The invention discloses a switch type torque adjusting mechanism of a multi-turn electric actuator. The switch type torque adjusting mechanism comprises a bracket, an overload device connecting shaft and a valve switch linkage component, wherein the valve switch linkage component comprises a driving gear, a cam and a torque driving assembly, and the driving gear is in driving connection with a cam shaft of the cam through the torque driving assembly. The switch type torque adjusting mechanism is characterized in that the torque driving assembly comprises a spline connecting shaft, a connecting sleeve, a driving wheel, a torque dial and an indicating dial, wherein the driving wheel is in matching driving with a cam shaft gear on the cam shaft, an upper external spline and a lower external spline are arranged on the spline connecting shaft, the driving gear is provided with an internal spline which is matched with the lower external spline, an internal spline of the connecting sleeve is matched with the upper external spline, and a spring sleeves the lower external spline of the spline connecting shaft. The switch type torque adjusting mechanism is convenient for adjusting the initial state and size of the torque, has the advantages of compact structure, small size and high precision and is suitable for different types of valves.
Description
technical field [0001] The invention relates to an improved invention of a switch-type torque adjustment mechanism, in particular to a switch-type torque adjustment mechanism of a multi-rotation electric actuator. Background technique [0002] The switch type torque adjustment mechanism of the existing multi-turn electric actuator has the problems of complicated structure, large volume and poor precision, and it is very inconvenient to adjust the torque and the initial state, and some of them cannot even be readjusted after leaving the factory. The adjustment brings a lot of inconvenience. Contents of the invention [0003] In view of the technical problems existing in the background technology, the technical problem to be solved by the present invention is to provide a switch-type torque adjustment mechanism of a multi-turn electric actuator that is small in size, compact in structure, and most importantly convenient to adjust the torque and initial state. [0004] In or...
