"Case Study: Application Example of German Standard Bellows Globe Valve under Special Working Conditions"

The German standard bellows globe valve has a wide range of applications in various special working conditions due to its unique structure and performance. This article will explore the application of German standard bellows globe valves under special working conditions through a specific case, and analyze the key factors in their design and application process.

Case background:

In a corrosive medium transportation system of a certain chemical enterprise, a German standard corrugated pipe globe valve is required to control the flow of corrosive medium. The medium under this working condition has strong corrosiveness, high pressure, and high temperature characteristics, with a temperature of up to 200 ° C and a pressure of up to 100MPa. This poses high requirements for the design and material of the valve.

1、 Design points

1. Material selection: Considering the characteristics of strong corrosion, high pressure, and high temperature working conditions, a German standard corrugated pipe globe valve made of alloy stainless steel material was selected. This material can maintain good mechanical properties at high temperatures and has high resistance to corrosive media.
2. Bellows design: In order to withstand high pressure and temperature changes, the bellows adopts a special design, increasing the density of peaks and valleys, and improving the strength and stability of the bellows.
3. Sealing design: Adopting a double-layer sealing structure, the inner layer is soft sealed and the outer layer is hard sealed, ensuring zero leakage under extreme working conditions.
4. Cooling system: As the valve operates at high temperatures, a cooling system has been added to the design to reduce the internal temperature of the valve and ensure its normal operation.

2、 Application effect

1. Safety: After installation, the German standard corrugated pipe globe valve has successfully passed the manufacturer's testing and on-site testing, ensuring safe operation under special working conditions.
2. Reliability: The valve has demonstrated good stability during operation, without any leakage or other faults, ensuring the continuity of the process flow.
3. Corrosion resistance: Due to the selection of suitable materials, the valve exhibits good corrosion resistance when facing corrosive media, extending the service life of the valve.

The application of German standard bellows globe valves under special working conditions requires comprehensive consideration of multiple factors such as material selection, structural design, sealing design, and cooling system. Through the study of this case, we can see that through precise design and material selection, the German standard corrugated pipe globe valve can provide a safe, reliable, and efficient solution under extreme working conditions. This has important reference value for industrial applications under similar special working conditions.
