Abstract

A float valve for a chemical reactor has a central pipe which glides around a liquid transfer pipe when a liquid level rises and falls, thereby opening for fluid transfer through liquid transfer apertures in the transfer pipe when the liquid level is rising and shutting off for fluid transfer when the float lowers and seals against a sealing ring placed on the transfer pipe below the liquid transfer apertures.
