FIELD: mechanical engineering. ^ SUBSTANCE: automatic electric drive for valving has electric motor, commutator, valving member, spindle, reduction gear, indication block, and timer. The device is provided with the block for diagnosing the position of the valving member made of a pulse magnetic-inductive pickup whose stator is rigidly secured to the housing of the valving. The rotor is joined to the spindle for permitting rotation with respect to the stator when spindle moves. The first output of the control device is connected with the inlet of the commutator and the input of the timer. The second output is connected with the input of the indication block. The first, second, and third inputs are connected with the output of the block for diagnosing the position of the valving member, output of the commutator, and output of the timer, respectively. ^ EFFECT: expanded functional capabilities. ^ 1 dwg |
