Track pneumatic ball valve operating principle

orbit hard seal ball working principle of pneumatic valve: http://www. zgbfw。 The principle of com/info /
CAM make the pneumatic valve ball break with pneumatic valve seat sealing surface in the rotation, pushed pneumatic valve ball spinning in place before the pneumatic valve seat seal. When the pneumatic valve is in full open position, turn the handwheel, instantaneous needle in pneumatic stem nut and cooperated by thrust bearing, pneumatic stem began to drop and drive the ball begin to spin. Connection rotation handwheel, pneumatic valve stem of the precision of spiral curve groove track, interact with embedded in its guide pin, drive the ball with pneumatic stem clockwise rotation. When the pneumatic valve will be closed, pneumatic valve rod drives the ball with the pneumatic valve seat sealing surface completely without friction spinning °. Continue to turn the handwheel, fell again pneumatic valve lever through pneumatic mechanical CAM structure of the bottom of the stem to oppress a sphere, the sphere seal face closely contact with pneumatic valve seat sealing surface, thus achieve the purpose of sealing. Orbital hard seal ball pneumatic valve counterclockwise rotation handwheel when in a seated position, in the pneumatic stem nut and with the cooperation of thrust bearing, pneumatic valve rod began to rise, and drive the ball begin to spin,. Continuous turn the handwheel, the pneumatic valve stem will rising at the same time drive the ball to pneumatic valve seat. Orbital hard seal ball pneumatic valve will open, pneumatic valve stem of the precision of spiral curve groove track interact with embedded in the guide pin drives the ball with the pneumatic valve seat sealing surface completely without friction press anticlockwise turn. Continue to turn the handwheel, when pneumatic valve rod reaches the limit position, the ball has with the pneumatic valve stem reverse °, pneumatic valve is in full open position. http://www。 zgbfw。 Com/info /
track hard seal ball pneumatic valve structural features: the traditional pneumatic ball valve, floating or fixed sphere always contact with the pneumatic valve seat, the switching torque, the sealing surface is easy to damage, track ball on opening and closing, the sphere deflection - first The delta Angle, and then turn, switch sphere with pneumatic seat during the whole process from, so the pneumatic seat will not be scratch, and open-close torque is small. http://www。 zgbfw。 Com/info /
