The top surface of the protective cover 10 is connected with a handle 14, and a transparent observation window 15 is provided on one side surface of the protective cover 10.

[0025] During specific use, the protective cover 10 is slid into the slide groove 9 on the mounting plate 4. At this time, the position of the fixing hole 13 on the protective cover 10 will coincide with the position of the limiting hole 11. The butterfly bolt 12 is then passed through the limiting hole 11 and screwed into the fixing hole 13, so that one end of the protective cover 10 can be fixed in the slide groove 9, so that the protective cover 10 is installed at the upper end of the mounting plate 4. In this way, the protective cover 10 will protect and shield the first bevel gear 7 and the second bevel gear 8, thereby preventing debris in the environment from falling onto the first bevel gear 7 and the second bevel gear 8 and accumulating.

[0032] Working implementation principle: when using the heating ball valve structure for heating, when the operator needs to control the ball inside the valve body 1 to rotate, the motor 6 is started through the switch, and the output end of the motor 6 drives the first bevel gear 7 to rotate, so that the first bevel gear 7 drives the second bevel gear 8 to rotate, so that the second bevel gear 8 will drive the valve stem 3 to rotate when it rotates, and the valve stem 3 will drive the ball inside the valve body 1 to rotate, thereby achieving the purpose of controlling the heating ball valve. This operation allows the operator to control the heating ball valve through the switch, avoiding the need for the operator to manually turn the handle to control the heating ball valve, thereby saving manpower and facilitating the operator's control of the heating ball valve. Secondly, by sliding the protective cover 10 into the slide groove 9 on the mounting plate 4, the position of the fixing hole 13 on the protective cover 10 will coincide with the position of the limiting hole 11, and then the butterfly bolt 12 is used to penetrate the limiting hole 11 is screwed into the fixing hole 13, so that one end of the protective cover 10 can be fixed in the slide groove 9, so that the protective cover 10 can be installed at the upper end of the mounting plate 4, so that the protective cover 10 will protect and shield the first bevel gear 7 and the second bevel gear 8, thereby preventing debris in the environment from falling onto the first bevel gear 7 and the second bevel gear 8 and accumulating, ensuring the cleanliness of the first bevel gear 7 and the second bevel gear 8, and preventing the accumulation of debris from affecting the operation of the first bevel gear 7 and the second bevel gear 8. The situation inside the protective cover 10 can be penetrated through the transparent observation window 15, so as to confirm the operating status of the internal parts of the protective cover 10. When the internal parts of the protective cover 10 need to be maintained, the butterfly bolt 12 is twisted to separate one end of the butterfly bolt 12 from the fixing hole 13.
