The oxygen-filling process for liquid oxygen tanks must adhere to specific operational procedures and safety measures. Here are the steps for filling liquid oxygen tanks:
Preparation: Ensure the tanks and oxygen-filling equipment are in good working condition; check the tank's sealing integrity and the proper operation of the safety valves.
Connect equipment: Link the oxygenation equipment to the tank, ensuring the connection is sealed reliably.
Prepare liquid oxygen: Transfer liquid oxygen from the storage container to the oxygen storage tank of the filling equipment. During the transfer, be cautious to avoid any leakage or contact with the liquid oxygen.
Oxygen Filling Operation: Open the valve of the oxygen filling equipment and fill liquid oxygen from the oxygen storage tank into the storage tank. During the filling process, control the filling speed and pressure to avoid excessive tank pressure and temperature rise.
Monitoring and Control: During the aeration process, the tank's pressure and temperature must be monitored to ensure they remain within safe limits. In the event of any abnormalities, aeration should be halted immediately and appropriate actions taken.
Oxygen Filling Completed: Close the valve of the oxygen filling equipment and stop the filling operation once the tank reaches the required oxygen level or pressure.
Safety Handling: After the oxygenation is completed, safety handling is required, including closing relevant valves and emptying any remaining liquid oxygen from the oxygenation equipment.
Note that liquid oxygen is highly oxidizing and flammable; the oxygen-filling process must strictly adhere to relevant safety operation procedures and standards. Operators should receive training and strictly follow the operational procedures and safety measures to ensure the safety and reliability of the oxygen-filling process.

The process of adjusting oxygen supply using liquid oxygen storage tanks generally involves the following steps:
Liquid Oxygen Storage Tank Oxygen Supply System: Typically, a liquid oxygen storage tank oxygen supply system is installed, which includes a liquid oxygen storage tank, liquid oxygen transmission pipeline, and pressure regulating devices, etc. The liquid oxygen in the storage tank is transported through the pipeline to the pressure regulating device.
Pressure Regulator: The pressure regulator is used to convert high-pressure liquid oxygen into the required low-pressure oxygen. It typically includes a pressure control valve, a reducer, and a flow meter. The pressure control valve is used to regulate the pressure of the oxygen, the reducer is used to reduce the pressure of the high-pressure liquid oxygen to the desired low pressure, and the flow meter is used to measure the flow rate of the oxygen.
Oxygen Delivery Pipeline: Low-pressure oxygen exiting the pressure-regulating unit is transported through the delivery pipeline to areas requiring oxygen supply, such as wards and operating rooms. The输送 pipelines are typically made of stainless steel or plastic, offering excellent airtightness and corrosion resistance.
Oxygen Interface: Install oxygen interfaces at locations requiring oxygen supply, such as hospital beds or operating tables. Oxygen interfaces typically include oxygen flow regulators and connectors, used for adjusting oxygen flow and connecting to oxygen masks or tubes.
Oxygen Supply and Regulation: Adjust the pressure and flow of oxygen by controlling the pressure valve of the pressure regulator. Modify the flow and concentration of oxygen according to the patient's needs, ensuring they receive an adequate oxygen supply.
Note that when using liquid oxygen storage tanks for pressure-regulated oxygen supply, it is crucial to adhere to the relevant equipment operation and safety procedures. Operators must have the necessary training and skills to ensure the normal and safe operation of the oxygen supply system. Furthermore, regular inspections and maintenance of the system's equipment and pipelines are essential to ensure their proper functioning and safety.

Proper installation of the safety valve on liquid oxygen tanks is a crucial step to ensure safe operation. Here are the installation steps for the safety valve on liquid oxygen tanks:
Select the appropriate safety valve: Choose a suitable safety valve based on the design pressure and flow requirements of the liquid oxygen storage tank. Ensure that the rated pressure and flow of the safety valve meet the tank's specifications and comply with relevant safety standards and regulations.
Valve Installation Location: Choose a suitable location to install the safety valve. Typically, the safety valve should be mounted on the top or side of the liquid oxygen storage tank to allow for timely pressure release in case of overpressure conditions.
Prepare installation interfaces: Prepare the corresponding interfaces according to the connection method of the safety valve. This may include welding interfaces, threaded interfaces, or flange interfaces, etc. Ensure the sealing and firmness of the connections.
Install the safety valve: Mount the safety valve onto the prepared interface. Follow the installation instructions for the safety valve to ensure proper connection and tightening.
Adjustment and Testing: After installation, adjust and test according to the safety valve specifications. Ensure the opening and closing pressures of the safety valve meet the design requirements, and conduct a leak test to ensure its sealing.
Identification and Record: Mark relevant information on the safety valve, such as rated pressure, flow rate, and installation date. Also, record the installation details and test results of the safety valve for future reference and maintenance.
When installing the liquid oxygen safety valve, it is imperative to follow the relevant safety regulations and operational guidelines. If you lack the necessary experience and knowledge, it is advisable to seek assistance and guidance from a professional to ensure the correct installation and reliable operation of the safety valve.
