High performance Rack and Pinion Pneumatic Actuator AT-DA140 Double Action

► Basic composition

The type and structure of the adjustment mechanism of the pneumatic actuator are roughly the same, but the main difference is the actuator. Therefore, when the pneumatic actuator is introduced, it is divided into two parts: the actuator and the regulating valve. Pneumatic actuator consists of two parts: actuator and regulating valve (regulating mechanism). According to the size of the control signal, the corresponding thrust is generated to push the regulating valve to act. The regulating valve is the regulating part of the pneumatic actuator. Under the action of the thrust of the actuator, the regulating valve produces a certain displacement or rotation angle to directly regulate the flow of the fluid.

1. Pneumatic devices are mainly composed of cylinders, pistons, gear shafts, end caps, seals, screws, etc. The complete set of pneumatic devices should also include opening indication, travel limit, solenoid valve, positioner, pneumatic components, manual mechanism, signal Feedback and other components.

2. The connection size of the pneumatic device and the valve shall comply with the regulations of ISO5211 (bottom), GB/T12222 and GB/T12223.

3. The pneumatic device with manual mechanism should be able to use its manual mechanism to open and close the pneumatic ball valve when the air source is interrupted. When facing the handwheel, the handwheel or handle should be rotated counterclockwise to open the valve, and clockwise to open the valve. valve closed.

4. When the end of the piston rod has internal and external threads, there should be a wrench opening suitable for standard wrenches.

5. The sealing ring of the piston should be easy to replace and repair.

6. For the pneumatic device with buffer mechanism, the stroke length of the buffer mechanism can refer to the regulations in Table 1.

7. The pneumatic device with adjustable buffer mechanism should have a mechanism outside the cylinder to adjust its buffer function.

8. The thread size of the air inlet and outlet of the cylinder shall comply with the provisions of MANUR NORM (accessory standard) sypv, GB/T7306.1, GB/T7306.2 and GB/T7307.
