Abstract

Dispozitivul conform inventiei se refera la reglarea debitului de lichid printr-o conducta mare (peste 300 mm) în instalatiile de transport al apei si altor lichide. în scopul reglarii debitului de lichid printr-o conducta, variatiile debitului sunt preluate de un traductor, care printr-un regulator bipozitional, comanda doua electroventile, modificand cu efect continuu volumul unei perne de gaz, sub presiune sau sub vacuum, creata la partea superioara a unei portiuni orizontale a conductei si alumentata de la o sursa exterioara. Procedeul si dispozitivul conform inventiei permit aplicarea sistemelor de reglare prevazute cu regulatoare bipozitionale la debite cu variatii mari în intervale de timp mici si care necesita un grad ridicat de precizarea reglarii.The device according to the invention relates to the regulation of the liquid flow through a large duct (over 300 mm) in the water and other liquid transport installations. In order to regulate the flow of liquid through a duct, the variations of the flow are taken over by a transducer, which through a bi-directional regulator, controls two electroventile, continuously modifying the volume of a gas cushion under pressure or under vacuum created at the top of a horizontal portion of the pipeline and an altered from an external source. The process and the device according to the invention allow the application of control systems provided with bi-phase regulators at high variance flows in small time intervals and requiring a high degree of regulation.
