Ball valve works and advantages (Figure)

The working principle of the ball valve is by rotating the valve to make the valve unblocked or blocked. Ball valve switch is light, small size, can be made of large diameter, reliable sealing, simple structure, easy maintenance, sealing surface and the spherical surface is often closed, easy to be media erosion, widely used in various industries. Ball valve and plug valve are of the same type of valve, and only its closure is a sphere, the sphere around the centerline of the valve body to rotate to achieve open, close a valve. Ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. Ball valve is widely used in recent years, a new type of valve, which has the following advantages: 1. Fluid resistance is small, the resistance coefficient and the same length of the pipe section. 2. Simple structure, small size, light weight. 3. Tight and reliable, the current ball valve sealing surface material widely used plastic, good sealing, vacuum system has also been widely used. 4. Easy to operate, quick opening and closing, as long as 90 ° rotation from full open to full close, easy to remote control. 5. Easy maintenance, ball valve structure is simple, the seals are generally active, demolition and replacement are more convenient. 6. In the fully open or fully closed, the ball and valve seat sealing surface and media isolation, the media will not cause erosion of the valve sealing surface. 7. Wide range of applications, the path from small to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied. Ball valve has been widely used in petroleum, chemical, power generation, papermaking, atomic energy, aviation, rockets and other departments, as well as people's daily lives.
