Description

Technical Field

[0001] The utility model relates to the field of pneumatic ball valves, in particular to a low-noise pneumatic ball valve. Background Art

[0002] A pneumatic ball valve is a ball valve equipped with a pneumatic actuator, and the noise generated during control is low. The execution speed of the pneumatic actuator is relatively fast, with the fastest switching speed being 0.05 seconds per time, so it is also commonly called a pneumatic quick-cut ball valve. Pneumatic ball valves are usually equipped with various accessories, such as solenoid valves, air source treatment triplexes, limit switches, positioners, control boxes, etc., to achieve local control and remote centralized control. The valve can be switched on and off in the control room, without the need to go to the site or to high altitudes and dangerous places for manual control, which saves human resources and time to a great extent and improves safety.

[0003] However, the current pneumatic ball valve has some shortcomings. The ball valve is mainly controlled by the rotation of the internal ball core. A through hole is opened inside the ball core, so that the pipes at both ends of the valve body can be connected. As time goes by, dirt will form on the inner surface of the through hole inside the ball core. This dirt cannot be easily cleaned and the ball valve needs to be disassembled for cleaning, which is more troublesome. Utility Model Content

A threaded hole 505 is provided on the surface of the support block 501 and in the middle. Guide holes 506 are provided on the surfaces of the support block 501 and the water-permeable mesh ring 503 near the top and bottom. The cooperation of the guide hole 506 and the guide rod 303 can assist the cleaning member 5 to move smoothly; a connecting rod 502 is fixedly installed on the rear surface of the support block 501 and between the threaded hole 505 and the guide hole 506. A water-permeable mesh ring 503 is fixedly installed on the rear surface of the connecting rod 502. The surface of the water net ring 503 is fixedly sleeved with a scraping ring 504. When the scraping ring 504 moves to the ball core channel inside the valve body 1, the ball core channel can be scraped; a water inlet 301 is fixedly installed on the upper surface of one end of the tube body 3, and a water outlet 302 is fixedly installed on the lower surface of one end of the tube body 3. A guide rod 303 is fixedly installed on the inner surface of one end of the tube body 3 near the top and bottom; one end of the threaded rod 6 passes through the tube body 3 and extends into the No. 2 connector 102, the threaded rod 6 passes through the threaded hole 505 and the permeable net ring 503, the inner diameter of the permeable net ring 503 is larger than the diameter of the threaded rod 6, the guide rod 303 passes through the guide hole 506, and the rotating threaded rod 6 can control the movement of the cleaning part 5; one end of the guide rod 303 extends into the No. 2 connector 102.

[0022] It should be noted that the utility model is a low-noise pneumatic ball valve. During use, when the pneumatic ball valve is in a closed state, the ball core of the ball valve is in a connected state with the No. 2 connector 102. The motor 4 is started by an external device, and the motor 4 controls the threaded rod 6 to rotate forward and reverse. The rotating threaded rod 6 causes the cleaning member 5 to reciprocate. When the cleaning member 5 is moving, the scraping ring 504 of the cleaning member 5 can be used to scrape the opening of the ball core. In this way, there is no need to disassemble the pneumatic ball valve to clean the ball core. When the pneumatic ball valve is opened, the external device injects water into the interior of the tube body 3 through the water inlet 301. In this way, the tube body 3 and the cleaning member 5 inside the tube body 3 can be flushed with flowing water. The flushing process discharges the cleaned water from the water outlet 302. After multiple flushing, the cleaning member 5 can be cleaned after use, which is convenient for next use.
