Stainless Steel Threaded Vent Valve
Product Description
Product Overview
The innovative stainless steel threaded air vent valve is meticulously engineered to automatically expel trapped air or gas from liquid-conveying pipeline systems, such as those carrying water or oil. By effectively eliminating air pockets, it mitigates the risk of airlocks, ensures seamless system operation, boosts fluid transfer efficiency, and significantly extends the service life of equipment, making it an indispensable component in industrial settings.
Product Structure
1. Materials
- Valve Body/Cover: Crafted from 304/316 stainless steel, providing exceptional resistance to corrosion and high-temperature endurance, making it ideal for the most demanding environments.
- Internal Components: Features a durable float ball made from stainless steel or a corrosion-resistant composite, accompanied by a robust valve stem and sealing rings composed of EPDM/NBR fluororubber.
- Connection Type: Available with a threaded connection, compatible with G pipe thread or NPT standards, ensuring versatility and ease of integration into existing systems.
2. Design Features
- The compact structure is perfect for installations in areas with limited space, offering flexibility without compromising performance.
- Equipped with an automatic opening/closing mechanism that responds swiftly, eliminating the need for manual operation and enhancing reliability.
- Incorporates a dual-seal design to efficiently prevent any leakage during the gas discharge process.
Working Principle
When gas accumulates within the pipeline, the liquid level inside the valve chamber decreases, prompting the float ball to lower and open the vent port through the valve stem. Once the gas is expelled, the chamber refills with liquid, causing the float ball to rise and securely close the vent port, thereby preventing any liquid leakage.
Applications
- HVAC Systems: Essential for heating pipelines and air conditioning water circulation systems, ensuring optimal performance and energy efficiency.
- Water Supply/Drainage: Vital for high-rise building water networks and firefighting pipelines, providing reliability and safety.
- Industrial Equipment: Ideal for boiler systems, heat exchangers, and solar thermal circulation, enhancing operational efficiency.
- Others: Suitable for hydraulic systems and chemical liquid transfer pipelines, offering versatility across various industrial applications.
