surrounding the opening of the cover part.
- a first and a second joint socket part are arranged in the joint body. These each have a concave joint surface in the form of a section of a spherical inner surface, with the concave joint surfaces of the joint socket parts each interacting with an associated convex joint surface of the joint head.
- These convex joint surfaces of the joint head are formed by sections of the outer surface of the joint head which are in the form of sections of a spherical surface.
- first and second joint socket parts are pressed against the joint head by at least one spring-elastic element.
- the joint head can be held in its respective position in relation to the joint socket parts and thus in relation to the joint body by friction.
- the holding force holding the joint head is preferably so great that the torque exerted by the valve plate due to its weight can be absorbed in every possible spatial arrangement of the closure device without the joint head being displaced relative to the joint body.
- a spring plate can be provided as a spring-elastic element for pressing the joint socket parts onto the joint head. which is adjacent to the cap portion of the joint body and which is pressed against the socket portion located on that side of the condyle.
- the other socket portion may rest on the bottom surface of the cup-shaped depression in the cup portion of the joint body.
- This spring plate can be fastened to the cup part of the joint body, for example by screws.
- the spring plate In the area of the opening of the cover part, the spring plate has a corresponding opening which is at least large enough so that it does not protrude into the area of the opening of the cover part (seen in the axial viewing direction of the opening in the cover part).

- FIG. 11 and 12 exploded views of the connecting device from different perspectives.
- FIGS. 1 to 16 An exemplary embodiment of a closure device according to the invention is described below with reference to FIGS. 1 to 16 explained .
- the closure device has a valve plate 1 which can be adjusted between an open position (FIG. 1) and a closed position (FIG. 2). In the off position of the valve plate, an opening 2 in a wall 3 is released, in the closed position the opening 2 is closed in a vacuum-tight manner by the valve plate 1 .
- a vacuum-tight closure means a leak rate Q of at least less than 10 ⁇ 4 mbar 1/s.
- valve plate 1 is carried by a valve rod 4 having a longitudinal axis 26 . In the exemplary embodiment from the adjustment of the valve plate 1 takes place between the
- valve plate could also be adjusted between the open and closed positions in the manner of an L or J movement, for example by axial displacement and subsequent tilting of the valve rod or subsequent displacement of the valve rod at right angles to it Longitudinal axis, as this is known.
- a drive 5 is used, which in the exemplary embodiment is formed by a pneumatic piston-cylinder unit.
- the valve rod 4 is connected to the piston rod of this piston-cylinder unit or formed in one piece with it.
- a sealing ring 8 made of an elastomeric material serves to seal between the valve plate 1 and the wall 3 in the closed state of the closure device. In the exemplary embodiment, this is attached to the valve plate 1, as is preferred.
- the opening 2 in the wall 3 is surrounded by a sealing surface which forms the sealing seat against which the sealing ring 8 bears when the valve plate 1 is in the closed position.
- a reverse arrangement (sealing ring on the wall 3 , sealing surface on the valve plate 1 ) is also fundamentally conceivable and possible.
- the wall 3 can be part of a valve housing, which is shown in FIGS. 1 to 4 each only a part is shown. The remaining part of the valve housing is shown in FIG. 5 indicated by dashed lines.
- This valve housing thus has an interior space in which the valve plate 1 is arranged.
- a valve housing second in Fig . 5 also indicated opening 9, for example opposite the opening 2, in order to form a through-channel through the valve housing in the open position of the valve plate 1.
- the closure device thus also includes the valve housing with the wall 3 with the opening 2 and forms a vacuum valve.
- the valve housing has a further opening 11 through which the valve rod 4 is guided out of the interior of the valve housing.
- This opening 11 is closed in a vacuum-tight manner by a connection piece 10 to which the drive 5 is attached, the valve rod 4 passing through a through-channel through the connection piece 10 and being guided axially by it.
- An annular seal 12 serves to seal between the valve housing and the connecting piece 10 .
- a bellows 6 is used to seal the valve rod 4 from the through-channel through the connecting piece 10 .
- This is connected at one end via an annular connecting piece 13 to the connecting piece 10 in a vacuum-tight manner, with a sealing ring (not visible in the figures) being arranged between the connecting piece 10 and the connecting piece 13 .
- the bellows 6 is connected to the valve rod 4 in a vacuum-tight manner.
- a sliding seal with at least one sealing ring could also be provided for sealing.
- the closure device as shown in FIGS. 1 to 4, ie as shown in FIG. 5 without the dashed lines may also be attached to the outside of a wall of a vacuum chamber, with the opening 2 being aligned with an opening in that wall of the vacuum chamber and the Wall 3 is sealed in the area surrounding the opening 2 compared to the wall of the vacuum chamber.
- the closure device could also be referred to as a door.
- the wall 3 having the opening 2 could also be part of a vacuum chamber.
- This vacuum chamber thus has another opening, corresponding to the opening 11 shown in the figures, through which the valve rod 4 is led out of the interior of the vacuum chamber and which is closed by the connection piece 10, the drive 5 in turn being attached to the connection piece and the Valve rod extends through a passageway in the fitting.
- the valve rod can in turn be guided into the vacuum region of the vacuum chamber in a sealed manner by means of a bellows (or by means of a sliding seal).
- the wall 3 having the opening 2 is therefore not part of the closure device according to the invention.
- the wall 3 having the opening 2 could also be arranged on the inside of a wall of a vacuum chamber, with the opening 2 of the wall 3 being aligned with the opening in the wall of the vacuum chamber.
- a closure device can also be referred to as an “insert”.
- the valve rod 4 would preferably be guided out of the vacuum chamber in a sealed manner, so that the drive 5 is located outside the vacuum region of the vacuum chamber.
- the valve plate 1 is substantially rectangular
- Circumferential contour formed means here that the valve plate is rectangular with rounded corners.
- the opening 2 has a corresponding contour and is surrounded by the sealing surface 14 against which the sealing ring 8 is pressed when the valve plate 1 is in the closed position.
- a connecting device 15 serves to connect the valve rod 4 to the valve plate 1 .
- This has a joint head 16 which is arranged in the inner receiving space 18 of a joint body 17 .
- the joint head 16 is rigidly connected to the valve rod 4 and the joint body 17 is rigidly connected to the valve plate 1, as is preferred.
- the joint body 17 comprises a pot part 17a, which has a pot-shaped depression, and a cover part 17b, which closes the pot part.
- the inner receiving space 18 is thus formed at least essentially by the pot-shaped recess of the cover part 17b.
- the cover part 17b is sealed off from the cup part 17a by means of an annular seal 21 arranged between the cup part 17a and the cover part 17b.
- the cover part 17b is connected to the pot part 17a via screws 22 .
- the valve rod 4 is connected to the joint head 16 by means of a connecting screw 23 which penetrates a central through hole 24 through the joint head 16 and is screwed into a threaded hole 25 on the front end of the valve rod 4 .
- the valve rod in this case has a connecting portion 4a with an at least substantially square cross section and the joint head 16 has a recess 16a with a corresponding outer contour, in which the connecting portion 4a of the Valve rod 4 protrudes.
- the valve rod 4 is thus secured against rotation relative to the joint head with respect to a rotation of the joint head 16 relative to the valve rod 4 about the longitudinal axis 26 of the valve rod 4 .
- a square contour another polygonal contour or another contour deviating from the circular shape, for example an oval contour or a star-shaped contour, could also be provided.
- an anti-twist device could also be designed in a different way.
- the cover part 17b has a window opening 27 through which the valve rod 4 protrudes in the area of an end section.
- a central position of the connecting device in which the valve plate 1 is aligned at right angles to the longitudinal axis 26 of the valve rod 4 (i.e. the central plane of the valve plate 1 is at right angles to the longitudinal axis 26), there is between the valve rod 4 and the edge of the window opening 27 in the Cover part 17b before an annular gap s, d. H . around the entire circumference of the valve rod 4 it is spaced from the edge of the window opening 27, preferably evenly.
- this enables (limited) pivoting of the valve plate 1 about any axis that is at right angles to the longitudinal axis 26 of the valve rod 4, as will be explained in more detail below.
- a connection section 29 arranged on the rear side of the valve plate 1 has a depression 30 .
- the pot part 17a has a protruding portion which can be inserted into the recess 30 .
- the recess 30 of the connecting portion 29 has opposite lateral extensions.
- Connecting pins 32 protrude into these, which are screwed into threaded holes in the pot part 17a on the outside in the area of the step.
- the shank of each connecting pin 32 has a constriction 32a.
- Fastening bolts 33 protrude into these constrictions and are inserted into bores 34 of the connecting section 29 extending transversely to the connecting pins 32 , the bores 34 opening into the areas of the lateral expansions of the recess 30 .
- the connecting section 29 is part of a transverse beam which is connected to the plate part of the valve plate on both sides of the connecting section 29 and is spaced apart from the plate part of the valve plate in the area in between. If the wall 3 having the opening 2 has a certain curvature (related to the direction of the longitudinal extension of the valve plate), the valve plate 1 can thereby adapt to this curvature within a certain range. A uniform compression of the sealing ring 8 is thereby additionally supported.
- a first and a second joint socket part 35 , 36 are arranged in the receiving space 18 of the joint body 17 .
- the socket parts 35, 36 each have a concave articulation surface 35a, 36a.
- This concave joint surface 35a, 36a each has the shape of a section of a spherical inner surface.
- the concave joint surfaces 35a, 36a of the joint socket parts 35, 36 are placed on the joint head 16 from opposite sides and interact with respectively associated convex joint surfaces 16b, 16c of the joint head 16 together .
- the convex joint surfaces 16b, 16c are each in the form of a section of a spherical surface and each represent a section of the outer surface of the joint head 16.
- the concave joint surfaces 35a, 36a each have the shape of a spherical inner surface of a hollow spherical disk.
- the joint socket parts 35 , 36 thus have at least essentially the shape of hollow spherical disks.
- the center planes of the joint socket parts 35 , 36 are at right angles to the longitudinal axis 26 of the valve rod 4 . In the middle position, the center planes of the spherical disc-shaped sections of the joint head 16 forming the convex joint surfaces 16b, 16c also lie in planes which are at right angles to the longitudinal axis 26.
- the joint socket parts 35 , 36 are pressed against the joint head 16 by a resilient element 37 .
- this resilient element 37 is formed by a spring washer which is arranged adjacent to the cover part 17b and has an opening 37a in the region of the window opening 27 of the cover part.
- the resilient element 37 is screwed onto the cup part 17a by means of screws 38 . In the area adjoining the opening 37a, it has radial incisions and the segments severed from the incisions are bent up.
- the spring-elastic element 37 rests on the second joint socket part 36 and presses it against the joint head 16, whereby the joint head 16 is pressed against the first joint socket part 35, which rests on a floor surface at the bottom of the cup-shaped depression in the cup part 17a.
- the joint head is thus held in the current position by frictional engagement.
- This frictional connection is so strong that the weight of the valve plate 1 can also be absorbed without the position of the joint head 16 changing, regardless of the spatial position of the closure device.
- the opening 37a of the resilient element 37 is larger than the window opening 27 of the cover part 17b.
- a sealing ring 19 arranged on the joint head 16 in an area surrounding the recess 16a can pass through the opening 37a of the spring-elastic element 37 and be pressed against the inside of the cover part 17b in an area surrounding the window opening 27 .
- the sealing ring 19 could also be attached to the inside of the cover part 17b and pressed through the opening 37a onto the surface of the joint head 16, specifically in an area surrounding the depression 16a.
- the joint head 16 has pins protruding on opposite sides.
- the pins 16d each protrude in a direction that is at right angles to the longitudinal axis 26, the pins 16d being coaxial with one another.
- a respective pin 16d protrudes into a respective assigned groove 17c in the pot part 17a of the joint body 17 .
- a respective one of the grooves 17c is formed in a wall delimiting the cup-shaped depression, ie. H . expands this pot-shaped recess of the pot part 17a.
- the grooves 17c extend in a plane 20 (shown in FIG. 11) which lies parallel to the longitudinal axis 26 of the valve rod 4 in the central position of the connecting device.
- the grooves 17c run in the middle position of the connecting device in a straight line parallel to the longitudinal axis 26 of the valve rod 4 .
- the inner wall delimiting the cup-shaped depression of the cup part 17a could also be curved in relation to the direction parallel to the valve rod 16, so that the grooves 17c would extend in a correspondingly curved manner.
- the pins 16d emanate from an annular region of the outer surface of the joint head 16 lying between the joint surfaces 16b, 16c of the joint head 16 . In particular, they are located on the equator of the joint head 16 , the equator of the joint head 16 lying in an equatorial plane which is at right angles to the longitudinal axis 26 of the valve rod 4 and which penetrates the joint head 16 in the middle.
- the joint head 16 is blocked by the pins interacting with the grooves with respect to rotation relative to the joint body 17 about the longitudinal axis 26 of the valve rod 4 .
- the joint head 16 can be tilted about any axis that is at right angles to the longitudinal axis 26 of the valve rod 4 (until the annular gap s is used up).
- the connecting device thus forms a ball and socket joint which is locked with respect to rotation about an axis perpendicular to the equatorial plane of the joint head 16, ie about the longitudinal axis 26 of the valve rod 4 connected to the joint head.
- the joint formed by the connecting device can also be used as a nut joint, which with respect to a rotation about a direction perpendicular to the equatorial plane of the Rod head 16 standing Axis , ie about the longitudinal axis 26 of the valve rod 4 connected to the joint head , can be designated .
