    摘要: The invention relates to a bellows to seal a valve rod passage in a lifting valve, specifically formed as an expansion bellows or corrugated tube, which ensures a reliable, hygienically proper and durable static sealing of the connecting flange of a closing-member unit in the box of the lifting valve under the occurring forces at an adequately long service life. This is achieved by the fact that the connecting flange (40) of the closing-member unit (4), in the region where it is connected to the bellows (4b), has a fastening component (4f) indirectly supported on the box side to absorb, in a way free from bending moments to a very large extent, the forces resulting from the valve-lift induced deformation of the bellows (4b) and/or the respective pressure in the box (1a) and is reduced, in the area of its conical sealing surface (4h), to a minimal wall thickness meeting the strength-related requirements, in the form of a diaphragm-shaped sealing element (4l), and that the diaphragm-shaped sealing element (4l), on its side facing away from the conical scaling surface (4h) has at least one biased elastic thrust ring (5) which presses the sealing surface (4h) onto the complementary annular seating surface (1k).

    摘要: The invention concerns a cleanable scraper station which is designed as a dispatch/receive station (1;1*) and through which the product or cleaning agent flows. The aim of the invention is to improve the cleanability of the scraper station compared with prior art devices, as measured by increased throughput, and in particular to ensure through cleaning of the entire scraper surface. This is achieved by virtue of the fact that the scraper (9) is positioned with play in all directions when in the through-flow position (II,II*) by means of a controllable second stop (6a;6a*) acting in conjunction with a displaceable first stop (5a,5a*) or by means of the controllable second stop (6a;6a*) acting in conjunction with a coupling cage (50;50*) connected to the displaceable first stop (5a;5a*) and in which the scraper (9) is positively locked, or only by means of the coupling cage (50;50*) connected to the displaceable first stop (5a;5*) and in which the scraper (9) is positively locked.

    摘要: The invention relates to a device for the drive system for double seat valves comprising two individually movable closure members which, in addition to the open position, can each be individually moved into a partial open position. The object of the invention is to construct a device which is easy to assemble and is space-saving and which should be able to provide externally adjustable, partial lift stops for both closure members. Said object is attained in that a piston (107) of a first individual adjustment device (1b) for the partial open position (T1) of the independently driven closure member (4) is displaceably arranged, to form a seal, externally in a drive housing (100) of the drive device (1), and a piston (108) of a second individual adjustment device (1c) for the partial open position (T2) of the dependently driven closure member (5) is displaceably arranged, to form a seal, externally in a cylindrical recess (107a) of the piston (107), which recess faces a main adjustment device (1a).
