FIELD: mechanical engineering.
SUBSTANCE: invention relates to the field of mechanical engineering, in particular to shut-off valve drive devices. The shut-off valve drive device contains a worm gear housing, the worm wheel of which is connected to the output element of the shut-off valve drive, made in the form of a standard rod having a threaded hole. The worm shaft of the worm gear is connected to the shaft of the controlled electric motor. In this case, the mentioned connection of the worm wheel with the output element of the shut-off valve drive is made in the form of a transition plate placed on the said rod, with the exception of rotation relative to it, located in a similar-shaped recess made on the side of the worm wheel with the possibility of transmitting rotation from the worm wheel to the locking element of the shut-off valve. In this case, the mentioned wheel is supported by a bearing on the housing and fixed on the said rod by a locking sleeve connected to this rod. The housing of the controlled electric motor is connected to the said worm gear housing and is kinematically connected to the pipeline with the possibility of dismantling the shut-off valves.
EFFECT: invention is aimed at reducing the weight and size parameters of the drive device, increasing the service life by increasing the reliability of the drive and simplifying the design of the device.
