Different Types Of Ball Valve In Detail

Oct 11, 2017

Ball valve and plug valve is the same type of valve, its closure is a sphere, the ball around the center of the valve body for rotation to open, close a valve. Ball valves are mainly used in piping to cut, distribute and change the flow direction of the media. Ball valve is widely used in recent years, a new type of valve, it has the following advantages: fluid resistance is small, the resistance coefficient and the same length of the pipe section equal. Simple structure, small size, light weight.Ball Valve Close and reliable, the current ball valve sealing material widely used plastic, good sealing, in the vacuum system has also been widely used. Easy to operate, open and close quickly, from full open to full clearance as long as the rotation 90 °, easy to remote control. Easy maintenance, ball valve structure is simple, the seals are generally active, demolition and replacement are more convenient. When fully open or fully closed, the ball and valve seat sealing surface and the media isolation, the media through, will not cause the valve sealing surface erosion. Applicable to a wide range of diameter from small to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.Ball Valve Ball valve has been widely used in petroleum, chemical, power generation, paper, atomic energy, aviation, rockets and other departments, as well as people's daily lives. Ball of the ball is fixed, after the pressure does not produce movement. Fixed ball valve with a floating seat, by the media pressure, the valve seat movement, so that the seal on the ball to ensure that the seal. Usually with the ball on the lower shaft with bearings, operating torque is small, suitable for high pressure and large diameter valves.Ball Valve

In order to reduce the operating torque of the ball valve and increase the reliability of the seal, in recent years there have been oil seal ball valve, both in the sealing surface between the injection of special lubricants to form a layer of oil film, which enhances the seal, but also reduces the operating torque, More suitable for high-pressure large diameter ball valve.Ball Valve
