DOUBLE ACTION FLOAT VALVE

摘要

The double action float valve is connected to a single pipe and a tank and controls both the filling and discharge of the tank. The double action float valve utilizes a valve body, a heavy filling obturator positioned within the valve body, a light inverse obturator positioned within the heavy filling obturator, and a float connected to the heavy filling obturator. When the inflow pressure from the pipe is greater than the outflow pressure of the tank, the tank is filled until the float reaches a predetermined level. When the outflow pressure of the tank is greater than the inflow pressure, the double action float valve is automatically reconfigured to discharge the fluid from the tank into the pipe.

1. A float valve comprising:
a valve body defining a valve cavity having a first opening allowing fluid communication between a fluid inlet and said valve cavity and a second opening allowing fluid communication between the interior of a tank capable of storing a fluid and said valve cavity; a first obturator having a density greater than the density of said fluid, positioned within said valve body; said first obturator having a first opening; a second obturator having a density which is less than said density of said fluid; and a float connected to said first obturator.
