    摘要： © Bei einer Vorrichtung zum Schleifen und Läppen von Flächen in Schiebern und dergl. in situ ist eine an dem Gehäuse des Shiebers oder dergl. befestigbare Halterung vorgesehen, die eine Führung (13) aufweist, längs der ein Joch (15) verschiebbar ist. Dieses Joch (15) ist mit einem den Antrieb (6) mit der Werkzeugplatte (4) verbindenden Tragelement (5) lösbar verbunden. An dem Joch (15) greift eine reversierende angetriebene Hubvorrichtung (17, 18; 29, 30) an.

    摘要： The apparatus, for re-machining safety valves in situ on high pressure/high temperature plant and pipework, comprises a first gearbox and a second gearbox. The first gearbox has a first centre of rotation associated therewith and is configured to receive a driving torque. The second gearbox has a second centre of rotation associated therewith, is coupled to and is configured to be driven by the first gearbox. Coupling means is provided for transferring the drive torque from the first gearbox to the second gearbox. The coupling means is configured to define the location of the second centre of rotation relative to the first centre of rotation. A removable accessory assembly is provided and is coupled to the second gearbox, for carrying out a cutting, grinding or lapping operation to recondition a surface of a safety valve.

    摘要： The invention relates to a method for machining a sealing seat (24a, b), arranged at the end (26) of a connection pipe (8a, b), of a shut-off valve (6) fitted in a power generating or industrial plant (2), which method comprises the following steps: a) an upper valve part (16) and the internal housing fittings (32) are removed from the housing (10) of the shut-off valve (6), whereby a housing opening (14) is exposed, b) a clamping device (40), having a counter-bearing (56), is introduced through the housing opening (14) into the or a further connection pipe (8a, b) and fastened to the inner wall (50) thereof, c) a machine tool (58), having a bearing (64), is introduced into the housing (10) through the housing opening (14) and mounted with its bearing (64) on the counter-bearing (56), d) a machining step (B1-4) is carried out with the machine tool (58) on the sealing seat (24a, b), e) the machine tool (58) is detached from the counter-bearing (56) and removed through the housing opening (14), f) if need be, steps c) to e) are repeated with another or the same machine tool (58), g) the clamping device (40) is detached from the connection pipe (8a, b) and removed through the housing opening (14), and h) the upper valve part (16) and the internal fittings (32) are attached to the housing (10). A device for machining a sealing seat (24a, b), arranged at the end (26) of a connection pipe (8a, b), of a shut-off valve (6) fitted in a power-generating or industrial plant (2) comprises a clamping device (40), which can be introduced through a housing opening (14) of the shut-off valve (6) into the or a further connection pipe (8a, b) and includes a counter-bearing (56) and a fastening element (47) interacting with the inner wall (50) of the connection pipe (8a, b), and at least one machine tool (58), which can be introduced through the housing opening (14) into the housing, for carrying out a machining step (B1-4) on the sealing seat (24a, b), wherein the machine tool (58) has a bearing (64), which can be mounted in the counter-bearing (56).
