Vacuum Logical Valve P2V Combined With Vacuum Suction Cup For
Handling Workpieces
1. Operation principle in application
- When a vacuum generator is provided with a plurality of suction
cups, and the suction cups do not absorb the workpiece, the vacuum
degree can be limited to drop.
- When the vacuum suction cups does not catch the workpiece, the
valve core will be closed by the air flow , and the flow can only
pass through the fixed throttle aperture. At this time, each fixed
throttle aperture can suck the corresponding air; When the vacuum
suction cup catch the workpiece, the suction flow decreases, the
valve core will be opened by the spring force , and the suction
flow between the valve core and the housing will open.
