    (37693) II
    The invention relates to a device for mounting an annular flange seal comprising a replaceable in an annular groove of the screwed together annular flanges, ferromagnetic sealing ring.
    For sealing ring flange connections used in the course of pipelines, metallic sealing rings are used which engage in annular grooves of the annular flanges which can be screwed together and, when the flange screws are tightened, are pressed sealingly into the annular grooves under elastic and plastic deformation. The sealing rings are often made of a soft iron material for this purpose. A disadvantage of the assembly or when replacing the annular flange seals, that the sealing ring must be inserted into the mounting gap between the annular flanges to be connected and held in a concentric with the annular grooves position when tightening the flange the engagement of the sealing ring in the axially opposite each other To ensure ring grooves of the ring flanges. This montagegerechte holder in the gap between the annular flanges is particularly difficult if the axis of the pipe runs horizontally and is expected to larger nominal diameters of the pipes. In this context, it should be considered that the gap width of the mounting gap between the annular flanges to be connected is generally only slightly larger than the height of the sealing ring.
    The invention is therefore based on the object to provide a device by means of which the sealing ring can be held in a simple manner in a predetermined mounting position between the annular flanges to properly by a corresponding • • 2 tightening the flange the sealing ring in him receiving To be able to press in annular grooves.
    Starting from an annular flange seal of the type described above, the invention solves the problem by an insertable between the annular flanges grip web, at its one end a magnetic shoe with a matched to the outer diameter of the sealing ring, extending over only a portion of the height of the sealing ring recording having for the sealing ring.
    The invention makes use of the fact that conventional sealing rings for the addressed annular flange seals made of a ferromagnetic material, so that a holder of the sealing rings is possible via magnetic forces. The holder of the sealing ring at the end of an insertable into the mounting gap between two annular flanges handle web is structurally achieved in that the intended for the ring holder, magnetic shoe has a matched to the outer diameter of the sealing ring receptacle, which engages positively in the circumferential direction of the sealing ring and thereby ensures that the ring plane coincides at least substantially with the grip level. Since the recording formed by the magnetic shoe for the sealing ring extends only over part of the height of the sealing ring, the sealing ring can be held by means of the handle bar during assembly until the engagement of the sealing ring in the annular grooves of the annular flanges in the mounting position. After that, a separate holder of the sealing ring is no longer necessary.
    Particularly advantageous mounting conditions arise when the recording of the shoe for the sealing ring has a circumferentially extending row of radially aligned permanent magnets, which brings a favorable for the ring holder course of the magnetic lines with it. The permanent magnets should thereby determine with their free poles at least approximately a cylindrical surface for engagement on the outer circumference of the sealing ring. If the pole faces of the permanent magnets are provided with a corresponding cylindrical surface, this results in particularly advantageous investment conditions. In most cases, however, it is sufficient to use permanent magnets with flat pole faces which are tangential to the cylindrical surface of the sealing ring.
    So that the grip bar can not affect the magnetic flux of the permanent magnets, it is recommended that the handle bar be made of a non-ferromagnetic material.
    In the drawing, the subject invention is shown, for example. Show it
    1 shows an annular flange seal in a schematic axial section, and FIG. 2 shows a device according to the invention for mounting such a ring flange seal in a simplified side view.
    In Fig. 1, a conventional annular flange seal is shown. The provided in the course of a pipe flange connection has two to be screwed together annular flanges 1, which receive between them a sealing ring 2, which engages in a respective annular groove 3 of the annular flanges 1. With the help of distributed over the circumference of the annular flanges 1 flange 4, the usually made of a soft iron material sealing ring 2 can be pressed sealingly under an elastic and plastic deformation in the annular grooves 3.
    In order to mount the sealing ring 2, the annular flanges 1 are positioned at a mutual axial distance, which is generally only slightly larger than the height of the sealing ring 2. This means that the sealing ring 2 is inserted into the comparatively narrow mounting gap between the annular flanges 1 and concentric with this in the mounting gap to keep the annular grooves 3 until the sealing ring 2 engages sufficiently deep for a self-mounting in the annular grooves 3. For this purpose, a grip web 5 is provided according to the invention, which has at its one end a magnetic shoe 6 with a receptacle 7 for the ferromagnetic sealing ring 2, as shown in FIG. 2 can be removed. This receptacle 7 is adapted to the outer diameter of the sealing ring 2 and is advantageously formed by a circumferentially extending row of radially aligned permanent magnets 8. From Fig. 1 it is seen that the handle bar 5 with the shoe 6 has a thickness which extends over only a portion of the height of the sealing ring 2, so that the sealing ring 2 are held on the handle bar 5 even when tightening the flange 4 screws right can.
    Since the permanent magnets 8 abut the outer circumference of the sealing ring 2, the sealing ring 2 can be advantageously held in a plane with the handle bar 5 and introduced into the mounting gap between the annular flanges 1 in order to produce the annular flange seal with the tightening of the flange screws 4 used. The handle bar 5 can then be deducted from the sealing ring 2 and pulled out of the remaining gap between the annular flanges 1. To be able to hold in particular sufficiently accurate sealing rings 2 with a larger diameter in a mounting position, two or more gripping ridges 5 can be used distributed over the circumference of the sealing ring 2.
