Abstract

The invention provides an actuator. The actuator comprises a transmission mechanism, a hand-operating mechanism and a locking mechanism; the hand-operating mechanism is used for driving the transmission mechanism to rotate and provided with a first position which is in driving connection with the transmission mechanism and a second position which is disconnected with the transmission mechanism; the locking mechanism is provided with a locking position and an unlocking position; when the hand-operating mechanism is located at the first position, the locking mechanism is located at the locking position so as to prevent the hand-operating mechanism from being separated from the transmission mechanism; and when the hand-operating mechanism is located at the second position, the locking mechanism is located at the unlocking position. According to the technical scheme, the problem that an actuator in the prior art is inconvenient to operate can be solved.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to an actuator. Background technique [0002] Actuators are generally used in the automatic control of valves. Driven by a motor, the valve can be precisely rotated to the required position under the action of the control signal. Actuators generally have two modes of operation, automatic and manual. Actuators currently on the market require manual intervention when switching between automatic and manual modes. After switching from automatic to manual mode, manual effort is required to keep the transmission parts and the motor disconnected, and the handwheel needs to be rotated to control the opening and closing of the valve. This has high requirements for workers, and it is very laborious to operate under some working conditions. Contents of the invention [0003] The invention provides an actuator to solve the problem of inconvenient operation of the actuator in the...
