    摘要: An actuator having a tubular body with a cylindrical bore therein within which a piston reciprocates, an output shaft extending into said bore and a linkage for converting the linear movement of the piston into the rotary motion of said shaft. The linkage is contained entirely within said bore. In one form the piston is spring loaded and a spring follower also provides a piston for compressing the spring to permit the force exerted on the piston to be transmitted to the output shaft substantially in its entirety.

    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: A gasket, which functions as a static radial seal, includes a first sealing ring disposed at a first predetermined distance from a longitudinal axis. A second sealing ring is disposed at a second predetermined distance from the longitudinal axis. The second distance is less than the first distance. The first and second sealing rings are made of metal. A common metal C-shaped casing envelopes the first and second sealing rings. The first and second sealing rings move between a relaxed position prior to installation and an engaged position after installation. The first and second sealing rings are positioned in the casing in the relaxed position and define a line that extends between the centers of the first and second sealing rings. This line is disposed at an oblique offset angle with respect to the longitudinal axis.

    摘要: A sealing device for providing the upstream/downstream sealing of a valve comprising a valving member movable inside the bore of a tubular body and comprising at its periphery a sealing surface coming to bear on a sealing packing mounted in the body at the end of the valving stroke. This sealing packing comprises a dynamic annular sealing element and a coronal metal membrane, whose outer edge portion has flat radial part applied axially against a steep side of a shoulder in the bore of the body, for providing static sealing therewith.

    摘要: The valve of the present invention comprises a tubular body (1) the centralortion (6) of which defines a shutoff chamber (7) which is accessible via an inspection trap (15). Within this chamber (7) there is housed a removable annular pre-body (8) provided with two radial boreholes (9, 10) serving for the rotary mounting of the shaft (11) of the butterfly (12). Sealing means which cooperate with the body (1), the pre-body (8) and the butterfly (12) make it possible to assure the upstream/downstream tightness of the valve. The inspection trap (15) is closed by a cap (28) provided with a passage within which there is rotatably mounted a drive shaft (35) which is coupled to the shaft (11). This structure permits greater ease of access to the inner parts of the valve, a decrease in volume and weight, and greater ease in manufacture.
