Wuxi Xinming automatic control valve industry co., ltd. and you to understand the origin of pneumatic ball valve Pneumatic ball valve is a ball valve with pneumatic actuators, and pneumatic ball valve is evolved from the globe valve. The lifting action has the same rotation of 90 degrees, except that the cock body is a sphere, which has a passage through hole or round through its axis. The ratio of the spherical surface to the channel opening should be such that when the ball rotates 90 degrees, the spherical surface should appear at the inlet and outlet, thus cutting off its flow. The working principle of the pneumatic ball valve is to rely on the rotary valve so that the valve is blocked or dredged. The pneumatic ball valve switch is light and small in size, which can be made into a large caliber, simple in structure, reliable in sealing, and convenient in maintenance. The sealing surface and the spherical surface are often in a closed state and are not easily eroded by the medium, so it can be used in various industries. Widely used. Pneumatic ball valves are now widely used in petroleum, chemical, power generation, papermaking, atomic energy, aviation, rockets and other departments, as well as in people's daily lives. Pneumatic ball valve and plug valve is a type of valve, but its closure is a sphere, the sphere around the center line of the valve body to rotate to reach the closed, open a valve. Quick and convenient 1. switch can meet the requirements of quick opening and quick closing of high-altitude tunnel for pipeline 2. the fluid resistance is small, so whether it is full-bore type reduced diameter ball valve is a smaller fluid resistance in all valves. 3. firm valve seat seal, general ball sealing ring are made of tetrafluoroethylene type other polymer materials with better plasticity. where there are higher requirements for sealing, soft sealing is easier to ensure sealing. metal sealing, <hard seal> structure can withstand high pressures of 10Npa, 16Npa and 32Npa at 350 ℃ in daily life. 4. solid valve stem seal, stem reverse sealing structure can be larger with the progress of the medium, valve stem valve opening and closing only for rotation movement, and do not do lifting movement. The sealing packing of the valve stem is not easily damaged. The sealing life of the valve stem is greatly extended. 5. of the long service life, the pneumatic device is more than 60000 in the damage test. Because the sealing part of the ball valve is mostly made of polytetrafluoroethylene with good self-lubricating properties, such as polytetrafluoroethylene, which is made of less conflict and wear with the ball valve and the valve stem, ensuring the service life of the valve. The above is the origin of the pneumatic ball valve shared by Wuxi Xinming automatic control valve industry co., ltd. and you.

Pneumatic ball valveIs the ball valve with a pneumatic actuator, while the pneumatic ball valve is evolved from the globe valve. The lifting action has the same rotation of 90 degrees, except that the cock body is a sphere, which has a passage through hole or round through its axis. The ratio of the spherical surface to the channel opening should be such that when the ball rotates 90 degrees, the spherical surface should appear at the inlet and outlet, thus cutting off its flow.

The working principle of the pneumatic ball valve is to rely on the rotary valve so that the valve is blocked or dredged. The pneumatic ball valve switch is light and small in size, which can be made into a large caliber, simple in structure, reliable in sealing, and convenient in maintenance.
