Abstract

An automatic water level control device with a float valve using internal pressure, gravity and buoyancy includes a valve body connected to a pipe, a valve inserted into the valve body with a distance, a net provided to an inner periphery of an end of the valve body for filtering impurities which deteriorates the operation of the valve, a spring mounted between the valve and the net for protecting the valve under a low pressure and keeping the precision of valve operations by forcibly pushing the valve when a water level becomes high, a supporting die connected to the valve body for transmitting the gravity of a ball to the valve by leverage to control the valve, and the ball mounted to the supporting die for generating the gravity when the water level becomes lowered so as to open the valve.
