Pneumatic type O pneumatic valve related parameters and application scope

Pneumatic valve pneumatic type O is the jacket type structure of the pneumatic valve, under the condition of high pressure, large diameter reduced the connecting bolts of pneumatic valve body itself, to strengthen the security of the pneumatic valve and restrained system weight affect pneumatic valve normal work.



principle: pneumatic type O, pneumatic valve, pneumatic valve by pneumatic valve body, body axis and seal ring, filler, linking piece parts. By gas, piston and gear actuator type, output shaft, bearing, cylinder head, adjust the bolt guide ring, piston bush, and 'O' type circle and other major parts. Actuators and pneumatic valve shaft cohesion. After the input air pressure in the cylinder, produce certain thrust acting on the piston, the gear type output under the piston propulsion, make gear output shaft to rotate, drives the pneumatic valve shaft rotation, so that the pneumatic valve in the pneumatic valve with rotation, the change of the circulation area of the pneumatic valve, to change after pneumatic valve within the medium flow.

64 or other standard type of flange according to user's request matching ( Such as ANSI, JIS, DIN and other standards)



pneumatic type o the characteristics of pneumatic valve
1, o floating pneumatic valve adopts full size or reducing design, small flow resistance.
2 high platform structure, pneumatic valve, with ISO5211 standard, can make the device electric/pneumatic actuator is more professional.
3, pneumatic valve rod with built-in type, shoulder and polytetrafluoroethylene ( Or reinforced graphite) Thrust pad structure to avoid pneumatic valve stem blow out because of the pressure in the pipeline, and ptfe ( Or reinforced graphite) Data reduce pneumatic valve opening and closing torque, make the operation more efficient.
4, have fire retardant anti-static structure, in the pneumatic valve stem and valve body and pneumatic valve stem and body set up between the conductive spring, prevent due to electrostatic spark to ignite flammable medium. To ensure the system safe.
5, fire-proof structure dual maintenance, when fire one thousand attacks and make the seal loss, all sealing parts of pneumatic valve can constitute a metal to metal hard seal structure.

pneumatic type O pneumatic valve is widely used in chemical, petrochemical, rubber, paper, pharmaceutical, etc. As a medium in the pipeline flow diverting rivers or switch device.
