Marine Vertical Type Storm Valve
Marine vertical type storm valve is a crucial component in a ship's drainage and bilge system. Its primary function is to prevent seawater from entering the vessel through the drainage system during rough sea conditions, thereby protecting the vessel's interior spaces from flooding.
Overview
Design and Construction
Vertical Orientation: The valve is installed in a vertical position, which allows for efficient drainage and prevents backflow of seawater.
Material: Typically made from corrosion-resistant materials such as stainless steel or bronze to withstand harsh marine environments.
Non-return Mechanism: Equipped with a non-return flap or disc that automatically closes to prevent the reverse flow of water when external pressure increases.
Working Principle
Normal Operation: Under calm sea conditions, the storm valve remains open, allowing water to drain out from the ship's deck or internal spaces.
Storm Conditions: When waves and external water pressure increase, the valve's non-return mechanism is activated, closing the valve to prevent seawater from entering the ship.
