Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a ball valve capable of real-time detection. Background Art

[0002] A ball valve is a valve in which the opening and closing member (ball) is driven by the valve stem and rotates around the valve axis. It can also be used for fluid regulation and control. The hard-sealed V-shaped ball valve has a strong shear force between the V-shaped ball core and the metal valve seat with hard alloy overlay, making it particularly suitable for media containing fibers and small solid particles.

[0003] Existing ball valves lack the function of real-time detection. When the air pressure inside the ball valve fluctuates abnormally, it cannot automatically close, which easily leads to safety accidents such as gas leakage. Therefore, a ball valve with real-time detection is proposed. Utility Model Content

The automatic driving mechanism consists of a detection component and a transmission component, and the detection component consists of an air pressure sensor 12 and a relay 15. An external thread 13 is provided on the outer wall of the sensing head of the air pressure sensor 12, and a threaded hole 14 extending to the interior of the extension housing 2 is provided on the outer wall of the extension housing 2. The sensing head of the air pressure sensor 12 and the threaded hole 14 are threadedly matched with each other, and a mounting seat 18 is also fixedly installed on the outer wall of the extension housing 2, and a relay 15 is fixedly installed on the mounting seat 18. The relay 15 is connected to the air pressure sensor 12 signal, and the relay 15 is electrically connected to the transmission component.

[0021] Among them, the transmission assembly consists of a driven gear 5, a motor 16 and a driving gear 17. The motor 16 is fixedly connected to the upper end of the mounting base 18. The motor 16 is electrically connected to the relay 15. The driving gear 17 is fixedly installed at the end of the output shaft of the motor 16. The driven gear 5 is sleeved on the outer wall of the rotating shaft 4. The driven gear 5 is fixedly connected to the rotating shaft 4, and the driven gear 5 and the driving gear 17 are engaged with each other.

[0022] During use, the motor 16 drives the driving gear 17 to rotate, thereby driving the driven gear 5 to rotate, the driven gear 5 drives the rotating shaft 4 to rotate, and the rotation of the rotating shaft 4 drives the ball 11 to rotate.

[0023] The diameter of the driving gear 17 is smaller than the diameter of the driven gear 5 .

[0024] With such an arrangement, a labor-saving gear set can be formed between the driving gear 17 and the driven gear 5 , thereby reducing the stress on the output shaft of the motor 16 .
