What Is a Precision Regulator?
A precision regulator is a type of regulator that sets pressure with high accuracy. It is used in pneumatic equipment handling compressed air and is known for its superior repeatability compared to typical regulators. Precision regulators can achieve repeatability of about 0.5% of the full span, with ultra-precision models reaching even 0.1% or less.
Applications of Precision Regulators
These regulators are essential in precisely controlling pneumatic actuators like air cylinders. They are used in various applications, including tension control in printing and plastic film machines, pressure control in polishing machines and cutters, and controlling the delivery volume of chemicals or samples. Like general regulators, they are often equipped with air filters and mist separators.
Principle of Precision Regulator
The adjustment of a precision regulator involves an adjustment knob connected to the pressure regulator spring. By turning the knob, the spring’s holding force is set, allowing for precise pressure control on both primary and secondary sides, with or without a relief valve.
Structure of Precision Regulator
Key components include a valve dividing the primary and secondary sides, a regulating spring connected to the valve, and a relief valve on the secondary side. It also incorporates various types of diaphragms for different functions, aiding in the precise control of air pressure.
Other Information on Precision Regulators
1. Role of the Relief Valve
The relief valve in a precision regulator opens automatically to release excess pressure, ensuring safety and preventing potential accidents from overpressure.
2. Role of the Diaphragm
The diaphragm mechanism in precision regulators allows for sharp detection of pressure deviations and precise regulation of pressure. This intricate balance ensures accurate control and efficient operation of the system.
