O-pneumatic cut off the ball SUMMARY
Pneumatic O type cut off the ball pneumatic actuator using the new AT / GT Series pneumatic actuators, the structure of the State utility model patents, double-acting and single-acting (spring return), the gear rack structure Transmission, more secure and reliable performance. 
 
First, the pneumatic O-cut off the ball valve Introduction
 Pneumatic O-cut off pneumatic valve pneumatic actuator using the new AT / GT series of pneumatic actuators, the structure of the state utility model patents, a double-acting and single-acting (spring reset), the use of rack and pinion Structural transmission, more secure and reliable performance; large-diameter valve with AW series of pneumatic actuators, fork structure transmission, reasonable structure, large output torque. 
 Pneumatic O-cut ball valve with a second shut off the ball valve, with explosion-proof device, available gas cut off. It is composed of ball valve and single acting piston pneumatic actuator. It is widely used in industries such as natural gas, oil, chemical, metallurgy, paper-making, mining, printing and dyeing, biopharmaceutical, daily chemicals, food and beverage, water treatment and air treatment Fluid cut off control, and supporting the use of automated pneumatic instruments. 
 
Second, the pneumatic O-cut off the ball valve works
 Pneumatic O-cut ball valve by the body, ball, valve shaft, seal ring, packing, platen and other components. Actuators from the gas, piston, gear type, output shaft, cylinder head, bearings, guide ring, piston bush, adjusting bolts, "O" ring and other major components. Actuator and valve connection shaft. Cylinder input pressure, the role of the piston to produce a certain thrust, the gear-type output driven by the piston, the gear output shaft in rotation, driven by the rotation of the valve shaft, so that the valve ball with the rotation of the valve, change the valve Flow area, to achieve the purpose of changing the medium flow through the valve. 
 
Third, the pneumatic O-cut ball valve Features
 1, thrust bearing to reduce stem friction torque, stem long-term operation can be smooth and flexible. 
 2, seat sealing performance, using PTFE and other elastic materials made of seals.
 3, anti-static function: In the sphere, the valve stem, the spring between the body, the process can switch the static electricity derived. 
 4, the stem seal is reliable, as the stem only for rotational movement without lifting movements, stem packing seal is not easy to damage. 
 5, due to PTFE and other materials with good self-lubricating, and friction loss of the ball is small, so the long service life of the ball valve. 
 6, cut off fast, with one second cut off capacity, and good sealing performance, explosion-proof device can be equipped with gas pipe can be cut off.
