Introduction to Pneumatic Control Components and Auxiliary Components

Introduction of pneumatic control components:

1. Pressure valve

A. Pressure reducing valve: used for pressure reduction cake

B. Booster valve: for booster

2. Flow valve

A. One-way throttle valve: control the movement speed of the cylinder

B. Exhaust throttle valve: installed in the exhaust port of the reversing valve to control the movement speed of the cylinder

C. Quick exhaust valve: It can quickly exhaust pneumatic components and devices

3. Directional valve

A. Solenoid valve, air control valve, human control valve, machine control valve: components that can change the flow direction or on-off of gas. The control methods include electromagnetic control, air pressure control, human control and mechanical control.

B. One-way valve: the airflow can only flow in the forward direction and cannot flow in the reverse direction

C. Shuttle valve: As long as one of the two inlets has input, there will be output.

D. Double pressure valve: when both inlets have input, there is output.

4. Proportional valve: The output pressure (or flow) changes in proportion to the input model (voltage or current).

Introduction of pneumatic auxiliary components:

1. Lubrication element

A. Lubricator: The lubricating oil is atomized and flows into the parts that need to be lubricated with the compressed air.

B. Centralized lubricating element: lubricator for multi-point lubrication. The public account "Mechanical Engineering Literature", the gas station for engineers!

2. Muffler: reduce exhaust noise

3. Exhaust cleaner: reduce exhaust noise, and can separate the oil mist and condensed water contained in the exhaust gas.

4. Gas-liquid converter: used to absorb impact energy and reduce noise.

5. Pneumatic display: a component that is displayed when there is a gas signal.

6. Pressure switch: When the air pressure reaches a certain value, the electrical contacts can be turned on or off. Used to confirm and detect fluid pressure.

7. Pipes and pipe joints: for connecting various pneumatic components

8. Pneumatic sensor: Convert the physical quantity to be measured into a gas signal for the subsequent system to judge and control. It can be used to detect dimensional accuracy, position accuracy, counting, size sorting, deviation correction, liquid level control, and judging presence or absence.

9. Flow switch: It is used to confirm (the flow reaches a certain value, command the on-off of the electrical contact) and detect (instantaneous flow, cumulative flow) the flow of the fluid.
