It's important to note that the use of liquid oxygen tanks must strictly adhere to relevant safety regulations and operational guidelines to ensure safe operation and usage of the tanks.

The process of using liquid oxygen storage tanks for pressure-regulated oxygen supply typically includes 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 pipelines, and pressure regulating devices. The liquid oxygen in the storage tank is transported through the pipelines 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 valve, a reducer, and a flowmeter. The pressure valve is used to control the oxygen pressure, the reducer is used to reduce the high-pressure liquid oxygen to the required low pressure, and the flowmeter is used to measure the oxygen flow rate.
Oxygen Supply Pipeline: Low-pressure oxygen released from the pressure regulating device is transported through pipelines to areas requiring oxygen supply, such as wards and operating rooms. The 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 an oxygen flow regulator and oxygen connectors, used for adjusting oxygen flow and connecting oxygen masks or tubes.
Oxygen Supply and Regulation: Adjust the pressure and flow of oxygen by manipulating the pressure regulating valve of the pressure regulator. Tailor the flow and concentration of oxygen according to the patient's needs, ensuring an adequate oxygen supply for the patient.
Be mindful that when using liquid oxygen tanks for pressure regulation and oxygen supply, it is crucial to adhere to the equipment usage and safety operation procedures. Operators must possess relevant training and skills to ensure the normal and safe operation of the oxygen supply system. Additionally, conduct regular inspections and maintenance of the system's equipment and pipelines to guarantee their proper functioning and safety.
