Elektromotorisk regleranordning för spärrventil |
摘要 |
<p>A valve has a housing having a nonrotatable polygonal-section stem centered on a valve axis and a spindle coaxial with the stem, projecting axially therefrom, and formed with at least one peripheral tooth. A valve actuator has an electric drive motor having a housing and a drive shaft projecting from the housing along the axis and a sleeve fixed to the drive-motor housing coaxially with the shafts and formed with a seat complementarily engageable with the polygonal-section stem. Thus the sleeve and drive-motor housing are rotationally locked to the stem. A coupling fixed on the drive shaft fits complementarily over the spindle at the tooth thereof to rotationally interconnect the spindle and drive shaft and a rotary potentiometer in the sleeve between the coupling and the drive motor has a rotary part fixed on the drive shaft and a nonrotating part fixed on the motor housing.</p> |
