When in use, the manual driving component 22 and the automatic driving component 23 can both independently control the opening and closing of the valve body 1. During normal use, the automatic driving component 23 can perform automatic control. When a power outage or an emergency occurs, the opening and closing of the valve body 1 can be manually controlled by the manual driving component 22. The display device 24 is convenient for observing whether the valve body 1 is open. When the ball valve is opened, the flowing water is conducted through the connecting pipe 243, so that part of the water flows into the display tube 242, so that it is only necessary to check whether the water in the display tube 242 flows to conveniently determine whether the valve body 1 is open.

[0024] The valve body 1 includes a ball valve outer shell 11, the interior of the ball valve outer shell 11 is rotatably connected to the valve core 12, the interior of the rectangular shell 21 is rotatably connected to the first bevel gear 13, the manual drive component 22 includes a second bevel gear 221 rotatably set in the rectangular shell 21, and the automatic drive component 23 includes a third bevel gear 231 rotatably set in the rectangular shell 21.

[0025] Specifically, the rotation of the second bevel gear 221 and the third bevel gear 231 can drive the first bevel gear 13 to rotate. The rotation of the first bevel gear 13 controls the rotation of the valve core 12, thereby controlling the opening and closing of the valve body 1.

[0026] The end of the first bevel gear 13 extends into the ball valve outer shell 11 and is fixedly connected to the circumference of the valve core 12 . The second bevel gear 221 and the third bevel gear 231 are both meshed with the first bevel gear 13 .

[0032] The display tube 242 is a transparent tube body, and a rectangular shell 21 extends from the periphery of the display tube 242 . The end of the display tube 242 is fixedly connected with a water outlet 244 . The end of the water outlet 244 passes through the rectangular shell 21 , and a sealing plug is provided at the end of the water outlet 244 .

[0033] Specifically, the setting of the transparent tube body enables a clearer display of the flow of liquid in the tube display tube 242, and the setting of the water outlet 244 enables the sealing plug to be opened when judgment cannot be made through the display tube 242. When water flows out, the valve body 1 is in an open state, and the end of the connecting tube 243 is connected to the water flow cavity in the valve core 12, and the end of the connecting tube 243 is rotatably connected to the valve core 12.
