Eccentric half ball
Wearable ball for spraying coal, gas control dust, with the best equipment and the powder particles in fluid conveying solid medium, used in metallurgy, mineral processing and production of special valves. Features: Straight, one-way seal, the whole ball-type structure, especially for pulverized coal injection of gas-solid flow medium, unobstructed passage through customs, or stuck fouling phenomenon does not occur. Switch it clear, the starting torque is small, flexible rotation. When closed, the whole ball and seat squeeze cutting action can remove surface dirt seal, seal tight and reliable.
Discharging valve includes a valve body rigidly connected with the bonnet of the valve body mounted in the ball valve, the ball valve body and electrical connection means. Characterized by: fluid resistance, its drag coefficient with the same pipe length equal. Simple structure, small size, light weight, compact, reliable, easy to operate, opening and closing rapidly. From fully open to fully closed as long as the rotation of 90 °, to facilitate remote control. Path from small to a few millimeters to a few meters from the high vacuum to high pressure can be applied. Has been widely used in various sectors of petroleum, chemical, power generation, paper, nuclear, aviation, rockets, as well as people's daily lives.
