Working Principle

when the system pressure is above the rated
security pressure, the pressure induction disk within the sensor moves in stantaneously, the security disk through a guide rod is driven to the lock location, while the security disk pushes the switch touch
point to disconnect through the connected guide rod
when the pressure drops to the rated security pressure below, the induction disks automatically reset while as these curity disk has been at the
lock location and cannot be automatically reset, the switch touch point cannot be connected, and the system can return to the normal working condition only by pressing the external button and forcing to
push the security disk lock to the switch touch point into the connected state
