Description
RESILIENT METALLIC SEALING MEMBER
The invention relates to a device for sealing the contact zone between a movable equipment part and a fixed equipment part.
BACKGROUND OF THE INVENTION
Devices of the type referred to serve for example to ensure a reliable and gas-tight seal between a movable shut-off element (for instance a hinge flap or a slide valve plate) of a hot gas pipe of large dimensions and a stationary seat.
In the known constructions of this type, the two flat long edge regions of the sealing element represent a straight-line extension of the curved zone and these two flat long edge regions are generally fixed by means of separate clamping arrangements. The principal disadvantages of these known constructions are that the overall height is considerable and installation is difficult.
SUMMARY OF THE INVENTION
The invention, therefore, seeks to provide a device in which the overall height of the sealing element is substantially reduced. In a further development of the invention installation and removal of the sealing element aresubstantially simplified.
According to the invention a sealing element has a hollow, deformable body having a domed top wall, two spaced apart side walls and a bottom wall.
Extensions projecting from the body are bent to overlie one another and extend longitudinally of the body. Such a construction of the sealing element makes it possible to achieve the spring rigidity of the sealing element which is desired for the particular application with a minimum overall height. At the same time the installation and removal of the sealing element is substantially simplified acco ng B~`

to the invention.
The invention in particular provides a sealing device for use in effecting a hot gas seal between two relatively movable parts, the device comprising at least one springy, integral, resilient metal member having a pair of 5 spaced apart side walls of uniform wall thickness joined at corresponding ends by a convexly domed top wall of corresponding wall thickness, at least one of the side walls being bent at its other end at an angle of substantially 90 and extending toward the other of the side walls to form a bottom wall of corresponding wall thickness underlying the top wall and spanning the space between the side walls 10 thereby forming with the top wall and the side walls a hollow, deformable body.
The bottom wall is free of the top wall and the other of the side walls and has an integral extension projecting beyond the body, the other of the side walls has at its other end an extension which extends beyond the body in overlying and confronting relation with the extension of the bottom wall and means secure the 15 extensions to one another. Each of the top, bottom and side walls is resiliently deformable from a non-deformed condition in response to the application of compressive force on the body in a direction to move the top wall toward the bottom wall, the movement of the top wall toward the bottom wall causing the side walls to bow outwardly of the body and the bottom wall to bow inwardly of 20 the body. The resilience of the walls enables them to return to their non-deformed condition in response to the removal of the compressive force.
Further advantageous constructions of the invention are explained in greater detail in connection with the description of preferred embodiments.

DETAILED DESCRIPTION
The sealing element 1 illustrated in FIG. 1 is formed by an elongated spring steel strip which is shown in cross-section and is shaped to form a hollow, deformable body 4 having two spaced side walls, a convexly domed top and a bottom wall. Extending from the body are two flat, overlying, parallel extensions 2 and 3. A bend 5 of substantially 90 is provided between the flat extension 2 and the adjacent side wall. A corresponding bend 6 is located between the other sidewall to form the bottom wall and the extension 3. The two extensions 2 and 3 areflat and extend beyond the body in prolongation of the bottom wall at right angles to the longitudinal extent thereof and towards the same side.
The two extensions 2 and 3 are firmly connected to one another at certain intervals (at right angles to the drawing plane of FIG. 1 ) by spot welds 7, 8 and these welded connections take up the spring tension of the curved zone 4.
Through holes 9, 10 are also provided at certain intervals in the extensions 2, 3 to receive connecting clamps.
B ;
FIG. 2 shows the sealing element 1 according to FIG. 1 in the installed state. The flat extensions 2, 3 are fixed between a stationary seat 11 and a clamping strip 12, the clamping strip 12 being connected to the stationary seat 1 1 by means of connecting elements 13.
A movable shut-off element 14, which can be formed for example by a hinged flap or a slide valve plate and is movable in the direction of the arrow 15 to apply compressive force on the sealing element, cooperates with the stationary seat 1 1.
In the closed position of the shut-off element 14, the sealing element 1 comes to rest with a part of its curved zone 4 on the shut-off element 14 and the top, bottom and side walls are thereby elastically deformed as illustrated by the contour 1' shown in broken lines in FIG. 2.
The installation and removal of the sealing element 1 is extremely simple and can readily be carried out by one person alone. In the installation of the prefabricated sealing element, the extensions 2 and 3 of which are firmly connected to one another, the clamping strip 12 is merely placed on it and the flat long edge regions 2, 3 are fixed by means of the connecting elements 13. Any replacement of the sealing element which may be necessary is equally simple.
In the embodiment according to FIG. 2 the two extensions 2, 3 of the sealing element 1 are arranged at right angles to the direction of movement (arrow 15) of the movable part of the equipment (shut-off element 14). This construction produces a particularly low installation height H of the sealing element.
In the embodiment according to FIG. 3 two sealing bodies I and la which can be fixed by means of the same clamping strip 12 are provided in mirror lE~
.
13~8214 symmetry. Such a construction is advantageous for example when a gaseous sealing medium, e.g. sealing air, is to be introduced into the space 16 between the two bodies I and la. The two bodies are joined by overlying extensions like the extensions 2 and 3.
In the embodiment according to FIG. 4 two sealing bodies Ib, Ic which are constructed in mirror symmetry are united in one integral double sealing element and have central extensions 17, 18 Iying between and joining the two curved zones 4b, 4c. The extensions 17, 18 overlie one another and are fixed by means of the clamping strip 12 and the connecting elements 13. The two extensions 17, 18 of this double sealing element are firmly connected to one another, preferably by spot welding, so that they can be jointly fixed in the ready-connected state by means of the clamping arrangement. In this embodiment the bottom wall of each body is arcuate, rather than flat.
FIG. 5 shows an embodiment in which the two extensions 2, 3 of the sealing element Id are arranged to extend in prolongation of one side wall of the body and parallel to the direction of movement (arrow 15) of the movable part ofthe equipment (shut-off element 14). Here too the two extensions 2 and 3 which are firmly connected to one another are jointly fixed by means of a clamping strip 12 and connecting elements 13. This construction is distinguished by a particularly small overall width B of the sealing element Id.
In the embodiment according to FIG. 6 the two sealing elements le and If are fixed on the movable shut-off element 14 by means of separate clamping strips 12e and 1 2f and connecting elements 1 3e and 1 3f respectively.
In the closed position of the movable shut-off element 14 the sealing B
elements le and If come to rest on the stationary seat llg, for example a collar of the pipe housing 19.
As in the embodiments described above, in the variant according to FIG. 6 the two extensions are also firmly connected to one another, preferably by 5 spot welding, so that they can be jointly fixed in the ready-connected state with the aid of the clamping arrangement.
FIG. 7 shows an embodiment in which (as in FIG. 4) sealing elements lg and Ih are united to form one integral double sealing element. As in the arrangement according to FIGS. 1 and 2, the two sealing elements each have two bends 59, 69 and 5h, 6h respectively by means of which the central extensions 1 7a, 1 8a are connected to the curved zones 49 and 4h respectively.
The region of the sealing elements lg, Ih located between the two bends 59, 69 and 5h, 6h respectively is supported with a part of its width on a support 20 or 21 which is movable in the direction of the arrows 22, 23. The 15 spring force of the sealing elements lg, Ih can be set within wide limits by moving these supports 20, 21. For example, a substantially reduced spring force, i.e. a weaker springiness of the sealing element, is produced if the support 20 is moved towards the right.
A similar means for alteration of the spring force is shown in FIG. 8.
20 The sealing element Id here corresponds to that of the embodiment according to FIG. 5. An angled clamping strip 12' serves for fixing of the extensions 2 and 3 and one arm of the clamping strip supports the region of the sealing element located between the bends 25 and 26 on only a part of its width. By alternating the length of this arm it is possible to bring the spring force of the sealing element B
to the desired value in a simple manner. 13 3 8 21~
FIG. 9 shows how the contact points at the corners can be constructed in the case of a sealing device composed for a plurality of sealing elements. Of the two sealing elements I and ll" shown in FIG. 9, the sealing element 1" butts against the other sealing element I at an angle of approximately 90 and the latter sealing element 1 projects somewhat beyond the contact point.The sealing element 1" has at its end facing the other sealing element 1 a thrust piece Ix which overlaps the main part Iy of the sealing element 1"
(overlap 26) and is freely movable in the axial direction of the sealing element 1"
for the purpose of adjustment. In this way, during installation of the sealing device the thrust piece Ix can be pushed forwards until it rests on the sealing element 1 and can be fixed in this position by the appertaining clamping strip 12.
The sealing elements I and 1" butt loosely, that is to say unconnected, against one another. Equally a loose overlap between the main part Iy and the thrust piece Ix of the sealing element 1" is sufficient. The thrust piece Ix is cut out at its end facing the sealing element I to correspond to the contour of the sealing element 1, which leads to a reliable seal in the region of the curved zone which in the closed position of the movable part of the equipment rests resiliently on anopposing surface.
In pipes which are subjected to hot gas there is a danger that condensation and resulting pitting will occur on the cold side of the sealing element facing the hot gas. In order to exclude this danger, it is possible within the scope of the invention for the sealing element facing the hot gas to be heated, which can be achieved for example by means of a heating spiral or a hot air stream. If the B
133821~
critical zones of the sealing element are heated in this way to above the dew point temperature, instances of condensation and resulting damage are avoided.
The elastic deformation of all outer surfaces of the periphery illustrated in FIG. 2 by broken lines is particularly characteristic of the sealing 5 element according to the invention. In this way a particularly large sprung peripheral length is produced which makes it possible to achieve the desired springiness of the sealing element with a substantially reduced overall height H.
