What Is Air Pressure Regulators?
Air Pressure Regulators are devices used to reduce the pressure of compressed air created by air compressors from high to low pressure. The required air pressure is fixed for pneumatic power equipment. However, if you purchase an air compressor to match it, the cost will be very high. To eliminate that, we use air regulators to achieve multiple air pressures with one air compressor.
Air power is useful in places where electricity is difficult to use, such as explosion-proof environments.
Uses of Air Pressure Regulators
Air Pressure Regulators are used when the compressed air pressure obtained from an air compressor is high.
For example, an automatic ball valve uses an actuator to move the valve, and compressed air is sometimes used to power the actuator. At that time, an electric current is passed through the solenoid valve, and compressed air is sent according to the opening and closing of the solenoid valve.
The operating pressure range of the solenoid valve is about 0.3 to 0.7 MPa, and compressed air above 0.7 MPa must be depressurized.
Air Pressure Regulators are also used to operate machines and air blowers.
Principle of Air Pressure Regulators
Air Pressure Regulators can be set in the range of 0.05 to 0.85 MPa.
The pressure is regulated mainly by means of a spring, which is attached to a valve shaped like a globe valve in the middle of the supply route from the primary side to the A spring is attached to this valve (valve spring).
The secondary side also has a spring (regulating spring), and the spring is used to push the regulator from both the primary and secondary sides.
The pressure regulating spring can be adjusted by turning the handle attached to the Air Pressure Regulators. The pressure is adjusted by the balance between the force of the adjustment spring and the force of the secondary pressure with the diaphragm as the boundary. In other words, pushing in the adjusting screw to apply force to the adjusting spring will set the secondary pressure to match that force.
When the secondary pressure is lower than the set pressure, the valve spring is pushed and air flows into the secondary side; when the secondary pressure and the pressure of the regulating spring match, the balance is maintained and the valve section closes.
