Regulator Operating Procedures

Regulator Operating Procedures

Purpose

A regulator is a critical device used to control the pressure of gases or liquids, widely applied in industrial production and laboratory environments. This procedure aims to standardize the operation of regulators to ensure safety, accuracy, and efficiency.

Pre-Operation Preparation

• Confirm that operators have received appropriate training and are familiar with the basic principles and operational procedures of the regulator.
• Inspect the regulator’s exterior for any damage or leakage.
• Check that the pressure gauge and flowmeter are clear, readable, and properly calibrated.
• Verify that all connecting pipelines are secure and free from looseness or gas/liquid leaks.

Operating Procedures

• Open the regulator’s inlet valve to ensure the inlet line is unobstructed.
• Slowly open the outlet valve and observe changes in the pressure gauge reading.
• Gradually adjust the regulating valve according to requirements until the desired pressure is achieved.
• Continuously monitor the pressure gauge and flowmeter during adjustment to ensure pressure and flow remain within acceptable limits.
• After adjustment, close the outlet valve to stop the output of gas or liquid.
• Close the inlet valve to cut off the supply of gas or liquid.
• Clean the external surface of the regulator and return it to its designated storage location.

Safety Precautions

• Operators must wear appropriate personal protective equipment (PPE), including safety goggles, gloves, and protective clothing.
• Never place fingers, body parts, or objects near the outlet to avoid injury.
• If any abnormalities occur (e.g., sudden pressure changes, leaks), immediately stop operation and notify responsible personnel for inspection and repair.
• Never operate beyond the regulator’s rated pressure range to prevent equipment damage or safety incidents.
• After operation, promptly close the inlet valve and cut off the supply to prevent accidental release.

Operation Records

The following information must be recorded for each operation:

• Operator’s name and employee ID;
• Date and time of operation;
• Regulator model and serial number;
• Inlet and outlet pressure values;
• Any abnormalities observed and corresponding corrective actions taken.

Maintenance and Care

• Regularly inspect the regulator’s exterior and connecting pipelines; repair or replace promptly if damage or leakage is found.
• Periodically calibrate the pressure gauge and flowmeter to ensure measurement accuracy.
• Clean both internal and external surfaces of the regulator regularly to maintain proper operation.
• When replacing components, use only original manufacturer parts and follow specified procedures.

Emergency Response

In the event of an emergency (e.g., regulator failure, severe leakage), operators must immediately:

• Shut off the inlet valve quickly to cut off the media supply.
• Evacuate nearby personnel to a safe area and notify responsible personnel for handling.
• Use appropriate fire extinguishing equipment if necessary, and ensure evacuation routes remain clear.
