摘要： A valve device comprising a body (1), a closure member (2) operated by a shaft (3) guided through a neck (4) in the body (1), and a liner (5) provided with a flange (6) extending along part of the length of the neck (4). The sealing contact between the shaft and the bore may be improved by means of a clamping assembly (7, 8, 9) positioned around the flange (6) in a space (10) in the body (1). The size of the clamping assembly (7, 8, 9) is such that it exerts a force on the flange (6) and thereby on the shaft (3). The clamping assembly (7, 8, 9) is radially and/or tiltably movable in said space (10) relative to the body (1). Said device is particularly suitable for butterfly valves for use with corrosive and/or delicate liquids such as liquid chemicals and liquid foodstuffs.

摘要： Mechanism for obtaining a couple for maneuvering a part to make it rotate on itself through a quarter turn, from a member moving along a trajectory, via a transmission such that the curve representing the reduction coefficient, which is the ratio of the maneuvering couple to a nominal couple, shown on the y axis, as a function of the angle of rotation, shown on the x axis, is convex, the curve rotating its convexity upwards and the peak coefficient of reduction being obtained for an angle of about 20 to 40°.

摘要： A clack valve includes a housing having a circumferential groove. A rotatable valve disk is disposed within the housing. A gap of constant width at any axial cross-section through the disk is defined between the valve disk and the circumferential groove of the housing. A valve shaft passes from the rotatable valve disk into the housing. An elastic sealing cup has a passage opening for the valve shaft. The elastic sealing cup is disposed between the circumferential groove of the housing and the valve disk to seal the valve disk and the valve shaft against the housing. The elastic sealing cup has a curved circumferential flange to engage the circumferential groove. The curved circumferential flange has a material accumulation in a region of the passage opening. The material accumulation is created by an increase of a thickness of the curved circumferential flange to a maximum thickness in the region of the passage opening for the valve shaft.
