GB cast steel Trunnion ball valves ：In-depth analysis of structure and features
The national standard cast steel fixed ball valve is a valve equipment widely used in industrial pipeline systems. Its design standards comply with Chinese national standards and have specific structural characteristics and performance advantages. The following is a detailed introduction to the national standard cast steel fixed ball valve:
1. Structural features:
-The main characteristic of a fixed ball valve is that the ball is fixed and cannot move, and the switch is achieved through the movement of the valve seat. This design simplifies the structure of the valve, making operation more stable and reliable.
-The use of cast steel material enhances the pressure resistance and wear resistance of the valve, making it suitable for a wider range of working environments.
2. Main component materials:
-The main component materials of national standard cast steel fixed ball valves include carbon steel, stainless steel, etc. The selection of these materials can be adjusted according to actual working conditions to meet different usage needs.
3. Application areas:
-Due to its excellent performance and reliability, national standard cast steel fixed ball valves are widely used in pipeline systems in industries such as petroleum, chemical, and natural gas to control the flow of media.
4. Execution standards:
-The design, manufacturing, and testing of this ball valve are carried out in accordance with national standards such as GB/T12237, ensuring the quality and performance of the product.
5. Maintenance and upkeep:
-Regularly check the working status of the valve, clean up accumulated impurities in a timely manner, and maintain the cleanliness of the valve.
-For valves that are not used for a long time, regular opening and closing operations should be carried out to prevent the ball from sticking to the valve seat.
In summary, the national standard cast steel fixed ball valve plays an important role in various industrial fields due to its unique structure and superior performance. Understanding its basic characteristics and usage methods can help to better utilize this equipment, improve production efficiency and safety.
