VALVE FOR OPENING AND CLOSING THE PASSAGE USING BUOYANCY

摘要

PURPOSE: A valve capable of opening and closing by buoyancy is provided to reduce costs by removing additional water leakage sensor because a valve is opened and closed by buoyancy of leaked water. CONSTITUTION: A valve comprises a buoyant member(110). The buoyant member rises as water is filled. A flow channel flowed in and out of raw water is opened and closed by the buoyancy of the buoyant member. An opening and closing member(120) is installed in the buoyant member in order to move together according to moving the buoyant member. The opening and closing member opens and closes the flow channel according to closed with an inlet formed in the flow channel.
