Automatic liquid fluid purge system, applicable to centrifugal separators, characterized by being made up of a set of elements mounted inside a receiving tank, where the separated liquid accumulates, and which are integrated by a piece of the racord type that is it joins the cuvette with a fixing nut and packs a second part that acts as a valve of the system, with the particularity that the first part has holes that allow the passage and communication of the liquid with the lower part of the valve, which face the upper part is equipped with a hole, axially practiced, which communicates with a longitudinal recess made along its entire length and by which part of the set of these two pieces is fixed to a static cap which, in turn, is surrounded by a buoy. Cylindrical, with central through hole, which allows its ascending-descending sliding along the aforementioned bushing, which presents its a closed arrangement with a hole, of greater section than the one made in the valve of the device, and a sliding sleeve provided with communication holes that houses a sealing piece inside, which opens and closes the hole that it puts into communication. With the surrounding pressure the inner chamber created by the fixed sleeve and the valve of the system, the arrangement being completed with a deflector screen that limits the upward stroke of the sliding sleeve and the corresponding sealing gaskets that guarantee the tightness of the device.
