What Are The Installation Requirements For Swing Type Fluorine Lined Check Valves?

What are the installation requirements for Lined Check Valve? Swing check valve is a type of fluorine check valve. Its main function is to control one-way backflow. It is often installed at the outlet of important equipment such as pumps to prevent the medium from backflowing and damaging the equipment. The valve disc of the swing check valve rotates around the rotating shaft. The flow resistance is smaller than that of the lifting check valve. It is more suitable for larger diameter occasions and the installation position is not restricted.

Swing check valves can be divided into three types according to the number of valve discs: single-disc swing type, double-disc swing type and multi-disc swing type. Single-disc swing check valves are usually used in medium-caliber occasions. If used in large-diameter pipelines, in order to reduce water hammer pressure, slow-closing check valves that can eliminate water hammer pressure can be used. Double-disc swing check valves are often used in large-diameter pipelines. The double-disc swing check valve is small in size and light in weight, and is a faster check valve. Multi-flap swing check valve, like double-flap swing check valve, is suitable for large-diameter pipelines.
