Principle and Structure

The principle of storm valve is based on hydrostatic and dynamic principles, through the opening and closing of the control valve to control the water flow, and play a role in preventing the backflow of seawater.

The storm valve is mainly composed of control valve, float, seal ring, bracket and other components. Among them, the control valve is the core component of the storm valve, which is usually divided into two kinds of large and small, respectively installed in the pipeline and pumping station. Valve through the buoyancy of the floating ball, control valve switch. When the seawater rises, the float rises with it and the valve closes, preventing seawater from backing up; when the seawater ebbs, the float drops and the valve opens, allowing the water inside to flow out.
