  • the attendant When a power failure occurs, or when power is not available, the attendant removes the handwheel (not shown) from the handwheel shaft.
  • the drive block 140 and key 144 are on the handwheel shaft 161 and the handwheel mounts directly on the drive block 140).
  • the clamp-receiving adapter device 150 (Figs. 5-6) is permanently mounted on the valve actuator housing 160. The lceyway end of the handwheel shaft 161 projects into the circular axial bore of the adapter 150.
  • the attendant then mounts the clamp device 120, flexible coupling 135 and pin 147 on one end or the other of the gear reducer output shaft 60 (Fig. 3) according to the direction of rotation desired. If the valve is to be closed, the attendant mounts the clamp device 120 at one end, as for example, on the end plate 111 and bolts it in place as by bolts 124, as illustrated in Fig. 3. If the valve is to be opened, the attendant mounts the clamp device 120 at the other end of the output shaft 60. To do so, he first removes cover plate 170 (Fig. 3). (The drive block 141 and key 145 are supplied on both ends of the output shaft 60.)
  • the attendant With the clamp device 120 bolted in the desired position to the housing of the gear reducer 30, the attendant is now ready to mount the portable drive unit comprising the gasoline engine 10 and the gear reduction unit 30 (Fig. 1) onto the valve actuator. But before doing so, he first starts the gasoline engine 10. With the gasoline engine 10 running at idling speed, the centrifugal clutch 21-22 does not transmit energy to the gear reducer 30.
  • the flexible coupling 135 is inserted on the square drive block 140 on the handwheel shaft.
  • the pivotal clamps 125 of clamp device 120 are then secured onto the ears 154 of the clamp-receiving adapter device 150 and the volts 132 tightened and locked as by locknuts 133 (Fig. 6).
  • the speed of the two-cycle or four-cycle gasoline engine 10 is accelerated.

  • gear 40 drives clutch member 50 (Fig. 3).
  • clutch 50 If clutch 50 is in the position shown in Fig. 3, the clutch 50 through lug-on-lug engagement at 86, drives pinion 85, gear 91, shaft 90, gear 92 and gear 95, and through lug on-lug engagement at 97 drives a second clutch member 100. Since second clutch member 100 is splined to output shaft 60, output shaft 60 is driven. Since the gear train shown in Fig. 2 is a speed-reducing arrangement, output shaft 60 is driven at a reduced speed, relative to that of input gear 40, but the direction of the drive is not changed.
  • the speed-reduction path just described is preferably used during final closing and seating of the valve when low speed and high torque are desirable. Low speed and high torque may also be desired when opening a stuck valve. At other times, i.e., during stroking of the valve, high speed and low torque are preferable.
  • the attendant shifts the clutches 50 and 100 to the right from the position shown in Fig. 3. He does this by operating lever 79 (Fig. 2) to turn pivot shaft 78 (Figs. 2-3). This rotates gear 77 and causes rack 75 to shift axially to the right relative to output shaft 60. This shifts fork 70 to the right, and since fork rollers 72 and 172 are in grooves 52 and 102, respectively of clutch members 50 and 100, respectively,the two clutch members 50 and 100 are shifted to the right when the lever 79 is operated as just described.
  • gear 40 no longer drives the speed-reducer gear train.
  • gear 40 drives collar 45 through splines 51, clutch member 50 and lugs 54 and 46. Since collar 45 is keyed to output shaft 60, output shaft 60 is driven. The direction of rotation of shaft 60 is the same as when the shaft is driven through gear train 85, 91, 92,95 but the speed is greater.
  • the portable drive unit is reversed and the coupling to the handwheel shaft 161 is made at the other end of the gear-reducer output shaft 60.
  • Handles H shown in Fig. 1 are used to lift the carry the portable unit.
  • the gasoline engine 10 is rigidly mounted to the housing 20 of the centrifugal clutch through vibration dampers 14 (Figs. 1-2) to minimize the transmission of vibration to the gear reduction housing or gear box 30.
  • the gear box 30 is rigidly mounted to the valve actuator 160 by way of the adapter mechanism comprising the clamp 120 and clamp receiver 150.
  • Clamp 120 utilizes dampers 134 (Fig. 3) to control vibratory stresses in these adapter pieces.
  • the handwheel shaft 161 of the valve actuator is coupled to the gear box 30 through the resilient sleeve coupling 135 which absorbs misalignment between the gear box output shaft 60 and the handwheel shaft 161 of the valve actuator.
  • a two-speed gear reducer unit has been illustrated and described but a single speed unit is also provided.
  • the single speed unit has not been specifically illustrated since its construction would be obvious in view of what has already been described.
  • the two-speed unit has certain advantages. lt will be seen that the present invention provides a portable drive unit which may be used in case of power failure to operate large valve actuators. The unit replaces manual operation which has heretofore been used but which has the disadvantages, so far as the larger valves are concerned, of requiring a large number of handwheel turns at considerable physical effort.

Abstract

Un groupe portatif d'entraînement pour un dispositif d'actionnement de vanne comprend un moteur portatif à essence à deux temps ou à quatre temps (10) et un dispositif à engrenage de réduction (30). Le moteur à essence est boulonné, au travers des moyens d'amortissement de vibration (14) sur l'enceinte ou boîte de vitesse du dispositif à engrenage de réduction. La boîte de vitesse est bridée sur le dispositif d'actionnement de vanne par l'intermédiaire d'une bride annulaire (120) et une structure (150) adaptée pour recevoir la bride qui comprend également un moyen d'amortissement de vibration (134). Un accouplement à manchon flexible (135) dans l'alésage de la bride annulaire et de la structure d'adaptation de la bride effectue l'accouplement de l'arbre de sortie (60) du dispositif à engrenage de réduction avec l'arbre d'entrée du volant (161) du dispositif d'actionnement de la vanne.
