Working principle of the present invention is:
Underwater valve actuator is passed through on low-power holding mechanism shell 14 by driving mechanisms such as hydraulic or electric power
Hole pushes underwater valve rod 1 from off state to open state；In the open state, in lock ball 8 and underwater valve rod 1
The groove in portion is powered on a horizontal line to electromagnet element 18, and electromagnet generates magnetic force and magnetic disk 13 is sucked to moving down
It is dynamic, brace 5 is locked at this time, the spring force of locking reset spring 11 is overcome to move down, pass through the slope driving on locking brace 5
Locking sliding block 9 is displaced outwardly, and then lock ball 8 is pushed to enter in the groove inside underwater valve rod 1, is stopped at this time hydraulic
Or the power such as electric power, safe shutdown reset spring 3 give 9 one centripetal force of lock ball 8 and locking sliding block, locking is centripetal when keeping
Power and the angle for locking 5 inclined-plane of brace are larger, therefore no matter this power is much, are transferred to power on locking 5 moving direction of brace all
Very little, it is only necessary to which lesser magnetic force can be kept, and the low-power for realizing underwater valve actuator keeps function.
When system, which breaks down, to fail, the power-off of electromagnet element 18 loses magnetic force, and locking reset spring 11 pushes locking
Brace 5 moves up, and lock ball 8 is inwardly pushed locking sliding block 9 by the thrust of safe shutdown reset spring 3 at this time, works as locking
When ball 8 is completely into in low-power holding mechanism shell 14, underwater valve is under the action of safe shutdown reset spring 3 from opening
State is opened to closed state, realizes the fail-safe turn-off function of underwater valve.
To sum up, the present invention realizes low-power holding and safe shutdown by the magnetic force on inclined-plane and electromagnet on locking brace
Function effectively reduces the energy consumption of underwater valve, and the low-power of design is kept and fail-safe shut-down mechanism principle simply may be used
It leans on, the low-power for effectively realizing underwater valve is kept and fail-safe turn-off function.
