AI Technical Summary
In existing control valve performance testing equipment, the clamping rod tends to rotate when sliding under the action of the cylinder, which leads to unstable sliding of the air tube and affects the testing accuracy.
The system employs a ring column and a second guide groove structure. The ring column positions the first threaded rod, and the second guide groove guides the L-shaped plate to slide. Combined with a servo motor driving the sliding block, it ensures the stability of the inflation tube's fixation and sliding.
It improves the ease of fixing the inflation tube and the stability of its sliding, reduces the risk of rotation and sliding tilt of the threaded rod, and enhances the operational reliability of the testing equipment.
