Abstract

The invention discloses a comprehensive testing device for a rotary valve electric actuator. The comprehensive testing device comprises a base, a first cylinder, a second cylinder, an encoder, a movable friction disc, a fixed friction disc, a torque sensor and a coupler, wherein a mounting cavity is formed in the base, a mounting station for mounting an actuator is arranged at the top end of the base, a main shaft is arranged on the movable friction disc, the torque sensor and the main shaft are connected with an external actuator by means of the coupler, and the encoder is mounted on the movable friction disc, and the first air cylinder and the second air cylinder output alternately to generate variable pressure, so that the fixed friction disc generates variable friction forces on the movable friction disc, and the actuator is subjected to different torque. In the test process, the torque sensor tests the torque changes of the actuator, the encoder tests the rotation angle changes ofthe actuator, and the test values are compared with standards, so as to test whether the actuator is qualified or not. Through the arrangement, three key values of a valve can be tested at one time,the operation is convenient, and the efficiency is high.

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...
