The invention titled Closed pressure vessel with a movable lenticular diaphragm and automatic air release function relates to the field of fluid mechanics and hydraulic engineering, particularly to systems used for water supply and pressure stabilization. The invention introduces a new generation of pressurized tanks that maintain a long-term balance between air and water without the need for frequent manual air bleeding. The system consists of a sealed cylindrical vessel containing a hollow lens-shaped diaphragm that floats on the water surface and moves vertically as the pressure changes. This lenticular diaphragm maintains approximately ninety-nine percent separation between the air chamber above and the water chamber below, which minimizes air absorption into water and prevents the gradual loss of air volume. A perforated circular plate connected to the diaphragm by a stainless steel rod supports the floating structure and stabilizes its horizontal position during operation. The perforated plate also reduces turbulence and equalizes the water flow within the tank, ensuring smooth operation and better air retention. Automatic air management is achieved through upper and lower solenoid valves controlled by an intelligent electrical panel. The panel receives signals from water level sensors and executes a timed sequence that drains, vents, refills, and rebalances the tank automatically. A suction side solenoid valve prevents dry running of the pump, while a pressure switch regulates pump operation based on system demand. The invention eliminates the problems of frequent air loss, unstable pressure, and excessive pump cycling common in conventional systems. It provides consistent water pressure, reduces water wastage, extends equipment lifespan, and allows fully automatic operation without human supervision. This design combines mechanical reliability with intelligent control, offering a durable and efficient solution for modern water supply systems
