A valve actuator that is easy to install and disassemble

Abstract

The invention discloses a valve actuator convenient to mount and demount. The valve actuator comprises an actuator body, wherein the bottom end of a base is connected with an actuator-body support frame; two sides of the base are connected with first bolts, which run through the surface of the base and extend into the actuator-body support frame; a valve body is arranged at the bottom end of the actuator-body support frame; second bolts are arranged on two sides of the bottom end of the actuator-body support frame; pipeline connecting mechanisms are arranged at two ends of the valve body; theends, of the pipeline connecting mechanisms, away from the valve body, are connected with guide pipes; second fixed pipes are arranged in first fixed pipes; and fastening bolts run through fixed plates. According to the valve actuator, through the provided first bolts, the actuator body and the actuator-body support frame can be demounted conveniently, and through the provided second bolts, the actuator-body support frame and the valve body can be demounted conveniently, so that the valve actuator is easy to mount and demount and convenient to maintain and replace; through the provided pipeline connecting mechanisms, the valve body and the guide pipes can be demounted conveniently; and therefore, the applicability of the valve actuator is improved.

Description

technical field [0001] The invention relates to the technical field of valve actuators, in particular to a valve actuator that is easy to install and disassemble. Background technique [0002] Actuator is in the automatic control system of industrial production process, which takes the signal of adjusting instrument or other control device as the input signal, and adjusts the input quantity of the controlled object according to a certain regulation rule. Valve actuator is a commonly used one in industrial intelligent control system. A valve actuator. [0003] The installation of the existing valve actuator is relatively complicated, and it cannot be disassembled and moved to different pipelines. The long maintenance time leads to low work efficiency and affects production efficiency. Moreover, the stability and sealing of the valve actuator are poor, and it cannot be applied to pipelines of different sizes. . Contents of the invention [0004] The purpose of the present ...
