Abstract

The invention discloses a switching mechanism for a dial-block type valve electric actuator. The switching mechanism comprises a switching handle component, a dial-block component, a dial-block frame and an output shaft component, wherein the output shaft component is arranged inside a box body; the dial-block frame is arranged on the output shaft, one end of the dial-block frame is arranged on a lug of a box body wall and rotationally connected with the lug, and the other end is provided with a groove; the switching handle component is installed at one side of output shaft component; and the dial-block component is installed at one end of the switching handle component; a pin on the dial-block component is connected to the groove of the dial-block frame. By adopting a structure of the switching mechanism, a switching force is reduced; a switching handle can be automatically reset without misoperation after being pressed down; and therefore, the switching mechanism is simple and compact in structure.

Description

technical field [0001] The invention relates to a switching mechanism for a shifting block type valve electric device. Background technique [0002] All valve electric devices should be equipped with a manual operating mechanism. In order to change the working conditions, there should also be a switching means, that is, a manual → electric switching mechanism. According to the function, it can be divided into three forms: full manual switching, fully automatic switching and semi-automatic switching. According to the installed position, it can be divided into two forms: switching on the high-speed shaft and switching on the low-speed shaft. When the output torque of the valve electric device is small, a semi-automatic switching mechanism switching on the low-speed shaft is generally used. The switching form used in the low-speed shaft switching of the original valve electric device: the multi-stage gear transmission of the motor to the worm shaft, the worm shaft has a worm ...
