METHOD AND APPLICATION FOR PREVENTING FLASHBACK IN PREMIX GAS BURNER SYSTEMS

摘要

Automatic regulator for mixing liquids, characterized by comprising a sliding bulb sandwiched in the main liquid stream, provided at the end corresponding to the reception of the kinetic action of said stream with a closed front surface intended to cause an appreciable reduction in section of passage, which slides in a fixed housing provided with an annular chamber that surrounds the one in which the liquid to be added is injected under pressure, which penetrates inside it through several ports in the form of an isosceles triangle made in said bulb, whose passage section is variable according to its position, being added to the main current by a nozzle located at the end opposite to that of the reception of impact, reaching at all times a position of equilibrium corresponding to the equalization of the kinetic actions developed on the same by the mainstream in the sense of this, and in opposite direction by the additive current, each one given by respective values depending on constant terms according to the dimensional characteristics of the apparatus and the nature of the liquid, and a variable term corresponding to the quadratic value of the respective speeds of the current of liquid, in free vein in the main stream and in the emission nozzle in the additive one, which are, in turn, proportional to the respective liquid flow rates.
