The lock control assembly includes a motor 10, a lock guide block 11, a lock connection block 12, a lock tongue 13, a lock shell 14, and a lock position column 15. The motor 10 is fixed to the main housing 8 by bolts through the lock shell 14 in a detachable manner, so that the motor 10, the lock shell 14 and the main housing 8 form a whole. A limit groove is provided in the lock shell 14, and the output shaft of the motor 10 is threadedly connected with the lock guide block 11 and the lock connection block 12 in the limit groove, so that the lock guide block 11 and the lock connection block 12 are limited by the limit groove, so that the motor 10 is powered on and the output shaft drives the lock guide block 11 and the lock connection block 12 to move in the limit groove. The lock connection block 12 is threaded or detachably fixed by bolts and vertically connected with a lock position column 15, so that the lock position column 15 and the lock connection block 12 are connected together to form a whole, so as to achieve simultaneous movement. The lock shell 14 is provided with a movable hole connected to the limiting groove, and one end of the locking column 15 passes through the lock shell 14 through the movable hole, so that the movement of the locking column 15 in the limiting groove along with the lock connecting block 12 will not be affected by the movable hole.

Two extension pieces extend from the sensing piece 16, and the two extension pieces correspond to the upper position sensor 21 and the lower position sensor 22 respectively, so that the rotation of the rotating shaft 5 drives the sensing piece 16 to rotate, thereby realizing the rotation of the two extension pieces on the sensing piece 16. When the two extension pieces rotate to the positions of the upper position sensor 21 and the lower position sensor 22 respectively, corresponding sensing signals are generated respectively. The circuit board 18 is electrically connected with a locking sensor 19 and an unlocking sensor 20 that match the lock control component.

[0024] When in use, when the device needs to lock the valve, the control valve assembly drives the valve core 2 to rotate to the valve closing state under the action of the handle 4. At this time, the motor 10 drives the lock tongue 13 to insert into the positioning hole of the positioning plate 9 to achieve locking. At the same time, one of the two extension pieces of the sensor plate 16 moves to the lower position sensor 22, and the other moves away from the upper position sensor 21; the locking position column 15 moves to the position of the locking sensor 19. When the device needs to lock the valve, the motor 10 drives the lock tongue 13 to disengage from the positioning hole of the positioning plate 9 to achieve unlocking. At this time, the control valve assembly can rotate freely, the handle 4 drives the valve core 2 to rotate to the valve opening position, the locking position column 15 moves to the unlocking sensor 20, and one of the two extension pieces of the sensor plate 16 moves to the upper position sensor 21, and the other moves away from the lower position sensor 22.
