Abstract

The invention discloses a comprehensive testing device for a rotary valve electric actuator, which comprises a base, a first cylinder, a second cylinder, an encoder, a movable friction disc, a fixed friction disc, a torque sensor and a shaft coupling. cavity, the top of the base is provided with an installation station for installing the actuator, the movable friction disc is provided with a main shaft, the torque sensor and the main shaft are connected with the external actuator through a coupling, and the encoder is installed on the movable friction disc. The output of the first cylinder and the second cylinder alternately generates varying pressures, so that the fixed friction discs produce varying frictional forces on the movable friction discs, thereby causing the actuator to receive different torques. During the test process, the torque sensor tests the change of the actuator torque, the encoder tests the change of the rotation angle of the actuator, and compares the test value with the standard to test whether the actuator is qualified. Through the above settings, three key values ​​of the valve can be tested at one time, which is easy to operate and high in efficiency.

Description

technical field [0001] The invention relates to a valve testing device, in particular to a comprehensive testing device for a rotary valve electric actuator. Background technique [0002] The actuator is an essential and important part of the automatic control system. Its function is to accept the control signal sent by the controller, change the size of the controlled medium, so as to maintain the controlled variable at the required value or within a certain range. [0003] Actuators can be divided into linear and rotary. Rotary actuators have three key technical indicators: rated angular deviation, output torque value and life. In the existing test process, these three parameters are tested separately, and different equipment needs to be replaced during the test process, which is troublesome to operate. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a comprehensive testing device for r...
