Definitions
- Sealing arrangement for a shut-off device such as a slide, flap or the like
- the invention relates to a sealing member for a shut-off member which can be moved from a closed position to an open position and vice versa, such as a slide, flap or the like, consisting of a sealing ring which, in the closed position of the shut-off member, can be moved with its sealing surface into a sealing position.
- Such a sealing arrangement is generally known.
- z. B. refer to DE 34 01 955 AI.
- the known seal arrangement is an inflatable hose seal, consisting of a hose body made of an elastic, high-density material, and a sealing ring which can be inserted into a groove and exchangeable if necessary.
- the hose body consists of an elastic and fluid-tight material, e.g. B. a fluorine elastomer, while the sealing ring made of a particularly friction-resistant material, for. B. made of silicone.
- the known sealing arrangement is used in particular for sealing a rotary lid for a nuclear reactor tank.
- the known sealing arrangement is not suitable for sealing shut-off elements for media of high temperature and aggressive composition.
- the present invention has for its object to provide a sealing arrangement of the type mentioned, the application of a sufficiently high with little design effort and using small forces Sealing force allowed even when the shut-off element is under the influence of an operating medium with high pressure and high temperature.
- the sealing ring which preferably consists of highly wear-resistant sealing material, is embedded in a circumferential groove-like recess in a multilayer flexible elastic membrane and its sealing surface can be moved in the sealing position under the action of a pressure medium acting on the membrane.
- the essence of the invention lies above all in the multilayer structure of the membrane mentioned. Due to the multilayer or multilayer structure of the membrane, the deformation forces of the membrane can be reduced to a minimum, with the consequence of a correspondingly increased efficiency of the pressure transformation from the pressure medium acting on the membrane to the sealing ring.
- the membrane consists of at least two, in particular four or more high-temperature resistant
- the sealing arrangement designed in this way is therefore also suitable for shut-off elements which are exposed to high temperatures. Furthermore, the sealing arrangement according to the invention allows the sealing force to be reduced to a minimum with the
- shut-off element when actuated or moved from a closed position into an open position and vice versa.
- the sealing arrangement according to the invention is suitable for all types of slides or flaps. It can be used both on the movable part, ie shut-off element, and on the immovable part, namely housing or the like of the shut-off device. arrange direction. Accordingly, the membrane along its inner and outer edge of the arrangement on the shut-off element is fluid-tightly connected, in particular welded, to the housing or, if arranged on a housing assigned to the shut-off element, in such a way that between the membrane on the one hand and the shut-off element or housing on the other hand, a pressure medium space is limited, which is connected to a pressure medium reservoir via a pressure medium line.
- the size of the sealing surface of the sealing ring is a function of the ratio of the maximum pressure that can be built up in the pressure medium space to the required sealing pressure and the wear resistance of the material of the sealing ring.
- the pressure medium acting on the membrane can be gaseous or liquid.
- Fig. 1 shows a part of a first embodiment of a sealing arrangement according to the invention in
- FIG. 2 shows a part of a second embodiment of a sealing arrangement according to the invention in radial section and in association with a shut-off element, namely slide, which can be moved from a closed position into an open position and vice versa.
- a shut-off element namely slide
- the sealing arrangement assigned to the slide plate 3 consists of a sealing ring 2 made of highly wear-resistant sealing material, which extends around the axis of rotation 4.
- the side of the sealing ring 2 facing the shut-off plate 3 is flattened to form a circumferential one
- the sealing ring 2 is embedded in a circumferential groove-like recess 18 of a multilayer or multilayer (5 layers), flexible membrane 1 and under the action of a pressure medium acting on the membrane 1 with its sealing surface 6 in the sealing position, ie. H. against the
- a sealing arrangement of the type shown is preferably assigned to both sides of the shut-off plate 3, so that a sealing of the pipeline is ensured not only on the side of lower pressure, but also on the side of higher pressure of the shut-off plate 3.
- the membrane 1 is fluid-tightly connected to the housing 11 along its inner and outer edge, namely welded (ring weld seams 7), in such a way that between the membrane 1 on the one hand and the housing 11 on the other hand a circumferential pressure medium space 14 , 15 is limited, which is in fluid communication with a pressure medium reservoir 9 via a pressure medium line 8.
- the membrane 1 is reinforced by additional, circumferential strips of material 19, 20 (along the inner edge of the membrane) or 21, 22 (along the outer edge of the membrane) by the increase occurring in these areas To be able to compensate for bending moments.
- the cross section of the membrane 1 is approximately U-shaped, the two legs each being bent outwards so that they extend approximately parallel to the sealing surface 6 of the sealing ring 2.
- the ring facing the membrane is correspondingly Surface of the housing 11 for flush recessed reception of the membrane 1 together with the sealing ring 2, wherein in the relieved state of the membrane between this and the mentioned annular surface 23, a circumferential pressure medium space in the area of the sole of the circumferential recess 18 as well as in the bending area of the both membrane legs.
- These pressure medium spaces are identified by reference numerals 15 and 14, respectively.
- Fig. 1 also reveals that the circumferential recess 18 of the membrane 1 in a corresponding circumferential recess
- the sealing ring 2 can be pressed so strongly into the housing recess 24 that the membrane 1 lies completely against the housing ring surface 23 over its entire length and width.
- the volume of the pressure medium spaces 14, 15 is reduced to almost zero. It is advantageous that despite the high forces acting on the sealing ring 2, the membrane 1 is no longer subjected to any further deformation. The ring weld seams 7 are then no longer stressed.
- the service life of the described sealing arrangement is correspondingly high.
- the pressure transmission membrane 1 is shown in the unloaded state. In this state, the distance 13 between the sealing surface 6 of the sealing ring 2 and the associated surface of the shut-off element 3 is approximately equal to the maximum distance 12 between the membrane 1 and the deepest point of the
- the pressure medium container 9 is designed as an expansion container or vessel, preferably in a bellows-like manner.
- the pressure medium pressure is preferably generated purely mechanically, namely z. B. by a weight 10.
- a weight a spring can also be provided.
- the weight 10 mentioned in the first place has the advantage that the pressure medium pressure remains essentially constant, irrespective of the operating temperature due to the possibility of expansion of the pressure medium container 9.
- a liquid medium preferably serves as the pressure medium.
- the described sealing arrangement is arranged on the pressure side of a shut-off element, leakages can also be reliably avoided there.
- the sealing ring 2 is pressed depending on the operating medium pressure.
- the described sealing arrangement can therefore be adjusted depending on external conditions.
- the groove-like recess 18 of the multilayer membrane 1 each has a circumferential shaft 26 (radially inside) and 27 (radially outside) with an approximately S-shaped cross section, such that the inner and outer edges of the membrane 1 each extend approximately parallel to the direction of movement 25 of the sealing ring 2 .
- edge stresses of the membrane can be reduced to a minimum without the flexibility of the membrane being impaired.
- the annular surface 23 of the housing 11 facing the membrane 1 is of course also formed. In the radial section, this has a contour that corresponds to that of the membrane 1. In turn, the same effects and advantages can be achieved as are described with reference to the exemplary embodiment according to FIG. 1.
- the individual strips of material from which the membrane 1 is made are made of metal which is resistant to high temperatures and which is sufficiently elastically deformable even at high temperatures. In every state of the membrane, the strips of material lie close together over their entire length and width. As a result, the efficiency of the pressure transformation mentioned at the outset is additionally promoted.
- the above-mentioned load 10, which acts on the pressure medium reservoir 9, is coupled to the drive and dead stroke of the shut-off element 3 in such a way that partial or complete relief of the pressure medium reservoir 9 takes place when the same is actuated. This ensures that the shut-off element 3 moves smoothly when it moves from the closed position into the open position and vice versa.
- FIG. 2 also shows a minimum distance 5 between the membrane 1 and the shut-off device 3, which must be maintained in the unloaded state, ie in the moving position of the shut-off device 3, taking into account the maximum wear on the sealing surface 6 by to avoid direct contact between membrane 1 and shut-off device 3.
- pressure medium spaces 14 formed on both sides of the sealing ring 2 are originally free of pressure medium. Pressure medium only enters these spaces 14 when pressure medium passes the circumferential contact edges 16. In addition, excess pressure medium escapes again from the circumferential pressure medium spaces 14 into the circumferential pressure medium space 15, which is fluidly connected to the pressure medium line 8.
