[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 5As shown, this utility model provides a novel anti-accidental opening and closing ball valve, including a ball valve body 1. An actuator 3 is rotatably mounted on the outer surface of the ball valve body 1, and the actuator 3 extends into the ball valve body 1. A positioning groove 2 is provided on the outer surface of the front of the actuator 3. A fixing head 5 is fixedly connected to the top of the actuator 3. An annular groove 4 is provided between the actuator 3 and the fixing head 5. A protective cover 7 is movably sleeved on the outer surface of the actuator 3. A tension spring 8 is fixedly connected to the top of the inner side of the protective cover 7. A rectangular groove 12 is provided on the front of the protective cover 7. A rotating shaft 13 is rotatably mounted on the inner side of the rectangular groove 12. A torsion spring button 11 is movably mounted on the outer surface of the rotating shaft 13, and the rotating shaft 13 passes through the torsion spring button 11. A positioning torsion spring 9 is movably sleeved inside the torsion spring button 11 on the outer surface of the rotating shaft 13. A torsion spring anchor point 10 is provided on the inner side of the rectangular groove 12, and the torsion spring anchor point 10 is fixedly connected to the positioning torsion spring 9.

[0019] When the operator presses the torsion spring button 11 with external force, the rotating shaft 13 will start to rotate. When the rotating shaft 13 starts to rotate, it will drive the positioning torsion spring 9 to start to rotate. Since the outer surfaces of both sides of the positioning torsion spring 9 are fixedly connected to the torsion spring anchor point 10, the positioning torsion spring 9 is fixed and achieves lever movement. As a result, the buckle on the inner side of the torsion spring button 11 is connected and disengaged from the ball valve body 1 due to the lever movement of the positioning torsion spring 9. When connection is required, the external force on the torsion spring button 11 disappears, and the elastic recovery effect of the positioning torsion spring 9 causes the torsion spring button 11 to return to its original position, thereby achieving connection.

[0020] Pressing the torsion spring button 11 will cause the rotating shaft 13 to start rotating. When the rotating shaft 13 starts rotating, it will cause the positioning torsion spring 9 to start rotating. Since the outer surfaces of the two sides of the positioning torsion spring 9 are fixedly connected to the torsion spring anchor point 10, the positioning torsion spring 9 is fixed and achieves lever movement. As a result, the buckle on the inner side of the torsion spring button 11 is connected and disengaged from the ball valve body 1 due to the lever movement of the positioning torsion spring 9. Compared with traditional devices, this device can prevent the ball valve from accidentally opening or closing, thus preventing the accidental leakage of dangerous media and avoiding serious accidents such as personal injury and environmental pollution. It can ensure the safety and stability of the system, ensure that the ball valve operates according to the predetermined procedures and conditions, maintain the stable operation of the system, and reduce system failures and downtime caused by valve misoperation.

[0021] A tension spring 8 is fixedly connected to the top inner side of the protective cover 7, and the tension spring 8 is located at the top of the fixed head 5.

[0022] Through the design of the tension spring 8, when pressed down, the tension spring 8 will generate a reverse force due to the elastic recovery effect, so that the torsion spring button 11 can be better embedded in the positioning slot 2. After unlocking, the protective cover 7 can be pulled upward to pop out.

[0023] Among them, a valve handle 6 is fixedly installed on the outer right side of the protective cover 7, and a connecting rod is fixedly installed on the outer right end of the valve handle 6.

[0024] When the valve handle 6 is rotated, and the torsion spring button 11 is inserted into the positioning slot 2, rotating the valve handle 6 will cause the protective cover 7 and the actuator 3 to rotate together. When the actuator 3 rotates, it will cause the ball inside the ball valve body 1 to rotate, thereby realizing the opening and closing function of the ball valve body 1. This makes the extended lever arm more labor-saving during the opening and closing of the ball valve body 1.

[0025] The actuator 3 is fixedly connected to a fixed head 5 at its top, and an annular groove 4 is provided between the actuator 3 and the fixed head 5.

[0026] By pressing the torsion spring button 11, the positioning torsion spring 9 is moved. Due to the restoring effect of the tension spring 8, it can move up and down within the effective stroke, allowing the torsion spring button 11 to be better embedded in the annular groove 4. After unlocking, the protective cover 7 can be pulled upwards and popped out. When the inner buckle of the torsion spring button 11 is embedded in the annular groove 4, it can rotate freely 360° without driving the actuator 3.

[0027] The protective cover 7 has a rectangular groove 12 on its front side, and the inner side of the rectangular groove 12 is smooth.

[0028] The rectangular groove 12 design makes it easier to press the torsion spring button 11 without causing jamming, thus reducing the failure rate.

[0029] Working principle and usage process of this utility model:

[0030] When the operator presses the torsion spring button 11 with external force, the rotating shaft 13 will start to rotate. When the rotating shaft 13 starts to rotate, it will drive the positioning torsion spring 9 to start to rotate. Since the outer surfaces of both sides of the positioning torsion spring 9 are fixedly connected to the torsion spring anchor point 10, the positioning torsion spring 9 is fixed and achieves lever movement. As a result, the buckle on the inner side of the torsion spring button 11 is connected and disengaged from the ball valve body 1 due to the lever movement of the positioning torsion spring 9. When connection is required, the external force on the torsion spring button 11 disappears, and the elastic recovery effect of the positioning torsion spring 9 causes the torsion spring button 11 to return to its original position, thereby achieving connection.
