Check Valve Definition - China

What Is a Check Valve? Check valves are usually installed in the pipeline to prevent backflow.

A check valve is basically a one-way valve in which the flow can flow freely in one direction, but if the flow turns, the valve will be closed to protect the piping, other valves, pumps, etc.

If the flow is diverted without a check valve installed, a water hammer may occur.

Water hammer often occurs with extreme force and can easily damage pipes or components.

Check Valve Definition A check valve is a fundamental component in fluid systems, playing a crucial role in regulating the flow of liquids or gases.

This simple yet essential device prevents backflow and maintains the desired direction of fluid movement.

Understanding the function and types of check valves is essential for engineers, manufacturers, and anyone involved in fluid control systems.

How Does a Check Valve Work? Check valves operate on a straightforward principle: allowing fluid to flow in one direction while preventing reverse flow.

The valve consists of a movable mechanism, often a disk or a flap, and a body with an inlet and an outlet.

When the fluid flows in the intended direction, the mechanism opens, enabling the fluid to pass through.

However, when there is a reversal in flow, the mechanism closes, preventing the fluid from going backward.
