The role of double sleeve gas source ball valve in the transportation process of oil and natural gas
Date: 2025-12-14Read: 10
Double sleeve gas source ball valve is an important control component widely used in gas pipeline systems, usually used in working environments such as gas transportation, flow control, and pressure regulation. It adopts dual sleeve sealing technology, which can provide efficient and reliable sealing performance, and adapt to the application needs in various gas environments.
Double card sleeve gas source ball valveStructural characteristics:
1. Valve body: The valve body is the main load-bearing component of a ball valve, usually made of corrosion-resistant materials such as stainless steel and carbon steel, and can withstand high pressure.
2. Sphere: The sphere is the most critical control component in ball valves, usually made of corrosion-resistant metal materials or alloys, with a smooth surface to ensure smooth fluid flow.
3. Valve seat: The valve seat is in contact with the sphere and is responsible for sealing function. Through the double sleeve sealing structure, the seal between the valve seat and the ball is more tight, avoiding leakage problems.
4. Card sleeve sealing ring: The card sleeve sealing ring is located between the valve body and the valve seat, and usually uses high-performance sealing materials (such as PTFE, PCTFE, NBR, etc.) to maintain good sealing performance under high pressure and high temperature conditions.
5. Valve stem: The valve stem is a component that connects the ball and the valve operating mechanism, playing a role in rotating the ball and usually maintaining a tight connection with the ball to ensure operational sensitivity.
6. Manual or automatic operating mechanism: It can be operated through manual, pneumatic, electric and other methods to meet the needs of different degrees of automation.
Working Principle:
When the valve is in the closed state, the sealing surface between the hole on the sphere and the valve body is fully connected, and gas cannot pass through.
When the valve rotates, the hole of the sphere opens or closes in the direction of the pipeline, and the airflow will pass through the hole on the sphere or be completely cut off.
The function of the double sleeve sealing structure is to ensure a more stable sealing effect between the ball and the valve body, especially in environments with high pressure or corrosive gases, which can still guarantee zero leakage.
Application areas of double sleeve gas source ball valve:
1. Oil and gas industry: During the transportation of oil and gas, it is possible to control the gas flow rate and pressure to ensure the stable operation of the pipeline system.
2. Chemical production: The chemical industry often involves high temperature, high pressure, and corrosive gases, and its sealing performance makes it an ideal choice.
3. Gas and natural gas pipelines: Gas and natural gas pipelines often require the use of gas source ball valves to ensure safe and accurate flow regulation.
4. Air compressor and pneumatic system: In the air compressor and pneumatic control system, the airflow can be effectively regulated to ensure the efficient operation of the system.
5. Medical equipment: Some medical equipment requires precise control of gas flow and pressure, which can provide high safety and stability to ensure the safe use of medical gases.
