<p>The invention relates to a chassis aggregation for monitoring-, control- and regulation systems for a process valve (1), which features at least one valve rod with a closing member and one pressure medium loaded drive (1b) for the valve rod(s). The invention assures that a chassis configuration of modular structure of the type initially described satisfies high hygienic demands and that it can be adapted in manifold ways and easily to the various demands and conditions of the process. This is achieved by the fact that the respective chassis aggregation (I, II, III, IV) is mounted on the respective drive (1b) with a positive friction fit by means of a rotation symmetrical cover part (6), by the fact that the chassis aggregation (I, II, III, IV) can also be optionally assembled from a first chassis upper part (2), a second chassis upper part of first, second, third type (3, 3*, 3**), and a first or second cover (4, 4.1), by the fact that the chassis upper part (2, 3, 3*, 3**) and the cover (4, 4.1) are each developed as rotation symmetrical bodies with cylinder-shaped exterior contours, by the fact that joining points (6/2, 2/4; 6/3, 3/4; 6/3, 3/3*. 3*/4; 6/3, 3/3**, 3**/4.1) are designed between the cover part (6), the chassis upper part (2, 3, 3*, 3**), and the cover (4, 4.1) of the respective chassis aggregation (I, II, III, IV), at which, when seen in meridian section, the surface line of the cover part (6), the body of the chassis upper part (2, 3, 3*, 3**), and the cover (4, 4.1) are arranged next to each other with the same diameter, flush, without gaps or breaks, by the fact that all of the joining points are sealed against each other, and by the fact that the respective joining partners are centered and connected to each other with a positive friction fit at all of the joining points (see figure 1).</p> |
