In almost all industrial production scenarios, valves are a very important class of equipment, mainly used to regulate and control the pressure, flow and flow of the fluid. The nitrogen seal valve is a special valve, its working principle is different from the traditional valve. Below we will detail the working principle of the nitrogen seal valve and its advantages.

1. the definition and structure of nitrogen sealed valve

nitrogen sealed valve is a kind of sealed by nitrogen valve, its structure mainly includes nitrogen sealed chamber, valve body, valve cover, valve and nitrogen inlet. In the nitrogen sealed chamber, nitrogen is injected to form a closed space with the valve stem. When the valve is closed, the nitrogen sealing system is controlled by nitrogen pressure measurement to maintain air tightness. The working principle of

2. nitrogen seal valve

nitrogen seal valve mainly uses compressed air or nitrogen and other inert gases to seal. When the medium enters the valve, it will inject inert gas into the sealing chamber through the sealing system to form a protective layer. When the valve is closed, the sealing system will remain hermetically closed. Therefore, the nitrogen seal valve can effectively avoid the possibility of leakage of liquid or gas medium, avoid man-made injuries and industrial accidents, and improve the safety and reliability of industrial production.
advantages of

3. nitrogen seal valve
compared with traditional valves, nitrogen seal valve has the following advantages:

1. zero leakage: the use of nitrogen to seal, with high sealing performance, to avoid the leakage of media caused by environmental pollution and safety accidents, to ensure the safe operation of industrial equipment.

2. Corrosion resistance: The nitrogen seal valve is made of corrosion-resistant materials and has good adaptability to a variety of media.

3. High temperature and high pressure resistance: The nitrogen seal valve can withstand high temperature and high pressure environment, prevent medium leakage and system failure, and ensure work efficiency and quality.

4. Low maintenance cost: The sealing system of the nitrogen seal valve uses inert gas, which can operate for a long time, and its maintenance cost is relatively low.

Conclusion: The working principle and advantages of

nitrogen seal valve have been widely recognized and applied in industrial applications. With the development of industrial production technology, the application field of nitrogen seal valve will continue to expand, we believe that nitrogen seal valve will better serve the cause of industrial production and environmental protection.
