When needing automatically controlled closing valve, "Off" button is pressed, motor 21 obtains electric reversion, drives retarder 22 to rotate, in retarder 22
Decelerating effect under, the output shaft that the output shaft speed of retarder 22 is less than motor 21 will slow down under the transmission of train 011
The power of 22 output shaft of device passes to shaft 3, and drive shaft 3 rotates, and the special-shaped wheel 4 that the rotation driving of shaft 3 is fixed thereon rotates,
Second convex block 43 moves closer to the second limit switch 6, and finally makes the pressure head of the second press surface 432 the second limit switch 6 of pressure,
At this point, the second position-limitting pin 10 being placed in the second limiting slot 431 be used for for shaft 3 rotation rise position-limiting action, adjust its
Position in second limiting slot 431, it is ensured that the second press surface 432 accurately depresses the pressure head of the second limit switch 6.And this
When, since the pressure head of the second limit switch 6 is depressed, the dump of motor 21 is controlled, motor 21 stops operating.Shape at this time
State are as follows: drive valve stem connection 8 to rotate by a certain angle when shaft 3 rotates, to drive the valve rod rotation one connecting with valve stem connection 8
Determine angle, realizes the closing of valve；Denso aperture pointer 7 is driven to rotate by a certain angle when shaft 3 rotates, from observation window 121
Scale mark can be seen that Denso aperture pointer 7 at this time and be directed toward the indicating positions that valve is closed, and understand valve convenient for related personnel
State.
