Type of valve pneumatic pipe essential device

the pneumatic valve is to control the flow of fluid flow, flow, pressure, temperature and so on machinery, pneumatic valve in the pipe system is the basic components. Pneumatic valve pipe fittings in technology and pump, often discussed as a separate category. So what are the types of pneumatic valves? Together we come to understand.
the current international and domestic the most commonly used pneumatic valve classification method has the following kinds:
one, according to the structure characteristics, according to close a pneumatic seat relative to the moving direction can be divided into:
, door, close a moving along the pneumatic valve seat center.
, gate: closing parts along the vertical pneumatic seat center move.
, cock and ball: close is a plunger or a ball, the center line of rotation around itself.
, swing; Close a revolve around pneumatic seat outside of the shaft.

and dish: close a disc, pneumatic seat around the axis of rotation.
shape, smooth pneumatic valve: shut down a slide in the perpendicular to the direction of the channel. Electric: with the help of a motor or other electric device to drive. Hydraulic: with the help of ( Water, oil) To drive. Pneumatic; With the help of compressed air to drive the pneumatic valve opening and closing. Manual: the hand wheel, handle, lever or sprocket, human power, large transmission torque, with a worm gear, gear speed reducer, etc.
3, according to the purpose, according to the different USES of pneumatic valve can be divided into:
and open circuit use: used to connect or cut off the pipeline medium, such as by pneumatic pneumatic valve, ball valve, gate valve, pneumatic butterfly valve, etc.
and reuse: used to prevent the backflow medium, such as check pneumatic valve.
and adjusting use: used to adjust the pressure and flow of the medium, such as adjusting the pneumatic valve, pneumatic valve to relieve stress.
, distribution, use: used to the flow direction of medium change, distribution medium, such as the three-way cock, distribution, pneumatic valve, pneumatic valve, etc.
pneumatic valve, safety: in the medium pressure is more than a specified value, used to discharge redundant medium, to ensure the safety of pipeline systems and equipment, such as security pneumatic valve, pneumatic valve accident.
and other special purposes, such as hydrophobic pneumatic valve, object completely dynamic valve, sewage, pneumatic valve, etc.
