Pneumatic actuator principle
the pneumatic actuator is a kind of installed on the valve control mechanism, also called a pneumatic head, common electric valves, electric ball valves, electric butterfly valves with pneumatic actuators, pneumatic actuators is automatic control valves open and close, and very quickly.
usually pneumatic actuators are used in piston and crank arm cylinder structure, output torque, small volume. Actuator adopt fully sealed waterproof design protection grade is high. Cylinder block USES the import mirror cylinder, oil free, small friction coefficient, corrosion resistance, with super durability and reliability, all drive bearing adopts boundary self-lubricating bearing without oil lubrication, can't ensure that transmission wear and tear.
pneumatic actuators at work, will work the air from A hole input, on both sides of the air pressure in the cylinder to push the piston to move, counterclockwise, the output shaft to drive valve opening and closing operation.
by compressed air hole type B, pushes the piston in the cylinder to center, counterclockwise, the output shaft to drive valve opening and closing operation. This is the working principle of the pneumatic actuator at work I can see actuators can quickly make the rotation of the cylinders. Below we to pneumatic actuators and a detailed introduction, introduced in the following we will from multiple perspectives.
actuators with
1, compact double piston gear rack mechanism, flexible lightweight double piston connecting rod mechanism, Angle of output.
2, material for the die casting aluminum alloy cylinder body ( Aluminum alloy by hard anodic oxidation wear resistance, corrosion resistance, long life) 。
3, gas source: clean air filter, dry or lubrication, small pressure of 0. 1 MPa, pressure 1 MPa.
4, inner surface of special processing to ensure friction and long life.
5, with low friction materials made of sliding device, to avoid the direct contact of metals and metal.
6, bottom fixed hole for actuators connected to the valve and make it to positive, accords with ISO5211 / DIN3337 standard.
