Abstract
953,824. Valves. K. R. ELLIOTT. Sept. 21, 1962, No. 35968/62. Heading F2V. An actuator for a valve having a rotatable stem 12 comprises a lever 32 connected to the stem and pivotally connected at 64 to a link 62. The other end of the link is pivotally connected at 60 to a nut 56 movable on rotation of an axially fixed-threaded shaft 47. The shaft is mounted in bearings 45 outside the arc of movement of the lever and the lever and link are such that with the nut in an end position on the shaft, the link 62 is parallel to the shaft axis thereby providing maximum thrust at the commencement of actuation. The nut and thread are preferably of the ball-screw type. The stem 12 may also carry a positive indicator 39. The shaft may be rotated manually by a handle 23 through helical gears 53, 54 or by an electric or hydraulic motor 21 through gears 49 and pinion 50. The nut 56 may be provided with a cam block 57 to operate trip members 25. The stem may be held in an intermediate position by any suitable device, for example, a magnetic brake may be connected to the motor shaft 51 for engagement when the electric motor 21 is de-energized.
