Directly Buried Fully Welded Ball Valves: An Innovative Solution for Underground Pipeline Networks
With the acceleration of urbanization, the construction and management of underground pipeline networks have become critical issues. The directly buried fully welded ball valve, as a new-generation underground pipeline valve, leads the future development of underground infrastructure with its advanced design and superior performance. This article details its working principle, features, and applications in underground pipeline systems.
I. Working Principle
The directly buried fully welded ball valve is a specialized valve based on a fully welded structure and the operational mechanism of a ball valve. Its key components include the valve body, ball, sealing rings, and actuator.
Opening Process: The actuator rotates the ball away from the valve seat, allowing fluid to flow through the open passage.
Closing Process: The actuator reverses the rotation, realigning the ball with the valve seat to shut off the flow.
II. Key Features
Innovative Design: The valve body is directly welded to the pipeline, significantly enhancing sealing integrity and structural stability.
High Reliability: Its compact and simple structure, combined with metal sealing rings, ensures excellent wear and corrosion resistance.
Ease of Maintenance: The top-entry actuator design simplifies repair and replacement. Additionally, the valve offers strong anti-vibration and explosion-proof performance, making it suitable for harsh underground environments.
Long Service Life: The use of high-quality sealing materials and corrosion-resistant design ensures durable and stable operation in underground conditions.
Space-Saving: The compact construction minimizes space requirements, allowing greater flexibility in pipeline and equipment layout.
III. Applications in Underground Pipeline Systems
Wastewater Treatment Plants: Controls sewage flow direction and volume, preventing leaks and groundwater contamination due to its superior sealing and corrosion resistance.
Stormwater Drainage Systems: Manages rainwater flow and discharge, offering high reliability and longevity for drainage infrastructure.
Water Supply Systems: Regulates water flow and pressure, ensuring system stability and safety with its leak-proof and high-pressure resistance.
Gas Distribution Networks: Safely controls gas flow, making it an ideal choice for gas supply systems due to its durability and leak-tight performance.
Other Industrial Applications: Also used in power generation, chemical processing, and petroleum industries for fluid control.
IV. Conclusion
The directly buried fully welded ball valve is an innovative, reliable, and maintenance-friendly solution for underground pipelines. Its advantages in wastewater treatment, stormwater drainage, water supply, and gas distribution systems enhance efficiency and operational safety. As technology advances, this valve will play an increasingly vital role in shaping the future of underground pipeline networks.
