[0047] Working principle: When the valve needs to be opened, the motor 9 is started. The motor 9 drives the bevel gear 7 to rotate. During the rotation of the bevel gear 7, the bevel gear 6 will also rotate. The rotation of the bevel gear 6 will then drive the rotating shaft 5 to rotate. Since the rotating shaft 5 is fixedly connected to the fixed column 4, and the fixed column 4 is rotatably connected to the baffle 10, the fixed column 4 and the baffle 10 will rotate with the rotation of the rotating shaft 5, opening the interior of the outer shell 1, allowing liquid to pass through the interior of the outer shell 1. The user can control the degree of opening of the baffle 10 by controlling the speed of the motor 9, realizing the automated control of the valve, improving the remote control capability of the valve, and making valve management in large industrial pipeline systems more convenient and faster.

[0048] When the power system fails to operate, screw 206 is turned so that it passes through the fixing block 203 and enters the rotating column 204. Then, the connecting column 202 is pushed, which drives the rotating ring 201 and the fixing block 203 to rotate. The rotation of the fixing block 203 in turn drives the rotating column 204 to rotate, which in turn drives the bevel gear 6 to rotate. This opens the inside of the outer casing 1, allowing the liquid to flow out. This enables manual opening of the valve and prevents equipment failure due to power system malfunction, which could affect the work process.
