Abstract

The invention relates to a linear thrust output device. The device comprises a thrust conversion assembly, a coupling assembly and a support assembly; the thrust conversion assembly is mounted on andconnected to a support upper flange of the support assembly through a shell on the assembly, the upper portion of the thrust output device is connected with a valve electric execution mechanism through a connecting disc on the upper end of the thrust conversion assembly, and the lower portion of the thrust output device is connected with a valve to be driven through a support lower flange of the support assembly. The device is simple in structure, flexible in configuration, convenient to mount and connect, wide in application range and the like, and the device is combined and matched with a multi-rotation-valve electric execution mechanism to output linear stroke and thrust.

Description

technical field [0001] The invention relates to a valve electric actuator used in the field of process control, in particular to a linear thrust output device for the valve electric actuator. Background technique [0002] In the field of process control, many valves realize the opening and closing of the valve by driving the valve core to do linear reciprocating motion through the valve stem, which requires that the electric actuator matched with this type of valve must output linear stroke and thrust, and Rotational motion and torque are not output directly. At present, most of the types of linear stroke and thrust output are integrated valve electric actuators. The integrated output linear stroke and thrust output electric actuator type is highly targeted and has a narrow scope of application. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the integrated output linear stroke and thrust output electric actuator...
