Beschreibung
Zusammenfassung:	The invention discloses a constant-flow drain valve which comprises a water valve cavity, a water valve water inlet connector, a filter screen, a water valve drain connector, a water valve liquid outlet, a valve pipe, a valve column, a plunger valve and a floating ball. The water valve water inlet connector is arranged at the upper end of the water valve cavity, the filter screen is arranged in the water valve water inlet connector, the water valve drain connector is arranged at the lower end of the water valve cavity, the water valve liquid outlet is formed in the water valve drain connector, the valve pipe is arranged on the water valve liquid outlet, the valve column movably penetrates into the center of the valve pipe, the plunger valve is arranged at the top of the valve column, and the floating ball is arranged on the plunger valve. The plunger valve is lifted directly through the buoyancy of the floating ball, the buoyancy of the floating ball and opening of the plunger valve are in direct proportion,
