The check valve is a special valve whose main function is to prevent fluid from flowing back and has good air-tight performance. Introduce the function and working principle of check valve.

1. The function of check valve

1. Prevent fluid from flowing back

The main function of the check valve is to prevent fluid from flowing back and prevent fluid from entering the pipeline where it should not enter. Check valves are very common in normal pressure pipeline networks. They can prevent excessive pressure from causing the fluid in the pipeline to flow back, thus avoiding equipment damage.

2.Has good air-tight performance

The check valve has good sealing performance and can prevent compressed air from escaping, making the system more economical and safer. Check valves are also used to keep out impurities and other fluids and keep the system balanced.
