This float-operated condensate valve controls drainage and pressure isolation inside a water cup by combining a buoyant float, a spring-loaded piston, and a dedicated drain passage. How it works: - When there is no pressure inside the water cup, the float seals the inner cavity and the spring pushes the piston downward so that condensate is discharged through drain hole 2. - When pressure inside the water cup rises above 1 kgf/cm2, the piston overcomes the spring force and moves upward, closing the drain hole and isolating the inside of the water cup from the outside environment. - When condensate collects and the float rises due to buoyancy, the float opens the inner cavity, pressure enters the inner cavity, and the piston is then pushed down by pressure and the spring so that condensate is released through the drain pipe. Key benefits: - Automatic and reliable drainage avoids manual emptying by activating only when condensate is present. - Positive pressure isolation prevents unintended leakage or external contamination when internal pressure exceeds 1 kgf/cm2. - Simple mechanical design with float, piston, and spring provides repeatable operation without electronic controls. - Clear, deterministic behavior in three distinct operating states reduces the risk of trapped condensate or false drainage events. Main attributes: - Function is float-controlled automatic drainage with pressure-responsive sealing. - Pressure threshold for sealing is above 1 kgf/cm2. - Core components are a float, an inner hollow cavity, a spring-loaded piston, drain hole 2, and a drain pipe. - Intended for installation inside a water cup or condensate collection vessel. Typical applications: - Drainage control for air conditioning condensate cups and drip pans where automatic condensate removal is required. - Condensate management in refrigeration and dehumidifier collection vessels to prevent overflow and maintain system operation. - Use in HVAC or industrial condensate collection systems where pressure isolation is needed during pressurized conditions. This valve provides a straightforward mechanical solution for controlled condensate discharge and reliable pressure isolation during normal operation.
