Nozzle for controlled outflow of gas, provided with a check valve and accumulation bell to form bubbles suitable for remixing of stagnant liquids

摘要

The invention consists of a non-return valve, a calibrated nozzle and a bell. It finds application in the field of hydraulics, specifically the mixing of liquids by entrainment through insufflation of gas bubbles of appropriately adjustable volume. The novelty of the solution consists in the fact that, by appropriately varying the clear cross section of the bell in the design phase, one can produce bubbles of controlled dimension; furthermore, having a check valve prevents the return flow of the liquid in the lines when pumping is absent; the presence of a calibrated nozzle allows fine control of the outflow of gas and allows it to be used in low- power systems such as those powered by photovoltaic energy.
