Pressure actuated sensor switch with bobbin, trip cord and breakwire |
摘要 |
A spring loaded trip string holding bobbin is deployed when a gas pressure supply is activated. The gas pressure forces a diaphragm member to move a detented biased camming release ring from a locking position to a deploying position. The initial movement of the release ring permits detent balls to move and release a sleeve element which holds the bobbin locked to a sensor assembly and initially prevents the movement of a post holding a breakwire sensing element which is attached to the personnel extended trip string. The release ring after a short interval of time automatically returns to its initial position unlocking the bobbin post so that the breakwire and the device will be responsive to string disturbance.
