Abstract

The invention discloses a rotation valve driving device. The rotation valve driving device is provided with a box body with a box cover arranged on the top portion of the box body. A servo motor is fixed on one side of the box body. Two rod-shaped guide rods and a screw rod are penetrated inside the box body in a horizontal mode, a sliding block is arranged on each guide rod in a sliding mode, and a pushing shaft is arranged on either side of the sliding block. The pushing shaft is plugged with a pushing fork, and a driving shaft is fixed on the upper end of the pushing fork. A bearing is fixed on either end of the driving shaft through a right bearing cover. The rotation valve driving device has a large output torque, and is suitable for the driving device with a large-diameter ball valve and a butterfly valve, and has a function of remote control.

Description

technical field [0001] The invention relates to a valve driving technology, in particular to a rotary valve driving device. Background technique [0002] The electric drive devices on the existing rotary valves mostly have rack and pinion mechanisms, tie rod mechanisms, piston rod mechanisms, etc., and the output torque curve is a straight line, which is a parabola with the opening threshold torque characteristic curve of ball valves and butterfly valves. It is not suitable for remote control and as a driving device for large-diameter ball valves and butterfly valves. Contents of the invention [0003] In order to overcome the shortcomings of existing electro-hydraulic drive devices: the output torque curve does not match the opening and closing torque characteristic curves of ball valves and butterfly valves, it is not suitable for use as a drive device for large-diameter ball valves and butterfly valves, and it is not suitable for remote control; The invention provi...
