Description of Flange Swing Check Valve

Flange swing check valve is a device used to prevent the backflow of media in pipelines. The valve disc closes quickly, the water hammer pressure is small, the flow channel is smooth, the fluid resistance is small, the action is sensitive, the sealing performance is good, and the overall structure is simple and compact. Beautiful appearance, long service life and high reliability. These characteristics make the flange swing check valve one of the important safety equipment in industrial pipeline systems.

The main contents of Flange Swing Check Valve inspection

1. Check whether the dynamic seal of the valve stem and the static seal of the flange gasket are leaking;
2. Whether the opening and closing status is normal;
3. Check whether the valve body is damaged or leaking. If the valve is abnormally open or normally closed, rotate it 1 to 2 times or perform a lifting test;
5. Lubricate the valve stem of normally open or normally closed valves;

Advantages of Flange Swing Check Valve

1. Small size, light weight, small fluid resistance, and low water hammer pressure when closed;
2. Easy and flexible operation, long service life;
3. It has good sealing performance, can effectively prevent medium leakage and ensure the stable operation of the system;
4. Simple structure, easy installation, low maintenance cost, high reliability and stability.
