AI Technical Summary
In existing target-type flow switches, the target rod and the target core are integrally formed or welded, which makes it impossible to flexibly adjust the flow sensitivity and has poor compatibility, making it difficult to adapt to different models.
A detachable target structure was designed, which, through threaded connection and tilt setting, combined with anti-detachment components and a flip door, enables convenient replacement and fixation of the target, enhances compatibility, and provides good operating space during maintenance.
It enables convenient replacement of the target and compatibility with multiple models, prevents loosening, and improves the compatibility and maintenance convenience of the device.
